Su Xiao examined the Plant Harmonization chapter of Alchemy. During the previous Battle of the Strong, he had unlocked a new recipe called "Life of the Tree."
Life of the Tree: Each preparation required 1,300 Mana and consumed the following materials: Bewitched Flame Wood Core, Soul Crystal (Small) ×1, Wood-element Life Essence, Water of Revival, and Crystal Bottle.

He had only five chances. Su Xiao prepared
