The corners of Li Yi's mouth twitched on the side, this elder brother knew how to prevent collapse, and knew how to prevent poisonous gas from hurting people, but he didn't say it until the excavation was confirmed, and the people who died in front of him were really wronged.

Feng Tu said he was not responsible for the incident.

If he hadn't died so many people, he wouldn't have thought of these measures!

He's not a coal boss.

And he was also very distressed when so many people died.

With such a shortage of labor, can you not feel distressed?

But it's still that sentence, civil engineering, how can there be immortals?

In later generations, science and technology are so developed, isn't there still a mining disaster every year?

Thinking of this, Feng Yong turned his head to Li Yi and said, "Wen Xuan, Erlang, is there any news coming back?" This manpower is not enough! ”

More than 500 Di people were taken prisoner, dozens of brick kilns collapsed and crushed to death, coal digging collapsed, and more than 100 people died, and now there are less than 400 people left, which is indeed not enough.

"Brother, last time I only said that General Ma was ready to go, but I didn't mention where to go, and so far, there is still no news. The little brother looks at digging this charcoal, and it doesn't take many people, how can it not be enough? ”

"It's right not to mention where to go, the march needs to be kept secret, and if it is not secret, it will be defeated."

Feng Yong nodded and continued to explain to Li Yi, "It doesn't take many people to dig up this charcoal, but to dig it up, you have to wash, burn, and stir, and there are many people who use it." ”

"Wash?"

Li Yi was a little confused, "Washing charcoal? How to wash? Isn't it possible to burn charcoal directly? Why wash? ”

"Of course, the charcoal can be burned directly, but it is not easy to burn. If you stir it into a mud with water first, you can separate the useless impurities in it, and you will get better charcoal, and such charcoal will be easy to use when it is burned. ”

Coal washing, the sunset industry of later generations, the main operation method of Xiaohei Coal Mine, you can know the process of how to do it at a glance.

It only takes one arm of strength, and the rest can be done without brains, which is almost the same as playing with mud.

Most of the impurities washed out are coal gangue, which is used to burn bricks and fill roads in later generations, which is very common and can be regarded as waste utilization.

But it also has a very important use, that is, it is used to make clinker-free cement.

In later generations, many of the illegal small black coal mines and houses in the mines were built by burning bricks and making cement by themselves.

Coal gangue can be used to fire bricks, and the quality is better than that of clay.

The burned coal gangue is ground into powder with lime and gypsum in a certain proportion to obtain a thing called clinker-free cement.

It can be called cement, but the strength is very low, and it can only be used for bricklaying, as a binder, not as concrete for high-rise buildings.

The so-called tofu slag project, in addition to the use of bamboo bars instead of steel bars in the project, may also use this kind of cement.

No way, it's cheap!

Which small black coal mine has not engaged in this kind of cement?

Otherwise, how can you call the black-hearted boss of the black coal mine?

This kind of cement, in the eyes of later generations, is slag, and should not exist in the world.

Coal gangue, in terms of making cement, should replace clay and make qualified products of various grades.

But Feng Tujiao said, damn it, I don't know how to burn cement, and finally I have a kind of cement that can be calcined without calcination - let's call it cement - why not use it?

Anyway, I don't use it to build a high-rise building, build a small bungalow or something, isn't it too much?

Nanxiang County also has the largest gypsum mine in Asia, with two large-scale first-class limestone mines, plus this coal mine, if you don't use it to make cement, this will be a thunderbolt?

In this era, it's good to have cement, but what do you want?

So, how can the 400 or so people on hand be enough to fill the bottomless pit?

As for the washed coal, in addition to burning it for himself, he sent it to Hanzhong Metallurgical Iron Smelting, so he is also the second in command of Hanzhong Metallurgy.

At that time, the amount of iron produced by Hanzhong Metallurgical will skyrocket, and I don't know if the old demon Zhuge will show the kindness of his elders again and let Adou let this Hanzhong Metallurgical out?

But that's something that the queen and Adou have to worry about, and it has nothing to do with them.

"Adults spare their lives, adults help me!"

Rimai Muxi wore a cloak of tears, knelt in front of Zhao Guang, and kowtowed again and again.

Zhao Guangma sat on the main seat of the camp tent with a golden knife, and Wang Xun sat next to him.

The two of them came to Yang'an Pass with their subordinates, nominally to see if there was a suitable place for cattle and sheep or farming, but in fact they came to be traffickers.

And the kind of traffickers that both adults and children, strong women, want.

After all, it was a person sent by the captain of the Hanzhong Dian Agricultural School, and General Ma naturally wanted to cooperate, so let the two of them lead the ministry alone and become their own in the army.

"Please, my lord, let our people go!"

Rimai Muxi was already bleeding from his forehead, but he still didn't dare to pause a little.

Zhao Guang propped one hand on his knees, pointed at Wang Xun with the other, stretched his feet to the side of Rimai Muxi's head, and sneered: "Rimai Muxi, you can see clearly, this one next to me is my brother." ”

Rimai Muxi paused, looked up at Wang Xun, there was some horror in his eyes, his lips squirmed a few times, but he couldn't speak, he just continued to kowtow violently, "My lord, spare my life, my lord!" ”

Zhao Guang smiled, sat up straight, and said lightly: "A few months ago, my brother's lord ran all over the mountains in order to beg you to help my brother graze, but how did you treat this uncle in the first place?" And how do you say that? ”

"My lord, a lot of people have died in the Winter Clan this year, and the rest can't eat, please, just let us graze around here, let's exchange some food."

Rimai Muxi didn't dare to answer Zhao Guang's question, he was just muttering to himself, and the blood on his forehead ran down his face, dripping to the ground, splashing dust.

Zhao Guang snorted, "At the beginning, my brother was kind enough to ask you to help, but not only did you not accept it, but you also treated my uncle like that." What else are you talking about? said that there are not many Han people in Hanzhong, and you still have to take your clansmen to Hanzhong and kill all the Han people? ”

"Don't dare, adult, villain don't dare!"

Rimai Muxi trembled all over, and tears flowed down his eyes.

"You also said that a big official in Hanzhong was killed by your Qiang people in the past, and you plan to do the same in the future, right?"

Zhao Guang sneered, "Come on, I'm an official anyway, just sit in front of you,"

As he spoke, he threw a horizontal knife in front of Rimai Muxi, "Pick up this knife and stab it directly, let me see the courage of your Qiang people." ”

"Don't dare, adult, villain don't dare!"

Rimaimusi wept and muttered the phrase as the blood began to seep into the dirt.

There was an old man standing next to Zhao Guang, his eyes were half-open and half-closed, occasionally revealing a fine light, this was the old man of Zhao Mansion who came from Jincheng some time ago.

Wang Xun looked at the head of the tribe in front of him, and his heart was happy.

The adult was wronged a few months ago, and he almost knelt down to beg for help, and among them, there were all kinds of ridicule from this person.

As a son, he wanted to kill him directly to relieve his hatred.

Unexpectedly, it was only a few months later, and he had to kneel in front of him, like a guinea dog waiting to be slaughtered.

It's much more refreshing than killing him on the spot.

Think about my brother again, although I haven't seen him kill anyone with his own hands, but how long has he been in Hanzhong, and how many people have died because of his brother?

And there will be more in the future, because my brother has already sent a letter, so let them think of getting some more people as soon as possible.
