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

Under Hou Lei's invitation, Rosen really didn't feel comfortable refusing the dinner, but he didn't rush to accept his invitation to go hunting in the mountains, and just said he would think about it later.

After he had the money, Rosen immediately rented a two-bedroom apartment near the Medical University. Although the place was not big, at least he didn't have to worry about his roommates noticing something every time he traveled back through time.

In addition, he also stored the purchased supplies in the rented house so that he could carry them with him at any time before the crossing.

Three days later, Rosen saw that the time was almost up, and immediately asked his assistant for detailed information about the next world.

"The next world to be adventured in is the world of The Martian. Please prepare in advance."

"This crossing will cost you some merit points."

"Now entering the countdown: 71:59:59."

Rosen's eyes almost popped out of his head when he saw the second system prompt. He immediately asked, "There are no big scenes in The Martian, and not many people appear. Apart from the protagonist, there are only the potatoes he planted on Mars. How come traveling there costs more merit points than the world I just experienced?"

"Because this is also a world with a lot of freedom. As long as you are brave enough to explore, you will always gain something."

“But I need to remind you again: risks and rewards go hand in hand. I wish you a happy adventure!”

……

Although Rosen felt somewhat unhappy, he still had to make the necessary preparations as the time of crossing was approaching.

Watch movies, look up information, and purchase a large amount of supplies, including but not limited to oxygen cylinders, masks, medicines, mineral water, rice, noodles, seasonings, meat, eggs, various fruits and vegetables...

Basically, Lawson buys everything that can be used for food, clothing, housing and transportation. The main purpose is to be prepared for any eventuality.

After all, according to the system's usual practice, he will most likely be thrown onto Mars to suffer with the male protagonist Mark Watney. If he doesn't prepare more food, drinks and other daily necessities, it would be terrible.

In addition, Rosen also purchased a variety of seeds, fertilizers and farm tools.

Although Rosen was born in the countryside, he had never done serious farming.

Fortunately, he still had the Farming Proficiency Level 4 that Old Hulu had given him. Although he had never been to the fields before, he still knew all the farm work like the back of his hand and was a real expert.

This also gave Rosen more confidence about farming life on Mars after the time travel.

In addition to preparing supplies, Rosen also carried out some targeted exercises.

For example, he looked up information and saw that the oxygen content on Mars was very low and the carbon dioxide content was very high, so it was definitely not suitable for ordinary people to breathe, otherwise they would die soon.

Rosen wondered if he could adapt to this low-oxygen, high-carbon dioxide environment in advance, so he began to exercise on his own.

The method is very simple. Just find a plastic bag to cover your mouth and nose and start breathing. After a short time, as the oxygen inside is gradually consumed, the carbon dioxide content will definitely increase dramatically.

I have to say that this feeling of gradually suffocating to death was really uncomfortable, but Rosen really gritted his teeth and persevered.

Although he worked himself to a great limit, he did not gain nothing, because after working for more than twenty hours, he received a system prompt.

"After repeated attempts and training, you have mastered a new skill: Hypoxic Breathing, Level 1, which allows you to maintain normal breathing in an environment with an oxygen content of less than 10% for a short period of time. The duration is 10 minutes. Vigorous activities will shorten this duration. After this time limit, your health will gradually decrease."

Rosen was quite satisfied with this skill, and at the same time he was thinking about whether he could acquire more new skills using similar methods.

In addition, he also specially lit up a passive skill belonging to the Druid: Oak Sage, which allows you to summon a useful nature spirit to help you and your belongings gain more life and resist the invasion of bad conditions, LV1, life 60, life +30%, cold resistance +10%, fire resistance +10%, lightning resistance +10%, poison resistance 10%, range 20 meters, mana consumption 15. "(Note)

"Note: Since it comes from nature, its amplification effect on plants and animals is more obvious."

After acquiring this skill, Rosen tested its effect in a house he rented.

That afternoon, he randomly bought a black magic flower for three dollars at the flower market. The flower was severely frostbitten due to the owner's negligence.

At that time, most of its leaves had fallen off, and the remaining ones were drooping. It looked like there was no hope of saving it, otherwise the owner would not have sold it so cheaply.

After Rosen brought it home, he summoned the Oak Sage.

The orange-red Oak Sage began to float around the room, and except for occasionally circling around Rosen, he stayed next to the Black Wizard most of the time.

After a night, when Rosen saw the Black Wizard again, he couldn't help but exclaim: It's so fucking awesome.

Because the black wizard who was dying yesterday has now regained his vitality.

New shoots sprouted from the fallen leaves, and the remaining leaves regained their firmness.

If Rosen hadn't seen it with his own eyes, he wouldn't have believed that it almost died.

This is enough to prove the usefulness of the Oak Sage, and makes Rosen more confident that his next rescue journey on Mars will become easier and smoother.

.....................

Humans achieved the first landing on Mars, and botanist Mark Watney, along with five other people, became one of the first lucky people to land on Mars.

Unfortunately, they had just been on Mars for a short time before they had to withdraw to Earth early due to a sudden and severe sandstorm.

But during the evacuation, Mark was hit by an antenna blown away by the strong wind.

Not only was his space suit pierced, but a hole was also poked in his body. He fainted immediately and, by some miracle, his life sensor was crushed.

This made his companions think that he was completely dead, and because the weather was getting worse and visibility was extremely poor, there was no way they could stay to search and check carefully, so they could only abandon his "body" and evacuate in a hurry.

When the rocket's tail flame disappeared into the dark night sky, a tall figure appeared beside Mark without warning.

“It’s so damn cold!”

As he spoke, he first raised his hand and summoned an orange-red oak sage that was as fiery as fire and as floating as clouds, and then he grabbed Mark who was at his feet and picked him up.

Although Mark is tall and strong, the object does not seem heavy at all in his hands. He simply identifies the direction and walks towards the astronaut living module not far away.

The person who came was naturally Rosen who had just traveled through time, but he was quite unhappy.

As I guessed, the system really threw me onto this desolate Mars to keep Mark company.

Fortunately, I was prepared and alert, otherwise it would have been terrible.

Rosen complained in his heart as he moved forward in the strong wind and sandstorm.
