Reborn Before the Apocalypse: My Backing is the Nation

Chapter 93 Gravity
In that lifetime, nine astronauts entered this cave and never came out again.

Jiang Yang knew that in this life, all 13 of his astronauts would repeat the fate of the astronauts in the previous life, and would also perish in this cave.

The only difference is that the secrets of this cave will be carried into the next life through its own time looping ability, providing guidance for people in the next life.

Death was inevitable, but this death will surely be worthwhile.

In complete silence, the 13 people moved forward slowly.

Although people knew that there was likely no danger in the first 4000 meters, they still remained quite cautious in their actions during this phase.

Jiang Yang also took this time to carefully observe the situation of the cave.

He observed that, apart from some moon dust accumulation at the cave entrance, the interior of the cave was perfectly smooth and flat. The cave walls were even, and the ground was free of dust.

Just like this cave is regularly maintained and cared for.

Of course, this is not necessarily the case.

Cleanliness and tidiness do not necessarily mean that anyone has been here. Because this is the moon, a vacuum environment. Even landforms from hundreds of millions of years ago can be well preserved to this day.

People moved forward slowly along the gently sloping hillside.

500 meters, 1000 meters, 1500 meters...

It continued until the mechanical rangefinder showed a distance of 4000 meters.

The cave is still the same cave. Whether at the entrance or at a depth of 4000 meters, it remains unchanged, still square and neat.

But every astronaut knows that his nine comrades from that previous life "disappeared" after crossing this distance.

If there is danger, we will encounter it after crossing this distance. And, most likely, we will perish there.

At this moment, even Jiang Yang, who had experienced death many times, couldn't help but break out in a cold sweat.

That was an instinctive fear of the unknown, and even if Jiang Yang experienced it ten thousand times, he could never completely eliminate it.

And... even I can't help but feel fear, so what about the astronauts?

Jiang Yang looked to his left and right and saw Tong Zheng, who was marked with the number 1 on his body, stretching out his arm straight forward.

That means to keep moving forward.

The column continued to advance in silence, without the slightest hesitation, only slowing down a little, and their nerves were on edge.

Suppressing his unease, Jiang Yang followed the group slowly, while trying his best to observe the surroundings and any abnormalities that might occur on himself.

In a daze, whether it was an illusion or something else, Jiang Yang suddenly felt that his bulky mechanical spacesuit seemed a little lighter.

Upon closer inspection, he was horrified to realize that this was not his imagination, but rather that the lightness was indeed a little too great!
The astronauts continued moving forward in silence, seemingly oblivious to what was happening.

Perhaps their physical abilities are too high and their load-bearing capacity too strong, which is why they are completely unaware of such a slight change in weight.

But I am different!
At heart, I am just an ordinary person. Perhaps that is why I am able to perceive this.

He instinctively shouted, "Something's wrong!"

But the astronauts remained unmoved.

After a pause, Jiang Yang realized what was happening and immediately tugged at the astronaut standing beside him, protecting him closely. Then, he raised both arms at the same time and waved quickly.

The astronaut immediately turned around and notified the other astronaut beside him. In this relay, within half a minute, everyone stopped and gathered in front of Jiang Yang.

After opening the cover on the left arm, Jiang Yang quickly wrote some symbols and words.

"I feel like my spacesuit is lighter, what about you?" Although he couldn't see the astronauts' faces clearly, Jiang Yang could still sense the solemnity in their expressions.

They began to carefully perceive it. After a moment, some astronauts drew a checkmark on the drawing board, while others waved their hands, indicating that they did not feel anything.

Of the 12 people, 10 realized this after Jiang Yang reminded them, and only two did not!

Jiang Yang erased the previous writing and quickly wrote: "Gravity?"

He suspected that the moon's gravity had changed at his current location! Otherwise, how could the weight of a spacesuit with a fixed mass change?
After a brief pause, astronaut Tong Zheng casually pulled a bullet from his waist, raised his arm, and then let go.

The bullet fell downwards at a speed significantly slower than that of Earth, and after a few moments it hit the ground, bounced a few times, rolled deeper into the passage, and disappeared in the blink of an eye.

Tong Zheng waved his hand.

The magnitude of gravity can be measured using gravitational acceleration. Previous tests confirmed that the bullet's downward acceleration remains approximately 1.6 meters per second squared. This means that the gravity in the environment has not changed at this moment!
But, since gravity hasn't changed, why...?

call……

Jiang Yang let out a soft breath, making sure to remember this unusual detail.

Let Professor Lu Zhaoming analyze it in the next life.

Astronaut Tong Zheng extended his arm again, signaling to continue forward.

Discovering this anomaly alone is not enough; we must continue to explore the mysteries of this cave and its underground chambers.

People are moving forward more slowly and are more tense.

As the spacesuit grew lighter and lighter, Jiang Yang suddenly saw something pop out from the back of Tong Zheng's spacesuit.

Because it stayed in the air longer and its flight speed was not fast, Jiang Yang was able to get a clear look at its appearance.

That looks like a small spring?

Ok?
The next moment, a white mist shot out from the spring-loaded part of Tong Zheng's spacesuit back, drifting and scattering, turning into ice crystals in mid-air and falling down like snowflakes.

Gas leak!

Those ice crystals are formed by the sublimation of water vapor in the gas!

Jiang Yang wasn't the only one who witnessed this. At that moment, several astronauts acted simultaneously: one took out tape and quickly sealed the leak, another pulled Tong Zheng back, and a third quickly drew a circle on a drawing board and then used a straight line to pierce through one side of the circle.

A moment later, he erased the image and drew only a circle.

This means the leak has been eliminated.

Tong Zheng gave an OK sign, and then stretched his arm forward again.

But at that moment, Jiang Yang was somewhat horrified to see that white mist appeared on the bodies of the other astronauts at the same time, and a piece of steel plate on the back of one astronaut's spacesuit fell off.

Steel plate?

Jiang Yang subconsciously bent down to pick it up and saw that the steel plate was extremely thin, so thin that it could only be called sheet metal, not steel plate.

But he clearly remembered that the back of his spacesuit was made of steel, not sheet metal...

In an instant, a thought suddenly popped into Jiang Yang's mind.

Holy crap, is this spacesuit lighter because it's thinner?
