Huaguo, Linhai City, Shuxiang Community.

The weather in June is unusually hot and muggy. The clouds in the sky are thick and there is a faint tendency to gather into dark clouds. I wonder if a heavy rain is brewing.

In front of the window sill, Li Yang was reading a physics textbook.

"The first cosmic velocity (v1) is the speed that a spacecraft must have when moving in a circle along the earth's surface, also called the orbiting speed. According to mechanical theory, v1=7.9 kilometers/second can be calculated."

"When a spacecraft exceeds the first cosmic velocity v1 and reaches a certain value, it will break away from the earth's gravitational field and become an artificial planet orbiting the sun. This speed is called the second cosmic velocity, also known as the escape velocity. It can be calculated according to mechanical theory

The second cosmic velocity v2 = 11.2 kilometers/second..."

"The minimum speed required to launch a spacecraft from the surface of the earth, fly out of the solar system, and roam in the vast galaxy is called the third cosmic speed. According to mechanical theory, the third cosmic speed v3=16.7 kilometers/second can be calculated..."

…

When he first learned this, Li Yang was fascinated by whether the earth was the only one with life in the vast universe.

Many people think that the Earth is the only one, but others firmly believe that there are other lives outside the Earth. In their view, humans have very little understanding of the solar system so far, let alone the entire Milky Way and even other galaxies.

Compared to the entire universe, the Milky Way is just a drop in the ocean.

Regarding this issue, Li Yang had discussed it with his classmates for a period of time before and was quite interested in it.

However, Li Yang had no other thoughts in his mind at this time, but was preparing for tomorrow's college entrance examination.

More than ten years of preparation are just for the next two days.

After reading for a while, Li Yang turned on the TV, which was a column explaining medicine.

"I wonder if there is any progress in anti-cancer drugs?"

Li Yang was looking forward to it.

Cancer, this was once a nightmare for mankind. How many people talk about cancer. If you get cancer, you can basically be declared dead. It’s just a matter of how long it takes.

However, half a year ago, scientists from the largest international medical research institute on earth and many countries jointly announced that the anti-cancer hormone was successfully developed!

Whether it is early stage, middle stage, or even late stage cancer, just one dose of anti-cancer hormone will make the cancer cells in the body disappear quickly!

When this news was announced, it immediately shocked the world. Even now, news about anti-cancer substances breaks out from time to time.

However, although anti-cancer substances have been developed, it is very difficult to produce them due to various special reasons. Half a year has passed, and only more than a thousand doses of anti-cancer substances have been produced!

All in all, on average, only more than a hundred doses can be produced per month.

"There's new news!" While eating and waiting, Li Yang's eyes suddenly froze.

Sure enough, the latest news about anti-cancer hormones began to be broadcast.

"The latest news is that 180 doses of anti-cancer drugs were used in May, and a total of 180 patients with late-stage cancer were cured... The production of anti-cancer drugs is expected to increase to 200 doses in June..."

There were no big expectations, and the look of anticipation in Li Yang's eyes also disappeared slightly.

It seems that the anti-cancer hormone requires the use of a very precious material. That material is very scarce, so it is very difficult to make.

Slightly disappointed, Li Yang sighed inwardly.

After a few minutes, the meal was ready, and Li Yang was preparing to clear away the dishes.

"Dong dong dong."

Suddenly there was a knock on the door, and then a voice came.

"Xiaoyang, open the door."

Hearing this, Li Yang immediately stood up and opened the door.

Outside the door, a woman in her twenties was carrying something. Her face was obviously similar to Li Yang's.

"Sister, why are you here?" Li Yang asked, looking at the woman.

The person who came was none other than his sister Li Xue.

Li Xue is ten years older than him, and Li Yang was born after China opened its two-child policy.

Li Xue is now married and has a daughter.

Li Xue walked in carrying her things and said, "The company is on holiday, I'll come back and have a look. I went to the hospital to see Dad before."

Li Yang nodded and asked again: "Sister, have you eaten?"

"Eat." Li Xue glanced at the table and said, "Have you eaten yet? After eating, take a good rest and prepare for the exam tomorrow. I will take care of the things on the table."

She put down her things and started clearing the table.

Li Yang had no objection to this move, and Li Xue would tidy up the house every time he came back.

While helping to clean up, Li Yang asked: "Sister, how is dad's health?"

Hearing this question, Li Xue sighed slightly and said, "The condition has worsened a little."

Seemingly worried about Li Yang, she added: "But if you insist on taking medicine, you can still control it."

Li Yang's father is Li Guohai. He is considered to have achieved some success in his career. He previously opened a supermarket, but his health has changed and he now has terminal cancer.

Now, Li's father is in the hospital for treatment, and Li's mother is taking care of him in the hospital.

"Xiaoyang, stop thinking about these things and concentrate on reading. You also know what your parents expect of you. Getting good grades is the most important thing to them." Li Xue looked at his brother.

My younger brother has always had excellent grades since he was a child, and now he is always in the top three in his class at a key high school in the city, and within the top thirty in his grade.

It is easy to get into a key university with such scores.

"Sister, I know." Li Yang nodded.

As they were talking, suddenly both siblings looked at the TV.

On TV, interviews with people appeared at this time.

"Zhao Group Chairman Zhao Ganxing announced that he will enter the medical industry and spend 10 billion to establish a medical fund organization to help more people..."

The picture that appeared on TV was of a man in his sixties.

Zhao Qianxing is the biggest contributor to the Zhao Group. The group was founded by his father, but it grew and grew in his hands!

Twenty years ago, Zhao Group was one of the largest domestic companies!

At this time, the Zhao Group was even bigger. In the past ten years, Zhao Ganxing even occupied the title of the richest man in the country. Now his net worth is firmly among the top 50 in the domestic rich list.

Looking at the man being interviewed, Li Yang obviously had a complicated look in his eyes, and he clenched his fists slightly.

Not many people know that the Li family has a close relationship with Zhao Qianxing.

In terms of relationship, Zhao Qianxing was his and Li Xue's biological grandfather.

Li Yang's mother, Zhao Rou, is the daughter of Zhao Qianxing.

In other words, in terms of relationship, Li Yang and Li Xue are the direct grandchildren of Zhao Qianxing.

However, because of some things that happened back then, Zhao Qianxing was furious and kicked Zhao Rou out of the house.

This kind of thing is really unbelievable. Nowadays, we are not in ancient times, and we pay attention to being well-matched.

Even if Zhao Rou chooses to be with Li Guohai, Zhao Qianxing won't be so angry.

But Zhao Qianxing was so angry, so furious that many people were surprised.

Previously, Li Guohai was diagnosed with cancer, and Zhao Rou took Li Xue and Li Yang to ask Zhao Qianxing for an anti-cancer drug.

Although anti-cancer hormones are extremely rare, as one of the top richest men, Li Guohai would not have any difficulty getting one.

However, in the face of Zhao Rou's kneeling plea, Zhao Qianxing showed no expression on his face and walked away indifferently without even looking at her.

Until now, Li Yang has not forgotten that indifferent look.

"This Zhao Qianxing doesn't care about his relatives, but he is keen on doing charity on TV..."

Li Yang looked at the smiling Zhao Qianxing in the picture and sneered in his heart.
