Pang Xuelin opened his eyes, an unprecedented sense of clarity poured into front of him, the morning light outside the window was faint, the morning breeze blew in through the gap in the window, the curtains moved with the wind, Pang Xuelin could clearly see the patterns on the curtains, and even vaguely smelled a trace of the fragrance of grass and trees.

He closed his eyes and took a greedy breath.

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

The reward of the system is also very powerful, Pang Xuelin feels that everything he sees with his eyes has become clearer than ever, even clearer than when he wears glasses, just like a newborn baby, looking at the world for the first time.

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

But fortunately, his body does not seem to have the discomfort of living in a low-gravity environment for a long time, and his muscle strength is still there.

What the system should build should only be a mental space, and one's own spiritual body crosses to various planes, and the body is still preserved in reality.

Pang Xuelin thought as he picked up his mobile phone on the bedside table, and the time was displayed as 5:21 on October 6, 2019.

He spent six or seven years in the Martian world (five years on Mars and more than a year back), but in reality it was just over five hours.

But in reality, the body seems to be in a state of deep sleep, and Pang Xuelin does not feel very tired, but has a feeling of refreshment.

"Comfortable!"

Pang Xuelin stretched and got up from the bed.

After no one spoke on Mars for a long time, he was about to get aphasia.

After the arrival of the Ares 4 task force, after a year of training, Pang Xuelin slowly recovered his language state.

Pang Xuelin came to the bathroom, ready to wash, and when he looked up, he couldn't help but be surprised when he saw himself in the mirror.

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

But now, although Pang Xuelin's appearance has not changed much, after years of tempering in the harsh environment of Mars, Pang Xuelin has long faded from the immaturity of his student days, and the whole person seems to be refreshed, with a kind of calmness and perseverance that does not match his age.

Especially those eyes, dark and bright, clear and abnormal, with a faint sense of vicissitudes.

Pang Xuelin can't say whether this change is good or bad, but there is no doubt that the experience of The Martian has made him reborn.

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

It had been a long, long time since he had experienced everything on earth, the flowers and trees, the birds and flowers, and the hustle and bustle of the city......

In the past, Pang Xuelin liked to be quiet and didn't like that noisy environment.

But after living alone on Mars for so many years, he misses everything on Earth more and more, even the unpleasant car exhaust is fragrant in his nose.

As soon as he walked out of the door, the door on the opposite side suddenly opened, and Qi Xin, a beautiful neighbor who had not seen him for many years, also walked out.

"Junior brother, you ...... Why are you so early today? ”

Qi Xin's eyes swept over Pang Xuelin, and then met Pang Xuelin's eyes, the whole person seemed to be electrified, and quickly turned his head, not daring to look at Pang Xuelin.

A hint of blush appeared on Qi Xin's face, and he tried to suppress his pounding heart.

It's strange, although his cheap junior used to be a little handsome, but today he seems to have changed a person, those eyes are too good-looking, and his temperament is also very charming, not much worse than those big stars.

Pang Xuelin naturally didn't know Qi Xin's thoughts, but he was a little strange Qi Xin's reaction, and said with a smile: "Senior sister, are you going to go out for an early exercise?" ”

Today, Qi Xin is wearing a ponytail, wearing a T-shirt and shorts sportswear, revealing a pair of white and tight thighs, although he is not tall, only in his early sixties, but the ratio of his thighs to his upper body is just right, his figure is well-proportioned, and he has a pair of white sneakers on his feet, which looks youthful and beautiful.

Qi Xin came back to his senses and nodded: "Yes, I get up early every day to run!" I've never seen you go out so early before, are you going to go out for a workout? ”

"Sort of!"

Pang Xuelin nodded.

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

"That'...... Why don't we do it together? ”

"Okay!"

Pang Xuelin naturally has no opinion, he originally planned to go out for a stroll and get involved in the popularity of the earth, but now that he is accompanied by an eye-catching beauty, he naturally won't mind.

"By the way, junior brother, didn't you go out during the National Day holiday? I went to Thailand with my classmates, originally thought that the tourist attractions in China were crowded, and it should be better abroad, but Thailand was the same, we played for a few days and came back, I only arrived at the school yesterday afternoon! ”

"I've had something to do, and I've been in school all this time."

"Aren't you still doing research, isn't that BSD conjecture already proven? No, a great mathematician like you might be in retreat again. ”

"It's not that exaggerated, I just don't really like to hang out!"

Pang Xuelin smiled faintly, he couldn't tell Qi Xin that he had been to Mars for a few years.

"What about your girlfriend? Don't you spend time with your girlfriend on vacation? ”

"Girlfriend? I'm still single! ”

I don't know why, hearing Pang Xuelin say this, Qi Xin actually felt a little joy in his heart.

You must know that Qi Xin's own conditions are excellent, over the years, there have been countless excellent men who have appeared beside her, but basically few of them make her feel excited.

Even including the previous Pang Xuelin.

Qi Xin is one year older than Pang Xuelin, although Pang Xuelin is excellent, but the student spirit is too heavy, giving people a relatively immature feeling, plus women have always matured earlier than men, therefore, Qi Xin just regarded Pang Xuelin as an ordinary friend at the beginning, and did not have much love between men and women.

It's just that she didn't expect that she hadn't seen her for a few days, Pang Xuelin felt like a different person to her, her eyes were clear and deep, faintly with a sense of vicissitudes, and with his young face, it formed a strange charm, which instantly hit Qi Xin's little heart.

"Senior sister, what about you? Did you go to Thailand with your boyfriend this time? ”

"Nonsense! I haven't been in a relationship yet, have I? This time I went with my girlfriends, but this time although there were many people, but it was quite fun, we also went to Phuket to play diving, I tell you, diving can be exciting......"

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

……

The two talked and laughed all the way downstairs.

Pang Xuelin enjoyed this feeling very much, if a girl showed some kind of closeness to him in the past, he would either be indifferent and pretend not to know anything, or directly refuse to make the other party die. Interpersonal interactions, relationships between men and women, are taking up his research time for him.

But now, after experiencing the near-death of the three-body plane and the predicament of the Martian plane, life in reality has become a haven for him to rest after his adventure.

Perhaps, it's not bad to have a girlfriend.

Pang Xuelin's gaze swept over Qi Xin's pretty face, and he said secretly in his heart.
