"This is a strategic reserve, use a little less, are you really sure you want to use it here?" Qian Tiandun questioned: "TT, we can't make this thing in a short time, right?" "Large-scale production is definitely not possible at this stage, but the real room can be prepared in small quantities, and trinitrotoluene is not a rare thing...... For more up-to-date chapters, visit wèn:. When it comes to chemical issues, Qiao Zhiya can be regarded as an authority in the command: "Sulfuric acid and nitric acid can be produced by Shengli Port now." It's just that toluene is a little troublesome, and if it is to be refined from the coal tar sent from the black soil port, it can basically only be done in the real room, and the production capacity is very small. Mercury thunderate used for detonators is not a problem, and it has been trial-produced last year, but the stability of the use of the dìng 'property' is not very good, and the Ministry of Chemical Industry has been trying to improve it. "How is the cost of this thing compared to the earth explosives 'drug' used now?" Yan Chujie immediately came to the 'spirit', if the Haihan militia can use TT as a regular combat preparation material, then the tactics that can be used in the battle in the future will be even more abundant.

"For the time being, there is no comparison, the cost of production in the real yàn room is too high, and the output is very small. I'd also like to get this thing into mass production sooner, but I'm afraid it won't be possible in the short term. Qiao Zhiya also seemed very sorry for this, but he quickly brought the topic back to business: "I carefully observed the structure of the peace 'gate' on the position today, in fact, it is much easier to blow up the peace 'gate' than to blow up the city wall, there are three 'gates' and 'holes' under this city tower, and the stressed structure is much weaker than the city wall. ”

Yan Chujie shook his head and said, "The question is, how did you go over to construct and arrange the bombing point? Not to mention the defenders on the city tower, there is still a moat in between." Do we have the militia carrying the rafts to fill the river? And our sappers may not be able to understand the structure of the force and the like. ”

"Ordinary sappers will definitely not be able to do this kind of technical work...... Qiao Zhiya looked at Yan Chujie and said: "Leave this matter to me personally!"

"It seems that you have already prepared a plan of action!" Qian Tiandun replied with a smile: "Then how do you need us to cooperate with you?"

"Send someone outside the city to take all the things on the boat and send them over, and I'll pick up a few sappers who know how to 'sex' in water. Let's do it tonight, and if you go well, you'll probably be able to finish your preparations tomorrow. Qiao Zhiya said confidently.

Three hours later, several figures slipped silently out of the darkness into the moat outside the Imperial City. The moat of the Imperial City was only 10 meters wide, and the outer part of the Peace Gate was originally a two-section bridge, with a fixed pier deck on the outer side and a suspension bridge that could be raised on the inside. However, before the Imperial Forest Army withdrew into the Imperial City, they did not forget to remove all the bridge decks that fixed it, and now even if they can lower the suspension bridge, they can't reach the river bank at the other end. At this time, the other side of the 'gate' of the closed city should have been full of wooden pillars on the top of the 'gate', and maybe the other end of the 'gate' and 'hole' was blocked with stones, so they didn't have to worry about the 'gate' suddenly opening and the defenders rushing out and arresting it.

After slowly swimming across the river, these people climbed up the river bank, entered the tower, gate, and hole of the imperial city's peace gate, and after putting down the burden they were carrying, they swam back to the other side lightly. These people walked back and forth in the moat twice before transporting all the things they needed to the 'gate' and 'hole' of the tower, and then quietly lurked.

After dawn, the troops of the Haihan militia outside the city aimed several 'gates' of artillery at the city tower, and fired every few minutes or so. Although the army's small-caliber artillery could do little damage to such large structures, the deterrent effect of such an attack was very significant, and the defenders on the tower soon chose to withdraw from this too obvious target position, leaving only a small number of sentries on the walls on either side of the tower to monitor the movement of enemy troops outside the city.

