Hundreds of catapults fired stone bullets at the same time, the scene was extremely spectacular, hundreds of stone bullets flew in the air, drawing arcs in the air, and then roared and smashed into the city wall of Xindu, erupting into a huge impact sound, brick debris flew sideways, dust and smoke were filled, and the walls of the entire city wall were shaking incessantly.

This feeling of shaking the ground and shaking made the Jizhou army panic, and the shaking amplitude of the city wall had obviously exceeded their prediction, as if experiencing a strong earthquake, the city wall kept shaking, and everyone's legs also trembled, and their faces were as white as paper.

This is just the first round of attack by the catapult of the Bingzhou army, which has already caused such a terrifying result, and it is rumored that the city wall of Lecheng was knocked down by the catapult, which naturally makes the Jizhou soldiers of the defending army panic.

Lu Zhao also personally climbed to the head of the city to command, originally he came to boost morale, but countless stone bullets smashed down on the head and face, Lu Zhao's face suddenly became pale, and the power of the catapult of the Bingzhou army was indeed beyond Pinzhao's expectations, and he realized that the loss of Le Cheng was not an accident, if the catapult of the Bingzhou army continued to attack, even the city wall of Xindu would not be able to bear it!

After the infantry battalion experienced the battle of Lecheng, the skills of the catapult attack have been further improved, and when attacking Lecheng, the catapult adopted a flowering attack method, both attacking the city wall and attacking the city head, and some of the stone projectiles were too violent, and they were thrown directly into the city of Lecheng.

This multi-point flowering attack method can certainly cause more damage to the enemy, but it also wastes a lot of stone bullets, and finally relies on continuous attacks on the city wall, and smashes a hole more than ten zhang wide from the solid city wall to complete the final breakthrough.

After the battle, Yanghu summoned the officers of various departments to seriously summarize, not to say that everything was fine after the attack, but to sum up the gains and losses, find problems and rectify them through such a campaign.

Although it can cause a large number of casualties to the enemy, if the enemy takes the initiative to evacuate, the casualties will be reduced, and at most it can only destroy the defense facilities of the city.

Therefore, the attack of the catapult should still be mainly to destroy the city wall, supplemented by attacking the city head, and concentrate most of the bomb drop points in a certain section of the city wall, so as to effectively destroy the city wall in the shortest possible time, so as to achieve the ultimate goal of the attack.

After arriving in Xindu, before the war began, Yanghu had already personally surveyed, figured out the condition of the Xindu city wall, formulated a detailed attack plan, and communicated with Du Yu and Zhan Hong.

After all, after the shooting battalion and the left guard battalion were equipped with catapults, they had not really carried out siege operations, and they were still a little unfamiliar with the use of catapults, and Yanghu had enough experience after experiencing the battle of Lecheng, and now after he passed on these experiences to Du Pre and Zhanhong, he could also let them take fewer detours and make the catapults achieve the maximum attack effect as much as possible.

Therefore, when the eastern and western sides of the army attacked at the same time, the attack methods adopted were completely identical, and they all focused on the city wall of Xindu as the first attack target, and concentrated all their efforts to carry out a destructive continuous attack on a certain section of the city wall.

The blow to the city was an auxiliary means, and at most it played a role of intimidation, forcing the Jizhou army to panic and let more people evacuate the city wall.

The city wall of Xindu, when it was built, the cost of investment was much larger than that of ordinary county towns, not only did Xindu have two city walls, the outer wall and the inner wall, but also the height and thickness of the outer wall, the height and thickness of the city wall far exceeded the city wall of the county town such as Lecheng.

Therefore, the city wall of Xindu is not only tall but also more solid, if the state army adopts the method of attacking Lecheng to attack Xindu, if you want to destroy the city wall, I am afraid that it will not be possible without ten days and a half months.

But now the Bingzhou army has changed its attack strategy, focusing on destroying the city wall, and continuously bombarding the same section of the city wall, even if the city wall of Xindu is strong, it can't bear it!

The army of the state had a sufficient number of stone shells in stock, and from the very beginning of the firing showed no signs of stopping, and continued to attack the same area of the city wall, and the number of bullets dropped in this area was obviously much greater than in other places.

At first, the Jizhou army didn't feel anything unusual, but after some cracks appeared on the city, they realized the seriousness of the problem.

At first, these cracks were not very obvious, only the width of a finger, but as the state army continued to bombard, these cracks became wider and wider, the largest crack turned out to be a foot wide, unfathomable, where the cracks appeared, the city wall began to deform, and it was seriously tilted forward, and there was a risk of collapse at any time.

Someone immediately reported to Lu Zhao, and Lu Zhao also went to the area to check it in person, and sure enough, something was wrong, it was obvious that the attack of the catapult had damaged the structure of the wall, and if it was allowed to continue to attack like this, the city wall would likely collapse.

Lu Zhao's face changed suddenly, this was just the first day that the Bingzhou army began to attack, it caused so much damage to the city wall, it can be seen that the catapult used by the Bingzhou army is quite powerful, no wonder Lecheng City will be lost in two days, now seeing the power of the catapult of the Bingzhou army, the last bit of doubt in Lu Zhao's heart has disappeared, the catapult of the Bingzhou army, the power is really extraordinary, even the strong city wall, can not resist such an attack.

It stands to reason that Lu Zhao is still full of confidence in the plan to hold on to the city for half a month, because Xindu has two city walls and a garrison of 70,000 people, and he has every reason to believe that Xindu will be able to hold out until Sima Shi's reinforcements arrive.

But the situation that has emerged now makes Lu Zhao can't help but worry, and the state army's arrogant and unreasonable style of play makes him a little helpless, this is completely a crushing siege operation, and the state army launched an attack with all its might, but the Jizhou army has been passively beaten, and has no power to resist.

At the beginning, Lu Zhao had the intention of using trebuchets and bed crossbows to counterattack the catapult positions of the Bingzhou army, but in the end he found that their range could not reach the catapult phalanx of the Bingzhou army at all, and their counterattack could not be effective at all.
