A rusty ring gave me two-way travel. I saved a celestial princess and stole everything from her realm.

A broke Earth guy stumbles into a primeval realm of giant beasts—cows the size of elephants, sparrows bigger than cars. His flea-market ring isn't junk; it lets him travel both ways, devour anything to grow, and even houses a livable pocket dimension. From saving a poisoned celestial sect leader to looting rare herbs, recruiting a goddess, taming a beast-eared spirit girl, and clashing with demon clans—he settles every grudge on the spot, no enemies left breathing overnight. Overpowered MC, multiple female leads, zero filler, all payoff. Yan Feiyu was just a broke renter—until a scratch on his hand bled onto a dusty old ring he'd picked up at a thrift market. Next thing he knew, he was standing in an alien jungle. Oxen as big as elephants. Sparrows the size of sedans. And a pterodactyl chasing down a giant pheasant like it was Tuesday. The ring wasn't junk. It was a legendary treasure—capable of shuttling him between Earth and this other world, consuming any material to evolve, and containing a fully habitable space inside. His first mission? Save a sect leader poisoned with a love-inducing aphrodisiac. That was just the beginning. After that came: • Plundering spirit herbs and beast materials to stock his pocket dimension; • Bringing back modern tech and supplies for a one-sided curb-stomp in the other world; • Building a crew of stunning women—a modern Earth girl, a celestial goddess, a beast-eared spirit clan beauty, and a demon clan princess—with multiple love interests handled cleanly; • Zero tolerance for grudges—every enemy pays, right then and there, with overwhelming force. No grinding. No forced stupidity. The ring is broken, but the MC is even more so. He starts at the top, but "overpowered" doesn't mean "brainless"—every resource grab has a reason, every move lands with precision. If you're into dual-world travel + base-building + harem without the cringe + non-stop satisfying moments, this one's for you.
