Soldiers come to the world

The Han army suffered heavy losses in Cao Jun's counterattack. The catapults on the top of the mountain were completely destroyed, and the wooden platform built for moving the catapults was also destroyed by huge stones, which caused a serious setback for the Han army's attack on the high platform.

At night, the Han army piled up the earth mountain again, lengthened the road up the mountain to two miles, and made the slope gentler, so that the parts of the trebuchet could be directly transported to the top of the mountain by bullock carts, and a two-foot-high barrier was built on the top of the mountain. Flint wall, prepare a lot of fire extinguishing lime.

At dawn, Cao Jun launched a fire attack on the Han army's earth mountain again, but this time the effect of the fire attack was much weaker. Most of the kerosene was intercepted by the stone wall. The soldiers quickly buried the spilled kerosene with lime.

At this time, more than [-] assembled Han army trebuchets showed their power again, and huge boulders and fire oil tanks shot at the mounds in the city, causing the mounds in the city to be engulfed by fire again.

Two days later, Cao Jun took advantage of the opportunity of the Han army to replace the trebuchets, took the initiative again, destroyed the stone wall, and forced the Han army to withdraw from the earth mountain.

The battle between the Han army and the Cao army for Lingao continued, but at this time, the Cao army's patrolling guards on the west city discovered a slight anomaly.

In the early morning, Zhang Liao got the news and hurried to the west city. At this time, the deputy general Zang Ba had arrived first and was staring at the riverbed with all his attention.

As soon as Zang Ba turned his head, he saw the coach Zhang Liao walking forward under the guard of more than [-] personal soldiers. He quickly clasped his fists and saluted, "See the coach!"

Zhang Liao nodded, and then asked, "I heard that something abnormal was found in the riverbed. What's going on?"

"Look, General!"

Zang Ba pointed to a low-lying tunnel with a radius of several zhang in the riverbed a hundred steps away, and said, "Yesterday it was still flat, but today it's sunken."

"Are you sure?" Zhang Liao frowned and asked.

A patrol chief stepped forward to salute and said: "To the commander, I am absolutely sure that I saw it with my own eyes yesterday. Yesterday there was a flat ground, and there was a huge stone stained red with blood, but today the huge stone is still there, but the flat ground is still there." But it turned into a depression, and the humble official felt that something was wrong, so he reported it to the higher authorities."

Zhang Liao stared at the low-lying place, his eyes flickered, and he was thoughtful. Next to him, Zang Ba cautiously asked, "Wen Yuan, is this the Han army digging a tunnel?"

Zhang Liao nodded. There is indeed a possibility. The land in the riverbed has been soaked by the river water for a long time, and the soil has become very soft. If there is a hole below, it will easily collapse. Know, then bury dozens of large tanks under the city wall, listen carefully to the enemy's movements, and report to me at any time."

"Follow the order!"

Zang Ba turned and hurried away, while Zhang Liao carefully observed the low-lying place in the distance for a while. He couldn't help but feel a little confused. Except for the first day when the Han army dispatched tens of thousands of troops to storm the city, there has never been such a large-scale attack since then. Therefore, if the Han army is really eager to take Hefei, they should continue to attack Hefei City uninterruptedly. As long as Liu Jing is willing to pay the price, Hefei City will be able to take it sooner or later.

However, the Han army changed its offensive method and began to attack the city in a tricky way. Although this method did not cause many casualties, the effect would not be very good. Could it be that the Han army wanted to fight a long-term siege?

Zhang Liao has been fighting the Han army for more than ten years. He knows that Liu Jing is absolutely extraordinary. Every strategic decision of his has a far-reaching purpose. Judging from the fact that Liu Jing wiped out the Jiangdong navy at any cost, he will never care about attacking. The casualties of soldiers, so what is the purpose of Liu Jing's tricky battle?

As Cao Jun discovered, the Han army was indeed digging tunnels, but the purpose of digging tunnels was not to enter the city through the tunnels, but to hollow out the soil under the city walls. It brought great influence, and made the soil under the city of Hefei generally loose, which brought adverse effects to the city wall of Hefei.

