One has to admit, Cheng Sheng's transformation into the Golden Arhat was genuinely surprising to Zhou Yu.
Previously, when the old man taught him martial arts, he once mentioned it.
Some Body Refining Techniques have the effect of transformation.
Any Body Refining Technique that allows transformation is one of the most authentic methods passed down from Ancient Times, and such techniques often possess unfathomable power.
The Golden Cauldron Technique Zhou Yu acquired, when cultivated to the Ninth Rank Extreme Realm, actually causes his skin to become entirely like the texture of a golden cauldron, somewhat similar to Cheng Sheng's current appearance.
It is estimated that the original Golden Cauldron Technique likely had a similar transformation effect.
However, the Golden Cauldron Technique that Zhou Yu cultivated lacked the transformation effect because the latter part of the technique was something Zhou Yu had to explore and cultivate on his own.
