The Soul-consuming Emperor Flame, one of the twelve Sovereign Flames owned by Xiao Chen in his previous life, was also the most powerful among them. Although it hadn't manifested a Fire Spirit, it had already birthed a faint will and would only recognize Xiao Chen as its master.
When Xiao Chen first attempted to break through the heavens, seeking a higher realm beyond the Immortal Realm, he encountered a mysterious force's attack and his physical body died.
He had thought that the Soul-consuming Emperor Flame should have been extinguished under that attack, but unexpectedly, the Soul-consuming Emperor Flame continued to exist and returned to the depths of the Pill Tower.
In fact, the Soul-consuming Emperor Flame had always existed at the bottom of the Pill Tower, being one of the Pill Tower's pillar treasures, and for a hundred thousand years, no one had been able to tame it.
It wasn't until Xiao Chen appeared that the Soul-consuming Emperor Flame submitted to him.
