According to the current progress, it will be dug in three days. Xu Yu said.

Progress has always been under control.

It's a little slower these days, otherwise you can dig through it now.

But if the speed is fast, the movement will be big, and it may have been discovered by Cao Cao.

"Cao Cao is only suspicious now, he shouldn't know that we are digging tunnels yet." Guo Jiadao.

Xu Yu said: "If Cao Apu knew that it was an authentic tunnel, he would not have sent a dozen spies to send him to death." ”

Both of them believe that this tunnel will continue to be dug, and it will only be cleared, and they cannot give up at this time.

Zhao Hui said: "But Cao Cao now suspects that the spies from last night did not go back, and he will definitely send more people out today." ”

If you continue to dig, there is a high probability that Cao Cao will discover the tunnel.

Then all the work done is lost.

But at this time, it is impossible for them to give up, it only takes three days to become.

Guo Jia said: "Cao Cao didn't see these spies go back today, and he will definitely send more spies in the evening, and it is very likely that Xu Chu Guan Yu will be sent." We can take the opportunity to set up an ambush so that they will not return. ”

Cao Cao has a lot of spies, even if he kills a dozen a day, for Cao Cao, it is not a problem.

But if you can kill several of Cao Cao's generals, the blow to Cao Cao will be even greater.

"Set up an ambush in the woods tonight." Zhao Hui ordered.

Cao Cao, who was in the city, waited all night and didn't see the spies come back.

By the time dawn, Cao Cao already knew that those spies would not be able to come back.

"Ang'er should be fine."

Cao Cao sent Cao Ang to Wancheng, saying that it was impossible not to worry.

But as his son of Cao Cao, he must not be a flower.

Even if it was dangerous outside, Cao Cao still sent him there.

Cao Cao, who hadn't slept much all night, slept very deeply after dawn when he returned to his room.

Although the situation was unfavorable, although he was worried about Cao Ang, when it was time to sleep, Cao Cao fell asleep quickly.

Instead of worrying about being uneasy, he should keep his spirits up.

After sleeping until late in the afternoon, Cao Cao got up and washed his face, ate two more flatbreads, and then sat down at the head of the city.

His eyes kept looking at the camp of the Zhao army outside the city, as well as the terrain outside the city.

Everything outside the city, Cao Cao didn't know how many times he had watched it, and these pictures had already been deeply engraved in his mind.

He could even close his eyes and draw the terrain outside the city, as well as the camp of the Zhao army, and the patrol that the Zhao army appeared.

Sitting at the head of the city every day, in addition to stabilizing the army's heart, Cao Cao is also looking for a breakthrough for the Zhao army.

If he could, Cao Cao didn't want to fight a protracted war.

Too much food and grass is consumed, and the longer it drags on, the lower the morale on his side will be.

Even if he and Liu Xie are in Guandu, their status is not endlessly motivating morale.

When they are no longer mysterious and noble, their status in the hearts of the soldiers will naturally decline.

When Cao Cao appeared on the city wall, Zhao Hui was in the camp, holding a clairvoyant in his hand, looking at Cao Cao on the city wall.

There are more than five miles apart, but under the clairvoyance, the beard on Cao Cao's face can be seen clearly.

Cao Cao on the city wall, his every move was under the observation of Zhao Hui, as well as Guo Jia, Xu Shu and others.

It's just that Cao Cao's expression is very indifferent, he hides it very well, just looking at Cao Cao's expression, even Guo Jia, he can't see anything.

Cao Cao sat on the city wall until dusk, during which Xun You, Zhong Xuan, Xu Chu and others all appeared beside Cao Cao.

Under the observation of clairvoyance, it can be seen that Cao Cao said something to them, but he can't know what Cao Cao said.

"It's dusk."

Seeing Cao Cao disappear from the city, Zhao Hui also put away his clairvoyance.

"Zilong, evil is coming, you go to rest first, it is estimated that there will be another fierce battle tonight." Zhao Hui said.

He himself is also going to sleep for a while to recuperate.

The last time Yanjin pursued Cao Jun, Zhao Hui went in person.

Tonight's forest, Zhao Hui still has to guard it personally.

He wanted to meet the generals under Cao Cao again.

The last time Yanjin pursued, Xu Chu Guan Yu and Zhang Fei escaped, and tonight he wanted to see who else Cao Cao would send.

In the evening, Zhao Hui and Dian Wei went to the forest to the north.

Zhao Yun and Xu Huang went to the forest in the south.

Hide near the entrance to the tunnel.

In the city, Cao Cao also sent a new exploration horse.

Yesterday he sent out a total of thirty spies, eighteen of whom were to investigate the forests on the north and south sides, but none of them returned.

In addition, there were twelve spies, mainly to investigate Zhao Hui's camp and other surrounding areas, and eight of them returned.

This made Cao Cao even more determined, and the forests on the north and south sides have now become Zhao Hui's military powerhouse.

He had to figure out what was in the woods.

If he can't figure it out, Cao Cao will have trouble sleeping.

Knowing oneself and knowing one's opponent is Cao Cao's first creed when he was fighting.

According to Zhao Hui's current army outside the city, Cao Cao can still block it, so he can sit at the head of the city and watch the scenery every day.

But if Zhao Hui didn't attack, but had other actions, Cao Cao would have no bottom in his heart.

"Xu Chu, Guan Yu listens to the order."

"The last general!"

"Tonight, the two of you follow the spies out of the city and go to the forest in the north to check the arrangement of Zhao Jun in the forest."

"The last general commands!"

"Cao Ren and Cao Xiu listen to the order, and the two of you go to the forest in the south."

"The last general commands."

"Xuande, I still need your help tonight." Cao Cao said to Liu Bei.

"Prime Minister don't worry, I will let Chen Zhi follow General Cao Ren to the south of the forest together."

"Big brother, I'll go too."

Zhang Fei, who was following Liu Bei, said.

"But your arm injury isn't healed yet." Liu Bei said.

Zhang Fei waved his left hand: "This little injury is almost healed, and it won't have an impact." ”

There is no effect at all, it is definitely fake.

But Zhang Fei really wanted to go out of the city, and he wanted to fight Zhao Hui again.

"You stay." Liu Bei did not agree.

He couldn't let Zhang Fei take risks anymore, there were only a few people in his hands, and the death of any one of them was enough for Liu Bei's heartache for a long time.

Unlike Cao Cao, even if there are many generals who have died in the hands of Zhao Jun now, but looking at the generals under Cao Cao's current command, they are still full of talents.

Zhang Fei wouldn't listen to other people's words, but Liu Bei's words were different, even if he wanted to go very much, Zhang Fei still endured it.

But after leaving, he immediately took a large jar of wine and drank it sullenly.

There was still a white cloth wrapped around his arm, even if the doctor couldn't drink alcohol, how could Zhang Fei care.

If your heart is not happy, you will drink. I didn't use a wine bowl, I just hugged the wine jar.

By the time Liu Bei came back, Zhang Fei had already been drunk and unconscious, and he was asleep holding the wine jar.
