The Emperor of Desolate Heaven, Shi Hao, has arbitrarily ruled for eternity. He cut off the years with one sword, suppressed the source of the Dark Immortal Emperor, and stood alone in time and space for eternity. Everyone knows that Emperor Huang Tian is invincible in all the heavens, and no one can surpass him in all eternity. But - Huang did not really end the darkness. He only sealed it, not eradicated it. Darkness is not a foreign enemy or a foreign race, but the inherent flaw of the Great Way of the Universe. The Immortal Emperor has a way, but there is no way to return to the ruins. After an eternity, the seal was loosened, and the desolate energy scattered across the sky, and the only original desolate bone lost by the Desolate Heaven Emperor was born in the world. The protagonist is the reincarnation of this desolate bone, which carries the unfinished fruit of the desolate path, the eternal regrets, and the ultimate darkness that has not yet been cut off.
