The Yellow Turban Army did not leave the city, and Lu Zhi had no choice.

The city wall was erected over there, and it was full of yellow turban soldiers, condescending, the Han army's siege was blocked, and it was impossible to use the ladder to climb the wall, it was purely looking for death, and Lu Zhi did not give that order at all.

Lu Zhi ordered the army to erect several mounds on the periphery and erect arrow towers, so that the height of the arrow towers was higher than the height of the city wall of Guangzong County.

Then the crossbowmen condescendingly shot arrows into the city walls, and the Yellow Turbans in the city could not raise their heads, and they lacked shields, and even more qualified crossbowmen, so they could only walk around with their bodies bowed all day long, and if they didn't pay attention, they would be shot into hedgehogs and die.

In the end, they actually used wooden door panels to defend the head of the city against the rain of arrows of the Han army.

But the methods of the Han army are like this, and perhaps the siege methods of this era are also like this.

At this time, there was no such variety of heavy siege weapons as later, and there was really nothing to be done about the city wall, although Lu Zhi was bent on breaking the city, he could only use up Zhang Jiao's grain and grass in this way.

Although Guo Peng also believed that Zhang Jiao did not anticipate his fiasco in advance and would not leave too much food in Guangzong, he was very dissatisfied with the fact that they could only break the city after they ran out of food.

Now the siege means are really very scarce, making people helpless in the face of the fortified city, Guo Peng knows the trebuchet, but he doesn't know why this thing is.

He knew everything about the principle of levers, but if he wanted to do it, he didn't know anything about carpentry.

The trebuchet was used in the Spring and Autumn Period and the Warring States Period, but unfortunately it was lost for a time, and then it was recorded in the history books again, that is, on the battlefield of Cao Cao and Yuan Shao during the Battle of Guandu.

How Cao Cao rebuilt the trebuchet hundreds of years later and used it on the battlefield, no one knows.

Now Guo Peng just knows this concept, just like he knows the concept of artillery, but knowing is knowing, the reality does not allow it, so there is nothing to be done.

Now I can only find a way to give full play to the siege methods and the advantages of the Han army that I can master at the moment.

So Guo Peng offered advice to Lu Zhi to fight the tunnel war.

Dig tunnels in the city where the enemy cannot see, dig all the way to the bottom of the walls, and then use wooden stakes to hold the walls against them so that the walls do not fall at that time.

Instead, when the excavation reached a certain depth and width, all the wooden stakes were burned in one go, so that the unsupported walls would collapse directly, and the soldiers from outside the city would be able to rush into the city and attack.

This method is secretive, the possibility of loss is small, but the disadvantages are also great, and the main tool for restraining this method is the listening urn that appeared in the Warring States period.

When Yuan Shao attacked Yijing, which Gongsun Chan had built with all his might, he used this method to destroy the Yijing City Wall, which Gongsun Chan regarded as impregnable, which directly contributed to the defeat of Gongsun Chan.

During the Battle of Guandu, Yuan Shao's old tricks were repeated and used to deal with Cao Cao.

As a result, Cao Cao had already prepared, and learned of Yuan Shao's attempt with the listening urn, so he led the Guandu water to the tunnel mouth and poured it in, so the engineering troops that made great contributions to Yuan Shao were wiped out by Cao Cao's regiment.

The fact that the same approach to different enemies yields different results is enough to prove that any stratagem makes sense, just by looking at the person against whom it is being dealt with.

A battlefield veteran like Cao Cao would naturally guard against Yuan Shao's use of such a method.

It is estimated that Yuan Shao himself likes to brag, and the relationship between Yuan Shao and Cao Cao was not bad at that time, maybe Yuan Shao bragged to Cao Cao about his military exploits, but Cao Cao remembered it in his heart and yin Yuan Shao.

Zhang Jiao does not have sufficient battlefield experience, and in the face of a battlefield veteran like Lu Zhi, the prototype is revealed as soon as he fights, which shows that this person is not a general at all.

Maybe there is no time to accumulate experience and no time to grow, so it may be okay to use this method to deal with Zhang Jiao.

For Lu Zhi, such a method must be tried, otherwise it will only be suppressed by a rain of arrows, and the Spirit Emperor will probably keep urging, right?

Lu Zhi also didn't want to gamble his fate on the amount of grain stored in Zhang Jiao, which was completely out of his control, so he also actively sought other plans, and tunnel warfare was one of the plans.

