It was already completely dark, and it was approaching evening. Sha Ping and House walked out of the lab. They took off their gloves and took the coffee handed by the person next to them, and drank it in large gulps.

"How? Can you roughly determine the cause of death? Paul asked. Paul, Ritter, and Yu Qianhua are still waiting here, and Samantha has already gone back to the dormitory to play games because she is bored.

Sha Ping and House glanced at each other, and House reached out to give way, motioning for Sha Ping to answer the question. Sha Ping handed the empty cup to the guard next to him, motioned for him to pour another glass, and after taking the cup that had been poured again, he took another big sip before he said to Paul, "There is only one corpse in the room, and it is a crooked one." Based on external observation alone, no external injuries were found on the body. The lab was clean, with no traces found except for a few footprints left by the guards who found the body. Inside, we had seen the inside of the laboratory recording the process of the experiment, and it was still that no one else had entered the laboratory in the morning, except for the guards who found the body. The above circumstances basically rule out that Qu Zhiyi and his ilk were killed by people who directly attacked the body with violence. I discussed it with House, and at the moment we both agreed that there were several possibilities for the death of Qu Zhiliu. The first possibility is that he committed suicide. For example, he felt that he had no hope of avenging his younger brother, and he was ashamed of the promise made to them by his parents when they were dying, so he committed suicide by taking poison. The second possibility is that it was an accident. For example, during the experiment, death caused by misingestion of drugs. The third possibility is that he was poisoned in advance and died of poisoning at work. So we recommend performing an autopsy first, and at the same time finding an expert to analyze the drugs in the laboratory to see if some of them are toxic. Then let's look at what kind of situation he belongs to. ”

Paul turned his head to look at Ritter and said, "We don't have a forensic doctor here, and in this situation, we can't just let people from the local area come into the camp for an autopsy. So it is unlikely that an autopsy was performed. Otherwise, Ritter, you can go into the lab and take a look at the reagents in general to see if there is anything abnormal. ”

Ritter nodded, asked the medic next to him for a set of plastic foot covers, a pair of rubber gloves, and walked into the laboratory after being fully dressed. Yu Qianhua looked at Ritter's tall back suspiciously, and asked, "Isn't Mr. Peibo an expert in weapons?" He also understands mutant drugs? In Yu Qianhua's understanding, these are completely two disciplines, one is partial physics and the other is partial chemistry.

Paul explains: "Actually, both of these studies involve knowledge of card slots. From the perspective of the Dark Domain, their principles are the same. To put it bluntly, it's all a question of how to use Reiki. If there is a problem with those reagents, Retter should be able to see some clues. ”

Sha Ping and House were two ordinary people who couldn't bear the cold of the weather, and they waited for a while, and then they were frozen back to keep warm. About an hour later, Ritter walked out of the lab. While taking off his foot covers and gloves, he looked at Paul and Yu Qianhua and said, "Xiaoqu is really nonsense. In the past, he didn't talk about directly using the living extract of the Soul Eater for human experiments, but now he actually took the solid ...... directly" He suddenly stopped when he said this, and turned his head to look at Yu Qianhua.

Yu Qianhua immediately understood what he meant, and hurriedly said: "It's past dinner time, I didn't eat well at noon, I'll go back to eat first." Paul stretched out his hand to stop her and said to Rhett, "Let's cooperate with Mr. Lang and Miss Yu next." And the beginning of friendly cooperation, of course, it is better to release goodwill to each other in advance. If Rhett has something to say, just say it, don't worry about Miss Yu's presence. ”

"That's good!" Ritter smiled at Yu Qianhua and apologized a little for his behavior just now. Then he continued: "I'm inclined to think that Koji died in an accident. From the table where he fell, I found bottles of two medicines. One is a bottle containing a high concentration of Soul Eater Extract, but the inside is empty. The other is the solid, which has half a bottle in it. I guess here's the thing: in order to quickly increase the number of card slots and improve his internal force level, Xiao Qu first took a large dose of high-concentration extract, and at the same time carried out body alienation to forcibly expand the card slots in the dark domain. However, this method did not stabilize the new slots in the Dark Domain, so he forcibly fixed them with a solidifier. In short, he wanted to use this quick method to increase his force value. But this approach is too radical. He didn't consider that the solidifier could not be used directly on the body of a living person, as it would cause unimaginable pain in the Dark Realm. The solidifier itself was not poisonous, so he was not poisoned. He actually ...... It was painful to death. ”

Paul frowned and asked, "He didn't do a good job of researching drugs that inhibit abnormal mutations, why did he ......" Before he finished speaking, he figured out the reason for it, so he turned his head and looked at Yu Qianhua.

"Because he wants to work hard to improve his cultivation before you release me tomorrow, so that he can avenge his brother again!" Yu Qianhua said what was in his heart for Paul. For this reason, he did not hesitate to gamble with his life. As a result, he was so unlucky that he tortured himself to death. After Yu Qianhua finished speaking, she nodded to the two of them, turned around and went back to the dormitory. Paul and Ritter looked at each other and shook their heads almost at the same time.

Sha Ping saw Yu Qianhua coming back from outside from his dormitory window, pushed open the door and walked out and asked, "Is there anything new?" At this time, House and Feng Juan also walked out of their respective dormitories. Feng Juan was also holding a paper bag containing a hamburger in her hand. She stepped forward and handed the bag to Yu Qianhua.

Yu Qianhua thanked her, took the hamburger bag, opened it and ate it in a big gulp, and she roughly explained Ritter's analysis just now while eating. House shook his head, sighed, and went back to his dorm. Feng Juan's face was happy after hearing this. This Qu Zhiliu died by himself, and now the gang leader saves trouble, and there is no need to worry about this person harming her again. She turned around and went back to her dorm, poured a cup of hot tea, and handed it to the helper. Yu Qianhua took it and thanked him again, lowered his head and took a sip. After Sha Ping listened, there was a hint of incomprehension in his eyes.

Early the next morning, Paul arranged for a car to wait in front of the dormitory for the four of them, and sent someone to return the confiscated belongings of the four people. Among them were the tight, tight-controlled airsoft wrapped in isolated metal foil, and the operating ring. Others include items such as Yu Qianhua's earplugs and Feng Juan's helmet.

The guards told them that General Paul had something else to do, so he would not come to see them off in person. So Yu Qianhua, Feng Juan, and Sha Pingren hastily packed up their personal belongings and boarded the departing car. House didn't get in the car, saying he would stay here and keep an eye on Paul to see what he was going to do next.

As the car passed by the playground, the three people in the car looked out of the window. I saw more than 2,000 soldiers standing in a neat square queue on the playground. In the distance, the Star-Spangled Banner of the United States of America was flying, and under the flagpole, Paul, Ritter, and Samantha stood on the flagstand, and Paul was waving his arms and speaking impassionedly to the soldiers. His voice came to Yu Qianhua's ears through the car window. She heard familiar words such as freedom, equality, peace, greatness, unity, and cooperation.

The car whizzed by, leaving Paul's voice far behind. It seems that Paul's important action is about to be officially launched today. Yu Qianhua put her hand on the earbuds next to her ears and considered whether to give Guo Songshan and the others a wake-up call. She thought about it for a long time, and finally didn't enter the game to give a warning. Now she couldn't see the true purpose of the various forces, nor could she see what was better for her, and she knew that Paul must have expected that she might inform the others beforehand, but he didn't seem to care. So, before the situation became clear, she decided that it would be better to wait and see.
