"Father, the current situation is turbulent, is it a little inappropriate for you to go out for a private visit at this time? If something is in danger..."Before Zhu Di finished speaking, he was interrupted by Zhu Yuanzhang waving his hand.

"It's because of the turmoil that I want to go out for a walk, and I want to see if these civil and military officials under my command are doing their duty!" Zhu Yuanzhang looked at the crown prince Zhu Di, his eyes showed a trace of worry, but it quickly flashed: "However, this is also a test for you, it is time for you to try to take charge of the people and things above the court, and establish your prestige as soon as possible." ”

Zhu Di also saw that Zhu Yuanzhang was serious this time: "Yes, father, the son will not disappoint his father!" ”

On the Yang Mansion, Yang Xiyuan called Luo Wen back, since Luo Wen was sent to secretly train the dark department, this is the first time in such a long time to return to the Yang Mansion to see Yang Xiyuan.

"Sir, what do you command?" Luo Wen is now wearing this jet-black robe, which is lightly embroidered with golden dragon scales, which is also the costume of the dark part designed by Yang Bing.

Yang Xiyuan took out the token that represented the commander of the dark department: "Send this to Yang Bing's hands, and in the future, the dark department will be directly commanded by him, and Your Majesty will dictate the imperial power to give permission, first cut and then play!" ”

Luo Wenyan's hands trembled when he heard this, and taking the token meant that the dark department was truly established, and he could fight side by side with the young master again.

"Yes, master, Luo Wen must personally deliver the token to the young master!" After speaking, Luo Wen was about to go out.

Yang Xiyuan opened his mouth and stopped him: "Wait a while!" I'm so anxious! ”

Luo Wen came back and laughed.

Yang Xiyuan hesitated again and again, and finally looked at Luo Wen and asked, "Luo Wen, what do you think of the young master's temperament?" ”

Luo Wen was stunned for a moment, and then replied: "The young master's heart is naturally excellent, although he did some ridiculous things when he was young, but recently, I believe that the master has also seen the young master's skills." ”

Yang Xiyuan nodded, in fact, he also thought so, but he just wanted to hear the confirmed voice from other people's mouths, Yang Xiyuan turned around and walked to the top of the bookcase, picked up a long box and handed it to Luo Wen, and instructed: "Bring this to Yang Bing as well, and tell him that this matter is up to him." ”

Although he didn't know what was inside this box, Luo Wen knew that this thing was more important than the token in the shadows.

The Tongtian Pass in winter has now been changed to the City of All Nations, which means that all countries can come here to trade, and no conflicts are allowed, even if there have been conflicts before.

However, now there are some thorny problems in front of Yang Bing, that is, the heating problem of the people.

Since Lin Ziren's rebel battle, the supplies of Wanguo City have almost been exhausted, and everyone's heating in winter depends only on the dry firewood saved in autumn.

Now there are many poor people, and some people have frozen to death.

"Lord Yang, this is the only refined coal left in the city." Guan Shiru took the account book and said to Yang Bing with a sad face.

After escaping from Qiling Mountain last time, Guan Shiru made up his mind to follow Yang Bing, not only because of Yang Bing's cultivation of external injuries, but also because Guan Shiru saw Yang Bing's strategy and the city government.

Therefore, after Guan Shiru learned that Tongtian Pass was changed to Wanguo City, and Yang Bing stayed here, he came over to Yang Bing, and Yang Bing also found that Guan Shiru also had some talent in mathematics, so he ordered him to be the head of the logistics department.

Guan Shiru didn't understand what it meant when he heard the logistics department, but it was only under Yang Bing's explanation that he understood the importance of this position.

When Guan Shiru took office, he coincidentally caught up with the cold winter, which was the coldest winter in Tongtianguan in recent years, he was going to show his skills and distribute all kinds of materials, but it turned out that there were only forty cars of refined coal left in such a large Tongtian Pass, which can make Guan Shiru and Yang Bing sad, you must know that in this era, if there is no refined coal, it is impossible to survive the cold winter, coupled with the geographical location of Tongtianguan, the winter is two months longer than the Central Plains, and many people have been frozen to death during this time.

"Is that all there is left?" Yang Bing picked up a piece of coal and observed it carefully, it was indeed a high-quality coal: "On weekdays, the refined coal is dug from there, have you found it out?" ”

Guan Shiru replied seriously: "Lord Hui, they are all in the mines in the west of the city, but according to the officials in the past, more and more waste coal has been produced in the mines in recent days, and refined coal is almost gone." ”

Yang Bingyan was puzzled when he heard this: "Waste coal? Coal? Is this also divided into waste coal? ”

Guan Shiru was also stunned, didn't this adult know about waste coal? It shouldn't be.

"Lord Hui, this waste coal cannot be burned, once burned, it will produce poisonous gas, the light one will be unconscious, and the heavy one will die directly in Huangquan."

When Yang Bing heard Guan Shiru's words, he suddenly remembered a possibility, and immediately said, "Take me to that mine." ”

Guan Shiru didn't understand that a mine full of waste coal was what to see, but since the adults had spoken, they could only do it, and hurriedly ordered their subordinates to prepare the carriage.

