When he first saw the Ming army outside the city, Yunyang's guards felt dizzy for a while. Not only did the opponent complete the cave attack at an unimaginable speed, but it was also an unprecedented cave attack mode, and the city wall was not collapsed downward, but was blasted into the sky. If it was the kind of cave attack in the past, not to mention the huge failure rate, even if it was successful, no matter how badly the city wall collapsed, it would not leave the defenders without the terrain to use.

But now, the Yunyang defenders standing on the flat ground can see the Ming army in the distance, which is also on the flat ground, without any obstacles, and the Qing defenders deployed nearby have completely lost their combat effectiveness. If the Ming army attacked immediately, they could rush into the city through this gap, which had no ability to resist at all, and the defenders were almost instantly knocked down by this great fear.

Although Huguang's Jīng Rui troops had been transferred south to Yunnan, Guizhou, and Liangguang, these Qing generals who were deployed on the front line and kept in contact with the Ming army were not mediocre. Whether it is Yunyang, Gucheng, Jiangling, or Xiangyang's defenders, they are all veteran military affairs with many years of combat experience and know how to attack and defend various cities. When the Qing army in Huguang sent Jīng Rui south, these experienced generals were the backbone of the resistance to the Ming army in Kuidong, ensuring that the Ming army of Sichuan and Hubei could not advance so that the Qing army of the Yungui generation could fight with peace of mind.

"Someone!" After the initial panic passed, Yunyang's defenders immediately realized that the situation was not irretrievable, and although it was not known why, there was no doubt that the Ming army had made a big mistake by not attacking at the first moment. At that time, the smoke and dust were billowing out, and if the Ming army rushed into the city, the Qing army was likely to see it clearly, and when the guards and prefects of Yunyang ran to the scene, they might be caught red-handed by the Ming army. Thinking of this, the guard immediately broke out in a cold sweat and shouted: "Plug the gap, don't let the thieves rush in." ”

The Yunyang guard quickly pointed to the battlefield and shouted to the guards beside him: "Bring in half of the archers and guard both ends of the gap." ”

Archers were often deployed near the city gates. The gates are usually the most dangerous place to be attacked, as once they are captured, the attackers can enter the city unimpeded. But the most dangerous thing in Yunyang City now is this gap, the passage here is almost as wide as the city gate, but there is not even a gate.

While anxiously waiting for the archers to arrive, the defenders had been silently praying that the Ming army would not launch an offensive immediately. The defender's prayer was fulfilled, and until he brought in a large number of clear troops from other areas, and the two ends of the gap were occupied by dense archers, the Ming army still showed no sign of attacking.

"I'm so lucky, it's really a bodhisattva's blessing." The Keeper wiped the dense beads of sweat from his forehead. He found that the trenches outside the gap had not been filled in by the Ming army, which added a considerable advantage to the defenders.

General Shouqing has carefully checked the situation at the gap. If the city wall collapsed in the past, the city wall could be repaired quickly and urgently, but this time the Ming army destroyed this section of the city wall too badly, and it seems that it can only repel the Ming army's offensive first, and then completely rebuild this section of the city wall after the Ming army retreats.

At about the same time that the Qing generals saw the Ming army through the smoke and dust, the Ming army also saw the gap in the city wall.

Seeing such a big hole exploded, Yuan Zongdi and Liu Tichun were stunned.

Today's gap was better than all the cave attacks they had seen before, and it was simply perfect. However, the Ming army was not ready to attack, and most of the soldiers were still scattered in their respective posts or camps, and had not been assembled. Before the blasting, Liu Tichun didn't think that the chances of success were great, so he didn't make any preparations, and he didn't think about taking the opportunity to capture Yunyang City.

If the Ming army had used the smoke from the blasting to attack, Yunyang City might have been lost by now. The Qing garrison did not understand why the Ming army did not act like this, he did not know, and the Ming army did not know what had happened to the city wall until the smoke cleared. It was after the smoke cleared that Liu Tichun and Yuan Zongdi reacted from the shock, and the first thing they thought of was defense rather than offense.

