On the barren maroon land, the crawler was still walking slowly in front, and a few meters away was a faintly flowing silvery ellipsoid.

After spending more than half an hour following Zhu Rong, Lu Yu already felt a little bored.

glanced at the mobile phone screen sandwiched above his head, there were still more than 300 people left in the live broadcast room, and after a long period of silence, most of the melon-eating audience had already run away.

But Lu Yu really didn't dare to close this live broadcast room at will, for fear that after it was closed, he would completely lose contact with Blue Star.

"I should have brought more food if I knew I should have done so......"

Lu Yu took out a large plastic bag from the side of the seat, which contained some snacks, biscuits and a few bottles of mineral water, which he bought to show the excellent carrying capacity of the [Silver Star], who would know that it had become his life-saving food.

It's just that even if you save food and drink, you won't be able to last a week and it will be consumed.

"If I'm not mistaken, in 'The Martian', it takes more than a year to prepare for Bluestar's rescue at the earliest, right?"

"Hmm...... Isn't that dead? Even Jesus was beyond the service area and could not be saved. ”

"Can we only hope for a system that teleports itself to Mars and goes to sleep?"

Lu Yu looked at the monotonous Martian environment outside, and felt that if he had a base, would he be able to try to grow potatoes.

Such a fantasy was quickly pulled back to reality by hunger, and Lu Yu looked at the Zhurong who was stunned and continued to move forward, and finally stopped following in frustration.

"What if you follow it all the time?"

"It's better to fill your stomach first, and then wait for that inexplicable system to wake up, and then see what to do."

Thinking like this, Lu Yu opened a biscuit, took mineral water, and simply ate the first lunch of humans on an extraterrestrial planet.

Miraculously, the Zhurong actually stopped not far away, directly stopped camouflaging, and turned the camera to look at the location where the [Silver Star] stayed.

However, Lu Yu didn't have the extra energy to observe this, and after eating half full, the blood began to concentrate in the digestive organs, and the subtle feeling of fatigue eroded the brain.

Lu Yu, who had been busy with his work for the past few days, had been accumulating tiredness like a burst of brain, and he simply leaned back on the soft chair and fell asleep.

I don't know how long it took, consciousness returned, and Lu Yu found himself standing in a white vastness.

Somewhat dazed, he looked around, and soon noticed a light blue light curtain floating in front of him, on which lines of text were displayed in Chinese.

Black technology embodiment system:

This system is committed to improving the level of the civilization where the host is located, and the host can get points rewards by improving the science and technology of the civilization by any means, so as to exchange for all imaginable black technology products.

The main page of the system is described as follows.

Upgrade the planetary-level tech tree and reward 1-99 points according to the degree of contribution.

Upgrade the Stellar Tech Tree and reward 100-999 points according to the degree of contribution.

Improve the river-level technology tree, and reward 1000-9999 points according to the degree of contribution. (Note 1)

Improve the cosmic technology tree, and reward 10,000-99,999 points according to the degree of contribution.

There is no measurement standard for a law-level technology tree.

----------

【Points Usage Criteria】

S-class does not have the right to redeem it for the time being.

10,000-99,999 points can be exchanged for A-level black technology products.

1000-9999 points can be exchanged for B-level black technology products.

100-999 points can be exchanged for C-level black technology products.

1-99 points can be exchanged for D-level black technology products.

The system can customize and generate black technology products according to the host settings or requirements.

…………

The light curtain in front of him is clear and monotonous, Lu Yu, who has learned some information, doesn't know what to do, not long ago he was just a college student who was worried about employment, and wanted him to improve the human technology tree, isn't this system a little too strong?

What makes him even more powerless to complain is still to come.

As soon as the caption vanished, his properties panel reappeared.

Host: Lu Yu

Credits: 0

Mission: None

Currently has black technology products: S-class [Silver Star] single-person space jumping machine (generated according to host settings)

Seeing the items he owned on the attribute panel, Lu Yu suddenly felt that he had an extra piece of knowledge in his mind that had just been stuffed in, and he suddenly understood all the ways to use the [Silver Star].

