The Sleeping Willow Spirit, apart from being able to sleep and live a long life, has nothing to do with fairies. It also has the talent to slay demons and slaves. However, after thousands of years of inheritance, the habit of dozing off has become extremely rare among tribesmen. However, it has recently been rumored in the Demon Slayer Continent that the inner elixir of the Sleeping Tree Spirit can rewind time, and family rituals have long predicted that the family will be destroyed.
