"It is about to pass through the Martian atmosphere and reduce the altitude of the orbit. Thrust reverser has been turned on. Stow the solar sails. Fuel remaining: 53%. ”

"It has passed through the Martian atmosphere, the powerful thrusters have been activated, the spacecraft is hovering and ready, and the expected landing site is 21km away from the setting."

"Hovered landing. Outside temperature: -34°C. External atmospheric pressure: 7 mbar. ”

Opening his eyes from the sleep pod again, Ruan Lin heard the landing announcement of WIT. At this time, 102 hours have passed since the Earth's tear was observed.

The next step is to collect all the materials that are urgently needed on the far side of Mars, according to the plan.

Mars is just a transit point for Ruan Lin, and the fuel issue is a constant reminder that Ruan Lin needs to find a new way to use energy - controlled nuclear fusion.

Ruan Lin, who has inherited all the knowledge, can naturally avoid many detours. Ruan Lin still decided to use the 'magnetic confinement fusion', which has been studied for the longest time and has the greatest probability of success.

Geoscientists have been on the path of controlled fusion research for nearly a century.

Magnetic confinement fusion refers to the use of a special form of magnetic field to confine the ultra-high temperature plasma in a thermonuclear reaction state composed of light atomic nuclei such as deuterium and tritium and free electrons in a limited volume, so that a large number of atomic nuclei fusion reactions can occur in a controlled manner and release energy.

If fusion research is not completed soon, subsequent refueling of nuclear reactors will be a headache.

Although the current fuel can barely reach a suitable planet, mining and refining spaceship fuel. But the solar system has become extremely unstable. And it's always a waste of time on refueling, and nothing else can be studied.

"Let's go through the steps step by step first. WIT, send a couple of Mars rovers out there, and we urgently need to find a suitable piece of medium-mafic rock to mine uranium ore and refine uranium-235.

Fuel supply is a top priority right now, as well as the power of our spacecraft, which all rely on nuclear energy. ”

"Maybe we should build another ship, we also need to build a robot assembly line inside our current ship, and we need more helpers to solve some minor problems." Ruan Lin gushed endlessly, expressing his plan sentence after sentence.

"Okay, Dr. Nguyen, I'll do the rover in ten seconds, and we'll collect enough material from here for our next voyage.

Leave the small assembly line to me, and I have a special digging and survey robot for Mars in my database. With that, WIT began sending commands to the ship's central host. Everything is going on in an orderly manner.

Maybe it's time for me to give up my flesh too? Upload my personal consciousness directly to a central host computer for digital immortality.

I could build another small supercomputer on a spaceship, and then I could rely on the computing power of the computer to reach 339 million quellaps per second, and WIT and I could complement each other.

Ruan Lin waved his hand: "Maybe this is the most suitable method for me, if I am the only human race in the whole universe, I must first ensure my safety, my physical body is still too fragile." ”

"Dr. Ruan, it's been 10 minutes since the rover was sent, and we've found a gravity anomaly not far from the spacecraft.

The quartz spring gravimeter of one of the large mining rovers was preliminarily judged to be a dense ore area on Mars, which is a rare mineral on Mars, but it is common on Earth. "WIT has good news at this time.

Ruan Lin said excitedly: "After laying a small production line, we will speed up the production and assembly of robots and survey vehicles!" We have to exploit the resources we need at all! ”

"We found an anomalous gravitational value, and at my marker, the gravitational acceleration on the surface of Mars is 9.82 m/s^2."

The gravity ratio of Mars to Earth in this area is the same. It is 7km away from the spacecraft in a straight line. WIT opens the central screen, and the red dots on the map are marked with frequencies of flashes.

Ruan Lin was stunned for a moment, and couldn't believe the WIT report: "The gravitational acceleration of this piece is actually the same as that of the earth?" How could it be such a coincidence? That's ridiculous.

No matter how different the gravity measured by the gravimeter is, it is impossible for Mars to be consistent with Earth. The gravitational formula is about to be overturned? Joke! We'll have to do another surface survey of the area, and once the mining robots are assembled, we'll have to dig to figure out what's going on! ”

"As you wish, at this point in time, the first survey robot has been assembled and is on its way here." WIT reports on its work.

Maybe I should try uploading my consciousness to the motherboard of this robot? Hands-on practice is the only way to achieve results more intuitively.

