At present, the Hu army has no other movement except blocking the business road... Qian Xiaoxing also took advantage of this free time to retake the Si State's economy.

The most important thing to do at present is to build a dam. The Hu army in Si State has captured about 1,200 prisoners. These young and strong men are very good laborers. Qian Xiaoxing ordered him to start building a dam on the stream on the side of the Yimu tribe. The stream is about 20 meters wide and the river is not deep. One thousand and two hundred laborers mine rocks while digging rivers to build dams. The drop of the upstream and downstream of the river is quite large. Qian Xiaoxing estimated that it would take at least ten meters of dams. Anyway, labor is free, and there are no village tribes around the river, so they should build as high as possible.

Another thing is the operation of the arsenal. At present, the arsenal can only build some simple weapons, such as feather arrow spear, exquisite props and armor, etc., which are all made without technology or raw materials.

However, based on current resources, Qian Xiaoxing developed many practical weapons. I remember that the last time I ambushed Hu Jun on the Black Dragon Road, the soldiers did not even have weapons because it was inconvenient to carry the refining tank. So many people were sacrificed later. With this lesson, Qian Xiaoxing asked the kiln factory to make the oil tank into a rectangular shape the size of a brick, and then made a cloth bag with burning magazines tied to his chest. In this way, the incendiary bomb can be easily carried.

Qian Xiaoxing also remembered modern flamethrowers, but in ancient times, it was troublesome to fill compressed air. Qian Xiaoxing developed a high-pressure water gun, but the utensils were large and inconvenient to carry, so he made a car. There was a box on the car that contained oil refining, and there was a down-pressure lever on the box. Pressing the lever downwards and water could be sprayed out.

After testing, such a water gun can spray a distance of more than 20 meters. After changing into tinder oil, he made an oil lamp under the water spray port and lighted a small fire. When the oil was sprayed out, it immediately became a line of fire and flew out. It was quite powerful. More than ten such cars were made, and Qian Xiaoxing named the car Pili Chariot.

The last invention is a sniper bow. With a telescope and a powerful crossbow, you can form a sniper bow. As a sniper bow, what you need is a long range and high stability.

Currently, the three stone bow that can be pulled by hand has an effective range of only 40 or 50 meters. It is very difficult to accurately hit a target that is 40 meters away. A good archer like Lu Shengzhong can only hit a target of the same size as a human at a position of 30 meters.

In order to increase the range, the elasticity of the crossbow's bow arm must be increased, but the result of this is that it is difficult for a single person to pull it open. Qian Xiaoxing thought of the gear set and made several gears of inconsistent sizes. After constructing it as a gear set, he can slowly hang the bow string on the machine bracket by shaking it with a shaking handle. Such a bow can shoot 200 meters away. After adding a scope, the effective attack distance is 150 meters, and the distance within 100 meters can easily hit the target of the size of a human head.

After doing it, Qian Xiaoxing tested a shot. Lu Shengzhong saw that Qian Xiaoxing had never practiced archery skills and could hit a target a hundred meters away. He was immediately speechless when he was amazed. With this sniper bow, anyone could easily hit the target.

It was just because of the structural difficulties and the manufacturing was very complicated. I only made two of them at the moment. Qian Xiaoxing was selfishly assigned to his own guard company and assigned two soldiers who were already superb archery skills.

Qian Xiaoxing looked at the bronze long sword, and it was easy to break. He could only make it more than one meter long in craftsmanship. It would be great if there was a steel knife. I remember that I asked Xu Liang to find the iron ore area a long time ago, so I asked someone to call Xu Liang from Yingwang Village. After Xu Liang called, there was good news. The iron ore area was found, but the location was not good. It was on the mountain on the side of the road leading to the Yimu clan. If it was to mine on a large scale, there would be no road.

Qian Xiaoxing was helpless after hearing this. It seemed that only after the dam was built could it be mined. Xu Liang took Qian Xiaoxing to the outside of the palace, opened the layers of quilts in the carriage, took out something for Qian Xiaoxing to show.

Qian Xiaoxing saw that it was a concave mirror, as big as a washbasin, and the mirror surface was very bright, so he remembered that this thing was developed by Xu Liang himself and used as a light signal light.

Qian Xiaoxing immediately called Xie Boyi and told him how to use this thing, and then asked him to test it for a short distance first, so after the signal was accurately transmitted, the distance was widened for testing.

A few days later, a signal transmission station from Guandu to Panlong Pass was established. The tall signal tower was built between the two places, and the light signals reflected by the concave mirror were transmitted between the two places, greatly accelerating the transmission of intelligence.

Yi Hongyue lived in Guandu for a long time, because she was worried about the affairs of the Yi mother clan. Although she was reluctant to leave, she still had to go back. Before leaving, Si Wang, Si Yingying and others came to see her off, and Bi Yao also said goodbye to Lu Shengzhong reluctantly.

