Huangfuming sent people to send good news from his ancestors hundreds of miles away. He finally successfully dug out black stones and a small amount of gold.

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

Liu Yun was ecstatic, and there were finally signs of this matter.

He immediately sent a quick horse to send an order, and from Ji County and Pingxiang, he dispatched 1,000 city defense troops and 2,000 brave men to build a city in Zuli coal mine.

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

It was an accident that he even found gold, which was definitely a great benefit with gifts.

In today's turbulent society, even Wuzhu coins cannot be used, and they are directly bartered among the people.

But in the future, at least for Liu Yun, gold and silver will definitely be the currency of the future.

It is quite nonsense to spend a lot of manpower and material resources to build cities and guard coal mines when Liu Yun is about to encounter another economic crisis.

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

In a turbulent society, if you don’t use this rough and primitive way to protect your property, you may be robbed in a blink of an eye. This is not a rare thing.

Whether it is coal or gold, minerals play an absolutely important role in the entire economic and social society.

As long as the coal mine starts to enter mass production, the efficiency of all workshops on Izumo Mountain will definitely double.

This will be a sign of industrialization and a prerequisite for the reform-oriented development of productivity.

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

Even if he was writing hard, he couldn't suppress his surging mood. Things were developing much faster than he expected.

Liu Yun talked about everything he knew about the use of coal.

But unfortunately, nothing is detailed and clear.

Liu Yun knew what coal could be made and where it could be used, but he really didn't know how it was made in detail.

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

Liu Yun, the boss who is a hand-off, is not easy, and it is quite laborious.

When Wang Zhi came, Liu Yun had not had a good sleep for about three days, and the table in front of him was full of various manuscript papers.

I glanced over at a glance and felt that there was a feeling of paper being willful.

"Lord, sometimes I really doubt what your head is made of? Why can't you even understand a word of the things you wrote?" Wang Zhi poked over, glanced at the things that Liu Yun wrote, and couldn't help but mutter.

Liu Yun threw down his brush, rubbed his eyes and yawned a big yawn, and cursed in anger: "Can your uncle speak? Why do I listen to your words and mean to chop my head? I can't understand it because you are stupid and say something wrong, and I think you have some ill-thinking plans."

Wang Zhi smiled and said with a smile: "Lord, the tongue is wrong, it's really a tongue! I just finished reading the military achievements, and there were a bunch of heads in front of me. I originally wanted to say that the lord's wise and powerful head, but after a mouthful, it became the head. Lord, don't blame me, don't blame me, I was wrong!"

"I don't have a strong desire to survive. It seems that I'm a little nice to you." Liu Yun yawned, tears flashing in his eyes, and muttered.

Wang Zhi was startled and said bitterly: "Lord, I really didn't mean it. This... is really an accident, really an accident."

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

The accusation in desperation revealed a strong tendency.

Liu Yun waved his hand and said with a sleepy look on his face, "Okay, I can't say anything good to listen to in your stupid mouth. What's the matter? Tell me."

Wang Zhi breathed a sigh of relief, as if he had received an amnesty.

With a little embarrassed expression, Wang Zhi said, "What the lord said is really appropriate. Not only is he stupid, but his head is also stupid, so he has to come and trouble your lord to seek the true scriptures."

"If you have something to say, don't give me butter here. I'm so sleepy that I'm still busy sleeping. I haven't seen you for several days. It's said that you are practicing troops. This is not the case, right?" Liu Yun lay lazily into the chair and asked.

He was really sleepy now, his head was a mud, and he shouted: Go to bed!

When Wang Zhi heard this, his eyes suddenly lit up, nodded repeatedly, and said, "My lord is really aware of his bride. The little things that Mo Jiang did have failed to escape the lord's gaze of the hidden fire. The lord, it's not to be concealed. Mo Jiang has indeed been practicing troops recently, but because he is really stupid, he still can't figure out the key. Mo Jiang didn't understand why Jiang Zheng could train his division into such a dragon spirit and a fierce tiger, but I'm all a mess..."

"You are really not a good thing about flattery, but you are right, you are really stupid! I have taught you all the methods of training troops. There are many methods. I just know there are some methods, but I have never practiced them, so let them choose what they think is suitable and suitable, and then apply it to actual practice."

Liu Yun yawned two huge yawns in a row and began to criticize with an unhappy look.

"Besides, how long did Jiang Zheng practice military training? How long did you practice? If you didn't put your time and energy into something, no matter how you got the key points, it might not be as good as possible. After only a few days of work, you were anxious and irritable and said, "No, you are looking for the problem?"

"In the real training field, go find my methods and use practice to test them. If you are right, continue to deepen your training and correct them immediately. This is the most correct one. I am not smart nor have any scriptures to give you. I have told you the scriptures I should give, and that's all those things! That's the method that comes from two thousand years later, and it's very advanced."

There are many ways to train troops, and Liu Yun has read a lot, all relying on various films, TV series and novels.

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

Jiang Zheng was the only one who really succeeded in the entire Hanyang army.

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

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

When the theory is applied to practice, even those who write these theories will be confused and make mistakes.

Wang Zhi's eyes widened as he heard it. This damn, magical scene happened again.

He began to lose his understanding again. What theory should be applied to practice and tested theory with practice. What will happen in two thousand years?

Wang Zhi was confused!

His head seemed to have a ball of wool filled it, and Wang Zhi's eyes were full of confusion.

"Lord, I... think about it a little, think about it carefully."
