"Knock Knock Knock ......"

The tapping sound is soft.

But Li Yan was still taken aback.

It shouldn't be, haven't all the teachers already said hello, and no one in the 211 lab has classes in the afternoon!

After a moment's pause, he immediately spoke: "Please come in!" ”

Perhaps hearing the response, the laboratory door was opened, and a middle-aged man in a white lab coat with gold-rimmed eyes walked in.

It was Li Yan's previous chemistry molecule teacher: Wang Gang.

"Teacher? How did you have time to come? ”

Li Yan immediately took off his mask, and he still had a lot of respect for his professional enlightenment teacher.

"I happened to be in the lab next door to you, and I came over to see your research."

Wang Gang grinned, still as amiable as when he was in school.

"Teacher, you sit down first."

Li Yan handed over the chair and said casually: "I opened a technology company, mainly researching high-end biomolecular synthesis, as well as chemical molecules, this is a stone I received from a private person, the composition in it is very different from the earth's rocks, it may be a meteorite." ”

"Oh? Yes! ”

When Wang Gang heard this, he immediately became interested.

Although he is in the field of chemical molecules, he also has some knowledge of meteorite composition, "Huh! The structure of the iron molecule is very special, it really doesn't look like the earth, it should be a meteorite, and it's a red meteorite, it costs a lot of money, right? ”

"It's okay!"

Li Yan snorted.

"I have a classmate who specializes in meteorites and works at the Modu Observatory, I can give you his contact information, if you don't understand, you can ask him!"

After Wang Gang left the microscope, he said casually.

Teacher, you are really my lucky star!

Li Yan was so excited in his heart that he was dying, he wasn't really a friend who asked to teach the teacher, with his current level of elementary alchemy, I am afraid that few molecular scientists on the earth would dare to argue with him!

What excites him is that he can get in touch with the meteorite circle through his teacher's friends!

You must know that although meteorites are expensive, there is no way to sell them.

Unless you are like those who report and go on the news, hyping up the sky-high meteorites they have picked up, they use their fame and passively wait for buyers to come to their door.

But in doing so, time is too slow, and on the other hand, Li Yan doesn't want to make such a big move, so that everyone's focus is on himself, which is easy to get into trouble.

Therefore, using insiders to find buyers is the most reliable and fastest way.

You must know that at present, there are only about 10 professional-level people who play meteorite collection in China.

10 pcs!

If he had gone to find it himself, he wouldn't have to find the Year of the Monkey unless he cooperated with the government.

And if the teacher has acquaintances here, that's much easier!

"Yes, thank you so much, teacher!"

Li Yan thanked him twice, and immediately obtained the mobile phone number from Wang Gang.

After Wang Gang left, he began to continue studying the isotopes of radioactive atoms.

You must know that with the current level of science and technology on the earth, the field of microscopic molecules is already the limit, that is, protons and atoms.

In addition to using protons to define molecular chemical properties, the isotopic arrangement of atoms is also an important index, such as the half-life of radioisotopes, which is the most accurate means to verify the existence time of substances.

As the world of origin is full of mystical origin energies.

The chemical properties of the molecule are slightly different from the earth, which doesn't matter, anyway, just push the pot to the meteorite, the material of the alien planet has many differences from the earth's material.

But the half-life can't be fooled.

At the very least, it can verify the time origin of the meteorite, too long or too short, it is not good, the solar system, the earth's existence years, there are currently speculative intervals.

If the matter of the origin world is far beyond the existence of the solar system, or it is very short, and it looks like a newly conceived nebula, it is too!

Fortunately.

Li Yan used alchemy to explore several radioactive elements, and the calculated time was about 2 billion years, which was basically reasonable.

"It's a pity that this is only a sample of a vein in the jungle, and it can't represent the entire Dinosaur Island, otherwise, a few more samples for calculation may be able to roughly guess the formation age of the origin world."

You know, the earth has been around for about 4.5 billion years, while humans have only been around for 25 million years.

25 million years, the evolution of scientific and technological civilization to this point.

I don't know how many years it took for the civilization of the origin world to reach such an advanced height.

Looking at the blue spar on his wrist, Li Yan's eyes narrowed and fell into deep thought.

Evening.

Seeing that it was time to make an appointment with Gu Qing.

Li Yan took the sample and left the school.

On the way, he contacted the observatory friend that the teacher said: Zhao Ming, who said that he had been at work for the past two days, and if he was in a hurry, he could go directly to the observatory to find him.

Li Yan thanked him twice and said that he would visit tomorrow.

It's five o'clock.

He came to the restaurant that Gu Qing gave him on WeChat, which was a high-end local dish, and it was also a feature of the magic capital.

The restaurant is located on the top floor of a luxury hotel on a lively shopping street.

Li Yan took the elevator and came all the way.

As soon as you enter the restaurant, you will be greeted by the luxurious decoration of old Shanghai, with dark red wood floors, high-end black dining tables, and white upholstered seats.

Next to it, the huge transparent floor-to-ceiling windows can overlook the prosperity of the entire commercial street.

At this time, it is dusk.

While eating the food, looking at the orange sky in the distance, and those bustling shopping malls that have just turned on the lights, it has a different flavor.

Li Yan was led to the window by the waiter all the way.

Before he could come over, Gu Qing had already seen him first, and raised his hand with a smile to say hello.

Stop.

This greeting made the other diners around him immediately move their eyes to him.

You must know that no matter where beauty goes, it is the focus of people's walking.

What's more, Gu Qing is wearing a black hip-wrapping dress tonight, highlighting her fair skin and bumpy figure, which is particularly perfect, and it is strange that it is not eye-catching!

"You've been waiting for a long time, haven't you?"

After Li Yan sat down, he made a general opening sentence.

"I also just arrived, I know that your wound has just been treated, you can't eat too spicy, this food is relatively light, I don't know if you like to eat it!"

Gu Qing smiled slightly.

Then, the waiter came over with the menu.

Li Yan still shirked a few times as usual, and he didn't have much of the heart to eat now.

Since he knew that there was a way to sell meteorites, he put all his thoughts on tomorrow.

"Let's do this first!"

After Gu Qing finished ordering, she got up with her skirt, "You sit down first, I'll go to the bathroom!" ”

"Okay."

Li Yan nodded, and then looked out the window.

And just when he was stunned, suddenly, a voice that made him extremely disgusting before suddenly reached his ears:

"Yo! Such a coincidence, isn't this Li Yan! ”
