There are no alien bases rumored on the Internet, and there are no ancient ruins. There are just solid ground and some rocks on the moon.

But Han Xu never believed that the result would be like this. The interruption of the signal, the heat of the amulet, and the illness of the team members all showed that this place was unusual!

But right now, there is really nothing here. It’s hard to believe that after nearly seven years of preparation, we finally successfully landed on the moon, but this is the result.

This made Han Xu and Nangong Yue, who was enduring pain in the supply cabin, both fall silent.

Han Xu looked around blankly, seeming a little at a loss. Nangong Yue sent the contact information: "Come back first."

There is no way, they can't contact the Earth Command Center now, so they don't know what to do next.

Han Xu was also about to leave, but before leaving, Nangong Yue suddenly sent a message: "Think about it, how were these two ring-shaped mountains formed?"

Han Xu was stunned for a moment, and then a picture suddenly appeared in his mind. It was a gray-white satellite rotating around a blue planet. But suddenly, a huge meteorite attacked and hit it hard.

above this satellite.

The horrific impact kicked up a layer of dust, and a ring-shaped mountain range was formed. As time passed, the meteorite was covered with dust and formed a large crater.

Countless years later, another meteorite fell from the sky and hit the crater accurately. Then a second, slightly smaller crater was formed. Over time, the small meteorite was also covered with dust.<

/p>

In an instant, Han Xu figured it out. He immediately opened the tool box he carried with him and took out a shovel and a folded iron pipe. After simple assembly and connection, a small shovel appeared in Han Xu's hand.<

/p>

Then, he immediately started digging on the lunar surface.

The moon's soil has fine particles all over, probably because there is no moisture, and the dust here does not condense into thick soil.

Every time Han Xu shoveled down, it was like shoveling a shovelful of sand. This made him feel no effort, and whether it was due to the weakening of gravity or the increase in physical fitness, he felt that he had endless strength.

Compared with the weak Nangong Yue and Chu Fei, this change is really intriguing.

Nangong Yue saw that Han Xu had dug up the ground and said nothing more. He did not visit the scene in person, so it was difficult to make further judgments. During this period, he also fainted many times due to severe pain in his body. Each time, he relied on his strong will.

Wake up.

It wasn't until a few hours later that he was awakened by a crisp "dang" sound.

This may be the sound that the shovel in Han Xu's hand made after it came into contact with a hard object. The sound was transmitted along the iron pipe to the spacesuit and then to the contactor through the air in the spacesuit. The signal from the contactor was then transmitted to the supply

in the cabin, and translated into sounds for Nangong Yue to hear.

Sound cannot be transmitted in a vacuum, but if the object is always connected to the object, the sound will propagate along the object.

However, Han Xu, who was actually at the scene, didn't hear anything. He just felt the tiger's mouth tremble, as if he had dug something hard.

What Nangong Yue heard was most likely an auditory hallucination, but no matter what, at this moment, both of them showed expressions of surprise.

"I found something!"

Han Xu immediately reported the situation, and Nangong Yue nodded in surprise, but still couldn't speak with the pain in her voice. He typed and sent a message: "Come back first and bring the equipment tomorrow."

Han Xu nodded. The oxygen content in his space suit was not much, and he had already performed exceptionally well today. At this time, the oxygen content in his space suit would probably be negative.

But he didn't plan to rest, he just went back to replenish the oxygen in his spacesuit. At this time, the importance of the cableway became highlighted, because the cableway allowed Han Xu to travel back and forth faster.

Han Xu returned to the supply cabin as quickly as possible. Nangong Yue was still the same as before. Her condition did not get better, but it did not get worse. Chu Fei woke up several times during this period, and then fell into a coma again.

Han Xu fed them water and food, and then started eating and drinking water himself.

"I made a huge breakthrough today. I should have unearthed a hard object. I don't know if it's a meteorite or something else." Han Xu felt that he was in good spirits, and he ate a lot of food and had a good appetite.

Nangong Yue could still only communicate by typing, and he said: "I heard a sound, it should be some kind of metal, maybe, it is the creation of some kind of alien civilization. If so, then the significance of this moon landing will be extraordinary."

"Did you hear the sound?" Han Xu was confused because he didn't hear anything.

Nangong Yue nodded with difficulty.

Han Xu said puzzledly: "Sound cannot be transmitted in a vacuum."

"It's bone conduction. My hearing suddenly became very sensitive," Nangong Yue typed with difficulty, "I can hear the sound of your heart beating now."

This made Han Xu feel unbelievable. After several people came here, they seemed to think that something had changed for some mysterious reason.

Han Xu packed up his things and was about to leave immediately, but at this time, Chu Fei woke up. As soon as she woke up, she opened her mouth to express something, but her throat was cut like a knife and did not allow her to do so.

Han Xu quickly gave her the handle and pen, and then Chu Fei struggled to write 10 crooked words on the paper:

Microscope for extracting cells and observing them

Chu Fei coughed hard. Her body was in urgent need of water, but the first thing she thought of was to extract her own cells for observation. At this moment, she seriously suspected that the bodies of the three people had been invaded by unknown entities.

Han Xu suddenly realized it, and he also reacted. Fortunately, he had learned some basic chemical experiment knowledge.

Han Xu immediately opened Chu Fei's toolbox and found cotton swabs and test tubes. He then used cotton swabs to extract oral mucosa from the mouths of Nangong Yue, Chu Fei and himself.

Then, the oral mucosa of three people was placed on the thin film and sent to an electron microscope for observation.

The powerful microscopic power of the electron microscope allowed Han Xu to see the nuclei, mitochondria and other tissues of mucosal cells. During more careful observation, Han Xu found that there were some tiny black spots in these cells.

These black spots are distributed inside the cells, especially around the mitochondria. What surprised Han Xu was that these black spots were moving in an orderly manner, which seemed to promote the cells' ability to absorb nutrients and release them.

At first, Han Xu thought it was some kind of virus, but these black spots did not invade the nucleus or destroy the cells. They only invaded the mitochondria and reproduced themselves.

It was hard for Han Xu to believe what happened to his cells in the microscopic world, but at least to himself, this change seemed to have only benefits and no harm.
