A group of princes battled the air here, but Gao Li didn't have time to think about these questions.

Coal in this world is produced only sporadically, and there are very few people who use coal in the Central Plains. This means that it will be a huge blue ocean market. Gao Li didn't know much about the equipment needed for coal mining, but according to what his uncle, who worked in the coal mine, used to talk about, what shafts, ventilation, drainage, support, coal mining, transportation, coal washing, and coking.

A series of follow-up is a thing.

Wouldn't it be wonderful if the coal fields here could really reach the level of open-pit mining, and there would be no need to worry about toxic gases when large construction machinery entered. Build a coal washing plant and another coking plant nearby.

The principle of a jigging machine is not complicated, it is enough to complete the separation technology of coal gangue and coal, there are enough water sources here, the selected refined coal and coal slime can be used as fuel, and the coal gangue can be backfilled underground, which is a trivial matter.

Coking plant ......

Coal coking is a process that is easier said than done. Coal undergoes various changes at high temperatures, splitting gas and tar into so on. There is no need to ask about gas, in the early years, every household burned gas. Theoretically, this thing can be used as a high-end fuel, but there is no good way for Gao Li to use tar. First of all, tar is difficult to collect, and when it is collected, he does not know how to do it. At present, Gao Li only knows that coal tar can be used to make asphalt, which is also the main way to obtain aromatic hydrocarbons. But when it comes to chemical industry, this is not Gaoli's strong point at all. Unless at this time, Zu Long will summon a high-level chemical student...... No, not for high-quality chemical students. It has to be someone who can build the equipment, at the level of a technician in a chemical plant.

But for now, there seems to be little hope. The problem now is that Gao Li doesn't even have a good grasp of the structure of a modern coke oven.

Well, at least do a low-temperature dry distillation first to get the coke out.

On the road, Nonoka drove, Gao Li wrote and drew in a notebook on the co-pilot, Ruan Weiwu occasionally glanced at it, and he couldn't understand what those weird machines were for. On the contrary, Du Miaona is called an obsession. Du Miao had always liked these metal mechanical things, after all, when he didn't know Gao Li, he made a lot of it himself, and even sold a machine to Gao Li - although Gao Li only valued the combination of biological machinery.

At this time, he saw Gao Li drawing here, so he simply lay on the back of Gao Li's chair and looked seriously.

"Can you read this? Gao Li pointed to the three views above and some data and asked, this is the foundation of mechanical drawing, if you can understand this, it means that this person has a good foundation.

"Yes, isn't that talking about how big this machine is?" said Du Miao.

"Well, that's what it means, here?" asked Gao Li.

"This indicates how this part is assembled, and the numbers above are the assembly order. Du Miao said.

Gao Li listened and said with a smile: "Prince Du Miao is really powerful, if you are not a prince, I really want to partner with you to open a factory." ”

When Du Miao heard this, his heart moved, and he said, "Yes!"

Gao Li said: "As your prince, is it okay?"

Du Miao laughed and said: "You can be the king of Yannan, what is wrong with me as a prince? I'm not afraid of your jokes, in fact, my favorite is this, don't look at me as a prince, in fact, my favorite is these metal machines." If you're really interested in pulling me in, I promise I won't hold you back!"

When Gao Li heard this, he smiled and said, "In this way, it is okay, in the future, I plan to start from here and build several factories, and I need your help for future operation and expansion." ”

When Du Miao heard Gao Li say this, he slapped his hands excitedly and said: "Don't worry, Lord Gao, I Du Miao can't do anything else, as long as it is something related to machinery, I promise that I will never let you down!"

As he spoke, Du Miao glanced back at Ruan Weiwu, who was there with his eyes closed. And Ruan Weiwu gave him a smile, but thought in his heart: "I want to strangle him!"

Why is this dead monkey so lucky? Obviously, I came first! Whether it is business or land, it is all mine first! How can he attract Gao Li's attention with just one stone?

Du Miao is really proud, and Ruan Weiwu is really angry!

Twice! Exactly twice!

