MTL - Allure of the World - Chapter 73 strange disease

Xue Xi is forced to fall in love at first sight with this dangerous man on their first meeting. With death being the only other option, she makes the first move:

Roan transmigrated as an FBI investigator.Several years later, a journalist interviewed the world-renowned detective Roan Greenwood and asked,“What made you persist in solving cases for so many years?”Roan tilted his head and glanced at the sports car beside him, the villa behind him, and the beautiful woman inside the villa. He smiled slightly and said,“Well, the bonus after solving the case.”“What?”

He doesn’t just tame beasts—he conquers everything.Nothing is off-limits to Rex. Beasts. Humans. Gods. Artifacts. If it has a will, it belongs to him.

When the system warned the world that it was coming a week in advance, Alex couldn’t have been more excited. In college for a degree he didn’t care about to get a job he didn’t want, the promise of a world where magic and challenge awaited — even at the potential cost of death — was the best news he possibly could have imagined. Alex was ready for a new life. He ready for his only friend to shove him through a portal into hell the moment the apocalypse started. Instead of getting to punt rabbits and farm wolves, Alex finds himself stranded in a warped world where even the bugs are stronger than he is. Even with a summoner class that gains the powers of its monsters, most people would have died. Alex didn’t get the memo. He might have liked challenge a little bit too much. Where others saw certain death, he found something else. Opportunity.
