Pangu opened the sky, and the remaining power of chaos divided the three realms of heaven, earth, and humans. Separated by natural barriers, the three realms evolve independently without interfering with each other. The heavenly world relies on spiritual energy to practice, and progress is rapid; the earthly realm is based on yin energy, and cultivation has its own system; the human world is nourished by both spiritual energy and yin energy, and the products are abundant, giving birth to thousands of monks, demons, demons, ghosts, and monsters.
As time passes, three supreme beings are born in the three realms: the Emperor of Heaven, the Emperor of Humans, and the Emperor of Ghosts. The Emperor of Heaven was shackled by the way of heaven and found it difficult to advance in cultivation. He attempted to unify the three realms and seize resources from all realms to strengthen the heaven. Unexpectedly, the human world has a profound foundation, great talents emerge in large numbers from the hidden world, and the conquest in the heavenly world fails miserably. The emperor of heaven dies in depression and is passed down to his son.
The new Emperor held a grudge and formed an alliance with the Ghost Emperor to invade again. The human world is in ruins, and the monks are almost destroyed. At the critical moment, the Human Emperor sacrificed his life and smelted his own body to forge the Human Emperor Sword. The prince turned the tide with his sword and defeated the allied forces of heaven and earth.
The blood of the strong men flowing in the battle was condensed by the power of the Human Emperor Sword to form a solid barrier that separated the three realms. Part of the blood fell into the demonic abyss, was soaked in demonic energy, and condensed into the most precious demon soul stone. The Three Realms have been closed, but the Demonic Soul Stone is hidden under the abyss, and a new crisis has been foreshadowed.
