This student really aroused Wang Xiaotong's curiosity.

Wang Xiaotong decided to come up with a few difficult questions to test the prince to see how far he had studied arithmetic.

And Li Su looked at Wang Xiaotong's expression, and guessed what he wanted to do.

Li Yucai didn't want to be bored with those childish topics.

Therefore, before Wang Xiaotong could open his mouth, Li Su decided to strike first.

Li Su couldn't help asking: "Master, when the student is studying arithmetic, he encounters a problem, I wonder if Mr. can solve the student's confusion?" ”

After hearing Li Su's words, Wang Xiaotong couldn't help but smile slightly.

This prince is very interesting.

He didn't take the test yet, but he took the test for his own gentleman.

Okay, let's let Ben see what problems he can have.

Thinking of this, Wang Xiaotong couldn't help but smile and asked: "Okay, I don't know what problems Your Highness has encountered, you might as well speak it out and listen to it, and let Master Benzi solve your doubts for you." ”

Li Su couldn't help but say: "The topic is like this, it is known that there is a team of 100 zhang long, and the herald stands at the head of the team. At this time, the procession moved at a constant pace, and the herald moved from the head of the platoon to the end of the platoon at a constant speed at the same time. ”

"When the herald got to the end of the row, he turned around and walked forward at the same pace. When the herald caught up with the leader, both sides stopped at the same time. At this time, the team walked forward a hundred feet. Ask, how far did the herald go? ”

After listening to Li Su's question, Wang Xiaotong couldn't help frowning and thinking.

Next to him, Cheng Chuliang couldn't help but whisper to Yu Chi Baoqi: "What is His Royal Highness the Sixth Prince talking about?" Why can't I understand? ”

Yu Chi Baoqi said with a dark face: "Don't speak, be careful that the master hits your board." ”

Well, well, in fact, Yu Chi Baoqi didn't understand what he was talking about.

On the other side, Fang Yiai asked Li Tai the same question.

However, Li Tai was also thinking hard about this topic, and he didn't care about his love at all.

Li Tai is both civil and military, and has always been deeply loved by Li Shimin, and he thinks very highly of himself.

He didn't believe that an arithmetic problem from his former stupid sixth brother could be difficult for him.

But this question is really too difficult.

He can understand the question, and he also feels that there will be a definite answer to this question.

But there were too few clues given, let alone solving the problem, and now he didn't even have an idea of how to solve the problem.

The more this is the case, the more Li Tai thinks hard, and his brows are wrinkled into a Sichuan character.

And their arithmetic gentleman, Wang Xiaotong, was immersed in this topic. Before I knew it, I had already stepped onto the podium and began to draw images with a pen and sort out the steps to solve the problem.

After a while, there was not enough manuscript paper, so Wang Xiaotong walked out directly with the manuscript paper that had been checked.

Seeing Wang Xiaotong leaving, Li Su directly packed up his textbooks and prepared to get out of class.

Cheng Chuliang pulled Li Su and asked, "Your Highness, why are you going?" If you can't see you when you come back after solving the problem, you will wait for the board tomorrow. ”

Li Su smiled and said, "Don't worry, this problem can't be solved by the master today." ”

Cheng Chumo asked suspiciously: "That's the master, are you sure the master can't solve it today?" ”

"Of course."

As he spoke, Li Su had already packed up his textbooks and walked out with his feet raised.

Cheng Chumo gritted his teeth and followed Li Su out.

Anyway, even if the master comes back, he won't just skip class alone, he will be punished by everyone, anyway, there is a Royal Highness to accompany him.

Li Su is really sure that the master can't solve the answer today.

This problem is a well-known problem.

Even in the next generation, it is a small problem.

At least a binary quadratic equation or a ternary quadratic equation can be solved.

It can be said that in the entire Datang, there are absolutely only a handful of people who can solve this problem.

And even if they can solve it, they must do it with water grinding skills, and it is absolutely impossible to solve it in a very short time.

Before the two of them walked out of the school, Yu Chi Baoqi and Qin Huaiyu and several others also chased them out.

Cheng Huailiang couldn't help but say to Li Su: "Your Highness, what about the first side in the world?" Go get me five packs. ”

Huo, this guy hasn't forgotten about instant noodles.

Li Su said to Cheng Huailiang: "You wait here for a while, and I'll go get it for you." ”

found a place where no one was, and Cheng Huailiang directly turned on the system.

However, when he saw the price of instant noodles, Li Su was directly dumbfounded.

Because he was shocked to find that the price of instant noodles has actually increased to 0.5.

This is already the same as the price he sold, and he, a middleman, doesn't even make a penny.

Li Su couldn't help but ask angrily: "System, you give it to me, why has the price of instant noodles become so expensive all of a sudden?" 500 wen a pack, why don't you grab it? ”

Then, Li Su listened to the system and replied mechanically: "Please note that if the host uses the goods in the mall to make a profit, the mall will raise the price simultaneously." The system prompts that the final interpretation right belongs to the system. ”

it, is it so tsundere?

What do you mean, hey?

But soon, Li Su figured out the purpose of the system.

It seems that the meaning of the system is that you can't make money directly by selling the goods in the system.

The system will only play an auxiliary role, and if you want to make money, you still have to rely on yourself.

With such a tsundere system, there is really no one.

It seems that his dream of making a fortune with instant noodles has been shattered.

Li Su suddenly thought of a question, and hurriedly asked: "System system, the price of water-based polyester paint, won't it rise?" ”

The system prompts: "As long as the host does not sell directly, the price will always remain the same." ”

Hearing the system's explanation, Li Su couldn't help but nodded.

Sure enough, as I expected, the system can only play an auxiliary role, and cannot rely on the system to make money directly.

Well, I guess when I sold instant noodles for the first time, it was because I hadn't paid off the arrears of the system, which was an exception.

After paying off the arrears, the system immediately raised the price.

In this case, then for the time being, I can only rely on water-based polyester paint to make money.

Of course, it is not directly selling water-based polyester paint, Li Su wants to sell Taishi chairs.

This high-gloss lacquer brushed with paint, the craftsmanship of the Tang Dynasty will definitely not achieve this effect.

In this case, the business of this Taishi chair can take the high-end route.

Thinking of this, Li Su took the instant noodles and handed them to Cheng Huailiang and others.

Then he called a few people together and quietly asked, "Hey, there is a profitable business now, do you want to do it?" ”

As soon as he heard this, Cheng Huailiang immediately became interested, and hurriedly said with bright eyes: "I think about it, I think about it so much, Your Highness, you quickly say, what kind of business is it?" ”
