The sky and the earth are dark and yellow, the universe is vast, the sun and the moon are flat, and the morning and night are spread out.
When a person's Yang life has expired, he will be taken to the underworld by Yin to judge his merits and demerits, and be reincarnated.
And those ghosts who are unwilling to leave due to unfinished business will stay in the underworld and be forced to take exams!
Motto: Everything has a cause and effect
