"I wonder what major changes will happen this time. Judging from the situation, the thing that Liyue's elites are being mobilized to research must be very important."

"Nonsense, if it's not important, you wouldn't ask so many researchers to deal with it together, right?"

The newly built auditorium at Yujingtai.

There were more than 200 buses parked outside, and many military vehicles and personnel were maintaining order. After a year of expedited renovation, the main buildings of Yujing Terrace, the face of Liyue, had been completed.

The auditorium was already packed with people, and the corridors were full of people, all waiting for Lin Zixuan's arrival. Some researchers who were far away and could not come opened their exclusive conference screens in their offices.

Suddenly, a familiar figure appeared on the podium.

"Long time no see, Liyue's best researchers.

Seven years have passed in a flash, and many people have grown beards, formed families, and possessed the symbols of strength. I would like to thank you for your hard work in researching and making Liyue the envy of the other six nations.

This time we have gathered everyone here for a very small matter, but this matter will have a very huge impact on the future.

Two years ago I had already made clear the goal of our scientific researchers, which was to pursue a path of sustainable development and to be pragmatic.

After all, you all know that if what we research pollutes the land and water veins, it will take thousands of years to restore them to their original state, which will bring disaster to our future generations.

But there is one thing that you use a lot, and the entire Liyue uses a lot. They are very inconspicuous, but very important things. Not only are they harmful to the human body, but they also cause the greatest harm to the environment. Can you guess what it is? "

The researchers in the auditorium began to discuss.

"Well, I heard someone guessed it. That's the current rubber product.

It is very inconspicuous, but its usage can be said to develop over time and become a giant industry. Rubber gloves, various seals, tires, you can see it almost everywhere.

This convenient and practical rubber product also faces huge disadvantages. It can be said that it is very difficult to handle, which is contrary to the sustainable development of our Liyue.

You should all have seen that our Liyue crystal cars use rubber tires that are added with carbon black. After using these tires for a period of time, you will find that the deep grooves on the tires have become shallower and the original wheel diameter has shrunk.

So where did all this missing rubber go?"

The mahogany-framed screen on the wall behind Lin Zixuan began playing images.

on the screen.

On a road in Liyue Harbor, a crystal car sped past, raising a large amount of dust. In the dust, tiny pieces of rubber worn off the tires were moving with the dust.

An ordinary young man who was jogging on the roadside inhaled the black rubber with carbon black into his lungs. Many years later, the young man became a middle-aged man. He exercised regularly and had no bad habits. He could be considered to be very health-conscious. However, he developed symptoms such as coughing, expectoration, and chest pain.

This situation left Bubulu completely puzzled. Apart from exercising every day, he followed his doctor's instructions on eating, drinking and sleeping.

However, he passed away before he was 40. His family felt that something was wrong, but they took Bubulu's prescription to other doctors, but no one found anything wrong with it. They were all mild medicines. Logically, his condition should not have gotten worse.

After negotiating with the family, Bubulu dissected the middle-aged man despite the customs. He then found countless black lumps in his lungs. After sending them to the Liyue Research Institute for analysis, they found that the composition of these black lumps was rubber. Bubulu called this condition pneumoconiosis, or pneumoconiosis for short.

People were horrified to discover that the dust on the road contained a large amount of rubber.

This incident caused people to remove all rubber wheels and replace them with ironwood and iron wheels. All rubber products were sent to be incinerated.

A large amount of rubber was burned for ten days and ten nights. People were horrified to find that not only was Liyue Harbor filled with a strange smell, but the entire sky was blackened, and the birds that were flying well fell from the sky and died for no reason.

People asked the immortals for help and made it rain. However, something even more terrifying happened. All the vegetation in Liyue Harbor was eroded by the rainstorm. All the plants, flowers and birds died. Even human skin was corroded when it came into contact with the rain. This disaster was later called acid rain.

After the boycott of rubber began, people discovered that these small gaskets and sealing rubbers actually played such an important role. Without these rubbers, the costs of countless industries in Liyue would have increased by almost two times or even a hundred times.

The original 200-morar rubber tube had to be replaced with a 2000-morar metal tube, and a new sealing method had to be used to prevent water leakage at the joints.

Finally, research by the medical department of Liyue Research Institute shows that the human body has a self-cleaning function, and trace amounts of ingestion can be automatically excreted from the body without causing pneumoconiosis.

The screen playback is completed.

The entire auditorium was very quiet, and everyone was stunned to see the consequences. Some people had recovered and knew that what was going to be said next must be related to rubber.

“I believe many people have remembered what I said back then.

[This technology is only suitable for use in the initial stage and will be abandoned in the later stage. ]

These images are the real reason why I threw it away.

But why didn't I order a halt to production? You should all know that it's because it's so convenient and easy to use. It's indispensable for all kinds of large and small devices.

As you know, ironworks can make alloys of various properties. So, can rubber be made into a new type of rubber that is non-toxic and easy to process through some synthesis, alchemy, etc.?

