Zi Zhou or Shou is the father of Wu Geng and the emperor of the Shang dynasty. Powerful and mighty he is one of the few mortals who can challenge the gods and dare them to unleash their wrath on him. He is also the wielder of the legendary armor Immortal Phoenix, a divine beast which resides within the suit of the armor. It absorbs the life force of the wielder but it grants amazing skills and power. He was fighting very good against three gods single handedly while he was wearing the armor.
Tian is one of the strongest gods in the series and he killed Zi Shou. Zhou though fought bravely until his final moments against Tian.
