The Other World: All My Group Members are 3D Female Protagonists

Li Yijie unexpectedly reincarnated and lived for more than ten years before discovering that he had transmigrated into the world of a Korean comic and become the protagonist in the world of the senior student in the club.
I thought my daily routine would mostly consist of flirting with my female classmates, but while playing games with the succubus professor, I discovered the Underworld Chat Group System!
I started as the group leader and even got an exclusive talent - Demon Card!
Selling demon cards can yield all sorts of treasures from the dimensional world!
And so, Li Yijie went on a killing spree here!
As the only man in the group, he was surprised to discover that his group members all came from the world of adult games and the underworld.
