At noon on the third day of the Battle of Tongguan, because of the trebuchet placed by Liu Ye on the city wall in the morning, Yuan Shujun's defenseless losses were not small and their morale was greatly reduced, so they chose to withdraw temporarily. At noon, he regrouped, reorganized the army, and fought with Liu Beijun to Tongguan. This time, Yuan Shu directly gave up carrying the catapult and led the army to rush up against the endless flying stones above Tongguan.

After half a day of fierce fighting, Yuan and Liu left about 5,000 soldiers and soldiers in exchange for more than 3,000 Cao army casualties and retreated.

On the fourth day, the battle situation was even more tragic, and Liu Bei was also ruthless, and directly sent all the soldiers around him, leaving a thousand elite soldiers to guard him. Because of the four days of fierce siege of the city, the army under his command suffered too heavy damage. Liu Bei worked so hard, Yuan Shu naturally couldn't paddle, although he didn't go out openly, but it was also a full 50,000 army to overwhelm the realm.

Under the absolute suppression of troops, Chen Deng is also a clever woman who has no rice, he can plot to suppress Yuan Shu's two major advantages, but it is impossible to scatter beans into soldiers, Tongguan is still facing a very dangerous situation. Even with the addition of more than 5,000 new reinforcements, the current Tongguan soldiers are still about to drop to 20,000, and Yuan Shu's harassment overnight has also exhausted the soldiers defending the city.

That night, after repelling the harassment of Yuan Shujun again, the gate of Tongguan was quietly opened, and a large army slowly emerged, numbering nearly 10,000, all dressed in Yuan Shujun's armor and clothing, heading towards Liu Beijun's camp.

"Strategist, whether Tongguan can be defended or not, I'm afraid it depends on tonight." Cao Xiu stood on the city wall and said to Chen Deng.

"The army is ready, if Liu Bei's army bombs the camp, we will immediately lead the army to attack it." Chen Deng said.

"But what if the other party doesn't get the plan, but will plan it?" Cao Xiu said cautiously.

Chen Deng glanced at him lightly: "Do you think that if we don't take advantage of this opportunity, we will still be able to repel the Yuan-Liu coalition army?" Or do you think we have a better chance after tonight? ”

Cao Xiu's heart was also pang when he heard this. Indeed, they have no choice, fight to the death, win if they succeed, and defeat if they don't, it's better than waiting for death. According to the siege intensity of Yuan Shu and Liu Beijun, they just stubbornly held on, and it is estimated that they will not be able to hold it for even five days.

Soon, in the watchful expectation of Cao Xiu and Chen Deng, there was really a fire in Liu Beijun's camp in the distance, and the killing sound lasted for a long time.

"Troops!" Chen Deng relied on his extraordinary five senses, and saw the situation in Liu Beijun's army for the first time, and said directly.

Cao Xiu did not hesitate at all after hearing this, and directly jumped off the city wall eagerly, leading the army that had been prepared to go out of the city in two ways, and galloped towards the camps of Yuan Shujun and Liu Beijun respectively. And what is amazing is that the number of the two armies is actually more than 20,000, which looks huge.

On the city wall, countless fine droplets of sweat faintly appeared on Chen Deng's head, and his breathing was a lot shorter. His spiritual talent is bluffing, and he can disguise a small number of soldiers into a large army. The previous scene was his masterpiece, which was why he had hope for the success of the night raid. Otherwise, if he only relied on an army of more than 10,000 people, how could he cripple Liu Beijun on the basis of blocking Yuan Shu?

Chen Deng knew that he was too hasty and inappropriate to do so, but he had no choice at all. The military strength is crushed, even if he can use various means to reduce the damage of his own defenders, but the base of the force is there, even if he hits a 1-2 battle loss, what can he do? Strategically speaking, it is still a loss.

Chen Deng knew that the only opportunity he could take advantage of was the gap between Yuan Shu and Liu Bei. Therefore, in his planning, tonight's small force raid, if it fails, he will throw the pot on Yuan Shu, not asking Liu Bei and others to believe, as long as he can confuse Liu Bei's soldiers, and then he will spread rumors among Liu Bei's army, and there is a great chance to directly provoke the hatred between Liu Bei and Yuan Shu's soldiers.

And if it succeeds, as he sees, he will send two armies to attack the two camps. Among them, the army that attacked Yuan Shu's military camp seemed to be more than 20,000, but in fact it was only more than 1,000 people. It seems that the momentum is huge, but it will be crushed with one blow, Chen Deng is betting on Yuan Shujun's attitude towards Liu Bei, the 20,000 army is placed outside the Yuan Shujun camp, it depends on whether Yuan Shu will directly choose to rescue Liu Beijun immediately.

