The more information you read, the greater the doubts you have. The clues inferred from the information are often contradictory, and these contradictions are always traces of human manipulation.

"It takes a substantial piece of evidence." After reading a physicist note in his hand, Xu Changqing closed his eyes slightly and pondered for a moment, and said to himself.

"Boss, I think this file may be useful." At this time, Yakov, who assisted Xu Changqing in sorting the information, suddenly spoke and handed over a file to Xu Changqing.

Yakov was not sure what Xu Changqing wanted to find from these materials, but these days he helped Xu Changqing sort out the information, he had figured out some rules to roughly determine that those materials were valuable to Xu Changqing. The file he held in his hand was accidentally discovered from a bunch of scattered materials classified as other categories. The name on the file reminded him of a rumor he had heard in the Security Committee before, and it was also this rumor that made him feel that this file might be useful to Xu Changqing.

Upon hearing this, Xu Changqing took the file and looked at it.

The first thing that caught my eye was the stamps of more than a dozen confidential departments of the Soviet government on the archives, Stalin's signature and Russian wax seals with sealed meanings. Judging from this scene alone, the importance of this file is enough to show the importance of this file. Afterwards, Xu Changqing stripped the wax seal, opened the archive bag, took out the documents inside, and looked carefully.

The content of this document is not profound. In fact, this is not technical information. It is just a personal file. The archive records the life experience of a Caucasian named Peter Chalkin. Judging from the content of the information, Peter Chalkin is just an ordinary soldier. He has made many military achievements in the Soviet Union's internal and foreign wars and has won several medals of honor. After the end of World War II, he was assigned to the Soviet Atomic Energy Research Base as the head of the guard regiment. Until March 17, 1948, he was suddenly arrested by the Security Committee. The arrest was not recorded, and the subsequent records were cut off. It did not explain the reason for his arrest, nor did it record the ending, which made people feel like he was a slash.

Such a seemingly ordinary life data file is placed in a bunch of scientists' data related to nuclear physics research, which makes people feel extremely strange. There is always an illusion that Selov has collected the wrong data. If this file is placed elsewhere and there are not so many special signatures and seals on it, it will not attract attention at all. But now it is placed in a bunch of nuclear physics-related data, it is obvious that there must be some connection between the two in nuclear physics.

After carefully recalling the information, Xu Changqing found a clue from the date of Peter Chalkin's arrest. The diaries and notes of several nuclear physicists he had seen before mentioned that it was on March 17 that a technical problem that plagued all scientists in the institute for nearly a year and believed that it might take several years to find a solution was solved. The notes did not record the solution and the process of breaking this technical problem. Only in a formal document mentioned that this problem was solved by Igor Vasilyevich Kurchatov, the father of Soviet nuclear physics. Although this was only one of tens of thousands of technical problems, this technical problem was the most critical one. Its breakthrough played a decisive role in the research of Soviet nuclear weapons. A few months later, the Soviet Union's first nuclear reactor was established, and a year later, the Soviet Union's first nuclear bomb detonated.

"Is this Peter Chalkin related to the Soviet Union's nuclear bomb manufactured by the Soviet Union?" Xu Changqing put the archives back in the bag and asked Yakov on the side.

"There was such a rumor back then." Yakov, who had been waiting for Xu Changqing to ask, said what he knew: "The nuclear weapons research base encountered a big problem, and all the planning projects were stuck on this problem. Scientists had no choice, and predicted that this problem would not be solved within a few years. At that time, someone proposed to find a way to steal relevant information from the United States, and the Security Committee also formulated a plan for this, and waited for the above order to issue it. However, the plan was suddenly cancelled later because someone had already solved the problem. The person who solved the problem in the formal document records was Dr. Igor, but in fact, there was a small rumor in the intelligence department of the Security Committee that the problem was solved by an officer of a guard regiment, and this officer was Peter Chalkin."

"This Peter Chalkin is also a nuclear physicist," Xu Changqing asked in a deep voice.

Yakov shook his head and said, "Of course not. He is just an ordinary soldier. His family is a serf. He is illiterate. Even the documents need to be read by others to understand the meaning. Therefore, it was ridiculous for everyone to hear it. However, Peter Chalkin was arrested for political issues and sentenced to life imprisonment. His file was later listed as an Alpha-level confidential file. This file can only be opened by the signatures of several veterans."

