Former mercenary Xiao Fan was betrayed and on the verge of death, and was accidentally bound to the wanted order system of the world - killing the wanted criminals can rob him of his bloodline and origin, and his strength will skyrocket. He brings the "Eye of the Abyss" (to see through illusions but requires devouring energy to suppress backlash) to fight against the Entropic Ember Council that controls the heavens (Cthulhu creatures use the "Anchor of Destiny" to change history).
He used sabers and sniper rifles to carry out decapitation tactics, but he did not know that the system AI Zero had hidden ancient secrets, nor did he realize that he was becoming the "perfect container" in the eyes of the parliament.
