Daming: I, Yang Xian, really govern Yang!

Chapter 207 Collision leads to success
Shen Cheng's words really surprised Zhu Bai.

Zhu Bai did not expect that the other party also knew about steam engines, and according to Shen Cheng's words, he was actually doing the same research as him.

Unlike him, Shen Cheng still received direct support from the person he respected most, Yang Xian.

The servant guarding the gate of Duke Yang's Mansion obviously knew Shen Cheng.

"Xiao Cheng, are you here to see Mr. Yang again?" Concierge Uncle Liu asked when he saw the kind smile on Shen Cheng's face.

"Uncle Liu, is Mr. Yang at home?" Shen Cheng asked.

The porter, Uncle Liu, smiled and said, "My lord is still at the house at this hour."

"Thank you, Uncle Liu."

After saying that, Shen Cheng took Zhu Bai together, bowed to the concierge, and went directly into the house.

Yang Xian specifically told him that if Shen Cheng came to the house to look for him, there would be no need to notify him and he could just come in directly.

These days, everyone in the Duke's mansion has become familiar with Shen Cheng and regards him as Yang Xian's student, although Yang Xian has never mentioned this.

In addition, Shen Cheng was polite and sensible, which made him very popular among people in the Yang family such as Uncle Liu.

Two people of the same age started talking about steam engines while walking.

Whether it is Zhu Bai or Shen Cheng, after these days of research, their understanding of steam engines can be regarded as the top three existences in the world.

They exchange experiences and insights with each other, learn from each other and learn from each other's strengths.

Then he walked all the way to Yang Xian.

Looking at the two people walking hand in hand, Yang Xian was stunned for a moment. Why did they come together?

Yang Xian was about to speak.

Zhu Bai took the lead and saluted, "Student Hong Bai, I have met Mr. Yang."

Hong Bai?

Yang Xian looked at Zhu Bai, and then glanced at Shen Cheng beside him, clearly seeing the young man's thoughts.

Shen Cheng also saluted and said, "Student Shen Cheng, I have met Mr. Yang."

Yang Xian did not open his mouth to denounce it, but said with a smile: "Okay, no need to be polite, you are all here for the steam engine."

The two teenagers nodded repeatedly.

"Let's talk about our progress." Yang Xian found a stool, sat down, and said.

Zhu Bai and Shen Cheng first reported on their research results these days.

Then he also explained the improved version that they had obtained after the two people had just exchanged their experiences.

After listening to the descriptions of the two men, Yang Xian was basically certain that the improved steam engine design they finally came up with was the first generation steam engine of the original time and space.

Yang Xian nodded, then shook his head.

"What you improve is the details, but as long as the most fundamental problem is not solved, then what you make is just a toy that uses the principle of a steam engine."

“Now do you want to understand why the steam engine you made doesn’t achieve the desired effect?”

This was a test question that Yang Xian asked the two people in front of him.

Shen Cheng pondered for a moment and then said: "The sealing is not good enough. Most of the air in the steam engine we made has escaped, and we cannot keep all the air in the steam engine."

A smile appeared on Yang Xian's face. Being able to think of this proved that Shen Cheng had really studied steam engines thoroughly.

"I have noticed this problem before, but I have tried many materials and can't solve it." Shen Cheng said.

"This thing can help you solve the airtightness problem of the steam engine." Yang Xian stood up, took out an iron bucket from behind, and placed it in front of the two teenagers.Shen Cheng and Zhu Bai quickly gathered around, looking at the iron bucket with curious expressions on their faces. After getting Yang Xian's permission, they couldn't wait to open the lid.

Inside the iron barrel is a white liquid, which is filled to the brim.

Shen Cheng stepped forward and smelled it, and a pungent smell hit his face.

Zhu Bai quickly covered his nose and said, "Shen Cheng, please close the lid quickly."

Shen Cheng stared at the barrel of rubber at close range for a long time, and then slowly closed the lid of the iron barrel.

"Mr. Yang, what on earth is this?" Zhu Bai asked.

Yang Xian chuckled and said: "This thing is called rubber, and it is cut from a plant called a rubber tree."

"Rubber, rubber tree?"

Shen Cheng and Zhu Bai looked at each other and both said they had never heard of it.

Even though they are young, it can be seen that they are very knowledgeable.

Shen Cheng has been with Shen Wansan since he was a child. He has seen all kinds of rare treasures from all over the world, and has also heard Shen Wansan talk about various experiences he encountered when he was young.

Needless to say, Zhu Bai's main hall was the place with the largest collection of books in the entire Ming Dynasty. He liked to read when he was peeing.

Seeing the two people confused, Yang Xian smiled and said: "It's normal that you haven't heard of it, because the rubber trees come from overseas. But a few days ago, I had people bring the seeds to Qiongzhou for planting. When the rubber trees grow, , use a knife to cut its outer skin and bast, and the latex that flows out is the rubber you see in front of you."

"Why did Mr. Yang travel thousands of miles to bring tree seeds to Qiongzhou for planting instead of planting them locally in Yangzhou?" Zhu Bai asked.

Yang Xian smiled and said: "Because of the rubber tree, it can only grow in tropical environments."

"tropical?"

"This involves another topic. When I have time, I will give you a geography lesson. You will know then."

Yang Xian looked at Shen Cheng and the others, and then asked: "Now back to the steam engine, apart from the air tightness, tell me what other reasons are there for the steam engine they made to be so weak."

Zhu Bai said: "It's fuel."

"I discovered this by accident. I ran out of firewood at that time, so I asked people to bring charcoal directly. Later I found that burning with charcoal can produce more power than burning with firewood directly."

Of course Zhu Bai knew why, but he didn't know why.

He didn't know that for a steam engine, anything that can burn can do work, but different fuel temperatures are different, and the energy released is naturally different.

"Charcoal." Yang Xian suddenly said.

"Mr. Yang is saying that the best fuel for steam engines is coal?" Zhu Bai asked.

"That's right." Yang Xian nodded and said.

The two biggest problems in making a steam engine were solved in this discussion between two teenagers.

There is such a saying in the world of martial arts.

The most taboo thing in practicing boxing is to have no master or opponent. If you have a master, you know how to measure, and you have an opponent who knows your level. A confidant is hard to find, and the same is true for your opponent.

The same applies to scientific research.

Yang Xian looked at the two teenagers in front of him, wanting to see how far they could grow to in the end.

Before they left, Yang Xian told them about the use of rubber and how to use rubber to make rubber gaskets for sealing.

Yang Xian believes that it won't be long before the world's first steam engine will be available.
