Qian Xiaoxing nodded and replied, "There is a solution, but it's a bit risky. But the old saying goes, "If you don't enter the tiger's den, you can't get a tiger's son. This time we have to go deep into the tiger's den..."

"What the hell do?" Lu Shengzhong asked excitedly.

Qian Xiaoxing kept a secret and said, "Hehe! I'll know then. By the way, Brother Qi has recently blocked Panlong Pass and cannot let anyone go. If the news leaks and Hu Jun is alert, it will not be possible."

"Well, I've long thought of this. Panlong Pass has been closed and no one can go out." Lu Shengzhong replied.

After hearing this, Qian Xiaoxing smashed his hand with his fist and said, "Okay, when the materials for building the Sky Pass are ready, it will be the time to break the Dragon Chat City!"

In the following days, the National People's Congress mobilized the people of the State of Si, and many people came to do voluntary labor spontaneously. The quarry and wood mining farm were crowded and busy. Because the business road was blocked and the goods were hoarded, Qian Xiaoxing ordered Uncle Xu to temporarily suspend production of the Qian Group factory, and all employees gathered here to provide support.

On the busy construction site, people came and went. Qian Xiaoxing was constantly directing the workers to work, and his voice was hoarse. Si Yingying personally brought a bowl of water to Qian Xiaoxing and said, "Brother Xing, you drink water."

Qian Xiaoxing took the water and suddenly remembered the scene when Lan Xiaocui gave her mung bean soup to drink when she was working. She couldn't help but miss her. How good is that cute Xiaocui now? She is so busy that she has not even had time to miss her. It's really not worth thinking about it.

Seeing Qian Xiaoxing stunned, Si Yingying asked, "Brother Xing, what are you thinking?"

Qian Xiaoxing came back to his senses, thinking about Lan Xiaocui's virtuousness, and sighed: "The happiness of a woman is to marry a man and serve him for the rest of his life."

When Si Yingying heard this, she cursed: "Why didn't he serve me all his life?"

Qian Xiaoxing shook his head and said, "I know why you can't get married yet."

Si Yingying angrily let out a "slap" and turned around and left angrily. Xiong Yitan and Hu Suoyuan who were helping in front came over and sat down next to Qian Xiaoxing to rest. Hu Suoyuan asked lustfully: "Chief of Staff, such a beautiful girl, when do you want to do something with her?"

"I'm still training, I'll do it when I'm obedient." Qian Xiaoxing also found a big stone to sit down after he said that.

Hu Suoyuan retorted: "Chief of Staff, you are inexperienced. Women, you will be obedient only after you have to do it."

"Oh?" Qian Xiaoxing did think for a while after hearing this, and said, "Well, if you have the chance, you will push it down. But Hu Suoyuan, you won't think of her too, I warn you that if you touch Yingying's mind, you will regret it for the rest of your life."

Hu Suoyuan waved his hand and replied hurriedly: "Chief of Staff, you are too bold to see me. Don't say that she is the Princess of the State of Si. Even if she is the Chief of Staff, you will not dare to think about it at all."

Qian Xiaoxing nodded with satisfaction and asked caringly: "Is there any relatives at home when I return to Si State this time?"

Hu Suoyuan nodded and replied, "There is another father-in-law. When he comes back this time, he has several more mother-in-laws."

Qian Xiaoxing shook his head helplessly and said, "Hu Suoyuan, you are so lustful. You found several women as your wives in one go."

"No, Chief of Staff, you misunderstood me. It's because my father-in-law is so powerful. I have found several wives. Isn't there a few more mother-in-law?" Hu Suoyuan defended.

Qian Xiaoxing laughed secretly when he heard this: "So that's it, then don't you want to look for it?"

"This, actually, when I was a bandit, I did not restrain Hu Tian and Emperor Hu. Now I am the chief of staff's guard. So I can do such a thing again. If my wife says I will find him when he is restored, I will look for him." Hu Suoyuan said with a smile.

Qian Xiaoxing then asked Xiong Yitan: "Boss Yitan, where are you?"

Xiong Yitan replied: "Chief of Staff, how can you call me the boss? Just call me a jar. I have no worries anymore. My family has been killed by Hu Jun. This time he killed 60,000 Hu Jun. The Chief of Staff is really amazing. I admire you so much."

