This time, Cao Zhi had experience getting out of the tunnel, and took off his armor and wore short-striped cloth pants. He didn't match the Qinhuang Sword, but only brought the full moon scimitar as a close-fitting dagger. With such a lightweight clothing, he became much more flexible and refreshing, unlike when he took a few steps last time, he was sweating all over.

"Dong, dong" with familiar sounds, people with yellow crawled in and out.

Li Hei's achievements this day and night were amazing, and he made a great stride. Especially after Cao Zhi left, he dug a zigzag bend between the soil in the middle of the city wall.

Zhou Cang took an oil lamp and looked forward, asking in confusion: "It seems that Li Hei is not an ordinary person, why did he make the tunnel like this?"

Cao Zhi looked at the entire tunnel in a zigzag shape and crawled with his experience of watching tunnel warfare since childhood and replied: "In architecture, even if a small-scale collapse occurs, it will not cause great danger. Moreover, it is possible that Li Hei will use it to save his energy to bypass those rammed earth with foundations."

Zhou Cang said, "Oh!", then looked at Cao Zhi in front of him strangely, and muttered a few words, "Architecture, what is architecture?"

After Cao Zhi and Zhou Cang climbed through this zigzag passage, the sound of "dong, dong" became clearer.

Cao Zhi was shocked when he saw Li Hei. Li Hei should still be shirtless, but he could no longer see the difference between his skin color and his clothes color. He was gray and earthy, and he had become a real gray man.

Because of the heavy dust, the soldiers under the tunnel now covered the cloth at the mouth of their noses, which played the role of a modern mask. Cao Zhi and Zhou Cang were also sent a piece of such a white cloth before going to the tunnel. Cao Zhi didn't know if the cloth was still white, but there was no trace of white in front of Li Hei in front of him.

"Master!"

When Li Hei saw Cao Zhi come to care about him again, he was very excited. He rubbed the towel below and exposed two faces of different colors. He said with a foolish smile.

"Thank you for your hard work, how are you doing?"

"It has been opened. After passing this wall, it should be in Shouchun City. According to the map of Deng Juncheng, after passing the Shouchun City Wall, you will not be able to dig it for a long time to get close to the back garden of the county government. We just need to find a hidden place to shoot it out."

"Okay, it's great, we can't stay here for too long. Yanzhou's military situation is urgent. We want to withdraw troops to Yanzhou Pingshou. You can dig it up earlier. Zhou Cang goes in and walks, and you will retreat to Hefei with you. Let this place be fought for Chen Yu and Yuanzhang! quot;

"Okay, I'll work harder here and ensure that I can go to the designated location tomorrow."

As he spoke, Li Hei had to turn back and continue working.

Cao Zhi pulled him and said, "Don't be anxious, don't be anxious, you have to take a breath even if you hang yourself. You and your brothers have a rest. I see that you have never been out of the authenticity since last night. Come and eat something and drink water."

After Cao Zhi said that, he turned his head and half turned around to greet Zhou Cang behind him, and handed them over the food they had dragged in.

However, since the tunnel is now in a zigzag shape, it is extremely inconvenient to deliver things. In the end, the soldiers who were in this section of construction had to retreat a little and concentrate on the first city base to eat and snacks. Li Hei, Cao Zhi and Zhou Cang were left at the base of the city wall.

After the three of them sat cross-legged, Cao Zhi handed over a steamed bun made of white flour. Li Hei was the kind of person who could eat something and sleep with him. Only those who didn't have too many thoughts could stay in this underground work that could not see the sun and the moon for a long time, and stay for a long time.

Li Hei smiled silly, stretched out his black and covered in mud and took the white steamed bun, "Awu" and took a big bite and chewed it sweetly.

Influenced by modern hygiene habits, Cao Zhi was stunned at first. Then he smiled softly and said to himself: "This is the man in war!"

Then he turned around and took a bowl of water handed over by Zhou Cang and said, "Eat slowly, it's not time to do this, drink a sip of water, don't swallow it."

Li Hei continued to smile, and the muscles in the corners of his eyes squeezed and two pieces of ashes fell. He was still no longer able to breathe. He took the water and drank the water in the bowl in one gulp, and then put the bowl on the ground full of ashes and soil, and continued to eat the steamed buns in his hands.

Cao Zhi smiled and picked up the empty bowl on the ground, turned around to help Li Hei add water to Li Hei. Zhou Cang also smiled and snatched the water bowl from Cao Zhi, half-squatted behind him and took a bag and a jar of water. He helped Li Hei pour the bowl of water again, pulled two steamed buns from the bag, and handed them to Li Hei.

The steamed bun in Li Hei's hand was almost gone in his mouth in two. Zhou Cang handed it over with more amounts, but he just laughed a little embarrassedly and accepted it all.

It is rich to be able to eat. Most of the generals around Cao Zhi have a lot of appetite. But in the past, Xu Chu was the best to eat, but today's record seems to be broken by Li Hei.

Zhou Cang picked up a pack of steamed buns and a jar of water from the food he brought into the tunnel to the end of the tunnel. He thought that most of the workers were given to Li Hei, and he and Cao Zhi could accompany him to eat one or two. But now it seems that there is no hope. There are at least a dozen buns of steamed buns, and now they are almost finished by Li Hei one after another, and there is no sign of this black guy being full.

Zhou Cang had handed over two white flour buns that were five or six times on the side, and from the beginning, he shook his head and sneered into a expressionless cursing lips. Just as Zhou Cang was worried that he would take less food, he suddenly heard a muffled sound.

The three people in the tunnel all had a meal, and I don’t know what the sound was. Cao Zhi and Zhou Cang’s first reaction was that the tunnel had collapsed, and they were looking around. Li Hei was still experienced underground. He stopped eating half of the steamed buns, half-squatted and stood up, stuffed the steamed buns into the clothes on his waist, grabbed the hammer buried in the soil beside him, and said to Cao Zhi who was looking around, Zhou Cang said: "Lord, don’t look at it, it’s because it’s thunder outside, and it will sound like that when it reaches the ground. It seems that it will rain, and I have to dig it quickly. After the rain has been raining for a long time, it will easily penetrate the tunnel. Zhou Duwei, please come and greet my subordinates in front and tell them not to eat, come and dig quickly."

"Ah!" Zhou Cang responded quickly, turned around and went around the zigzag bend to call the soldiers resting on the other end.

Li Hei stopped calling Cao Zhi. He copied the hammer in his hand and turned around and smashed it on the foundation of the city wall.

Cao Zhi saw that he didn't bother others to work, so he should leave quickly! Just as Cao Zhi turned around and was about to climb the zigzag curve, with Li Hei's fierce attack behind him, a large piece of gravel and sand fell down.

Cao Zhi turned his head when he heard the sound. He saw that he was behind him. What a big city base this time he dropped, about one square.
