In this age of time-space chaos, transmigrators and the reborn are everywhere. Spatial powers, Systems, and the kind of golden fingers everyone loves are common as dirt. Anyone you randomly pick out of a crowd who looks good could be a domineering CEO, a yandere, an obsessive, or a hopeless romantic. These people say, “Science has fallen into decline, folks. This is the world of romance web novels now.”
But one day, the M nation, which loves making thrilling Resident Evil films, really did invent a zombie virus. The protagonists all got infected like idiots, and the whole world fell. Then the mad scientist Mo Ran, branded a paranoid yandere with no parents and a big villain destined to be a stepping stone for the protagonist, finally rose to the occasion and became humanity's savior. He used loopholes in spacetime to change humanity's fate again and again. To do so, he even sacrificed his dignity to seduce Zero, a child a thousand years younger than him, and make him work for him.
By the time Zero finally understood that Mo Ran had been using him, Mo Ran had already achieved his goal and returned to his hometown on Blue Star with years of research in hand, ready to retire.
(HE, no female lead, the pursued “top” gets his comeuppance.)
