Three thousand years later, powerful human beings created six temples in order to combine human strength. As time went by, the magicians who were once prosperous gradually withered away. The bodies of rare elements have not been produced for thousands of years. The magic temple has also become the second thousand-year-old among the six temples! Until one day thousands of years later, all the elements in the Tower of the Magic Temple God were shrouded in darkness, and the surviving dark magic god awakened and headed straight for the southern border of the Temple Alliance! Only an old voice was left, echoing at the top of the Tower of God! "Three thousand years have passed, and the Son of Darkness finally appears!" ... Assassin's Temple.
