People have always thought that the underworld is lifeless and a dead city with nothing. In fact, the underworld is the same as the human world, and even more prosperous than the human world. The underworld is divided into inaction space and void space. The inaction space is where the people of the underworld live. The "people" here are those who died unjustly in the human world or died unexpectedly in their prime. Once these people enter the underworld, they will forget everything about the human world. The time of the world is the time of reincarnation. Before entering the inaction space, the person must be classified according to the good deeds accumulated during his or her lifetime to determine the person's status in the inaction space. The only difference between the inaction space and the human world is that the people in the inaction space must learn one of the magic, martial arts or spells. When the power reaches B level, they can have an entity. When the power reaches S level, they can go to the void space to serve or play in the human world. The Hades Palace in the void space is the most powerful place in the underworld. The power of every "person" living in it is enough to destroy the heaven and earth. This is also the reason why the underworld can compete with the fairy world. Except for the Hades Palace, the void space is an illusory building. When the people of the inaction space arrive in the void space After a while, if you can crack the illusory world inside, you can enter the Hades Palace to accept the guidance of Hades, guard the Hades Palace, and also have the right to travel to and from all walks of life at will. (Everything in the Hades Palace is free. After entering the Hades Palace, you will no longer be bound by anyone in the Hades except Pluto.
