This water spiritual barrier was unlike the defensive shield generated by an external mystic weapon, which required a large amount of mystic energy to activate.
For instance, previously, to increase the defensive shield's effective range in the plaza, it required four mystic cultivators' simultaneous usage of their defensive mystic weapons.
On the other hand, the water spiritual barrier that Qiao Mu now grasped didn't need assistance from any external object.
As long as she had ample spiritual energy, the water spiritual barrier could be as close or far as she wanted. Furthermore, she only needed to consume a minute amount of spiritual energy to maintain its defense for a long period of time.
Compared with the large-scale defensive boundary, this was naturally more flexible and versatile, and it also consumed less energy.