According to Fazheng's plan, they can dig dozens of tunnels under the city wall, directly under the city wall, first support it with wooden piles, and then burn the wooden piles with fire. Without the support of the soil under the city, the city wall will collapse. This is the way to attack the city. A classic strategy.

Liu Jing adopted Fazheng's plan and ordered thousands of soldiers to start digging tunnels 27 steps away from the west city. A total of [-] tunnels were dug. They have been digging for three days, and the longest tunnels are about to reach the city wall.

However, an accident was discovered in one of the tunnels. The soil on the river bed was not completely dry, and more than a dozen cavities were formed in the soil. The excavation of the tunnel caused the cavities to burst, and the surface sank, forming a depression about Zhang Xu wide.

It was this accident that made Cao Jun at the head of the city discover the Han army's intentions. At this time, Cao Jun buried more than 100 large water tanks under the city wall, and Cao Jun soldiers were listening carefully to the movement underground.

"General Zang, is there any movement here?"

A soldier was the first to hear the underground movement, Zang Ba hurried forward, put his ear on the water tank and listened carefully, and he really heard the slight sound of digging underground, as if someone was talking.

Zang Ba couldn't help being startled. If he could hear voices, it meant that the Han army was not far away from the city wall, and they were probably under the city wall. At this time, more than a dozen soldiers heard the movement underground. Realizing that the problem was serious, he immediately sent someone to report to coach Zhang Liao.

Not long after, Zhang Liao came in a hurry. He listened carefully to each water tank, and quickly judged that there were thirteen tunnels, or there were more than that, and these were just the tunnels close to the city wall.

Zhang Liao picked up a branch, drew a simple map of the distribution of tunnels on the ground, and said to Zang Ba: "Have you noticed that the distribution of the Han army's tunnels is more than forty feet wide. Generally, the more tunnels you dig, the easier it is to be discovered. It's impossible for Liu Jing not to know, but he has dug more than a dozen tunnels, what is the general's purpose?"

Zang Ba pondered for a while and said, "If these dozens of tunnels collapse at the same time, it will have a great impact on the city wall, and even cause a section of the city wall to collapse. Could it be that the Han army wants to sink the city?"

Zhang Liao nodded, "I think so too. With so many defenders in the city, it is meaningless to enter the city through tunnels. Only when the city wall collapses can the Han army invade the city on a large scale. Liu Jing must have this purpose."

Zang Ba sneered and said, "In that case, let the humble officials deal with them."

There is a long strip of woods 27 steps away from the west city. Under the cover of the woods, the Han army dug [-] tunnels on the ground. Hundreds of Han soldiers used earth blowers to continuously blow air into the tunnel.

Each tunnel is three feet wide and four feet high. Soldiers cannot stand up and can only walk forward in a half-squat. However, most of the soldiers involved in the excavation are short in stature and can turn around in the tunnel.

Fazheng was a little nervous. In the early morning, some scouts found Cao Jun gathered at the top of the city. Many generals of Cao Jun stood on the top of the city and looked towards this side. It feels that maybe Cao Jun discovered that they were digging a tunnel.

Fazheng hesitated in his heart. There were two thousand soldiers in the tunnel. Once they all died in the tunnel, he could not explain to His Highness the King of Han. Should he withdraw the soldiers first and wait for two days to observe.

When he was thinking about it, there was a terrified shout in the tunnel, and countless soldiers rushed out of the tunnel. Fazheng was shocked and hurried forward and asked, "What happened?"

"Military Master, there is poisonous smoke in the tunnel!"

Fazheng stomped his feet anxiously, "Send the signal quickly and let all the soldiers withdraw!"

There was a rush of bells ringing in the tunnels, which was an order to retreat, but without the bell ringing, the Han soldiers in the 27 tunnels had rushed out one after another. They coughed desperately, and many of them fell to the ground and fainted.

After a while, billowing black smoke began to emerge from the tunnel, filled with a strong smell of sulfur and arsenic. This is the dense smoke produced by the burning of coal oil, sulfur and arsenic, which is extremely toxic.

