After the whole sect traveled to ancient times, I led the rebellion

There is murderous intent!

An Yin instantly got rid of her dilemma. When she opened her eyes, she saw Mu Qing looking at her with his arms folded and a smile on his face.

An Yin glanced at Mu Qing, who was smiling with narrowed eyes, and suddenly got goose bumps all over her body.

According to the stories she had collected from reading the world of cultivation, why did the little junior sister's smile carry a sinister and cunning aura?

How come it looks so much like...

An Yin glanced at Mu Qing again, but for a moment she couldn't remember which character in the storybook he looked like.

Until Mu Qing's eyes showed three parts of indifference, three parts of smiles and one part of ill intentions and he said:

"Senior Sister, everyone in our Sword Sect is a genius, and you are the genius among geniuses."

Mu Qing came up to An Yin and quickly pulled her to sit down, then his face was filled with smiles again:

"I want to build a bicycle and I need help urgently."

When An Yin heard Mu Qing's last request, her eyes became completely clear and she looked at Mu Qing with a complicated expression.

She finally knew who the little junior sister’s smile looked like.

It was particularly similar to the standard smile of the villains in the novels that An Yin had read, even the curve of the lips was almost exactly the same.

An Yin: Junior sister, please stop smiling, it's too evil.

Life is not easy, An Yin sighed.

What else can she do when her junior sister needs her? An Yin only has this junior sister, so of course she has to pamper her.

But it seemed like she hadn't eaten the food cooked by her junior sister for a long time. An Yin licked her lips:

"You can, but I want to eat braised pork tonight."

"okay."

After receiving the response, An Yin quickly agreed to Mu Qing's request. Needless to say, Shen Moyan had already made clear arrangements for him.

The parts of a bicycle have to be built step by step, which is time-consuming and laborious.

Mu Qing looked at An Yin:

"I'll leave the welding to you, Senior Sister. This level is not difficult for you, as long as you can melt the metal."

"Set it on fire and then melt it?"

"Yes."

An Yin was a little confused at first, until she started experimenting.

Mu Qing looked at the perfectly welded metal and could only say that she was worthy of being the senior sister with a strong talent for cultivating immortals, and her welding attributes were maxed out.

Since both of them were there, Mu Qing took out the theoretical diagram of the bicycle.

The basic form of a modern bicycle consists of a triangular frame, pedals, chain and brakes.

The first thing is the frame. This is not a difficult problem to solve. It might be possible to use wood or bamboo instead before steel appeared.

Modern bicycle materials are mostly steel, aluminum alloy, titanium alloy, and carbon fiber, which are materials that combine toughness, hardness, and lightness.

Since Anping has both steel and iron, the frame is naturally made of steel, and the same goes for the pedals and brakes.

For the design of this step, Mu Qing introduced the design drawings of the Meihua C60 frame.

The frame of the Meihua C60 uses the LUG sleeve technology that the company is proud of in its steel frame era. The carbon fiber is made into a sleeve shape to strengthen the strength of the connections between the tubes.

Shen Moyan will make the parts, and then An Yin can weld and reinforce the joints of the sleeve.

Next comes the chain needed for transmission.

Modern chains consist of outer plates, inner plates, shafts and rollers.

This step requires Shen Moyan to press out a bunch of steel sheets first, and then buckle them together. The shapes and sizes cannot differ too much.

The chain is roughly composed of a large iron ring inside a small iron ring, with a circle of steel balls in the middle.

The principle is very simple.

Mu Qing had many impressions of this when he was studying high school physics.

Rolling friction is less than sliding friction.

The principle seems simple, but it has very high requirements for metal smelting and processing, so Shen Moyan needs to handle it.

However, if Mu Qing wanted, he could actually replace the chain with the wheels of a carriage.

Carriages have always used sliding bearings.

Sliding bearings are actually just a stick that is inserted directly into the hole in the center of the wheel, and then supported at both ends with metal or wood to allow the wheel to run.

To ensure smooth rotation, apply a thick layer of oil in the hole.

A bicycle requires a lot of parts.

Mu Qing also asked Mo's disciples to help make a batch.

If mass production is to be carried out in the future, Shen Moyan alone will not be enough.

Now Mu Qing will first experiment with the bicycle, and then gradually promote it based on the experience.

As Shen Moyan was making the steel sheets, his control over his spiritual power became more and more proficient. Mu Qing even wondered if Shen Moyan could still change the arrangement of atoms with his bare hands.

But her speculation did not last long.

The first bicycle built by Shen Moyan and An Yin appeared in Anping seven days later.

With bicycles, even though bicycles of this level may not be as good as horses at the moment, they are obviously much better than walking.

Not only does it save effort, but you don't have to prepare fodder.

The carriage horses needed rest and food.

Feeding grass alone is a huge expense.

Bicycles don’t exist.

As long as the technology is mature, it can be mass-produced.

Apart from the purchase price, all you need for a bicycle is daily maintenance.

In the eyes of others, steel may be more difficult to obtain than horses, but in Anping, the amount of steel that Mu Qing practices gradually increases, and soon there will be as much as iron.

At that time, Shen Moyan can be asked to build the machine tool first.

Apart from some labor costs, everything else is made from local materials and is low-cost.

In short, we can make a few bicycles now. It will be much more convenient to deliver messages in daily life with a new means of transportation.

After all, the official roads are now all cement roads, and the speed of bicycles will be much faster than on dirt roads.

Mu Qing did not plan to use the first bicycle himself, but instead invited Li Min over first.

"Mr. Li."

"Here I am, here I am. They called me from the clinic so early in the morning. Did they develop penicillin?"

Li Min guessed when he saw the smile on Mu Qing's face.

Li Min was very concerned about the research progress of penicillin and would visit the biological laboratory almost every three days.

Mu Qing listened to Li Min's words and shook his head:

"No."

"That's not it. I'll leave first. The clinic is busy."

Li Min turned around and was about to leave, but Mu Qing stopped him with a smile:

"It's not penicillin, but it's something that might interest you."

Mu Qing's firm tone stopped Li Min in his tracks. He looked around curiously, and finally his eyes stopped on something covered with a piece of cloth in front of him.

"This is?"

Li Min looked at the bicycle covered with cloth behind Mu Qing and changed his mind about leaving.

Mu Qing always has a lot of ideas.

After hearing what she said, Li Min was really interested.

Mu Qing not only called Li Min, but also Mu Wu and Mu Shu.

Facing the bicycle that had taken seven days of effort to make, Mu Qing smiled slightly, then lifted the cloth covering his back.

The cloth was lifted, revealing before the three people a new and strange object they had never seen before.
