One-Halved Superman: Warhammer Gray Knight, Comes to the World

When the horror works and strange legends of the 21st century have become a hotbed of blasphemy and pollution, Shining Armor's demon-killing blade travels through time and space and comes to the world! He is a Gray Knight with powerful psychic powers, a flawless soul and absolute loyalty! He travels through the indulgent fantasies of urban humans, smashing all fears with ultimate violence! On the surface, he is a contrasting cute "coser" guy, but in fact he is the nemesis of all demons in the shadow world/human world! Let these ghosts and monsters taste the iron halberd from forty thousand years in the future! [Modern urban background, just understand the basic concepts of Warhammer 40K] [The famous protagonist is invincible, and finally becomes a god driven by the super long-term plot]
