Lu Wenhuan has been trying his best to hide his expression since he came out of the big account of the Chinese army, so that after hurriedly ordering the commander's order, when he drove a few steps back to his camp, his right hand hidden in his sleeve was still trembling slightly.

No one knew better than him the power of the things outside the camp, and when he saw those tall wooden shelves, he couldn't help but think of the memories of the old days. In just a few shots, the tall city tower collapsed, and Lu Wenhuan's mind once again appeared in his mind the wolf bèi when he was rescued by luck, and in the collapsed ruins, there were several old soldiers who had followed him for many years and were loyal.

This thing was called "Western Regions Cannon" when he was still a Song person, and the Yuan people used to call it "Huihui Cannon", and later it was renamed "Xiangyang Cannon". When the handsome Boyan said these three words, his eyes seemed to skim himself. Thinking of this, Lu Wenhuan picked up the cold tea in the tent and poured a few sips.

On the docks, boats kept coming in, unloading the grain and timber they carried, and then carried them to the front by the sergeants, where they were handed over to the Hui craftsmen to assemble huge wooden shelves under their guidance.

Outside the Yuanren camp outside the west gate, there were almost hundreds of similar wooden shelves being assembled, and Boyan was standing close to watch surrounded by a group of generals, and a middle-aged man in colorful clothes was explaining something to him in Turkic.

Zhenguo Shang_ General, Hui Hui gunner Marshal Buber, is the eldest son of the original gunner Wan Hu Yisi Mayin, since the attack on his father's position, in the southern campaign has made many achievements, here hundreds of Hui gunners and all kinds of materials are brought by him from the rear.

"Here, and here, there are a hundred each, and there, too, a hundred, and when all the ships are unloaded, two hundred can be arranged elsewhere." Buber pointed to the distance and said, Boyan nodded frequently, five hundred Xiangyang cannons, will mainly focus on the west gate and the south gate, these two places are also the focus of his prepared attack. The rest of the gates are diversion attacks.

"It's just that this stone bullet still needs to be bothered by the commander, in the previous battle, a lot of fire bombs and earth-shaking thunder were consumed, I have already sent orders to the rear, but it will take some time for them to arrive." In addition to the cannons he brought this time, Buber also collected some suitable ammunition from the Song people's arsenal, but the quantity was limited.

Boyan's eyes were fixed on the nearest Xiangyang cannon, the entire gun mount had been installed, and a group of people were putting the long cannon shaft onto the horizontal axis on the bracket, this shaft could be rotated, and if the cannon shaft was thrown, it would also move.

On the shorter end of the barrel hangs a large box filled with sand as a counterweight, and this chest, which will eventually weigh several tons, will be the power of the entire cannon, and when it falls freely, the stone projectile tied to the other head will be thrown with great force.

Fortunately, the general did not bring all the stones from the nearby mountains into the city, otherwise he would not know where to find so many stone bullets to throw. Bo Yan smiled bitterly, hoping that the power of this Xiangyang cannon could scare the guards, otherwise just the moat outside the city would have to fill in how many lives would have to be filled in.

"The order is to go down, the Han army and the new annex army each send 20,000 people, take turns to collect stones, each commanding the army of 10,000 households, and 1,000 households should be personally supervised and not neglected." Boyan turned around, pointed to Shishou Mountain in the distance, and gave orders to his cronies.

In the West Gate Tower of Jiankang City, Jin Ming, Jiang Cai, Liu Shiyong and Yuan Hong were all recruited here by Liu Yu, and after seeing the situation outside the city, the four of them were a little uncertain. Among these people, the only one who had ever seen this kind of cannon fired was Jiang Cai, so Liu Yu looked at him and asked.

"Jiang Dutong, if you see it, how far do you have to set up a Tartar cannon to directly hit the city wall?" Hearing Liu Yu's words, Jiang Cai didn't answer immediately, and looked out of the city intently, as if recalling the scene of that day.

"The Tartars set up a cannon on the bank of the river and hit the center of the river directly, so from this point of view, there should be a distance of about three hundred steps, if you want to hit this side, you should push it to that place." Jiang Cai pointed to a small slope outside the city, Liu Yu raised his telescope and looked over, his heart sank, that distance had exceeded the maximum range of the three-bow bed crossbow.

The largest seven-tip catapult in the city has only half the range, and can only be used to hit siege teams, let alone other equipment. In this way, unless the trebuchet was immediately put into the future, it would not be able to threaten the enemy.

"Evacuate the people at the west and south gates near the city walls at once, and do the same if the Tartars deploy their cannons outside the other two. After removing the catapults placed on the enemy platform and moving the bed crossbow to the female wall, all the defenders at the sheep and horse wall immediately withdrew into the city. ”

Liu Yu made a quick decision, since there was no way to destroy them, he could only shrink his forces and minimize losses. Anyway, in the end, the Tartars will have to rely on people to get to the city, and then their return cannon will not shoot at them.

The four of them were ordered to go back to arrange, Liu Yu also conveyed his own orders, with the assistance of the forbidden army, some of the people whose houses were too close to the city wall were persuaded to move to the center of the city, and he himself was ready to go back to the afterlife, and the little follower Jin Pheasant slave was left in the west gate by him in the name of superintendent.

"What do you say, the finished product hasn't been produced yet? What about the sample last time, what, dismantle, what, sue them, work overtime to produce for me, and I will pay for early delivery. Hearing Yu Zhongming's words, Liu Yu couldn't help but have a headache, what kind of efficiency is this, it doesn't seem to be a complicated thing at all.

He regretted a little that he didn't set the time tighter when he signed the contract, and he was so passive now, what should he do now? Drive a heavy truck and destroy those wooden shelves, no, if you break down, you will be in trouble. Thinking of risking his own life, Liu Yu shook his head.

With the thickness of the wall of Jiankang City, it should be able to withstand the impact of stone bullets, thinking of the large number of return cannons on the Tartar position that he saw during the day, Liu Yu's confidence began to waver a little again.

When eating, there were only two people, him and Su Wei, Liu Yu found that since the fat man got married, it seemed that he had never seen him again, and every time he came back, he was outside. asked Su Wei, she didn't know what the fat man was doing outside, Liu Yu couldn't help but shake his head.

From now on, the battle to defend the city is about to start, and he can no longer spend the night in the afterlife, only a little rest, Liu Yu drove back to Jiankang in a truck full of goods, this time the goods were mostly bottled liquor. This was ordered by Su Wei in a local township enterprise that was not well-known, although it was cheap, but it was indeed made of grain, not industrial alcohol.

Standing on the school field of Jiankang City, the villagers on the side were unloading the car, the strong aroma of wine made the group sniff, Liu Yu looked at the clear night sky, the stars were dotted like pearls on the velvet brocade.

"Hey, Taishou, what do you think it is?" A villager carrying a box of liquor said suspiciously.

Liu Yu followed his eyes, and in the direction of the West Gate, a red dot suddenly appeared in the black night sky, and it was moving quickly towards the city, is this a meteor? Liu Yu couldn't help but be stunned.
