Chapter 572: Chapter 497: Professor Cui_2

But a second later, Yang Xiao noticed a trend in the light fading. The spiritual power maintaining the Ghost Lantern was being drawn away by the opposite side. The speed of extraction was neither fast nor slow, just equal to his input. Simultaneously, a sound of "whoosh whoosh" water echoed near Yang Xiao's ears.

Based on his own feelings, the opposing magic artifact was likely a water bottle or something of a teapot, exactly the thing extracting his spiritual power.

"No, continue." Professor Cui's tone had changed from before.