For the first time, we negotiated with Gao Li desperately in Yannan, signed an agreement, and accompanied the smiling face, and that dead monkey was sold for a sky-high price just by speculating!

This time, it's still like this. This dead monkey is obviously just here to fight the autumn wind, and he is not so loyal to Gao Li at all. But in the end, just because of this black and unslick coal, he actually made a huge bargain from Gaoli!

Although Ruan Weiwu didn't know how important this coal-coal kiln was in Gao Li's plan, it could be heard from their words that Gao Li was planning to focus on developing this place!

Ruan Weiwu felt very aggrieved, the world is too unfair to him, why does this world always bully honest people? Why can't I, a hard-working person, get rewarded?

Ruan Suya, as Ruan Weiwu's daughter, understands too much what Ruan Weiwu is thinking at this time, but unfortunately, even she can't help it. After all, this kind of thing is all about luck, and Du Miao's luck is simply too good. I heard that Du Miao is addicted to gambling and likes to gamble money, but he can lose nine out of ten gambles and even lose every time he gambles. Could it be that this time, he actually got his luck back?

The rest of the journey went smoothly and no one came to trouble along the way. It seems that a devastating victory is enough to make those people understand a truth, that is, in this world, some people are not easy to mess with.

Coming to the Imperial City again, there is almost no change from the last time, when passing through the city gate, the last time Gao Li came to see it, this time it is still the same. Gao Li once saw half of the stone slab inserted in the gap and was about to fall, but today it seems that the half is still there. In other words, for such a long time, there are people coming and going at this city gate, and there is no one to help straighten it out, which usually means one thing.

The people of this city have no vitality.

Of course, this doesn't even need to be judged carefully to draw conclusions, after all, these people look blank and have no hope for the future.

Gao Li didn't come to be a savior, looking at their appearance, Gao Li didn't have much emotion except for shaking his head. However, the moment the car entered the city, he suddenly felt his ears buzz. Then, it was filled with a sudden cacophony of sounds. The voice seemed to come from the ears and from the depths of the head, and it sounded as if a dozen people were chattering non-stop. And the speed of speech is very fast, and the tone of the voice is very sharp. For a moment, Gao Li thought it was his tinnitus. But as he listened carefully, he could still understand some of the content. The content was not composed of any language that Gao Li understood, but it was as if it had been automatically translated. Those voices are supposed to be arguing over something, and the quarrel seems to be divided into several sides. But they are evenly matched, and no one can convince anyone.

At first, Gao Li only vaguely understood some words. But the longer he worked, the more words he could understand, and more and more.

Then, he found out that the quarrels of these voices were actually directed at him.

Some voices believe that Gao Li is an enemy and must not communicate with him;

Some voices believe that Gao Li is a friend, the key to their escape from the sea of suffering;

There are also voices who believe that it doesn't matter if these things matter, the key is to kill all the people in the Central Plains;

There are also voices that think that you are too noisy and delay my rest;

There are also voices that say, you are all idiots.

Although these voices were extremely chaotic, Gao Li still listened to them with relish. At this time, Gao Li was sitting behind the Zhenqi car, with Du Miao driving in front and Ruan Weiwu sitting in the co-pilot. Du Miao is full of interest in all mechanical things, and Zhenqi car is no exception. This real gas car does not need an accelerator pedal, as long as the real gas is injected into the steering wheel, so even Du Miao can still control it. And he really has a staggering talent, don't look at the first time he touched the real qi car. But after a few simple trials, he can now control it freely.

Because of this, Gao Li had the opportunity to listen to their quarrels with Xianqing here.

It was also in these voices that Gao Li suddenly heard such a set of conversations: "Erruo, since you like these monkeys so much, why do you just take the initiative to become those monkeys, why bother with us?"

Then he heard the voice of Elror: "Do you want to become a monkey if I like monkeys?

Gao Li laughed when he heard this, and couldn't help but say: "It's beautiful!"

"Who?"

"Who invaded our sea of consciousness!"

