In fact, there is no need to set up any underworld at all, and the way of heaven can naturally make people reincarnate. This dynasty set up the underworld because of the emperor's selfishness. At that time, the emperor had already comprehended the method of reincarnation in the Heavenly Dao, so he planned to use this method to set up the Difu and cultivate loyal ministers and good generals for himself.

Of course, there is also the cultivation of more and more powerful souls for him to suck and improve to the realm of cultivation, delusional pursuit of the Tao is endless. Even if you can only cultivate to the realm of immortality and never move forward, it will be worth it. Because this is already immortal, it doesn't matter if you can break through or not.

Later, someone in the divine realm saw through the emperor's elaborate layout, exposed his unspeakable and shocking secrets, and let the world know his extremely evil side. Therefore, no matter how powerful the dynasty is, it has to perish under the joint crusade of everyone. That is, since then, among the Three Realms, no dynasty has dared to build an underworld. Because in these three realms, the soul of a person after death has its own Heavenly Dao management, and there is no need for any living beings to interfere more.

The Heavenly Dao can't let the souls of dead beings reincarnate, so naturally no one can do that. Therefore, some souls cannot be reincarnated successfully, but can only merge into the Three Realms and into chaos. It's better than no chance, though.

In addition, those cultivators who have been devoured by the primordial gods, this is not absolutely without a chance of reincarnation, but the chance is small. Even if there is a chance to be reincarnated, it may not be possible to succeed in reincarnation.

The cultivator's primordial spirit is devoured and completely digested, and the cultivator is truly dead. And after death, there will naturally be a soul. However, this soul will be weaker and will hardly be complete. If this soul's luck and essence are not good enough, it will have already dissipated before the Heavenly Dao can manage it. Therefore, the chance of reincarnation is naturally gone. Although some have the opportunity, they are generally not successful in reincarnation.

Of course, there are some people whose Dao methods can completely destroy and absorb the soul of the enemy. Once you die, you don't have a soul, but you are truly and permanently dead, and there is no possibility of reincarnation. The dead creatures have no souls, and the Three Realms Heavenly Dao is helpless, there is no way to let the dead creatures have the opportunity to be reincarnated.

Therefore, after death, ordinary cultivators generally die without a place to be buried, and basically there is no chance of reincarnation. Generally, only those beings who are naturally born, old, sick, and die without cultivation can have the opportunity to be reincarnated, and this is also where the fairness of the Heavenly Dao lies for them. Only in this way can they have a complete soul after they die, and the Heavenly Dao can manage it in time, so that they can be protected from harm and have the opportunity to be reincarnated.

Once it is managed by the Heavenly Dao, there is a 100% chance of being reincarnated. As for whether this can be reincarnated successfully, this is another matter.

The Three Realms are not an absolute disaster-free paradise, and there is a time limit for them in the chaotic world. However, after the destruction of the Three Realms, it will still be reborn. The Heaven and Earth Breakthrough Supreme Dao Technique of the Pangu Great God's generation is so powerful! However, this can only be done by the descendants who have input divine power into the Three Realms. As long as the divine power is sufficient, no matter how many times the Three Realms are destroyed, they can be reborn and stand in the land of immortality forever.
