Unravel the Three Corpses

The crazy old Taoist has been singing Taoist songs on the cliff for thirty years, and everyone in the world laughs at his nonsense. Until the last alchemy furnace of the Baishan Dynasty went out, the emperor died suddenly when the furnace exploded, and the rebels captured Shenjing. I dug out the book "Unraveling the Three Corpses" from the cave, only to realize that every line of the old Taoist's ballad was a prophecy for the death of this rotten dynasty. The elixir is divided into nine turns, and each turn represents a major calamity. The old Taoist sings the ninth turn. It is also the first step to becoming an immortal.
