The experience of shuttling through the portal is certainly far from the first time for Chu Nan.

However, this portal shuttle, which is obviously not stable and fully formed, is the real first time. Just after entering the extremely dark starry sky, he immediately sensed the disharmony and irregular fluctuation of energy fluctuations transmitted from the surrounding space.

Moreover, he can clearly feel that the ability fluctuation in this special space is weakening in a small range, which proves that although the portal has maintained itself for a long time, it is still irreversibly assimilated by the positive space universe and will disappear completely sooner or later.

Due to the lack of observation time, Chu Nan cannot determine whether the assimilation comes from the assimilation of the portal itself or the assimilation of special space caused by the power of domain space. However, it is certain that the speed of assimilation is not fast, but it cannot be completely ignored. The time left for him to enter the portal for exploration is not unlimited, so he has to hurry up.

Perhaps it is the conclusion obtained from the analysis of a large amount of data in the strong brain, or pure intuition. Chu Nan feels that it is impossible for the enemies who set up ambush attacks or the three enterprise warships to disappear completely.

Even if it is true, as Alcatel said, behind this incident is the secret cooperation of the erewarner military treaty alliance and the Declan Empire to block the information to this extent, and even the whole battlefield leaves no trace, it is not so easy.

Their disappearance is likely to have a lot to do with this portal.

So Chunan did not hesitate to chase into the portal. After all, he was sure that there would never be a second person in the whole galaxy who knew the mechanism of the portal better than him, because no one would have a brain as strong as a light brain and the research theory of the portal by both the diklan Empire and the noahtham chamber of Commerce in recent years.

Although the situation in the portal is worse than that of the normal portal in the endless abyss, it is not to the extent that it is completely impassable. After calculation, Chu Nan easily found a complete track from the special energy fluctuation flowing in it, and then felt it along this track.

The space in the portal is different from the ordinary different space. Compared with the passage in different space, the passage time in the positive space universe is greatly compressed. The space in the portal is equivalent to the high-strength compression of the passage in different space again, but maintains another completely different stable energy structure. On the contrary, it is not as powerful as the violent space energy in different space, Therefore, in general, the shuttle in the portal is very safe, and it can travel through space faster.

But this will also bring a problem. Chu Nan can't perceive the outer positive space universe in the portal at all, so he can't determine his coordinate orientation at all. He can only touch it little by little along the energy trajectory.

After about half an hour of walking, according to the research results obtained in the endless abyss, the walking distance has been equivalent to a long distance of more than 400 light-years. The thick and rich space in the portal in front of Chu Nan's eyes, which makes people unable to distinguish the direction, suddenly stabilized, and a few stars jumped out of his vision. Finally, he successfully passed the entire portal.

After scanning the line of sight, you will find that in addition to a few stars shining in the dark starry sky around, there is also a much larger fireball burning out of thin air in the starry sky far ahead on the right.

Obviously, it should be the nearest star.

Of course, the so-called "distance is very close"... Even if there is no accurate scale calculation, it should be at least more than a few light-years away.

Chu Nan took a look at the portal that escaped from behind and felt the release. Sure enough, he still felt the energy fluctuations in those fields left around the portal. However, compared with the portal, the portal fluctuation on this side is much weaker, and the portal stability on this side is far less than that on the other side.

He was absorbed in the vicinity for a while. Through the weakening trend of energy fluctuation, he roughly judged that the portal here could still maintain stability. The transmission time should be between 37 minutes an hour and 43 minutes an hour.

After thinking about it, Chu Nan turned around and drilled back into the portal.

With the previous shuttle experience, Chu Nan took a lot less time to go back this time. He jumped out of the portal at the other end in only five minutes.

As soon as he appeared, Alcatel immediately found him.

"Hoo -" Alcatel was obviously relieved. "You just jumped in. Don't you think about what to do in case of any danger?"

"Have you forgotten my ability?" Chu Nan pointed to his head. "If I detect something wrong, I will definitely return it as soon as possible."

Alcatel shrugged helplessly.

He spent more than a year with Chu Nan in the endless abyss. Because of the study of the portal, Chu Nan's ability has been fully demonstrated, and he knows better than others.

"Did you find anything?"

"Not yet, but I'm basically sure that the other party should have jumped away with the whole fleet through the portal." Chu Nan pointed to the starry sky covered by the huge portal behind him. "The portal still has traces of their residual energy fluctuations, but we can't see where they're going for the time being."

"Well... Do you know what star field corresponds to the portal?" Asked Alcatel again.

"It's about four hundred years away from the Milky way. It shouldn't be in the dark. It's just one year away from the Milky way."

The so-called dark star region refers to the "three noes" star region that has not been fully explored, or has been explored but ignored because it has no value. It is only slightly marked on the star map, but there is no human civilization stationed, no star gate connection, and no Pan Galactic network coverage.

The star field that Chu Nan just jumped through the portal completely conforms to this feature.

This kind of star domain is more or less said in the whole galaxy. After all, the galaxy is so vast that it is basically impossible to explore it completely.

However, this cosmic region is very close to the United States of America. There are not many similar dark star regions, which are naturally easy to distinguish.

Chu Nan answered as he opened his personal terminal, connected to the pan Galaxy network and began to search the nearby star map.

On the other side, Alcatel did the same.

Both of them have much more powerful brains than ordinary people. They soon confirmed a piece of conditions from the star map, which just meets the star domain mentioned by Chu Nan.

Alcatel frowned, but Chu Nan smiled.

"Hey, what a coincidence."
