For dozens of days, Li Chengqian's resurrection of Sun Simiao spread throughout the Tang Dynasty, and people passed Li Chengqian's miraculous skills.

Some people even treat Li Chengqian as a god, and even set up a statue of God, and the entire Tang Dynasty is full of Li Chengqian's statues. At the same time, he was also worshiped by people's perfumes, but he was afraid that he was not a god, otherwise this incense was prosperous, and it would definitely bring a lot of bonuses.

Li Shimin also sent people to stop it, but he couldn't stop it.

It's not good to take Li Chengqian, because that was not what Li Chengqian asked him to do, but everyone organized it spontaneously.

Until the end, it was left to its own devices.

From this point, Li Chengqian said that he was very happy, which was comparable to the existence of great men.

But he still has to behave in front of Li Shimin, which is not the feeling I want.

Fortunately, Empress Changsun kept blowing the wind next to Li Shimin, saying that the prince's is the emperor's, and the prince's is also because of the emperor, otherwise the emperor will have to think more.

Of course, Li Chengqian also hid his clumsiness at the appropriate time and did not make too much noise.

Sun Simiao has also been visiting his door for a period of time recently, and it was Li Chengqian who gave him a second life.

On this day, Sun Simiao was discussing everything about life and medical care with Li Chengqian in the East Palace.

Suddenly, Li Ke and Li Tai came in with Laiji to look for Li Chengqian.

"I've seen big brother!"

"See His Royal Highness the Crown Prince!"

The three of them saluted separately.

Sun Simiao also nodded to the three of them.

Li Chengqian looked at the three of them and asked, "What's wrong?" Come to the East Palace today? Can I help you? ”

You must know that at this time, Li Chengqian kept the three of them very busy, in order to make the steam engine build earlier. They should be in the Ministry of Science and Technology, why did they come to the East Palace again?

"Big brother, let's talk about this matter!"

Li Ke said.

Lai Ji came out of the column and opened his mouth and said: "His Royal Highness the Prince, there are two news, one good and one bad. ”

"Let's talk about it first."

"We've built a steam engine."

As soon as his words came out, the expressions of Li Ke and Li Tai were excited.

Also proud.

At the same time, Li Chengqian was very shocked, it had only been a long time for them to make it.

Then there's the train problem.

As soon as this heart part comes out, the next step is to improve, whether it is from the material or some structures, it must be continuously improved, so that it can have greater explosive power and durability.

It can be said that when the steam engine appears, Datang's tentacles will touch every corner of the world.

Li Tai also said:

"Yes! Big brother, it's all going to be a lot faster than we thought, we thought it might take three months to make it! ”

After he and Li Ke participated in the affairs of the Ministry of Science and Technology, they felt like they had grown up overnight, and they were much more mature in handling things.

They were also called the second Li Chengqian by the ministers, and some people said good things in Li Shimin's ear, saying that they were similar to Li Shimin.

Li Ke said: "This is what we expected, but the quick results are not necessarily good, some problems appear directly, and these problems will be let Laiji Daoming." ”

"Just bad news?"

Lai Ji said: "Yes, His Royal Highness the Prince, the speed is too fast, and problems will follow." Other problems can be solved, but there is one problem that we still can't solve. ”

"What's the problem?"

"We have learned a lot of knowledge about air tightness, but we can't find an existence in Datang that can make air tightness better. We've tried a thousand things, but we can't get into the rubber that the book says. Because of the problem of air tightness, the steam engine cannot be driven well, and the energy loss is very large. ”

Natural rubber is produced from the rubber tree, a plant of the Euphorbiaceae family, native to the Amazon forests. Rubber trees are native to the western region of the Marayaan region of the Brazilian Amazon basin and are mainly found in Brazil, followed by Peru, Colombia, Ecuador, Guyana, Venezuela and Bolivia.

At this time, Datang couldn't touch the rubber at all.

Without rubber, the steam engine made is completely unusable, and if you can't find a replacement, it's a waste of work.

No wonder these three people came to find themselves, they must have thought they had a way.

Li Chengqian has a way, but this method is exchanged in the system.

But he wouldn't do it, because the demand was thousands, and he would waste so many points for a steam engine?

It's not what he wants to do, what he wants to do is sustainability.

Sun Simiao, who had been silent, asked at this time: "What is rubber?" ”

This question is really hard to describe, especially for Sun Simiao, who doesn't know how to do it.

Li Chengqian said:

"How so? Rubber is an elastic substance, with very strong ductility, and not easy to break, it is a colloidal object. It can be used as a seal, and if some jars containing food have rubber seals, the food inside can be stored for a longer time. ”

In this way, it is very clear.

Sun Simiao nodded, thought for a moment, and then said:

"Oh? It turns out that this is the case, the old man knows that there is a plant, which is a traditional Chinese medicine, maybe it can be used! ”

As soon as Sun Simiao's words came out, everyone was puzzled, how could you, a medical student, solve a problem that even scientific researchers can't solve!

Li Ke first said: "Sun Zhenren, this king is not questioning you, but this medicine and science are two different things, how can Chinese medicine solve the problem of air tightness?" ”

This is people's first reaction, in their opinion, Chinese medicine is Chinese medicine, how can it be used as a material? And they can't try so many things, how can he have a Chinese medicine?

Li Tai also came out and said: "Yes, this is not simple, although we know that Sun Zhenren is dedicated to Datang, but this is not a joke!" ”

Neither of them thought that Sun Simiao could solve the problem of air tightness, but Li Chengqian had different ideas, Sun Simiao, as the king of medicine, naturally understood the characteristics of some drugs, just like rubber, it was also extracted from rubber trees.

If so, maybe it's really possible.

Sun Simiao just smiled, and didn't fight with the two of them, because there was nothing to fight about, and he didn't know whether that thing would work or not, and everything would have to wait until after the test.

After being reborn, Sun Simiao knows more about forbearance, not rushing or grabbing, the way of nature.

"Don't talk about it, let Sun Zhenren tell me what kind of plant it is, this king wants to know!"

So, he stepped in to stop his two younger brothers.

The two didn't say anything more.

Sun Simiao nodded towards Li Chengqian and said three words.

As soon as these three words came out, everyone was surprised, did it really work?
