ELIXIR OF LIFE
When a guard in his palace stole the elixir of life that was presented by a courtier, the king of Chu was so enraged that he ordered him to be put to death. ???
The guard pleaded with him. “Your Majesty, if what I took was really the elixir of life, I cannot be killed. But if I should die, it would prove the elixir was a fake. That would mean Your Majesty will have killed an innocent man because you have been cheated by somebody else.” ???
The king spared his life.
