Shang Wen watched these Huns leave before returning to his tent. After returning to the tent, Shang Wen did not find Xi Lao. Look at the drawings. One is missing, and it seems that Xi Lao took it. This thing needs to be confirmed. This one can't be missing. Shang Wen has always been very protective of these confidential things. Shang Wen immediately walked out of the tent and walked towards Xi Lao's tent.

At this time, Xi Lao was making the overall frame of the bicycle, and Xi Lao was doing it with relish. While laughing happily, he watched the drawings be made. "Boy, I'm here to scare you."

"What scared me," Shang Wen said as he walked in.

"This, this is what you did." Shang Wen looked at the bicycle frame on the ground in disbelief. This is basically no different from the current one. It's just that the modern ones have been changed to metal or fiber, and this one is all made of bamboo.

Shangwen made two laps around the frame of the bike.

"Oh my God, it's a bike." Shang Wen said in disbelief.

"How?" Xi Lao said happily.

"This." Shang Wen said with a thumbs up.

"Oh my God." Shang Wen sighed again. Workmanship is not a clever word that can be described. The body is all bamboo. A beam made of bamboo poles, the frame is divided into two under a large bamboo. I don't know how to separate this. Moreover, not a single nail was seen on it. It's all that clever buckle shoots. this thing. Shang Wen has only read it in books, or in the Hanging Temple. I didn't pay attention at the time. Wait until the tour guide arrives. Shang Wencai thinks. It's not something that people can think of. Now see it for yourself. I just think. Bicycles, among the ancients, could certainly have been built. This is definitely not the wisdom that ordinary people can have. "God. God is it. Shang Wen praised again.

"I'll show you this." Xi Lao took a round wheel.

"It's the wheel." Shang Wen looked at the wheel, which was bent into a circle with bamboo. In the middle of the wheel is an axle made of wood with a very fine workmanship. Since there were no bearings, Shang Wen knew that this thing was a bit big. It's filled with butter or other oils. for lubrication. This is the bearing of antiquity. Connecting these axles are those with slender bamboo spokes. I don't know how these spokes are connected. Shang Wen took a closer look. Oh, my God. Such a coincidence. It's just a long, thin, flat round hole. As long as those spokes are inserted from the long place, the thick and long part of the back will naturally get stuck. Then the spokes twist a little. In this way, it is fixed to the rim made of bamboo. The other end is the same. The second snaps the first spoke just right. So a circle down. The whole wheel is done.

"Wonderful, wonderful." It's in the hand is too ingenious.

"Hehe, I'd like to make one out of a hollowed-out wooden wheel. But think about it. It's too heavy. So I didn't move. I can give it a try, though. Xi Lao said with some pride.

"Well, though, there should be a lap of stuff outside the rim. Otherwise, you're going to break the spokes. Shang Wen put forward some suggestions for improvement. Shang Wen's clear guidance, what is missing is rubber, and only with rubber, the bicycle will be lighter.

"This is natural. This is natural. Xi Lao said.

"But what kind of material is good for that." Shang Wen thought.

"Let's use bamboo sticks for this. This is easy to get. Just make a slightly larger set up. Use linen, or simply use bamboo strips. Rest assured, the bamboo strips I set will definitely work. Xi Lao seemed to see that Shang Wen was worried. I expressed some of my thoughts in advance.

"That's good, that's good." Shang Wen nodded repeatedly.

"Xi Lao, you are busy first. I'm going to look at something else. But you have to keep this drawing. Don't let anyone else see it. This thing is our life. Shang Wen said solemnly.

"This is understandable. The people within our craftsmen. Nature knows. Rest assured. Xi Lao nodded and said.

"Then I'll go and get busy." Shang Wen took his leave.

On the dusty Qin State galloping road. A black army is marching fast. "Take it easy." Zhao Gao called out to a captain on horseback in a big car. "Go back to Zhao Gonggong. It's been a bit more leisurely. The lieutenant said in embarrassment. Daring. You ......". "Zhao Gao, don't be embarrassed." A calm voice came out. "Wow". Zhao Gao replied respectfully. "Where?" King Qin said through the car door. "Your Majesty, you have already crossed the Yellow River." Zhao Gao said. "It's been a long walk. Then take a break! "The King of Qin has ordered." Whoa". Zhao Gao and the lieutenant replied.

Zhao Gao waved his hand. The carriage and horses immediately stopped. Zhao Gao immediately jumped out of the carriage. Personally set up the case to get off the car. Then stand aside. King Qin stepped out of the carriage. Stretch your waist. "It's so comfortable!" King Qin said loudly.

"Although the car was bumpy, the widow was able to sleep peacefully." King Qin said energetically. Suddenly, King Qin's eyes narrowed. Pointing to the dusty place in the distance, he said, "What's ahead, why is it dusty?" When Zhao Gao heard this, he was taken aback. Dusty. It's an army. This section comes to mind. Zhao Gao hurriedly blocked in front of King Qin. "Escort". Zhao Gao shouted loudly. As soon as I heard the "escort", all the Qin soldiers ran "uproar". The sword is unsheathed. Unusual nervousness for a while. At this time, a lieutenant walked up and knelt down on one knee and gave a military salute, saying, "Back to the king, in front of you is Mr. Qin's rest team, not the enemy army. King Qin listened and waved his hand to "go down." The soldiers began to evacuate and return to their original posts. Zhao Gao also left quickly. "Build a road, what kind of road?" King Qin asked. "Back to the king, according to the Malay report from the front, it is said that it is to build a highway." The lieutenant said respectfully. "Highway, what is this". King Qin muttered quietly. "Let's go, look ahead." King Qin said with a wave of his arm. "Wang ......" Zhao Gao saw King Qin's decision, and hurriedly asked the people around him to prepare in advance.

When the king of Qin came to the construction site, all the soldiers who were guarding the Qin army knelt on one knee and saluted. The Huns had been driven away from afar, and they all fell to their knees. Those who dare to stand up will be shot directly with bows and crossbows by the soldiers of the Qin army in the distance.

"Get up." King Qin waved his hand.

"Thank you, the king." The soldiers stood up.

"Do what you need to do, don't gather around me." The King of Qin gave the order.

"Whoa." King Qin continued.

"Call the guards of the construction site, the widow has something to ask." King Qin said.

"Whoa." Zhao Gao hurriedly agreed.

"My subordinates meet the king," a lieutenant saluted on one knee.

"Get up and speak." King Qin said.

"Whoa." The lieutenant clenched his fists and got up.
