Datang: It's a showdown, my son-in-law is going to rebel!

Chapter 20
After Cheng Chumo heard this, he was completely speechless. He didn't like reading, and he couldn't stand military books. He knew how to arrange troops with a hammer.

"You are the assistant teacher of Guozi, so do you know how to form troops?"

Cheng Chumo was also unconvinced, and Fang Qi said, "I don't know how to form troops, but will you?"

"I don't know how, so I continue to study in the Imperial College. If I have time, I can study some military books."

Fang Qi said to Cheng Chumo: "Now I'm in the Imperial College, learning something, maybe I can use it when studying military art, maybe I can use it on the battlefield in the future, who knows?
Enrich yourself now, and when you encounter problems in the future, you will be able to try your best to solve this problem.

Now when you encounter problems, you shrink back, and when you encounter problems in the future, you will still shrink back and keep shrinking. When you can’t shrink back, what can you do?
With a cavity of blood, go to the battlefield to give away the head? "

"Hmph! My father can dominate on the battlefield, can't I?"

Cheng Chumo said to Fang Qi: "My father has never been to the Imperial College, and he didn't even know a few big characters back then. Couldn't he also go to the battlefield? Why can't I?"

"Then can you beat your father?"

Fang Qi looked at Cheng Chumo, looked at the other people with a smile on his face and asked, "What about you? Can you beat your father?"

This is a question from the soul.

Can't beat it!

If you can beat it well, do you still need to study hard here?
If they could beat Dad, they would have joined the army long ago and started training. Why should they learn these things here?

Cheng Chumo looked at Fang Qi and said with a snort: "You're cruel! Just tell me if you don't want to help. Why are you teasing me like this?"

"Sorry, I didn't play tricks on you."

Fang Qi said to Cheng Chumo: "If there is a chance, I will go and talk to His Majesty about this matter, but for now, you should go back first."

Fang Qi didn't say much, these second generations are really a headache, but Fang Qi still has a way to make these guys obedient, but he didn't talk to Li Er about these things, if he didn't go through Li Er, this matter would basically come true no.

Fang Qi felt that he needed to go find Li Er.

But now he is just an assistant coach of Guozi, and he has no chance to meet Li Er at all.

This matter was delayed for the time being, Fang Qi returned to the classroom of the Mining Computing Department, looked at these people who were writing hard, and then said: "Okay, you don't need to continue, hand over the papers to me, I will Come and see."

Fang Qi put away the papers of these people and looked at the paper he had just handed out. This time the paper was actually the multiplication table, which was messed up and asked to be done by these people.

Fang Qi saw that these people hadn't finished, and immediately wanted to see how they were doing.

Soon the paper was in his hand, and Fang Qi roughly flipped it a few times.

"Well, it's pretty good. Although some write fast and some write slowly, generally speaking, your brains are fine. Today, I will teach you how to use the four arithmetic operations!"

Fang Qi started today's teaching, and when he finished speaking, everyone fell into a state of confusion.

What the hell!

so simple?

This thing is much easier to use than calculating chips!

As long as you make a vertical formula, you can get the answer quickly, this is simply too much!

It’s just that this seems a bit useless!

"Professor, although this vertical method is simple, it consumes paper, and the value of paper is very expensive. Ordinary people may not be able to afford such a high cost."

Li Tai said to Fang Qi: "Since this is the case, not many people will choose to use this method."

"Paper is expensive?"

Fang Qi suddenly caught the key point from Li Tai's words.

"Teacher, don't you know?"

Seeing Fang Qi's expression, Li Tai was stunned.

In this world, is there anyone who doesn't know that paper is very expensive?
"It's interesting."

Fang Qi touched his nose.

If paper is so expensive, if I make paper, will it be a problem?

No, this matter needs to be carefully planned. Changsun Wuji gave Lao Tzu five shops, two in West Market, one selling salted fish and the other selling salted meat.Of the three in Dongshi, one will sell paper, and the remaining two will figure out how to do it when the time comes.

Fang Qi actually had a plan in mind, since Changsun Wuji gave five shops, it is natural that the value for money should be excellent.

The West Market is a mixed bag, where you can buy salted fish and meat. The East Market is a noble place that ordinary people can't enter, so it naturally needs to be a little taller. Paper can just meet this requirement.

After Fang Qi figured it out, he immediately came up with a plan to make paper. In this Tiangong Kaiwu, there is papermaking technology and movable type printing.

Can we open a bookstore in Dongshi?

No, I'm going to do a market research to see how to make money.

Fang Qi only has a few bucks of money on him now. He spent a lot of money on those things before. Although the salted fish is ready now, he hasn't started selling it yet. It's not possible without money.

Now that we have returned to ancient times, we must have money and power, otherwise we will not have the fun we deserve.

In ancient times, if you wanted to enjoy the blessings of everyone, there was no need to learn time management. What a good era, so you naturally had to work hard.

"This vertical posture has taught you. Next, you should learn this thing carefully. If you don't have paper, you can write and draw on the ground. You can even use sand to do these things. After you finish the calculation, smooth the sand and you can continue to use it. gone."

Fang Qi made a haha, and then left directly.

Several students looked at the back of Fang Qi leaving, and after thinking about what Fang Qi said at the end, they suddenly felt a little clueless, there is no paper, you can use sand!

This thing is worthless, and it can be used all the time, yes!

After Fang Qi left Guozijian, he didn't start doing regular market research, but went to the East Palace. After such a long time, he didn't know if Li Chengqian would be able to get up.

It's time to go back and have a look. Although he has now become an assistant teacher of the Imperial Academy, he is still a student of the prince. The assistant instructor of the Imperial Academy is only a part-time job, and his job should not be forgotten.

When he arrived at the East Palace, Li Chengqian was kneeling in front of Li Shimin.

Looking at Li Er's expression, he knew that Li Chengqian had made a mistake again.

Seeing this, Fang Qi suddenly felt bad.

What's the matter with Li Chengqian?
This injury hasn't healed yet, why did it provoke Li Er again?

"Fang Qi?"

Li Shimin heard the movement, turned around and saw Fang Qi: "You are teaching at the Imperial College, so you are leaving your post right now?"

"..."

Fang Qi's whole body is not well.

What the hell!

This shit, Li Er was in a bad mood, so he bumped into him directly, this shit is going to end!