I was very sad to see the financial allocation for the Rubber Research Institute. The annual allocation was only 2000 million Mora, not even one percent of the iron and steel plant research institute.

Since you have received so much research funding, then there should be no problem in assisting the Rubber Research Institute in developing new types of rubber, right?

Now, let’s start the assignment. The first group…”

The first wailing sound in many years was heard in the auditorium.

Since this meeting was not a secret, no gag order was issued, and the content of the meeting quickly spread throughout the continent of Teyvat. The people of Winterfell reacted most strongly, after all, Winterfell used Kanreya's technology, and the thick black smoke rising from the factory and the problems that had already occurred told their future.

In May, the Tour of Liyue cycling race was officially held.

With the help of the Seven Stars, the event was very lively. Lin Zixuan also showed up and then ran away. A white-haired girl in Mondstadt, with the help of Diluk and others, learned to ride a bicycle crookedly. Every time she fell, she couldn't help but curse the green bard who had been missing for a long time.

At the end of May, when Liyue had mobilized the whole country and used all its human, financial and material resources, the researchers from the Rubber Research Department placed a piece of milky white rubber in front of Lin Zixuan.

Its name is: Slime Rubber.

Chapter 247 Innovation Brought by Slime Rubber

This piece of slime rubber, made with the wisdom of the entire Liyue, has properties that almost crush ordinary rubber.

The most common milky white rubber can be used as a gasket, and its lifespan is estimated to be longer than that of ordinary rubber.

And after injecting elemental power during the production process, new characteristics will appear.

Infused with fire elements, slime rubber is extremely resistant to high temperatures.

Infused with water elements, slime rubber is unusually soft.

Infused with lightning elements, slime rubber is extremely insulating and can withstand a higher voltage limit.

Infused with ice elements, slime rubber is extremely resistant to low temperatures.

Infused with wind elements, slime rubber can be abnormally stretched and thinned.

Infused with rock elements, slime rubber is extremely hard and wear-resistant.

This is just a single property. The most important thing is that when testing this slime rubber, a composite property was discovered.

Injecting water and rock elements at the same time creates a new material that is both soft and wear-resistant.

Lin Zixuan was also stunned when he saw this long list of reports. He didn't expect that there would be so many different characteristics. I'm afraid that there will be a lot of people studying slime rubber in the future.

This slime rubber can be easily recycled after it is scrapped. It does not contain carbon black or sulfur, and can even be incinerated without any major problems.

Not to mention that the alchemy department also provides a decomposition liquid, which can decompose the slime rubber into two layers, the rubber layer and the original pulp layer after standing for a period of time. Of course, this technology is not yet mature and needs time to study.

This should be a special item that can only appear in the continent of Teyvat with elemental power, right? The manufacturing process of pneumatic tires is completely different from that of solid tires. It seems that we need to intervene and let these researchers upgrade and iterate later.

"It's very well done. I am very satisfied with this slime rubber. But there is still a big problem, which cannot be ignored."

"Master Xuan, what's the big problem?" A question mark appeared over the heads of a group of people.

"It's a problem of raw materials. Although there are many elemental creatures like slimes in the outside world, once we start using this slime rubber on a large scale, the slimes in the outside world will probably be killed to extinction."

"Yes, the price of these slime pulps is quite expensive. After all, they are collected by adventurers or the Thousand Rock Army when they go out on missions, and then brought back for refining." After Lin Zixuan mentioned this, A Xiang and others also discovered the problem.

"I'll go think of a solution first. You guys should sort out the new formula for these slime rubbers."

June st.

Television stations and newspapers began to publicize the successful development of the new slime rubber. Two new policies were also announced.

The companies that have purchased the previous rubber technology were ordered to stop the production of the old version of rubber, and the existing production was not affected. A ban on the production of the old version of rubber technology was issued. The General Affairs Department re-provided the new slime rubber technology to these companies.

The second point also shocked many people. After the nectar of the lily flower was kept in captivity, slimes also became new members of the captive breeding. The captive breeding of water slimes will become a new industry.

"Ahhh! I can't stand this anymore."

A young man in green adventurer clothes threw his backpack to the ground. Everyone saw how excited he was and understood what was going on.

These adventurers are out there, running around, risking their lives. Originally, these slime condensates could be sold at a good price, but once Liyue chooses to raise them, how low will the price be?

These slime gels are not like nectar. There is a difference between farmed and wild ones. The price will vary a lot because of the quality.

"He seems to be a new adventurer. He goes out for ten days or half a month, but he doesn't make as much as those adventurers who deliver food and goods."

"Those treasure chests are left outside and no one has opened them. I opened them a lot the last time I went out, and all I got was cabbage and some ordinary iron ore, and the quantity was very small. The cabbage is fine for one or two meals, but if you eat it every day, you'll get tired of it."

