"Huh?" Nan Qiyun was a little confused by this strange question he suddenly threw out.

Han Xian rubbed his eyes vigorously, and his eyes were full of disbelief as he looked at Chu Han.

"I mean, do you think Chu Han looks a little strange right now?" He slapped his head again, and his eyes widened.

Nan Qiyun and No. 1 looked in the direction of Chu Han. Chu Han's face showed a puzzled look. Nan Qiyun's brows furrowed, looking at Chu Han's appearance, it really made people feel that something was not quite right, but this indescribable strange feeling was nowhere to be found. Han Xian looked at Chu Han carefully.

Han Xian suddenly pointed at Chu Han's ear. "Here." Han Xian stepped forward, ignoring Chu Han's subconscious obstruction, and tugged at his right ear. Nan Qiyun suddenly realized.

They could actually see the metal wall behind Chu Han through his right ear. Chu Han's right ear was like an image on a projector, constantly flickering and looming, but Han Xian could feel the actual existence of Chu Han's right ear. Originally, this was not an inconspicuous anomaly, but due to the high concentration of the four members of the group for a long time, there was a great sense of visual fatigue, and this anomaly was not visible for a while.

Chu Han looked through the mirror image presented in the anti-pressure window, and he was obviously taken aback by this situation.

"I found out about this situation in Chu Han during the last tracing operation, when I was about to leave that era," Han Xian took out the camera and took a picture of Chu Han's right ear now, "At that time, I thought there was something wrong with my eyes. ”

The photo was quickly washed out. "Look at what is recorded in the photo." As he spoke, he picked up the slightly hot photo.

To his surprise, the images in the photographs were very blurry, and the connection between the people and the surrounding background showed a sense of blur that greatly interfered with the vision. "The camera is broken?" Han Xian pressed the shutter continuously on several other items in the submersible.

Without a clear photo, the blur is so great that it is impossible to tell what the scene is being photographed.

"It may be some kind of influence caused by the retrospectiveness." Chu Han pushed the glasses on the bridge of his nose. "I don't feel much myself."

Nan Qiyun remembered a report he found on Qi Yue's desk in Qi Yue's office before he left, originally he was going to report the situation to Qi Yue, but it happened that Qi Yue was not in the office. When he saw that the title of the report was about the "tracing the stream" operation, he picked it up and flipped through it.

The report describes all the possible effects and consequences of "retrospectiveness" in time. Nan Qiyun noted a phenomenon of so-called "exclusion" that is highlighted in a large number of pages in the report.

The researcher pointed out that since the historical era returned by the "tracer" through the time machine can actually be regarded as the cosmic space of another parallel world, so the "tracer" is actually equivalent to an outsider to this space, then after a certain period of time, due to the protection of the rules of this space by the order of time and space, the phenomenon of "rejection" will occur for the outsider who rashly intrudes into this world that does not belong to this world, which means that there is a corresponding time limit for the tracer to travel in time. As for the consequences of "rejection", the report gives two speculations, one is that the tracer will be forcibly sent back to the era in which he was originally located, and the other is also a more biased speculation in the report, based on the analysis of the previous experiments done by Zhu Yingxin, the reporter believes that if the tracer does not return to the time node of his existence in time after the occurrence of the "rejection" phenomenon, Then it is possible to fall into the turbulence of time and space while being excluded from the world, and eventually be sent to an era, and this random behavior will be irreversible, once falling in, then the streamrunner will become a part of the final era, and will be forever engraved in the past or at some point in the future.

Nan Qiyun looked at the detector on the bridge. The huge image of the ruins is gone, and there is no information about the ruins on the black screen, except for the green dots that represent the small islands of the reef.

The time of contact between prehistoric civilizations and human beings has once again moved forward by more than 1,000 years, which also means that the "black body" may have infiltrated into the human group more than 1,000 years ago, and it is no longer practical to prevent the penetration of the "black body" at this point in time. If there is still the possibility of completing the mission, then the only way to continue to go back to the reign of the first emperor of the Qin Dynasty 1,200 years ago, and to solve the problem of mission execution is how to confirm the time when the "black body" first began to infiltrate the human community. It is possible that all four members of the group will be buried in the wrong decisions they have made. Moreover, it is difficult to guarantee that the source point of the "black body" began to infiltrate was in the era of the Qin Dynasty, and this behavior can almost be regarded as another outright gamble.