In the past, if the Qing army wanted to make a big move, it could only come out of a few city gates, and the deployment of Liu Tichun and Yuan Zongdi was also based on this premise. But now the sudden opening can allow the army to enter and exit quickly, Liu Tichun and Yuan Zongdi are not the slightest prepared for this, if the Qing army in Quanyunyang suddenly rushes out of this gap, it is very likely to catch the Ming army by surprise.

While the defense was in full swing in Yunyang City, the Ming army outside the city also hurriedly adjusted its deployment and strengthened the monitoring of this sudden opening.

After being busy, Yuan Zongdi, Liu Tichun and Deng Ming had a heated discussion about this acupuncture attack. Deng Ming could not teach them the principles of chemistry and physics at once, so he had to use metaphors such as blowing air and smashing a water tank to try to make them understand why he succeeded and Liu Zongmin failed.

Not only the three of them participated in the discussion, but also all of Deng Ming's guards, Liu Tichun and Yuan Zongdi's large number of guards and staff. The discussion was basically a hall of Deng Ming's words, and everyone took Deng Ming's method to heart, and everyone quickly agreed that it would be necessary to use the tunnels being excavated to conduct several more blasting tests.

Liu Tichun was overjoyed, and suddenly became obsessed with this tactic, firmly remembered the name given to it by Deng Ming, and repeated the word "blasting" countless times. Liu Tichun used all the gunpowder he brought this time to conduct tests, if he could master the blasting skills, then it would be simple to attack the city in the future, as long as the city wall was blown up, then it would be difficult to capture the city?

Yuan Zongdi had long thought that Deng Ming seemed to have a special power over fire, so he was not as excited as Liu Tichun. Yuan Zongdi faintly suspected that a realm would be formed around the third prince, and in this realm, everything related to fire would become very powerful. Liu Tichun selected a group of confidant officers to learn blasting with the third prince, and Yuan Zongdi also sent a few, but he secretly made up his mind that in the future, when the third prince was away, he would do a few blasting tests alone to see if this trick was still effective.

Under Liu Tichun's urging, it didn't take long for another tunnel to be dug under the corner of Yunyang City. Now the Ming army does not consider digging the tunnel very wide, as long as it can ensure ventilation, it will dig forward vigorously. Soon, another coffin was filled with gunpowder and sent in. Deng Ming was ready to go down to the tunnel again to command the seal, but Liu Tichun said that he didn't need Deng Ming to go down in person, he had several soldiers who had seen Deng Ming's methods, and this time those soldiers would do the finishing work.

These soldiers made the fuse according to the cat, handed it over to Deng Ming for acceptance, and then began to build a wall in the tunnel. This tunnel is much narrower than the last one, so the hole is blocked quickly, and the Ming army in the tunnel has sealed the tunnel tightly. Deng Ming proposed that there are some areas that need to be improved, but Liu Tichun believes that the most important thing now is not to improve, but to master this craft first, and all the arrangements strive to be exactly the same as the previous one.

When the Ming army was preparing for the second blast, the Qing army did not notice it, and all their attention was focused on the first gap. After the city wall was bombed, the prefect of Yunyang hurriedly mobilized the people in the city and collected a large amount of timber to build a fence behind the gap. When this gap first appeared, the people in the city were panicked, and many soldiers thought that the city was about to be broken, and they were already thinking about a way out, and the people were hiding at home and refused to come out; Seeing that the sluggish Ming army did not rush into the city, the prefect and the guards celebrated each other, and the fighting spirit of the soldiers gradually recovered. As long as the Ming army gave them some more time, they could completely erect the fence, and when the Ming army attacked the gap again, there were archers on both sides of the head who were waiting for battle, and the front would also meet the resistance of the Qing infantry who relied on the fence to defend it.

