Six pipes are six ore search routines, and the late Han Dynasty used 'six pipes' to search for ore.

These six are from the Warring States Period's "Pipes and Places".

It summarizes the distribution law of minerals in some deposits, and points out that deposits can be found according to the symbiotic relationship between seedlings and minerals.

It has been used since the Warring States period, and it has not changed to this day.

But at this moment, it seems that something significant has changed.

A young man came up with a new theory of mineral prospecting, claiming that the theories that have been used for thousands of years are rubbish.

This made the three masters simply unable to accept the reality that they were garbage.

We are recognized as masters.

We have learned the technology for half a century, and this technology has been passed down for thousands of years, and it is actually meowing into garbage?

Doesn't it mean that the previous generations of masters are using garbage to find mines?

Even in the face of the lord, the masters were furious.

They all looked at Yuan Tan.

Do you think you're a master after summing it up? Is it okay for you to pretend to be realistic like this?

Although the saints are also sanctified after summarizing the hundred schools of thought, do you think you are a saint as a young man?

The three masters met and discussed.

"So, let's dig it!"

"If you can't dig it out, look at his face!"

"Let him know that maybe Taoluo literature can be self-taught, but if you mine, it's impossible!"

"The most important thing to look for is experience, what experience can he have at his age?"

At this time, a disciple walked out timidly.

Ma Lao looked at this beloved disciple, "Xiaolin, you have something to say, but it's okay to say it?" ”

Xiao Lin then said: "Teacher, two masters, are you thinking too much? The lord just read a few books and dug indiscriminately. ”

Well?

After the three masters glanced at each other, they all waved their big hands, "Start digging, go all out, and let the lord see his results as soon as possible." ”

Yuan Tan found that the momentum of the three masters was completely different from just now, and they all stood with their hands in their hands, looking at themselves proudly.

I'll go!

Yuan Tan couldn't let go, he didn't seem to be pretending to be forced, and he was kind enough to teach everyone the advanced technology of future generations.

But it seems that the three masters are going to pretend to be forced in front of him and want to slap him in the face. In this case, Yuan Tan said that he couldn't let them know what it meant to be a real pretend.

At this moment, he looked at Yuan Tan with cautious eyes, and thought in his heart, Lord, is there really a mine here? Why don't I have any confidence at all?

So, the barracks were settled, and nearly 100 people began to mine.

The elite miners held their breath and vowed to dig a hundred zhang in the shortest possible time, so that the lord would know that there was no mine at all.

Lord, you are bullish, we do not deny this.

But if you want to pretend to be in front of us miners, .......

This is a realm that a noble person like you can't touch at all.

Don't look at us as just miners, but in this field, only we have the final say.

The scene gradually became hot.

Speaking of ancient mining, it can be traced back to the selection of stone tool materials in the Stone Age.

Later, with the rise of metallurgy.

Mining and beneficiation technologies have also been gradually developed.

In the Spring and Autumn Period, vertical shafts, inclined shafts, and flat roadways have been used for joint development, and an underground mining system has been initially formed.

From the Warring States period to the Western Han Dynasty, the mining system was quite complete. General open-pit mining, underground mining, shaft support, rock crushing, shaft ventilation, and so on are basically perfect.

In the Eastern Han Dynasty, it was even more perfect, and there was no problem at all with the depth of the vertical shaft below 200 meters. Even if there is a geological problem, it is completely possible to continue to extend down in a stepwise manner after the slope.

The roadway support is solid, people can walk upright, and the excavation section is more than 5 meters.

Day 1.

Yuan Tan warmly invited the three masters to dine in his big tent.

He still loves these three old men very much, and in the future, it will be up to masters like them to look for minerals and train senior miners.

"Did you find a mine?"

Ma Lao saw Xiao Lin, a disciple who had closed the door, walk in and asked.

"There is no ......."

Xiao Lin spoke in a thin voice, which was caused by his forced joy.

"Hehehehe......."

The three masters looked at Yuan Tan.

"Hehehe......."

Yuan Tan looked back.

The next day.

"Did you find a mine?"

"Nope!"

Although the miners did not find the mine, they all became excited. How can we be so happy if we can't find a mine in vain?

Day 3.

"Did you find a mine?"

"Nope!"

The miners were even more excited, and it looked like the lord was going to lose.

Day 4.

After seeing the lord, do you dare to pretend to be forced in front of us miners.

Day 5.

The miners looked at the mine that had not been dug out with disgust.

Day 6.

We'll see you tomorrow!

The miners were like a big winner.

On the seventh day.

Yuan Tan had just finished breakfast, and when he looked up, he saw the three masters coming in with serious expressions.

The three old men bowed, and Ma Lao walked in as a representative, and said heavily: "Lord, whether you want to admit it or not, your prospecting has failed. ”

Wang Lao walked out, "My lord, we have dug down eighty zhang, we have carefully studied the soil quality, and there will be no mines at all." ”

Chen Lao walked out, "Lord, don't dig any more, time waits for no one." ”

"You've dug eighty feet?" Yuan Tan compared the stratigraphic data in the data, got up and said, "Dig three more feet." ”

What the!!! I'm going to dig it up!

The three masters looked over, lord, if you dig three more feet for the sake of face, it is purely a superfluous move.

Not to mention digging another three feet, it is another three hundred feet, and the result is the same.

It turns out that your theory is just like that Zhao Kuo, just on paper.

You didn't eat the first crab, but your mouth was full of bubbles by the pincers.

Don't you still admit that the theories summarized after reading a few random books are rubbish?

Ma Lao took another step forward and said lightly: "Lord, in fact, we have already dug three feet down to speak." ”

The voice did not fall.

Xu Chu walked in with a disgraced face, covered in mud.

Xu Chu is going to mine, he is infinitely powerful, thanks to his joining, mining is smoother.

In fact, the three masters were also persuading Xu Chu not to dig hard in the pit just now, it was useless.

Seeing Xu Chu come back at this moment, this must have given up.

Ma Lao immediately said: "My lord, General Xu has just returned from the mine, and you will know the result if you ask him." ”

"Have you mined?" Yuan Tan asked.

"I didn't ...... No. Xu Chu said patiently.

The grandmasters suddenly stood proudly, and they all looked at Yuan Tan, thinking, my lord, have you seen this general of yours? He's already given up, so you should give up this time, right?

"But I dug this, and there's a lot more down there, I don't know what it is!"

Xu Chu took out a huge piece of golden ore and roared excitedly.
