Wang Shengnan sent someone to find the rubber tree and had to use a lot of manpower and material resources, so naturally he would inevitably use the people at home.

Therefore, the two trucks of rubber blocks I brought back were left by my family. Although they didn't know what the rubber block was, since this is what Su Cheng Xinniannian wanted, it means that the rubber block must have great value.

If they had not fully believed in Su Cheng's ability, they would not have agreed to Wang Shengnan to mobilize so much manpower and material resources to find the rubber tree.

They firmly believe that since Su Cheng is always going to get rubber, then rubber must be a priceless treasure!

So, they even thought about leaving both trucks of rubber blocks behind.

But there is a problem in front of them. They don’t know what the rubber block is for, because the rubber block does not look beautiful and is not a treasure worth appreciating and playing with.

If you want to know what rubber blocks are, there is only one way, that is, give Su Cheng a truckload of rubber blocks and then see what these rubber blocks are used for.

Su Cheng was very surprised. He didn't expect that Wang Shengnan not only found the rubber tree, but also brought back a truck of rubber blocks.

"I actually brought back a truck of rubber blocks? And it's in Chang'an? It's great!" Su Cheng said in surprise.

Wang Shengnan was still a little embarrassed after saying that, after all, the person she sent brought back two trucks of rubber blocks, but the family left one truck.

"My family had to leave a car, and wanted to see what rubber is useful, so I only brought one car."

However, Su Cheng didn't care at all that Wang in Taiyuan left a car. In fact, rubber is not a rare thing.

Not to mention that people from the Wang family in Taiyuan don’t know how to use rubber, they hope that industry can develop in the Tang Dynasty.

Su Cheng smiled and said, "It's okay. They stay as long as they want. Rubber has many uses. For example, it can be made into tires, but it cannot be made into inflatable now. It should be good to make it into solid ones. It will definitely be more comfortable and durable than wooden wheels."

Wang Shengnan was confused when he heard this. Didn’t he say that rubber can be made into a car that can be moved by itself? How can it be made into wheels? It’s more comfortable and durable? Does it mean that it will be moved by itself when it is made into wheels?

"The key is that I don't know if the rubber I found is actually it!" Wang Shengnan said nervously.

"Is it rubber? Just go and see?" Su Cheng smiled.

"Now?" Wang Shengnan asked in surprise.

"If nothing happens, then now." Su Cheng smiled.

Wang Shengnan was both happy and a little disappointed when he heard this. It was because she wanted to get along with Su Cheng more, and it was because the gift she prepared really made Su Cheng very happy and caring.

Wang Shengnan tidied up his dress, and then walked downstairs side by side with Su Cheng, attracting a lot of attention along the way.

Many people in the library recognize Wang Shengnan. After all, Wang Shengnan often comes to the library and is also one of the main organizers of the library. He is on the list of contributions in front of the library.

One is Duke Rong of the Tang Dynasty, Princess Changle's son-in-law, and the other is the eldest lady of the Wang family in Taiyuan, walking side by side in the library.

It must be because of the library! It must be like this, after all, both of them made contributions to the construction of the library.

Originally, Su Cheng planned to go to the firearms prison, but now he has already put the matter of going to the firearms prison behind his mind, thinking it is rubber.

In fact, Su Cheng had thought about making a steam engine. After all, the principle of the steam engine is relatively simple. Su Cheng also knew this, but what made him worried was what pistons use to achieve the sealing effect.

If there is rubber, this problem will be solved.

Isn't it just to make rubber seals? Su Cheng is still very confident about this. Su Cheng is easy to find sulfur. If carbon black is used, vegetable oil can be collected. If pine branches burn black smoke, use it as a makeshift. If stearic acid, try using vegetable oil or wax. If zinc oxide, zinc ore must be found to prepare zinc carbonate.

As for accelerators, don’t think about it. It’s just that the vulcanization speed is slow, it doesn’t matter.

It’s either that there are high requirements or that it is a simple sealing ring. Su Cheng thinks that just relying on these superficial means is enough.

Su Cheng rode his horse next to Wang Shengnan's carriage and kept thinking about it in a daze, but he was eager to try it out in his heart.

Steam engine, that was the steam engine that triggered the first industrial revolution.

Not to mention anything else, just using it on trains and ships will have a huge impact on this era.

It’s exciting to use a steam engine to build a car.

In previous lives, cars were already very common and nothing was rare.

But now, Su Cheng misses the cars of later generations very much. Although he cannot make internal combustion engines yet, it is also satisfying to make a car with steam.

And he is not just playing around, because although steam cars are unreliable and cannot be promoted, steam trains can be promoted.

Along the way, Wang Shengnan lifted the curtains from time to time and looked out, to be precise, he was looking at Su Cheng, but Su Cheng never turned to look at her.

Along the way, Su Cheng frowned from time to time and smirked from time to time, which made Wang Shengnan laugh but couldn't help but look at him.

It is said that serious men are the best. Su Cheng thinks so seriously, she feels very charming.

It was almost here, but Su Cheng seemed to have forgotten that she was by his side. Wang Shengnan pouted slightly and asked, "What are you thinking?"

When Su Cheng heard the voice, he turned to look at her and smiled, "I'm thinking about how to make a car that I can walk on my own!"

"Have you figured it out?" Wang Shengnan asked curiously.

Su Cheng nodded and smiled, "I understand it in general, but I still need to try it, and it should be done soon!"

If a person does not know the principles of a steam engine, it may take several years or even decades to invent and improve the steam engine. If a person already knows the principles of a steam engine and knows a mature plan, it only takes half an hour to figure out how to make a steam engine.

Seeing Su Cheng's confident look, Wang Shengnan was full of expectations. What would it look like if a car could walk by himself?

It must be very beautiful, must be surrounded by fairy spirit, and maybe it will emit golden light. Wang Shengnan tried hard to imagine in his heart.

"At this time, the rubber blocks are in the warehouse inside the manor."

The carriage drove into the manor, and Su Cheng also entered the manor with him. Wang Shengnan looked up at Su Cheng, and his heart suddenly became very nervous.

She prayed secretly in her heart, but don’t make any mistakes!
