Li Chengqian's two younger brothers still didn't believe it.

There is no plant in the world that can solve this problem!

But Sun Simiao said three words unhurriedly.

"Eucommia gum!"

Li Ke said: "It's not called glue, you can use it!" ”

This is also what people think, and it must be useful if it is not a name.

"The old man once found out from a village that they had used this thing to make umbrellas, and the effect was quite good. Whether it works or not, try it and you'll know. The two princes, questioning the old man here, it's better to give it a try! ”

Sun Simiao ignored other people's doubts, and his personality suddenly became very rigid.

Li Ke and Li Tai stopped talking.

and set his sights on Li Chengqian.

At this time, Li Chengqian heard the three words of eucommia gum, so he quickly found a book from the system.

"Wait here for me! I'll go to my room first and check something. ”

Then I wanted to go into my room, exchange the book, and study it.

It made everyone present wonder.

What happened to the prince?

"Big Brother ......"

"Wait outside, this king will check something!"

This is the first time they have to check things behind closed doors.

Is there some secret in this room?

Although there were many questions, they did not dare to say anything more.

It wasn't until Li Chengqian discovered that there was such a record.

Eucommia ulmoides is a unique and valuable economic tree species in China, and it is also an important collagen plant with the most extensive application in the world. The leaves, bark and peel of Eucommia ulmoides are rich in a white filamentous substance, Eucommia ulmoides gum. Eucommia ulmoides gum has a unique "rubber-plastic duality". That is, it can replace rubber trees.

Eucommia ulmoides is a unique plant in China, and more than 95% of the world's eucommia resources are in China. Eucommia ulmoides is also a high-quality gum source tree species with the widest range of adaptation and the greatest development potential in the world.

Based on the unique structure and properties of Eucommia ulmoides gum, three types of materials with different purposes can be developed: rubber high elastic materials, low-temperature plasticity materials and thermoelastic materials, which are widely used in rubber industry, aerospace, national defense, shipbuilding, chemical industry, medical treatment, sports and other fields of the national economy, with a wide range of industrial coverage.

It couldn't be better for use as an airtight filler for a steam engine.

Look at the book again, there is actually about the refining method and production process of Eucommia ulmoides gum, which is the most advanced process.

If that's the case, then that's it.

Just do it, Li Chengqian pushed the door open.

Under the eyes of everyone, he took Sun Simiao's hand and said, "Sun Zhenren, you have done this king a great favor this time!" Eucommia gum really works! ”

Now the other people were stunned, why did he say such things as soon as he went in and came out?

What happened to him in it, and why was he so sure of the effects of eucommia gum?

Sun Simiao said with a smile, "Needless to say, it is an honor for the old man to be able to contribute to the teacher!" You saved my life, and there is nothing to repay such a great kindness, just to provide some information. ”

Li Chengqian was a little moved.

Sun Simiao really didn't save in vain!

"Good, good, good!"

Then he said to the two younger brothers: "You take out the gum of Eucommia according to the method in this book, and then apply it to the steam engine, be fast!" ”

The two took the book, a little puzzled.

When I saw the contents of the book, I made a shocked sound.

"This book...... What a timely rain! ”

Li Ke laughed.

Li Tai also glanced at the book and couldn't help nodding yes.

"Big brother, let's go down and study now!"

After that, the two of them hurriedly left the East Palace with Laiji.

Eucommia has a lot of wild ones in Datang, and with Sun Simiao's help, it is very fast to select these eucommia.

In only three days, Li Ke and the three of them successfully produced 100 catties of eucommia ulmoides glue, which was enough to complete the sealing requirements of the steam engine.

After boiling the gum of Eucommia, everyone and the craftsmen enthusiastically sealed the steam engine.

After the completion of the work, they sent someone to invite Li Chengqian over to watch the trial operation of the steam engine.

In this way, Li Chengqian came to the place where the Ministry of Science and Technology was located.

At this time, Li Ke and Li Tai were extremely happy, they didn't have the frowning and bitter faces they had before, and the three of them greeted Li Chengqian.

I saw a huge steam engine appear in front of Li Chengqian.

Laiji commanded below.

"Ignite the coal!"

The craftsmen shoveled the coal into the boiler and started the fire.

It didn't take long for the water to boil, and with the blessing of eucommia gum, there was no air leakage this time.

All eyes were on the flywheel on the steam engine, and the mark of success was whether the flywheel could spin or not.

Flutter flutter

With a loud roar, the steam maneuvered. The flywheel spun violently.

This huge steam engine, like a monster spewing smoke,

This is the heart of the train, without which nothing can be done.

With it, it can even be applied to ships, as well as to various industrial sectors.

With it, Datang can be pulled into the steam age!

That national strength has a huge increase, it can be said that when all countries in the world are crawling in open pants, Datang can already run.

"It worked! It worked! ”

"Great, finally succeeded!"

Everyone cheered and cheered each other.

Li Chengqian laughed.

"Finally it worked!"

"This king will find His Majesty to do your best! That's a big credit! Until then, the king will reward each of you with a thousand denarii! ”

More than 10,000 people, that would cost more than 10 million dollars, such a terrible expenditure, I'm afraid only Li Chengqian has the ability, why? Because his business bank is already the No. 1 existence in Datang, he can still get it for a mere 10 million dollars.

Everyone cheered, this was only Li Chengqian's reward, and Li Shimin would reward it once.

He added: "The steam engine still has some shortcomings, and it needs to be improved, and there are still many problems!" Trains were to be brought into the process, including steamships, and everything that could replace human horsepower, as long as the steam engine could do. ”

The crowd cheered, "Yes!" ”

As for Li Tai asked: "Big brother, do you want Your Majesty to know about this?" ”

Li Chengqian flatly refused.

"Nope! Don't let Your Majesty know for the time being, when the train comes out, this king will naturally bring His Majesty to experience, and you will behave well at that time! Well done, there is endless money and glory. ”。

It's just a steam engine, it doesn't mean much for Li Shimin to know, he must want results, how can he imagine what is inside, what has not been applied? All this has to be experienced by oneself in order to be profound.

Everyone dances, and there is nothing more shocking than this.
