Time passed day by day, and the zero-dimensional robot that reconnoitered the dimensional passage still did not reach the end of the passage.

Looking at the range of the zero-dimensional robot, it has exceeded 130,000 megagrids, such a long distance is a bit beyond Lao Qin's expectations.

A ghost agent suddenly detected an anomalous dimensional fluctuation and immediately manipulated the zero-dimensional robot to infiltrate it.

Soon, a dimensional crack appeared not far away, and the zero-dimensional robot cautiously approached and smoothly entered the gap.

It's just that the ghost agent, the moment the zero-dimensional robot enters the dimensional crack, the whole person is stunned.

"How is that possible?"

Lao Qin on the side hurriedly asked, "What did you find?"

The ghost agent hurriedly told Lao Qin the situation: "The zero-dimensional robot I controlled has returned to the entrance. ”

“?” Confused, Lao Qin flipped through the navigation logs of the zero-dimensional robots, and sure enough, some of the zero-dimensional robots returned to the vicinity of the previous entrance.

I double-checked it twice and it was still the same result.

Then there were other ghost agents' zero-dimensional robots, one after another, coming out of the entrance.

"Could it be that the entrance and exit of this dimensional passage are connected?" Lao Qin touched his big bald head, a little puzzled by this.

He made the zero-dimensional robots that were still in the dimensional passage stop in place, especially those that were in the dimensional passage and not far from the exit, constantly probing the surroundings.

On the other side, he re-dispatched a batch of zero-dimensional robots to enter the dimensional passage from the entrance.

The zero-dimensional robot that enters the dimensional channel from the entrance, but does not encounter the zero-dimensional robot on the inside of the exit.

Obviously, this dimensional passage is a passage that is connected from end to end, but the entrance can only enter, not exit; And the exit can only go out, not enter.

I tried back and forth a dozen times, and it was still this result.

Lao Qin's heart became even more puzzled: "If the dimensional channel is a one-way ring channel, where does the primordial beam of the distress signal come from?"

Obviously, this problem contradicts the one-way ring channel.

Lao Qin once again organized ghost agents to conduct a comprehensive exploration of the entire dimensional passage, hoping to find any clues, especially the source of the distress signal, which is the main point of the investigation.

The results of the carpet search really made the ghost agent find something.

In the depths of the dimensional channel, countless zero-dimensional robots float in the vacuum, and this section of the dimensional channel has an obvious dividing line.

There are dense distress signals on one side and sparse distress signals on the other, and this dividing line may be an important clue to decipher the channel.

After careful detection and analysis, some patterns of the channel were discovered.

In the passage on the entrance side, the distress signal is obviously much sparse; On the exit side, distress signals are noticeably denser.

This dimensional channel seems to have the characteristics of circulation, which can discharge the things inside the dimensional channel along the dimensional channel.

Near the demarcation line, there was apparently a source of distress signals, but no matter how much the ghost agents searched, they just couldn't find the alleged source.

Those primordial beams carrying distress signals seem to appear in the dimensional channel out of thin air, and then diverge to both sides of the channel, but the presence of channel circulation makes the distress signal density on both sides different.

The investigation work was still clueless, and Lao Qin and the others could only continue to circle in the dimensional passage.

43 years have passed unconsciously.

During this period, the ghost agents led by Lao Qin were still at a loss in the investigation of the dimensional channel.

However, in another matter, the progress has gained something, and that is the analysis of distress signals, accumulating decades of data, so that the ghost agents have a full understanding of these distress signals.

These distress signals do not come from the same civilization, but from 12 civilizations, all of which are at the level of the Great God Civilization.

Judging from the analysis of some distress signals, these civilizations seem to have been lost in this dimensional passage and have no way to leave.

Lao Qin and the others were also skeptical of these analysis results, because the ghost agents had investigated the dimensional passages for decades, and still did not find these trapped civilizations.

The ghost agent tried all means, but the dimensional passage was still empty, only the distress signal that appeared out of thin air.

As staunch materialists, the new human beings obviously do not believe in the theory of gods and ghosts, and that matter cannot appear or disappear out of thin air, and there must be some kind of rule mechanism in this.

After some careful consideration, Lao Qin came to Fang Changkong's office.

"Commander Fang, I want to personally lead the team and enter the dimensional passage to investigate."

Fang Changkong was a little hesitant about Lao Qin's request, this was not the first time Lao Qin had applied to enter the dimensional channel, because of the possible risks, he had to consider it carefully.

"Old Qin, this dimensional passage is too weird, I think it's ......"

Facing Fang Changkong's bitter heart, Lao Qin shook his head firmly: "If you don't enter the tiger's den, you can get the tiger." Please ask Commander Fang for permission to act. ”

Looking at Lao Qin, who was unswerving, Fang Changkong finally agreed to Lao Qin's plan.

Soon, Lao Qin took 10 ghost agents and drove a dimensional spaceship into the dimensional passage, and the interior of the dimensional passage was still the same and strange.

And Lao Qin, who personally led the team, felt a kind of snooping, but on various detectors, everything was normal.

Just as the ship arrived near the demarcation line for the distress signal.

Abnormal protrusions.

Before the ship knew it, it had entered a strange dimensional passage.

By the time Lao Qin and the others reacted, the spacecraft had no way to leave, they and the fleet lost quantum communication, and when they tried to return the same way, they encountered an unfamiliar spaceship.

The other party's scientific and technological level was average, and it was quickly taken down by Lao Qin and the others, and after obtaining relevant information from the spaceship, they knew that they had entered the endless corridor of the 12 civilizations.

The civilization of this spaceship, an expedition ship that strayed into the Endless Corridor a long time ago, has been trapped here for more than 1.7 billion blue star years.

Lao Qin discussed with the three technical ghost agents, knowing that it was impossible for them to escape from here for the time being, so they could only modify a special communicator to transmit the information here.

And the flotilla side.

As soon as Fang Changkong received the news that the exploration spacecraft was missing, he was in a hurry, and he fell into a dilemma for a while.

Just when he didn't know what to do, a signal from Lao Qin and the others came from the dimensional channel.

After learning that Lao Qin and the others were temporarily safe, he breathed a sigh of relief, but what happened next gave the head of the house a headache.

Lao Qin and the others were trapped in the endless corridor, but the fleet had no way to rescue them, so they could only stare at them outside.

Judging from the descriptions of Lao Qin and others, once the intelligent creatures enter the dimensional channel, a certain mechanism of the dimensional channel will be activated, pulling the intelligent creatures into the endless corridor.

According to the information obtained from the captured spaceship, there has been no case of intelligent beings who have entered the Endless Corridor successfully escaping.

In the endless corridor, in addition to the 12 great god civilizations that emitted distress signals, there are actually 4 intelligent creatures of the great god civilization, who can't stand the endless loneliness and choose to cut themselves off.
