Chapter 80

Xu Ziyan guessed that after LAN Yin was driven out of her home, she had to worry about her livelihood in addition to going to school.

So after school, where is she going to work?

Although he said he would pay tuition fees, LAN Yin should be driven by self-esteem and refuse to accept his own offer.

When she was rejected, Xu Ziyan felt a little lost.

But now, because of Sun Zhen's words, LAN Yin promised to help her review her lessons. Xu Ziyan even felt that she didn't hate Sun Zhen as much as before?

But even if it's not too annoying, she will study well with LAN Yin, improve her math scores and crush Sun Zhen's cheap thing!

Xu Ziyan doesn't know why. She has an inexplicable sense of trust in LAN Yin's classmates.

LAN Yin said that she could pass the monthly exam next Monday. If her math score exceeded Sun Zhen, Xu Ziyan would think she could really do it!

After a brief tit for tat between several people in the classroom, the class bell rang.

The Chinese teacher in charge of teaching in this class walked into the classroom.

The Chinese teacher in class 11 is a middle-aged man over 40 with a very old face.

In addition to being the Chinese teacher of class 11, he is also the head teacher of class 10, grade 3.

Due to years of hard work, he had white hair in his forties, his face was loose, and the corners of his eyes and mouth were wrinkled.

In last week's course, LAN Yin had listened to more than ten Chinese classes. The Chinese teacher spoke well.

However, what Lanyin noticed most was not the teaching effect of the Chinese teacher, but his illness.

Although LAN Yin has not systematically studied medicine, she only knows a little about medicine.

However, when she was developing medical machinery for some time, she had a certain understanding of the diseases within the scope of her medical machinery.

When she had her first Chinese class last Monday, she didn't find anything in her Chinese teacher.

But after a few days of observation, she was able to judge that the Chinese teacher was suffering from cancer.

Because it is the middle stage of cancer, he has no attack for the time being. He should not know it himself.

The emergence of cancer made LAN Yin realize that the medical level more than 100 years ago was that cancer was equivalent to a terminal disease!

Therefore, after the portable "operating machine", LAN Yin plans to manufacture a phototherapy machine that can cure cancer, leukemia, AIDS, hemophilia and other diseases.

The phototherapy machine is not as simple as an operating machine. Even after more than 100 years, it has not been popularized. It is only available in hospitals of a certain level.

Therefore, if you want to copy the phototherapy machine to this era, you will inevitably need money.

And a lot of money!

Some metals needed to make the interior of the phototherapy machine are not ordinary metals.

The price of some metals is even a hundred times higher than that of gold per gram!

It was also for this reason that Lan Yin first went to make the "surgical machine" instead of directly making the phototherapy machine.

In the classroom, the Chinese class has begun.

In the back of the classroom, LAN Yin, who was considering the cost of the phototherapy machine, the mobile phone in the desk drawer vibrated——

She took out her mobile phone and looked down. An account entry message appeared in front of her.

"One, ten, a hundred, a thousand, ten thousand..."

LAN Yin silently counted the zeros followed by her income, and then she was in a good mood, and silently smiled~

At this moment, she knew that the large amount of recorded news was the surgical machine mailed by herself, which was successfully sold——
