"Teacher." He Yong stood up immediately when he saw Li Feng on the stairs.

The others also stood up instantly. They all looked at Li Feng with admiration, then respectfully raised their hands and said, "See Lan Tianhou."

Li Feng nodded and said: "He Yong has told you, I accepted him as a disciple and planned to explain mathematics to him. For this reason, I plan to teach more people.

You are all like-minded friends of He Yong, so you will become my priority.

Now you can choose to stay, or you can choose to leave and take part in this year's imperial examination."

Someone stood up and said with cupped hands: "Marquis Lantian, student Wang Li, is willing to stay and listen to your class.

But students are curious, why did Marquis Lantian say we can take part in the scientific examination?"

Li Feng explained: "Because His Majesty said it himself yesterday, people of the Tang Dynasty, even the sons of merchants, can participate in the imperial examination.

This news will be published in the newspaper today. If you don’t believe it, just buy a newspaper and take a look. Well, now I’ll give you a choice, stay or take the imperial examination.”

Li Feng asked again.,

"The student is willing to stay." Wang Li said again.

"Students stay too."

"Students are also willing to stay."

"Students want to take the imperial examination."

"Students also want to take part in the imperial examination."

"..."

At one time, ten people wanted to take part in the imperial examination, and the remaining twenty-five people, including He Yong, were willing to stay.

He Yong looked at the ten people who had betrayed everyone and shouted angrily: "Do you want to be traitors? Have you forgotten our oath?"

"Shut up." Li Feng immediately scolded, "He Yong, everyone has their own ambitions. Since they are going to take part in the scientific examination, let them take part.

Let me tell you, making inventions and conducting research requires single-minded concentration to succeed. What's the use of reluctantly keeping them now? They may have nothing, but you have an extra burden."

"But……"

"No but, you have to listen to what I say. If you don't want to listen, don't think of me as your mentor." Li Feng said solemnly.

He Yong didn't say anything, but glared at the ten people angrily.

As for the other twenty-four teenagers, they were also very angry, feeling that they had been betrayed, and regarded each other as traitors.

Li Feng walked downstairs and said: "Those who still want to take the scientific examination, please leave when you are full."

"Farewell."

"Farewell."

"..."

Ten teenagers don't want to stay here. Being looked at like that makes them feel like traitors. It's very uncomfortable. They might as well leave as soon as possible.

After Li Feng watched the ten people leaving in embarrassment, he said: "Come here, bring the books."

Immediately, a waiter brought up math books and exercise books, placed them next to Li Feng, and then left.

Li Feng pointed to the books and said: "These are math books and some exercises that I had people print and make overnight. He Yong, please organize them and give each person a set."

"Yes." He Yong immediately arranged for two people to distribute the books and materials with him.

Li Feng saw that they each had a set of mathematics materials and said: "For the next month, I will teach you mathematics every day. After a month, I will return to Lantian County. If you want to learn, you can come to Lantian County. I will teach He Yongshi,

Let me teach you by the way."

"We will definitely come." Everyone replied at the same time.

Li Feng nodded with satisfaction, looked at He Yong, and said, "Is the classroom ready?"

"Except for tables and chairs, everything is ready." He Yong replied.

"lead the way."

"yes."

Under the leadership of He Yong, everyone came to a large house. The house was very large. According to He Yong, there were more than 60 rooms in total. It was the big house of his He family.

Li Feng was surprised that such a mansion could be sold for at least 100,000 guan in Chang'an. If it was in a prosperous area, it would cost 180,000 guan instead of 200,000 guan.

Li Feng said: "From now on, this is where you will listen to classes, and it will also be where you teach."

"Teacher, what do you mean?" He Yong heard.

Li Feng said: "After you have learned my skills, I want you to teach others my skills too.

I have two purposes in doing this. The first is to carry forward the knowledge of my mentor. The second is to make everyone recognize you.

Because you are the descendants of merchants, both the people and the government disapprove of you."

"But doesn't His Majesty still allow us to take part in the imperial examination?" Wang Li said.

Li Feng said: "It's just that Your Majesty, I and a very small number of people agree with you. That's not enough. I want all the people in the world to agree with you.

So you have to let the children in Chang'an City and surrounding areas who cannot afford to study go to school.

This big house is just right, with more than sixty rooms, each room can accommodate forty or fifty students.

There are twenty-five of you, so let’s recruit students from twenty-five rooms first. According to the number of forty students in each room, that is to say, you have to recruit one thousand students.

After the students are recruited, each of you will be responsible for a room of students, and you will be responsible for their meals and study expenses here. Are you willing?"

"Disciple is willing." He Yong was the first to agree without thinking.

Wang Li was the second to agree.

Come on, everyone nodded in agreement.

They can definitely afford the food and education expenses for forty people. Their usual meal can be worth the cost of feeding forty children.

Li Feng was very satisfied and said: "You are very good. Believe me, even if you learn my skills and cannot become an inventor, you can still become a good educator.

This is also a small compensation from me for your future. You can go back and tell your fathers about this, and if they don't agree, then forget about it."

Wang Lidao: "Marquis Lantian."

"Call me mentor. I taught you, and you are my disciples."

Wang Lidao said happily: "Yes, mentor. Please rest assured, mentor. This disciple will definitely not disappoint his mentor."

Others also excitedly raised their hands and said, "Teacher, please rest assured that this disciple will not disappoint his teacher."

He Yong didn't know whether he was happy or jealous. His father had begged the emperor for his apprenticeship, but they accepted it so easily.

Having said that, I am no longer my junior brother, so I should be happy about this.

Li Feng ignored what He Yong was thinking, but looked at Wang Li and the other group of people. He was very satisfied. He said: "Very good, today I will teach you mathematics briefly, and then do a small experiment for you to let you know the mathematics."

The magic of transformation.”

"Teacher, what is mathematics and physics?" Wang Li asked.

Others also stared at Li Feng curiously.

Li Feng had no choice but to explain what mathematics, physics and chemistry were, and then gave an introduction to the first-grade mathematics class.