Xu Changqing frowned slightly and said, "I spent so much effort to seal this file. Then the content here must be very important, but the content I saw was very plain. Even if these contents were circulated, no one would pay attention to them. It is obviously somewhat contradictory to the strict protection of the file."

Yakov also showed a confused look.

Instead, Vera, who was listening to the conversation between the two, came up and made a guess: "This archive document may not be all, but only part of it."

After hearing Vera's words, Xu Changqing and Yakov couldn't help but look at each other, and then laughed at the same time, making Vera look confused.

"Yes, I'm really a mystery to the authorities. The answer is that simple." Xu Changqing smiled, and then he found Selov's place through his oath karma. When he felt that there was no one else around him, he waved his cane into the air beside him. He saw a space crack that ordinary people could not see with their naked eyes appeared in front of him. Before the crack disappeared, Xu Changqing flew into it and instantly appeared in Selov's office.

In the past few days, Xu Changqing accidentally figured out a method of using an ivory cane to teleport space like in the three realms of Kunlun. Through the isolation and sealing of the cane instantly generated by the cane, he can perform a half-shattering sword force. When he uses this half-shattering sword force through the cane, coupled with the ability of the cane to tear the space, he can open a crack in the two realms and maintain it for about three seconds, which is enough for him to enter the crack.

However, this kind of spatial teleportation completed by using tricks has some defects. Putting aside other small defects, there are two major defects. First, the movement distance cannot be too far, it can only be within the range of the perception of the divine mind, and it must be within the range where the divine mind can mark the teleportation direction of the space. Secondly, it is susceptible to interference from external forces. Once interference occurs, either the crack will disappear in advance or it will move to an unknown place.

In the past two days, Xu Changqing tried to move back and forth in this empty underground factory, proficient in the casting process, and Yakov and others saw it more times, and they were not surprised. Now Xu Changqing moved more than ten times the distance in the past, and his positioning was already reaching the limit that his divine mind could position, so at the moment he entered the space crack, he could not be completely sure whether this casting could be successful.

Fortunately, Xu Changqing was lucky during this period. After coming out from the other side of the space crack, he saw the stunned Selov, and he realized that he had succeeded and pushed the distance of space teleportation to more than ten times.

After being surprised, Selov quickly regained his peace and did not ask any questions about Xu Changqing's teleportation magic. Instead, he stood up like a subordinate and asked Xu Changqing: "Master, do you have any instructions for coming to me in such a hurry?"

"I came to you to ask about other parts of this file." Xu Changqing asked with the file in his hand on Selov's table.

Selov looked down at the unique feature on the file bag, and quickly remembered all the things related to this file, and immediately explained: "This file is the only file, and there is no other part. After Comrade Khrushchev became the first secretary, he began to liquidate the Stalinists in the party and began to destroy some files handled by Comrade Stalin himself. This file is one of the destroyed files. There are three files related to Peter Chalkin. The content of this file is the simplest, just to record the life of Peter Chalkin. Originally, this file should have been destroyed, but due to the negligence of the staff, the file was preserved. At that time, the master told me to collect all the information related to nuclear weapons manufacturing, I thought of this person, so I took the file together."

Xu Changqing asked: "The rumors about Peter Chalkin were true back then."

Selov nodded and responded: "It's true. This incident was a big deal at that time. It was just that I was in Europe, not in China, and it was not handled by the Security Committee. It was the first secretary's office who intervened directly. When I came back, the matter had already calmed down for a year or two, so I was not very clear about the specific content."

Xu Changqing was a little disappointed, thought for a while, and asked again: "Are there any notes or documents left by the parties involved in this matter?"

"No, these documents were destroyed because they were related to Comrade Stalin." Shelov said, pausing again, and said, "Master, you can directly ask the person involved. I remember Peter Chalkin was still alive, but because of the incident that year, he had suffered a lot of torture and was already crazy. He is now detained in a mental hospital in Kazan Prison."

"Are you crazy?" Although Xu Changqing heard from Selov that Peter Chalkin was tortured, he couldn't help but think of the scientists who had lost their souls in the base. After a little thought, he ordered: "Please help me arrange it, I'm going to Kazan Prison." It will be continued.
