Mu Mu's body was a little chilly, and there was silence all around, only the sound of his heavy breathing and staggered footsteps, and the floor on the second floor was full of ice ballast, which clicked when he stepped on it.

Cassini Station is a rectangular building with a hall in the middle of the second floor and doors on both sides that lead to the living area on one side and the office area on the other.

Mu Mu stood in front of the door, it was a white door, there was a small round window on the door, but the window glass was blurred, Mu Mu pulled it away slightly, a little difficult, the airtight door was very heavy, the hinges of this kind of door were not allowed to open and close at will in design, plus the friction between the door edge and the frozen floor increased, she opened the door, and the time that had been silent behind the door for twenty years was stirred, and Tie Futu stepped in with a headlamp.

Mu Mu walked down the hallway, and there were rooms on either side.

She raised her hand to wipe the stain from the door, trying to make out the words on the nameplate.

Infirmary.

"Dai Yue, have you found anything?"

"Everything works." Headset answers.

Mu Mu unscrewed the door to the infirmary, a little apprehensive, she couldn't tell what she would encounter on the second floor.

She's just betting.

She wanted to validate a thought in her heart.

The infirmary was pitch black, the second floor was completely cut off, I don't know where there was a problem with the wiring, and there was no way to repair it, the pillar of light from the Tiefutu headlamp fell on a black figure, and Mu Mu almost screamed.

In the infirmary sat a man with his back to the door, his body covered with a black veil, motionless.

Mu Mu slowly stretched out his hand and pulled the cloth off suddenly, only to find that it was an armchair, a chair used in the infirmary for physical examination.

"Mumu, did you find anything?" Ge Zi asked, "I'm so bored down there, I want to go up and have a look." ”

"It's dark up there." Mu Mu said, "Do you want to come up too?" ”

"But it's as dark down there." Ge Zi flattened his mouth and sighed, "It's not just dark, it's still very windy." ”

Mu Mu rummaged through the infirmary and pulled out a round helmet from the box, which she had also found in the P3 lab below.

A portable, precision, high-energy scanner that is also a gamma knife.

"Xiaozi, Brother Shi, have they come back?" Mu Mu asked.

"Hmm...... Let me see......" Ge Zi said, "No, I didn't see the lights at all." ”

The worry in Mu Mu's heart was a little heavier.

She fiddled with the helmet in her hand and looked at it carefully, this thing was a common tool in Cassini Station, and it was also the murder weapon that Mu Mu speculated killed Hu Donghai twenty years ago.

It can use high-energy electromagnetic waves to precisely scan biological tissues to create fine structures, and it can also break through safety limits and destroy the human brain with ultra-strong gamma rays.

Mu Mu slowly narrowed his eyes.

It's a biological or medical tool.

Not a mineral research tool.

In the Mineralogy Research Laboratory, there are super-powerful SEMs and higher-energy pulsed lasers, with a power of more than 4,000 Three Gorges hydropower stations.

But why did they bring this thing into the P3 lab twenty years ago? Mu Mu silently thought, what was this helmet used for research at that time?

She may be close to the truth.

"Xiao Zi, I found a gamma knife in the infirmary."

"Gamma knife?" Ge Zi didn't remember what it was for a while.

"It's that helmet, we found one in the lab, remember?"

Ge Zi was stunned for a moment, and then remembered, "Oh, oh, oh, I remembered!" Didn't you say that Director Hu Donghai was killed by it? But we can't find the murderer, is there anything wrong with this thing? ”

"I'm wondering...... Mu Mu left the infirmary and continued to explore, "why did they bring a bioscanner into the lab?" ”

"Maybe it's to study that black ball?" Ge Zi said.

"Maybe there's something else besides the black ball." Mu Mu pushed open another door, this is the archive room.

There are rows of tall filing cabinets in the archives, and the solid hard disks in the cabinets are stacked on top of each other like books, and from today's eyes, solid hard disks are undoubtedly quite backward ways to preserve information, but twenty years ago they were still a reliable medium for data preservation, and the archives are one of the most important areas of Cassini Station, where all the backup data in Cassini Station is kept, and the date is affixed to the spine of the hard disk case.

Mu Mu patrolled from cabinet to cabinet with her headlamp on, like a library night watchman, alone in the dead of night in the closed stacks, the lights flickering in the gap between the glass and the cabinets, and she carefully identified the dates on the boxes.

“2098……”

“2099……”

"2100...... October, November, December ......"

The year is clear.

Mu Mu walked all the way back and went straight to the area he was looking for.

Year 2101.

Mu Mu was stunned.

This column is empty, and there is no archival record for the year 2101.

Is it because of the urgency of the situation that they didn't have time to file it?

"I'm in the archives." Mu Mu leaned against the cabinet and exhaled.

"Did you find any important clues?" Ge Zi asked.

"Nope." Mu Mu was quite disappointed, "There was nothing left in 2101. ”

Mu Mu had wanted to come here for a long time, and she saw that there was an archive room on the second floor on the interior layout of Cassini Station, and she thought that there might be more detailed and complete information in the archive room.

Sadly, her expectations were disappointed.

"Is it because they had an accident before they could sort out the files?" "In such a turbulent and urgent environment, I'm afraid no one can organize the records in a slow and orderly manner. ”

"I was negligent." Mu Mu rubbed his helmet, "Brother Shi, are they back?" ”

"Nope." Ge Zi and Zhuo Zhi spoke in unison.

Mu Mu glanced at the time, it was nine twenty.

Forty minutes remaining.

In addition to the archive room, Mu Mu was not very interested in the other rooms in the office area, and then there were two warehouses, the doors were still locked tightly, Mu Mu couldn't unscrew it when he twisted it hard, and finally imitated the anti-terrorism special police and broke into the door with a loud shout.

There were some unused tools in the warehouse, Mu Mu squatted down and fiddled with them one by one, and asked Ge Zi:

"Xiao Zi, there is a super-intelligent quantum computer-controlled laser ranging nano-level vise here, do you need it?"

"And the F566 portable variable cycle large bypass ratio turbofan tandem scramjet hair dryer, do you need it?"

"There is also a miniature liquid oxygen methane four-combustion chamber high-pressure refueling rocket-powered recyclable ***, what do you think of this?"

"and the inland Taipan snake purified toxin mixed botulinum toxin automatic trapping sticky mouse plate...... Strange, what is the purpose of sticking the mouse board here? ”

Mu Mu shook his head.

She got up and was about to speak, when she suddenly realized that Dai Yue hadn't made a sound for more than ten minutes.
