As early as when Becca came forward and ended the war between the Yamora and the humans and the Akula, Chu Tianjiang thought that he should go to the star system of the Ponzhi family to learn about the intelligent civilizations created by the members of the Ponji family, that is, the opponents that the human race might encounter in the next war.

It's just that Chu Tianjiang has never had time to do this.

Of course, before mastering the secret of the space debris of the four-dimensional universe, even if Chu Tianjiang had similar thoughts, he would not be able to go to the star system of the side branch family.

Although in theory, the creator can use the space bridge to travel to any location in the three-dimensional universe, in reality, the use of space bridge is greatly limited. This is the situation where the creator must know where the road is going, that is, the exit of the space bridge. If you accidentally open the exit of the space bridge inside the black hole, even the creator will not be able to escape.

For a creator like Ali, all she knows is the situation within the family.

In other words, the vast majority of the creation of the Dao is only the distribution of the star systems within the family, and the general state of each star system.

Strictly speaking, even Becca didn't know much about the situation of the side branch family.

The reason is that before the end of dimensionality reduction, each family determined the specific position of the star system created by each creator in the three-dimensional cosmic space according to the actual situation. Because this matter must be done by the patriarch, the patriarch is the creator of the most descending dimension in the family. The problem is that the patriarchs of all families are the last to descend, so they may not know the distribution of the galaxies of other families in the Dao.

After coming to the three-dimensional space, the situation became even more complicated.

The point is that in the three-dimensional universe, time is unidirectional, and speed is limited. If two families are separated by a distance, say hundreds of millions of light-years, then it will be hundreds of millions of years before you can see the light from the stars of the other families. What's more, even if you do, it was hundreds of millions of years ago, and all galaxies are in motion, and some galaxies have very short natural lifespans. In other words, even if you do, those galaxies are somewhere else, and they may have collapsed into black holes. What's more, after the outbreak of the intelligent civilization war, many star systems have disappeared, and the environment of the entire three-dimensional universe has changed.

In the Beka family's war of intelligent civilizations, tens of millions of star systems were completely destroyed, and some of them collapsed into black holes. For the two side branches of the other cantilevered families of the Milky Way, it would take at least millions, if not tens of millions, of years to see these changes, and it would be known that many of the star systems of the Bekaa family no longer exist. Similarly, the creators of the Becca family also need to wait millions or even tens of millions of years to discover the changes in the side branch family, and the Zhilu Dao side branch family has also broken out in the intelligent civilization war, and many star systems have been destroyed, and some of them have collapsed into black holes after the destruction.

In fact, this is the main reason why Becca came forward to end the war of intelligent civilizations.

That is, the war of intelligent civilizations also broke out in the two side branch families, and the scope was very wide, and many star systems were destroyed by intelligent civilizations or creators in the war. Because Becca saw what happened millions of years, or even tens of millions of years ago, and the Becca family's wisdom civilization war lasted only tens of millions of years, there is reason to believe that the wisdom civilization war of the side branch family broke out almost at the same time. If the situation is similar, then the war of wisdom civilization of the side branch family is probably over.

Obviously, after the end of the war of wisdom civilizations within the family, the next step is external expansion.

The War of Intelligent Civilizations has changed the face of the entire galaxy, which has also raised the problem that the scope of use of space bridges is severely limited.

In fact, even if the exit of the space bridge is not opened in a black hole, there is a great risk.

That is, if the exit of the space bridge is not inside the star system, but outside the star system, and it is far enough away from the nearest star system, it will be difficult for even the creator to figure out the exact location of the space-time trajectory created by the space bridge after the space-time trajectory is gone. In this way, even if the space bridge is opened again, you will not be able to return to your own star system, but may be lost in the three-dimensional space.

Relatively speaking, the three-dimensional universe is very empty.

In the entire three-dimensional space, the space occupied by star systems is only equivalent to one trillionth, and the rest is the vast space between star systems and star systems. There is nothing in these spaces, and even the energy is scattered, and it is impossible to provide a suitable living environment for the creator. If the creator does not grasp the source of the star core and gets lost in these spaces, he will still be finished after running out of energy.

It is precisely because of these restrictions that a creator like Ali, even Becca, would not venture to the star system of the side branch.

