Inside the wall, Xu Gai nodded with satisfaction, turned his head triumphantly to the side, and said to Xu Guiying, who was on the side with an excited smile on his face: "See, this crypt method is originally a siege weapon, used for defense, and it seems to be extremely powerful!" When the Sui army saw this vision, they must have been greatly demoralized, and we will definitely be able to defend it this time! ”

Xu Guiying's eyes flashed full of heroic energy, and asked curiously: "The law of this crypt is already there, and the failure of the Sui army's attack this time is inevitable, but I want to know now, how can you calculate and let the battering ram fall into it just a dozen steps outside the gate?" ”

Xu Gai smiled slightly and explained: "The ordinary rushing cars of the Sui army in the past few days are helpless against the big iron gate of our Liyang Cangcheng. And our walls are very high, and the dead bodies and corpses at the foot of the walls are uneven, and they attack the city with ladders, and it is difficult for them to rush to the top of the city, but our great iron gate is strong. However, in the past few days, it has been hit by the rushing cars of the Sui army one by one, and it has been damaged in many places, if it can use the cloud ladder to feint to attack the city, but send a large siege ram to smash the door, it should be the best choice. Sure enough, Sui Jiang did just that. ”

Xu Guiying nodded, and asked again: "Then what's the matter with your pit, can you calculate the weight of this rushing car of the Sui army, just let it fall into it entirely?" If it was just an ordinary trap, this battering ram would have fallen into it as soon as it was pushed over, and it would not have been able to fall in its entirety like it is now. Besides. Since the siege of the city by the Sui army, the siege has been endless day and night, how could you dig this big hole under the nose of the Sui army? ”

Xu Gai touched Xu Guiying's hair dotingly, and said with a smile: "That is for my father to dig a tunnel, from the inside of the city gate to prevent the Sui army from attacking the trench dug in the trench, around the city gate to dig outward, the method of attacking the city in the crypt is often to dig the tunnel to the foot of the city wall, and then prop up the wooden pillar, and wait until the siege of the city." If the wooden pillar is burned, the pillar will collapse and the city will collapse, and the entire city wall dozens of zhang wide can collapse at once, and the child used the same method this time. At a distance of more than ten steps outside the door, a large pit with a radius of four or five zhang was dug, and wooden pillars were propped up underneath, and ropes were tied to the pillars. Pull down the pillars, and you can trap the entire siege equipment of the Sui army, and this time, the child will not give them another chance to pull out the equipment! ”

Hearing this, Xu Guiying suddenly realized, admired the slender thumbs up, and praised: "So that's the case!" Ah, you're amazing! ”

As the Xu father and daughter talked and laughed, hundreds of Wei soldiers picked up the bows and arrows that fell to the ground, and the feather arrows were still pouring in the direction of the big pit.

The soldiers of the Sui army who climbed the city wall, heard the loud noise in the direction of the city gate, and turned their heads to look over, but they saw the huge siege ram of their side, which actually fell into the ground all of a sudden, and the remaining Sui army on the roof of the car was shot into hedgehogs by the archers of the Wei army, and they were shocked in their hearts, and they didn't know what magic the Wei army used to do this, the ancients were superstitious, and this time it made many Sui soldiers beat drums in their hearts, wondering if this Liyang Cangcheng was protected by ghosts and gods, otherwise how could it be under the attack of the invincible Xiaoguo army in the world, Can you still be as still as a mountain!?

Husband war, courage also! The smooth start of the Sui army was precisely the result of courage and confidence, which made the speed of the soldiers faster, the reaction faster, and even the strength of the muscles increased, but when they witnessed their own big killing weapon battering ram actually fell less than a dozen steps away from the door, these courage and confidence disappeared at once, even the speed of the climbers slowed down, and the shouts and cheers and drums behind them were even quieter, and they were almost inaudible.

The soldiers at the head of the city sang war songs in unison, and even under the command of their respective officers, they scolded rhythmically: "Yang Guang Yang Guang, the small life is not long, the Sui army and the Sui army, all killed!" ”

With the shouting and laughter of the Wei army, the arrows and stones at the head of the city poured down like raindrops, and the soldiers of the Sui army who became sluggish and weak because of their weak hearts and qi were smashed off the ladder one after another, and the armored body of more than 200 catties smashed into those companions who were holding the ladder below, and directly smashed some people to death and stunned.

Not only that, in the city wall of Liyang Cangcheng, those arm walls also stretched out spears, stabbing directly at the Sui army who climbed the ladder, the piercing power of the spear is far from being comparable to the bow and arrow, dozens of spears poked out, just the Sui army that was climbing the ladder on the opposite side, caught off guard, stabbed through, and the corpse fell like raindrops, and the steel forks at the head of the city also pushed the ladder on the city head directly backwards and overturned, for a while, hundreds of ladders that had been added to the city wall fell one after another, and none of the Sui army attacked the city!

In the front military formation of the Sui army, seeing the protrusion of the mutation, Laihu'er and Dugusheng opened their mouths in disbelief that were big enough to stuff an egg, and their eyes were wide open, staring at the direction of the city gate of Liyang Cangcheng, and even rubbed their eyes suspiciously, they couldn't believe it, how could this good rush suddenly disappear, how could the original good situation suddenly reverse!

Dugu Sheng's lips trembled slightly: "Big, handsome, this, what's going on!?" ”

Lai Hu'er's face suddenly became very ugly, he hooked his mouth, and said: "I'm afraid that this Xu Gai did something in the tunnel at the city gate, saw the timing of our rush to attack, and then took it!" ”

Dugu Sheng looked at the battlefield situation anxiously and said, "Dashuai, what should I do now?" This rush was cracked by the Wei army in this way, and it was a big blow to the psychology of the soldiers, should you withdraw and reorganize the attack!? ”

Hearing this, Lai Hu'er looked back at the direction of Yang Guang in the back, but he couldn't see Yang Guang's expression clearly, and he couldn't receive any instructions. Lai Hu'er looked at the situation that the city had fallen into the downwind, hesitated for a while, and then decisively ordered: "Mingjin, collect the troops!" ”

"Knock knock~!"

The melodious sound of gold instantly resounded throughout the audience, and the soldiers of the Xiaoguo army who were besieging the city heard the sound, as if they had been pardoned, breathed a sigh of relief, spread the girl, and fled one after another as if they had to run to the main formation.

"Mahler,!" And Zhang Daniu and other soldiers who were fighting in a bloody battle at the head of the city heard the sound of gold, and also knew that things could not be disobeyed, so they had to curse, throw off the oncoming Wei army, turn around and run, or go down the ladder, or fall directly into the city, and they all showed their magical powers, broke away from the battle, and retreated.
