"Okay, Master Zhou has made a great contribution this time!" Soon this result was confirmed by the observers on the hot air balloon, stuffed into the bamboo tube and slid down the cable, and came to Li You's hands, Arubb's hard-built trebuchet lost more than half of the first wave of attacks, and the rest must not have had time to escape the next attack of the Jiazhou army.

"Thank you Your Majesty for your praise, I just acted according to His Majesty's orders, and I really don't dare to take credit." In order to improve the enthusiasm of the craftsmen, Li You and Gu Jiangzi discussed a set of craftsman level certification system, according to the level of the craftsman to give different treatment, status and honor, among which the master craftsman is second only to the level of the master craftsman, this level is now no second person except Gu Jiangzi, that is to say, Zhou Zhengxin is already one of the few craftsmen in the Jia Dynasty at a young age, and it is only a matter of time before he becomes a master craftsman.

"Since ancient siege warfare, the most difficult thing is to explore the layout and movement of the enemy army in the city, but with this thing, the movement of the enemy army in the city can be seen at a glance, and our army can specifically find the flaws of the enemy army to launch an attack, which is really convenient!" Shi Huaiyi is a well-read history book, and of course he can see the importance of hot air balloons to the war.

The development of the next battle was also as Shi Huaiyi expected, after destroying the trebuchets of the northern captives, the trebuchets of the Jiazhou army launched an attack on the most densely populated place of the enemy behind the city wall, and the northern soldiers suffered heavy injuries for a while, and Arubu had to order them to hide away for the time being to avoid further damage.

The reduction of the strength of the defense of the city just provided an opportunity for the Jiazhou army under the city, Li You immediately responded, Zhou Bofu led the siege infantry to set up a ladder, pushing the nest car, building car and other siege equipment towards the weakest defense of the city wall, artillery, fire and crossbow also increased the suppression of this section of the city wall, the raindrop-like projectiles pressed the defenders of the city almost unable to raise their heads, seeing that Zhou Bofu's soldiers and horses were about to arrive at the city, they had to raise their heads to counterattack.

At this time, the battle became more and more intense, and the way of transmitting the message on the hot air balloon was changed from throwing notes to flags, and several soldiers waved two small flags to quickly convey the movement of the city head to the eyes of the Jiazhou army in the agreed way.

"The enemy army is ready to increase troops, the direction is 251, the number is 1,000, and the trebuchet is ready to carry out a covering attack!" Targeted orders came from the Chinese army, and a herald quickly passed these orders to the corresponding responsible person, and then made a targeted attack on the enemy's reaction.

waited for Zhou Bofu to lead the people to attack the trench, but did not encounter decent resistance, and Chen Heng's engineer battalion was already ready to cross the trench, and the planks were put on top of the trench, and the infantry rushed over quickly without waiting for the planks to be stable; The engineer battalion was divided into two groups, one of which remained in place and quickly dug a gap in the trench, intending to drain the water in the moat completely; The other part pushed the highly defensive carts against the city walls.

The top of the sloping wooden cart was made of hardwood-clad iron, and the coercion at the top could remove the impact of the rolling stones, so that the wagon could last longer, and six or seven elite soldiers of the engineer battalion were working on the huge bricks of the city wall with all kinds of strange tools.

The sharp blade made of stainless steel stuffed into the gap between the wall tiles, and quickly scraped off the glutinous rice mortar that bonded the city wall bricks, and soon turned the surrounding area of a city brick into a gap, and then another soldier stepped forward and stuffed several iron rods with curved and forked steel tips at the front into the gap, and the rest of the soldiers held the end of the iron rod together and pried it hard, and the city brick gradually loosened and was removed by them.

The sappers quickly pulled off all the bricks of the city wall in front of them, revealing the solid rammed earth wall behind them, and the engineer battalion had already figured out a series of solutions, the pointed pickaxe was hard to chisel on the city wall, and when a few small pits were chiseled out, the soldiers with steel drills behind them quickly pounced, and aimed the drill tips at these small pits and began to drill quickly.

The rammed earth of the Jianbi rock became as fragile as tofu in front of the steel drills, and large chunks of rammed earth kept falling, and the sappers soon drilled several large holes deep into the walls at the bottom of the walls.

"Alright, the size is almost enough, you guys go back first! Beckon the surrounding soldiers to stay away. The sapper leader drove his comrades out one by one, while he and his deputy stuffed a huge powder bag into a deep hole, attached a fuse, and quickly ignited it.

Sneering sparks came out of the lead and quickly approached the gunpowder bag, and the two people fled from the wooden cart as if they were burned, and fled to the rear with all their strength, and while escaping, they also beckoned the Jiazhou army that fell behind to speed up.

In the distance, the musketeers on the nest cart also increased the frequency of their firing, in order to suppress the northern captives at the head of the city, so as to cover these people to get out of safety as soon as possible.

"Lie down!" The ignition boss counted mentally as he ran, and when he felt almost, one of them threw himself to the ground, shouting at his allies.

"Boom!" As soon as the soldiers reached the ground, they saw a huge roar erupt from the bottom of the city wall, and countless broken bricks and hard earth burst out in all directions along with the firelight; The northern defenders above felt the walls shake and fell to the ground.

Dragon City is worthy of being one of the few fortified cities in the world, even if it is deep into the city wall, the explosion did not directly blow up this section of the city wall, but only exploded a huge hole under the city wall, through which it seems that you can faintly see the city.

Such explosions continued to sound under the city wall, and when the Jiazhou army's offensive stopped today and slowly retreated, at least ten such holes appeared on the root of the city wall of Dragon City, and these holes were full of huge cracks, and the cracks extended to all sides, making Arub and the others feel shocked.

The tense battle is over for the time being, but Arub can't put his mind at ease, he can completely see that the Jiazhou army's attack today is only tentative, and they don't use all their strength at all, and even then they feel that they are gradually exhausted, and then look at the holes and cracks left by those terrible explosions, Arubu faintly feels that this dragon city does not seem to be as indestructible as he imagined.

Compared to Arub, the Jiazhou Army has a different mentality, and they have already seen that the fall of Dragon City is only a matter of time.
