Shen Yan, an abandoned son of a wealthy family, was regarded as a "medicine man" by his family since he was a child, and his blood was constantly drawn to keep his brother Shen Zheng alive. After he was squeezed out of his "death", the family actually held a ghost wedding for him. However, at the funeral, Shen Yan woke up from the blood coffin. His extreme resentment triggered changes in his body, and he transformed into a vengeful Shura.
He escaped from the Shen family, awakened the ability to control blood in a desperate situation, and gradually established his own organization "Xu". From exposing the ugliness of the Shen family's "Medicine Man Plan" to publicly destroying the prestige of Shen Zheng and his family, Shen Yan's revenge moves step by step. However, he soon discovered that the Shen family was just a "pasture" raised by the ancient and evil organization "Blood Eaters", and that he was the "key" to his cultivation.
As the mystery of his life experience is revealed, Shen Yan's true identity is actually a descendant of the ancient divine blood civilization - the successor of the "Emperor Blood". His battle has escalated from family feud to a battle for the survival of the race against the "Blood Eaters" and the "Eternal Blood Feast" behind them. Shen Yan continuously awakens his power, integrates global forces, and ultimately protects the world, defeating the ultimate enemy after paying a heavy price.
After the victory, Shen Yan, armed with the power of the abyss, has become a being beyond common sense. He chose to wander alone among thousands of worlds and transformed into an "Abyss Walker" who protected the balance. His name and beliefs became the immortal legend and beacon of the new civilization...