Once this fence is completed and the prefect survives the day, the prefect will organize the people to make large wooden cages, load stones in the wooden cages, and temporarily fill the gaps to prevent the Ming army from entering. At present, the Qing court is also selective of civil officials on the Huguang front, and it values not only how well the articles are written, but also a certain amount of actual combat experience.

The two civil and military ministers of Yunyang are busy behind the gap, one supervising the war and the other supervising the work. Sooner or later, the Ming army would attack from this weak link, and what was happening in the rest of the area would not be taken into account for the time being - until another thunderclap burst from behind.

……

"Not bad, not bad!" Seeing that another section of the city wall that had been blown down appeared, Liu Tichun's face was full of satisfaction. This method of cave attack is relatively small, the progress is fast, and the effect is obvious: "There is no need to dig deep at all, as long as you can stuff a coffin under the wall base." ”

Liu Tichun turned around with a lingering mind, and asked the guards about the progress of the excavation of the tunnels under the other mounds, intending to blast it again, so that the subordinates who had just learned this technique could review it again. He planned to try the improvements that Deng Ming had said, and the charge would be appropriately reduced.

However, several other tunnels are still far from the wall foundation. The first two blasting tunnels started at about the same time, so the progress was not too much.

"It's going to be tomorrow at the earliest, or even the day after tomorrow." Liu Tichun carefully inquired about the progress of several tunnels, estimated the time in his heart, and turned to Deng Ming and said. Liu Tichun plans to transfer all the teachers who are teaching in various tunnels together, and the excavation speed will naturally be accelerated.

"Can this blasting be done at night?" Yuan Zongdi asked.

Liu Tichun's heart tightened when he heard it, and he felt that Yuan Zongdi had asked the point. According to his thoughts, it should be heavy yang qi during the day and yīn qi heavy at night, which really can't be generalized.

"Absolutely." Deng Ming smiled: "Can't you fire at night?" ”

"At least not accurately." Liu Tichun also laughed after finishing speaking: "But our blasting has already made a hole and stuffed the coffin under the city wall, so we can't stop it." ”

……

After discovering that the second gap appeared, the guard's heart that had just relaxed a little bit suddenly tensed again: "It turns out that the thief wants to go both ways!" ”

There is no need to defend the city wall that is still intact for the time being, because the two large open openings are placed there, and the Ming army will definitely not climb the city wall after being full. However, the gates could not be left unguarded, and the defenders ordered that only the minimum number of defenders be left under the four gates, and the rest of the soldiers were divided into two teams and deployed behind the two openings at the same time.

The Ming army soon found that the entire city wall was empty, so Liu Tichun immediately decided not to dig tunnels, and directly sent troops to run through the trench and began to cut the corners of the wall, just set up a shed on the head to prevent stones from falling from above. This kind of excavation is much simpler than the tunnel, does not require a lot of manpower, not to mention the complex tunnel ventilation, carrying soil and stone and other problems, the Ming army formed several groups in one breath, distributed under the Yunyang city wall and began to dig holes at the same time.

After the second gap appeared, the defenders wavered again, and under the desperate persuasion of the defenders and the prefect, they finally stabilized the hearts of the people again. The prefect did not bother to further strengthen the fence behind the first gap, and began to build the fortifications behind the gap in the new wall, which was busy until late at night, when it was finally completed. He had not rested for ten hours, and the work of supervising the construction of wooden cages awaited him, and since the openings became two, the need for wooden cages would be doubled.

The prefect promised the migrant workers who built the wooden fences that when the fences were repaired, they would each have a full meal and broth before they started building wooden cages.

In any case, the prefect did not expect that before the migrant workers could get this full meal, the Ming army carried out a third blast. In the second half of the night, it happened a fourth, and by the early morning of the next day, it had a fifth.

The prefect's eyes were bloodshot, and the carpenters and the people they had recruited had already dispersed, and there was no way to call them out from behind the closed door, and even the officials of the government fled home with the people. Many of the auxiliaries who assisted in defending the city were locals, and they reacted in the same way as the officials. Some of the auxiliaries who had been found from outside the city hid in the homes of friends they knew, or took advantage of the chaos to escape from the city.

