As night fell, there was silence in the Tiger Prison Pass, and the Zheng soldiers were motionless and nervous, their eyes focused on the scouts who crawled to the ground and listened intently. Pen & Fun & Pavilion www.biquge.info

"The digging stopped." After the man heard it for a while, he raised his head and said to Zheng Qingzi.

Zi, who has been guarding the Tiger Prison for more than a month, breathed a sigh of relief, stroked his beard and smiled proudly: "It seems that these Jin people are finally dead, the foundation of the Tiger Prison City was paved by my father from the middle stone in the mountain, and it was impossible to dig it up with the manpower below, they probably broke their heads, dug up the tools, and returned in spite of the difficulties!" ”

Zi Pan is the son of the Feng family in the Seven Mu of the Jin Kingdom, and their branch was also ranked in the Jin Qing, but it has not been the turn of the Jin Dynasty for forty years. When the son-like father Feng Juan served as Zheng Guo's castle, when it was rebuilt into Gao City, Feng also realized that this place was extremely critical, and in order not to let the Jin Mourning Gongcheng Tiger Prison force Zheng Guo to submit to the repetition of the repetition, so the city was renovated, and it was suddenly renewed, and it was called the number one fortified city in this era, although it was small, but it was strong.

Although there are many Han soldiers outside the city, and Zheng Guo's main force is also contained in the east by Han Hu and Zheng Guo, as long as Zhao does not fully intervene, Zheng Guo can rely on his own strength to repel the enemy.

Seeing that the Han army no longer tried to continue digging the tunnel, Ziyan was relieved, but he still asked everyone to be vigilant in case something changed after the night.

He himself went back to sleep for a while, dreaming of Xinzheng's beautiful music, and the debauched taxi and the girl, which is what summer should be......

But after he had slept for a while, he was woken up in a hurry, and in a daze, he heard a noise and panic outside, and suddenly a spirit jumped up with his sword. When he went out, he found that it would be the deepest darkness before dawn before dawn came, so he reprimanded his soldiers, and then climbed the wall in the northwest corner again to look at the enemy camp.

Looking at it, his face became solemn.

"Is the Korean army planning to attack the city after dawn?" Hundreds of steps away, in front of countless black and oppressive camps, the Korean army lit torches and gathered one after another, and its momentum was so great that it was like a sea of fire that countless fireflies gathered together and turned into a sea of fire, with nearly 10,000 people!

Could it be that the general attack is tomorrow morning? A cold sweat broke out on his forehead, and while he ordered all the resting soldiers to go up the wall and prepare, especially the easily vulnerable corners of the city, he was also desperately thinking about how the enemy would attack.

Ladder ant attached? Flying stone siege?

At this moment, in the northwest corner of the city wall where he was, there was a strange movement.

"Did you hear anything?"

The soldiers looked at each other nervously, and then they all looked at the city walls.

Someone hurriedly ran to the dark room where the weapons and armor were stored under the city wall, only to feel that there was a faint noise under the feet of a foot thick, and something was gasping.

If you guessed correctly, below is the end of the tunnel dug by the Korean army, there is an enemy, this is already certain, but on second listen, the thing below does not look like a person, but like some kind of beast that has been cornered, at least dozens or hundreds can emit such a scale of screaming and gasping.

Zi's brows have been twisted into a pimple, the Korean army outside the city has been assembled, under the firelight, they are carrying all kinds of ladder planks, and countless faces are gloomy or dark, which makes Ziban even more confused, what are they waiting for? What exactly does the Han want to do under the city walls?

Tiger Prison Pass was first built by the Jin people and reinforced by Zheng Guo, although it was one of the best fortresses in Zheng State, but the defenders of the city were also helpless against the enemy from the underground.

At this moment, a sudden change occurred!

The shrill wheezing of those beasts became even more rapid and crazy! And......

"The ground is hot...... the soldiers who were sent to the dark room jumped up like ants falling on a hot pot, and white smoke was rising from the cracks in the stone foundation under their feet, and slowly became hot feet, and no one could stay on them for long, and they hurriedly reported the matter.

Are the enemy troops lighting a fire below? And then what? And can you expect the flames to burn down the walls? This kind of imagination is too ridiculous, Zi Pan doesn't think it's possible, but the more this happens, the more weird he feels, and today's Han Clan's behavior makes him feel extraordinary, something happened quietly without his knowledge.

"Leave the northwest corner ......" gave this order with his instinct for the approaching danger.

Just as the Zheng people began to retreat from the northwest corner one after another, the heat wave from the ground had begun to seep into the surface, and the flames had already burned dozens of paces of city walls......

Everyone was inexplicably frightened in the face of all this, and the moment they walked down the wall, the foundation of the northwest corner began to tremble......

Like a tired giant standing on it, the entire northwestern wall is shaking, as if you want to shake off the Zheng people who are still on it, along with the dust and moss that have covered it for decades, and you have to hold on to the female wall to stand firm.

This state of affairs lasted for nearly half a moment, and then, the corner tower began to sway like a drunken strong man, and then it fell to the ground with a bang! More than a dozen people were killed by the flying bricks and wooden stakes everywhere, and the northwest corner of the city, in full view of everyone, suddenly fell downwards and collapsed a big hole!