It wasn't until Luo Jinyong discovered the secrets in the four-dimensional space debris, discovered that he could travel through the four-dimensional space debris to go to any location, and was able to enter the black hole through the four-dimensional space debris and rescue the intelligent life trapped in the black hole, all this changed. The point is, space travel through four-dimensional space debris is much less risky than using space bridges.

First of all, don't worry about falling into a black hole.

Of course, it is still possible to fall into a black hole using four-dimensional space debris for space travel, but in the case of someone traveling with you, falling into a black hole will not have serious consequences, that is, the intelligent life left in the four-dimensional space debris can rescue the companion who fell into the black hole.

Most importantly, the principle of using space debris in the 4D universe for space travel is very different from using space bridges.

That is, it is only necessary to know the destination of the Lung Road, and it is not necessary to know the exact situation of the departure place of the Lung Road. To put it more directly, the use of four-dimensional space debris for space travel must first enter the four-dimensional space debris, and after entering the four-dimensional space debris, the relationship with the three-dimensional space has been severed, and the user only needs to know the way to the place to go, and open the level of the four-dimensional space debris near the destination, and then exit from the four-dimensional space debris, which is not directly related to the starting point. In this way, even if the user does not know the exact location of the starting point of the tunnel, there will be no impact on space travel.

Obviously, this is a key attribute that space bridges do not have.

If you use a space bridge, you must know the exact location of the starting point and the destination of the road in order to find the corresponding parallel space. If you don't know the exact location of the starting point of the road, you won't be able to find the corresponding parallel space, so you won't be able to reach your destination.

Obviously, this is a more desirable means of space travel, and it can only be used by intelligent life.

It is simply impossible for creators to travel in space using space debris in the fourth dimension, unless they are willing to give up their identity as creators.

"No matter what, the three of you have to act together, especially when you come out of the debris of the four-dimensional universe, you can only let one person out of the sky first, and then let the other two people out of the sky after figuring out the situation outside." Luo Jinyong focused on admonishing Chu Tianjiang. "If you're in trouble, you have to get back as soon as possible. Again, what I said at the beginning, in any case, the three of you have to act together. ”

Chu Tianjiang nodded and agreed, Luo Jinyong had already said this precaution several times.

"Actually, you shouldn't take that risk." Luo Jinyong said it several times, in fact, he wanted Chu Tianjiang to know that it was very risky to go to the star system of the side branch family. The gains corresponding to the huge risks may not be as good as Chu Tianjiang and Zhang Xiaogang imagined.

"Professor." Zhang Xiaogang sighed and said, "Lao Chu is a very measured person, don't worry about him." ”

Luo Jinyong closed his mouth, he knew that no matter how much he said, it was useless.

"I won't say more about what the professor said." Zhang Xiaogang turned his head and said to Chu Tianjiang, "Your task is only to find out the situation of the enemy, especially the wisdom and civilization of the side branch family. You have a sense of measure, know what to do, and don't take unnecessary risks. All in all, war is about to break out, and there is no need for you to take any chances. Once you have figured out the situation, you have to rush back as soon as possible and participate in the combat operation. ”

Chu Tianjiang nodded and said, "I know what to do, and is there anything else I need to pay attention to?" ”

Zhang Xiaogang sighed and said, "If you don't come back in time, or if Beka starts a war before you come back, we will have no choice. When the time comes, I will send someone to find you. If you can't go back if you're in trouble, you'll have to find a place to hide. ”

Chu Tianjiang smiled reluctantly and didn't say anything.

"If we win, the men I sent will surely find you." Zhang Xiaogang paused slightly, "If we lose, you have to remember, don't try to change the outcome of this war, you have a more important mission, and only you can complete it." ”

Chu Tianjiang nodded, indicating that he understood what Zhang Xiaogang meant.

In fact, this is the fundamental purpose of Zhang Xiaogang asking Chu Tianjiang to take Ali and Beya to the Panzhi family to investigate the news, that is, to let Chu Tianjiang avoid the limelight. According to Zhang Xiaogang's arrangement, if human civilization loses this war, Chu Tianjiang will have to try to rebuild human civilization.

Of course, there is a problem that Zhang Xiaogang did not say clearly, but Chu Tianjiang can completely think of it.

That is, human civilization has to deal with not only the intelligent civilization of the side branch family, but also the threat from Beka. Chu Tianjiang left with Ali and Beya, just to let Becca throw a mouse.
