In this world, showing just levels was not good enough to prove someone's strength. That was because of the power system that this world had.
In this power system, it was possible for a true powerhouse to carry someone and increase their levels without that fake powerhouses doing anything and having no powers. There had been many cases like that in this world.
According to one of the famous incidents, a level 6000 plus powerhouse, who was supposed to be one of the strongest of this world, he was very easily defeated by a level 4000 plus powerhouse who was a from a different world and had a different power system.
That was extremely humiliating for a divine grade world like this. So a large scale investigation was conducted and it was found out that this level 6000 plus powerhouse was a relative of a level 7000 plus super power of this world.