Fazheng felt chills in his heart. He saw that there were still many soldiers who hadn't withdrawn. At this moment, a general stepped forward and said in a low voice, "Military division, there are still more than 500 brothers who have not been able to withdraw."

Fazheng couldn't help but let out a long sigh. He knew in his heart that these 500 people would not survive. This is the real plan. Once the enemy finds out, it will be easy to crack. He doesn't know which part of himself is wrong. Maybe Cao Jun He has his own precautions, but the matter has come to this point, he can only plead guilty to the King of Han

In the big tent, Liu Jing shook his head after listening to Fazheng's report, and said, "Winning or losing is a common matter in military affairs, and the military advisor didn't make any mistakes, and Zhang Liao is a famous general of Cao Wei, so it's normal for him to see through it, so there is no need for the military advisor to blame himself." .”

Liu Jing's reassurance made Fazheng feel a little better, but his plan failed, which made him feel uneasy all the time. At this time, Pang Tong smiled and said: "Actually, it is not necessary to dig tunnels to collapse Cao Jun's city. I have a There is a way, maybe it will work.”

Although Liu Jing didn't blame Fazheng for the failure of the tunnel, it didn't mean he didn't care. He was defeated or seen through by Zhang Liao several times in a row, which really annoyed Liu Jing. Find out what's really going on in his heart.

Liu Jing asked quietly, "What can Master Pang do?"

Pang Tong stepped forward to salute, and said with a smile: "It was quite hot yesterday, and the soldiers brought me a cup of deep well water. The well water was really icy cold. what consequences"

Before Pang Tong could finish speaking, Huang Zhong and Gan Ning clapped their hands together and applauded. Huang Zhong said to Liu Jing with a smile: "Mr. Pang's method is really good. This method is used in quarrying in my hometown. You can try it."

Liu Jing pondered for a moment and said, "Try it in Beicheng tonight!"

The battle between the two earth mountains inside and outside the North City has gradually reached a balance. Both sides have built firewalls and prepared a large amount of fire extinguishing lime. It is difficult to see the scene of burning the mountain again. Since the two earth mountains are in a confrontation, neither side can attack and defend the North City. war.

At one watch, fifty heavy-duty catapults gradually approached the city wall, and stopped 350 steps away. Safety.

With the order of the veteran Huang Zhong, fifty heavy-duty trebuchets creaked and opened their throwing poles, and fifty clay pots filled with kerosene rose into the air and shot at the city wall. Clay pots hit the city wall, and kerosene flowed all over the outer wall.

At this time, a Han soldier hiding in the riverbed fired hundreds of rockets. The rockets ignited the kerosene on the wall, and the flames spread rapidly. The flames burned blazingly. .

The fire oil clay pots of the Han army continued to shoot, and the fire on the city wall became more and more intense. The Han army had already thrown thousands of barrels of fire oil, and the entire northern city became a city of red flames. The soldiers of the Cao army retreated to the distance, trembling Watching the Han army burning the city in horror.

Pang Tong watched the changes of the city wall below from the earth hill. He knew that the quarrying procedures in the quarry are exactly the same today. First burn the city wall with fire, and then pour it with ice water, and all the bricks and stones of the city wall will burst. Catapults hit the city walls with huge boulders, and the walls will all collapse.

He found that the bricks on the wall had been burnt to a crimson color, like a hearth that had lasted for three or nine days, and the sound of cracking bricks and stones was heard continuously. He knew that the fire was enough, so Pang Tong immediately said to a soldier, "Go and tell General Huang, Change to water attack!"

The soldiers rushed down the mountain, waving their hands and shouting from a distance: "Old general, the military adviser said that it will be a water attack!"

Huang Zhong also knew that the time had come, and immediately ordered: "Change to water attack!"

The Han army had already filled thousands of large pottery pots with ice-cold deep well water, sealed the mouths of the pots with soil, and put them in iron pockets of catapults. Following Huang Zhong's order, fifty pots filled with bone-piercing ice The clay pot of water rose into the air and smashed towards the city wall that had already been burned red.
