Since Pangu opened the world, although the sky and the earth are 90,000 miles apart, people can still ascend to the sky step by step along the ladder of heaven, and the gods in the sky can also descend from the ladder to the world. The legendary ladder is Jianmu. In this way, there will be no end to the building between man and God. But later, an evil god named Chiyou came to the world and bewitched the Miao people to cause chaos and trouble. In order to protect the good people from harm, the Yellow Emperor launched a huge and long-lasting battle with Chiyou. With the help of the Immortal Nine Heavens Xuannu, the Yellow Emperor defeated Chi You. Zhen Xuan accepted the lesson of Chi You's chaos, and felt that the gods and people did not distinguish between each other, and they could communicate with each other, with more harm and less benefit, so the two of them cut off the passage between heaven and earth, so that people could not go to heaven, so that gods could no longer go down to the earth casually.

Chong and Li obeyed the order, one held up the heavens, and pushed up as much as he could; One holds the ground down and tries to press down. In this way, the heavens and the earth, which were not particularly far apart, have been far away from each other since then. After the Jedi Heavenly Pass, although the gods in the sky can still go down to the earth through great mana, the people on the earth can no longer go to the heavens. The boundless ladder of heaven has become an unbridgeable gulf between the two worlds.

Although the human realm can no longer go to heaven, the powerful mana of the heavenly realm can still come to the human realm, and its huge harm has still not been lifted. So Dayu cast the Kyushu Ding to suppress the luck of Kyushu in the human world and strengthen the seal of the human world, so the powerful immortals who came to the world were suppressed. There is not one power in a hundred, and it is directly suppressed to the range that the leylines can bear, so the leylines stabilize, and there are no more devastating disasters.

Until the time of the ancestral dragon Qin Shi Huang, the ancestral dragon ruled the world. Collect the gold of the whole world, and set up a large array of twelve golden people on the periphery of Kyushu Ding, completely banning the exchanges between the three worlds of heaven, earth and man. And the three worlds of heaven, man and earth are closely connected, and now the separation of the mezzanine human realm in the middle has led to the mixing of the two worlds of heaven and earth into one and turning into the spiritual realm. If the ghosts and spirits of other worlds want to reach the human realm, they must pass through the spirit realm, and then they can only be projected in the void or shuttled by the spirits, and it is absolutely impossible for the body to reach the human realm, even if it is as powerful as a saint.

In this way, the human world will indeed no longer be disturbed by other worlds. However, it also caused the aura of the human world to gradually disappear to the point where it was not enough to use any spells, and gradually became a technological world without cultivating spells.

In this way, the ghosts, gods, and spirits are even more unwilling and unsuitable to come to the human realm, because their powerful spells cannot be cast at all. It's a pity that the good times didn't last long, that is, Jianmu draws strength from the human world to maintain all walks of life, since the spiritual power of the human world is about to disappear completely, how did Jianmu draw strength. After research from all walks of life, it was finally found that Jianmu had mutated, and Jianmu began to absorb the power of the soul. While the human beings in the human world have become weak due to the nourishment of spiritual power, the soul power is outrageously strong.

Originally, the spiritual world continued to emerge to form strange worlds that attracted the attention of those big sects, and after repeated exploration, it was found that these worlds were incomplete and strange, and they could not even be regarded as a world, but there were many small worlds in these worlds, and they were slowly and gradually improving, and everything became extremely strange and weird, but the source of everything could not be found.

Until the existence of the human world was discovered, through Jianmu's research on the human world, he finally discovered that some of the small worlds in the spiritual world were formed by the dreams of ordinary people in the human world; Some are generated by the collective consciousness or beliefs of ordinary people in the human world; Some are forged by the faith and will of ordinary people in the human world...... In a word, the newborn small world of the spiritual world is formed by the soul power of mortals in the human world, that is, the spiritual power. Therefore, the weakest mortal is also the most powerful being.

As a result, all walks of life began to pay attention to this world without spiritual power. Doing everything possible to break through the barriers and gain powerful power, although the suppression of Kyushu Ding and the Twelve Golden People is powerful, it is not without leaks. There will always be some unknown means that succeed in smuggling and cause irreparable damage to the human world. Of course, it indirectly affected other worlds, causing even more serious shocks, after all, the human world is the foundation of the building wood. Therefore, all walks of life tried their best to reach a consensus with King Yu and Zulong in the human world, and set up a spiritual agent to jointly deal with these non-technological supernatural incidents and transgressors, and had the right to directly kill those who caused serious impacts.

This is where spiritual agency comes in. The agents of the spirit world are generally human beings in the human world who enter the spirit world to cultivate through special channels, and then return to the human world to deal with supernatural events in a certain city.
