Shen Lingwei is just a small character, Luo Xu quickly abandoned it, and the robot dog's plan to explore aliens on Mars made a breakthrough, and at 18 kilometers away from the light film, the robot dog discovered an artificially built base not far from the Alcia Mountains.

Judging from the construction style and the English above, it is confirmed that it is a Mars exploration frontier base built by NASA in the United States, so Luo Xu also confirmed that the time of Mars is at least after 2020.

Did those aliens come out of this base?

Speculation is finally speculation, Luo Xu suppressed his curiosity, and began to be busy with the transformation process of X1, the first version of X1 is adapted to the Earth's atmosphere, but it is not used to explore the usefulness of alien planets, so if you want to wear this armor on Mars, it is bound to need to update the functional module and improve the parts, he was busy working for a day and a night before upgrading X1 to X2.

The shape of the X2 is not much different from the X1, Luo Xu is too lazy to redesign, he mainly focuses on the transformation to adapt to the low-pressure vacuum environment, and the upgrade of the circulatory life system, after the transformation of these two aspects, it can be regarded as an exoskeleton armor that can adapt to the complex environment of Mars.

The oxygen content on Mars is 200 times lower than that of Earth, the average temperature is minus 53 °, and the air pressure is only one percent of that of Earth. Therefore, any kind of exploration of outer space and alien planets is not a simple matter, and it can even be said that it is not only time-consuming but also takes huge risks.

Luo Xu was still a little frightened when he entered the light film in X2, and when he saw the orange surface of Mars, he was relieved that he didn't hear the warning.

According to Luo Xu's order, Bob has established a temporary base on Mars not far from the light film, the snow-white architectural style is very conspicuous in an environment like Mars, Luo Xu looked at it, and walked towards the base. Mars' gravitational acceleration is about 3.72 m/s^2, and its gravitational pull is 0.3804 times that of Earth. However, the weight of the X2 is already amazing, its actions are all assisted by hydraulics and on-board computers, through different sensors, the power exoskeleton will judge Luo Xu's intentions, so that the motors and hydraulics inside the armor assist his movements, so there is not much difference between being on Earth and being on Mars, Luo Xu didn't even feel the gravitational difference, and came to the temporary base in a few steps.

Since it is a temporary base, and it has not been built for a long time, it must not be very large in size, and it is divided into two floors in total. The first level is divided into several areas where various measuring, cooling, heating, and farming equipment are placed, as well as some spare survival resources. The second floor is the temporary living area, which can ensure that Luo Xu can rest and replenish energy for a short time.

The temporary base is also equipped with an 11-kilogram nuclear fusion cell (NFC), which can output 1,050 kilowatts of power for up to 15 years, which is enough to ensure an uninterrupted supply of energy for a small temporary base.

Luo Xu climbed into the first layer of the base, the area of the first layer is also more than 20 square meters, in order to avoid trouble, although the air pressure here has been pressurized, but it has not gone through the process of disinfection, Luo Xu still can't take off X2.

"Well, there's water in the soil of Mars."

Luo Xu had heard of speculation that there might be water in the Martian soil, but now after experiments, when the soil randomly sampled on the surface was heated to 450 °C, it was found that it accounted for 1% of the mass. This result is indeed a bit surprising, considering that the surface soil is the driest and can find so much water, then it is conceivable that the moisture in the ground or in some places must be even more amazing.

"The nutrients in the soil are also good."

Luo Xu looked off and saw the report of the soil analyzer, the average content of phosphorus was 0.30%, potassium was 0.08%, calcium was 4.10%, magnesium was 3.60%, and nitrogen was 0.12%......

To a certain extent, most of the plant soil in the Martian soil is more nutritious than the Earth, which can't help but remind Luo Xu of other aspects, if you need to colonize Mars, this is very important, at least you don't need to worry about the nutrients of the soil.

After reading a series of reports, Luo Xu planned to go directly to the discovered NASA base, he vaguely felt that the alien monster was only afraid that it had a lot to do with this base, and judging from the information sent back by the robot dog now, there were very big suspicions.

The base had apparently been abandoned for a long time, and the annual winds and sand from Mars had buried almost a third of the entire base, but no one had come to clean it up. This is not possible for a base with a permanent staff, unless something happens that causes the base to be abandoned.

"I wonder if there are other bases on Mars, and if there are any human beings?"

With this question in mind, Luo Xu sat on the Mars Explorer, which Bob built using information obtained from the NSAS site, which is an eight-wheeled vehicle, 14 meters long and 3.4 meters wide, and each wheel is driven by a reading motor, ensuring that even if one of the wheel drives fails, the Mars explorer can continue to move forward.

It has a hermetically sealed structure, and the armor is designed with a life cycle system and thermostatic equipment, which can also provide personnel with a week's oxygen reserve under the harshest conditions. In order to reduce the weight of the equipment, Luo Xu gave up the quantum computer and quantum communication equipment that required ultra-low temperature, and instead adopted the original design of NASA, and got a high-gain antenna and a low-gain antenna on the top of the car to transmit data signals.