Ruan Lin saw through the window of the spaceship the somewhat comical survey robot—like the 'Hypertherm robot' on Earth in the past.

Ruan Lin could see through its outer body and its main brain.

"Let's get started."

Ruan Lin could feel as if his consciousness had been drained away.

In the next second, Ruan Lin opened his eyes. What he saw was not the cold decoration inside the spaceship, but the world that made Ruan Lin feel extremely amazed.

It's sunrise time on Mars, and the sky is a pale blue sky that Ruan Lin has never seen on Earth, and the sun seems to be dyed by the Martian sky, and it also shows a pale blue light.

The apparent diameter of the Sun is almost one-third that of the Earth, and one-ninth of its apparent area. From the ground, it looks like you're alone in the Sahara Desert on Earth.

It is surrounded by ravines and valleys dyed rust red. These landscapes are indistinguishable from Earth, and they look so smooth.

Perhaps many years ago, it was a valley; Everything looks like it was born alive at the beginning of life.

But nowadays. Mars, the planet known as Mars, the god of war, since ancient times. Now it seems so lifeless and hopeless.

At the same time, Ruan Lin felt free from the limitations of 'human' – no need to breathe, no need to eat. But they couldn't smell or make any sound.

He could feel his two tracks, his two robotic arms, and his 'brain' repeating logical operations. You can receive instructions from WIT, but you can do what you want.

Ruan Lin knew that he couldn't think too much and couldn't be too fast. Otherwise, his new 'brain' will not be able to afford it.

It is important to find out what is really going on as soon as possible.

Ruan Lin sped up the travel speed of the tracks.

"The target location has been reached and the second surface exploration has begun."

"The surface gravitational acceleration is 9.82 m/s^2 over a range of 5 km in this area."

"The digging robot is about to start working, start digging."

Commands from WIT are automatically translated into a language they understand.

Ruan Lin watched from the sidelines as the digging robots began to work. They resemble mini tractors, with an earthy yellow exterior and the only difference being that they carry a number of drill bits to drill through hard mines.

It is in the nature of men to worship the mechanical Force. Watching the excavator dig the ground is a man's romance!

Nguyen Lin's memories are brought back to his childhood.

Passing by the construction section, I heard the sound of the excavator working for the first time.

The heat of the motherboard's brain brought Ruan Lin back to reality.

It's time to go back.

When I opened my eyes, I was in a medical cabin.

Wit poked his head over and said, "Dr. Ruan, in the past twenty minutes, not any organ in your body has been functioning at all, and it has been preliminarily determined to be dead.

I don't understand what's going on now. Can you explain this to me? I don't see this type of event in my knowledge base. ”

"Haha, I'll explain this to you later when I have time!"

"Let's transfer my consciousness to the computer! This robot is too awkward, I don't want to be a mecha in the future. Ruan Lin muttered.

"Okay, Dr. Nguyen. The excavation continued, and the excavation robot dug up the man-made object. ”

"Artificial? There can't be anything here. Speed up the excavation and be careful not to damage the excavation! It only took a few seconds for Ruan Lin to check the crash history of various human probes and aircraft in his mind. But there are no records on Mars.

"The excavation is complete."

Two hours later, WIT rolled out the central screen. interrupted Ruan Lin's musings.

I saw that what was displayed on the screen was a man-made object that looked like a pure black spear. The widest point is about 14 meters in diameter and more than 16 meters in height.

It resembles a space-based weapon conceived by humans, and the most prominent part of it is like a sword tightly wrapped in six flying wings.

Ruan Lin was stunned, as if he had lost his voice, as if he was numb, he could neither say a word, nor control the strength of his fingers.

"This... It can't be something that humans can make. How long has it been lying here? If Mars is closest to the Earth, if a research ship is sent here, will it be possible to analyze extraterrestrial technology and avoid the tragic fate of the Earth and the Moon being broken? God is really playing tricks, why didn't you find it sooner! ”

Ruan Lin chose to compromise on his unwillingness: "That's it, what's the use of talking about this now?" wit, let's start parsing and figure out what the hell this is. ”

"Dr. Ruan, after a small part of dismantling in these few minutes, the six flying wings that wrap the outside and inside should be some kind of energy conversion device, equivalent to the solar sail we use.

The encased 'stamens' were found to have a history of direct laser light. Presumably a very accurate galaxial-level laser pointer, you're right. It's not something humans can make at the moment. ”
