Seeing that Zhao Xun did not attack the city for four consecutive days, in addition to letting the people of the Yan Dynasty continue to dig tunnels, that is, last night, people moved the crossbow machine and trebuchet into the tunnel. In addition, that is, the soldiers are training, and Zhao Xun is cultivating. Zhang Qianhe and Zhang Yu couldn't help asking: "General, why don't you see the siege?" ”

Zhao Xun smiled: "I thought you wouldn't ask, I'll see tonight." ”

"The general is attacking the city tonight?" The sides asked.

Zhao Xun smiled indifferently and did not speak.

Before I knew it, it was night again, it was the night of the fifth day, and Yi Lou Weiyang and Yang Qi were patrolling the city tower of Beicheng with their hearts, staring at the military camp of the Xiaoguo Army with shining eyes. The Xiaoguo outside the city, as in the previous days, did not move at all, and even seemed quieter, except for those dense trenches, as if they did not feel their existence, only whistling flags fluttering back and forth in the sky.

The night was so quiet, so quiet that it was highly unsettling. Compared to yesterday, tonight is quieter, and the silence makes people feel terrible.

"Chirp!"

Suddenly, the crossbow machines of the Xiaoguo army began to be launched, and the large crossbow machines hidden in the trenches came out one after another, and launched an attack on the back of the three-zhang high Liao Tunnel City. Huge crossbow arrows shot at the top of the city, making a crackling sound and splashing fire. After the Liaodong army at the head of the city was taken aback, they instinctively crouched down to avoid the enemy's arrows, and only a few observation posts still held out between the battlements.

"Huhuhu......"

"The trebuchet is the trebuchet of the Xiaoguo Army! Avoid! A soldier roared bitterly.

The trebuchets of the Xiaoguo Army also began to work, these trebuchets were also hidden in the trenches, and they could hardly be seen on the walls of Liao Tunnel City, but the stone bullets they fired, swirled in the sky, and then fell fiercely.

"Boom ......"

Stone projectiles kept falling, making a deafening sound behind the walls. Many stone projectiles flew over the walls and flew down behind the city.

In the city near the city wall, there are not many residents, and not many houses are intact, which is still the effect of the Liaodong army when it attacked half a month ago. Now no matter how many stone bullets fall, the impact on the Liaodong Army is not great.

Sometimes, stone bullets jump up in the streets, making very foul sounds, unusually harsh.

At this moment, under the cover of crossbow arrows and stone bullets, more than a dozen Xiaoguo troops jumped up from the trench. An attack was launched towards the north gate.

Yi Lou Weiyang and Yang Qi were surprised, could it be that Zhao Xun actually wanted to attack the city at night? General sieges, except for necessary and surprise raids, are rarely carried out at night.

But if you look closely, you find that these attacking soldiers of the Xiaoguo Army are neither carrying bamboo ladders, nor pushing arrow towers, nor carrying heavy sassellars, they seem to be each holding a large wooden barrel, and quickly approaching the north gate. These Xiaoguo soldiers, who didn't even have weapons, rushed forward with such a wooden barrel in their arms, and if they hadn't seen it with their own eyes, they would have thought they were crazy.

Although they didn't know what these people were going to do, both Yi Lou Weiyang and Yang Qi felt bad.

"Fight back! Fight back! ”

"Woo Woo ......"

Because the enemy was already very close to the city wall, it was difficult for the crossbow machine to be adjusted to such a low angle, and the archers could only be counterattacked with archers, and the archers of the Xiaoguo army gathered behind the city wall. Shoot the arrow into the sky and let it fall freely. The arrows kept falling, and the advancing soldiers of Xiaoguo fell from time to time, and the barrel also slipped to the side, but then it was picked up by the soldiers who jumped out of the trench and continued to rush to the city gate. Then the soldiers put the wooden piles neatly under the city gate, and they departed quickly.

"Cover with a giant shield!"

Seeing that the casualties were not small, Zhang Meng, who was in charge of the forward and eager to take revenge, said sharply.

Immediately afterwards, more than a dozen large steel shields were lifted, and the lower part was lifted with a long and special hook ring, which would be lifted together by the soldiers to cover the others to transport these special wooden barrels.

The Liaodong soldiers at the head of the city all thought it was strange, these Xiaoguo troops did not use sassalwood, what would they do under the city gate?

It took more than two hours for the soldiers of the Xiaoguo Army to slowly reduce the transportation. And the summer day dawns early, and at this moment, a bright light has appeared in the eastern sky, shining on the entire earth.

What is the Fruit Army doing? Not only was the Liaodong Army on the city wall puzzled, but Zhang Qian and Zhang Yu of the rear army were also puzzled. How can there be such a siege, the middle of the night has passed like this, let's talk about a raid, it's not.

