After Qin Xi bid farewell to everyone, he began to call on the system.

"System, I want to buy salt!"

Qin Yu went straight to the point. Since there was a salt mine, if you didn't sell salt, the tax would be paid in vain.

“Not selling!”

The system is also straightforward and directly rejected Qin Yu.

"Isn't salt eaten? Why not sell it?"

Qin Yu was dissatisfied and directly refuted.

"Oh? Is salt eaten? I'll give you a pound of salt and you will eat it all in big mouthfuls. Then I'll treat it as eating and you can buy it."

The system directly retorted.

“…”

Qin Xi stopped talking, just eat a pound of salt?

This is a bite, not to mention one pound, even if it is one or two bites, you will be choked to death after eating it.

"This salt is something that people must eat, but who will eat so much?"

Of course, Qin Xi was dissatisfied and said directly: "You can't change your concept!"

"Okay, since you want to buy salt, then answer my three questions, then I will sell the salt to you. Of course, except for salt, you can answer my three questions, and I will give you the right to buy that thing. How about it?"

The system took a slightly compromise and said to Qin Yu.

"You ask!"

Qin Yu also felt that the deal was very cost-effective. It was simply too cost-effective to change the purchase permission of another thing in three questions.

"What is the chemical name of salt?"

The first question of the system was asked.

Qin Xi replied without hesitation: "Sodium chloride!"

This question is a free score question, which is very simple. After all, it is a person who has attended nine-year compulsory education and has been in high school and college for several years. I still understand this common sense.

"What is the approximate amount of salt a normal person consumes in a day?"

The second problem of the system can be considered relatively biased. It is impossible to know this problem without reading the information.

The moment Qin Yu heard this question, he was stunned for a moment, and then said with some uncertainty: "3 grams?"

He had seen this question before. At that time, it seemed that it was a reposted by a reposted maniac in a group chat. He just clicked in and looked at it, but he was not sure about the correctness of this data.

"Please tell me the mass of a mole of sodium chloride."

The third question, as soon as it arose, Qin Shi was stunned.

Who remembers this?

I seemed to have learned it before, but I definitely don't know it now.

However, this question still needs to be answered.

Qin Yu began to recite the periodic table of elements silently.

Sodium ranks eleventh, and chlorine shots eleventh.

The total is twenty-eight.

Double that is fifty-six.

But this relative atomic mass is a little larger than the ranking.

That is to say, it is at least fifty-eight, but it may be bigger, fifty-nine is also possible.

Qin Xi used the only memory analysis in his mind to reason.

Although fifty-eight and fifty-nine are just one difference, the system's answer is obviously only one.

After struggling for a while, Qin Sheng gritted his teeth and replied: "Fifty-eight-five grams!"

“…”

After hearing this answer, the system became autistic. He did not expect that Qin Yu could actually say this number.

This is a question he carefully planned. The first two questions are not very difficult, but the third one is really difficult. For people who do not involve chemistry after school, they cannot guess this answer.

He didn't expect that Qin Yu could guess.

The system has not responded for a long time, and Qin Xi asked immediately: "How is it? My answer is OK."

"I didn't expect that you could answer all three questions correctly!"

The system was quite unhappy, but since he had already said it, he did not regret it and said directly: "Do what you say, how much salt you want to buy, say it."

Qin Xi felt relieved when he heard this.

Looking at the golden cake that had just been recharged, Qin Yu was still quite calm. Fang Yiai gave him a piece of golden cake before, so now he can be considered a rich man.

He glanced at the system's salt price, which cost two cents per kilogram, which is very low. He had already learned about the salt price of this era, and the price was close to two hundred cents per kilogram.

The quality of salt in this era is not as good as the salt provided by the system, and there are a lot of impurities.

If he sells a salt of his quality, many people will buy it if he sells it for 300 pounds per pound.

I found a guest room in the house and directly made a warehouse.

Then, five tons of salt were exchanged directly from the system and placed in this warehouse.

……………………

Su Guo Duke's Mansion.

Cheng Chumo had just returned home at this time and was about to take a break.

Cheng Chumo, who had not been sleeping for a day and a night, was so tired that he wanted to have a good night's sleep.

"You prodigal son! Stop for me!"

Cheng Yaojin held a whip and a rope in his hand: "Do you do it yourself or do it?"

Cheng Yaojin looked at Cheng Chumo quietly, with no trace of emotion on his face.

"Why do you want to hit me? I didn't get into trouble!"

Cheng Chumo really couldn't imagine that he had caused trouble again, so there was no reason at all.

"I didn't return overnight last night, and today I heard from Pingkangfang that you owe five dollars!"

Cheng Yaojin said as he walked towards Cheng Chumo and said viciously: "What are the rules of our Cheng family? Staying at night in a fireworks place? Is your wings hard, or is it that I can't lift the whip?"

"I'm not wrong!"

Cheng Chumo called out directly: "When I was patrolling the private camp yesterday, I found a paradise. I talked with him for a long time last night and forgot the time for a while."

"A paradise? Talk to you? Fart!"

Cheng Yaojin was furious directly, and he didn't believe Cheng Chumo's words at all.

Cheng Yaojin doesn't believe the so-called "no one knows his son" than his father.

How much does Cheng Chumo have? Cheng Yaojin knows very well and talks with a foreigner?

How can they have the time to talk nonsense with him?

I won't even tell a lie!

Cheng Yaojin lifted the whip and walked towards Cheng Chumo.

He walked to Cheng Chumo's side, knocked him down immediately, tied him up with a rope, and hung it on a pillar tailored for Cheng Chumo in the yard.

"I'll let you stay overnight in Pingkangfang!"

"Bang!"

Cheng Yaojin directly whipped Cheng Chumo with a whip.

"I'll let you lie!"

"Bang!"

Another whip.

"A paradise?"

"Bang!"

"Talk?"

"Bang!"

...

After a burst of beating, Cheng Chumo was unable to resist and could only bear Cheng Yaojin's beating silently.

This level of venomous beating happened almost once every three or five days, and Cheng Chumo had long been used to it.

He was very sleepy at this time. After Cheng Yaojin whipped a few whips, he hung there and fell asleep.

"You old killer! Your son was beaten to death by you!"

At this time, a woman who looked over 20 ran over quickly and looked at Cheng Chumo who was motionless and scratched Cheng Yaojin.

"I can't. I've been controlling the force all the time. This force will not kill him."

Cheng Yaojin walked to Cheng Chumo and took a look.

Then he was furious!

grass!

He actually fell asleep!

He threw away the whip and directly greeted Cheng Chumo with his old fists.
