Although he remembered leaving the world in his past life, that was his first time leaving after reincarnation, so he couldn't avoid remembering everything while observing the world from outside.
From the time when he was just a bookworm in the Roanmad Clan to the moment he left, a lot of things happened to him.
Yale strived to turn strong despite having lost his memories and made a lot of friends on his journey, but at the end, he was forced to bid farewell to them to continue his path.
Although he didn't want that outcome, his future progress would be hindered if he remained in that world, and his friends were too weak to follow him.
"Train hard, and maybe one day we will be able to travel together once more."
Yale only thought those words, but he really hoped that one day they could travel together again.
However, their paths needed to separate for the moment as finding the Battle God to rescue Yale's father was an important mission that they couldn't delay until the other turned strong enough.
After all, although there were counted exceptions like Shiba, without having a past life or Condensed Essences, becoming an Essence God in less than a hundred thousand years was almost impossible. In fact, advancing in less than a million years after having been born was enough to be considered talented.
Of course, there were methods to hasten the speed, but those could at most be used by an Essence God towards someone who was a Law God and had a powerful soul. Otherwise, it would be more harmful than beneficial.
Eini was a Law God with quite a powerful soul, so Shiba had been helping her, but since she had lived only a bit more than thirty thousand years, it was still difficult for her.
After all, although Eini soul was quite powerful, it wasn't as powerful as the souls of Yale, Lina, and Shiba when they advanced to Essence Gods, so she was still a bit lacking.
Lar was the only one among Yale's friends with the potential to become a Law God in a short time because of her past life, but her soul was weaker than Eini's, and the time she would need to advance to an Essence God even with help would be enormous.
The rest would probably need a lot of time even to become Law Gods. After all, they didn't have any cheat like a Condensed Essence that could help them to train faster.
Wyba and Aiwai would have an easier time because they were tied to Yale's soul and that made their path a bit easier than the others. At least, with enough effort, it was difficult that any of Yale's friends became Law God before them. However, Aiwai and Wyba didn't put all her effort into training, so it was difficult to guess how much time they would need.
Although becoming a Law God wasn't as hard as becoming an Essence God, without previous lives or special means, it was almost impossible becoming one without having lived at least a thousand years.
In the same way, those who became Law God while being less than ten thousand years old were considered talents, and Yale's previous life and Lina were among the quickest to reach that level in their generation.
It wasn't without reason that they were considered part of the group of the five most talented Law Gods.
Stopping to think about the chances of his friends to reach a level safe enough to travel again with him, Yale turned his back to the world and moved towards where the other three were waiting for him.
All of them understood that it was normal for Yale being a bit emotional, so they had let him time to set his mind before continuing their journey.
Without saying anything, the four of them started to fly quickly leaving the world behind them. After a short time, they were unable to see the world, but they didn't turn their head to look back.
Although they didn't know about where the Battle God was, they knew that he wasn't near the world where they were before.
The world that Yale's father gifted to Yale was quite isolated and the surrounding planets were all devoid of life without even oxygen to breathe, so those who weren't at least Law Masters would be unable to live there.
Moreover, the whole area belonged to the faction of Yale's parents, and given the standing of Yale's mother, which was known by almost all the Origin Gods, no one had the guts to try to conquer an area belonging to the faction.
Of course, the enemies of the universe and those misled by them still tried to do it, but those who attacked were all quite weak showing that the higher-ups didn't dare to launch an all-out attack for fear of a crazy retaliation.
Although both parties were at odds with each other, neither wanted to die, so they wouldn't throw their lives away easily. Of course, that only took into account the strong ones because the weak ones were sacrificed without too much problem.
However, if one of them were to attack the living place of the other party with a full force even if the attack succeeded and killed the descendants of their enemies, the ones who suffered a loss had high chances of going berserk to kill everyone without caring for their own lives.
Yale's mother already provoked a huge mess because her son was cursed before being born and Yale's father provoked serious damages and pinned down the main forces of the ones who forced his son to reincarnate.
However, neither of those happening had been truly lethal for their son, and they already went crazy, so it was easy to think how they would react if they were to send an Origin God to kill Yale.
Moreover, from the other universe point of view, Yale had potential because he was the son of his parents, but the higher-ups had never considered him a threat, so they wouldn't bother to deal with him themselves.
However, they might think again about the topic if they discovered about Yale's Celestial Knowledge, so Yale didn't want to use it in public after having left his world unless there wasn't any other option because he knew that it would be bad if experts of the other universe or their allies discovered it.
Of course, if the matter about the knowledge he obtained from a higher universe was leaked, the other party wouldn't worry about the consequences and would give their all to kill Yale.
After all, the other party never used anyone stronger than a Law God to enter the area of the universe belonging to Yale's parents, but if they had sent a single World God, Yale would have been finished a long time ago even if Lina and Shiba helped him.
In fact, those who attacked Yale's world were just from an allied faction of the invader experts of the other universe, so they already did a lot when they sent their people with some allies to conquer Yale's world.
Most of those who attacked didn't even know that the experts of other universe were in the shadows and were just convinced by their allies, so the matter couldn't be related with the other universe at least openly.
"This is the last dead world before leaving the area belonging to my parents. Let's rest here before continuing."
Yale sent a divine sense message to the others and quickly flew towards the world.
The dead world didn't have anything in it, but it was still acceptable as a place to rest after having traveled a lot of distance without stopping.
After all, it wasn't good to rest in the midst of the space, so those dead worlds were created just to serve to temporally stops when Yale wanted to leave the world.
In his past life, Yale left the world while being far weaker than he was at that moment, so he had needed to use more dead worlds to rest.
It was quite normal in the universe having a lot of dead worlds to serve as a temporally rest place, but it was strange that someone constructed a building or tried to do business despite being some dead planets with a lot of people steeping in them.
After all, no one was willing to live in a dead world for a long time even if the business was good. Moreover, no one dared to claim the dead planets for themselves, so if they tried to monopolize a dead planet, they had high chances of being killed by displeased experts.
After stepping in the dead planet, the four of them entered into the Storage Space.
Although it was possible to enter private dimensions in the midst of the space, it was possible that after leaving, the original position had changed a lot, so it was better to avoid doing such a thing.
Once they depart from the area belonging to Yale's parents, everything would be more dangerous.
They would only enter in dead planets, planets that weren't perfect to avoid someone from using the World's Authority against them, or ownerless planets, but even with those precautions, traveling through the space was still dangerous if one were to have bad luck.
