At his youngest age, around eighteen, he had created the whole power system. The scale of the world was one that could rival even the best at the time. Not only did he manage to create all that, he also created a life system named REBOOT.
Unlike any reincarnation, this reboot system had a precise role in life-and-death situations.
When someone died in the world he created, they didn't actually die. The core concept was that by doing something the gods themselves couldn't do due to their inability to be able to enter the Etherlamentia, the person would be able to continue their life.
The reboot happened only once a year. Not only was it super rare, it was also complex. Every year, dead people from different universes simply converge into this world.
Chances are that no one survives the end of the divine broadcast's channel.
Each of those people would fall under a path. The problem lies here: monitoring Etherlamenthia, the soul world, and every part of it was the gods' duty.
As to the new souls that came each year, it wasn't so profound as to say they all came here willingly. Most came thinking they would be reincarnated with their memories intact. In fact, a maximum of ten people would retain memories; the others would not even be alive in any meaningful sense.
In the end, PSI had come up with an idea to make it like a movie even the myth gods could watch.
At the time he created it, he was a fan of a reality dating show named Love Island, which gave him the idea — why not recap their journeys and serialize it to the gods?
So the reboot actually used dead people, forcefully keeping them alive by a coma, using them as powerful vessels who would monitor each and everything about this new soul show.
There was unfair treatment even among the gods who created this. The system applied only to Guidanceer souls, not the participants. But even though there was no rule saying participants couldn't handle a system, the market of power favored the gods.
Every myth god paid coins to the Guidanceers by giving them powerful artifacts and clothes to wear.
The myth gods loved it when participants used their artifacts and outfits, because those items would help with cultivation later. The more participants used their power on those artifacts and outfits, the more it helped the myth gods become powerful beings.
Every Guidanceer had already been paid coins for it, but each of them had been given so many artifacts and outfits to hand out to participants. Unfortunately, participants would usually choose from only one myth god's collection — the one who paid the most.
Hope this helps.
