Traveling through Great Qin: Father Qin Shihuang!

Therefore, when they saw Zhao Yun and Li Si appearing with the prison cart, these people gathered immediately.

"Do whatever it takes to kill Ji Bu!"

Several people looked at each other, without any hesitation, instantly drew their weapons and rushed towards the prison car.

"There are assassins!"

The people on Zhao Yun's side also reacted very quickly. The first time they saw the opponent appearing, they formed their formation.

However, Zhang Liang's subordinates had no intention of fighting them at all, and went straight to Ji Bu on the prison car.

"Whoosh! Whoosh! Whoosh!"

A series of cold arrows shot straight at Ji Bu without holding back.

"Even killing one's own people is really ruthless."

Zhao Yun stretched out his hand for a move, and the long spear was impressively in his hand. He flew up and blocked the front of the prison car. He shot down the cold arrows that came one by one.

"With this little ability, I still want to assassinate, I think too much."

Zhao Yun suddenly shouted.

"Do it, don't leave one!"

As the voice fell, dozens of disguised Jin Yiwei suddenly appeared from the crowd on the side of the road, and directly surrounded the assassins.

"No, we've been tricked!"

Seeing this scene, Zhang Liang's subordinates only reacted, but it was too late, they obviously couldn't be Jin Yiwei's opponents.

Not long after, several assassins were all arrested by Jin Yiwei.

"Bring them back to the lord. I was worried that there would be no place to arrest them. Now it's good, I sent them to my door."

These subordinates are Zhang Liang's confidantes, if they can find out something from the interrogation, it will be very useful to Zhao Che and the others.

Jin Yiwei escorted the assassins away, and Zhao Yun continued to take Ji Bu to Xianyang.

Zhang Liang had arranged such a wave of assassinations in total, but the road ahead went much smoother, without encountering any obstacles.

After bringing him to Xianyang, Zhao Yun left on his own initiative. Because of Ying Zheng's status, it was obviously impossible to meet him in person.

……

Even if the matter here was settled temporarily, after Jin Yiwei returned with those assassins, he handed it over to Yuhuatian and the others for interrogation.

On Zhao Che's side, he was busy with his own affairs, responsible for teaching Zheng Guo and Mo Sheng.

"Young master, I have always had an idea, that is, I want to make something that can act without manpower, and can be used to replace the effect of transporting materials."

Hearing what Mo Sheng said, Zhao Che couldn't help being a little surprised. Did the ancients come up with the concept of a truck so early?

"Young master, this is the blueprint I designed before. It imitates the figure of a cow and horse, and uses four legs instead of wheels. In this way, it can save a lot of effort when encountering bumpy roads."

Mo Sheng took out a blueprint and handed it to Zhao Che to explain.

"I have already designed everything about this equipment, but the biggest problem now is that I don't know how to make it move."

"Wood cows and horses?"

Zhao Che glanced at the drawing, and subconsciously blurted out.

The thing proposed by Mo Sheng is exactly the same as the famous wooden cow and horse in history, both in structure and concept.

The real wooden cow and horse have long been lost in later generations, so Zhao Che doesn't know whether the one proposed by Mo Sheng is the one made by Marquis Wu. From the point of view of the manufacturing concept, the two should be the same thing.

"So you mean, you want me to help you solve the problem of the power source?"

Zhao Che asked while holding the blueprint.

"Yes, if we can make this thing move by itself, we can save a lot of energy when transporting supplies and food in the future."

However, Zhao Che shook his head after hearing this.

The reason why wooden cows and horses are lost, in fact, apart from the troubled times of war, the most important thing is that it is not so practical.

Zhuge Liang created wooden cows and horses, entirely to solve the problem of mountainous roads in Shu, bumpy and uneven, and inconvenient transportation.

The working principle of the wooden cow and horse is to replace the previous wheels with four legs, and then use the mechanism to drive them. When transporting, the four legs can move by themselves.

And this principle, the biggest advantage is that it does not pick the road conditions, especially suitable for mountain climbing.

In the process of going uphill, the four-legged can only move in one direction. When stopping, the four-legged mechanism will automatically buckle the four-legged, so that the wooden cow and horse don't have to worry about falling off.

But when it comes to flat ground, the disadvantages of wooden cows and horses come out, because the transportation efficiency of quadrupeds is far inferior to that of wheels.

Moreover, due to the structural problems of the wooden ox and horse itself, the things that can be transported are also very limited.

Therefore, it is not without reason that the wooden cow and horse were lost later.

"Young master is really a god-man, and he can tell the principle of it just by looking at the blueprint."

"I've only seen similar designs, but this thing is really not practical."

Zhao Che shook his head and said.

"Since the young master says it's not practical, then it must be so."

Mo Sheng sighed. This thing can be said to be the result of his many years of research, and now it has been rejected outright. It must be a lie to say that he is not disappointed.

"Your idea is correct. It can only be said that because the real thing has not been manufactured, it leads to insufficient understanding of the actual situation."

"Yes, the son is right."

Mo Sheng nodded. In fact, for people like them who are engaged in inventions and creations, failure is not a rare thing.

Even if he has spent a lot of time to come up with this concept of wooden cows and horses, it is not practical if it is not practical, and this cannot be changed.

"However, this thing of yours has inspired me. It just so happens that I have researched a vehicle for transportation. You try to make it and understand some of its principles by the way."

"What kind of vehicle? Do you have a blueprint?"

Mo Sheng's eyes lit up, and the unhappiness just now was instantly forgotten.

"I'll draw the design diagram for you later, and I'll tell you the design concept of this thing first."

As Zhao Che said, he picked up a branch from one side, and drew directly on the ground.

"This thing is called a human transport tricycle. It mainly relies on the material strip to drive the gears to run, and then drives the whole car to move together."

"The back of the car is equipped with a bucket, which can be used to transport things, or take people."

"The overall structure of the car is mainly divided into three parts. The front of the car is used to control the direction, the body is used to ride and transport things, and the most important thing is the transmission structure of the car, which consists of pedals, chains and gears."

Zhao Che took the branch to write and draw, and after a while he had already drawn the outline of a tricycle.

"Young master, this tricycle is a good thing. It is much easier to use than the one I researched, but I don't know how efficient it is for transportation?"

"You will know when the real thing is manufactured, but it is not that simple to manufacture this thing. It lacks a lot of materials, and the requirements for parts are also very delicate."

"Then what should we do? If it's too difficult to manufacture, wouldn't it be difficult for these tricycles to become popular? Just making a few of them won't do much."

"Don't worry, parts and components can still be manufactured using the assembly line, and then some improvements can be made to the previous processing technology to create a special production line. As for the materials, I know where they are produced. It depends on your majesty's ability Can't get it."

Zhao Che touched his chin and said.

He said that the most important material now is rubber.
