The killer Long Qi was adopted by his adoptive father Viper since he was a child, and carried out hundreds of assassination missions for him, in exchange for barely enough food and clothing. By chance, he learned that the real culprit of his family's massacre was Viper, whom he regarded as his father. He took revenge in anger, but was severely injured. On the verge of death, Long Qi activates the ancestral dragon ring, obtains peerless magical power, is reborn in Nirvana, and finally kills his enemy. After experiencing betrayal and blood feud, his heart was full of violence, but he met many gentle women during the journey, and they quietly melted his cold murderous heart with their true feelings. He decided to leave his career as a killer. While eradicating the underworld forces and restoring peace to the world, he also compensated the families of the former victims to atone for his past sins. From a cold-blooded killer to a hero, Long Qi embarks on the road of redemption and protection.
