The two returned to Guandu for dinner. Qian Xiaoxing was arranged to rest in the imperial city, and his bedroom was next to Si Yingying. Today, Qian Xiaoxing was so busy that he wanted to have a good rest as soon as he closed his eyes, but he couldn't sleep because he was thinking too much in his heart.

The first thing is the most important thing. Although there is still one month left to deal with the Hu army, we must prepare for the future.

The second thing is Si Yingying's marriage. The agreed time with Lin Guo is coming soon. If Lin Guo doesn't see Si Yingying getting married and get angry and gets attacked by tens of thousands of troops, it will be a big trouble, and this matter needs to be properly handled.

The third thing is the matter of the Qian Group. To raise more soldiers, we must expand the scale of the group and create more wealth. Although there are only 4,000 soldiers at present, they must grow stronger and stronger in the future, and the expenses will be greater.

Thinking of this, Qian Xiaoxing tossed and turned, but couldn't figure it out and couldn't fall asleep for a long time. When he was turning over, he heard a knock on the door and asked, "Brother Xing, are you asleep?"

Qian Xiaoxing heard Si Yingying's voice and replied, "I can't fall asleep if I miss you, come in."

Si Yingying lifted the light and pushed the door open, came to Qian Xiaoxing's bed and sat down, and said, "Do you really miss me?"

Qian Xiaoxing grabbed Si Yingying's hand, looked at Si Yingying's eyes with affection, shining brightly under the fire, and asked back, "You don't sleep so late, do you miss me?"

"Yes, I think you must be trying to solve the current crisis of State Si. When you see that the light is still on, come and take a look. Brother Xing, don't be too busy, take a break early, and think about it tomorrow." Si Yingying said with concern.

After hearing this, Qian Xiaoxing felt warm in his heart and replied: "Yingying, thank you, but I can't sleep."

Si Yingying dragged off her shoes, climbed onto the bed and said, "You can sleep on my thighs. Isn't it easy to fall asleep?"

"I thought you went to bed to sleep with me. I was so scared that I jumped up all the time, but I warned you that I won't give you my body." Qian Xiaoxing turned around with a smile and laid on Si Yingying's thigh.

"Isn't you really not giving it to me? Then I'm so sorry." Si Yingying also smiled.

"If you don't give it, you have to know that I am a very conservative man. Don't want my body unless it's a wedding night." Qian Xiaoxing said with a smile.

"Don't mock me, why am I so conservative? Okay, close your eyes and go to bed." Si Yingying urged softly.

Qian Xiaoxing obediently closed his eyes, his mind was really clear, and he fell asleep immediately.

When he woke up the next day, Qian Xiaoxing couldn't see Si Yingying. If he had regretted the good opportunity before, he would not have pressed Si Yingying. However, at the moment of the national crisis, Qian Xiaoxing had no time to deal with this romantic matter.

After washing up, Qian Xiaoxing ate the breakfast sent by Xu Lingli, and he started to wander in the garden in the palace. It is already early March, and spring is a season of vitality. All kinds of flowers and trees have begun to grow new buds, and a vibrant field indicates a new beginning.

Does Si State have a new beginning, and will still be destroyed? Qian Xiaoxing thought that Si State currently only has 4,000 soldiers. Although there is a natural danger in Panlong Pass, the gap in strength between the forces is too great. If you can't think of a powerful weapon, you will definitely not be able to resist it. Qian Xiaoxing thought of explosives, but was very upset in his heart, because Qian Xiaoxing didn't understand the formula of this explosive, and regretted why he didn't go to Google to Baidu.

Qian Xiaoxing came back around the garden, but there was no good idea. After thinking for a while, he still called Lu Shengzhong and went to Panlong Pass to take a look at the field investigation. This was the main thing.

The two rode their horses to Panlong Pass. Now Qian Xiaoxing's equestrian skills are becoming more and more skillful, and he will not make his butt hurt. When he arrived at Panlong Pass, because Panlong Pass was originally from the Si State, Lu Shengzhong was very familiar with the city defense. However, in just one day, the soldiers' defenses were arranged in an orderly manner.

When the soldiers who passed by saw Lu Shengzhong and Qian Xiaoxing carrying two bars and one star on their shoulders, they both stopped to salute. This salute method was used by Si Guo before. The palm of his right hand was placed down in front of his chest, probably in the heart, indicating that Yixin was finally at Si Guo. The two of them respected one by one, climbing up the wall of Panlong Pass against Hu Guo.

The city wall is about ten meters wide and thirty meters long. It is all made of large pieces of stone. There is a tower in the middle, with two floors of heights, and there are observation soldiers on it for twenty-four hours. A row of neat concave and convex walls reminded Qian Xiaoxing of the Great Wall. Panlong Pass was built between two mountains, so both ends of the city wall are close to the mountains on the side.