"The main reason is that since Liyue started using these alloys and fairy equipment, the price of weapon embryos has plummeted. Ten years ago, they could be sold for 10 billion Mora. Now the price has become around 1000 million Mora, and it depends on the quality of the embryos."

"The prices of those upgraded immortal equipment on the black market are sky-high. Liyue can now mass-produce purple and gold weapons, so the prices of these embryos have naturally dropped. Mondstadt is close to us, so the prices of these embryos are most affected.

If I want to sell it to Xumi Fontaine, which is far away, I don’t know how many waves of treasure-stealing groups I will encounter. I heard that the Gilded Brigade in Xumi are the ones who kill without blinking an eye. Even if I sell the embryo, I don’t know if I can return to Liyue alive. "

"Now, adventurers in Liyue can only venture into secret realms. Steambird News has counted the rewards of those who have spent more than a month to complete the 99th level of secret realms, and it is not low. But if you don't have the strength, it would be the least of your life to come out disabled after entering."

"Then again, do you dare to raise these slimes?"

"Why not? What's wrong with a palm-sized slime? Besides, a water-attributed slime can only spit out a few bubbles. If it's a slime with three attributes, I wouldn't dare to raise it. It's too easy for something to go wrong."

The people of Liyue were discussing these two new policies.

In a rubber factory owned by Ningguang, countless people were staring at the special machine combining wood and iron in front of them, watching it combining several types of slime rubber together step by step.

Wind element slime rubber airtight layer, fire element slime rubber high temperature resistant layer, fiber cord layer, side steel ring layer of water and rock mixed slime rubber, and outer layer of rock element slime rubber.

Finally, it was sent to a furnace for final shaping. An hour later, the special machine was turned on and four tires that were almost the same as the Blue Star were produced.

The only difference is probably the color, which is an earthy yellow that reflects the power of rock element.

"Is it done?" Ningguang walked forward and picked up the slightly hot tire. She pressed it and found it was a little hard.

"Well, it has been successfully produced."

"Shouldn't it be like the balloons at the Mondstadt Windblown Festival, with a place to blow air into it and then tied up with a rope? This is empty..." Ningguang pointed to the middle of the tire.

"This requires a wheel rim that is different from the solid tire." Lin Zixuan took out four special wheel rims that were customized by the iron smelting factory and installed the tires with the help of another manual machine.

Question marks popped up in the heads of the onlookers. This must be a leak, right?

Lin Zixuan took out a T-shaped object and began to squat quickly to inflate the tire. You guessed it right, this is an air pump. There is no such thing as an air pump in Liyue yet, let alone an air pump.

Suddenly, there was a loud "bang" sound, which scared everyone. Seeing that the gas was almost filled, I stood up the wheel and shook it on the ground.

"No way! How could this happen? The wheel rim and tire are not sealed at all!" A young researcher couldn't help but express the thoughts of the onlookers.

“Why this phenomenon of seemingly not sealing but not leaking occurs, I’ll have to let you figure it out on your own.

These devices were pieced together by me using the Wood Release Technique, and they cannot be used for a long time. Next, you will need to redesign them and make tire equipment that can be used for a long time. "

Soon, the four new slime rubber tires were inflated and installed on the Xuanyuan Dragon crystal stone car at the door. On the other side of the door was the Xuanyuan Dragon with the old solid tires.

"Ningguang, let's try it together?"

"Well, let me see what the difference is between the tires you spent so much effort on and the previous ones."

Ningguang, sitting in the passenger seat, felt the new tires.

"It seems that the vibration amplitude is much less than that of solid tires."

"Its advantages are lighter weight, better elasticity and lower price. The solid tires of the past will be used on large vehicles or special vehicles in the future."

“There seems to be less noise.”

"There are many disadvantages to pneumatic tires, such as punctures, blowouts, and air leaks. In the future, there will be an industry for tire repair and vehicle maintenance.

Liyue is one step ahead, but overseas markets still need some time to develop. These tires will be a trillion-mora business in the future, so don’t underestimate these inconspicuous tires.”

After going around in a circle, Lin Zixuan and Ningguang got on the Xuanyuan Dragon with solid tires next to the door again.

After passing a short section of road with some potholes, Ningguang was so jolted that she wanted to get off the car.

"You deliberately?"

"No? That's the situation with solid tires!"

"Forget it, I'll deal with you tonight."

After Lin Zixuan and Ningguang left using the teleportation anchor, these researchers rushed to the Xuanyuan Dragon with inflatable tires, all wanting to try out the effect of this car.

In mid-June, an announcement from Xuanyuan Trading Company once again attracted the attention of the continent of Teyvat.

[Xuanyuan Company will recall all crystal vehicles that have been sold. The original solid tires will be replaced with new pneumatic tires free of charge. Some rubber pipes in the car will also be replaced with new slime rubber pipes.

You can also choose to purchase the new slime rubber solid tires as an additional option.

Due to the large number of crystal cars, please go to the crystal car store in advance to make an appointment.
