I can't remember name of this novel but I want to re-read it again. It's probably quick transmigration or rebirth novel. Protagonist is a scientist and he is working in research center where they research people with abilities. ML is special specimen who was asleep but woke up when protagonist came to this world. He later was coming to MC in night (when he was sleeping?) and was harassing him. Later people who have special abilities ran away and created their own organization. And ML took MC with them. Oh, and there was also some girl -she was main mission of MC... I think. Sorry for the bad grammar.
But there was nothing about a girl there, nor did they research abilities Definitely no harassment I was thinking that this is perhaps perfect destiny however the one being the scientist is the the there
It's not it. I don't remember a lot of that but I don't think it was zombie world, they were people with special abilities and they were doing experiments on them (rest of the world don't know about these people untill they ran away). And I think MC has to change fate of girl who was one of people with abilities.
