Chapter 78: Crumbling Decay, Dew Spreads Everywhere
Rikoku Cultivators have the "Sword Flight" technique, and sorcerers also possess a similar spell, called "Krahang".
As of now, the Privy Council hasn't provided an accurate translation, but it is known that it involves a Yin sorcerer activating a spell to command a certain type of Yin ghost to lie on a comrade's back, which enables them to be as light as a feather and take off from the ground, where they pass, there's always a burst of cold wind—In a previous life, Rikoku called this spell "Ghost Walking Technique".
The weakness of the Ghost Walking Technique is quite obvious. For instance, the sorcerer who is possessed can't control their flight, as the possessing Yin ghost's movement only follows the commands of the Yin sorcerer. Some sorcerers cleverly use large fans to try to influence the direction of their flight, but it's actually not very effective.
