The red sun sets in the west, and the train goes away, bringing with it a large number of yellow leaves and the bleakness of autumn in the vibration of the rails.

Wang Xuan watched until the train gradually disappeared, then he retracted his gaze and sent off several classmates.

Since then, they will be separated from each other, and it is unknown how many years it will take for them to meet again, and some people will never meet again.

Around, some people are still waving slowly, and have not let go for a long time, while others are silent and quite sad.

After four years of college, we have walked together, and the accumulated friendship is always difficult to give up.

The afterglow of the setting sun shines obliquely on the falling yellow leaves, and the light and shadow are mottled, interweaving a sense of the passing of time.

A pretty girl turned around and secretly wiped away the tears behind her glasses.

In this special era, they will go back to their own places after graduation, and may never meet again in this life.

The autumn wind blows, and the yellow leaves are messy and fluttering.

In this season, some people are frustrated, and some are proud.

Four months after graduation, some people stayed in this city with a bright future, while others waited and persevered in anxiety, and more people left with a sense of loss and returned to their hometown.

Wang Xuan was walking on the way back, wondering where he would go.

The streets were old, and the sycamore trees on both sides of the road dropped leaves in large pieces, covering the ground.

Some people walked side by side with him and complained for him: "Why is it that you are not among those who stayed? They actually gave up on you!"

As a classmate and good friend, in Qin Cheng's view, Wang Xuan would be selected whenever there was a quota.

After the results came out, many people felt complicated, and Wang Xuan was not selected.

"Let's not talk about me. How are you? Is there a result?" Wang Xuan asked him.

Qin Cheng whispered to him that his family had asked for help, and he might go to Xinyue.

"Xinyue, the other side of deep space, I don't know if we can see each other again in the future." Wang Xuan stopped, and all the friends around him were going far away.

He was tall, not thin, well-proportioned and strong. In the sunset, he had a light golden glow on his body, and his eyes were clear and bright.

"I will come back, and we will definitely meet again." Qin Cheng was an emotional person, and he was reluctant to leave his hometown, especially when he thought that it would be difficult to see his friends again, and he felt a little uncomfortable.

"Call me when you come back!" Wang Xuan hugged his shoulders tightly.

There was a choking sound in the wind, and Wang Xuan and Qin Cheng looked back and saw a male classmate who was very emotional.

He was pale, cried out, and shouted hard: "I really want to stay in this city, I want to wait for the last chance, I don't want to go back to my hometown like this!"

He has lived and studied here for four years, and he has worked hard, fighting, striving, planning his future, and wanting to find his place, but he couldn't stay after all.

He burst into tears.

The autumn wind was cool, and some classmates were depressed.

On the other side, a couple stopped and looked at each other, without words, but crying silently.

They will part ways, and from now on they will not be thousands of miles apart, but separated by a starry sky, and they may never see each other again in this life.

With tears on their faces, they hugged each other for the last time, and then there was only silence.

The city is large, but a little old, retaining traces of the old times. Many old trees on the roadside are very thick, and they are one or two hundred years old.

Relatively speaking, the whole city inherits the style of the past and has been preserved over the years.

In other places, some cities left over from the old times have been abandoned, uninhabited for a long time, and large areas of wasteland are covered with vines and thorns, and gradually submerged by grass and trees.

After returning to the campus, Qin Cheng was still angry for Wang Xuan and advised him to find someone to understand the reason why he was abandoned and ask for an explanation.

Even after graduation, they were allowed to live on campus until all the final candidates were determined.

This opportunity is rare. The selected people stayed in this city and waited, and will go to Nova soon, where there seems to be some unusual discovery.

Qin Cheng was not selected either. His family tried their best to give him only the opportunity to enter deep space.

He will go to Xinyue, the moon that revolves around Nova, which is the most important base outside Nova.

Qin Cheng whispered: "You know, even if there are only a few rumors there now, it has already made people who got the gossip in advance excited. No matter what, you must get a place!"

Under the moonlight, the shadows of the trees are swaying, and Wang Xuan stretches his body on the lawn. He is practicing the "scattering technique" of the old era. It is very practical and drives a large number of yellow leaves on the ground to fly up, filling the sky.

He did not stop, his movements were fast, but his breathing was steady, and he said: "I am waiting for the final result."

The deep space is boundless and the universe is vast, but it is cold and dead. Apart from the old land, people have only found another life star.

However, many years ago, the door to the new star was closed, and it was difficult for ordinary people in the old land to enter again.

Compared to the new star, some people gradually began to call this place the old land.

In the past, this place was called the Earth, the origin of mankind.

Perhaps it is indeed a bit "old", with many deserted cities, overgrown with weeds, and uninhabited.

All this was caused by a war in the old times.

When technology develops to a certain level, it will be very terrible if a hot war breaks out.

The prosperous world was destroyed and became extremely desolate and depressed.

At that time, a large number of people fled to space.

In fact, human technology at that time was not as brilliant as imagined. Before the war, a base had just been established on the moon.

Therefore, those who escaped could only temporarily use the moon as a foothold.

It was under this circumstance that humans suddenly achieved a large migration and discovered and entered a new star of life!

People in the old land still find it incredible.

Many people can't help but question that historical time node. What exactly caused the sudden explosion of cutting-edge technology?

All parties are very secretive.

Given the technological level of the time, neither steady-state wormholes nor warp engines and other black technologies could be realized in a short period of time.

Some people in Old Earth suspected that all the answers might be on the moon!

Unfortunately, the consequences of the hot war were too serious. The earth was half destroyed, and Old Earth had not recovered after so many years. Technology and other aspects seriously regressed, and it was impossible to land on the moon for a long time.

More than a hundred years later, the population of Old Earth has only recovered to about one billion, which is far from what it was back then. Many places are still very desolate.

In the early development of Nova, a large number of survivors of Old Earth were taken away, and a large number of talents left with them. This is also one of the reasons why Old Earth has seriously regressed and has not recovered for a long time, and this large migration lasted for decades.

It was not until more than a hundred years ago that Nova closed its doors.

In addition, the earth was devastated after the hot war, and the environment was extremely harsh. There were not many people left in Old Earth, so it was not easy to recover.

Under the dim moonlight, Wang Xuan was performing the "Sanshu". His movements suddenly accelerated. With a bang, his right hand left a clear handprint on a big tree. The tree trembled violently, and yellow leaves fell like a waterfall.

Qin Cheng was surprised: "Sanshu, you actually practiced something famous? They will definitely regret giving up on you!"
