When Yu Zhigan returned to Chang'an again, it was already ten days later. It took him more than twenty days to go out. The situation in Tongxian County was basically stable, and the rest was to wait for the beginning of spring.

The football match was also held perfectly. In the past, football matches are basically just watching people hit people, and there is no technology at all. Some wounded people have been produced, but it has also made the group of victims safe.

"Football is still not good, it's too easy to get hurt!" Yu Zhigan sighed. He was still too naive. He followed the way in several novels he had read, but he ended up falling into a pit.

"Let's study the rugby after you go back. Rugby is simpler and more suitable for the current situation. At least it won't kill people, and they all have thick skin and can't get into trouble. If you break your legs, it will be really dead!"

More than 20 people were injured during the disaster relief, all of whom were playing football. Regarding this, Yu Zhigan felt that he must reflect on it carefully. He could not copy anything. The best one was suitable, such as the last Xishan Oolong and this football accident!

"Oh, knowing mistakes can improve a lot. I am indeed an excellent person..."

Yu Zhigan sat in the carriage and praised his excellence!

It took more than 40 miles to travel, and it took three hours to come from Tongxian to Chang'an. This was because the ground was frozen for several days in a row. Otherwise, it might be longer. The ancient roads were really hard to describe!

"With cement, if the spring next year, you should also build the road. First, the official road will be repaired. This will make the traffic much better. It seems that you need to find a reason to fool the Ministry of Revenue to build the road. It is best to be able to bring it to the Ministry of War. Otherwise, it would be too much of a loss to build the road by yourself. There are no toll stations these days, so you can't recover the cost of building the road by yourself!"

Yu Zhigan looked back at the bumpy road surface and said to himself, from Tongxian to Chang'an, this is the best road in this era. Except for the official road, the rest of the road is almost impossible to leave once it rains.

Chang'an City is still the same, and there are always people queuing at the door. Even if it is winter and the roads are muddy, there are still people coming from outside the city, queuing in the cold wind, waiting to enter the city.

Someone with some eyesight, when he saw the four-clawed golden dragon flag standing in front of the prince's frame, he immediately made way and stood on both sides and whispered.

"The prince has returned to the city! Where did he go?"

"I went to Tongxian to provide disaster relief!" This is a Shandong man who likes to turn the sentences!

"Have you heard that the prince showed up in Tong County's disaster relief and saved the dead. He heard that the person he saved had secretly learned the things of His Highness the Prince!"

"The prince is really a good person!"

"I am lucky to be in the court. Your Majesty is wise and the Crown Prince is wise. There is still hope for this day..."

“…”

Yu Zhigan heard the discussion outside and touched his handsome face. He was very curious about how traffic was so closed in this era. How this gossip news was conveyed and circulated, just like in later generations, the way of jumping rubber bands seemed to be universal across the country...

However, Yu Zhigan soon discovered a more magical scene. After entering Chang'an City, he found that many people had a small bamboo chimney in their houses, with smoke coming out of them, and there were more than one, and there were quite a few.

When the carriage passed by a house with the door open, Yu Zhigan found the coal stove. Yes, Yu Zhigan read it correctly. He saw the coal stove in a house in Chang'an City, and it was burning.

Where did the coal stove come from? Where did the coal come from? Why did anyone use a coal stove in Chang'an City? Have you traveled through it by yourself? A series of questions kept popping up in Yu Zhigan's mind!

"Chen Qingzhi, have any merchants from Chang'an gone to Tongxian recently?"

Only the people in Tongxian know about coal stoves. Recently, many people have used them. There is not enough coal, so some wood is temporarily burned.

"Some merchants went to Tong County to sell some items, but the number was not large. They all came to sell food and winter clothes!"

"Did they buy that coal stove?"

"This is not clear, but Tongxian coal stoves are basically booked, and the queues are all within the next month. Even if these merchants want to buy them, they shouldn't be able to buy them!"

"Then look at how many smokey places are in Chang'an City!"

Chen Qingzhi then realized that this place is Chang'an, not Tongxian. He didn't feel that he saw these chimneys before. After all, Tongxian is full of these chimneys, but it is different in Chang'an. How could there be so many chimneys in Chang'an City?

"Your Highness, this..."

"Go back to the palace first!"

"Here!"

In the palace, the emperor was reviewing the memorial, and Jing Ke reported below: "Your Majesty, it has been found that there is a coal mine near Yong'an Town around Chang'an City. The number is unknown. Bingzhou and Daizhou have been found to have a large number of coal mines!

"Oh, there are a lot of coal mines?"

The emperor looked happy. After receiving the report, Yu Zhigan found coal, he immediately asked someone to get some. He found that this black stone could actually burn. He immediately knew how effective this thing was, and immediately began a nationwide investigation!

"Yes, the number is huge. The rest of Xizhou and Shuozhou are being investigated, and the situation is currently unknown!"

"Well, I understand, the prince is back today!"

"The frame of His Highness the Crown Prince has entered Chang'an!"

"Be careful this time, don't be found by the prince!"

"Here!"

