I ran to the Jinchuan Daily, and was delayed by reporters for so long. When Jin Feng returned home, it was almost noon.

Originally I planned to come back to drink saliva, rest my feet and go out, but after I came back, I saw Mancang with Wan Heming Zi Yuan Yuan and Liu Buqun.

"Didn't you sleep at dawn, why did you get up so early?" Jin Feng frowned.

"Teacher, you are back, of course we have to ask for An An!"

Wan Heming ran over with a dog's leg, saluting with a smile.

Jin Feng glanced at him, there was no good atmosphere: "What's the matter directly!"

Wan Heming is the youngest, but his heart is the most.

When I first came in the village, I was still a little genius, but I found that as long as I said that it was nice, after the villagers had a response to him, Wan Heming slowly became smooth.

In fact, such people can be more mixed. As long as the essence is not bad, Jin Feng is too lazy to care about him.

"The teacher is still wise as always!"

Wan Heming first filmed another horse, and then said: "Disciples and Mr. Liu, Mr. Liu, recently studied the steam machine on the car, but the effect has been unsatisfactory, I want to ask the teacher!"

When Jin Feng saw a few people just now, he guessed that they were for this matter, and nodded and said, "Come in, I just have something to ask you."

After entering the room, Jin Feng didn't say the steam engine, and turned his head to look at Mancang: "Did I make things you prepare?"

Before he came back, he listed a form that the production barrel needed to use, sent someone into several teams, and sent it back to let Mancang prepare in advance.

"If you return to Mr., you are ready for other things, but the machine tool is not very ideal, I am afraid that the precision does not meet the requirements of Mr.."

Answer a honest answer.

For Dakang, Jin Feng's concept of machine tools is too advanced, let alone full warehouse, that is, Wan Heming and Zuo Zhiyuan Liu Buqun. Jin Feng does not explain to them.

Then, then

The recent thoughts of Wan Heming's three people are on the steam locomotive. It is too difficult to improve the machine tool alone. It is too difficult to improve the machine tool.

Jin Feng was also mentally prepared for this result. He nodded and said, "I will be responsible for this matter."

"That's really great!" Mancang heard his words, he couldn't help but breathe.

His talents in machinery are far less than Wan He Ming, and there are many things in the steel factory. The focus of the work of Mancang today slowly transferred to administrative work.

Jin Fengneng was responsible for the machine tool, and he was much easier.

"As for a few of you, don't study the steam locomotive recently, go to the workshop to help me."

Jin Feng looked at Wan Heming again.

"What, don't study steam locomotive?" N

Wan Heming was anxious as soon as he heard it: "Teacher, you also saw the role of airship and speedboat. The application range of steam locomotives is wider than that of Airship speedboats. Once you study it, our strength can definitely go further!"

"The role of land locomotive is really large, but the steam machine is too large, and the requirements for the road surface are also high. It is not appropriate to put it on the car."

Jin Feng said: "Your thoughts are good, but the research direction is wrong. If you want to run the car on the land, the steam engine is not good, you have to internal combustion engine."

Wan Heming Zuo Zhiyuan, Liu Buqun, you look at me, I look at you, all of which have heard this term for the first time.

"Teacher, what is an internal combustion engine?" Wan Heming asked.

"The internal combustion engine is a power machine that is smaller in size, more sophisticated in structure, and has a more powerful output than a steam engine!"

Jin Feng took out the drawings of the internal combustion engine from the box and combined them with the drawings to explain the structure and principles of the internal combustion engine to the three of them.

Mancang also joined in.

It's a pity that his mechanical talent is not very good and he can't understand it at all.

But Wan Heming and the others' eyes became brighter and brighter as they listened, and finally their breathing became heavier.

"Teacher, can you give me a copy of the drawing?"

Wan Heming can't wait to build an internal combustion engine right now.

"It's useless to give it to you. Making an internal combustion engine requires various machine tools. Even if I give you the drawings, you won't be able to make it."

Jin Feng put the drawings away directly.

"Teacher, don't worry, we will upgrade the machine tools as soon as possible!"

Wan Heming patted his chest and said.

Zuo Zhiyuan and Liu Buqun also followed suit.

After learning about the internal combustion engine, the three of them didn't want to wait any longer. They said hello to Jin Feng and went back to study the machine tools.

Jin Feng looked at the backs of the three of them and sighed helplessly.

He just told the three people about the structure and principles of the internal combustion engine, but did not talk about the fuel problem of the internal combustion engine.

To drive the steam engine, you only need to boil the water in the boiler. There are no big requirements for the fuel for boiling water. Coal and firewood will do.

But to drive an internal combustion engine, oil must be used.

There are coal seams on the surface, but the domestic oil is basically thousands of meters underground. With Xihewan's current industrial capacity, even if Jin Feng knew where the oil fields were, there would be no way to extract them.

So he asked Wan Heming and others to modify the machine tools, with the ultimate goal of producing rifles. As for the production of internal combustion engines, it would probably take at least several years.

"If we can't produce the rifle for the time being, we have to tell Wuyang."

Thinking of this, Jin Feng packed up the drawings on the table and prepared to go find the Ninth Princess.

As a result, as soon as I came out of the house, I saw Pearl coming.

"Sir, Your Majesty invites you to come over for a meeting."

"What happened?" Jin Feng asked.

"I don't know," Pearl shook her head.

"Who is at the meeting?"

"Master Tie, Master Xiaoyu, and Li Didi." Pearl replied.

"I understand," Jin Feng nodded, roughly guessing the reason why the Ninth Princess held this meeting.

In the Ninth Princess's study, the Ninth Princess sat on the main seat, while Tie Shixin, Xiaoyu and Li Didi sat on the small stools below.

Seeing Jin Feng come in, everyone stood up and saluted.

"Wuyang, are you discussing going to Tubo?" Jin Feng asked.

"Yes," Ninth Princess asked, "I want Li Didi to lead a team to Tibet. What do you think, husband?"

Although Li Didi is not very old, during the Xizhou battlefield, Li Didi went to the Dangxiang Nanzheng Camp to negotiate with Li Lingrui alone, showing his strong psychological quality and ability to adapt to the situation, making him a good candidate to be an envoy.

Nowadays, all the tribes in Tubo are beaten down by the tribes with hot air balloons. They are asking for help from Sichuan. This trip is much simpler and safer than the last time. Jin Feng feels that with Li Didi's ability, there should be no problem.

big.

"I think it's okay," Jin Feng nodded and asked, "When will we set off?"

"If your husband has no objection, how about setting off tomorrow?" Ninth Princess replied.

"Tomorrow?" Jin Feng frowned and said, "Is it so urgent?"
