Transmigrating Through Myriad Worlds from the National Team

The protagonist was an ordinary office worker until an accident gave him the ability to transmigrate through time and space.

On his first trip, he transmigrates to the National Team just to resolve a lingering regret. Later, he'll visit worlds like The Return of the Condor Heroes and other high-martial-arts settings. Once he's grown enough, he'll head to fantasy worlds. For now, I'm thinking of the Douluo, Battle Through the Heavens, and Perfect World trilogies, as well as Jade Dynasty and others. If you have any good ideas, leave me a message. Now, let's step into these anime worlds from the protagonist's perspective and experience all the different adventures!
