Detective Conan: The Rich Lady Loves Fine Wine, Money, and Beautiful Women

[A morally complex heroine, revenge, multiple male leads]

(Not having read the original won't stop you from enjoying this.)

Mei Xianya Ying transmigrates into the world of Detective Conan.

Unfamiliar with the plot, she assumes everything here is perfectly normal,

and races headlong toward becoming a business tycoon, armed with her knowledge of the future.

That is, until she discovers someone researching a way to reverse aging.

What? Is this still science?

Even worse, a transnational crime syndicate has set its sights on her...

(I originally wanted to write a romance-focused story, but somehow the plot kept growing as I wrote.)
