Cao Xiu did not lie. It is true that there will be reinforcements in a few days, but how many reinforcements can be there is a problem. Yanzhou is Cao Cao's foundation. In order to prevent Yuan Shao from crossing the Yellow River to directly attack Xuchang, it is impossible to mobilize many of Yanzhou's troops. Cao Xiu

Reinforcements from Sishui Pass and Luoyang were recruited.

He saw clearly that once Tongguan was lost, the remaining Bishui Pass and Luoyang could not be defended at all. It was better to concentrate all the troops on Tongguan. Even if they could not defend it, they could delay Liu Bei for a while and buy time for Cao Cao.

.The combined reinforcements from Sishui Pass and Luoyang are only a drop in the bucket even if they are sent in full force.

"Commander Xun, I'm afraid I really won't be able to last much longer!" Cao Xiu murmured in his heart. At this time, the only hope Cao Xiu had in his heart was the letter sent to Xuchang.

The next day, at the foot of Tongguan City.

Liu Bei led his army to line up under Tongguan. He looked at the dozens of behemoths in Yuan Shu's army not far away, and was amazed in his heart. Dozens of catapults were arranged neatly in a row, which looked very spectacular.

"With such a heavy weapon, Tongguan can be dropped with just a few clicks." Liu Bei sighed.

Yuan Shu looked approvingly at the catapult built overnight and shouted in a low voice: "Let it go!"

The soldiers who had been prepared quickly began to take action, but within a moment, countless boulders roared towards the Tongguan City Wall.

"Lie down!" Looking at the countless behemoths in the sky, Cao Xiu's eyes were filled with fear and he shouted in a loud voice.

This is not the first time that catapults have appeared on the battlefield. The princes of the world have been prepared for this for a long time and have figured out how to defend against this thing. Cao Cao relied on the power of catapults when he captured Tongguan, but he did not expect that now

Things are changing. Also in Tongguan, the person being attacked was himself.

When Cao Jun's soldiers heard this, they scattered in all directions, found the corners of the city wall, and fell down one after another.

"Boom! Boom!"

Countless boulders hit the city wall, but more boulders failed. Even if Cao Cao's soldiers dodged under Cao Xiu's command, they did not suffer much loss. Except for a few who were really unlucky and were directly hit, the rest

The soldiers were almost unscathed, and even those hit by flying gravel were only minor injuries.

Yuan Shu was not surprised when he saw this, and continued to order his soldiers to throw boulders, especially targeting the towers and gates of Tongguan.

Countless boulders flew up and headed towards Tongguan. Yuan Shu's soldiers took turns to bombard them until the boulders prepared were thrown away. Less than half an hour had passed. However, the city walls and gates of Tongguan seemed to be completely empty.

Despite the changes, it is still standing, with only some damage and collapse on the city walls.

"The danger of Tongguan is indeed worthy of its reputation!" Yuan Shu praised.

"Bang the drum, attack!" Fazheng shouted.

The rapid beating of drums sounded, and Huang Zhong and Pan Feng led the army to rush towards Tongguan. Liu Beijun had already launched a charge at the moment when the stone throwing was over. Both sides, one on the left and the other on the right, rushed straight to Tongguan, crazy.

The siege began again.

This battle lasted from morning to evening without stopping at all. Under the fierce fighting between the three parties, the entire city wall of Tongguan was almost completely covered with blood. Yuan and Liu each left more than 2,000 corpses and took away more than 4,000 Cao troops.

After the defenders retreated, at night, Yuan Jun once again launched a sneak attack, which kept the defenders at Tongguan awake at night.

In the early morning of the third day, it was another brand new day. In addition to Cao Xiu, who had always been standing ready and had never left, there was a high-spirited counselor on the city wall of Tongguan, Chen Deng.

As soon as he received the letter from Cao Xiu, Xun Yu guessed Liu Bei's plan and immediately asked Chen Deng, the most proficient in military strategy and tactics among Cao's troops except Xi Zhicai who accompanied Cao Cao on the expedition, to rush to Tongguan with 5,000 reinforcements.

Come.

Chen Deng also knew that the matter was urgent, so he rushed to Tongguan last night without even stopping.

"Commander Chen, you see, Yuan Shu and Liu Bei are attacking almost day and night. If this continues, Tongguan may not be able to be defended in a few days." With a backbone to rely on, Cao Xiu finally breathed a sigh of relief and put it away.

He pretended to be calm and anxious on the surface.

Chen Deng looked at the separate camps set up by the Yuan and Liu armies in the distance, and raised his lips slightly: "It doesn't matter, I have my own plan. Although the Yuan and Liu armies are powerful, they are just an alliance after all. What's more, Liu Bei and Yuan Shu were old enemies.

The gap between them is hard to sell. Yuan is strong and Liu is weak. As long as I use some tricks, the other party will definitely be defeated."

Cao Xiu's expression changed slightly and he said, "Is the military advisor planning to use a stratagem to alienate you?"

Chen Deng shook his head gently: "Both Yuan Shu and Liu Bei are not mediocre masters. It is completely ridiculous to use estrangement tactics at this time. They will never believe it. They don't trust each other at all. The alliance is just forced by the situation, and

How can there be any estrangement?"

"Then what strategy does the military advisor plan to use?"

Chen Deng shook his head gently: "A certain person has just arrived recently. The other party will definitely strengthen their defenses. It is better to defend the city wall first and talk about it in a few days. By the way, have you finished the catapult I asked you to dismantle?"

Cao Xiu cupped his fists and said, "According to the military advisor's instructions, I have asked the soldiers to disassemble all the catapults and reassemble them into trebuchets, which will be installed on the city wall later."

"Yes." Chen Deng nodded and turned to look at the inner wall behind him that he ordered his soldiers to build overnight: "Let me see what other clever tricks Yuan Jiujiu and Liu Xuande have."

Soon, Yuan Shu and Liu Bei once again organized their troops and arrived at Tongguan. Yuan Shu placed the catapult at the front of the army as usual, preparing to throw several waves of stones to damage the morale of the Tongguan defenders.

However, Yuan Shujun's catapult had just been pushed up and set up. Before Yuan Shu could give the order, he heard a familiar and terrifying roar in the air.

"Boom! Boom!"

Countless boulders fell from the sky, covering the vicinity of the catapults.

"What's going on?" Yuan Shu asked with dull eyes.

Before Yuan Shu could react, numerous boulders had already fallen, not only destroying three or four catapults, but two boulders directly smashed into the unsuspecting army, causing numerous casualties.

"Disperse! Retreat!" Yuan Shu and Fazheng shouted quickly. The sudden blow made them a little panicked, and they retired one after another before talking.

After Yuan Shu suffered dozens of soldiers and three trebuchets damage, he withdrew from the range of the trebuchets above Tongguan.

"Xiaozhi, what should we do now?" Yuan Shu asked.

Fazheng looked at Tongguan from a distance and saw Chen Deng who had stood up on the city wall at some point. Looking at the confident eyes and faint smile on the corner of his mouth, Fazheng sighed softly: "My lord, the morale of the army is now high."

Feeling down, we’d better retreat to the camp for the time being and reorganize it first.”

The appearance of Chen Deng directly made the already one-sided situation become confusing again.
