Huaguo, Linhai City, scholarly community.

The June day was unusually hot, the sky was very thick with clouds, and there was a faint tendency to condense into the dark clouds, and I don't know if there was a torrential rain brewing.

In front of the windowsill, Li Yang was looking at a physics textbook.

"The first cosmic velocity (V1), the velocity that a spacecraft must have when moving in a circular motion along the earth's surface, is also called orbital velocity. According to the theory of mechanics, it can be calculated that V1 = 7.9 km/s. ”

"When the 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 escape velocity, according to the theory of mechanics, the second cosmic velocity V2 = 11.2 km/s..."

"The minimum velocity required to launch a spacecraft from the Earth's surface, fly out of the solar system, and roam the vast Milky Way is called the third cosmic velocity. According to the theory of mechanics, the third cosmic velocity V3 = 16.7 km/s..."

……

When he first learned this, Li Yang was fascinated in his heart, in the vast universe, is there only life on the earth?

Many people think that the earth is the only one, but the other part believes that there is other life beyond the earth. In their view, humanity has so far known very little about the solar system, let alone the entire galaxy or even other galaxies.

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

For this issue, Li Yang had a special discussion with his classmates for a period of time before, and he was quite interested in it.

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

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

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

"I wonder if there is progress in anticancer hormones?"

Li Yang looked forward to it in his heart.

Cancer, this is a nightmare for human beings, how many people talk about cancer discoloration, if you have cancer, you can basically declare you dead, it's just a matter of time.

However, half a year ago, scientists from many countries, the largest international medical research institute on the planet, jointly announced that anticancer drugs had been successfully developed!

Whether it is early, intermediate, or even advanced cancer, only one dose of anticancer is needed to quickly disappear the cancer cells in the body!

When this news was announced, it directly caused a shock to the world, and even now, news of anticancer hormones has broken out from time to time.

However, although anticancer hormin has been studied, it is very difficult to produce it due to various special reasons, and half a year has passed, and the total number of anticancer hormin produced is only more than 1,000 doses!

On average, only a little more than a hundred doses can be produced in a month.

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

Sure enough, the latest news about anticancer hormones began to be broadcast.

"The latest news, in May, 180 doses of anticancer were used, and a total of 180 patients with advanced cancer were cured... It is expected that the production of anticancer hormones will be expected to increase to 200 doses in June..."

There was not much expectation, and the look of expectation in Li Yang's eyes also disappeared slightly.

It seems that anticancer agents require the use of a very precious material, which is very scarce, so it is very difficult to make.

Slightly disappointed, Li Yang sighed in his heart.

Within a few minutes, the meal was ready, and Li Yang was about to clean up the dishes and chopsticks.

"Knock knock."

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

"Xiaoyang, open the door."

Hearing this, Li Yang suddenly got up and opened the door.

Outside the door, a woman in her twenties was carrying something, and her face was obviously a little similar to Li Yang.

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

The person who came was his sister Li Xue.

Li Xue is ten years older than him, and after China opened up the two-child policy, he had Li Yang.

Now Li Xue is married and has a daughter.

Li Xue walked in with her things and said, "The company is on holiday, I'll come back to take a look, I went to the hospital to see my dad before." ”

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

"Eat." Li Xue glanced at the table and said, "Have you eaten well?" After eating, I will rest well and prepare for tomorrow's exam, and I will get the things on the table. ”

She put down what she was holding and began to clean up the table.

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

While helping to clean up, Li Yang asked, "Sister, how is Dad's physical condition?" ”

Hearing this question, Li Xue sighed slightly and said, "The condition has deteriorated slightly. ”

As if worried about Li Yang, she said again: "But if you insist on taking medicine, you can still control it." ”

Li Yang's father's name is Li Guohai, and he has a small career achievement, and he opened a supermarket before, but his body has changed, and now he has terminal cancer.

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

"Xiaoyang, don't think about these things, concentrate on reading, you also know what your parents expect from you, and getting a good score in the exam is the most important thing for them." Li Xue looked at her younger brother.

My younger brother has had excellent grades since he was a child, and now he is always in the top three in the city's key high school class, within 30 in the grade.

It is easy to get into a major university with such results.

"Sister, I know." Li Yang nodded.

As he was talking, suddenly both siblings looked at the TV.

On TV, interviews about characters appeared at this time.

"Zhao Qianxing, chairman of Zhao's Group, announced that he would enter the medical industry and set up a medical fund organization with 10 billion yuan to help more people..."

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

Zhao Qianxing, the biggest hero of the Zhao Group, his group was founded by his father, but it developed and grew in his hands!

Twenty years ago, Zhao's Group was one of the giant enterprises in China!

At this time, the Zhao group was bigger and bigger, and in the past ten years, Zhao Qianxing even occupied the title of the richest man in China, and now his worth is also firmly in the top 50 of the domestic rich list.

Looking at the man who was interviewed, there was obviously a hint of complexity in Li Yang's eyes, and he clenched his fists slightly.

Few people knew that their Li family had a lot to do with this Zhao Qianxing.

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

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

In other words, in terms of relationship, Li Yang and Li Xue are the granddaughters of Zhao Qianxing's relatives.

However, because of some things at the beginning, Zhao Qianxing was furious and expelled Zhao Rou directly from the house.

This kind of thing is really incredible, now is not ancient times, pay attention to the right person.

Even if Zhao Rou chooses to be with Li Guohai, Zhao Qianxing will not be so angry.

But Zhao Qianxing was so angry, so angry that I don't know how many people were surprised.

Before, Li Guohai was diagnosed with cancer, and Zhao Rou took Li Xue and Li Yang to beg Zhao Qianxing to get an anti-cancer hormone.

Although anticancer hormone is extremely rare, Li Guohai, as one of the top richest people, really wants to get one, and it is estimated that it is not difficult.

However, in the face of Zhao Rou's pleading to kneel, Zhao Qianxing did not have any expression on his face, and walked directly from the side indifferently, without looking at her.

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

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

Li Yang looked at Zhao Qianxing with a smile in the picture, and sneered in his heart.

Thinking of his mother's kneel down and pleading, and thinking of that indifferent gaze, this made him feel a trace of hatred when he was complicated by Zhao Qianxing's grandfather.
