Transmigrated into Warhammer 40K, But I Didn't Cry Out Loud

[Because this is my first time writing a book, the beginning is a little rough, but it gets better later] (ensemble cast)

Lin Fan, who accidentally transmigrated into the world of Warhammer 40K novels, discovers he has a unique ability.

Under the influence of this ability, the Necrontyr-who slew the Old Ones and silenced the stars-can do nothing to him and call him the Subjective One.

Slaanesh tries to corrupt him but cannot, convulsing all over in frustration; Tzeentch sees him as the mortal enemy who will destroy it and constantly lays various traps in an attempt to save itself.

On the eve of Abaddon the Despoiler's impending launch of the 13th Black Crusade, amid the endless flames of war in the dark galaxy, the increasingly fierce battles, and the unbearable casualties, Lin Fan discovers that he is not omnipotent after all-his ability also has limits.

Can he save humanity? Shape a bright future?
