At the same time, it can summon powerful Paladins to assist in battle.] - [Frost Sword Technique: Frost Sword Technique can provide the Warrior's Primordial Spirit with a powerful melee attack ability and reduce the enemy's movement speed.] - [Tale of the Heavenly Book: Tale of the Heavenly Book is a skill book that can be cultivated by the Primordial Spirit of a Taoist priest. It contains powerful healing and defense abilities that can help a Taoist priest better fight against enemies in battle.] Of course, different skill books also have different difficulty and effects. The warrior primordial spirit and the Taoist primordial spirit can choose the most suitable skill book for their own cultivation according to their own preferences and combat needs.
