My Dream Is Reincarnation in the Ghost World

Eighteen years ago, Weirdness came to the world, which coincided with his birth, and he became an orphan in his infancy. The world relies on exercises, instruments and ancient artifacts to fight evil spirits, but he will fall asleep for no reason and fall into the dreamland of reincarnation composed of seven emotions and six desires. Thousands of reincarnations of life and death have refined his soul. Others regard him as a useless person, but they don't know that he has long been free of distracting thoughts and is invulnerable to all conspiracies.