On the other side, the more than 20,000 troops attacking Liu Bei's army were actually more than 10,000 troops, which was already all the remaining troops of Chen Deng except for the 3,000 soldiers guarding the pass. If this night attack could not directly beat Liu Beijun from the bombing camp to cripple, his night attack would have failed.

At this time, looking at the two camps in the distance, Chen Deng, who was worried in his heart, did not know that in the Yuan army camp, Yuan Shu, who had rarely stayed up late, did not rest at all at this time, and stood on the lookout platform of the Yuan army camp with Fa Zheng, also looking at the direction of Tongguan and Liu Bei's army camp from a distance, with a slightly happy face.

"Here we go!" Yuan Shu said with a smile.

"Although Chen Deng is full of scheming, it is far easier to deal with this kind of arrogant smart person than to deal with a stupid person like Cao Xiu. In the unfavorable situation, the stupid person will insist on sticking to the death, while the smart person will fight to the death with the sword. Fa Zheng said lightly.

"It seems that after tonight, this Tongguan will be ours." Yuan Shu looked satisfied. Originally, he planned to directly attack and take Tongguan, although the time was about the same, but the loss of troops really made him feel distressed. In the four days of siege alone, he lost more than 5,000 soldiers, and if it weren't for the proper treatment of the medical soldiers under his command, this number would have doubled.

The battle damage in the siege was really terrifying, and most of the soldiers died directly and were not injured, or they were slightly injured, and they had to fall directly to their deaths if they were driven down the ladder. Therefore, the medical and nursing soldiers, who were originally able to reduce the loss of nearly eighty percent of the troops, only reduced by more than fifty percent in the siege battle, and their role was greatly reduced.

"But then again, your spiritual talent is really suitable for fighting with the army, if the other party doesn't have an understanding of your ability, it is estimated that you will have to be hit." Yuan Shu sighed lightly.

Although Chen Deng is a little arrogant, he is also a first-class top strategist. In history, he sat in Xuzhou, which made Sun Ce and Sun Ce's army sink into the sand several times, although he is not obvious, but he is definitely a person with far-reaching wisdom. Fa Zheng was able to easily calculate with him this time, purely because he had a heart and no intention.

After all, Chen Deng's character, as well as the other party's style of acting and spiritual talent, were clearly understood by Yuan Jun in the battle of the family's attack on Yangzhou as early as the original period when the princes were fighting for Dong. However, Fa Zheng has not been famous because he is still young, and his spiritual talent is not an exposed talent like Chen Deng, even if he uses it, the other party can't see it, unless the same top strategist calculates a few times, it is estimated that he can guess it.

Fa Zheng's spiritual talent was not so incomprehensible, and with such a distance, Fa Zheng couldn't detect Chen Deng's mood swings at all. Because both sides are top strategists, Chen Deng's spiritual talent is not inferior to Fa Zheng, that is, he is facing him face to face, if the other party is on guard, Fa Zheng will not be able to detect a thing or two. When Yuan and Liu were negotiating, Liu Ye was also defenseless, so he was recruited. However, after that, Liu Ye vaguely guessed something, after all, the changes before and after the negotiation of the law were completely like two people, and it would be strange if there was nothing greasy among them.

Fa Zheng knew the scope of his ability, so he was not aiming at Chen Deng at all, but Cao Xiu. Although Chen Deng actually commanded Cao Xiu, Cao Xiu was the nominal supreme general of Tongguan after all, and the defenders of Tongguan were under his control, and Chen Deng only existed as his military advisor. Therefore, if Chen Deng wants to send troops to attack at night, he must discuss with Cao Xiu in advance, and even let Cao Xiu lead the troops.

Chen Deng's spiritual power is strong, and the Fazheng is difficult to find. But Cao Xiu, a military general, doesn't have such a strong spiritual power, although the internal qi can also block the spiritual talent of Fazheng, but he is not involved in the battlefield, who has nothing to do and waste his internal strength to protect himself? Cao Xiu's martial arts are not outstanding, and he has been hiding in the rear, and Fa Zheng is simply a catch.

Having guessed in advance that Chen Deng was likely to take the initiative, Fa Zheng had been paying close attention to Cao Xiu's mood swings, constantly speculating about the time when Chen Deng might act.
