I'm a Drifter on the Streets of the Universe

[Mostly original plot + Ultraman fanfiction + Ultraman Mother as the heroine] Lin En accidentally transmigrates through a wormhole and arrives in the Land of Light, where he witnesses the Plasma Spark Tower being ignited. He meets Mary (Ultraman Mother), and in the years that follow, they have a son, Lin Kai. Lin Kai grows up alongside Taro and meets Tregear. (I might not write Tregear’s corruption, but I’m still unsure whether to include it.) They go through one war after another and defeat one powerful enemy after the next: the Alien Empera, the Great Demon King Juda, the Spark Wars with Lugiel, Mega Monster Battle: Ultra Galaxy Legends, the Belial Galactic Empire, the Zero Gaiden, Ultra Zero Fight, Galaxy Fight, and the QQ life-form Tartarus.