Of course, a few people in the 'hole' of the city tower were not idle, they took advantage of the bustle outside, and were holding a hand-cranked drill to dig 'holes' in the city wall everywhere and plant explosives. According to Qiao Zhiya's rough estimates, they need to place dozens of detonation points under the tower in order for the tower to collapse after the explosion. It was not an easy task to make so many 'holes' in the stone bricks by hand, but it was also a last resort, and if you hit it with a chisel, it would be difficult to hide the sound from the defenders on the walls.

The militia troops outside the city did not rest on this ground, and with the exception of some who continued yesterday's demolition operation, the various companies were ordered to begin to clean up some of the government institutions in the occupied areas. The six ministries under the South Vietnamese Imperial Court, the Metropolitan Administration, the Guozijian, and the Chinthien Prison were all outside the imperial city, and there were many things of interest to the executive committee in these institutions, and there were also the residences of various imperial relatives, high-ranking officials and magnates in the city. Even if the Haihan militia does not start in these places, the North Vietnamese army will not let them go when the city is broken, and the Military Commission insists on not cooperating with the North Vietnamese army to attack the city, which is more or less the idea of eating alone in the advanced city.

With the guidance of the local leading party, the troops carrying out the mission basically no longer need to try their luck by mistake, and the efficiency of raiding homes has become very high. Although the militia had strict rules prohibiting soldiers from hiding 'personal gains' in the process, it was clear that the enthusiasm of the men in carrying out such tasks was much higher than that of forced demolition - almost everyone was as motivated as if they had loaded their own dividends after watching boxes of gold, silver, and jewelry loaded into trucks and shipped out of the city, and at the thought that they would receive their share of the dividends after the battle.

At the same time, it was not only the militia that made a fuss in Hue City, but the South Vietnamese stragglers who had won or failed thousands were doing the same thing in the other half of the city. Since the militia forces did not have enough troops to surround the Imperial City, some of the defenders were able to keep in touch with the high-ranking officials in the city on the other side of the Imperial City. However, some of the troops that were scattered during the siege have become headless flies, and as long as someone takes the lead in making a 'rebellion' at this time, someone will immediately follow suit. At first, the 'rebels' did not let go of their courage, but they just rushed into the homes of ordinary people to loot, but soon this kind of riotous 'chaos' escalated out of control, and the rich families in those high-walled compounds obviously had more oil and water, so it was natural that the 'rebels' soldiers became the main targets of the 'rebels' robbery.

"Our people have already started attacking Xicheng?" Qian Tiandun put down his binoculars and asked Yan Chujie with some doubt. In fact, you don't need to use a telescope, and you can see black smoke rising from many places in the western city with just the 'naked' eye, and you can faintly hear the sound of killing in the wind.

Yan Chujie shook his head and said, "It's not our people. ”

"The North Vietnamese army has invaded on its own?" asked Tom Wang, stunned. Yesterday, after bringing the materials needed for the blasting from outside the city, he stayed at the forward position and never left.

"Probably not, if they are going to attack the city, they will at least say hello to us in advance. Although Yan Chujie was not sure what was going on in Xicheng, he could guess a little: "Eighty percent of the defenders of South Vietnam are 'chaotic' by themselves, and there should be many people who want to take advantage of the 'chaos' to make a fortune at this time." It's okay to let them make a fuss so that no one interferes with what we're going to do. ”

The 'rebellious' army was far more strict than the Haihan officers had imagined, so much so that the Nguyen high-ranking officials in the palace had to order the surviving troops in the Tay Thanh area to quell the 'rebellious' soldiers—if they did not stop them, the city would be destroyed at the hands of the 'rebellious' soldiers, even if the Hai Han could not capture Hue in the end.

In the afternoon, there was an even more unbelievable situation in the city, as a large number of people fled from the western city and poured into the eastern city controlled by the Haihan militia to escape the 'chaotic' soldiers. Although the area was already "enemy-occupied" for the local population, it was clear that the social order here was better than that of the city controlled by the South Vietnamese army. Except for a small number of elite families, ordinary people were basically safe and sound as long as they did not take the initiative to attack the Haihan militia and did not suffer from the looting of the militia - of course, a large part of this was actually due to the fact that the militia had limited troops, and could only give priority to looting the large households pointed out by the leading party.

