He found out that he is in a world similar to our own with a timeline akin to early twentieth century.

A handsome man was hit and lost his memory for dangerous driving and saved by Lin Xiaomi. Since the day, the man just hung on in her house and refused to clear out. Also, from that day on, the only goal of Lin Xiaomi was to dislodge him!

The first person that Leng Yihuang saw after losing memory was Lin Xiaomi, who was a full-breasted beauty simple like an innocent child. She fascinated Leng Yihuang like a magnet. Since the day they met, his only thought was to f*ck her!

Of course, the winner is king, the loser needed to warm the bed… But after the night, the bastard just disappeared. Lin Xiaomi swore to God that she would hunt down that as*hole no matter where he was.

But when a bunch of guards with guns showed up and called Lin Xiaomi “Your Ladyship”, she was struck dumb with fear and astonishment. The man who walked out of a Rolls-Royce was just Leng Yihuang, who turned out to be the heir of a big shot…