Yi Hongyue held Qian Xiaoxing's hand, her eyes were as bright as autumn water, and she said reluctantly: "Xingxing, you must come to see me when you have time."

Qian Xiaoxing nodded seriously. Seeing Yi Hongyue's eyes full of love, he replied firmly: "Don't worry, I will definitely come when the dam is built."

Yi Hongyue reluctantly threw herself into Qian Xiaoxing's arms, hugged her tightly for a while, and whispered in Qian Xiaoxing's ear: "Xingxing, you are going to be a father."

"Really!" Qian Xiaoxing pushed Yi Hongyue away, stared at her face and looked carefully. As he confirmed the information, Yi Hongyue lowered her head shyly and replied softly: "You have worked so hard, of course you will get something for you."

Qian Xiaoxing immediately lowered his head and paced back and forth, nervously not knowing what to do. Although he knew that he would come this day, he felt that he was not mentally prepared when he really came. The word dad seemed very far away to him, and he murmured: "I want to be a dad, I want to be a dad..."

When Si Wang, Si Yingying and others heard that when Qian Xiaoxing looked nervous, they all came to congratulate him with a smile.

Qian Xiaoxing came to Yi Hongyue, looked at Yi Hongyue's belly, and thought of the baby inside, and couldn't stop smiling. Seeing him kneeling down on one leg, he pressed his ear against Yi Hongyue's belly, he heard it. Yi Hongyue smiled and said, "I'm still young, I can't hear it."

Qian Xiaoxing stood up embarrassedly and said, "Hongyue, you might as well stay in Guandu."

Yi Hongyue shook her head and said, "I don't want to do it, but I am the patriarch of the Yimu clan and I have to go back. Don't worry, I will take good care of myself and our baby."

Speaking of this, although Qian Xiaoxing was extremely reluctant, he could only let Yi Hongyue go back first and arranged for people to escort along the way. Yi Hongyue and Bi Yao set off back.

——————————————

Time turned to mid-June, and Hu Jun from Longzhan City had been blocking the business road for nearly a month. Qian Xiaoxing looked at the warehouse of the Qian Group in Guandu that was full of various goods, so he shook his head helplessly. If he did not take action, the factory seemed to be shutting down.

The company commander Xiong Yitan and deputy company commander Hu Suoyuan were in a row and followed Qian Xiaoxing tightly. Seeing Qian Xiaoxing walk out of the warehouse, the two of them immediately followed.

Qian Xiaoxing ordered: "Call the guard company immediately and go with me to investigate the situation in Xialongzhan City."

Hu Suoyuan immediately took the order and left. After a while, more than 30 guards soldiers gathered in place. Qian Xiaoxing took them on horseback and ran to Panlong Pass. When he arrived at Panlong Pass and told Lu Shengzhong, Lu Shengzhong was worried about Qian Xiaoxing and wanted to go with him. Qian Xiaoxing had no choice but to take him and everyone rode his horse to Longzhan City.

Along the way, Qian Xiaoxing pulled the horse rein and asked Lu Shengzhong: "Brother Zhong, I remember that the road to Hu Country is through Longzhan City, but the road to Lin Country is not through Longzhan City, so why is the business road blocked?"

Lu Shengzhong sat on the saddle and replied: "The Hu army also sent troops to garrison on the way to Linguo, with about 2,000 troops."

"Oh, I'm stationed outside the city? Only 2,000 people are not afraid of us attacking?" Qian Xiaoxing had some thoughts when he heard this.

After hearing this, Lu Shengzhong shook his head and replied, "The Hu army now has more troops than us. Even if we can kill two thousand people by sneak attack, we will suffer a lot of losses. In addition, if our troops leave Panlong Pass and are surrounded by Hu army, the consequences will be very serious."

Qian Xiaoxing nodded. It was indeed too risky to leave Panlong Pass to attack sneakily. Moreover, even if the sneak attack was successful, the Hu army could still send troops to garrison when the Si army retreated, which would not solve the problem at all.

After riding for a while, Xiong Yitan, who knew this place well, said, "Chief of Staff, two miles ahead is the fork to Lin Country."

"Where is the Hu army guarding?" Qian Xiaoxing asked.

"Well, the fork in the road has passed, and it is about three miles away." Xiong Yitan replied.

Qian Xiaoxing thought for a moment when he heard this and said, "This is strange. Why don't you guard this fork in the road? You can guard two roads in this way."

After hearing this, Lu Shengzhong thought for a while and analyzed: "The current location of Hu Jun guarding is relatively close to Longzhan City, about one mile away. If you guard this fork, it is about three miles away, maybe it is to make it easier to rescue."

"It seems that Hu Jun is not stupid either. He is afraid that we will attack and build the camp near Longzhan City. It shouldn't be what Hu Baojin thought about." Qian Xiaoxing said with a smile.
