The place where the oil was dug out was indeed not far from the original place, and it seemed to be an oil field.

Yan Ming told everyone to keep this place.

Elder Chen: They arrived later.

When Yan Ming saw Elder Chen, he grabbed him and said, "I'm afraid I'm going to have to work hard for you this time." ”

In oil refining, the easiest way to do it at the beginning was to distill the petroleum, distilling gasoline, diesel, kerosene, paraffin wax and oil residue according to their different melting and boiling points.

With the current technical means, it is very easy to build a small soil refinery.

Yan Ming and Da Lao Chen studied in their room for a few days before they thought of a set of plans and formed a drawing.

Seeing Yan Ming desperately making drawings, Da Lao Chen knew that this thing was very important.

After asking a few times, Yan Ming said briefly, and then said: "Just like the steam engine, if the connecting rod and friction of the steam engine can be coated with the lubricating oil we distilled, then the work efficiency of the steam engine will be improved a lot." Coupled with the water cooling system, it can work for a long time. ”

The two of them were working while Yan Ming explained.

Elder Chen gradually understood the importance of oil.

The north, which later became the heavy industry base of New China. Not without reason.

Now, Yan Ming is starting to take off in the north and has decided to rebuild this heavy industrial base. If you want this place to take shape, the most important thing is to have people.

And talents, need to be introduced.

It would be interesting if the Han people from the Central Plains could migrate here.

The drawings of the earthen oil refining equipment were explained by Yan Ming to the elder Chen.

Yan Ming decided to personally supervise the construction. Once successful, it will be a qualitative leap.

At this time, the third envoy of the Han Dynasty arrived.

After they arrived in Xincheng first, they were told by the people of Xincheng that they hurried all the way to find Yan Ming.

Seeing the messenger coming, Yan Ming's face moved slightly.

It was none other than Tian Wei.

"Yanhou, don't come unharmed." Tian Wei saw Yan Ming's dust, wearing coarse cloth clothes and working with everyone, and even came to say goodbye.

Yan Ming spread his hands outwards and said with a smile: "Do you look at me like this, do you seem to be fine?" After saying that, he laughed.

"Although Yan Hou is dirty, his spirit is good. Yesterday in Xincheng, I also met the two children in the family, yes, they are all good. "Tian Wei is still very good at talking. But now his relationship with Yan Ming will not lie and deceive.

"Wu Anhou came all the way to this poor country, there must be a big deal." Yan Ming rubbed the dirt on his hands, handed the shovel to the people around him, and walked over by himself, with his arms outstretched, as if he wanted to hug Tian Wei.

"Come less, come less, I won't hug you. It's dirty. Tian Wei was undisguised and unceremonious.

Yan Ming smiled: "You Lao Tian, it's not good at all, so you can't accommodate it." ”

Tian Wei shook his head and said, "What I envy the most is your temperament. Have you built a villa here? If there is, I'll buy a set too. I just think it's fun to be with you. ”

"It's as interesting as it is in Hongyan Hall, they are all my students." Yan Ming said with a smile.

"Pull it down, after you leave, Lao Dou will be sick, and you don't think lightly. Liu An, this guy, is full of benevolence and morality, but he is a cautious guy, Lao Dou was sick for two days, and he didn't pay Lao Dou a salary. Do you say that people are angry? Tian Wei said, and his hands trembled.

Yan Ming didn't expect that Tian Wei would transform like this, and he was upset for Dou Ying.

"King Huainan won't be like this, right?" Yan Ming said.

"He focused all his energy on making compulsory education universal. It's not very strict with Hongyantang. If it weren't for Lao Tzu and him, maybe Hongyantang would have been scattered by him. Tian Wei scolded his mother and said: "He just wants to be a saint and leave a name for eternity, and people are stupid." ”

"You Lao Tian, you are still so harsh. King Huainan thinks like this, which is not necessarily a bad thing. Yan Ming smiled.

Tian Wei sneered and said, "If it weren't for Lao Tzu's threat of wanting to rebel in the past, I'm afraid this guy wouldn't have stayed in Hongyan Hall honestly." Yan Ming, I think something will happen to Liu An sooner or later. This guy is more eager for quick success than you. ”

Yan Ming snorted and said, "Lao Tian, you speak more authentically, when am I in a hurry for quick success?" ”

Tian Wei spit out twice and said, "I'm not scolding you, it's just an inappropriate word." It's that both of you are in a hurry to make a fuss in the academy. You are anxious to make everyone in the world aware of the importance of learning, and you want everyone to be literate. But Liu An is different, he just wants everyone in the world to know that he can read and write because he is promoting universal compulsory education. Such a mentality, if you don't rebel, will be hated by the emperor. ”

Tian Wei's analysis is very correct.

Yan Ming was speechless.

The two chatted for a long time, and then Tian Wei smiled: "You see that my brain is confused. You prepare, get up tomorrow, and go back to Chang'an with me. The Empress Dowager was seriously ill, and the imperial doctor said that her life would not be long in coming. In addition to the emperor every day, the old lady chatters the most is you. ”

"Ahh Yan Ming was a little surprised.

Empress Dowager Dou has always been, although her eyes are not too good, but her body has always been tough, why is she going to leave now?

After asking what he thought, Tian Wei smiled.

"I said Yanhou, how long have you been away from Chang'an? Five or six years. It's nothing to you as a young man, but for the Empress Dowager Dou, five or six years may be a process from birth to death. Tian Wei said.

"Okay, we've done a good job of teaching and educating people." Yan Ming said complimentarily.

Tian Wei waved his hand and said, "Don't praise me. When you praise me, I think a lot, wondering if you are scolding me in a different way. It's tiring to talk like that. ”

Yan Ming laughed and said, "Lao Tian, Lao Tian." You said that the two of us didn't like each other at the beginning, but now that we are old friends, I want to scold you for still changing your ways? ”

"That's just as well." Tian Wei said: "Do you want to go back to Chang'an with me?" ”

Yan Ming looked at the south and said, "I may not care about other people's affairs. But the Empress Dowager Dou is seriously ill, and Yan Ming will definitely return to Chang'an and give her a ride to the old man's house. ”

"I knew you were a man of love and righteousness. The last time Wei Qing came, the main messenger chosen by the emperor was me. But I don't think there was any reason to come back. Now that the Empress Dowager is seriously ill, I have calculated that you will go back. So, I deliberately looked for this errand. First, I really hope you go back as soon as possible. Second, it's Lao Tian Zhente who misses you. ”

Tian Wei doesn't have many times to reveal his true feelings, and there is absolutely no false ingredient in it this time.
