Lin Mo, a young man with the blood of the ancient Hongmeng, was accidentally involved in the catastrophe of the demon king's awakening. Armed with the Hongmeng Sword and the Hongmeng certificate, he formed a partnership with Shen Yan, who was possessed of awe-inspiring energy, Su Qingyue, who controlled water spells, Chu Yao, who could induce sun fire, and Tushan Li, the little princess of the Tushan Demon Clan, to fight against the mysterious forces secretly planned.
From the trembling canyons to the mist-filled Nether Sea, to the ruins of gods that seal ancient secrets, they cracked the maze, fought fiercely against monsters, and gradually uncovered the millennium entanglement between the Hongmeng bloodline and the Lord of Monsters - it turns out that the Hongmeng bloodline is the "key" for the ancient gods to seal the Lord of Monsters, and the "Blood Demon Cult" of the man in black is the mastermind behind the attempt to resurrect the Lord of Monsters and subvert the three realms.
As the secrets of Lin Yuan and other ancestors emerge, the five of them not only have to face the demon king and the remnant soul of the Lord of Demons, but they also have to solve the backlash crisis in their bloodline. From the fierce battle in the canyon to the breaking of the seal on the altar, from the journey in the fog sea to the revelation of the secret of the gods, they used courage as their armor and spiritual power as their blades, and followed the guidance of ancient books to head towards the Blood Demon Sect's main altar, the Meteor God Abyss. The ultimate showdown concerning the life and death of the Three Realms and the fate of blood is about to begin...
