Yin Wuji, the tyrant of the Great Xia, slaughtered all loyal people three years after he ascended the throne, built a star observatory with human bones, and watered the immortality flower with his blood. He set up a snake cave to execute remonstrators, ordered the people to report each other, and burned three thousand boys and girls overnight to seek elixirs. The anger of the sky brought drought, but he smiled and said: "Does an ant deserve to ask for rain?" When the rebel army invaded the imperial city, he was using the heads of loyal ministers as drinking vessels, and while he was drinking, his favorite demon concubine pierced his heart with her own hands. Before he died, he still yelled: "I am destined by fate!" - Historic books record 200 crimes. Thousands of people dug up graves and whipped corpses, leaving only a finger bone that could not be melted away. He cried like a baby every night.
