This is a story with two lines. One wants to become an immortal but cannot, and the other can become an immortal but does not. It is unexpected but reasonable~
Originally it is a rootless stone, it drifts into the mortal world and takes root on the ground. It floats like a dream, lingering on the mortal world and never returning to heaven.
One is ridiculously lazy, the other is ridiculously active
