Fang Mu was still somewhat surprised by Yun He's rapid energy level enhancement.
The increase in energy level granted Yun He new skills and exclusive properties, essentially adding more combat techniques to Yun He's arsenal.
The skill Yun He obtained at Platinum Rank, [Elemental Healing], was a healing-type skill that could heal itself as well as its allies.
This skill allowed Yun He to continue aerial combat even if its wings were critically injured.
Such a healing capability greatly enhanced Yun He's resilience and could also provide care for Golan, making it a reasonably dependable healing skill.
This type of healing skill significantly improved the margin for error in combat. Otherwise, Fang Mu would truly have had to specifically search for a unit with healing abilities to support development in the Giant Beast World.
