Duan Yun and Shen Ying used gold to buy the identities of two "Lords of Heaven".
It is often said that the identity of a Lord of Heaven is priceless, worth more than a Gold Mountain and Silver Mountain, but that's because the price offered is never high enough.
The most famous example is a heavenly person named Chang Ziru, who claimed that being a Lord of Heaven was the ultimate happiness.
He served a Daoist of the Heavenly Human Dao, and naturally, he praised this Daoist to the heavens, often saying he never asked for any reward, only wanting to be close to the Daoist, being able to see him practice alchemy and martial arts every day. Even simply serving the Daoist while he relieved himself was a form of happiness.
But later, when another Daoist enticed him, he still ran off.
