Bai Liu found a cutting knife from the drawer in the dormitory, and held it in his palm to warm it for a moment before he could smoothly pull out the blade. He used the blade to cut through the waterproof cloth, and the things wrapped inside finally appeared.

It is a stack of neatly packaged experimental reports.

These experimental sheets are filled with professional English abbreviations, some measurement data and graphs, and some strange black and white or color-stained slice photos. In short, they are difficult to read and it is unlikely for ordinary people to understand them without the corresponding knowledge.

Bai Liu briefly flipped through it, then looked up at Mu Sicheng and asked, "Where did you find this?"

Mu Sicheng took a deep breath and said, "The basement. When I went out to check the helicopter hangar just now, I found a zippered cellar door hidden under the docking platform. Below is a two-story basement with various experimental equipment and some pickled cabbage and radishes."

"Have you found the experimental record log and related finished papers in this basement?" Bai Liu asked.

The experimental reports of these people's research are so raw that Bai Liu needs at least some basic knowledge to understand what the data in these reports mean.

Mu Sicheng shook his head: "I didn't look carefully, the bag was just on the table, I felt it was very important, so I took it and came up to show it to you."

Bai Liu: "Call Mu Ke over. Follow Liu Jiayi to count the food on the first floor and prepare the portions for us to take out. Mu Ke and I will go down to the basement to take a look."

Mu Sicheng turned around to look for Mu Ke. Bai Liu glanced at Tang Er and handed him the document in his hand: "Can you understand it?"

"I can understand some of it." Tang Erda simply flipped through it and answered quickly, but his eyes stopped on a certain chart. "This chart... This is a chart drawn after using dual-frequency radar echoes to repeatedly detect the thickness of the ice surface. The detection data can be used to see the terrain under the ice surface based on this chart, so that we will not encounter obstacles such as rocks when drilling through the ice layer."

Bai Liu noticed the strange look on Tang Erda's face and asked, "Is there something wrong with this chart?"

Tang Erda hesitated for a moment, then pointed to the caption below the chart: "This chart is a very common ice exploration chart in the polar regions, but the location it explores is Dome A."

"There are only domestic observatories stationed near Dome A, and that area is within the research scope of domestic observatories. Although the atmosphere between observatories in various countries in Antarctica is relatively peaceful, the division of research areas between each other is also relatively clear. Edmund Observatory does not have the ability and qualifications to explore Dome A. In other words, Edmund Observatory cannot have any first-hand experimental data on Dome A."

Tang Erda flipped through a few more pages of experimental report data in confusion: "But they have a lot of ice layer detection and ice core research reports about Dome A. This is not normal."

"One observation station has confidential research data from another observation station." Bai Liu glanced at the data in Tang Er's hand. "Common sense suggests there are only two possibilities."

Tang Erda looked over, and Bai Liu continued to speak slowly: "One possibility is that the domestic observation station, that is, the Taishan Station in the game, took the initiative to share its first-hand experimental data with the Edmund Observation Station."

Tang Er frowned and denied: "This is impossible. This is a serious scientific research data leak."

Bai Liu raised his eyes and smiled: "It seems that Captain Tang and I are both more inclined to the possibility of the worst - Edmund Observatory forcibly obtained the research data of Dome A in some way."

"Or even worse, these guys from the Edmund Observatory directly killed the people from the Taishan Station, and then occupied the Taishan Observatory to conduct scientific research and measurements on Dome A." Liu Jiayi appeared at the door.

She leaned against the door with her arms folded, and looked at Bai Liu with a raised eyebrow: "--I found Edmund's cabin. I feel that this guy is not a cold-hearted scientist. Judging from the remains in the cabin, he is quite aggressive."

"Take us upstairs and take a look." Bai Liu stepped forward and took Liu Jiayi's hand. He naturally exchanged his warm gloves with Liu Jiayi's empty gloves and put them on her.

The scientific researchers at Edmund Station are all tall and strong, without a single child, so the matching clothing is also wide. Even Bai Liu's top has to go above her knees and ankles, not to mention Liu Jiayi.

Although Liu Jiayi had the foresight to wrap herself up with several pieces of clothing, which looked neat, the gaps in the clothes inevitably let in air, such as through her gloves.

But Liu Jiayi was very strong-willed and didn't like being taken care of. Now her hands were so cold that they were almost frozen, but she didn't say a word and didn't show it on her face. She looked much more serious than Mu Sicheng, a grown man in his twenties.

Bai Liu changed his gloves so naturally, as if he was born to change the gloves for Liu Jiayi. Others didn't even react to what he did.

Liu Jiayi paused and held Bai Liu's hand: "Edmund's cabin is on the 4th floor."

She didn't like this kind of aggressive man, who always reminded her of bad things, and made her subconsciously repulsive and anxious. But Bai Liu was also an absurdly aggressive man, but she couldn't see it at all...

