Inside the gate, Kai and Xiaozen stood silent for a few moments before Kai walked towards the lake and reached knee-deep inside the golden-colored water.
His clothes started sizzling as they burned away till his knees. Xiaozen watched it with an expected reaction as she put the staff down.
Kai then started walking even further as all of his clothes slowly started burning until he was standing naked in the lake. The golden water swirled arounnd him and covered him till his shoulders as he closed his eyes in concentration.
The yang energy in the lake water was powerful enough to incinerate a person alive if they lost their focus for a second so Kai kept his eyes closed as he took out the spiritual core containing ten percent of the original spiritual energy.