Zi watched this scene in amazement, watching the wall that was several feet high yesterday suddenly brittle as paper paste in front of him, and under the collapsed wall was a terrible sea of fire, the tunnel that Han had dug up: the charred corpse of Fei Yan, the sizzling hot grease, and the burnt wooden stakes......

……

"The wall is falling!" Unlike the stunned and desperate inside the city, there was a continuous cheer outside the city.

Outside the city, the Han soldiers had been waiting for half an hour, and the frost and dew of the early morning covered their hair buns and beards, and rolled down from their crests.

Everyone didn't sleep enough, they sat idly and waited for so long, they were all a little slack and dissatisfied, yawning all day, talking louder and louder, they didn't have the strict military discipline of Zhao Jun.

"Get up! Get up! The whip of the officer came and urged them to get up, and at that moment they witnessed a miracle: the northwest corner of the enemy's army, which they were directly opposing, collapsed with a bang! Even with the collapsed, there are dozens of steps of walls!

The Han soldier rubbed his eyes in disbelief, then passively moved forward, and the battle began, this time, the cowards in the city could not hide behind the strong walls and throw arrows and stones at them!

Relying on the numerical advantage alone, there is no suspense in this Chenggao offensive and defensive battle.

At the same time that the drums sounded and the Korean army launched an attack on Cheng Gao, who lacked a big mouth, with weapons, Lu Ban fell into a sound of praise and praise.

What kind of genius is incredible, the generals and craftsmen of the Han clan are full of praise, but Lu Ban laughs and is silent.

"It's just a simple siege method, so it's not surprising." It's not that he's modest, it's a fact.

Since the establishment of the Linzhang School Palace, Baigong, a lowly and humble group in the past, can even occupy a place in it, Lu Ban is their leader, when there is no task, he stays in the workshop in Yecheng, doing all kinds of experiments and inventions, turning his whimsical ideas into reality, although most of them ended in failure, but Zhao Wuxian encouraged him again: "Failure is the mother of success." ”

They also often went to the Yecheng Festival Hall to discuss with the military how to attack and defend the city, and sometimes Zhao Wuxian would come over to observe, and from time to time he would come up with a few amazing ideas.

After two or three years, Lu Ban's siege technique has been more systematic, they summed up the "Lin, hook, rush, ladder, moat, water, hole, sudden, hollow, ant, Xuanche" a total of 12 kinds of siege methods, although some of them only stay at the theoretical level, but as long as measures are adapted to local conditions, there is no helpless city in this world.

For example, this time, he used a combination of acupoint attack and fire attack, of course, it was also a trick that Zhao Wuxian once mentioned, as soon as he said it, Lu Ban immediately wrote it down, and conducted experiments, and the effect was ...... Amazing!

Lu Ban is a family of craftsmen, civil engineering is the ability to take care of the house, knowing that in this era, all the city walls are basically dug deep foundations first, and then paved with stone foundations and rammed earth walls.

If the foundation collapsed, there was no reason for the city wall above to survive, so Lu Ban first asked the Korean army to dig a tunnel, and as the excavation progressed, a large amount of wood was used to support the top of the tunnel. When it happened to be under the wall in the northwest corner of the city, it was widened slightly, and then a large amount of straw, grease, and coal were added, and finally a large amount of fat was driven into the tunnel, and then ignited, and in the narrow space, lard mixed with coal, straw and other flammable materials burned in large quantities, and all the wooden piles supporting the top of the tunnel were burned, and the air was violently expanded by the high temperature, and the foundation became crumbling, and finally the whole piece collapsed......

This method is troublesome, but it is also effective, now that Chenggao has been broken, the Korean army is shouting and screaming and pouring in, Zheng Guoren has become weak under the blow of the shock, but he still relies on several other city walls, fighting from sunrise to sunset, so that the Korean army has paid nearly a thousand casualties, and its commander is forced to the last corner tower with hundreds of remnants before asking for surrender.

"It's finally down!" After Duan Gui stepped into Cheng Gao, which was full of corpses and charred remains, he knelt on the ground and held the soil soaked with blood, howling and crying, attacking Cheng Gao, this was his strategy to Han Hu, Han Clan invested almost all the troops and food reserves for this purpose, and he was determined to win, once he failed, the blow to Han Clan would be quite large.

But the initial stage of the war did not go well, and Cheng Gao couldn't attack it for a long time, but this was when Han Hu attracted Zheng Guo's main force! For this reason, many people reported to Han Hu, saying that Duan Gui was not, saying that he would not lead the troops, and even attacked the strategy itself.

Duan Gui was also worried that he couldn't sleep at night, but Han Hu just sent a basket of letters back, with his name erased, but the content was all Han family's retainers and diners criticizing Duan Gui, and there were dozens of copies!

Han Hu aimed to show that he did not have the slightest doubt about Duan Gui, and at the same time he was beating him: If I can't take it anymore, I can't support public opinion, so I can only take you under the knife......

Now that it's done, how can Duan Gui not be happy? He bowed again in the direction where Han Hu was in the east and said, "The capture of Chenggao is not by my strength, but by the merit of the lord!" ”

At the end of the words, I heard someone snort coldly: "It seems that it is all because of the Han family's Jun Ming Chenxian, this can lay the tiger prison, so in this way, there is nothing wrong with me and Zhao Shangqing?" ”
