To make it short I'm looking for stories which fulfill those criteria.
1. Mc focus only on himself, not others
2. Smart, calm, evil/indifferent personally, any hero traits can go to hell.
3. He don't have any relatives or someone important to him, or as call it burdens. (He can have some friends, but he should be able to sacrifice them for his own benefits)
4. No harem, or love interest, that usually makes Mc act stupid in name of love.
I have already read.
WMW, Merchant of death, Daoist Gu, well only those were ones that I have enjoyed, sadly merchant of death I probably dropped :(
Waiting for suggestions. And don't recommend overlord, because he isn't exactly evil.
