Additionally, Su Lin felt that his cervical vertebrae, through the numerous occasions of absorbing the Thundercloud Power, were once again fermenting Mystic Bones.
It was just that the energy required for these Mystic Bones was significantly greater than ever before—as if a bottomless pit.
Even after absorbing so much Pure Energy and Rule Power, it was still not enough to successfully shape them.
However, Su Lin was not discouraged in the slightest, his expression instead grew excited.
This was because the difficulty in shaping Mystic Bones and their power has always been proportional.
Mystic Bones that require such a massive amount of top-level rules and energy to shape, the secret techniques they give birth to, would also far surpass Bewildering Step and Soul Requiem.
Perhaps they could be like the Soul Devouring Demon's Soul Codex or the Godspeed Golden Eagle's Yin Yang Nine Transformation, which are supreme secret techniques capable of defeating stronger opponents.
