Roaming the universe, all thanks to your many dark skills!

Solar Day 221.

Rosen didn't know what Mark talked about with NASA, but in any case, he started to transform the Mars rover under the command of that group of smart people.

For example, drilling a hole in the roof, then stomping on it hard, and falling into the car with a plop, or installing an airbag on the roof...

Although Rosen could teleport Mark directly there, the latter and NASA obviously still felt that it was more reliable to drive a rover there.

Naturally, Rosen was too lazy to bother trying to please someone else.

After all, after coming out of the giant pit, although the two appeared to be the same as before, there was already a gap in their hearts, and it was difficult for them to be as close as before.

Maybe this is human nature.

Solar Day 227.

Mark is still busy.

As planned, Hermes bypassed the Earth, picked up a space capsule with the Chinese and American flags on it, and headed straight for Mars.

What awaits them will be a long space journey of more than 300 days.

Solar Day 461.

Mark prepared everything to keep him alive.

In addition to food, there are also oxygen supply, water circulation system, atmosphere regulator, battery, solar panels...

After taking a hot shower, he changed into a clean spacesuit and prepared to set off for the designated location - Ares 4.

Thanks to Rosen's occasional help, he is not much different now than he was seven months ago. He is definitely not like in the original plot where he became extremely thin due to hunger.

In addition, after seven months of getting along, the relationship between Rosen and Mark has eased a lot.

However, the incident involving Xing Tianji was like a thorn that stuck in each other's hearts and could not be easily erased.

Knowing that Mark was leaving today, Rosen came to see him off.

"I've been thinking about the laws and regulations on Mars." Mark smiled and said to Rosen: "There is international law that no country can say that anything outside the earth belongs to them."

"Another treaty says that if you are not in any territory, you must follow the laws of the sea, so Mars should be considered 'international waters'."

"Now NASA is a non-militarized organization in the United States, and the research station belongs to it. But when I walked out of the research station, I was in international waters, and then it became interesting. I was about to go to Schiaparelli Crater and requisition the Ares 4 spacecraft, and no one gave me direct instructions to do so."

This was because he accidentally dropped the onboard communicator while modifying the Mars rover, causing him to lose contact with NASA again.

Mark chuckled, his full beard moving back and forth. "I can't be given any instructions until I'm aboard Ares 4. That would make me take over a ship without permission in international waters, which by definition makes me a pirate."

At this point, he smiled and looked at the camera recording his log, and said, "Mark Watney, Space Pirate Day 461."

Then he shut down the system, ending the long-running log.

"Rosen, I'm leaving." Mark looked at Rosen with mixed emotions in his eyes. "Although I know I will see you often in the future, I still have to say goodbye to you as usual. Thank you for your care for so long. Although you can't go with me, I still wish you good luck."

"The same blessing goes for you," Rosen said.

The two hugged each other, then Mark closed the door of the living cabin, boarded the rover, waved to Rosen, and drove forward.

After watching Mark leave, Rosen also began to prepare for departure.

He did not plan to dismantle the container villa and take it away, but instead wanted to leave it for the Chinese who would land on Mars in the future.

In addition to food, drinking water and various seeds, Rosen also left two mechanical scorpions in a secret place.

If the Chinese astronaut really came here and was lucky enough, he should be able to find these two scorpions and study them. Perhaps this would provide strong enough support for China's technological progress in this world.

As for the others, such as the mechanical spider and mechanical tiger, Rosen did not intend to keep them.

It's not that he is stingy, but there is no benefit in taking too big a step.

I don't know if I will have a chance to come back, but if I do, I hope things will change for the better, Rosen thought.

In addition, Rosen also left some words, but there is no need to say what he wrote.

In short, people leave their names behind and wild geese leave their voices behind. Of course, when they come to this world, they will leave some traces behind.

Solar Day 538.

Although there were twists and turns along the way, Mark eventually reached the Schiaparelli crater and found the Ares 4 spacecraft. He then began to dismantle it frantically according to the advice of NASA experts, with the sole purpose of reducing weight.

Perhaps it is because Mark's current weight is not as light as in the original plot, which also caused a headache for the experts, and they tried every means to reduce the weight from the aircraft.

Rosen would occasionally teleport over to help him.

Solar Day 562.

This was the day Mark was scheduled to leave Mars.

Rosen brought a sumptuous lunch to see him off.

Because she had to go to heaven later, she didn't drink. In addition to cooking a few dishes, Rosen also cooked a bowl of dumplings for her.

"Last time I heard from a friend that dumplings are good for going out and noodles are good for coming home." Rosen pointed at the dumplings and said, "I made these myself. I wish you a safe journey."

"Thank you." Mark picked up a dumpling skillfully with chopsticks, bit half of it, dipped it in vinegar, and put it in his mouth. At the same time, he took a clove of garlic and ate it with a crunch.

"Won't you be annoyed that your teammates will be disgusted by your bad breath when you meet up later?" Rosen said with a smile.

"It's not just my bad breath that they dislike. My body stinks so bad that it's killing me." Mark said, pointing at the dumplings, "Didn't you say that dumplings taste half as good without garlic? For this meal, the bad breath is worth it."

"Ha ha……"

Mark was eating dumplings when he suddenly thought of something. He took out a piece of paper, wrote a line of words and stuck it in the car: "Whoever it is, treat this Mars rover well. It saved my life, Watney."

After eating and drinking, Mark got off the rover and climbed onto the Ares 4 spacecraft next to it.

Rosen drove the rover a little further away and then teleported to the aircraft.

"Rosen, do you really want to go up with me?" Mark asked.

"That's right." Rosen nodded and said, "I'm worried that this thing alone may not be able to send you over smoothly, but with me, it won't be a problem."

"Aren't you going back to Earth with me?" Mark asked, "In fact, having you here doesn't mean much to the Hermes. Don't you want to go back and see your family?"

"My family..." Rosen thought for a moment and said, "They are not here."

At this point, he suddenly remembered something and said, "Let me show you something interesting."
