Even though Jia Yan kept insisting he didn't want to absorb any more soil from the ground, his body continued to crazily take in soil and other substances from the earth. Perhaps, even Jia Yan himself hadn't realised that his mutation wasn't simply powered by a single superior mutating material; every mutating substance, every kind of matter, mattered in the process!
If he lacked certain substances commonly found in soil, his mutation would not be perfect. Even if he purely used the best mutating material, the effect wouldn't good using just that. Instead, Jia Yan's body was simply following its instinct, absorbing all useful materials into its body and aiding his mutation process!
The main substances essential for his mutation is, of course, the green-grey pebble and metallic elements. These two things ensured the success of his mutation and will be the foundation of his future power. As for the other auxiliary substances, they seemed rather irrelevant at this stage!
