"Killing Life" was a form created by An Jing through the condensation of Qi into a weapon, imbued with a nascent consciousness. It possessed the sharpness of Great White and contained a complex, intricate sword aura; once one was struck, the wound was notoriously difficult to heal. Even if one managed to force a recovery, it would consume several times the time and energy of a normal wound.
And "Decree of Tribulation" was an ability An Jing bestowed using the Great White Divine Ability. Built upon the foundation of Killing Life, it was further reinforced by "Piercing White Rainbow" and "Wielding the Heavenly Time." Its speed was like thunder, its force weighed a thousand jun, and it served as the ultimate piercing Divine Ability—allowing for no person and no thing to stand in its way.
When the two were combined, they resulted in an attack that ignored all defenses and dealt "true damage" that could not be healed—a strike just like a "tribulation," descending from the heavens, impossible to evade.