"This is all the results of the past few days, four days in Changhe City, another five days here, and something that takes ten days, it will definitely produce results." Zhao Xun looked at the thickened wooden barrel placed under the gate of Liao Tunnel City, and said secretly.

In addition to the black powder inside, the outer rows of wooden barrels are completely filled with earth, and the other party strengthens the explosive power in addition to the gunpowder, and gathers its power.

"Hu Xiang, it's up to you!"

Zhao Xun, who also rushed to the trench, slowly said to Hu Xiang beside him, he was responsible for twisting the lead and ignition. Hu Xiang silently recalled the drills of the past few days and recalled various steps.

After hearing Zhao Xun's order, Hu Xiang responded to the order, drilled along the trench, and drilled until the very end, only to see the opportunity to jump up.

Seeing that someone was dispatching, the archers of the Liaodong Army on the city wall naturally attacked immediately. The arrows kept falling around him, but Hu Xiang, who only had a dagger and a small round shield, was very fast and swift, he ran in a straight line for a while, curved forward for a while, stood up for a while, lay down for a while, and rolled forward again for a while. In strict accordance with the training syllabus of Zhao Xun's personal guard battalion, most of those arrows were very close to him, but they never hit him, and a small part was separated by his round shield and the dagger in his hand.

Soon after, Hu Xiang finally rushed to the north gate. In the city gate cave of the north gate, there have been a full two hundred wooden barrels, all of which are filled with black gunpowder, Hu Xiang carefully inspected, so according to the training method, installed the fuse, entwined it, pulled it outside, lit the fuse, and immediately ran away.

"Puff puff!"

The arrows behind him kept flying, closely following Hu Xiang's footsteps, and the arrows shot into the dirt, splashing pieces of dust. After a while, I don't know if it was because of the completion of the work, Hu Xiang became more agile, and made a successful tiger leap and plunged into the trench in front.

"Lord, it's done!"

Hu Xiang said softly with a sigh of relief.

"Well done!"

Under the North City Gate, the long fuse was burning quietly, but the Liaodong Army above couldn't see it, and was still releasing arrows blankly, but the Xiaoguo Army, which was not a starter at the beginning, seemed to have all disappeared at this moment.

Of course, they didn't really disappear, but they were all crowded in the trenches, their heads bowed. As if waiting for something. The large crossbow and trebuchet also stopped working, and the operators also squatted on the ground, holding their heads, in a very strange posture.

The entire battlefield was suddenly silent, and the silence was terrifying.

"What is this doing?" Seeing that the soldiers around him also covered their ears, Zhang Qian couldn't help asking.

"Two adults, brothers, do the same! The divine thunder is about to appear. In the rear army, the captain who followed the two and their guards said to the two.

Although Zhang Qian and Zhang Yu didn't believe it, when they saw that all the soldiers were like this, they also felt that something was wrong, and they quickly covered their ears. And among the guards behind the two, some people disagreed.

"Even thunder is afraid of this, and it is still elite?" A guard behind Zhang Qian whispered.

Captain Xiaoguo shook his head and did not speak.

Yi Lou Weiyang and Yang Qi on the north city, seeing the sudden tranquility of the battlefield, instinctively felt that something was wrong, so they came to the top of the city gate and looked down, but they didn't find anything worth paying special attention to. The results achieved by the archers of the Liaodong Army can simply be ignored, such a large open field, except for the arrows in one place, there is nothing left.

"What does it smell like? Does the right general smell it?"

Elo Weiyang asked suddenly.

The smell of the fuse burning has drifted to the castle tower, and the smell is a little pungent.

"Weird smell, I don't know what ......"

Yang Qibei snorted, he also felt that this smell was very pungent, but it was not a familiar smell to him, faintly, he felt a bit like the smell of sulfur...... Brimstone?

How can there be sulfur?

When he was surprised, suddenly an earth-shattering loud noise lifted both of them into the air, and then there was darkness in front of them, and they didn't know anything.

More than 100 special earth-shattering thunderbolts exploded, not to mention the front, Zhang Qian and Zhang Yu of the rear army both felt a shock to the ground under their feet, and after a while, they fell all over the ground with mud and debris.

And the few people behind Zhang Qian who didn't cover their ears exclaimed, and they felt a buzzing sound in their ears, like a swarm of flies flying near their ears.

"Thor reincarnated?" Zhang Qian opened his mouth wide and exclaimed.

"That's amazing, isn't it?" Zhang Yu also exclaimed.

The whole earth seemed to be overturned, and the soldiers of the Xiaoguo Army in the trench felt that the whole earth was trembling under their feet, and the dust that kept falling covered them all. People farther away could clearly see that a dazzling fire lit up the sky over the entire Liao Tunnel City. After a violent explosion, the entire city wall was near the north gate. They all collapsed, and the north gate disappeared completely. There is only a gap of a few tens of zhang wide, and the broken city wall forms a huge slope.
