"Ding, new task, provoke the three princes, reward three months of life after completion, and cultivate to the middle stage of the internal force realm!"

When the system voice fell, Chen Xiao was stunned.

Provoking the Three Princes?

Is this thing still provocative?

Once the third prince comes back, he can't bring a knife to trouble Chen Xiao as soon as possible?

Moreover, the anger of the third prince towards Chen Xiao must be very great.

Provoke him again...... Isn't this a bit of a death-seeking meaning?

Chen Xiao licked his lips, to be honest, a little empty.

But after thinking about it, even if he didn't provoke the three princes, the three princes would definitely make trouble for themselves......

"Then I'm afraid of a hammer, he'll make trouble for me anyway, so what's the provocation?"

Thinking of this, Chen Xiao smiled, this task seems difficult, in fact, it's just like that!

So, Chen Xiao didn't care too much about it.

In Guozijian, Chen Xiao is really leisurely.

There are seven schools in Guozijian: Guozixue, Taixue, Guangwenguan, Simenguan, Law, Calligraphy, and Arithmetic.

Each of these seven schools has a Ph.D. and a teaching assistant who is responsible for teaching students.

The level of the seven schools is different, and the teaching objects are also different.

For example, Guozixue, there are five doctors, who are still in the fifth grade, and are responsible for teaching the children and grandchildren of the third-grade officials of the imperial court, as well as the children and grandchildren of the Guogong, and the great-grandchildren from the second rank and above.

Taixue has six doctors, who are the officials of the sixth grade, and the descendants of the officials above the fifth grade, as well as the descendants of the county princes, and the great-grandchildren of the third grade.

By analogy, basically, the seven schools are the children and grandchildren of the ministers and officials who teach.

As for the children and grandchildren of the royal family, the princes and younger brothers, they took classes in the palace school.

Chen Xiao was sitting on a chair at the moment, looking at the list of some students in Guozijian, and couldn't help but smack his lips:

"Amazing, this country is basically including the descendants of all the officials in this imperial capital."

Thinking of this, he realized that he, is it equivalent to saying that he has already controlled most of the officials of the Dragon Kingdom in the future?

Moreover, if you want to fight for power and profit, wouldn't it be tantamount to eating them if you are now teaching the children of all the officials in the court under your hands?

After all, that official, doesn't want his son to be better in the country?

In other words, if an official is not long-sighted and offends himself in the court, then he can return to the country to clean up your son, and ask if you are afraid?

Chen Xiao smiled, this is really a huge resource!

On this day, time flies.

After the ya, Chen Xiao swaggered and went to the outside of the Guozi Prison.

Along the way, the descendants of the ministers I met all bowed respectfully to Chen Xiao!

Chen Xiao feels very enjoyable, everyone is young, they are students, and he is the principal, which is so cool!

Back at the most hated restaurant, the fat man gave Chen Xiao a stack of silver tickets.

Chen Xiao glanced at it, and it was 300,000 taels of silver.

"Damn, where did you come from?" Chen Xiao was stunned.

The fat man said: "The profits of the five restaurants, and the money of the salt industry." ”

Chen Xiao didn't expect that in a few months, the restaurant would make so much money?

Holding the silver ticket in his hand, Chen Xiao felt beautiful in his heart, this money is a lot, and in the Dragon Kingdom, he can be regarded as a rich person.

So he took out ten thousand taels of silver, and gave it to the fat man, saying,

"Help me find someone and decorate the Chen Mansion for me."

"Chen Mansion?" The fat man wondered.

Chen Xiao said: "It's the Zhang County man's house, isn't it mine, I haven't lived in it, you let someone help me decorate it, and then invite some maids!" ”

"You're going to live? Is it not good to live in this restaurant? The fat man said.

"Don't worry if I can't live, I'm an official after all, and from the fourth rank of the official, I don't even have a mansion, like what?" Chen Xiao said.

When the fat man heard this, he took the silver ticket and turned to leave.

In the backyard, Qi Mo was raising pigs, and Bai Qingqing was watching from the side.

Seeing Chen Xiao coming, she hurriedly came over to thank Chen Xiao.

Because Chen Xiao helped her find the murderer, Zhao Kuo, the former priest of Guozijian, has been sentenced to death.

"What are your plans for the future?" Chen Xiao asked Bai Qingqing.

Bai Qingqing shook her head in confusion: "I don't know either!" ”

Chen Xiao was silent for a moment and said, "Your grandfather asked me to take care of you, or you will stay in this restaurant?" ”

"Well, I've already sold the White Mansion......" Bai Qingqing lowered her head.

Chen Xiao was speechless, it seemed that he had already made a plan.

Of course, he didn't say anything, just smiled and nodded.

After having dinner together, several people sat in the backyard to cool off.

Summer hasn't passed yet, and it's still hot.

"It's better to play in winter and play with snow and ice!" Qi Mo spoke.

Bai Qingqing also said: "You can also play ice in summer, but that has to be the palace." However, there may be no ice in the palace either, after all, it has been hot for so long. ”

The two women chatted very energetically, but for Chen Xiao, a modern person, listening to their conversation, it was really uncomfortable.

Ice? In modern times, it's a lot of things that people eat in the summer, ice cream, popsicles...... Iced Drink ......

But in this ancient world, eating ice in the summer? Even the emperor doesn't have it if he wants to eat.

Especially the ice of the ice vault is melted, eat a hammer......

Chen Xiao licked his lips and sighed.

Just when he was upset, something suddenly came to mind.

Saltpeter ice!

I believe that many people know this physics knowledge, but it is estimated that there are few who really practice it.

The principle is very simple, that is, to find saltpeter, it is best to make powder, pour it into water, you can quickly dissipate the heat in the water, reduce the water temperature to zero, form ice crystals, so as to achieve the effect of freezing.

This trick, in fact, in the dormitory when he was studying, Chen Xiao and a few buddies in the dormitory thought about doing this.

Because there was no air conditioning or refrigerator in the school dormitory, they were sometimes very hot, so a few guys discussed buying saltpeter to make ice in the dormitory.

It's just that I found out that saltpeter is actually not cheap, and the money to buy saltpeter, is it not good to buy popsicles?

So there was no practice at that time.

However, at this moment, Chen Xiao wants to practice!

So, he got up from his chair and went out to find a guy from a restaurant, and asked him to go to a nearby Taoist temple and ask a Taoist priest to buy some saltpeter.

Because of this world, the role of saltpeter is not generally recognized, after all, in ancient China, saltpeter was also found to be able to make gunpowder, so it was vigorously mined.

And why was it found that it could make gunpowder?

This is related to Taoist priests, because Taoist priests like alchemy, and saltpeter, lime, cinnabar, charcoal, sulfur, etc. all like to get together to refine medicine.

In ancient China, there was a Taoist priest who practiced and refined, and after the saltpeter was in the right proportion with charcoal and sulfur, it exploded......

Therefore, Chen Xiao asked the guy to go to the Taoist temple to find the Taoist priest to ask for saltpeter, the Taoist priest loves alchemy, and there is this thing.

Sure enough, he didn't disappoint, and when the guy came back, he pushed a cart of saltpeter.

Chen Xiao was very happy, and quickly asked people to find two wooden barrels, large and small, and after filling each with water, the small wooden barrel enlarged the water in the wooden barrel and began to make ice.
