Early in the morning of the 11th, the 40,000 soldiers of the Zhou army went to the city again, and divided the troops to start a siege around the city, only the trebuchet outside the west city gate fired for another half an hour, and then the Zhou army outside the four gates sent 4,000 crossbowmen to the city 120 steps to throw arrows in a long formation, and 3,000 infantry held high the shield to defend, covering the miners and stonemasons to dig the solid soil at the foot of the city wall under the city. Pen, fun, and www.biquge.info

When Li Yiyin heard about it, he climbed the pier of the north city wall under the strict escort of hundreds of personal soldiers, held on to the battlements and looked down, and saw that the Zhou army threw a rain of arrows every once in a while, which made the defenders dare not approach the outer wall battlements at all.

At the foot of the city wall, in the middle of both sides of the city gate, there were thousands of soldiers holding large shields to cover, and the soldiers digging were no more than a thousand, and they used hammers, steel drills, etc. to dig holes diagonally down the base of the wall, and the soldiers behind were driving the wagons back and forth to transport the earth.

"Are they trying to dig a tunnel?" Because it was too dangerous at the head of the west city, Li Guangrui was also watching from the head of the city here, and he was a little surprised when he saw this.

"Impossible! Zhang Tu is not so stupid...... I think they want to divert water from the Hongliu River to irrigate the city, but now is the dry season......" Li Yiyin himself is also unpredictable, and he can't figure out Zhou Jun's intentions at all, but the current situation is very simple, what Zhou Jun is doing must be something that is not conducive to the defense of the city.

Li Guangrui naturally thought of it, so he opened his mouth and suggested: "Father! The child led the horse army to attack and disturb, and the head of the city could also collect and throw stone bombs to throw down, so that the Zhou army could not destroy the city defense. ”

"Just go out with three thousand horses and see what they want to do." Li Yiyin felt a strong uneasiness in his heart, Yelu Tart Lie should have arrived in Liangu County outside the Great Wall of Fuzhou at this time, and it would take four days to go south, it is said that it is very easy to defend the city of Xiazhou for four days, but the performance of the Zhou army is too certain, it is just a stone projectile, and there is no even a tentative attack on the city.

Li Guangrui quickly went down to the city to order 3,000 cavalry, considering that outside the west city was where the Zhou army's marshal banner was located, and the troops were much stronger, he took advantage of the Zhou army's rangers to go away, Li Guangrui led his troops out of the east gate to form a little team, and then killed the Zhou army's crossbowmen along the flat ground outside the moat.

But the Zhou army also discovered that the main force of the horse army was taken away by Hao Tianying, and the rest were scouts, and only the Chinese army had 1,000 heavy cavalry left, which could not be intercepted quickly, but there were 2,000 crossbowmen behind each excavation team, which was not vegetarian. As soon as he saw that Xia Suijun actually went out of the city, he quickly changed the vertical column to a horizontal column, and the three rows of crossbowmen leveled the crossbow machine, and the cold and shining arrows made Li Guangrui frightened, but in order to find out the truth and truth, he still rushed forward.

As soon as he approached one hundred and sixty paces, he ushered in a rain of arrows and overturned more than 100 horsemen, and Li Guangrui did not dare to rush forward again after suffering a great loss, so he turned around on the spot and killed the chariots and horses who were carrying earth. When those soldiers saw Xia Suijun coming, they quickly removed the wheels from their horses and ran away on their horses.

Li Guangrui caught up with him and ordered the soldiers to dismount and overturn a carriage, and saw that most of the floating soil pulled on it was hard blocks, as well as complete city bricks and stone strips with relief patterns, and he was suddenly a little frightened. But there was no time to look more, the Zhou army was advancing in a wait-and-see formation three or four miles away, although there were only a few thousand people, Li Guangrui did not dare to fight hard, and the rain of arrows shot by those strong crossbows was too dense.

Li Guangrui turned around and turned outside the north city wall, the same is true, and at this time, the Zhou army ranger scouts also caught up and released arrows, Li Guangrui was afraid of being dragged and did not dare to stay, so he galloped around the city and went back to report, Li Yiyin summoned the eight patriarchs of the party to discuss, everyone was at a loss, and couldn't think of any way.

Seeing that Xia Suijun dared to go out of the city to attack and disturb, Zhang Yue sent scouts north to Wushui that afternoon, recalled Yan Chengwang's 4,000 horsemen, and when he came back, he could directly cross the river and go south for thirty miles, without having to detour, so in the next two days, as soon as Xia Suijun left the city, the Zhou army's horse team quickly attacked, making Xia Suijun helpless.

Li Yiyin also went to the city every day to supervise the battle, and ordered the soldiers to throw rolling wood and stones to destroy the Zhou army's engineering degree, but the Zhou soldiers raised the big shield and assembled it and shrunk it into a big turtle shell, causing limited casualties, and there was a fresh force to fill it every day, which was useless.

Seeing that every day passed, the loess mound in the distance was getting higher and higher, and the big hole at the foot of the city wall was digging deeper and deeper, Li Yiyin still didn't understand the purpose of Zhou Jun, and the panic in his heart became stronger and stronger, he had already realized that when Zhou Jun was completed, something big would happen, but he couldn't guess it.

After 3,000 miners and more than 20,000 soldiers who are good at quarrying excavated in batches and fixed points, and the one-stop assembly line operation was finally completed in the afternoon of the 13th.