"This is nothing, it's just a sub-scheming." Qian Xiaoxing said stinkyly.

Xiong Yitan was even more impressed when he heard this and asked, "Chief of Staff, you are knowledgeable, tell me what will happen to the world in the future."

Qian Xiaoxing said deeply: "Long-lasting, you will be divided, and long-lasting separation, you will be combined!"

Xiong Yitan immediately applauded and said, "Chief of Staff, you are so amazing. You even know my wine tastes well. You will be crazy when you drink, and you will drink every time you drink. How do you know?"

"Ah!" Qian Xiaoxing was speechless when he heard this, so he had to continue to pretend to be deep and said, "Know yourself and your enemy and win every battle, and the whole world is in my control."

"What a worship!" Xiong Yitan's eyes showed a look of admiration.

Qian Xiaoxing couldn't help laughing and hurriedly said, "Okay, go to work soon."

The materials for the construction of the pass are all in an orderly manner. The bridges Qian Xiaoxing is responsible for building have been poured and are just waiting to be hardened.

Qian Xiaoxing drew a sketch of a new pass. The city wall is about 20 meters long and is about 20 meters high. For the convenience of construction, only two layers of arrow towers were set up on the top and a city gate was set up. However, Qian Xiaoxing added something to this city gate. Five cement boards about half a meter thick were added in the middle of the door opening. After all the cement boards were put down, a cement board door more than two meters thick was formed. Judging from ancient technology, it was almost impossible to break into the door.

The reason why cement barrier doors need to be piece by piece is that if they pour together, the weight is too large. If they are put down and cannot be lifted, there will be no roads to pass. They are divided into several pieces and can be lifted one by one. There are more people.

There is a river next to the pass, which is convenient to fetch water on the spot, so Qian Xiaoxing decided to dig a moat in front of the pass to stop the Hu army from attacking the siege and rushing cars.

The bridges on the river surface have also been designed, with three piers installed, and four sections of bridge panels can be laid. Each section is five meters long, so the prefabricated cement parts can still bear the bearing capacity.

In Guandu Imperial City, the night was already dark. Qian Xiaoxing drew a three-dimensional picture and carefully calculated the amount of earth and stone to understand whether the stones currently mined were enough.

Seeing Qian Xiaoxing seriously drawing pictures there, Si Yingying gently took a blanket to give it to Qian Xiaoxing. Now Qian Xiaoxing works day and night, but she has never had the energy to do it before.

Qian Xiaoxing looked at Si Yingying gratefully and said, "Yingying, go to bed first, warm the bed and wait for me."

Si Yingying twisted Qian Xiaoxing's arm and scolded, "I want to make a bad idea for me. I want to give myself my life to you. It's too early. I saw you work hard and I wanted to praise you a few words, but now I'm not praising you."

"I really won't praise you anymore, then I think I can only show my hand." Qian Xiaoxing pointed to the drawings and said, "Yingying, look at how many stones this city wall requires, can you calculate it?"

Si Yingying took a look and saw that the cross-sectional shape of the city wall was a trapezoid. If it was a rectangle, you could try it. She shook her head helplessly.

"I don't know, today I will teach you how to calculate area and volume." After Qian Xiaoxing drew several figures such as cubes, cuboids, cylinders, etc. on the paper, he began to teach Cheese Yingying.

After Qian Xiaoxing's careful explanation, Si Yingying quickly learned it. Finally, Qian Xiaoxing drew a sphere and said, "The size of this sphere is the most difficult to forget. By the way, Yingying, do you want to know how big the two spheres on your chest are? Why don't I calculate it for you?"

Si Yingying's face turned red and she said angrily: "I've taught you well, I'll get out of tune."

"Don't you want to know? I really want to know. Why don't you measure it for me!" Qian Xiaoxing insisted.

Si Yingying immediately covered her chest with both hands and said, "Didn't you always use your hands to measure it? You don't know how much size you have. I think you want to take advantage of it and ignore you. I'll go back to bed, so you... go to bed early too."

After saying that, Si Yingying ran out. Qian Xiaoxing sighed helplessly after seeing it. It was not that he didn't want to push Si Yingying, but that Si Yingying really refused to push it. If he got angry and used a series of slaughterless feet, he would lose his luck for the rest of his life.
