Huangfu Ming sent someone to send good news from the ancestral calendar hundreds of miles away, and he finally succeeded in digging out the black stone, and there was a small amount of gold.

Although winter has passed, the value of coal is still high.

Liu Yun was ecstatic, this matter finally had a sign.

He immediately sent a fast horse to send an order, from Ji County and Pingxiang, each of which transferred 1,000 city defense troops and 2,000 brave men to build a city in the Zuli Coal Mine.

The discovery of coal should be inevitable in Liu Yun's prediction.

It was an accident that gold was found, and it was definitely a great benefit that came with it.

In today's turbulent society, even the five-baht coin cannot be used, and it is directly bartered among the people.

But in the future, at least in Liu Yun's case, gold and silver will be the currency of the future.

Spending a lot of manpower and material resources to build a city and defend a coal mine is quite nonsense at the juncture when Liu Yun is about to encounter an economic crisis again.

But Liu Yun felt that this thing had to be done, and the absolute value there was in front of him.

In a turbulent society, if you don't take such a crude and primitive way to protect your property, it is very likely that you will be robbed in a blink of an eye, which is not uncommon at all.

Whether it is coal or gold, minerals occupy an absolutely pivotal position in the entire economy and society.

As soon as the coal mine starts to be mass-produced, the efficiency of all the workshops on Izumo Mountain will definitely double exponentially.

This will be the beginning of industrialization and the premise for the reform-style development of productive forces.

So, Liu Yun began to write books for Zhuo Gang again.

Writing hard couldn't suppress his surging mood, and things were going much faster than he expected.

Liu Yun told him everything he knew about the use of coal.

But alas, none of them are detailed and clear.

Liu Yun knows what coal can be made of and where it can be used, but he really doesn't know how to do it in detail.

These detailed processes are still old rules, and they can only be pondered by the hundreds of craftsmen led by Zhuo Gang on Izumo Mountain.

Liu Yun's hands-off shopkeeper is actually not easy, but it is quite tiring.

When Wang Zhi came, Liu Yun hadn't slept well for about three days, and the table in front of him was full of all kinds of manuscript papers.

At a glance, there is a feeling that having paper is capricious.

"My lord, the last general is really suspicious sometimes, what is your head made of? Why can't you read a single word of what you write? Wang Zhi probed over, glanced at the things Liu Yun wrote, and couldn't help muttering.

Liu Yun threw down the brush, rubbed his eyes and yawned, and scolded angrily: "Can your uncle speak?" How can I hear that you mean to cut off my head? I can't understand it's because you're stupid, and if you're not right, I think you're having some bad intentions. ”

Wang Zhi smiled, and said with a smiling face: "Lord, a slip of the tongue is a slip of the tongue, it's really a slip of the tongue!" I've just finished reading the military merit book, and there are a bunch of heads in front of me. Originally, I wanted to say that the lord was wise and martial, but as soon as his mouth was scooped, he became the head. Don't blame the lord, don't blame, I was wrong! ”

"The desire to survive is not very strong, and it seems that I am a little too good to you." Liu Yun yawned, tears flashing in his eyes, and muttered.

Wang Zhi was taken aback, and said bitterly: "Lord, I really didn't mean it, this ...... It was an accident, a real accident. ”

A tendon head is always not so easy to turn around.

This accusation in a hurry reveals a thick tendon.

Liu Yun waved his hand and said with a sleepy face: "Okay, I can't see any good words in your stupid mouth, what's the matter?" Go ahead. ”

Wang Zhi breathed a sigh of relief, as if he had been pardoned.

With a little embarrassment in his expression, Wang Zhi said: "What the lord said is really too appropriate, the last general is not only stupid, but also stupid, so I have to come to bother the lord in order to get the truth." ”

"Don't fill me with ghee here, I'm sleepy and sleepy. I haven't seen you for a few days, and it's said that you're training, so it's not like that, right? Liu Yun lazily leaned back in the chair and asked.

He was really sleepy now, his head was a lump of mush, and he was crying out a voice: Sleep!

When Wang Zhi heard this, his eyes suddenly lit up, nodded again and again, and said: "The lord is really discerning, and the little thing that the last general has done has not escaped the eyes of the lord who is watching the fire." Lord, I can't hide it, the last general has indeed been training recently, but because he is really stupid, he has never been able to ask for the law. The last general didn't understand why Jiang Zheng was able to train his subordinates to become such dragon spirits and fierce warriors, but I was a mess......"

"You're really good, but you're right, you're really stupid! I have taught you all the methods of military training, there are many methods, I only know that there are some methods, but I have not practiced them, so let them choose what they think is suitable and suitable, and then apply them to actual exercises. ”

Liu Yun yawned two more huge times in a row, and began to attack with an unhappy face.

"Besides, how long has Jiang Zheng been training? How long have you been practicing, and if you don't put time and energy into one thing, no matter how much you get the essentials, you may not have a good effect. It's only been a few days, and I said impatiently no, you are looking for what the problem is! ”

"On the real training ground, go to my problems with those methods, test the methods with practice, continue to deepen the training if it is right, and change it immediately if it is wrong, this is the most correct. I'm not smart, and I don't have any scriptures to give you, and the scriptures that should be given have already been told to you, and that's all there is to it! That's a method from 2,000 years later, and it's very advanced. ”

There are many ways to train soldiers, and Liu Yun has seen a lot of them, thanks to various film and television dramas.

He can write a rough idea, but he really can't actually do it.

In the entire Hanyang Army, only Jiang Zheng was really successful.

How Jiang Zheng succeeded is probably what Liu Yun just said.

Wang Zhi, the old boy, wanted Liu Yun to teach some more tricks, and he would also teach a hammer.

When theories are applied to practice, even those who write these theories must be confused and make mistakes.

Wang Zhi's eyes widened more and more when he heard this, and this damn, magical scene happened again.

He began to understand again, what theory is applied to practice, what is tested by practice, and after 2,000 years, what is this?

Wang Zhi was stunned!

His head seemed to be packed with a ball of wool, and Wang Zhi's eyes were full of confusion.

"My lord, I ...... Ponder a little, ponder carefully. ”

Wang Zhi stretched out his hands, and seemed to use all the strength to grow so much, and his muscles burst into understanding these words.
