With the strongest experts from the 33 Skies the Human Emperor, Lin Ming, and his opponent, the Abyssal Demon King, were embroiled in a final battle. In the end, the Human Emperor destroyed the Abyssal World and killed the Abyssal Demon King. By then, a godly artifact, the mysterious purple card that had previously sealed the Abyssal Demon King, had long since disappeared into the space-time vortex, tunneling through infinite spacetime together with one of Lin Ming’s loved ones. In the vast wilderness, where martial arts was still slowly growing in its infancy, several peerless masters tried to find their path in the world of martial arts. A young adult named Yi Yun from modern Earth unwittingly stumbles into such a world and begins his journey with a purple card of unknown origin. This is a magnificent yet unknown true martial world! This is the story of a normal young adult and his adventures!!
The Blood King's possession of the Ancestor God's blood was his secret to begin with.
Yi Yun came from the Tian Yuan world and having heard Jiang Xiaorou's description of the Blood King's growth, he surmised that the Blood King might possess the Ancestor God's blood.
It was unlikely the Ruins Emperor knew of the secret.
However, when Yi Yun's pills were formed, the phenomena which resulted included a scene of Human, Fey, and Celestial fusion despite it lasting only for a few seconds.
However, it was likely that the Ruins Emperor had noticed something from the auras of the phenomena. He had likely seen the Ancestor God's blood before and because of that, he could sense the Ancestor God's aura from the phenomena!
If the Ruins Emperor could tell, it was likely the other two patriarchs did as well!
