The Return of Zhang Tie's Power

Under the gaze of Zhang Tie and Yun Zhongzi, the two boas constantly cast off their scales. As a result, the entire sage's realm became a huge colorful egg reflected by various colorful lights. When the two snakes completely cast off their skins, the hundreds of meters long skins burned up in the sky, turning into colorful four elements before dispersing in the sky. Such a scene was really like a doomsday. 

Besides having new skins and scales, the two snakes had two evidently bulged horns on their heads. In addition, Zhang Tie noticed that the two snakes changed their way of movement. Previously, the two snakes moved forward by twisting their bodies left and right; now, they started to twist up and down.

Unless being blind, everyone knew that they were evolving. 

"Aah, that's unbelievable..." Yun Zhongzi was stunned as he murmured facing the flying fiery rain of four elements and the extremely brilliant golden and silver lights.
