Lin Waner's life has two scripts. In the A-side script, she is the last descendant of the Valley of Divine Doctors. She hangs a pot to help the world, and her smile is more compassionate than the Bodhisattva. People give her the nickname "Living Bodhisattva".

He always dealt with her after she committed a murder, and gently comforted her when she was shaken: "Wan'er, don't be afraid, I have everything under my control." She once thought that her senior brother was the only light in her dark world. Until the end, she fed herself with poison, narrowly escaped death, and finally lured out the poisonous snake. When she saw the man's face clearly under the mask, she smiled, and her smile was uglier than crying. It turns out that that beam of light is the deepest darkness.
