Mo Chen, a down-and-out scholar in a small town in the mortal world, came from a poor family since he was a child. He studied hard just to live a stable life. He was born ordinary and had no chance of immortality. People around him believed that it would be difficult for him to embark on the path of spiritual practice. By chance, he unexpectedly awakened the ancient sacred bloodline that had been silent for thousands of years in his body, and since then he has possessed a golden finger that defies heaven. This human world has long been secretly infiltrated by the demon world. The domineering demon king is in charge of the demon world, overlooking the three realms, treating mortals as ants, killing and plundering the destiny of living beings wantonly. With the common people in mind, Mo Chen relied on his firm will and extraordinary courage to embark on the path of immortality with a mortal body. He used the power of his blood to overcome desperate situations and rose up from a mountain scholar step by step. He killed demon disciples, broke into secret realms, formed comrades, and fought powerful enemies. He made a comeback along the way, broke the rule of the demon world, and used his humble bones to compete with the supreme demon. He started a legend of a passionate fairy tale in which mortals fight against gods and demons and shake the order of the three realms.