After many failed sorties, Xia Suijun no longer went out of the city, Zhang Yue took three hundred personal soldiers to the city fearlessly, went to the eight wall foot explosion points to personally inspect and accept, and after confirming that it was correct, he returned to the camp on horseback, leaving four regiments and eight battalions of horse soldiers to go to various explosion points to guard the lead, and then fled after ignition.

When the infantry of the whole army assembled and retreated westward to twenty miles away, the sky was already a little dark, and Zhang Yue was a little worried about whether the soldiers and war horses would be deafening at the moment of the explosion, so he ordered each soldier to cut off two small pieces of his robe, pinch them into a ball and stuff them into his ears, and then all lay on his stomach.

Suddenly, a large area of the field was densely packed, and the soldiers looked at each other, all of them were a little inexplicable. The senior officers knew a little, but they didn't know too much, and they were too troubled to deal with the inquiries of the junior officers.

The retreat of the Zhou army was not a matter of a while, such a big movement, of course Li Yiyin heard about it, rushed to the city to watch, and saw that only the Zhou army scouts and small-scale horse teams were still around the outskirts of the city, and he didn't know what to wait for. The great hole that had been dug before was now filled, and strangely three or four long white ropes were buried, which stretched all the way to the front of the waiting caravan.

"Yelu Tart Lie will arrive tomorrow, and the Zhou army will retreat at this time, there must be some result!" Li Yiyin's face was like ashes, and he muttered, he felt that his head was not enough, and he couldn't figure out what was going to happen, but with his decades of life experience, he seemed to feel that death was approaching little by little.

"What can be done? The Zhou army actually retreated, or the child would go out of the city again to take a look......" Li Guangrui said inexplicably.

"Nope! No! You're leaving...... With Jiyun, Guangyuan, Guangxian, and Guangxin, as well as the children of the heads of the eight families, they must not fall in love with the war when they ride out of the city, and go to the Liao army camp. Although you are defeated today, with the children of these patriarchs in hand, you can come back and make a comeback in the future, do you understand? Li Yiyin suddenly turned his head and looked at his eldest son with a gentle face, but his tone was unquestionable.

"Father! At this time, how can the child go, the child wants to tide over the hardships with his father...... "Seeing that his father seemed to have the intention of entrusting the future, Li Guangrui thought that the matter had not reached that point at all, and he did not want to go to Liaoying now.

"You must do as I say, let's go! Let's go! Li Yiyin's eyes roared sharply, with a commanding tone.

"Father, handsome ......" Li Guangrui shouted a little reluctantly, but for so many years, unless his father intended to tolerate it, he never dared to disobey his father's orders, and bowed solemnly at the moment, turned around and strode down the city, and quickly went to prepare.

A moment later, the north gate suddenly opened, and Li Guangrui led a team of 3,000 horses to gallop out, seeing that the Zhou army horse team in the distance was still there, and he had no intention of fighting at this time, so he fled directly to the north.

"Look! There are birds out of the cage! Fifty horsemen were sent out to inform General Hao to intercept them. In addition, go to someone to see if the main force is in place, and you can't wait any longer. An officer of the Zhenyuan Army saw it from a distance and gave the order in a hurried tone. Although they were ordered to carry out the mission, they had only heard of gunpowder, but they had never seen the power of this thing.

The reconnaissance rode horses and galloped away, and after a while, they came back and reported: "The commander has an order!" It's starting to get dark, and it's time to start a fire! ”

When the deputy commander next to him heard this, he immediately took out the fire fold and lit a torch soaked in fire oil, and lit three leads one by one.

"What to see, what to see...... Hurry up, hurry up, go away! The soldiers all stared wide-eyed as they watched the three fiery snakes running into the distance at a speed visible to the naked eye, unaware of the danger. The two commanders and the battalion Yuhou also knew nothing, but the order from the higher authorities said that after lighting the fire, they should run as quickly as possible, and if they didn't want to fly into the sky, they should run as fast as they could.

Drive...... Drive...... Several teams of horses galloped wildly and gradually converged in the west of the city, and quickly disappeared into the night. Li Yiyin was still standing at the head of the city, and he wanted to see what Zhou Jun wanted to do. Seeing the three fire snakes outside the north city wall swimming quickly to the foot of the wall, they were silent for a moment.

However, in the next moment, the rapid wriggling and drumming at the foot of the city wall suddenly erupted into a sky-high fire, and the continuous roar of the mountains and tsunamis came from the city. Li Yiyin felt that his mind was hot, his eyes were full of stars, and then the whole person flew high, and his consciousness was uncontrollably blurred.

Eight loud muffled noises spread far away in the wilderness, and if it was daytime, one could even see a huge mushroom cloud rising in the distant sky, but now it was dusk and it was dark, and only the fire flickered in the sky, followed by a loud noise, and then the echo continued to fade away, and gradually fell silent.

Twenty miles away, of course, it was safe and sound, but soon the clanging sound continued, and the tens of thousands of soldiers lying on the ground thought that it was hail, but soon someone found that what fell from the air were clods of soil, small gravel grains, one by one in shock, buzzing and whispering, but they were surprised to find that the ears were still roaring, and they couldn't hear what the other party was saying at all, and they only saw that their mouths were opening and closing.
