A group of princes are fighting wits and courage with the air here, but Gao Li has no time to think about these issues.

There are only sporadic coal in this world, and few people use coal in the Central Plains. This means it will be a huge blue ocean market. Gao Li doesn’t know much about coal mining, but according to what his uncle who works in the coal mine once often talks about, such as vertical shafts, ventilation, drainage, support, mining, transportation, washing coal, and coking.

A series of follow-ups are all things.

To be honest, if the coal fields here can really reach the level of open-pit mining, wouldn’t it be too wonderful? If large-scale engineering machinery enters the site, there is no need to worry about toxic gases. Build a coal washing plant nearby and a coking plant.

Gao Li, a coal washing plant, can still deal with it. The principle of a jigging machine is not complicated and is enough to complete the separation technology of coal gangue and coal. There are enough water sources here. The selected refined coal and coal sludge can be used as fuel, and coal gangue can be backfilled underground. This is a trivial matter.

Coking plant...

Coal coking is a simple and complicated process. Coal will undergo various changes under high temperatures, splitting out gas and tar, etc. No need to ask about gas. In the early years, every household burned gas. In theory, this thing can be used as high-end fuel, but Gao Li has no good idea to use tar. First of all, tar is difficult to collect, and he doesn't know how to do it. At present, Gao Li only knows that coal tar can be used to make asphalt and is also the main way to obtain aromatic hydrocarbons. But once chemical engineering is involved, this is not Gao Li's strength at all. Unless Zulong summons a high-tech chemical student at this time... No, chemical student can't do it. This must be the person who can build related equipment, and the technician level of a chemical factory.

However, at present, hope is slim. The problem now is that Gao Li doesn't even have the structure of a modern coke oven.

OK, at least do a low-temperature distillation first and get the coke out.

On the way, Nonoka drove, Gao Li used a notebook to write and draw in the co-pilot. Ruan Weiwu occasionally glanced at it, but he couldn't understand what the weird machinery was used for. On the contrary, Du Miao was so obsessed. Du Miao had originally liked these metal machinery things. After all, when he didn't know Gao Li, he made a lot of tricks on himself, and even sold a machine to Gao Li. Although Gao Li valued only the combination of biomechanical technology.

At this time, he saw Gao Li drawing pictures here, so he simply lay behind Gao Li's chair and looked carefully.

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

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

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

"This means how this part is assembled. The numbers above are the assembly order." Du Miao said.

Gao Li heard this and smiled and said, "Prince Du Miao is so amazing. If you are not a prince, I really want to open a factory with you."

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

Gao Li said: "With your prince's identity, is that okay?"

Du Miao laughed and said, "As the King of Yannan, you can do it. What's wrong with me? I'm not afraid of you making jokes. Actually, this one is my favorite. Don't think I'm a prince, in fact, my favorite is these metal machinery. If you are really interested in pulling me into the group, I promise not to drag you down!"

When Gao Li heard this, he smiled and said, "That's good. In the future, I plan to start from here and build several factories. I need your help in the future operation and expansion."

When Du Miao heard Gao Li say this, he immediately slapped excitedly and said, "Don't worry, Prince Gao, I, Du Miao, are not good. As long as it is related to machinery, I promise that I will never disappoint you!"

As he said that, Du Miao looked back at Ruan Weiwu who was resting with his eyes closed. Ruan Weiwu gave him a smile, but thought to himself: "I want to strangle him to death!"

Why is this dead monkey so lucky! It is obviously my first! Whether it is business or land, it is my first! How can he attract Gao Li's attention with just one charcoal?

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

Twice! It's been two!

The first time, we negotiated with Gao Li in Yannan, signed an agreement, and accompanied the smile, and the dead monkey sold a sky-high price just by breaking the sell-off speculation!

This time, it was still the same. This dead monkey was obviously just here to fight Qiufeng, so he was not so loyal to Gao Li. But the result was that just because of this dark charcoal, he actually made a huge profit from Gao Li!

Although Ruan Weiwu does not know how important this coal mine is in Gao Li’s plan, it can be seen from their words that Gao Li is planning to focus on developing this place!

Ruan Weiwu felt very frustrated. This world is too unfair to him. Why does this world always bully honest people? Why can't I, a hard-working person, get rewards?

As the daughter of Ruan Weiwu, Ruan Suya understands what Ruan Weiwu is thinking at this time. Unfortunately, even she can't do anything about it. After all, this kind of thing depends entirely on luck, and Du Miao's luck is simply too good. I heard that Du Miao is addicted to gambling and likes to gambling, but nine out of ten gambling will even lose every gambling. Could it be that he actually got his luck back this time?

The next journey was very smooth, and no one came to cause trouble on the way. It seems that a devastating victory was enough to make those people understand one truth, that is, some people in this world are not easy to mess with.

When I came to the imperial city again, there was almost no change from last time. When I passed the city gate, what Gao Li saw last time was the same this time. Gao Li once saw half of the stone slab inserted into the gap and was about to fall. Today, it seemed that the half was still there. In other words, for so long, no one helped me to straighten the city gate. This usually means one thing.

The people in this city have no energy at all.

Of course, this does not even require a careful judgment to draw a conclusion. After all, these people look unhappy, and they have no hope for the future at first glance.

