In the era when the gods fell, the cursed Broken Throne finally waited for its last owner - an amnesiac boy who walked out of the slums. The moment he touched the remains of the throne, the ancient prophecy began to flow: the seven keys will recast the crown, and the holder will become the only variable in destroying the world or saving all living beings. At this moment, the old ruler who had been dormant for thousands of years opened his eyes. The imperial cavalry crushed the last dawn of the border, and the first key in the young man's hand was emitting a blazing light that pierced destiny.
