Chapter 1578: Mutation of Gold Sage and Silver Sage

"Come out..." Yun Zhongzi uttered as he pinched his fingers while a shrewd light flashed across his eyes. At the same time, light and shadow of All-spirits Tower loomed on his forehead. He then pointed at the two snakes, which then instantly became still in the air. After that, a pentagon loomed on the two snakes' skin. 

There were sophisticated and mysterious geometric grains in the pentagons, including fish scale, claw, feather and horn. Being integrated with the pentagons, these mysterious grains formed the fundamental bloody seal of each one's All-spirits Tower. In Great Wilderness Sect, the fundamental bloody seal was like a unique symbol of each disciple, which would be used when executing many secret methods of Great Wilderness Sect.

While giving out scarlet light, the fundamental bloody seal in the All-spirits Tower slowly came out of the two snakes' bodies and showed its completeness.
