"Chaos Staff," a relic of the Progenitors as spoken of in legends, had been refined over the years by this "Aztec" Immortal. In his eyes, it was nothing short of a divine artifact. To better control Su Yu—and even to monitor his every move—this Immortal entity had left the "Chaos Staff" by Su Yu's side.
But he never anticipated that Su Yu would be so audacious as to eye the "Chaos Staff," intending to devour the power within to make it his own.
Ever since the battle at the Mayan "Bonanpak City," the "Chaos Staff" had stayed in Su Yu's hands. At that time, he hadn't thought of taking control of the staff, but this time, after the Aztec Immortal had left the staff with him and made it clear that he couldn't throw it away, it was obvious that the other party was compelling him to keep it.