Most of the soldiers who were 'rioting' in Xicheng had already seen the power of the Haihan militia, and they actually gave up the pursuit of these people with a tacit understanding, and controlled their range of action outside the defense line of the Haihan militia. A small number of 'rebels' who did not see the signs also quickly retracted their claws after being fed by the militia's rifle bullets, not daring to provoke this difficult opponent again.

This unreasonable situation made the officers on the Haihan side cry and laugh, obviously they should play the role of the unjust aggressor in this war, how did the orange "color" change halfway through the war, and instead became the defender of the ordinary people?

After nightfall, the engineering detachment, which had been working under the 'gate' of peace for a day, finally sneaked back to their camp safely. When Qiao Zhiya returned to the tent of the headquarters, he collapsed on his chair, and he didn't even have the strength to change the wet clothes on his body.

Seeing this, Tom Wang hurriedly called the orderlies to get the 'wool' towel and clothes, and helped him up with Qian Tiandun to take off his clothes. After a while, Morgan also came in with a bowl of hot ginger soup: "You will feel better after drinking this, this is the unique 'door' recipe taught to me by Major Gu Wei." ”

Qiao Zhiya changed his clothes, drank ginger soup, and collapsed on the chair for a while before recovering his strength, shook his head and said: "I haven't been so tired since the crossing, when I was digging sand in Shengli Harbor to build a station, it was easier than now, I really underestimated the amount of work this time." ”

Qiao Zhiya said and spread out his hands to show everyone, both palms were red, and blood blisters had appeared in several places, and it could be seen that he was indeed tired enough to choke this day.

"How much has been accomplished now? Why don't I take over from you, you can take charge of the technical guidance, and I still have the skill of installing explosives and burying detonators." Qian Tiandun took the initiative to ask.

"No need. Qiao Zhiya shook his head lightly and said, "It's all arranged, and I've brought back the blasting fuse." The explosives haven't been used up, but the electric detonators we brought with us before the crossing are basically gone, and we can only use earth detonators to do this kind of thing in the future. ”

Yan Chujie asked in a deep voice, "Are you sure there's no problem?"

"If you can't blow up this tower, I, Qiao Zhiya, will immediately go back to Tian Du's room!" Qiao Zhiya couldn't help but grin while swearing, because Morgan was using a medical device to process the blood bag on his hand at this time.

"Let's all split up and prepare!" After Yan Chujie received an affirmative answer, he asked everyone to start preparing for the offensive they were going to take on the next day.

"Wait, do you want to inform the North Vietnamese Army?" asked Qian Tiandun.

Although the military advisory group sent by the North Vietnamese has been placed outside the city all the time, and has not even been able to enter the city so far, and all the information they have learned about the battlefield is from the verbal description of the liaison officer of the Haihan militia group, it seems that the time to launch a general offensive tomorrow is coming, and it seems a little unreasonable if they do not say hello to their allies.

Yan Chujie hesitated slightly, nodded and said, "Then say hello to them, but it's too late today, let them know tomorrow morning!"

In accordance with Yen Chujie's order, the liaison officer woke up the officers of the North Vietnamese Military Observer Corps at dawn the next day and informed them of the news of the imminent launch of the general attack on the Imperial City today. And the hurriedly 'chaotic' military observers rode around to the North Vietnamese army garrison in the west and passed the news to the desk of the commander Zheng Bai, almost two hours had passed.

When Zheng Bai was filming in the camp and scolding the Haihan people for playing 'tricks', the position of the Haihan militia outside the imperial city had entered the final stage of combat preparation. After two consecutive days of forced demolition work, quite remarkable results were achieved, and a vacant land with a width and depth of more than 300 meters was cleared outside the 'Gate' of Peace. At present, nearly 40 'guns' of different calibers are densely arranged on this open space, ranging from the 3-pounder small cannon equipped with the special operations battalion of Heitu Port to the 48-pounder mortar gun for siege, almost including all the specifications of artillery that have been installed by the army units of the Haihan People's Regiment at present.

