The Red Era, the Opening University Speech

Chapter 63: The map is out! Technology! (Please read it later)
"But..." Zhang Kai and Li Jian were not stupid. Even if they didn't realize it at the time, they came to their senses now.

But the two of them gritted their teeth and didn't eat meat for a month or two, and they would be able to get through it. But Li Mu really couldn't do it!
Li Mu looked at the concerned looks in their eyes and couldn't help but feel moved.

In fact, he is not really poor now.

I just can't say it.

Both the single crystal furnace and the ultra-thin diamond wheel cutting machine are top secret projects and no information can be disclosed.

Li Mu thought about it and said, "Don't worry, we may not lose."

"Do you have any other good ideas?" Zhang Kai and Li Jian's eyes lit up at the same time. If they competed in skills, they would definitely not be able to beat the well-trained Xue Qing.

Li Mu smiled and said, "No hurry, let's go sign up first and see the specific content of the competition."

"Okay." Zhang Kai and Li Jian felt like they were being scratched by a cat, but since Li Mu didn't say anything, they had to suppress their curiosity for the time being.

The three of them went to the registration office to line up.

When I got to Li Mu, I asked the student in charge of registration: "Hello, classmate, do you know where our competition will be held?"

"It's in the suburbs outside Kyoto, in the Beihe area. It's all in this brochure. You can check it out yourself." The classmate in charge of registration handed Li Mu a folded paper brochure.

Letterhead on the paper: Instructions for cycling competition participants.

Below the rules is an introduction to the competition time and venue.

The competition will be held in three days, and the competition venue is 3 kilometers of city roads, 8 kilometers of up and down slopes, plus 3 kilometers of country roads, a total of 5 kilometers round trip.

"Li Mu, you've been looking at the manual for a long time, so give me some ideas!" Zhang Kai said anxiously when he saw Li Mu staring at the manual for a long time without finishing his words.

This manual only has a few dozen words and a picture, and it took me a long time to read it.

Li Mu no longer kept the secret and said, "I am 5% sure now, but whether it will work depends on whether you two can help me find bicycle parts."

"You want to modify the bicycle?" Zhang Kai was stunned for a moment, then reacted and asked in surprise.

"Yes, it's not written in the manual that we can't modify the bicycle." Li Mu smiled and raised the manual.

Bicycles of this era were made entirely of steel to carry loads, with a load-bearing crossbeam in the middle, designed to be durable and practical.

But correspondingly, bicycles also sacrifice a lot of things.

"Bicycle parts are not difficult to find, but is it really possible?" Zhang Kai hesitated.

In his impression, domestic bicycles have almost reached the best in every aspect, and there is no room for improvement at all.

"You go look for it first, and then come back to my dormitory. I will show you the design drawings and you will understand." Li Mu smiled mysteriously.

This time he didn't need to ask Ask for help.

He knows everything about mountain biking.

As a hobbyist, when he became fascinated with cycling, Li Muke carefully studied everything from structure to materials.

……

Return to the dormitory.

Li Mu relied on his memory and spent about half an hour to reproduce the design of the mountain bike.

Just as I stopped writing, Zhang Kai and Li Jian pushed the door open in a hurry. They each picked up the cup of water on the table and took a big gulp of water.

"Can you find the accessories?" Li Mu asked.

Zhang Kai gulped down the water and said, "I found out there is a recycling station near the school."

"There is just one problem. It may not be that easy for us to take it out."

"Why don't we buy some cigarettes and alcohol and go over there, maybe the old man will agree."

Li Mu was a little speechless. How could you give a gift in broad daylight? You dare to give it to others but they dare not accept it. Li Mu stood up and said, "Let's go and take a look first. Let's go."

There are only 3 days left before the competition, time waits for no one.

Zhang Kai looked at the manuscript paper on Li Mu's desk and asked, "Don't worry, this is the design you drew. It doesn't seem to be anything special."

"Hey, wait, what's that thing you put next to the wheel?"

He suddenly discovered that there was an extra part on the bicycle, which seemed to be quite large.

"There is also a back seat, why is it gone?" Li Jian looked at the drawing and found something wrong.

"The renovation project is not small. We must hurry up and talk as we go." Li Mu continued as he led the two of them out:

"I modified this bicycle to reduce some unnecessary designs, which can reduce weight and effectively increase the speed of the bicycle."

"Of course, the probability of winning the game with just this is still not high."

As he spoke, Li Mu pulled out two more design drawings from under the mountain bike drawings:

"This is the transmission and micro motor assist device I designed. With these two things, we have at least an 80% chance of winning."

Zhang Kai was holding the blueprint of a micro motor. After taking a look at it, he quickly understood that Li Mu was planning to use the principle of converting electrical energy into energy to speed up the bicycle.

However, considering the size of the micro motor assist device, the battery life it can carry will not exceed twenty minutes.

A game would take at least one day, and twenty minutes would definitely not be enough.

In order to ensure sufficient power, they have to carry a large number of batteries to the competition.

Zhang Kai couldn't help but wonder, "Can these two things really help us win the game?"

"How long can such a small micro motor assist last? And with this transmission, can it speed up?"

Li Mu smiled and explained, "The micro motor assist is mainly used to save effort when going uphill. I have carefully calculated that this number of batteries is enough for us to complete the steep slope section of the race."

"As for the transmission, it is a device that can adapt to different road conditions by changing the size of the gear plate."

"Take going uphill or downhill as an example. When going uphill, you can switch to a smaller gear through the transmission and pedal, which greatly reduces the physical exertion."

"Everyone knows how to ride on a flat road, but riding fast uphill is the real fast, do you understand?"

Zhang Kai and Li Jian did not speak, but picked up the drawings from time to time, seeming to be seriously considering the feasibility of this method.

"But the micro motor auxiliary device and the transmission may be difficult for us to get!" Zhang Kai put down the drawings and looked at them. He didn't understand them and could only choose to trust Li Mu.

When it comes to production, it is another difficult problem.

It's not that convenient these days. You can buy any tool you want.

Li Mu smiled and said, "Don't worry, my uncle works in a glass factory. We can just ask their master fitter to fix it."

Li Mu remembered that the last time Li Jun helped to make an air fryer, the finished micro motor was very good and perfectly met the needs of a crude version of the fryer.

I really have to admire the strength of the seventh-level fitter.

……

After briefly finalizing the plan for the bicycles on the way, the three of them arrived at the material recycling station.

The old man guarding the door was talking to a young man in a factory uniform.

After they walked in, before Zhang Kai could even open his mouth, Li Jian couldn't help but call out, "Uncle, why are you here?"

Li Mu was originally thinking about whether he could find some substitute materials to save costs, but when he looked up after hearing this, he discovered that the man was actually the factory youth who played basketball with them last time.
