Rebuilding the Underworld God of Hades

Once upon a time, Lin Musen had seen a statement like this, saying that a scientist had studied that the weight of the soul was 21 grams. Regarding this statement, Lin Musen has not had any opinion in the past 22 years. He is just following what others say. After Lin Musen died, he obtained the Hades system, reorganized the underworld step by step, and ascended to the position of Hades.