After the emperor finished speaking, he thought about whether he should give the prince some reward. After all, the inner palace is rarely more abundant, so he should spend a little, but what is the best reward?

After thinking for a long time, the emperor didn't expect it. Finally, he shook his head and verbally rewarded him for the time being. He would talk about it later.

"Alang, what are you laughing at?"

At the dinner table, the queen looked at the emperor who was laughing while eating and asked in a low voice.

"Well, the prince is back, I'm happy!"

The queen also smiled: "Gan'er has grown up, and it's different from before. Now she can stand alone. I heard that Gaan'er has done a good job in Tongxian this time?"

"Yeah, very good!"

The emperor nodded, and waved his hand at this time. A little eunuch walked in with a gift box, containing a string of pearl necklaces.

"Alang, is this?"

"Thank you for your hard work over the years!"

"Thank you, Alang..."

The emperor has been very rich recently, and this is something that all the concubines in the kilometer know. Today I will give a concubine a glass mirror and tomorrow I will give a glass jade pendant. Even if I play mahjong, I will make more than ten taels of silver. This was very rare in the past, and after losing money, I didn’t throw a tantrum, but instead smiled!

The queen looked at the pearl necklace and looked at the emperor, as if she understood something, and slowly spoke: "Did Alang steal some business again?"

"No, I just feel that my godfather has indeed grown up and need to know that some sinister things are happening in the world!"

After saying that, the emperor continued to eat without saying anything. After hearing this, the queen sighed. It seemed that Yu Zhi must have done something good for the emperor to hold.

In the East Palace, Yu Zhigan listened to Chen Qingzhi's report: "Your Highness, you have found out that the merchants selling coal stoves are all ordinary merchants. They seemed to have gone to Tongxian a few days ago..."

"Um?

Yu Zhigan was stunned for a moment. Didn’t his father do it? After being cheated by his cheap father for a long time, Yu Zhigan’s first reaction was to be cheated by his father. After all, he had just developed something and had not spread it yet, someone had already made it. In the world, except for Emperor Yu Zhigan, there was no one else in the world.

"Is it a coincidence?"

Yu Zhigan thought about a possibility, that is, after these businessmen came to Tongxian, they discovered the coal stove, and then discovered the business opportunities. After learning a rough idea, they came to Chang'an City to burn it themselves, and then...

Although the time is a bit short, there is also this possibility. After all, the fire cellars around Chang'an City can be combined to circle Chang'an City twice, work overtime and then make a lot of publicity.

"But it wouldn't be such a coincidence, right?"

Yu Zhigan was still full of doubts, but then he thought that he could have made a book by chance, and maybe that was just a coincidence.

"Well, I need to continue checking. I feel it's not that simple. I'll also see if there are coal mines near Chang'an and where there are coal mines, so I'll buy them first!"

After hearing this, Chen Qingzhi thought for a moment and spoke slowly: "Your Highness, coal mines have been discovered around Chang'an City, in Yong'an Town!"

"Did you find it? Can you buy the coal mine?"

"Your Highness, that land has been bought by someone. Oh, by the way, it was bought by the Duke of Qi..."

“???”

Yu Zhigan was stunned for a moment and was bought. Duke of Qi? Isn’t Duke of Qi Yuchi Gong’s family? Why did this guy buy this piece of land?

"I'll go to the palace first. You'll prepare some gifts and give me a message. Wait until I come back and go to the Duke of Qi!"

"Here!"

Yu Zhigan was full of doubts, and there were also Tongxian's specialty, Bear Paw, to be precise, the giant panda's bear paw. Tongxian was not far from the Qinling Mountains. It was snowing during this period, and many pandas came to find a way to find a panda leather jacket to wear. Many of them were killed. Yu Zhigan was also kept in the East Palace and was preparing to find an opportunity to make a panda leather jacket.

It is impossible to raise pandas. This thing is now large in number and can be eaten. With the current financial and material resources of the East Palace, if you keep one, it will be not far from bankruptcy...

"My son has met my father!"

In the hall, the emperor who had just won some money was checking the recent income of the palace industry. It seemed that his rebellious son liked to make money. Making money was really happy. The previous emperor was not rich by relying on the royal manor and some things sent by the tribute.

However, in the past few months, I have made a lot of money. Recently, the emperor has been thinking about whether to build a new palace. This imperial city is a bit broken, such as going to a new place near Longshouyuan to build a new one.

"There is no profit for mahjong!"

The emperor glanced at several stores that recently sold mahjong, and the profit was only two or three hundred taels a month. He couldn't help but sigh. Sure enough, the prince was right. Both sides had no money to make in price wars. Now, a mahjong can only make about one hundred coins. In the past, when it was three or four taels, he could make money...

"My son has met my father!"

Seeing that his father was cheap, Yu Zhigan didn't respond for a long time, he called out again.

"My ears are not deaf yet!" Yu Ye glanced at the prince in dissatisfaction, slowly folded the account book disguised as a memorial, and gently put it aside.

The emperor slowly raised his head and looked at the prince who was slightly angry without letting him kneel down, a little guilty.

"Did the prince know?"
