After Qin Jue said goodbye to everyone, he began to call the system.

"System, I want to buy salt!"

Qin Jue went straight to the point, since there is a salt mine, if you don't sell salt, then this tax will be paid in vain.

"Not for sale!"

The system is also a straightforward character, and directly vetoed Qin Jue.

"Isn't salt to eat? Why not sell? ”

Qin Jue was not convinced, and directly retorted.

"Oh? Is salt edible? I'll give you a pound of salt, and you can eat it all in a big gulp, then I'll treat it as if it was eaten, and you can buy it. ”

The system replied directly.

“……”

Qin Jue stopped talking directly, a pound of salt? Eat it straight?

Don't talk about a pound of this, even if it's a bite or two, you won't be killed after eating.

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

Of course, Qin Jue was not convinced, and said directly: "You can't change the concept secretly!" ”

"Okay, since you want to buy salt, then answer me three questions, then I will sell you salt, of course, except for salt, other things, as long as you can answer my three questions, I will give you the right to buy that thing, how about it?"

The system took a slight compromise and said to Qin Jue.

"Just ask!"

Qin Jue also felt that this deal was very cost-effective, and it was not too cost-effective to exchange three questions for the purchase authority of one thing.

"What is the chemical name of table salt?"

The first question of the system was asked.

Qin Jue replied without thinking: "Sodium chloride!" ”

This question is a score question, it's very simple, but it's also a person who has attended nine-year compulsory education, and has mixed high school and college for a few years, this common sense is still understood.

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

The second problem of the system can be regarded as relatively biased, and it is impossible to know this kind of problem without reading the data.

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

He had seen this question before, and it seemed to be forwarded by a forwarding maniac in the group chat, and he just clicked in and took a look, but he wasn't sure about the correctness of this data.

"Name the mass of one mole of sodium chloride, please."

The third question, as soon as it came out, Qin Jue was stupid.

Who the hell does this remember?

I used to think I had learned it, but now I don't know it.

But this question still needs to be answered.

Qin Yu directly began to silently recite the periodic table.

Sodium ranked eleventh and chlorine was seventeenth.

It adds up to twenty-eight.

Doubling is fifty-six.

However, this relative atomic mass is a little more than double the ranking.

That is, at least fifty-eight, but it may also be a little bigger, and fifty-nine is also possible.

Qin Yu relied on the only memory in his mind to analyze and reason.

Fifty-eight and fifty-nine, although there is a difference of one, but the answer of the system is obviously only one.

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

“……”

After hearing this answer, the system closed itself directly, he didn't expect Qin Jue to be able to say this number.

This is a question he carefully planned, the first two questions are not very difficult, but the third question is really difficult, for people who do not involve the knowledge of chemistry after school, they can't guess this answer.

He didn't expect that Qin Jue would be able to guess.

The system didn't reply for a long time, and Qin Jue suddenly asked, "How is it?" My answer is okay. ”

"I didn't expect you to be able to 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: "When it comes to doing it, how much salt do you want to buy, say it." ”

Hearing this, Qin Jue was relieved.

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

Glancing at the price of salt in the system, two cents a catty, this price is very low, he has already understood the price of salt in this era before, the price is close to two hundred wen a catty.

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

If he sells this kind of salt, if it is sold for 300 wen a catty, many people will buy it.

I found a guest room in the house, and directly asked people to vacate this guest room and make it into a warehouse.

Five tons of salt were then exchanged directly from the system and placed in this warehouse.

………………

Sukoku Mansion.

At this time, Cheng Chumo had just returned home and was about to catch up on sleep.

Cheng Chumo, who hadn't slept for a day and a night, was so tired at this time that he wanted to make up for a good night's sleep.

"You scumbag! Stop for Lao Tzu! ”

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

Cheng Yanjin just looked at Cheng Chumo quietly, and there was no trace of emotion on his face.

"Why are you hitting me? I didn't get into trouble! ”

Cheng Chumo really can't think of where he is in trouble again, there is no reason at all.

"I didn't return overnight yesterday, and today there is news from Pingkangfang that you owe five hangs!"

Cheng Yanjin walked towards Cheng Chumo as he spoke, and said viciously: "What are the family rules of our Cheng family?" Staying overnight at a fireworks venue? Is it because your wings are stiff, or can't you lift the whip? ”

"No, I didn't!"

Cheng Chumo shouted directly: "When I was inspecting the camp yesterday, I found a master in the world, and I talked with him for a long time last night, and I forgot the time for a while. ”

"A master of the world? Talking to you? Fart! ”

Cheng Yanjin was directly angry, he didn't believe Cheng Chumo's words at all.

The so-called knowing son Mo Ruo's father, this kind of nonsense, Cheng Yanjin didn't believe it at all.

Cheng Chumo has a few catties and taels, Cheng Biting Jin is very clear, and he talks freely with masters outside the world?

How can people have that idle time to talk nonsense with him?

You can't tell a lie!

Cheng Biting Jin lifted the whip and walked towards Cheng Chumo.

walked to Cheng Chumo's side, directly knocked him down at once, and then tied him up with a rope and hung it on a pillar in the courtyard tailored for Cheng Chumo.

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

"Smack!"

Cheng Biting Jin directly whipped Cheng Chumo's body.

"I'll let you lie!"

"Smack!"

Another whip.

"A master of the world?"

"Smack!"

"Talk?"

"Smack!"

……

After a severe beating, Cheng Chumo was powerless to resist, and could only silently bear Cheng Bitingjin's beating.

This level of beating occurs almost once every three to five days, and Cheng Chumo has long been used to it.

At this time, he was very sleepy, and after Cheng Yanjin whipped a few times, he hung there and fell asleep.

"You old killer! Your son was killed by you! ”

At this time, a woman who looked to be in her twenties ran over quickly, looking at Cheng Chumo, who was motionless, scratching and scratching Cheng Yanjin.

"No way, I've been controlling the strength, and this bit of strength won't be able to pull him to death."

Cheng Yanjin walked to Cheng Chumo's side and took a look.

And then furious!

!

I fell asleep!

threw away the whip, and directly beckoned a pair of old fists towards Cheng Chumo's body.
