Ge Zi stared at the ceiling for a long time,

Unfortunately, she couldn't see through the thin floor slab overhead, and if she had infrared night vision, a life detector, or a through-the-wall perspective radar, she would be able to see what's on the second floor.

They are so close to the truth, but it is such a little distance, it is only half a minute to go up a building on earth, and it is an insurmountable moat on Titan, Ge Zi suddenly had a strange and flamboyant delusion in his heart - this is a parallel world, each layer is a different universe, different people live in different environments, and there is a thin floor between the universe and the universe, they live on this floor, they can hear the sound of the upper floor, but they can never meet their neighbors on the upper floor.

This is the closest distance, and the farthest distance, and the floor is the wall of the universe.

If Ge Zi was a creature born and raised here, how would she imagine how humans in the upper universe lived? Drinking a glass of hot methane in a low temperature of minus 180 degrees Celsius?

"Can anyone really survive here for twenty years?" Ge Zi asked softly.

"Impossible." Mu Mu sat across from her and shook his head, "Xiao Zi, what was the situation at Cassini Station when we first came, everyone knew that it was impossible for anyone to survive in this environment. ”

Before the crew of the Hades prospecting ship arrived at Cassini Station, the station's energy supply and life support systems were shut down, indicating that there was no oxygen or fresh water in the station.

"Speaking of the number of people, Boss Zhuo and I had a guess before." Dai Yue suddenly said, "Twenty years ago, there were probably more than seven people in Cassini Station. ”

The others were stunned.

"What we found when we inspected Cassini Station, we found that a set of Iron Floats was missing." Dai Yue said.

"Missing a set of Iron Floats?" Mu Mu asked.

"Yes, there's one less set of Iron Floats." Zhuo Zhi nodded, "Without Mr. Lou Qi's Iron Floating Massacre, according to the mission records we saw, twenty years ago, Lou Qi, an electronic communication technician at Cassini Station, mysteriously disappeared one day after discovering the black ball, and has not been heard from since, right?" ”

Ge Zi and Mu Mu nodded.

They were equally impressed.

No one can reasonably explain Lou Qi's sudden disappearance.

If Hu Donghai's death was a murder, then Lou Qi's disappearance could not even find the murderer.

"Then the Iron Floating Massacre that originally belonged to Lou Qi should be an ownerless thing, stored in the tool room, until we arrive here and find it." "But obviously, we didn't find the Iron Float ......."

"Wait, wait, wait." Mu Mu interrupted him, "It's possible that Miss Moyu wore this Iron Float, Miss Moyu was seriously injured by a volcanic eruption while repairing the communication tower, and then was rescued back to Cassini Station, do you remember?" Her set of Iron Float is damaged, and she must replace it with a working ......"

"Yes, that's what we've taken into account as well." "Miss Moyu was injured while repairing the communication tower, and according to the available records, she was taken to the operating room immediately after being rescued back to Cassini Station, and the broken iron float was taken off and sent back to the tool room for repair...... Here's the problem, her set of iron floats is gone. ”

Mu Mu was stunned.

"One person can't wear two sets of Tiefutu, no matter which set Miss Mo Yu wears in the end, whether it is her own set or Lou Qi's set, then there will inevitably be one set left." Zhuo Zhi explained, "This is because after Lou Qi disappears, six people correspond to seven sets of Iron Floating Tu, and there will definitely be one set left. ”

Mu Mu frowned and began to think about what Zhuo Zhi said.

"It is reasonable to infer that there must be a set of Iron Floats that have been in the tool room all along." "That is, if nothing else, it should remain inside Cassini Station, waiting for us to discover it." ”

"Wait, Boss Zhuo, wait!" Mu Mu interrupted him, "How many sets of Iron Floating Tu are there?" ”

"Seven sets." "There are only seven sets of fixtures in the tool room. ”

"Hu Donghai took a set with him after he died." Mu Mu said.

"Yes." Zhuo Zhi and Dai Yue nodded.

"Then there are six sets left, six people." Mu Mu said slowly, "Then Lou Qi disappeared, six sets of Iron Floating Tu, five people. ”

"That's right." Dai Yue said, "We searched through all the records that followed, but we couldn't find where this set of Iron Floating Tu went. ”

"Maybe it's lost, after all, it was so chaotic." Ge Zi asked, "Is this possible?" ”

"If it's lost, there's no way to explain why the extravehicular suit fixture in the tool room is still there, but the Iron Float is gone, so I have to throw it away." Dai Yue glanced at her, "Judging from the records, the two sets of Iron Floating Tu have returned to their original positions after taking them off, and there is no reason why they will disappear inexplicably." ”

It's not really likely.

Everyone knows what the Iron Float is...... It was an extravehicular suit weighing dozens of kilograms, equipped with a powerful mechanical exoskeleton, standing there like armor, and indeed wearing it like armor, which was the source of its nickname, and the Iron Float was by no means a gadget that was easy to lose.

The clamp of the extravehicular suit is also a two-meter-high behemoth, it is a metal wardrobe, when you stuff the Tiefutu back into the clamp of the extravehicular suit, and then you want to lose it, you can only use Lu Zhishen's strength to pull out the weeping willow and carry the wardrobe and throw it out together - and this is impossible at all, because the hatch in the tool room is not so big.

Excluding the possibility of loss, then there is only one reason for the disappearance of the Iron Float.

"Someone wore it through."

Mu Mu figured it out and shivered.

Twenty years ago, on the eve of the destruction of Cassini Station, an eighth man watched the demise of mankind with a cold eye.

He wore the last set of Iron Floats.

"Mu Mu, did he kill Director Hu Donghai?" Ge Zi grabbed Mu Mu's hand hard, his face turned pale, "This person we can't see...... He put a microwave oven on Director Hu's head, killed him with this, then took off his helmet and left the scene of the murder. ”

Mu Mu and Ge Zi previously introduced the cause of Hu Donghai's death that there was a person who killed people with a gamma knife.

And Dai Yue and Zhuo Zhi launched from the number of Iron Floats, and there was still an eighth person in the Cassini station that year.

Ge Zi realized that the two parties might have found the same person-

Could this person be the murderer who killed Hu Donghai?

"So......" Dai Yue finally asked faintly, "Now, twenty years later, at this moment, how many people are there in Cassini Station?" ”

All four people in the lab had scalp tingling at the same time.

Six?

They looked upstairs.

No, seven.

Twenty years later, they once again saw the nightmare faced by the Cassini station members.

When there was silence in the laboratory, a voice suddenly came from outside the door, startling them, and Ge Zi held Mu Mu's hand hard.

"Hi——! Can my friends upstairs hear me? Let's get high! Shake it up! Show me your hands! ”

It was Liu Peijia's gong-like voice.
