I'm Really Not the Reincarnation of the Sword God

Three hundred years ago, a great melee broke out in the Lonely Dynasty. Under the leadership of the second-generation Demon Sect leader, the demon clan swept across sects all over the world, staining the nine continents with blood. The human race was completely defeated and lost its power. Since then, the demon clan has taken control of the cauldron, and the human clan has had to stand in every corner of the dynasty, struggling to endure hardships and practice cultivation. The world is suffering, and demons and monsters are rampant in the world. Due to the powerful strength of the four demon clans, the three major immortal sects have no choice but to protect themselves and abandon all living beings. Three hundred years later, Li Shisan, who lives in the world of martial arts, travels back to this world. He originally just wanted to earn money to buy a house and live in peace until old age, but by various chances and coincidences, he got involved in the road of revival of the human race, and step by step he cultivated to become the peerless sword god. Finally, he led the sword sect to drive the evil spirits headed by the demons into a place of eternal destruction, and restored peace to the world. From then on, what he said became myths.
