When Pang Xuelin opened his eyes, an unprecedented sense of clarity poured into his eyes. The morning light outside the window was dim, and the morning breeze blew in through the gaps in the window. The curtains moved with the wind. Pang Xuelin could clearly see the patterns on the curtains, and even vaguely smelled the fragrance of plants and trees.

He closed his eyes and took a greedy breath.

The natural atmospheric environment created by countless life activities on Earth is many times more comfortable than the artificial atmosphere on Mars.

The system rewards are also very powerful. Pang Xuelin felt that everything he saw in his eyes became clearer than ever before, even more clearly than when he was wearing glasses, just like a newborn baby, who opened his eyes to the world for the first time.

Pang Xuelin slowly got up from the bed and suddenly returned to reality. The gravity environment of the earth made him a little uncomfortable.

Fortunately, his body does not seem to have the discomfort caused by living in low gravity environments for a long time, and his muscle strength is still there.

The system should be built just a spiritual space. When your own spiritual body travels to various planes, the body is still preserved in reality.

Pang Xuelin thought to himself, pick up the phone on the bedside table, and the time was displayed at 5:21 on October 6, 2019.

He spent six or seven years in the Mars rescue world (five years on Mars, more than a year of return), but in reality he only spent more than five hours.

But in reality, my body seems to be in a deep sleep state. Pang Xuelin did not feel very tired, but instead felt refreshed.

"Comfortable!"

Pang Xuelin stretched and got up from the bed.

He was almost aphasia after no one spoke on Mars for a long time.

After the Ares 4 mission team arrived on Mars, Pang Xuelin almost didn't know how to communicate with them in language. After a year of training, Pang Xuelin slowly regained his sense of speech.

Pang Xuelin came to the bathroom and was about to wash up. When he looked up, he was shocked when he saw himself in the mirror.

In the past, Pang Xuelin gave people a bit gentle and elegant feeling, and even because of his age, he was a little student-like and seemed more immature.

But now, although Pang Xuelin's appearance has not changed much, after years of hardship in the harsh environment of Mars, Pang Xuelin has long lost the immatureness of his student days, and his whole body seems to be completely renewed, with a kind of calmness and perseverance that is inconsistent with his age.

Especially those pair of eyes, they were black and bright, extremely clear, and there was a hint of vicissitudes of life.

Pang Xuelin couldn't say whether this change was good or bad, but there was no doubt that the experience of Mars rescue gave him a complete change.

After changing into sportswear, Pang Xuelin was about to go out for a walk.

It has been a long time since he experienced everything on the earth, including flowers, plants, trees, birds, flowers, hustle and bustle in the city... Everything is missed by him.

In the past, Pang Xuelin liked quietness and did not like the noisy environment.

But after living alone on Mars for so many years, he has missed the real world more and more. Even the unsmelling exhaust of cars is fragrant in his nose.

Pang Xuelin opened the door and just took a step when the door opposite suddenly opened. Qi Xin, a beautiful neighbor who had not seen for many years, also walked out.

"Hey, junior brother, you... why are you so early today?"

Qi Xin's eyes swept over Pang Xuelin, then met Pang Xuelin's eyes, and his whole body seemed to have been electrocuted. He quickly turned his head and did not dare to look at Pang Xuelin.

Qi Xin's pretty face turned red and she thought to herself: "It's strange. Although this cheap junior was a little handsome before, she seemed to have become a different person today. Her eyes were so beautiful, and her temperament was also very charming, no worse than those big stars."

Pang Xuelin naturally didn't know Qi Xin's thoughts, but he was a little surprised by Qi Xin's reaction and smiled and said, "Senior sister, are you going to go out for early exercise?"

Today, Qi Xin tied her ponytail and wore a T-shirt and shorts sportswear, revealing a pair of white and tight thighs. Although she was not tall, she was only over 1.6 meters tall, but the ratio of her thighs to her upper body was just right, her figure was well shaped, and she was a pair of white sneakers on her feet, looking young and beautiful.

Qi Xin then came to his senses and nodded and said, "Yes, I get up early every day to run! I haven't seen you go out so early before, are you going out to exercise?"

"That's right!"

Pang Xuelin nodded.

Pang Xuelin has no habit of exercising and looks thin and weak, but after being an astronaut for so many years, Pang Xuelin naturally knows how important a strong body is to a person.

"Then...why should we join us?"

Qi Xin has some expectations.

"Okay!"

Pang Xuelin naturally had no objection. He originally planned to go out for a walk and get involved in the popularity of the earth. Now that he has a beautiful girl who is pleasing to him, he naturally wouldn't mind it.

"By the way, my junior, haven't you gone out during the National Day holiday? My classmates and I went to Thailand. I originally thought that domestic tourist attractions would be crowded and abroad would be better, but the same goes for Thailand. We came back after a few days. The school I just arrived at yesterday afternoon!"

Qi Xin said.

Pang Xuelin said: "I have something to do, I have been staying in school for this time."

Qi Xin smiled and said, "You are not still doing research, right? Didn't that BSD conjecture prove it? No, a great mathematician like you might start to go into seclusion and work on projects again."

"It's not that exaggerating, I just don't like going out!"

Pang Xuelin smiled faintly and thought to himself, I have been to Mars for a few years and I have already had enough fun!

"What about your girlfriend? Don't you accompany your girlfriend during the holidays?"

Qi Xin looked at Pang Xuelin Dao without blinking.

"Girlfriend? I'm still alone!"

For some reason, after hearing what Pang Xuelin said, Qi Xin felt a little secretly happy.

You should know that Qi Xin has excellent conditions and high vision. She has never been in a relationship for so many years.

Even for Pang Xuelin before, she only admired the academic masters and did not have much affection between men and women.

Qi Xin is one year older than Pang Xuelin. In her eyes, Pang Xuelin is excellent, but she is too young and gives people a feeling of immatureness. She is also a top student who is addicted to research all day long and is not a suitable boyfriend.

But she never expected that she hadn't seen her for a few days, and Pang Xuelin felt like she had changed her personality. Her eyes were clear and deep, her temperament was calm, and she had a little vicissitudes. Coupled with his young face, it formed a strange charm, which instantly hit Qi Xin's little heart.

For the first time, Qi Xin wanted to take the initiative to pursue a boy.

"Senior sister, what are you thinking? Are you going to Thailand with your boyfriend this time?"

Pang Xuelin had a gentle look and said with a smile.

Qi Xin blushed and hurriedly said, "Nonsense! I haven't had a relationship yet! I went with my best friend this time, but although there are many people this time, it's quite fun. We also went to Phuket to dive. I tell you, diving is exciting..."

"Oh, then next time I have a chance, I must go and have a look!"

...

The two of them went downstairs talking and laughing.

Pang Xuelin enjoyed this feeling very much. In the past, if a girl showed a certain sense of intimacy with him, he would either act indifferently and pretend to know nothing, or he would directly refuse, making the other party give up.

For him, interpersonal communication and relationship between men and women are taking up his research time.

But now, after experiencing the triad plane of death and the dilemma of the Martian rescue plane, life in reality has become a harbor for him to take risks and rest.

Perhaps, dating a girlfriend is also good.
