The Small Revival Spell is quite straightforward. It's a recovery spell. The result of the spell is very limited, as demonstrated by a young boy earlier, only able to accelerate the healing of injuries.
Worth mentioning is the Spring Rain Technique. The effect of this spell is not too dissimilar from the Rain Summoning Technique, as both involve summoning rain.
However, in comparison to the Rain Summoning Technique, the Spring Rain Technique covers a larger area, and the rain it brings is not ordinary rain. It consists of droplets saturated with a faint amount of Spirit Energy, which can nourish the earth and accelerate plant growth.
Due to Dong Tianyu's continued practice of the Spring Rain Technique, the once brown slopes of Nameless Mountain began to show signs of green, undeterminable seeds buried within the soil began to sprout.
