[Multiple heroines] [Honor of Kings]
Lin Yi transmigrates to the Honor of Kings continent and becomes Chang'an City's infamous useless playboy heir.
His parents have died, his family's fortune is gone, and his only redeeming quality is that his childhood friend, Yun Ying, hasn't given up on him.
After awakening the Deep Affection System, he learns that he must build affection with all the female heroes to survive in this world.
And so, he sets off down the path of a scumbag (crossed out), a man who loves everyone.
“I'm not a scumbag,” Lin Yi says solemnly. “I am Chang'an's most devoted man.”
Yun Ying stands behind him with her spear. Gongsun Li folds up her paper umbrella, while Hua Mulan rests a hand on her sword...
“...All right, maybe I am.”
It's good, please update soon! I hope you don't leave it unfinished.
It doesn't quite fit the background story of Honor of Kings; it feels like an alternate world story wrapped in the Honor of Kings skin. Every hero uses a gun, even Mulan and Xiaoman have switched to using guns.