The Qing army now had to defend four gates and five gaps, and after a large number of auxiliaries fled, the Qing army appeared even weaker. Originally, among the more than 1,000 soldiers in Yunyang City, 800 were assigned to the four city gates, and each city gate had more than 500 auxiliary soldiers to assist in the defense; Now, after continuous redeployment, there are only about forty soldiers in each gate, and these soldiers have no confidence in defending the gates, and their combat efficiency will be greatly affected by the lack of auxiliaries. If the rest of the auxiliaries run out, the soldiers will have to go to the city to carry wood and stones to the city walls, and they will have to find food themselves.

In fact, the Ming army's blasting operations were not more than three times, and several times failed, so the Qing army did not notice. During these operations, the Ming army experimented with many new methods and reduced the amount of gunpowder. There was only a little bit of gunpowder left with Liu Tichun and Yuan Zongdi, and Liu Tichun would not stop blasting until he used them up completely.

As for Yunyang City, the city walls were blown up in pieces, and there were gaps everywhere, which was already in the bag in Liu Tichun's eyes, so he was not in a hurry to attack. At the moment, He Jin was not in the city, so he led his troops to the suburbs to collect supplies. Liu Tichun thought that there would be street battles when attacking the city, and without He Jin, the advantage of the Ming army was not big enough, and he planned to wait until He Jin returned to Yunyang before attacking, and at present, as long as he continued to blast the city wall.

Although there was not enough gunpowder left, how to excavate efficiently also needed practice, and the battlefield needed to quickly dig out the potholes used for blasting.

There were only forty-one soldiers and more than 20 auxiliary soldiers left on the south gate of Yunyang, and when they saw a group of Ming soldiers carrying hoes and walking not far from the city gate to dig the foundation of the wall, they opened the city gate and surrendered to the Ming army without thinking too much. The Ming army accepted their surrender, took control of the city gates, and sent a report to Liu Tichun. After Liu Tichun sent soldiers to take over the city gate, the original Ming army went out of the city and continued to dig the corners.

After the prefect of Yunyang learned that the south gate was lost, he walked into the yamen alone and hanged himself. When the news of the prefect's death reached the ears of the guards, he knew that the general situation had gone and the fall of Yunyang City was a foregone conclusion.

For a general of Wu Sangui's level, the Qing court may not hold him accountable, but for Yunyang Shoujun, a small new general, losing the city and losing the prefect means asking for beheadings and raiding the family, and only dying in Yunyang may be able to seek a glimmer of life for the family.

The armies scattered in the various gates and gaps had lost control, and the Yunyang staff had no choice but to gather all the family members, personal soldiers, and the equally desperate henchmen and officers, and take this army that could barely control the zhì, ride all the war horses they could find, and fight out of Yunyang City, ready for the final battle to the death.

Before his final blow, the general conducted a serious reconnaissance and selected the target at the position of the Ming army's general flag. If a miracle happens, and the general of the Ming army can be killed, maybe the situation in Yunyang can be reversed, or he can escape with the head of the general of the Ming army and atone for his crimes.

As soon as this Qing army left the city, it was immediately discovered by the Ming army, and soon Liu Tichun, Deng Ming and others got the jǐng report. Liu Tichun was discussing his experience with those demomen with great interest, and asked Deng Ming a few questions from time to time.

"More than fifty cavalrymen, and about a hundred infantrymen, under the banner of a general, are coming here?" At present, the general flag of the Ming army is not far from the city wall, and Liu Tichun let out a sneer when he heard the news: "Is he going to fight hard?" ”

"Sir, let the lowly go and investigate." Zhao Tianba said. He wasn't as interested in blasting as Liu Tichun, and his favorite thing was fighting. In the past few days, Deng Ming has been circling around the Yunyang City Wall all day long, and Zhao Tianba, as a personal guard, has no choice but to follow.

