"The most shocking thing is that a stone coffin was placed at the place where the throne should have been placed. According to the records of the demon sealing Emperor, the treasure that could greatly increase his power was in the stone coffin. However, the Emperor had repeatedly warned him that the treasure in the stone coffin could increase one's power, but it could also cause eternal damnation, and even cause the entire heaven domain and all living beings in the world to suffer.
