Mu Mu hugged Ge Zi, pressed her to the floor, and whispered in her ear, "Shhhh ”

Ge Zi held his breath, and his hair immediately stood on end.

She heard it.

The regular beat sound, or footsteps, was above their heads, I don't know when it sounded, maybe when Ge Zi was singing, or when the two were chatting, anyway, Ge Zi and Mu Mu didn't realize what it was, Zhao Mumu's reaction was slightly faster than Ge Zi, and she noticed that there was another person's voice when she was beating the beat.

But the voice didn't come from Xiao Zi.

Rather, on the second floor of Cassini Station.

"Bang...... Smack...... Snap ......"

It was as if someone was pacing on it, and the footsteps were clear.

Mu Mu hugged Ge Zi tightly, his body trembled slightly, Ge Zi stared at the floor, one hand hugged Mu Mu's stiff waist, and the other hand slowly stretched out to push Zhuo Zhi who was lying on the side.

"What's that sound?" Ge Zi whispered.

Zhao Mumu shook his head gently, "I don't know, I thought it was your voice at first, but I found that you didn't move, could it be that there is still a person in Cassini Station?" ”

There are only six people in Cassini Station, and all six of them are in the P3 lab at the moment, so who is that person on the second floor?

The second floor of Cassini Station has not been restored to normal work, it is still in a broken state of loss of pressure, according to common sense it is impossible for anyone to survive, Steng chose to abandon the second floor when repairing Cassini Station, this is a decision made after comprehensive consideration of various factors, because the materials and resources in their hands are not enough to repair the entire Cassini Station, and they can only close the elevator and stairs upstairs to ensure the normal operation of the first floor.

Obviously, this is a helpless move, the first floor of Cassini Station is the work area, basically a warehouse and a laboratory, it is not a good place to live, living here can only be huddled together like a refugee, the second floor is the living area, there are comfortable dormitories, kitchens, halls and bathrooms, you can eat hot meals, sleep on soft beds, you can also take a beautiful shower before going to bed, wash away the fatigue of your body, that is where people live.

It's just that it has been abandoned for 20 years, and God knows what has become of it.

Ge Zi quietly pushed Zhuo Zhi hard, she didn't dare to make too much noise, so as not to disturb the people upstairs - if it was human.

But Zhuo Zhi slept too deeply, Ge Zi couldn't push hard, and wanted to pinch him, but the shell of the sleeping bag was too hard and thick, and Ge Zi's tender fingers couldn't break the defense at all, Ge Zi was out of line, except for the two girls at the moment, the other men slept like dead pigs.

Mu Mu turned over and lay on his back beside Ge Zi, her eyes swept around with the sound, she was tracking the sound, the footsteps on the second floor were swirling, it was far away from the top of Mu Mu and Ge Zi's heads for a while, and then turned back again, it felt like lying on the bed and hearing the people upstairs walking around.

But Mumu knew very well that there was no one on the second floor.

"Are there fewer people?" Mu Mu asked in a low voice, "Has anyone gone out?" ”

"Nope." Ge Zi replied, "Brother Shi, Liu Peijia, Boss Zhuo, and Dai Yue are all here. ”

Everyone else was indeed there, Shi Teng's sleeping bag was on the opposite side of the room, next to him was Dai Yue, both of them showed their heads outside, and the thing that twisted like maggots was Liu Peijia, who got into the sleeping bag without showing his head.

"Xiao Zi Xiao Zi!" Mu Mu suddenly grabbed Ge Zi, and his tone was frightened, "If you listen carefully, there are other voices!" ”

Ge Zi stared and pricked up his ears.

In addition to the regular footsteps, there were other sounds—thin voices that penetrated the floor slabs and were hard to hear.

"What's that sound?" Ge Zi asked.

"Voice." Mu Mu said, "Listen carefully, is it the voice of a human being?" ”

Ge Zi held his breath and stared at the floor.

"Hee-hee."

"Hee-he-hee-hahaha."

Cold sweat immediately poured out, soaking through his underwear, Ge Zi heard it, and laughed...... That's laughter.

In addition to laughter, there is also the sound of self-talking:

"Perfect...... It was perfect......"

"It was perfect...... Sure enough, it was perfect......"

"The world...... Exist...... Absolutely perfect ......"

Ge Zi and Mu Mu are both creepy.

What is this sound?

Who, exactly, is talking upstairs? What is he talking about? Could it be that Cassini Station is inhabited by a madman who has been isolated from the world for twenty years? But this is Titan, which is more than a billion kilometers away from the earth, not on the earth, and no one can survive here alone for twenty years without the earth's supply.

Or is there a ghost hovering in Cassini Station, the ghost of the crew who was killed twenty years ago, roaming here and refusing to leave?

Ge Zi quietly got up, she was going to call someone.

Liu Peijia is wrapped in a sleeping bag like a silkworm chrysalis, he always likes to pull the zipper to the top when he sleeps, and then wraps himself in the sleeping bag and sleeps with his head, this is to prevent disturbing the people, Liu Peijia snores like thunder when he sleeps, he can't sleep when he falls asleep, in order to avoid being smothered by his angry roommate with a pillow in his sleep, Liu Peijia chooses to close himself and isolate himself from the world like a cocoon.

Ge Zi unzipped Liu Peijia's sleeping bag, and the sound of a pig snoring immediately sounded.

Mu Mu looked sideways and was startled.

Ge Zi gently shook Liu Peijia and patted his cheek, "Get up!" Get up! Hurry up! ”

Liu Peijia was very unhappy with the person who disturbed his sleep in his sleep, he knocked off Ge Zi's hand, then turned over and continued to sleep.

"Get up, Liu Peijia, something happened!" Ge Zi lowered his body and whispered in his ear.

Liu Peijia was indifferent.

"Earthquake, tsunami, volcano eruption!"

"The world is ruined!"

"The rescue team has arrived!"

"Your wife is coming for you!"

"Which wife......" Liu Peijia said in his sleep.

"The one in Tongzhou, Beijing!"

"Let's ...... Let her go back and say I forgive her......" Liu Peijia said.

"Guangzhou Baiyun one!"

"That...... I also forgive ......"

Seeing that he couldn't wake up, Ge Zi had to reach out and pinch his nose and mouth.

The effect of pinching his nose and suffocating was immediate, and in less than five seconds, Liu Peiqi was awakened, his big face was flushed, he opened his eyes angrily and was about to curse, Ge Zi hurriedly covered his mouth.

"Shhhh

Liu Peijia was stunned for a moment, and turned his head to see Mu Mu looking up at the ceiling, his face solemn and frightened.

"What's wrong? What the hell are you guys doing? ”

Liu Peijia got up very angry.

"Don't talk, listen." Ge Zi pointed to the top of his head.

Liu Peijia raised his head, and after a few seconds, he heard crisp footsteps from the ceiling above his head, as well as weird laughter.

"Hee-hee."