Of course, this situation also attracted the attention of the defenders on the city walls, but they could only stare dryly now. According to the footage taken by a drone yesterday from high altitude, the defenders of the city have already dismantled several 'gates' of cannons arranged on the other side of the city wall, but it is not a task that can be completed in a short time to reach the side of the peace 'gate' and re-erect the forts. In the city, whether it is using bows and arrows to throw 'shooting' or trebuchets and other equipment, its 'shooting' range cannot reach the position of the Haihan people. Therefore, the defenders had no practical countermeasures for the Haihan people to set up artillery positions outside the city.

At this time, in the private house separated by a moat from the peace 'gate', Qiao Zhiya was waiting for the order from the headquarters. No one noticed that there were a few black lines the thickness of little fingers extending from the house into the moat, and the defenders on the tower did not even realize that they were standing on top of a large explosive bag.

At nine o'clock in the morning, after a qiē was ready, Yan Chujie gave an order to Qiao Zhiya through the walkie-talkie, and after Qiao Zhiya pressed the detonator, he heard a series of explosions coming from the downstairs of the Peace 'Gate' City, although it was not as big as the battle when the outer city wall was blasted a few days ago, but the effect of this explosion was far greater than the last time. I saw that the city tower with a height of more than 10 meters began to collapse downward before the blasting sound ended, and about five seconds later, the city tower with a width of more than 30 meters completely collapsed into a pile of rubble, and the dust and smoke flew up, completely obscuring the sight of the two armies.

After a few minutes, the dust cleared, and the sight before them shocked both sides. As Qiao Zhiya had predicted before the operation, after the collapse of the tower, both sides inside and outside the city could see each other clearly through the gap, and from the artillery positions on the Haihan side, the buildings of the Nanyue Imperial Palace about two miles away could be clearly seen, as well as the panicked defenders inside the city.

"Aim at Target No. 1 and fire!" As the officer gave the order, the artillery on the artillery position began to roar one after another, and one shell after another flew over the collapsed city tower with a screeching sound, smashing into the palace building in the middle of the imperial city.

Almost at the same time as the Peace Gate Tower collapsed, the defenders of the Imperial City began to lose the will to continue to resist, because as long as the eyes were not blind, they could confirm that the surrounding walls could no longer protect themselves and protect the crumbling regime. A large number of defenders began to flee to the west, because there was no sign of the Haihan people outside the city walls, and they still had a chance to escape.

When the Haihan militia began to erect pontoon bridges over the moat, the defenders did not resist at all, and the people were relieved and bold to connect the wooden rows on the river surface, and the militia infantry followed behind, and when the shells were still flying in the air, the soldiers of the militia had already rushed across the pontoon bridge and stepped on the ruins of the collapsed city tower.

"The city is broken! The Haihan people have come in!"

With the shouts of some of the defeated soldiers, the defenders of the city quickly lost their will to resist and began to flee. This allowed the militia to enter the imperial city without encountering much resistance, and the sober-minded defenders almost all chose to flock to the city 'gate' in the other three directions, which was the 'gate' of escape for them.

"The various companies are scattered and control the predetermined area!" Yan Chujie can only issue combat orders to the officers through the walkie-talkie. After the Haihan militia army entered the imperial city, it was difficult to cover all aspects, so it could only give priority to occupying some important targets and strive to control the leaders of the Ruan family. However, in the 'chaotic' army, it is not easy to capture the power of the Ruan family, and Yan Chujie does not want to chase too fiercely to cause a backlash from the defenders. After thinking about it again, Yan Chujie still decided to leave this piece of 'fat' and 'meat' to the North Vietnamese army who set up an encirclement outside the city. About half an hour after the Hai Han militia attacked the peace gate, the west gate of Hue City was opened, and thousands of remnants rushed to the western plain, hoping to escape into the Truong Son mountain range.
