By using his Blink at its maximum range, Gu Fei was able to move six meters forward. No matter how turbulent and furious the undercurrent was, it would not be any faster than an instantaneous rematerialization. Gu Fei turned around and brandished his Moonlit Nightfalls as he chanted, "Electric Wall! Fall!"
The description for the Electric Wall spell apparently stated that it was capable of blocking everything. The moment that it came into existence, it was more or less able to cover the whole opening of the dark tunnel. The sparking electricity that the wall created helped shine a bit of light on their surroundings. In a glance, Gu Fei could see that the flow of the water was indeed a little stymied by the wall, though it was quickly losing its spark and dimming over time until the time when the water would eventually completely overwhelm it.
