Starts out good but goes downhill from there.
First world is good he fights hard, he gives his all and he earns more because of it.
after that its just relying on cheat and some past accumulations to grow.
The use of his own resources is poor.
Small spoilers after this point:
He is a cancer scientist in his first life, and through that he learns how body, genes and all that work.
but here we see that after that its as if he has no such knowledge at all, he becomes another cheat based fight and concur the world junkie.
Then we are seeing by his third world he is starting to accumulate a harem as well.
Just idiotism.
Those who are new, kinda-new might like this, but those who have been reading a long time, this might not be that likable.
