The demon said: After you die, I will let my demon sons and grandsons wear your cassock and enter your temple to preach my demon theory and corrupt your believers. Buddha replied: At that time, the temple will be the place to imprison your demon son. My disciples will take off their cassocks, put on plain clothes, and go to the world. This Buddha is not that Buddha, this light is not that light, and this walker is not that walker. The title of the book pays homage to "King of Light" = == Book friend group: 3-3-5-4-3-6-0-4-9
