Liu Ye, a child raised in a ghost village, has his own filter of "truth, goodness and beauty" and can regard all weird things as beautiful things. He regarded the ghost soup as a tonic soup and forced "Mom" to drink it; he regarded the ghost as a little cutie and force-fed him milk to replenish his body. This special skill allowed him to live like a "devil boy" in the world of ghosts and monsters. After accidentally hitting a lot of weird things and severely damaging them, the ghosts in the whole village wanted to lose everything and send him to the outside world.
