The use of vine confinement primarily involves wood-based spiritual energy and the real vines that are induced. Yi Jue changes this by first using Gang Qi to restrain the enemy, then simulating and transforming into vines, and finally using the induced vines to confine the enemy. There is a process of transitioning from illusion to reality.
This transition from illusion to reality demands high control over spiritual energy, requiring at least a high-rank cultivation level to skillfully master. However, only with such transformation can Yi Jue achieve the goal of fast spellcasting.
Therefore, the Qingmu Prison Cage technique can be considered an upgrade of vine confinement, though the changes are indeed significant. Tiegu regarded it as an ordinary wood-based technique, defending as usual and unexpectedly suffering a hidden loss.