But the Qin Dynasty is the earliest time period in which all the information available so far can be extrapolated to the source point. Choose only two, go ahead, or give up.

Nan Qiyun recalled what he looked like when he was a child, the world at that time was so quiet and beautiful, no matter where he was, no matter what he encountered, no matter what he encountered, no matter whether the things he encountered were good or bad, his parents, his two closest relatives, always accompanied him, holding up the strongest umbrella for himself.

In a flash, so much time has passed. The white horse passes through the gap, and the vicissitudes of the sea.

Now, it's your turn to protect the people you're trying to protect.

"We need to continue to push forward to the past point in time." Nan Qiyun proposed the next course of action, since the team could not realistically determine the time period when the source point of the "black body" first infiltrated the human race, then according to the information clues obtained in the process of continuous traceability, layer by layer, then theoretically it could finally return to the original source point.

He did not inform the other three about the speculative hypothesis of the phenomenon of "exclusion". This idea itself is not realistically recognized, and speaking out this speculation at this time will only have a negative impact, and the time and space retrace itself is an extremely risky action, and if the four members of the group are unable to reach a consensus, any disagreement that arises can be fatal, and this is still a hypothesis that is not necessarily correct, and there is no need to pay too much attention to this view.

But Nan Qiyun knew that there would not be much time left for them.

July 15, 2423, Confederate Government, Residence of the President of Shanghai in District 6.

Chen Yuepeng and his staff in the last few months are also anxious, the East China Sea Fleet was destroyed in an instant, which greatly damaged the vitality of the Confederate government's maritime power, and made Chen Yuepeng clearly perceive the strength of prehistoric civilization. During this period of time, the number of infected people has increased wildly without suppression, and in the original 20 districts were almost overcrowded, there was a collective riot of the infected, and the prehistoric civilization actually forcibly transferred all the millions of infected people to the ruins continent, even if not counting some of the infected people who have not been transferred, this huge group alone, in the eyes of the Confederate government, can form a powerful army, if the masters of the prehistoric civilization have this ability. What makes most officials uneasy is that the series of actions of prehistoric civilization and the attack on human power during this period of time are obviously an organized and premeditated action, but for the instigators behind the scenes, the leaders or leading organizations of prehistoric civilizations, the human government has not yet obtained any source of information. The enemies they face are always hiding in the shadows, deliberately hiding their identities, but always dealing a heavy blow to human power in a high-profile manner.

Under Chen Yuepeng's order, the Confederate government spent a huge amount of money to build a tight infrasonic protection network for all regions of the former Eurasian continent, especially the coastal urban areas, using the newly developed large-scale anti-infrasonic devices to prevent the next attack on the ruins continent at no known time.

Chen Yuepeng was holding a map of the distribution of infected people in the F layer in his hand, and now most of the red dots were gathered in the ruins continent above the Mariana Trench, and there were not a few new infected people in the area under the control of the Confederate government, and the situation was becoming more and more serious.

The guard knocked on the door.

"Please come in." Chen Yuepeng put the drawings in his hand on the table.

The guard handed him a stack of papers, then turned to leave. Chen Yuepeng flipped through the documents.

He dialed the communicator on the table. "Execution successful?" There was a hint of anticipation in his tone.

The voice on the other end of the line was slightly muffled. "Hmm."

Chen Yuepeng's brows suddenly relaxed. For him, this was almost the best news in more than a year, and even the successive victories in every battle of the Confederate government against the coalition government did not bring him so much joy.

He quietly set the document on fire, and in the faint light of the fire, the white paper turned to ashes.

The reintroduction of mass use of paper documents is another decision Mr. Chen has made in recent months, even though the initial implementation of the initiative has baffled almost all Confederate government officials.

Regarding the future of mankind, he, like Hua Chengyu, also needs to make a choice at this critical point in time to choose the ultimate future of mankind.
