I honestly don't see where this is going. Is he basically just going to murder every guild out there? Seems like it. He's basically has GM power in the game, and anything less than a pure HP% damage skill that pierces defenses isn't going to kill him, and I'm basically assuming at this point that such skills don't exist. He probably has 100% HP regen/second too.
Although, with MAX str, I'm surprised he isn't destroying the ground and buildings. If he is wrong about his strength control (99 trillion according to chapter 1) by even .00001%, that's still a margin of error of 9 million strength. And considering an average human's strength was just 20, he every movement he makes should be destroying cities if he can't control his strength to .0000000001% which is such extreme precision, its at the level of state of the art scientific precision instruments or even beyond that.
But back to the series, I feel the bulk of it is going to be PVP instead of PVM.
