The Water-Fire Staff is a fifth-tier magical weapon, which theoretically can only be perfectly wielded by cultivators who have reached the Spiritual Infant Realm.

For those whose cultivation hasn't reached the Spiritual Infant Realm, forcibly using it would only lead to the weapon going berserk.

However, Ye Tian, who has mastered the "Mastery of a Hundred Weapons," can surpass his level and forcibly activate it with his Spiritual Core Realm cultivation.

He can't sustain it for long, only about the time it takes for half an incense stick to burn.
