[Multiple female leads] [Invincible protagonist] [Pure and satisfying] [Non-Japanese male lead]

Lu Ming, from the world of high martial arts, obtains a system that allows him to travel to anime worlds. He can obtain different rewards by conquering these worlds.

However, these anime seem to be somewhat niche...

For example, "About My Brother and I Living Together in a Small Town."

Or, "My Devil Club Story is Really Problematic"

Or perhaps, "The Story of the Tsundere Student Council President and His Naturally Dark Twin Sisters"

I will always love Eriri Sawamura, Megumi Kato, and Utaha Kasumigaoka. *Slap*— Is that what you call liking? You're just lusting after their bodies! You... *Slap*—(slaps back) So what if I lust after their bodies?! You have to live your life clearly, know what you want to do, and be honest! (Crossover anime worlds, tentatively: How to Raise a Boring Girlfriend, My Youth Romantic Comedy Is Wrong As Expected, You're the Only One Who Likes Me, School Days, Sword Art Online, Black Bullet, Ultraman Tiga, Dragon Ball... and some other strange and wonderful things.)
