Legend has it that the cat demon has a tenth tail above the nine tails, and humans will have a new realm above the immortal fate.
Those who practice Taoism with love cut off their worldly ties, and those who aim at the Ten-Tails cut off the Nine-Tails themselves.
In life, if you don't have some emotions and desires, you can't live it. You can't feel comfortable if you are trapped in it.
Whether it's an immortal or a demon, you can't be a human being or a ghost.
Purpose: Living without obsession is not considered living, and having obsession is not considered being at ease.
