The first day of the tenth month of the lunar calendar.

Zheng Yuanli, who goes by the pseudonym Zheng Wuyi, went to Cambridge as the youngest scholar in the exchange group, and the three-month academic exchange and study was completed.

The topic of this exchange is that next year's particle collider will be completed in the European Union, and I hope that China will also send representatives to participate in the research. There is a general understanding in the physics community that only such microscopic experiments are the future of physics.

The only way to move towards the infinite universe is to start with the tiniest particles.

They were to return to Beijing via London.

Probably because of the low latitude of the UK, it always gets dark very early in winter, and by 3 p.m., the sky gradually starts to darken.

On the platform, Zheng Wuyi looked at his watch, which was a Tudor watch, with twelve earthly branches engraved on the dial. It's a lot like the pocket watch that my father once owned and wanted to give him away, but it wasn't.

The time is 16:30.

Thirty minutes to go.

Most of the scholars who came with him were older, except for Professor Guo Moru, who was an associate professor in college. He still has the same messy hair as before.

"The train will arrive in ten minutes."

"It's no different, are you reading too many books now, and you are becoming more and more like a graduate student. Don't come out and relax with a nerve, it's also good for yourself.

Guo Moru has always admired his student, who is gentle and knowledgeable, but since he seemed to have a distance from others three years ago, it has become even more difficult for him to get close to others.

This student is just immersed in academics, seriously studying all the mysteries of the universe. It seems that everything in this world has nothing to do with him. It seems that he has never been bothered by any mundane things.

It is not too difficult for such an excellent student to publish academic papers and obtain graduate qualifications. It's just that it seems, none of this is what he wants. It seems that there is nothing he wants in this world anymore, and the only time he is a little happy is when he mentions his brother, with a smile on his face.

It's too contemptuous, what about his father and mother?

Or are there any other relatives in the family, brothers, sisters, uncles, aunts, etc.?

Guo Moru wanted to ask, he knew that Zheng Wuyi would also answer, but he felt that asking this question would only make each other embarrassed. It's better not to ask.

Maybe it's because he has too many mysteries. So everyone respects this young man who is very smart and a little like the autumn breeze. After all, no one wants to get in trouble.

Ten minutes later.

The train slowly entered the station.

Zheng Wuyi waited for the old professors to go up one by one. Take a look from time to time to see if anyone needs help.

He didn't get in until everyone was in the car.

The old professors in the car happily exchanged their insights and insights on this academic exchange, and felt that maybe in a few decades physics there will be new discoveries and great progress.

There was an old professor who even joked.

"It's not good, when a light-speed particle hits a wormhole, everyone will be able to travel directly through time and space!"

"If it's a black hole, everyone can go directly to God!"

Inside the carriage, everyone laughed.

At this time, several Englishmen in the carriage felt a little unbearable.

The British, by nature, are a quiet and conservative people, and their character can be seen from the spacing of their estates and houses, and they pay great attention to personal space between people.

And arguing with others is considered very rude in British culture.

A young man with curly hair and freckles in England said to some of the older gentlemen.

"Shut up, Chinese pig. （shut up！ Chinese pig！ ）”

At this time, several old professors were very embarrassed all of a sudden. It is indeed understandable to follow the customs of the locals, and when you go to other people's places and do not abide by other people's culture, you will be scolded. quarreled, but it caused more shame for several old professors.

So several old professors smiled awkwardly and waved their hands.

At this time, an old British lady sitting in the front row and thin turned to the young man in England just now.

"Be careful! Youngster! （watch your month! young man!）”

The young man turned his head and pointed at the old lady.

"Hey! You don't care! ”（hey！ it’s not your business！ ）

The old lady gave a blank look, waved her hand, turned her head and shook her head.

At this time, Zheng Wuyi walked in front of the old lady. Took a small Chinese knot and said to the old lady.

"We're sorry for arguing you, it's a little gift, I hope it brings you good luck."

The old lady smiled at Zheng Wuyi.

"What a good boy."

Then Zheng Wuyi smiled at the young Englishman again and took out a Chinese knot.

"A little gift, I'm sorry."

The young Englishman slapped the Chinese knot in Zheng Wuyi's hand.

"Neuropathy." （fucking alien）

Then, the young man left the carriage. Zheng Wuyi bowed his head and bent down to pick up the Chinese knot that the young man had broken to the ground and picked it up again.

Whispered in Chinese.

"In China, the Chinese knot symbolizes that the family can always be together."

All this was seen by Guo Moru, who was originally sitting next to Zheng Wuyi, and of course he knew the meaning of the Chinese knot. It's just strange why he has so many Chinese knots on him.

"You brought it to the professor who communicated?"

"Yes."

"Where did you come from?"

"I did it myself."

The train rumbled and galloped, and Zheng Wuyi looked at the outside world. The UK has an oceanic climate and is not too cold. But there was also a slight chill.

The extremely low latitude seems to make the starry sky too close to this world. If you open the window of the train and stretch out your palm, it seems that you can pick one and hold it in the palm of your hand. Stars hundreds of millions of years away have their own fate, and even some stars have died before they transmit their light to the earth.

Light has speed, but gravity is faster than light.

This is the cause and effect of many stars.

Therefore, Western astrology uses the stars in the sky as a medium to predict the fate of human beings.

In the dark, human beings are also pulled by the gravitational pull of the stars.

Thinking like this, Zheng Wuyi opened a copy of "The Complete Works of Sherlock Holmes", if you go to London, you should go to Baker Street. As for the food, there is really nothing that meets the taste of the Orientals.

Roadside snacks such as fish and chips are okay, and pirate pies, which are bread with meat sauce, can be seen as British buns, but in fact, the British eat the most Turkish kebab now.

(This has a lot to do with the local demographics in the UK.) I can't talk about it in detail, and then I want to be harmonized, from food to culture, I can talk to you for a day, let's get back to business and tell stories. ）

The train arrived at the station before it reached London, Essex, and at this stop, the old lady walked up to Zheng Wuyi, who was reading, before getting off the train.

Across Guo Moru, he handed him a piece of chocolate.

"Chocolate makes people happy, my kid."

Zheng Wuyi took the old lady's chocolate and wanted to get up to say thank you, but found it inconvenient. The other party also realized that it was not very convenient for Zheng Wuyi, who was sitting by the window. Wave your hand and signal for him to sit down.

Guo Moru felt a little redundant.

At this time, the old lady also handed him a piece of chocolate.

"This piece is for you, take care of him."

Then the old lady smiled kindly at them and pushed a small suitcase towards the door.
