Cuckold Wizard's Adventure - Chapter 573 - 562 ‘Corruption’ Magic

Sian Lee, the strongest person under the heavens in old china, was reborn as a very overweight woman.

As soon as she fell into the world of beastmen, a leopard forcibly took her back to his home. Indeed, Bai Qingqing is at a complete and utter loss. The males in this world are all handsome beyond compare, while the women are all so horrid that even the gods shudder at their sight. As a first-rate girl from the modern world (she’s also a quarter Russian), Bai Qingqing finds herself sitting at the center of a harem filled with beautiful men — at the very peak of existence.

This is an alternate history. Decades after the fall of the Eastern Jin Dynasty, the world is still in chaos, although there is hope for reunification.