All the configurations of this single-person space jumping machine, how to drive it, Lu Yu understood it when he saw the attribute panel, and he understood it so simply, as if he had mastered a detailed instruction book in an instant.

It can only be said that the more high-end black technology is, the simplest learning method is often needed.

Just as Lu Yu was still reminiscing about this feeling of sudden realization, the white space gradually faded, and gradually everything outside began to become clear.

In the blink of an eye, Lu Yu found himself back in the cramped cockpit.

I didn't look at my phone, but I looked out at the Mars through the cockpit, and it was already dark.

Lu Yu thought back to the setting of this black technology, and actually tried to slowly push open the hatch, revealing a small gap.

There were no leaks, nothing out of the ordinary, and a faint film of light lit up in the gap in the hatch.

Lu Yu pushed it even more boldly, the hatch was ajar, and the translucent white light film formed an arc-shaped light mask between the hatch and the exit, blocking the air leakage in the cabin and all intrusions from the outside world.

This layer of light film is one of the four layers of protective armor that Lu Yu said in the live broadcast before, in Lu Yu's cognition explanation, it belongs to a kind of space armor, which can sense Lu Yu's brain waves, and only after his consent can the inside and outside be connected.

Without Lu Yu's certification, even the four fundamental forces would not be able to affect the cockpit from the outside.

Lu Yu directly tried to let the light from the outside world in his consciousness, and the light film gradually became transparent, and the dim Martian dusk appeared in front of his eyes.

He admired the alien twilight, picked up a bottle of mineral water, and just wanted to replenish some water, when suddenly a wonderful idea came to his mind.

From the pile of bottles that Lu Yu turned around, he found a clean mineral water bottle, poured a quarter of the water into it, slowly squeezed out the air inside, and then tightened the cap.

Then I found a piece of wire, wrapped it around the mouth of the bottle twice, and then stretched the bottle out of the light film.

The low air pressure on Mars caused the remaining air in the bottle to expand a little quickly, and the low temperature after dusk caused the pure water in the bottle to freeze rapidly.

At this time, Lu Yu pulled the bottle back again, and the clattering bottle deflated again, and the water inside had turned into ice.

The air in the [Silver Star] cabin is generated according to the proportion of the air of the Blue Star, and the air of the Blue Star contains water!

Lu Yu placed this bottle into a larger severed bottle, and after a while, he saw small droplets of water condensed on the frozen bottle, which soon caused water marks to gather at the bottom of the large bottle.

Water condenses when it meets it, and it can't be simpler than physical common sense.

As long as the Martian environment and the air composition in the cockpit are stuck in this way, Lu Yu's water source will not be a problem!

Food and water, two major survival problems seem to be solved at once!

Lu Yu looked at the shallow layer of water that had condensed at the bottom of the big bottle, but he couldn't help but smile bitterly.

Sitting in a space-jumping machine with technology that is many years higher than that of humans, but relying on this simplest method to collect water?

What's even more troublesome is that Lu Yu confirmed a terrible fact from the situation he recognized.

There is no navigation on this [Silver Star],...... Because Lu Yu didn't mention this setting at all when he was hi, and this is the most deadly.

The position of the entire solar system in the universe is not determined by human beings, and it is the cantilever of the Milky Way.

If you want to jump back to the blue star, you must have precise coordinates and a navigation system.

But during the live broadcast, Lu Yu only thought about the whole job, where would he have thought that he really made a space jumping machine?

Now if you activate the space jump, Lu Yu will randomly teleport to any location in the universe!

RNM, return!

Lu Yu, who understood that it was difficult to rely on space to jump back to the blue star, couldn't help but scold the system fiercely in his heart, but after all, it was just incompetent and angry.

But I just had an idea and thought of a solution to the water source.

As for the issue of food, it can only be taken one step at a time.

Thinking of using the collection of water to suppress the sense of loss, Lu Yu untied the wire of the bottle that was melting ice, and found a clean mineral water bottle to prepare to copy a wave of operations.

He just wanted to stuff the bottle out, but the situation outside made Lu Yu stunned.

Zhu Rong turned to the side of the hatch in the dim at some point, like an ugly moth, fluttering on the solar panels on both sides, just to attract Lu Yu's attention.
