Chapter 668: The Cave Entrance Disappeared
When it comes to going to the black hole, Xu You felt a little nervous. After all, even Xu You himself was full of unknowns about the situation inside.
Lu Zhiyao's mood was at its lowest point, and she no longer felt the relaxed mood she had during her "space travel".
In fact, these days, Lu Zhiyao has been hiding her worries and trying hard to create a relaxed atmosphere.
Going to the moon is inherently risky, not to mention the black holes under the moon.
So far, no one dares to be sure what is hidden inside the moon, and Xu You wants to go in and explore alone. How can Lu Zhiyao not worry?
However, Lu Zhiyao also knew that she could not change anything, or even help Xu You. The most she could do was to accompany Xu You outside and pray silently for his safety.
After everyone was ready, they boarded the Golden Rabbit No. 1 lunar rover and drove towards the black hole.
Along the way, Xu You chatted with everyone from time to time, but Lu Zhiyao was not as talkative and cheerful as before, and became much more dull.
At this point, Lu Zhiyao no longer had the strength to hide her worry.
Xu You noticed Lu Zhiyao's look, and still tried to find various topics from time to time so that the atmosphere on the road would not seem too depressing.
Before I knew it, three hours had passed.
Xu You and others finally arrived at the black hole on the back of the moon , this horrible place that once absorbed and crushed countless substances.
Several people parked the lunar rover and made final preparations for going down.
"In a while, the Mole will lead the way, and Academician Xu can just follow it. Half an hour later, no matter what happens, Academician Xu, you must come up."
With the amount of oxygen carried in the space suit, it is actually possible to sustain for a longer time. However, because there are too many unknown things inside the moon, staying there for too long blindly would be dangerous.
"Okay, I got it. I will watch the time and will definitely return the same way within half an hour." Xu You said.
After making the final preparations, Xu You came to the entrance of the black hole.
At this moment, Lu Zhiyao suddenly trotted over.
"I'll wait here for you to come back."
Even though Lu Zhiyao had thousands of words in her heart, in the end it was only condensed into this one sentence.
"Okay, wait till I come back!"
After hugging Lu Zhiyao through the space suit, Xu You walked towards the black hole without looking back.
Lu Zhiyao just watched Xu You disappear from her sight little by little, tears welling up in her eyes.
Xu You moved down little by little relying on the ropes lowered by the astronauts from outside the cave.
Xu You's upper limb strength is very strong. Although he is wearing a space suit, the gravity on the moon is much lower than that on the blue planet. This makes Xu You not feel very tired.
With the guidance of the Mole in front, Xu You's diving process was very smooth.
Not long after, Xu You reached the bottom of the black hole and continued to explore forward.
The road became much smoother after that, and no ropes or other aids were needed.
This space suit, which Xu You specially prepared for diving missions, not only has the high strength and high radiation isolation capabilities of ordinary space suits, but is also lighter and has a strong friction on the surface.
Even if you accidentally fall on a slope, you can quickly slow down and regain your balance.
"Next, we will soon reach the area where electromagnetic waves appear."
While reporting to his superiors that he was safe, Xu You continued to move forward carefully.
"Um?"
At this moment, Xu You raised his eyebrows, as if he had discovered something.
Xu You has been paying attention to the data detected by the space suit, and now he finally saw a change in the data.
The electromagnetic waves emitted from the interior of the moon finally appeared.
Immediately, Xu You felt that there were very subtle changes in his brain.
This kind of change is very difficult to detect, and only people with extremely sensitive senses like Xu You can feel it keenly.
"My brain waves...are amplified by some force. This is the process of brain power detection!"
At this time, Xu You wanted to contact his superiors immediately and inform them of his latest situation.
At this moment, Xu You suddenly felt that the ground beneath his feet seemed to be shaking slightly...
…
At this moment, the few people standing outside the black hole were so shocked by what had just happened that they didn't know what to do.
Just now, a powerful force suddenly surged out of the black hole, and almost instantly, the entrance of the black hole was completely sealed.
It happened at such a fast speed that no one could even react, and no one knew how such an operation could happen.
Including the rope connected to the black hole, it was immediately cut off by this force.
"This rope is made of the most advanced materials. Even the sharpest knife can't cut it easily... What kind of power is this!"
An astronaut looked at the broken mark on the rope and said in disbelief.
"Haven't you contacted Xu You yet?" Lu Zhiyao asked anxiously.
"Not yet. Because the cave entrance was suddenly closed just now, we have lost all signal contact with everything below. Teacher Lu , don't worry too much. We will keep trying to contact Academician Xu."
The astronauts tried hard to remain calm, constantly operating the communication equipment and searching for various electromagnetic wave signals below.
However, the closure of the hole created a very strong electromagnetic wave shielding effect, making it impossible for them to get in touch with the people below.
The closed part of the black hole's entrance fits in very well with the surrounding environment. If everyone hadn't been here for a long time, they wouldn't even believe that there is a mysterious cave inside.
"If Academician Xu doesn't come back, how are we going to explain this to our superiors?"
Although this is an outcome that everyone could foresee, when something like this really happens, no one knows how to deal with it.
At this time, they did not think about why this situation occurred, but were more worried about Xu You.
"Xu You...you must come back safely."
Lu Zhiyao's heart was already extremely troubled, but faced with such a situation, Lu Zhiyao had no other choice but to concentrate her energy on her brain, constantly searching whether Xu You had sent any brain waves to her.
But such behavior was undoubtedly futile. After blocking all electromagnetic waves, Lu Zhiyao did not gain anything.
