Under the Song Division, the siege vehicles of the Song army continued to move forward, constantly approaching, and the walls of the Song Divisions had been heightened and reinforced, but these siege equipment were really behemoths, and when they were pushed forward, they were actually more than a zhang higher than the walls of the Song Division.

In terms of the volume of these things, this cannot be created by Cai Yongxian, it must have been prepared a long time ago, and before the siege, he fought with Guo Hongying and Zhang Fan respectively, and he can still keep these things intact, I have to say that he has some ability.

Wen Chengfang looked at the behemoths that were approaching him, his face was pale, and he urgently ordered his soldiers to open fire, "boom, ......boom, boom" cannon sound sounded one after another, and there was a sudden cracking sound on the siege vehicles in front, and the slightly smaller number of siege vehicles were smashed by artillery fire, and with the sound of "crunching", they collapsed violently, and the soldiers who were standing below pushing the cart screamed and ran away.

However, although the bombardment had some effect, it could not change the disadvantageous situation that Song Shicheng would face, and the front of the largest siege vehicle was reinforced with heavy iron plates, although the artillery bombardment made the siege vehicle shake constantly, but it could not destroy it.

At the same time, the trebuchet behind Cai Yong also pushed forward, and hundreds of pounds of boulders were thrown up piece by piece, and they were continuously projected towards Song Shicheng, screaming again and again on the city, and the city wall was also smashed out of holes. If it weren't for the fact that the city wall has been renovated by Wen Chengfang and is now more than four zhang thick, even these few potholes are enough to make the city wall collapse.

Wen Chengfang looked at the battle situation in front of him, and the cold sweat on his forehead came down, he couldn't have imagined that this time the Song army, which he thought he could barely attack, would have such a big battle, and even such a huge siege engine that consumed power and money was pushed up, and it would take months to build such a big guy, to say the least, this is still in the case of abundant manpower, material and financial resources, which shows that the Great Song Emperor has never given up dealing with Yue Shao'an, with the bulletproof degree of this thing, it is obvious that the emperor suffered a big loss under the Song Shicheng last time, This is the time to make a bloody investment, it seems that he will not give up if he does not take Song Shicheng.

Wen Chengfang realized the seriousness of the problem, and while directing the catapult and artillery bombardment, he sent someone to invite Zhu Chongyi to come, because now it seems that this siege vehicle does not have a flaw, no matter how it attacks, it has no half effect, and the one who can create this kind of thing is undoubtedly Zhu Chongyi's mysterious master, and the one who can crack this thing is estimated to be the only one in the world.

While the siege vehicle was constantly approaching, Cai Yong did not let the other soldiers idle, the ladder and the Song army that hit the city gate were carried out simultaneously, although the two sides did not reach the final decisive battle, but the battle situation was extremely tragic, however, at this time, it was still Song Shicheng who took the initiative, and the bow and crossbow continued to shoot at the enemy army below, and the Song army suffered heavy casualties.

However, this is not the point, the point is that the siege vehicle is still advancing, and it is about to approach the city, if it is allowed to come over, the advantage of Song Shicheng will be gone, therefore, Wen Chengfang did not hesitate to attack the huge siege vehicle with all his might, but unfortunately it had little effect.

Just when Wen Chengfang was anxious, Zhu Chongyi came, the immature young man at the beginning, and now the handsome guy, has already become Yue Shaoan's right-hand man, and the figures who rushed on the horse were so high-spirited, but Wen Chengfang had no time to appreciate it, and when he saw Zhu Chongyi coming, he hurriedly stepped forward and pulled him to the top of the city, pointed to the huge siege vehicle, and said: "General Zhu, do you know this thing?" ”

Zhu Chongyi looked at it one by one, his face also changed slightly, and said: "I didn't expect the master to really create this thing, this was originally evolved from an ordinary siege vehicle, but there is a lot of knowledge in it, there are three floors inside, and none of them can accommodate nearly a thousand people......

Wen Chengfang listened to Zhu Chongyi's narration, although the story seemed to have merit, but he was in the mood to listen to the story at the moment, so he hurriedly interrupted Zhu Chongyi and said: "General Zhu, at this moment, let's not care how it came from, you see that there are iron plates in front of the body, we can't break it at all, if that thing comes forward, then it will be troublesome." Is there a way to crack it? If so, say so......"

Zhu Chong nodded, put the storytelling behind him, and said seriously: "Any instrument is man-made, and it is always easier to destroy than to manufacture, this thing seems to be indestructible, but it is actually very easy to break......"

Wen Chengfang heard it in his ears, was happy in his heart, and hurriedly asked: "Tell me quickly, how to break it?" ”

Zhu Chongyi: "The outside of this car is almost completely wrapped in iron armor, and the only thing that is not wrapped is the rear, but even if the rear is destroyed, it cannot be disintegrated, and it can only restrict movement." Therefore, if you want to break it, you still have to go inside, just put a fire from the main pole in the middle, and all the problems will be solved......"

"Inside, inside?" Wen Chengfang's eyes widened suddenly, and he asked for a long time, isn't this almost the same as not asking, breaking from the inside, if you can get inside, why do you still ask? Wen Chengfang was angry in his heart, but he couldn't attack, he turned his head suddenly, pointed his blade at the siege vehicle, roared, and said, "Hit, smash it for Lao Tzu—"

Zhu Chongyi saw that Wen Chengfang was so excited, scratched his head, and said, "There is really no better way, but this time, I brought some things, maybe it will be useful." ”

When Wen Chengfang heard this, he seemed to suddenly see a glimmer of light in the darkness, and hurriedly turned his head and asked eagerly, "What is it?" ”

"Huoji, Brother Yue told me some production methods, I thought about it carefully for a long time, and I still couldn't make the kind he said, but I still made a batch, although the power is not as big as the artillery, but it is more convenient to slack off......"

While the two were talking, the siege vehicle had already approached the front, and the Song army rushed down from it like crazy, and the bows and arrows on it were extremely dense, suppressing the attack of the defenders of Song Shicheng, and for a while, the defenders were defeated and retreated.

Wen Chengfang was really anxious, and said continuously: "General Zhu, General Zhu, let's not introduce the usage first, how much did you bring this thing you said, is it easy to operate?" ”

Zhu Chongyi: "Although it is not difficult to use the firecracker, it is definitely not good for soldiers who have not used it, so I brought two hundred people this time, these people are all trained and can be put into battle." ”

"Then what are you waiting for, get on them." Wen Chengfang urged Zhu Chong.

"No way!" Zhu Chongyi shook his head decisively.