"It's Gao Li! It's Gao Li! He can hear our voices and invade our sea of consciousness, so I say that this person can't stay! He must be killed!

Then, the noisy voice suddenly quieted down, and no matter how carefully Gao Li listened, the sound would not appear. Then, in front of Gao Li's eyes, Erruo, who was still in a daze, suddenly opened her eyes, a purple light flashed from the bottom of her eyes, she looked at Gao Li, and then smiled: "Lord Gao is so powerful, even our sister's sea of consciousness can invade." ”

Gao Li said: "How can I have that ability, I thought it was similar to the voice that the residents of Yannan City could hear before." ”

Al Ruo said, "Didn't you listen to it yourself?"

Gao Li said: "Definitely not. ”

"I don't feel like it, but that's strange, how did you hear it?" ”

At this moment, the huge crack above the palace emitted a brilliant purple light, and the whole city was amazed by the change in this rift, and then Gao Li and El Ruo heard a deep voice at the same time: "Because, I want him to hear what these daughters of mine are doing. ”

That voice couldn't distinguish between men and women, between old and young, and it wasn't even a voice, but a simple message. Just like the way Zu Long communicated with Gao Li before, it was also like the way the daughters had just quarreled, this information was translated by Gao Li's brain and automatically transformed into something he could understand.

"What's going on?" Ling Long sensed that something was wrong and immediately held Gao Li's hand.

"It's okay, I just heard the sound of their sisters arguing. "Gao Li Dao.

"Oh, I heard it too, but unfortunately it was too small for me to understand. Ling Long said.

Gao Li nodded, then looked out of the car window, and said to the purple light that came over: "You are the mother of this world, all evil things?"

"No, I'm not all evil mothers, there are some of my compatriots in the Arctic who use ice to slow down annihilation, I think, you should have seen them. The Evil Mother said.

Gao Li said: "What should I call you?"

The Evil Mother paused for a moment, then said, "You can call me 'Ao'.

Hao, this name is very special, 10,000,000 for Yuan, using this as a name, you have to be quite confident in yourself.

"What you just heard was the quarrel between my daughters, how much did you understand?" asked him.

Gao Li said: "From the beginning of the part where they started to discuss whether to kill me, I could understand. ”

He said, "How do you feel after hearing them?"

Gao Li thought for a while and said, "I don't have too many feelings, after all, I don't expect everyone to like me." However, I certainly can't allow others to beat my mind casually. ”

"Elruo should have told you my request, right?" ”

Gao Li said: "Yes. ”

"If you can, I'd like you to kill two of them for me." They are my third daughter, Elyao, and my seventh daughter, Elba. ”

Oh, so the child's father's surname is Elbei.

Gao Li said with a smile: "I was entrusted with such a great responsibility when I first came here, I suddenly felt that the burden on my shoulders was so heavy, from childhood to adulthood, I didn't even dare to hurt a mosquito, I actually had to risk my life to help you solve the troubles in front of you, I really felt, so scared!"

"I can understand your concerns, and of course, I don't intend for you to help in vain," he said. I will help you with the invasion of the Eagle Demon, and I will help you even more with the invasion of the Celestials. In the past, the evil invasion of the Central Plains was essentially the work of my two daughters. I can assure you that in the future, as long as they die, we evil spirits will never enter the Central Plains. ”

"A promise from the evil mother, I'm curious to know, what can I do with you if you don't keep the promise?" Gao Li said.

"I understand your caution, I understand your concerns, and that's why I've found someone who can prove me. He said.

"Who is it?"

"You'll know when you enter the palace. ”

Also mysterious, this is playing a puzzle adventure game?

The convoy stopped outside the palace, and seeing that it was Gao Li and them, the royal guards who had already lined up immediately set up a formation to welcome Gao Li's arrival. It's a pity that the number of people is small, and the environment is very poor. Belong to the kind of people who know at a glance that this royal family is quite poor.

However, a person who ran out from the back of the team was much beyond Gao Li's expectations. Because that person turned out to be Chu Miaoyin, who I hadn't seen for a long time!