Weapons will definitely not relax, with four K500 and ten robot dogs following behind, plus equipped with a variety of heavy weapons, this Martian explorer is by no means as harmless as it seems, even if it encounters an alien again, Luo Xu will let those monsters see what the pain of death is.

The car started silently, and the tires instantly crushed the sand on the ground that was as hard as salt, leaving two deep tire marks on the rusty red ground.

Luo Xu sat in the driver's seat, and through the polarized glass, he could see that the sky was covered with a layer of yellow sand, and the ground in the distance was full of uneven rocks, and everywhere he could see, there was sand and gravel composed of various colors such as red, black, and brown, which paved the surface of Mars with a strange color. Such a scene is rare to see on earth, or not at all, and although the scenery is a little beautiful, it gives people a vague sense of uneasiness.

Luo Xu thought about it and understood where this uneasy feeling came from, walking alone on a strange planet, facing the unknown environment would definitely produce a trace of uneasiness and fear. This is still the result of Luo Xu's scientific literacy and surname beyond ordinary people, if an ordinary person gets the light film, he must be obsessed with reselling in the two places to make money, how can he be nervous and risk running to Mars to play. Ordinary people don't have the curiosity like him, nor the courage of him, let alone his neural circuits, so it's strange if you really want to throw ordinary people alone on Mars, so that you don't turn pale with fright.

"Hey, it's a pity that there are no like-minded comrades."

Luo Xu sighed and shook his head, knowing very well that his surname would never share this secret with others, he was very aware of human greed, which had absolutely no limits and frugalities. Take himself as an example, sometimes even he will be afraid, and he will feel afraid of the lower limit, without the moral limit, without the legal constraints, and with a large amount of interests at his fingertips, what will a person do? This answer does not need to be said.

The speed of the explorer is not slow, and it can move at a speed of 20 kilometers per hour on the surface of Mars, which is smaller than the Earth, and the distant horizon really feels like it can be reached in a flash. But even this speed could not stop the night from falling, the sky gradually became dark, all kinds of hills were pulled down by the sun long shadows, a gust of wind blew, soft dust and sand particles floated on the ground, and the explorers advanced against the wind and sand of the setting sun.

When the sun set over the horizon, after more than an hour of arduous trekking, the Martian explorer finally arrived at this unknown base with Luo Xu.

The base is built against a mountain cliff to resist the attack of the wind and sand from the north, and there are about twenty large and small buildings, all of which are connected by narrow corridors, which can reduce the need to go out. Luo Xu looked at the scale of the building, and estimated that there was a construction area of about 10,000 square meters, which was a remarkable achievement, and it was impossible to build such a huge base so far away from the earth.

Luo Xu used to think that the history of the base was at least from 2020 onwards, but now that he saw it with his own eyes, he felt that he had to at least move this time back to after 2040. It is this time period that Luo Xu speculated based on the scientific and technological level of the No. 17 base, otherwise China plans to carry out a Mars landing plan in 2030, and the United States can build a large base in 2040? 2060 is about the same.

However, the development of science and technology is beyond people's imagination, and Luo Xu has a lot of insights in the No. 17 base, although the United States in 2053 lags behind China in terms of economic aggregate, but in some cutting-edge science and technology and military technology, China still needs to work hard to catch up. But the most important thing is not this, the important thing is that 40 years later, at least the scientific and technological achievements of the United States secretly will definitely exceed the imagination of mankind in 2013, and it is not impossible to colonize Mars and build a permanent base for hundreds of people.

Luo Xu wasn't sure if this was the result of a parallel world, but he didn't dare to completely deny that the real world couldn't do it. If that world is not a parallel world but a future world, technology will inevitably reach that stage in 2053.

There are too many doubts about these things, and there is no evidence that that world is a parallel world, at least from the history that Luo Xu has looked through, it is no different from the real world in which he lives. Then the possible surname of the future world is as high as 90%, which is the reason for Luo Xu's haze, if he can't find out the cause of the huge catastrophe in the future world, it means that he will face this disaster in person forty years later.

Fortunately, he still has time to deal with it, in fact, after taking the broad-spectrum gene drugs in the base and the modification of lysosomes in the body during this period of time, his physical fitness and physical fitness have been greatly improved, and he feels that his body is full of inexhaustible vitality, and his mind and spirit are becoming more and more active, and he does not feel sleepy without sleeping all night. According to Bob's inference, his lifespan has increased to about 120 years old, which is much higher than the average lifespan of all human beings, which startled Luo Xu himself.

But when I think about it, the gap between his life expectancy of 120 years and his pursuit of eternal life is like the gap between heaven and earth. (Because of the daytime work, the update will be placed in the evening as much as possible)