Near the archery hole, Qian Xiaoxing thought to see that the height of the city wall was about twenty meters, which was equivalent to the height of the seventh floor of the modern day. There was an open flat ground in front, and you could see it far away at a glance.

Qian Xiaoxing saw the soldiers on the middle tower looking up and said, "Brother Zhong, that telescope, send these observation soldiers first."

"Well, this telescope is such a good thing. I can see so far, I will distribute it later." Lu Shengzhong nodded in agreement.

Qian Xiaoxing looked at the towering city wall and remembered the scene of siege that he had seen on TV before. The soldiers set up long ladders to attack the city wall, but were all killed. So he asked: "Brother Zhong, if Hu comes to attack Panlong Pass, I think it is more than 20 meters high. What method will they use?"

Lu Shengzhong explained: "Generally, using a rushing car is to use a thick piece of wood to hit the city gate with four wheels. If the city gate is broken, then attack from the city gate. Of course, when using a rushing car, they will also use a siege car together. The siege car is a large ladder that can be moved from a distance. After landing on the city wall, the enemy will climb up from the ladder on the siege car to hit the soldiers on the city wall. This ladder is not easy to destroy, so it is very threatening."

"Don't you need an ordinary long ladder?" Qian Xiaoxing asked in confusion.

"Ordinary ladders are only used when the situation is urgent, such as if they are about to be attacked or time is tight, so they can only be used for barely. However, using ordinary ladders has a lot of casualties." Lu Shengzhong analyzed.

"Rocket, siege car." Qian Xiaoxing thought that there were so many ways to attack the city. If Hu was really used by the State of Hu, the 4,000 people in Siguo would be unable to resist. After thinking, he said, "Brother Zhong, I have a way to restrict siege and siege car from coming to the city to attack."

After hearing this, Lu Shengzhong's eyes lit up and he hurriedly asked, "What's the solution? Seventh brother, please tell me."

"This rushing car and siege car should be relatively long and large. We build a lot of cement walls under the city wall. For example, we need to restrict the opponent's rushing car. A higher cement wall is erected five meters away from the city gate. Then the rushing car will not attack the city gate." Qian Xiaoxing said.

"No, very effective." A picture suddenly appeared in Lu Shengzhong's mind. There were cement retaining walls scattered under the city wall. Hu Guo's rushing car and siege car could not pass through the cement retaining wall array. If he could not get close to the city wall, it would be easier to defend Panlong Pass.

"Well, then arrange for someone to build it immediately. Dig a large hole in the cement retaining wall and pour it down, and make some large base blocks on the bottom to prevent it from being uprooted by Hu Jun and losing its effect." Qian Xiaoxing reminded.

Lu Shengzhong slapped the city wall and said confidently: "Okay, let Hu Jun break through our cement retaining array."

"Also, for the sake of safe times, we will continue to increase the city wall. With cement, I think there will be no problem to add a few feet, and we can make a three-layer archery hole." Qian Xiaoxing pointed to the archery hole in front of him and said, "Brother Zhong, there are only more than thirty archery holes here, which means that you can only shoot thirty arrows at a time. If you build three layers, thirty people on each layer, you can shoot hundreds of arrows."

Lu Shengzhong agreed and said, "Yes, no matter how many archers there are, they will not be able to use force. With three-layer archery holes, the firepower will be much greater. In the past, it was impossible to build without cement, but now there is no problem."

"Yes, if the city wall is high, Hu is not only more difficult to attack, but our bows and arrows can also shoot farther. We also need to build some powerful crossbows, which can only be pulled by a few people, and to form different firepower attack points in the distance, middle and near." Qian Xiaoxing said.

After hearing this, Lu Shengzhong was puzzled: "There is such a big crossbow?"

"We didn't build it ourselves and collect all the skilled craftsmen from the State of Si. By the way, Brother Zhong, are there any trenchers?" Qian Xiaoxing asked.

"Take, what?" Lu Shengzhong asked in confusion.

"It's a machine that can throw the stones far away. I'll go back and draw a picture. At that time, Yang Sishi will do it immediately. Brother Zhong, look at the mountains on both sides, so don't waste it. If you use cement to make a larger platform at the top of the peak and then place a catapult, you can throw it far away, which is very shocking to the Hu army." Qian Xiaoxing suggested.

Lu Shengzhong was also excited after hearing this. As soon as Qian Xiaoxing arrived at Panlong Pass, he made many practical suggestions. He was more confident in defending Panlong Pass. When he heard the stone casting cart on the top of the peak, he smiled and said, "Okay, if you smash General Hu to death with one stone, there will be a good show."

"Haha, let's remember the flying stones from the sky for him." Qian Xiaoxing was also very excited when he thought of the wonderful scene.
