Han Xu was very surprised. This pure silver amulet had been oxidized and sulfurized due to age, and it was almost impossible to tell it was a piece of silver, but now it looked brand new as if it had been washed with silver washing water.<

/p>

Han Xu immediately opened his collar, and then saw a black ring mark on his chest, which made him panic.

Isn't this black thing some harmful substance?

Han Xu immediately used his hands to buckle it, but found that it could not be buckled off at all. It was as if the black mark was deeply imprinted into his skin like a tattoo.

This incredible change caught Han Xu off guard.

But so far, Han Xu has not noticed anything wrong with his body, and as the black substance on the surface of the amulet disappears, he can clearly see what is carved on the amulet.

There is a ring mark on this amulet, and there is a strange polygonal relief in the ring. Han Xu cannot understand the meaning of this relief, but he is sure that this amulet is definitely extraordinary, and it must have something to do with the back of the moon.

Han Xu couldn't be sure, but he didn't take off the amulet, but stuffed it into his collar, and then started to sleep. Tomorrow, they would head towards the inner ring.

The next day, when Han Xu and others woke up, Nangong Yue sneezed loudly, which surprised several people.

Chu Fei looked at Nangong Yue in surprise: "Can you take your temperature and see how you are doing?"

There are only three of them on the back side of the moon at the moment. Each of them is an important main force in lunar exploration and is indispensable.

However, Nangong Yue waved her hand: "It is impossible for viruses or bacteria to survive here. If there are, then I think it is a good thing that I got sick because of it."

Han Xu nodded. In a vacuum environment, almost no living things can survive, let alone viruses and bacteria. Therefore, it is impossible for Nangong Yue to catch a cold. At most, it is because of dust...

But this is almost impossible. The supply module is a completely sterile and dust-free environment. There is no possibility of dust unless it is brought in from the lunar surface.

And if the moon shows the existence of bacteria or viruses, it will definitely be a breakthrough in biology. Even this discovery will make their trip worthwhile.

This was just a small episode. Although the three of them were nervous, it was impossible for them to stop working just because of a sneeze.

"Today is 8 a.m. on September 13, 2030. We are about to leave the supply cabin. Today's task is to build a simple ropeway on the top of two craters to save us round trip time and carry cargo."

Nangong Yue briefly said a few words in the mission log. At this time, Han Xu and the others had already put on their spacesuits. Nangong Yue nodded, but immediately left the supply cabin with the team.

Then, they brought the materials and tools to build a simple ropeway, and then set off.

When leaving the supply cabin, Han Xu looked at the sky. The shield on the helmet was ink-colored, which could effectively prevent his eyes from being burned by the sun.

When he entered the supply cabin yesterday, the sun was high in the sky. It was the same now and will be the same in the next ten days.

Because the length of day and night on the moon is twenty-seven days, there are fourteen days in one day or night.

This moon landing plan has been planned for seven years, so every detail will naturally be carefully considered. In the next ten days, they will work in the sunshine.

The three people left the supply cabin and started climbing. Because they had already had mountain climbing experience, they seemed particularly relaxed this time.

After arriving at the top of Outer Ring Mountain, they immediately began to build the A cableway station. This was not difficult because all the required materials were easily foldable. They only needed to insert the base into the ground, and the base deep into the ground would pop up four times.

Block the blade, so that the base can be fixed.

Then the solar panels are deployed for fourteen days, so that the solar energy is not used in vain.

After the A cableway station was built, the three of them began to pull the steel rope to the Inner Ring Mountain. The height of the Inner Ring Mountain was only about half of the Outer Ring Mountain. It only took them an hour to reach the top of the Inner Ring Mountain.

But the Inner Ring Mountain is completely covered by the shadow of the Outer Ring Mountain. When they come here, they all need to turn on the miniature flashlight on their helmets.

Under the illumination of flashlights, they began to build Ropeway Station B.

Han Xu took the time to take a look inside their destination - Neihuan Mountain. It was pitch dark and it was impossible to see clearly and there was no way to know what was inside.

The entire inner ring of mountains is not big, just like a volcanic crater. It is so dark inside that you will feel heart palpitations if you look at it for a few more times.

The three people built the B cableway station, installed the winch and the steel cable, and then hung up the pulley.

In this way, a simple cableway that can be used on the moon and has a moderate load capacity has been built.

Nangong Yue was the first to use it. He took out the traction rope and hung himself on the pulley. As the machine started, the pulley began to slowly move towards the outer ring mountain.

A few seconds later, Nangong Yue's feet were hanging in the air. Han Xu and Chu Fei had been watching, but there were no problems in the whole process. Nangong Yue successfully reached the top of Outer Ring Mountain.

Nangong Yue started the switch and slid the pulley back, and then Chu Fei started to use the ropeway to return to the Outer Ring Mountain.

For safety reasons, this cableway can only carry one person at a time. In an emergency, it can also be set up for three people, but it can only be used on the moon because the gravity here is low.

After Chu Fei slid over, it was Han Xu's turn. Han Xu followed suit and hung the pulley with a traction rope, and then hung it on the ropeway and floated towards the outer ring mountain.

After his feet left the ground, Han Xu felt the gravity of the moon. This gravity was really light, which made Han Xu feel like he was floating. He crossed two craters and looked at the pitch black under his feet, which felt a little strange.

feeling.

After Han Xu arrived at the top of the Outer Ring Mountain, Nangong Yue said: "It seems that the design and planning of the cableway are relatively mature. The low gravity of the moon is indeed very suitable for building such a simple cableway, which can save us a lot of time."

Han Xu nodded. He did feel like he was flying through the air just now, but when he listened to Nangong Yue's words, he heard that Nangong Yue's voice was a little hoarse, and he didn't know what was wrong.

Chu Fei looked at the time on the monitor and then said: "In 24 hours, Country M's carrier rocket will be launched. We only have one day now."

The three of them were all in a serious mood, and they immediately returned to the bottom of the mountain. But when they were going down the mountain, Han Xu noticed that the speed of Nangong Yue and Chu Fei had obviously dropped a lot, but Han Xu only thought that they were exhausted.

After all, I am much younger than them.

Han Xu just thought so, but when they came down the mountain and returned to the supply cabin, Nangong Yue suddenly started coughing. Han Xu found that his face was pale and his lips were bloodless.

Han Xu immediately asked: "Captain, what's wrong with you?"
