Datang: Royal Tyrant, Slaughtered Five Surnames and Seven Wang at the Beginning

　　"what?"

　　Hearing this, Li Shimin was completely shocked!

　　"The cost of such fine refined salt is only twenty dollars per tael!?"

　　Empress Changsun was also stunned.

　　It's really hard for them to understand!

　　They thought that such fine salt must be very expensive.

　　For every two pieces of refined salt, the cost reaches two or three hundred dollars, and they all believe it!

　　but now!

　　Li Chengqian told them that they only needed the cost of twenty dollars, which made them really unable to believe it!

　　Princess Changle has always lived in the deep palace.

　　She has no idea about the cost of these salt prices.

　　So she just calculated according to Li Chengqian's words,

　　"The cost of each tael is [-] yuan, and the selling price is [-] yuan, so you can earn [-] yuan per tael!"

　　For such a simple arithmetic, Chang Le had to break his fingers to calculate it.

　　Li Chengqian smiled slightly.

　　Although he meant to laugh at Chang Le, he also understood that such a level of arithmetic was normal in the early Tang Dynasty!

　　After all, in an era when there was no division table of ninety-nine,

　　Do you still want to ask how much arithmetic speed these people have?

　　"Then if you sell [-] catties every day, you can earn..." Princess Changle continued to squeeze her fingers, but it still seemed very difficult.

　　Li Chengqian replied: "I can make [-] yuan!"

　　hiss!

　　Empress Zhangsun took a deep breath!

　　Empress Zhangsun is in charge of the expenses in the palace. She understands that this [-] yuan is enough for the expenses of the palace for a day!

　　At such a low price, refined salt can still make so much money.

　　Empress Changsun can no longer describe her son, the crown prince, in words!

　　"And my salt shop can sell about seven or eight thousand kilograms of refined salt every day, so it can make about five or six million dollars."

　　Li Chengqian spoke very calmly.

　　But this number has deeply shocked Li Shimin's mind.

　　"Gao Ming, can you take your royal father to the place where you refine refined salt?"

　　Li Shimin said pleadingly.

　　In the end, even if Li Chengqian said this, Li Shimin didn't really believe it, so he wanted to see it believing.

　　"Brother Prince, Chang Le also wants to visit." The beautiful Chang Le also took the initiative to say.

　　If it was only Li Shimin's request, Li Chengqian would not necessarily pay attention.

　　But his sister has spoken, how could Li Chengqian refuse!

　　"Okay! Then I'll take you to see it."

　　"This is my first assembly line salt factory in Datang!"

　　……

　　Inside the salt mill.

　　When Li Chengqian brought Li Shimin and the others, the guys inside were in full swing!

　　"What is this doing?"

　　"Is this filtering?"

　　"Filter? What do you mean?"

　　"It means to get out the bad things in the salt mine. Anyway, you can't understand it."

　　"What is this doing?"

　　"Salt! It can improve the purity of salt!"

　　"What is purity?"

　　"It's the difference between refined salt and fine salt."

　　Li Shimin walked into the salt factory like a curious baby.

　　Whatever he saw, he felt very curious.

　　Whatever he saw, he wanted to ask.

　　Li Chengqian explained the simple and easy-to-understand things directly.

　　But for more complicated things, he can't do anything.

　　Because even if the explanation is clear, Li Shimin will not understand.

　　After all, this is a gap spanning millennia.

　　"Everyone has a division of labor, so it's really a big improvement in speed."

　　Although Li Shimin does not know the meaning of assembly line production, he also knows that doing so can greatly improve efficiency!

　　"How much refined salt can such a salt factory produce every day?"

　　Li Shimin asked again.

　　Li Chengqian was a little modest,

　　"Probably produce more than [-] catties per day!"

　　"What!?" Hearing this number, Li Shimin roared hysterically!

　　Even though there was a lot of noise in the salt pan, it still didn't cover up Li Shimin's roar!

　　"Hehe!" Cheng Chumo, who was standing aside in charge of the guard, smiled hehely.In fact, when he first learned about this terrifying output, he was also shocked!

　　But now, seeing His Majesty's face with such a shocked expression is still quite funny.

　　"My son, don't you lie to me?" Li Shimin carefully confirmed.

　　Li Chengqian and Li Shimin rolled his eyes,

　　"I'm idle, why should I lie to you?"

　　"The salt field is here, you can go and see it, the daily output is still very familiar."

　　Li Shimin really went into each workshop, observed it carefully, and then checked it again.

　　It was found that Li Chengqian had forgotten about it just now.

　　If you really want to count.

　　this salt pan.

　　The daily output per day may reach [-] catties!

　　"My God! This is refined salt, and it can actually reach a daily output of [-] jin!" Li Shimin was really scared to death by this number!

　　But after the shock, there is joy!

　　Li Shimin began to draw close to Li Chengqian, "Hey, my good prince."

　　Looking at Li Shimin's smile, Li Chengqian knew that nothing would be good.

　　"What is the father going to do?"

　　"I see this salt field, it's still very good, and as a prince, you are very busy, why don't you hand this salt field to the national treasury!" Li Shimin made no secret of it!

　　"I go!"

　　Li Chengqian was about to scold immediately.

　　This Li Shimin is really a Zhou Shimin!

　　To the treasury! ?

　　If it is really handed over to the state treasury, it will become his Li Shimin's money bag. .

Chapter 56

　　Chapter 56: Slaughtered the Langya Wang Clan!Taiyuan Wang's shock!

　　"Impossible! Absolutely impossible!" Li Chengqian quickly waved his hand!

　　Cheng Chumo also stuck out his tongue at Li Shimin and muttered, "Your Majesty is too greedy, didn't you already take the drawings of His Royal Highness the Prince's Mo Dao and Horseshoe?"

　　Cheng Lumo's words made Li Shimin very embarrassed.

　　With the blueprints of Mo Dao and horseshoes, Datang's army has ruthlessly enriched their armaments!Moreover, these drawings were all submitted by Li Chengqian on his own initiative.

　　Now I have to come to get the salt field again, which seems to be really bad.

　　But Li Shimin still kicked Cheng Chumo,

　　"Hey! You're following behind the prince now, and you're getting more courageous. Your father doesn't dare to talk to me like that here."

　　Cheng Chumo quickly begged for mercy.

　　Li Shimin said to Li Chengqian again:

　　"That's all. Let you manage this salt field first."

　　Li Chengqian was speechless.

　　This salt field was originally his own.What does it mean to be handed over to him to manage.
