Young Zhao Yu was cruelly betrayed by his girlfriend after his spiritual bones were taken away by his sect, and his sect ruthlessly abandoned him. I thought this life would end like this... Unfortunately, he was not destined to die. He was possessed by the remnant soul of a demonic giant from ancient times. He regained his life and obtained the ancient magic power - the Blood Sea Demonic Art. This Blood Sea Demonic Art is so abnormal that it can become stronger as long as it absorbs blood. So Zhao Yu embarked on a path of blood-sucking. From then on, the number one "devil" in the world of immortality was born. Although Zhao Yu is a demon, he acts openly and aboveboard... On the contrary, some so-called righteous people do all kinds of bad things... Decisive to kill + Not the Holy Mother + Revenge + Upgrade flow + Slow heat + Single female protagonist
