Demon Venerable, Immortal Emperor

Tell me, in this world, between a righteous heart and an evil heart, which is the true heart? Between the Immortal Emperor and the Demon Venerable, who is the true ruler? The universe is boundless, and space and time overlap without end. In this universe, said to contain three thousand great worlds, countless beings toil in their pursuit of immortality. With myriad races standing side by side, the most extraordinary talents can shake the universe with a roar and tread across three thousand great worlds with a single step. Among them is the Nine Profound Great World, where the righteous path and the demonic path are sharply divided. Righteous arts and demonic killing arts unleash endless bloodshed and resentment. Here, the young Long Jiaoyang of the righteous path happens upon the chance to cultivate demonic arts, becoming the one and only person in the world to cultivate both paths. What will he ultimately become? A Demon Venerable, an Immortal Emperor, or a crippled man, undone by the clash of righteous and demonic spiritual power?
