I transmigrated at the same time and became the King!

This book is also known as, "In One-Punch Man, After Three Years of Hard Work, I'm Invincible!"... Ze Feng transmigrated to the One-Punch Man world, becoming King. He and Saitama endured three years of hardship, breaking through their limits in countless battles and vaguely unlocking humanity's limitations. But three years later, a mechanical notification sounded in Ze Feng's mind; he had been pulled into a dimensional self-help group. To this, Ze Feng could only say, "I've already surpassed Dragon level, what's the use of this broken cheat arriving so late?" However, after entering the dimensional self-help group, Ze Feng discovered that everyone in it was a version of himself from different worlds. [Anime, games, tokusatsu... his shadow can be found in various different worlds.] Shared abilities, shared items, shared transformations, and various buffs stacked multiple times! [Ben10 World Ze Feng: Dude, how did you transmigrate into King, this weakling? I'm sharing this ultimate watch with you, don't suddenly die.] [Naruto World Ze Feng: Dude, you're really unlucky. Even though King's luck is good, he might crash and burn someday. I'm sharing this Rinnegan with you; try your best to survive.] [Ultraman World Ze Feng: Dude, I want to help you too, but I'm still locked up. I don't have anything to share with you. I can only pray you can survive in that One-Punch Man world where Demon-level enemies are as weak as dogs and Dragon-level enemies are everywhere.] Regarding his worries about himself in the other four worlds, Ze Feng, who had transmigrated into King, laughed. Did they really think I was a weakling? I am the undisputed strongest on Earth!!!
