After Chang Yu returned to the city, he immediately convened the generals to discuss military affairs, and the thief army used the terrain to build the position fortifications impregnable, which made the attack more difficult, even if there was artillery blessing, it would have to pay a heavy price, this kind of battle to fill the pit with human lives Chang Yu easily did not fight!

"A tooth for a tooth, we can also build a stone thrower to deal with it, and it is unbearable to get a few hundred to smash the thief army" Ma Ke took the lead in putting forward his own suggestion and was echoed by everyone, which is indeed a good way, but it is not realistic to build hundreds of planes in one go, and getting dozens of planes can also suppress the thief army, and the worst can also fill the gap in artillery.

Knowing that the Shenji Battalion would come to help in the battle, everyone proposed to reward the firearms craftsmen in the city with a lot of gunpowder while the sky was dark.

In fact, it is not difficult to make gunpowder, even he knows that one nitrate, two sulfur and three charcoal, the difficulty is to collect materials, charcoal and sulfur are still easy to do, but the nitrate is not very easy to do, to find saltpeter mines, or find another way, such as the toilet or the corner of the pigsty that layer of white crystals, the simple formation process is that the pigsty, toilet and other nearby soil contains a large amount of organic matter, these organic matter decay, and then through the action of nitrifying bacteria, nitric acid is generated.

Nitric acid further reacts with arsenic, magnesium and calcium in the soil to form potassium nitrate and calcium magnesium nitrate, which is fire nitrate, that is, saltpeter.

However, the amount that can be obtained by this method is too small, but for Chang Yu, ant legs are also meat, he came from later generations, and he attaches more importance to the use and development of firearms than anyone in the Ming Dynasty.

Reward, but all those who can make gunpowder and make firearms in the city are hired with a lot of money, even if it is not a popular thing, we have to buy horse bones, Chang Yu knocked on the table, and someone went to the city to announce it.

It was close to noon on the day of this discussion, and the generals hastily ate lunch and then returned to the camp to Zhang Luo, and soon there was an uproar inside and outside the city, and the craftsmen who could produce brave men and professionals under the heavy money flocked to the city, and a large number of soldiers and people went out of the city to cut down wood and build cars, and at the same time sent dozens of troops to patrol and not allow the thieves to explore the horses and get close to the city for ten miles.

In fact, the thief army does not need to reconnoiter nearby at all, because there is a hill three or four miles southeast of Tongling City, which is locally called Bijia Mountain, and Chang Yu believes that there must be a lookout post on the top of the mountain at this time, staring at every move outside Tongling City.

That's why he asked Guo Ren to lead the team out of the city from the north gate before dawn, because that was the time when people were most sleepy and careless.

The 200 people led by Guo Ren were selected from the Dongchang Guard and Chang Yu's personal guard battalion respectively, because the reputation of each battalion was the elite of the elite, many of whom had strange skills, some were good at learning birdsong and beast language, some could observe astronomical directions, some were good at concealing and tracking, and some had noses sharper than dogs, and Guo Ren picked out fifty marksmen from the guard battalion.

Two hundred men can be said to be armed to the teeth, except for a small amount of dry food, steel knives, daggers, strong bows, and no less than twenty arrows.

When the sky was bright, he led the team to quietly go out of the city from the north gate and went straight to the northeast, and did not encounter the thief army to explore the horse for ten miles, so he hid the war horse in the woods by a lake and turned around and sneaked to the southeast.

After walking for a few miles, the sky was already bright and the sky was rising due east, and the tenacity made it so difficult to divert due south and go straight to the valley.

The trees in the valley were lush and cool, but there were no roads under their feet, rocks and weeds, and everyone had to march carefully.

When it was close to noon, everyone estimated that the distance should be directly east of Tongling at this time, but it was just separated by lofty mountains.

Seeing that the soldiers were a little tired, they scattered under the bushes to trim and eat, and a strong man from the black wolf battalion walked over gently: "Commander, if you go further, I'm afraid that you will enter the open stake and secret outpost of the thief army, and it will be easy to be discovered if we march together."