Liu Jiayi squeezed the warm and wide gloves that Bai Liu had just taken off, covered her face with her hands, exhaled a breath of water vapor, pursed her lips, and her expression became much calmer.

Although Bai Liu was also quite annoyed, she didn't know why, but she just accepted this person well.

Liu Jiayi led Bai Liu all the way to the corner, where there was a room that was about one square meter wider than the other cabins. When Bai Liu walked in, he looked up and saw the wind constantly drilling in through the cracks in the seals on the window, whizzing past and taking away all the warmth.

Around the seal, there were icicles as thick as a ballpoint pen, dripping and condensing, which glowed in the dim light.

Liu Jiayi stuffed the gloves into her pocket and said, "At first I didn't realize this cabin was where the boss, Edmund, lived. This cabin is located in a windy place and will be the first to be blown away in any blizzard. It's too dangerous for a base manager to live here. He might freeze to death in his sleep."

"But I found this behind the door." Liu Jiayi kicked the frozen door.

The icy door snapped and then slammed shut with a bang as the wind blew. On the door hung an iron hook, on which hung neatly a row of 70cm long modified rifles, the muzzles of which were also covered with icicles.

"I didn't find any traces of gunfire in other rooms. They were mostly filled with books, computers, medicines, etc. Only this room had a gun and a lot of reserve bullets."

Liu Jiayi hooked her toes on a box under the bed and pulled it out with all her strength. She let out a long breath and stepped on the neatly arranged 7.62mm bullets in the box with her toes, saying sarcastically:

"At first I thought it was to observe some military personnel in the station, but I found a purchase invoice for reimbursement under this box of bullets. The guns and bullets were all purchased in Edmund's name. This should be his living quarters."

Tang Er frowned and said, "The Antarctic Convention prohibits the use of firearms and other military weapons by people at the observation post. It is also strictly forbidden to store similar items here."

Liu Jiayi shrugged, "But he did use it. I looked at the purchase date and notes on the invoice. He had already arrived in Antarctica and asked the Antarctic helicopter transport team to buy and ship it to him for the sake of self-protection."

"And he should have lived here alone. I didn't find any signs of a second person living here. I guess no one else knew that he had a gun."

Bai Liu glanced at the pile of rifles, then stood at the door, simulating a virtual gun-raising posture, and peered at the front of the building through the non-existent sniper hole with half-squinted eyes:

"So this Edmund bought a bullet rifle in the name of self-defense and hid it in the room. He would rather live alone in the extreme cold draft cabin and risk being frozen to death. He held the gun in the cold every day, and the only people he could aim at were the people in the other cabins on this corridor-"

Bai Liu put down the "gun" in his hand and said with some interest: "It seems that this Dr. Edmund is afraid that other people in the observation station will attack him, and he is so scared that he wants to buy a gun to protect himself."

Mu Ke walked up from the third floor to the corner of the fourth floor, followed by Mu Sicheng.

They saw Bai Liu at the end of the corridor. Mu Ke walked over with a slightly serious look on his face, took out a large stack of lists and handed them over, explaining, "When Mu Sicheng and I were preparing food for your trip, we saw that a lot of fresh food in the warehouse had rotted, and a lot of canned food was left untouched in the warehouse, with the outer seals not even opened."

"Mu Sicheng and I both felt something was wrong, so we checked the receipts that record the consumption of food and medicine. I took a quick look at it and didn't find anything wrong at first, but then I discovered that the amount of food consumed under the "Required Intake Consumption" item on the receipt didn't match the amount of food left."

"But later I carefully checked the consumption of food and medicine, and found that although the [necessary intake consumption] records the names of food, the food items above do not represent real food. These foods actually refer to various medicines, such as bread referring to [lithium carbonate]."

Mu Ke looked at Bai Liu intently: "The people in this observation room take drugs as food, they are supplied with drugs three times a day, and someone is forcing them to take these drugs."

Bai Liu asked, "Do you know what kind of medicine it is?"

"Lorazepam, dioxetine, chlorpromazine, olanzapine..." Mu Ke listed a long list of drug names without pausing, and then concluded, "Most of them are psychological treatment drugs for severe depression, severe anxiety, and mania."

"The people at Edmund Observatory take a lot of these drugs every day, and they don't even eat much." Mu Ke took a deep breath. "If this is really the case, then this place is equivalent to a mental hospital in the polar regions. These people are all in very good physical condition, and they are seriously ill patients who are very aggressive when they get sick."

Bai Liu moved his gaze to the floor of Edmund's room, where there was a whole box of cold bullets.

"I think I understand why Dr. Edmund bought guns and bullets." Bai Liu said softly, "He is trying to detain and control these dangerous patients."
