As ten dazzling patterns of light lit up, an extraordinarily powerful aura erupted from Xiao Yan's body like a giant dragon awakening. Even the surrounding space collapsed outright beneath that terrifying pressure, a clear sign of how formidable his aura had become!
"How is this possible?" Sensing the pressure Xiao Yan now unleashed, Heavenly Demon Emperor Slaying Heaven's smile faded considerably. He could feel that Xiao Yan's aura had undergone a tremendous leap compared to before!
Although the Great Thousand World possessed certain Secret Arts that could temporarily increase one's strength, their effects were extremely limited, especially those that could work at the Heavenly Sovereign level. Yet what Xiao Yan displayed now undoubtedly overturned everything they knew!
"What terrifying power..." Feeling the immense power surging through him, and the stabbing pain it brought as it coursed through his body, Xiao Yan could not help drawing a deep breath. Had his physique not far surpassed that of others at his level, and had he not had the Fortune Green Lotus's help, this terrifying power would likely have burst him apart already.
Such a terrifying increase came from Xiao Yan's Spirit Vein Divine Ability. Generally, the development of a Spirit Vein Divine Ability was closely tied to the cultivation method its wielder practiced. The Flame Mantra Xiao Yan cultivated, however, was the most wondrous cultivation method under heaven, while his Ten Divine Veins were also the first of their kind in the Great Thousand World. Only the combination of the two could have produced a Divine Ability as outrageously powerful as the Firmament Transformation.
The Firmament Transformation was not a Spirit Vein Divine Ability that attacked directly. Its effects closely resembled those of the Heavenly Fire Three Mysterious Transformations he had once used on the Dou Qi Continent, only far more powerful.
