To prevent the Heaven-Slaying Weapon from turning into a consumable, and to integrate the Oblivion force normally, one must find a way to expand the weapon's endurance limit or accelerate the weapon's self-repair speed.
However, they had already pushed the repair effect brought by the Vermilion Bird's Spirit to the limit, and to further enhance it, they had to find a way to expand the materials of the Heaven-Slaying Weapon.
The problem is that they don't have suitable materials for expansion.
Currently, the best material the Boundary Breaking Organization has is Yu Heng. Her pure power infused into the Sword Bone ensures that the weapon can withstand the influence of Oblivion, even if the resistance is temporary, it's enough.
