With the All-Heaven Weapon in hand, Yu Heng adapted to the specifications of the weapon in the shortest possible time. The weapon's normal state is a sword form, yet it possesses fusion capabilities.
Back then, when Ban Long used this weapon, he didn't use it as a sword but instead directly fused it into himself, treating himself as the Heaven-Slaying Weapon.
However, doing so requires a greater sacrifice. With the sword outside, most of the burden is borne by the weapon; once fused into oneself, it becomes a shared responsibility with the user.
During fusion, the Undying Life Flame of the All-Heaven Weapon can also take effect, but for the user, it still brings substantial harm. If the user's constitution is insufficient, using it this way can quickly lead to death.
