Congratulations, Host, you’ve obtained an item: 【Bloodline Card: Kryptonian Bloodline (Optimized)】.” “Ding! Congratulations, Host, you’ve obtained an item: 【Chaos Supreme Treasure: Green Lotus of Creation】.” Yun Kong accidentally transmigrates to the world of Naruto and gains a golden finger that lets him sign in across the Myriad Worlds. And so begins his troublemaking journey across the worlds! Naruto: Uchiha Madara, didn’t you want to dance? Come on, give us a show. Demon Slayer: Muzan, you look awfully pale.

World of Warcraft: Sargeras, hurry up and invade! I’m running low on fel energy and desperately need a demon-powered battery.