This mine in the west of the city, half of the mountain is in the city, half of the mountain is connected with Qiling Mountain outside the city, when Yang Bing came here, he saw that many miners were struggling to dig the coal mine, but one by one they were depressed, dug out a few pieces of coal and took a look, and they all sighed and threw it away.

Yang Bing walked over and picked up the waste coal that was thrown on the ground and observed, an elderly miner on the side saw Yang Bing, a young man dressed luxuriously, picking up the waste coal, and thought that he was a rich man in the city who came to buy coal: "Boy, don't think about it, it's all some waste coal, and there is no refined coal in this mine for a long time." ”

Yang Bing didn't speak, but looked at the waste coal in his hand very fascinated, and Guan Shiru on the side opened his mouth and said to the old miner: "This is Lord Yang Bingyang!" Be careful when you speak! ”

When the old miner heard Yang Bing's name, he didn't do anything but didn't care: "Lord Yang? And out of nowhere, there is a Lord Yang, but he was sent down from Kyoto to gild, what can he do? ”

As soon as the old miner's words fell, a miner on the other side who looked very young heard Guan Shiru's words, and glanced at Yang Bing, who was squatting on the ground looking at the coal mine, and suddenly shouted loudly: "It's Lord Yang!" It's really Lord Yang Bingyang! After speaking, the young miner came to the old miner and reminded: "This is Lord Yang Bingyang, who retreated from 100,000 rebels a few days ago!" ”

When the old miner heard the young miner's words, he was stunned for a moment, and then his cloudy eyes showed an excited look: "Lord Yang! ”

Hundreds of miners behind him came to their knees.

But Yang Bing seemed to be enchanted, and he still looked at the waste coal in his hand.

Everyone looked at Yang Bing blankly, and even Guan Shiru didn't figure out what Yang Bing was going to do, so he could only wait for Yang Bing to come to his senses.

After about a quarter of an hour, Yang Bing suddenly jumped up from the ground and shouted, "I'll go, this coal mine is good!" The best of the best! Lao Guan, go and order someone to find such a coal mine, the more the better! ”

When everyone saw Yang Bing's appearance, they were dumbfounded, and said in their hearts, Is this Lord Yang crazy? Take scrap coal as a treasure?

Guan Shiru said cautiously: "My lord, this is just a piece of waste coal, what do you want it to do?" ”

Yang Bing only found out about everyone's appearance at this time, and was also taken aback: "What are you doing in a daze!" Dig me up! If you don't dig enough, you, yes, yes, just you, I'll ask you! Yang Bing pointed to the young miner who had just spoken.

The young miner pointed to himself, looked around, and immediately felt a sense of pride in his heart, obviously Lord Yang has made me an official!

"Yes, Lord Yang, look at it!" The young miner turned around and immediately put on a dog's leg, crossed his waist and picked up a piece of abandoned coal mine in his hand and said: "See, Lord Yang has spoken, just look for such a dig, the more the better!" ”

The miners didn't know why they were digging up the waste coal, but the adults had spoken, and they could only do it, only the old miner muttered: "Alas, it seems that this Lord Yang is good at fighting, and he can't look at coal, and he thinks he is a shrewd adult." ”

Coincidentally, this sentence was heard by Yang Bing, and immediately called the old miner over, and the other miners were worried about the old miner, after all, most of the generals from the military camp were very short-tempered, and they were afraid that Yang Bing would cut the old miner directly if he was in a hurry.

The old miner was not afraid, straightened his waist and walked in front of Yang Bing: "What do you have to do?" ”

"That's what you just said I don't know about coal?"

"I didn't say it myself, my lord, you can ask everyone if the coal in your hand is scrap coal." The old miner said proudly, with an expression on his face as if he was talking about a little hairy child, how old are you?

Yang Bing was not angry, smiled slightly, and then ordered Shiru to bring a basin of clean water, and then threw a lot of waste coal into it, rolled up his sleeves and reached out in the surprised eyes of everyone and began to wash the coal.

Guan Shiru felt that going on like this would damage Yang Bing's image, so he dispersed the other miners, leaving only the old miner.

After washing for about half an hour, Yang Bing stood up and poured out the water in the basin, and the remaining coal mines in the basin actually shimmered the luster of refined coal under the sun, which shocked the old miner who had been digging for decades.

"This, this has become refined coal?"

Yang Bing shook his head: "Actually, the coal mines in this mountain can be used, but in the past, there are relatively few impurities in the refined coal that you dug out and can use, and the so-called waste coal in your mouth is actually like a flower bone that has not yet bloomed, we only need to clean out the impurities with water, and it will become refined coal." ”

This is the advantage of a traverser, who can easily use his knowledge and skills to create something that is not available in the current era.

The old miner couldn't believe that he picked up the coal mine that had not yet dried and wanted to throw it into the fire, but was stopped by Yang Bing: "Old man, I know you are very anxious and want to test whether this coal can be burned, but now there is still one step away, that is, the sun, after enough time, the mine you see can be burned!" ”
