Ning Chuan infiltrates the Kingdom of Lu to investigate the Shadow Demon Tower, exposing the ruler's conspiracy to collude with the demon clan. He ventures alone into Yin Eclipse Peak and rescues powerful human warriors held captive there. Afterwards, he sweeps through the demon forces, battles across the Western Continent, and continually breaks through cultivation levels, gradually uncovering the shocking conspiracy behind the demon invasion. When the demon clan launches a massive offensive, Ning Chuan merges with the power of the world, turns the tide of defeat for humanity, and leads powerful warriors in a counterattack against the demon realm. He slays the Demon Emperor and ascends to the pinnacle of the myriad worlds. Finally, with a single arrow, he opens the Heavenly Gate, kills the descending True Immortal, protects the myriad worlds, and steps into the Immortal Realm, beginning an even greater legendary journey.