Gao Li was not here to be the savior. Looking at their appearance, Gao Li didn't have much emotion except shaking his head. However, the moment the car entered the city, he suddenly felt his ears buzzing. Then, he was filled with a sudden noisy sound. The sound seemed to come from his ears, or from deep in his mind, and it sounded like a dozen people were talking nonstop. The speed of the speech was very fast and the tone was particularly sharp. For a moment, Gao Li thought it was his tinnitus. But as he listened carefully, he could still understand some content. The content was not composed of any language understood by Gao Li, but it seemed to be automatically translated. Those voices should be quarreling about something, and the quarrel seemed to be divided into several sides. However, evenly matched, no one could convince anyone.

At the beginning, Gao Li only understood some vocabulary vaguely. But as he worked hard, he found that the more and more words he could understand, and more.

Then, he found that the quarrels between these voices were all aimed at him.

Some voices think that Gao Li is the enemy and must not communicate with him;

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

Some voices also believe that none of these matters, the key is to kill all the people in the Central Plains;

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

There was also a voice saying, you are all idiots.

Although the sounds were extremely chaotic, Gao Li still listened with relish. At this time, Gao Li was sitting behind the True Qi Car, with Du Miao driving in front, and Ruan Weiwu sitting in the co-pilot. Du Miao was very interested in all mechanical things, and the True Qi Car was no exception. This True Qi Car does not require an accelerator pedal, just inject the True Qi into the steering wheel, so even Du Miao can still control it. Moreover, he really has an amazing talent, don’t look at his first touching the True Qi Car. But after a few simple experiments, he can now control it freely.

It is precisely because of this that Gao Li has the opportunity to listen to their quarrel with you here.

Just in these voices, Gao Li suddenly heard a set of conversations: "Alruo, since you like these monkeys so much, you might as well take the initiative to become those monkeys, why bother among us?"

Then, he heard Elruo's voice: "If I like monkeys, do you want to become monkeys? You like to create death so much, why don't you die by yourself?"

Gao Li laughed loudly after hearing this, and couldn't help but say, "Beautiful!"

"who?"

"Who invaded our sea of ​​consciousness!"

"It's Gao Li! It's Gao Li! He can actually hear our voices and invade our sea of ​​consciousness. I just said that this person cannot be kept! He must be killed! Kill!"

Then, the noisy sound suddenly became quiet. No matter how carefully Gao Li listened, the sound would not appear. Then, in front of Gao Li, Alruo suddenly opened his eyes in a daze, and a purple light appeared from her eyes. She looked at Gao Li, then smiled and said, "Prince Gao is so powerful, even our sisters' sea of ​​consciousness can invade."

Gao Li said: "I don't have that ability. I thought it was similar to the voice that the residents of Yannan City could hear before."

Elruo said, "You didn't listen to it yourself?"

Gao Li said: "It must not be."

Alruo asked in confusion: "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 everyone in the city was surprised by the change of the crack. Then Gao Li and Elruo heard a low voice at the same time: "Because, I want him to hear what my daughters are doing."

The voice cannot tell the difference between men and women, or the age and the young. It is not even a sound, but a simple message. Just like the way Zulong communicated with Gao Li before, or the way a few daughters quarreled just now, this message was translated by Gao Li's brain and automatically converted into something he could understand.

"What's going on?" Ling Long noticed something was wrong and immediately grabbed Gao Li's hand.

"It's okay, I just heard the quarrel between their sisters." Gao Li said.

"Oh, I heard it too, but unfortunately the sound is too small and I can't understand it either." Ling Long said.

Gao Li nodded, then looked out the car window and said to the Ziguang who was catching up with him: "Are you the world, all evil mothers?"

"No, I am not all evil mothers. There are still some of my compatriots in the polar regions. They use the 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 and then said, "You can call me 'Gai'.

Gai, this name is very special. It is ten thousand yuan. Using this as a name must be quite confident in yourself.

"What you heard just now was the quarrel between my daughters. How much did you understand?" Gai asked.

Gao Li said: "I will understand from the moment they started discussing whether to kill me."

It was time to say, "How do you feel after listening to their words?"

Gao Li thought for a while and said, "I don't have much thought. After all, I don't expect everyone to like me. But of course, I can't allow others to just make up my mind."

Gai said, "Alruo should have told you my request, right?"

Gao Li said: "Yes."

"If possible, I hope you can kill two of them for me. They are my third daughter, Al-Jiu, and the seventh daughter, Al-Jiu."

Oh, so to put it, the child’s father’s surname is Al.

Gao Li smiled and said, "I was entrusted with such a great responsibility as soon as I 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, and I was going to risk my life to help you solve your troubles in front of me. I really feel, so scared!"

It is said: "I can understand your concerns. Of course, I don't plan to let you help you in vain. I will help you with the invasion of the eagle demon; I will help you even more by the invasion of the heavenly beings. In the past, evil strange invasions were essentially the actions of my two daughters. I can guarantee you that in the future, as long as they die, we evil strangers will never enter the Central Plains."

"The promise from the evil mother, I really want to know, what if you fail to abide by the agreement, can I do with you?" Gao Li said.

"I understand your caution, I understand your concerns. It is because of this that I found someone who is enough to prove me." Gai said.

"Who is it?"

"You will know when you enter the palace."

It's also mysterious, is this a puzzle adventure game?

The convoy stopped outside the palace and saw that it was Gao Li and the others. The Royal Guard, which had already lined up, immediately set up a formation to welcome Gao Li's arrival. Unfortunately, the number of people was small and the environment was very poor. It was the kind of person that you could tell at a glance that the royal family was quite poor.
