At the glorious moment when the former genius Ye Jingchen reached the pinnacle of martial arts and won the "Crown of Hundred Victories", he was betrayed by his Taoist companion Su Wanqing and stabbed in the heart by him in public, leaving him in the "Demon Burial Abyss".
At the bottom of the Demonic Burial Abyss, Ye Jingchen, who was burdened with a blood feud, did not really die. Instead, he accidentally inspired a mysterious magic order with the word "reverse" in his body, and obtained the "Destiny Grimoire" inherited from the ancient magic way. He used endless hatred as fuel, and after a hundred years of sinking and tempering, he forged a demon fetus in death, reshaped his demon body, and finally became a demon king.
A hundred years later, he returned from the abyss, taking the alias "Ni Chen" and reappearing in the world with burning hatred and undying obsession for revenge. He hid in the chaotic Jueling Ancient Domain, rose up quietly, devoured powerful enemies, and gradually recovered and improved his strength. He vowed to repay the blood debt from the Taoist companion Su Wanqing who betrayed him, the sanctimonious Tianxin Sword Sect, and all the masterminds behind the scenes.
However, as the road of revenge unfolds, Ye Jingchen gradually discovers that there seems to be a larger and ancient conspiracy hidden behind the shocking betrayal a hundred years ago. The "ruthless" sword of the Taoist couple may have a hidden meaning; the so-called leader of the righteous path also hides an ulterior secret. A majestic chess game sweeping the world, involving ancient secrets, taboos about reincarnation and the struggle for destiny, has quietly begun. When the Demon King returns, he not only wants revenge, but also disrupts the established destiny and chess game.