In order to cooperate with the tunnel warfare, the siege battle during the day did not stop at all, and the Han army kept beating drums and shouting and shooting, which brought great psychological deterrence to the Yellow Turban Army in the city and also suppressed their attention.

During this period, the Yellow Turban Army in the city finally moved, and they opened the city gate and went out of the city to counterattack, destroying the mounds and arrow towers of the Han army.

Lu Zhi was prepared and immediately sent troops to fight with him, Guo Peng once again led the Changshui cavalry to the battlefield, and repelled the Yellow Turban Army three times in a row out of the city to fight back, killing more than 1,000 Yellow Turban Army.

After successive military exploits, Lu Zhi increased the number of Guo Peng's troops, and asked Guo Peng to lead 500 cavalry, 1,500 foot soldiers, and crossbowmen on more than a dozen arrow towers to attack the south gate of Guangzong County, so that Guo Peng undertook the main task of attacking a city gate.

After Guo Peng received the order, he carefully responded to the counterattack of the Yellow Turban Army, and there was always someone around him with a shield to protect him.

Whenever the Yellow Turban Army planned to counterattack, Guo Peng rarely went into battle in person, but sent Xiahou Yuan and Xiahou Yuan to lead the troops to fight back, commanding in the rear, while taking care of the excavation of the tunnel.

Since the excavation of the tunnel, the Yellow Turban Army seems to have no signs of destruction, and the target of the attack out of the city is the mound and arrow tower, not the tunnel, which makes Guo Peng feel a little relieved.

If the Yellow Turbans could not have discovered that the Han army was digging tunnels, Zhang Jiao would have been defeated within a month, unless Zhang Jiao could perform a miracle.

Zhang Jiao is not a handsome talent in the end, and he has not created miracles.

He didn't find out that the Han army was digging tunnels to destroy Guangzong County, and was fighting a defensive counterattack war wholeheartedly, and wanted to fight with the Han army, and felt that the Han army couldn't fight him, but the result was a pity, the Han army could fight him.

On June 27, the Chengnan tunnel supervised by Guo Peng was the first to be completed.

On June 28, Lu Zhi ordered the wooden stakes to be set on fire, and with the expected sound, the walls of the county town of Guangzong, which were not tall and strong, collapsed.

"Killing the enemy and making meritorious contributions is today! Ladies and gentlemen! Kill!!! ”

Guo Peng took the lead, did not ride a horse, and the soldiers around him did not ride a horse, all on foot, armed with infantry weapons, and rushed to the collapse of the city wall with Guo Peng.

The Yellow Turban Army resisted desperately, the Han Army desperately assaulted, and the two sides launched an extremely tragic and undisciplined white-knuckle battle.

Guo Peng took the lead, the first to lead the army to rush to the city wall, the first to open the passage and rush into the city wall, killing the blocking troops of the Yellow Turban Army, and opening the passage for the follow-up main forces.

Lu Zhi's overseer army was behind, and with a wave of his sword, the drums of war suddenly and rapidly beaten, and the Han army launched a general attack.

Guo Peng led the 2,000 soldiers under his command to assault all the way forward, rushing forward like crazy, and no one in front of him could resist their charge.

Some of the Yellow Turban Army ran away frantically, and some also frantically stepped forward to fight against the Han army, but whether it was weaponry or combat skills, the Han army was better.

In addition, Lu Zhi promised a rich reward, so instead the officers rushed to the front, and the soldiers followed.

Everyone wants to get this hard-won wealth with red eyes, and their hearts are full of wealth, and they don't care about their own lives at all.

Guo Peng would not have been like this, but when he encountered this kind of thing, in such an environment, he was more fierce than other officers, rushed faster, and was even more desperate.

Wield the knife to slash the enemy, slash until his ring head knife breaks, and snatch the ring head knife in the hand of the Yellow Turban sergeant on the opposite side and turn it into his own weapon and then slash.

The soldiers protected Guo Peng and marched with him, and the corpses killed accumulated into mountains and rivers of blood, and everyone was as if they had been washed in blood, and they were angry.

People can really die for the sake of wealth.

A large number of Han troops poured into the city of Guangzong, and the city of Guangzong was in chaos, in addition to the Yellow Turban Army with weapons, you can also see women, children, old and young, all of whom are the families of the Yellow Turban Army.

The Han soldiers did not have any mercy on him, and they slashed and slashed, and the entire Guangzong City was full of ghosts crying and wolf howls.