Guan Ren nodded: "Since you have proposed it, do you want to take the lead" The man smiled: "I have a few brothers who are good at reconnaissance and lurking, and they want to open the way ahead!" ”

", you just want to fight for merit" At this time, a man from the Black Tiger Battalion also came over: "The commander of the situation can learn bird calls, and I can find the way in front to warn ......"

After a while, there was a group of people around him, all of whom asked for the order to open the way, and you and I fought endlessly, although the sound was not loud, but it was also noisy and people's brains were buzzing.

However, he had his own way, and ordered the four battalions to be divided into four roads to select a leader each, and then spread out to march so that the target was small and not easy to be discovered by the secret sentry of the thief army.

The valley is getting deeper and deeper, and it is getting more and more dangerous, and the people can only hide their whereabouts, and they can only drill into the forest, and they also have to guard against the light and dark sentinels of the thief army, and the journey is very slow, and they only walk until noon, but they are tired and sweating profusely, so they find a hidden place to spread out and rest their breath.

A henchman next to him took a branch and pulled this on the ground: "Head, this is Tongling City, separated by a few mountains, we are in this valley, this valley is 100,000 mountains to the east, and it is estimated that it is the big lake that Wang Tizhong said, so it is useless for us to go to the end, and if we walk seven or eight miles, we will go over the mountain in the west, and the nest of the thief army is over there."

Guo Ren nodded: "The closer you are to the thief's nest, the more difficult it is to walk, how can you be cautious with thieves, the devil knows how many eyes and ears they have planted in this mountain......"

While he was talking, he suddenly heard the sound of birds chirping in front of him, and everyone suddenly became nervous and fell silent, because this was a warning code!

, this is just about to enter the mountain, didn't he run into the thief's secret whistle, he was so nervous that his fists clenched, he was not afraid of fighting, but worried that exposing his whereabouts would make the little eunuch's plan abort.

When he was restless, a person came out of the grass in front of him: "Commander, there is a small village 100 meters ahead, which is estimated to be inhabited by hunters, and his subordinates have found a thief army in the village."

There are hunters living normally in the mountains, and the thieves are dressed up like ordinary people, and the spies are angry with one sentence: "Doing evil!" ”

"Give a code to the back and let them lurk still," he gritted his teeth: "Let's go over and have a look," he said, bending over and cautiously touching the front.

It is said that there are only three or four small villages, a few thatched houses are dilapidated, there are some animal skins on the low stone walls, an old woman is cooking under the stone wall, and an old man is kneeling at the door of the grass hut and wailing and kowtowing: "You will be cursed by heaven like this, you will not die well......

A man with a fierce face walked out of the grass hut and kicked the old man over with his pants and legs: "Old immortal, I won't take your sacrificial knife if I am happy today" said and turned his head to the house and smiled: "Fan Laosi, you guys hurry up, the meal will be ready...... That old witch, when will the rice be cooked? The old woman was so frightened that she didn't dare to say a word, the man snorted, turned his head and looked at a nearby household: "Look at Nima, the eyeballs will be gouged out for you" The family quickly shrank their heads and closed the door.

In the grass on the hillside next to the village, looking at the red eyes, his subordinates were about to rush over and slaughter them, and he grabbed them: "Here is a few hills away from the thief's nest, they have come here, it seems that the old thief Baiwang has long been willing to guard against us, and he has spread his ears and eyes so far, it is not difficult for us to kill these people, but I am afraid of alarming other thieves."

"Captain, they're inside...... There was a woman wailing in the room before, but now there is no sound......" A soldier of the Black Tiger Battalion gritted his teeth, and interrupted him in a low voice: "I know, but the overall situation is important......" As he was talking, he saw that the thief suddenly pulled out an eleven or twelve-year-old boy from a house and slashed him: "Fuck, dare to bite Lao Tzu, what Lao Tzu wants......" Before he finished speaking, he screamed and fell straight to the ground, and he couldn't help but shoot through his brain anymore!
