Chapter 67: Bicycle frame

Shangwen returned to his tent after watching these Huns leave. After returning to the tent, Shang Wen did not find Xi Lao. Look at the drawings. One is missing, it seems Xi Lao took it away. This thing must be confirmed. This one cannot be missed. Shangwen has always protected these confidential things very strictly. Shang Wen immediately got out of the tent and walked towards Xi Lao's tent.

At this time, Xi Lao is making the overall frame of the bicycle, and Xi Lao is doing it with gusto. While smiling cheerfully, he looked at the drawings and did it. "Boy, I'm here to scare you."

"What frightened me?" Shang Wen walked in and said.

"This, this is what you did." Shang Wen looked at the bicycle frame placed on the ground in disbelief. This is basically the same as the current one. It's just that the modern ones are changed to metal or fiber, and this is all made of bamboo.

Shang Wen circled the bicycle frame twice.

"Oh my God, this is a bicycle." Shang Wen said in disbelief.

"How is it?" Xi Lao said happily.

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

"My God." Shang Wen sighed again. Workmanship cannot be described by a clever word. 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, no nail was seen on it. It's all the kind of clever deduction of bamboo shoots. This thing. Shangwen has only been seen in books, or in Xuankong Temple. I didn't pay attention at that time. Wait until the tour guide explains it. Shang Wen felt that. This is something that no one can think of. Now I see it with my own eyes. Just think. Bicycles, in ancient people, can definitely be made. This is definitely not the wisdom that ordinary people can have. "God. Really." Shang Wen praised again.

"Let me show you this." Elder Xi took a round wheel.

"This is a wheel." Shang Wen looked at the wheel bent into a circle with bamboo. In the middle of the wheel is a very finely crafted axle made of wood. Since there is no bearing, Shangwen knows that this thing is a bit big. It is filled with butter or other oils. For lubrication. This is an ancient bearing. Connecting to this axle are those with long and thin bamboo spokes. These spokes don't know how to connect them. Shang Wen took a closer look. Oh my goodness. Such a coincidence. It's just a slender and flat round hole. Those spokes only need to be inserted from the long place, and the thick and long place behind it will naturally get stuck. Then twist the spoke. This is fixed on the rim made of bamboo. Same on the other end. The second one just stuck the first spoke. Go in a circle like this. The whole wheel is there.

"Miao, Miao." This is too dexterous.

"Hey, I still want to make one with a hollowed out wooden wheel. But think about it. It's too heavy. So I didn't move. But I can try it." Xi Lao said proudly.

"Well, but a circle should be added to this rim. Otherwise, the spokes will be broken." Shang Wen put forward some suggestions for improvement. Shang Wen's clear guidance is that rubber is missing. Only with rubber can the bicycle be more portable.

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

"But what material is good." Shang Wen thought.

"Let's use bamboo strips for this. This is easy to do. Just make a larger set up. Use linen cloth, or simply use bamboo strips. Don't worry, the bamboo strips I set will work well." Xi Lao seems It can be seen that Shang Wen is the same worried. I said some of my opinions in advance.

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

"Elder Xi, you are busy first. I'll look at other things. But you have to keep this blueprint. You can't let other people see it. This thing is our life." Shang Wen said seriously.

"This naturally understands. People among our craftsmen. Naturally know. Don't worry." Xi Lao nodded and said.

"Then I'll be busy." Shang Wen bid farewell.

On the dusty Qin State's Chi Road. A black army is advancing quickly. "You stay a little longer." Zhao Gao called to a captain who was riding a horse from a cart. "Go back to Grandpa Zhao. This has already taken a while." The captain said embarrassingly. "Bold. You...". "Zhao Gao, don't be embarrassed." A calm voice came out. "Here". Zhao Gao answered respectfully. "Where is it?" King Qin said through the car door. "Your Majesty, you have already passed the Yellow River." Zhao Gao said. "The walk is long enough. Then take a break!" King Qin ordered. "Here". Zhao Gao and the school lieutenant replied.

Zhao Gao waved his hand. The carriage stopped immediately. Zhao Gao immediately jumped out of the carriage. Personally set up the case board for getting off the car. Then stand aside. King Qin got out of the carriage. Stretch out. "It's so comfortable!" King Qin said loudly.

"Although the car is bumpy, the widow can sleep peacefully." King Qin said vigorously. Suddenly King Qin narrowed his eyes. Pointing to the dusty place in the distance, he said, "What's up ahead, why is the dust flying?" Zhao Gao was shocked when he heard it. dusty. Could it be the army. Think of this section. Zhao Gao quickly stood in front of King Qin. "Guardian". Zhao Gao shouted loudly. As soon as I heard the "escort" all the soldiers of the Qin Army "crash" running. The sword came out of its sheath. Suddenly nervous. At this time, a school lieutenant walked up to one knee and gave a military salute and said, "Return to the king, ahead of him is Mr. Qin's off-road team, not an enemy army." King Qin listened and waved to "Go down." "Here" the soldiers began to withdraw and return to their original positions. Zhao Gao also left quickly. "Building roads, what roads?" King Qin asked. "Back to the king, according to the report from the front, it is said that the highway is to be built." The lieutenant said respectfully. "Highway, what is this". King Qin whispered. "Go, look ahead." King Qin said with a wave of his big arm. "Wang..." Zhao Gao saw King Qin's decision, and quickly asked the people around him to prepare in advance.

When King Qin came to the construction site, all the soldiers guarding the Qin Army kneeled on one knee to salute. The Huns had been driven away from a distance, and they all knelt to the ground. Those who dare to stand up, the soldiers of the Qin Army in the distance will shoot them directly with crossbows.

"Get up all," King Qin waved his hand.

"Come on, King Xie." The soldiers stood up.

"What should I do? Don't surround me." King Qin issued an order.

"Here." King Qin continued.

"Call the guard at the construction site to come over, and the widow has something to ask." King Qin said.

"Here." Zhao Gao quickly agreed.

"Subordinates meet the king" a school lieutenant bowed on one knee and saluted.

"Get up and talk." King Qin said.

"Here." Xiao Wei clasped his fists and stood up.