"Okay." Deng Ming nodded and agreed that Zhao Tianba would go to find out the enemy's situation.

Zhao Tianba flew on his horse and left with a few of Deng Ming's guards. Although many of Deng Ming's guards were born in the Sichuan army, most of them followed behind Zhao Tianba during the Battle of Wanxian, and other people had also heard of this person's martial arts and were convinced by Zhao Tianba.

……

The general of the Qing army saw that the Ming army in the distance seemed to begin to adjust its formation, and the men and horses around the opponent's general flag were countless times larger than his small group of Qing troops. In the general's view, only one surprise attack might be able to gain a slight advantage. Just as he was about to lead the army to kill the general, Yu Guang suddenly saw several Ming cavalry rushing towards him.

The general looked fixedly, there were a total of six Ming cavalry, except for the leading Ming army, the remaining five Ming troops all had jīng silk cloaks, and the cold light under the cloak was all iron armor. The leading Ming army was dressed in ordinary armor and an old cloth cloak.

"I am Jinyi Wei Qianhu Zhao Tianba!"

The Ming army led by the Ming army shouted, and shot at the Qing army. The general also shouted loudly, and stepped forward, and the spear in his hand stabbed at the knight headed by lightning like a poisonous snake, full of thought that he could kill him in one fell swoop. But with a swing of the opponent's spear, the tips of the two guns collided, and the general only felt that the force coming from the barrel of the gun was incredible, and he immediately pulled his gun away, and flew away, and before he could react, the bright spikes were already approaching, just between his eyes......

After Zhao Tianba left, Yuan Zongdi and Liu Tichun adjusted their formation and prepared to fight. They thought it might be the enemy's last fatal blow, and although there were not many of them, they were not to be taken lightly.

He had just spoken two short orders, and before the herald could convey them to his troops, he heard thunderous cheers in the distance.

"What's wrong?" Yuan Zongdi and Liu Tichun turned their heads in confusion. However, they were affected by the city walls and the surrounding army, and now their vision is not good, and they can't see clearly for a while. Of course, it won't be a bad thing, because this cheer was made by the Ming army in front.

In waves of cheers, Zhao Tianba carried a bloody human head and led the other five guards back to the general's flag. Zhao Tianba jumped off his horse, strode in front of Deng Ming, and threw the head of General Yunyang in front of Deng Ming's feet. His face was calm, and his tone was not alarmed: "There are 155 people who come to the enemy, 21 people of the inferior rank are killed, and the rest are all surrendered." ”

"I'm tired." Deng Ming smiled. The war in Yunyang seems to be over.

The prefect committed suicide, the main general was killed in battle, and the rest of the Qing soldiers surrendered to the Ming army. Originally, Yuan Zongdi wanted to send someone to urge He Jin to quickly lead his troops back to the city to prepare for street fighting, but now there is no need for this. Liu Tichun immediately sent someone to take over Yunyang's arsenal, and he was extremely happy to find that the gunpowder was intact, and the gunpowder he brought had been exhausted, but as soon as Yunyang surrendered, he had everything, and there was more gunpowder stored here than the Ming army had brought.

Liu Tichun plans to experiment with a direct blasting of the city wall. Liu Zongmin's failure still haunted him, and now with Deng Ming's inspiration, he plans to try to seal and blast the wall. Yuan Zongdi saw that the situation was not good, and hurriedly divided the gunpowder into three parts, Liu Tichun continued to study and blasted the city wall, but he could not embezzle the two parts that belonged to him and He Jin.

……

In the afternoon of the same day, He Jin returned to Yunyang with joy, he felt that the trip had gained a lot, and it seemed that the work of the Yunyang Qing army had not been done thoroughly enough.

After seeing Yunyang City, He Jin's smile turned into surprise, in front of him was a ruined wall, and the red flag of the Ming army was flying on the head of the city, and it was no longer the green flag of the Qing army.

"What exactly did they do to Yunyang? I've only been gone for two days, right? It's only two days. He Jin shouted to the guards beside him-
