Bad news: He was destroyed.

Good news: He was not a dump truck, so he is still alive.

Bad news: He failed to travel to another world and start his dream life.

Good news: The mysterious space also destroyed Bai Qi, and his soul was copied countless times. The origin of his soul was broken into two or three pieces, and he traveled to the world of endless dimensions.

The question is, why are all the people he traveled to girls?

Kiana in Honkai Impact 3rd is Bai Qi, and Kiana in Honkai Impact 2nd is Bai Qi.

Kiana (III): Kevin? The End? Trial of Civilization?

Golden wings appeared behind her, and the Honkai Impact 2nd version of the End came. Kiana pointed her gun at Kevin and the End Cocoon behind him: "Look at me and say it again?"

Nishiki Chitsuki is Bai Qi, and Haibara Ai is Bai Qi.

Gin: Ah~! Snow...! ?

Before he finished speaking, Gin looked at Miyano Shiho who was walking in the hail of bullets, and his eyes widened with horror!

Lucy is Bai Qi, and the Mecha-Machina is Bai Qi.

Lucy stood on the top of Arasaka Tower: "Corporate Military Armed Forces, Adam Hammer?"

The Ex-Machina armed forces extended and opened, "You are surrounded by me."

Because the memories of these Baiqi were worn out during the journey, the main personality after the memory was restored still tended to be female.

So... 99 wives, they are all me!
