When Guan Lishi saw Li Chengqian coming out of Taiji Palace, he was like a spring breeze. Feel a little surprised, what's going on? Could it be that the tea shop has taken it back?

I was about to say hello, but I heard Li Chengqian say: "Guan Lishi, prepare the car, I want to go to the nitrate mining area in the east of the city." ”

Without further ado, this time he had to move fast, and he had his own ideas about the nitrate.

"His Royal Highness the Crown Prince, this ......"

Why to go to the mining area, he is scratching his head.

"Go quickly, and bring a basin of water by the way!"

"Yes!"

Although Guan Lishi wanted to know why he did this, he didn't dare to disobey seeing that Li Chengqian was so anxious, and the two of them went to the East Palace at this time.

After a while, Li Chengqian didn't even have time to eat lunch, so he went directly to the mining area in the east of the city.

They traveled all the way and soon reached their destination.

It's a barren place, and it looks like it hasn't been mined for a long time.

"Your Royal Highness the Prince, we have arrived."

Li Chengqian got out of the carriage and said, "You guys are guarding outside, Guan Lishi, carry the water, and go inside with me." ”

"Yes......"

Guan Lux followed in with some trepidation.

The temperature inside the mine is much cooler than the outside, so it's also very shady, but the environment doesn't seem to be very good.

After Li Chengqian walked inside.

"Put the water down, you go and fetch me a piece of saltpeter!"

Guan Lux did so, and forcefully took a stone from the wall.

Li Chengqian took it and threw the saltpeter directly into the copper basin.

With a plop, saltpeter plunged into the water.

A sneering sound followed.

Then, a burst of white water rose from the basin, which seemed to be reacting to something.

This frightened Guan Lux, his pupils gradually dilated, and at the same time, his body trembled a little, apparently this reaction startled him.

"Be careful......

The next moment, with an instinctive reaction, Guan Lux shouted.

Then something even more strange happened, only to see that the water in this basin instantly turned into ice cubes, and it also exuded a hint of coolness.

"Well, sure enough, it's nitrate."

He came here to verify his idea, and if he could, he would be comfortable in the days to come, and he would not have to suffer from the heat.

"Too... His Royal Highness the Crown Prince... This ......"

Guan Lux was a little incoherent.

Li Chengqian didn't think so, isn't it just a simple chemical knowledge of saltpeter dissolving in water to absorb a lot of heat, reducing the temperature of the water and finally freezing, and then freezing, as for being so shocked?

But think about it, now is the Tang Dynasty, or a backward feudal era, where do you understand this principle.

He was understandably shocked.

"You go and try the water in this basin."

Guan Lishi walked over tremblingly and stretched out a touch.

"It's Ice ......"

"That's right! It's ice. ”

"His Royal Highness the Crown Prince, this ......"

Li Chengqian interrupted Guan Lishi's words, there are some things, do more and say less.

He said: "In the future, some saltpeter will be transported to my East Palace every day, this thing will turn ice when put in the water, as for the principle, don't ask, I can't explain it clearly." ”

As long as the result is fine, as for the process, he doesn't have the tongue to explain too much, and Guan Lishi doesn't dare to ask too much, even if he has a thousand questions in his heart, he can only swallow it.

He only felt that the prince had become a little different after falling into the water, and he was also present at the time.

"Yes, yes...... I'll let people do it every day from now on. ”

Li Chengqian thought more, he wanted to make the ice bigger, but no matter what he did, he would be monitored by Li Shimin, he couldn't help but stare at Guan Lishi, and Guan Lishi was a little dazed.

"Pipe Lux! Your Majesty knows about our sales, didn't you say it! ”

For Li Chengqian's sudden attack, Guan Lishi was so frightened that he knelt down. This is a big deal, and the master in front of him is not an existence that he can provoke.

"His Royal Highness the Prince! How dare the old slave do this? I'm loyal to you......"

And he almost burst into tears.

Li Chengqian believed him, because he said that the eyes of the panicked would look to the right, and they would not dare to look into his eyes. Guan Lux is the opposite, listening to this, it seems that he is loyal.

"Guan Lishi, I will treat you as a confidant, and the benefits will not be lost to you, but if you dare to betray me, you will know the end!"

The ruthlessness shown by Li Chengqian just now made Guan Lishi shudder.

"The old slave's loyalty can be seen in the world, even if I give me ten, a hundred dares, I don't dare to betray His Royal Highness the Prince!"

"I know, just now I just scared you and let you know the seriousness of the problem, this time I have to do a big thing, I can't let Your Majesty know, otherwise all the money I earned will fall into Your Majesty's pocket, and my hard work will be in vain, do you understand? My East Palace is good, and your benefits are indispensable, if it is not good, life is still tight. ”

"The old slave understands!"

What Li Chengqian said was that he was being monitored, and Guan Lishi was also shrewd, he said: "Maybe it is related to the guards of His Royal Highness the Prince, you know, we only brought some guards with us that day, maybe they we." ”

It's not impossible, there are a lot of people, so Li Chengqian said: "You choose a few henchmen for me, and replace the guards in the East Palace who can get close to my bedroom!" Let them do other things! This thing must be done well, not to be underestimated, because it involves our business problems in the future. ”

As long as you change all the guards who can get close to you, then your next actions will be safer.

To play with Li Shimin, you have to play like this, otherwise your efforts will be all pitted by Li Shimin, and your efforts will be in vain.

"Of course, the old slave has a few candidates to replace the original guards."

"That's great! By the way, you've recently recruited some businessmen for me, and I want someone with high ability. ”

Li Chengqian has already begun to plan the next move, and this time he can't let Li Shimin grasp the handle no matter what.

"Your Royal Highness the Prince, I know that there is a suitable person!"

Guan Lishi suddenly thought of a person.

"Oh? Who is it? ”

"Zou Fengchi of Huaide Fang!"

Zou Fengchi was the richest man in the Tang Dynasty, and if he could recruit for his own use, it would definitely complement each other.

"What's so good about him?"

"It only took two years for this person to go from nothing to a fortune."

Li Chengqian thought to himself, this person can indeed be a good partner.

"Okay, summon him to the East Palace immediately, I want to see him! No! Wait a minute! ”

"His Royal Highness the Crown Prince?"

"As long as you and I go, this matter still has to be done in secret."

Li Chengqian thought about it later, and felt that it was better to keep a low profile, so he decided to do so.

"Yes!"

Li Chengqian didn't say it, Guan Lishi should have guessed that what he wants to do now will be another big thing, something bigger than tea. He didn't know how Li Chengqian could have so many ideas.
