In Liguo Town, Huxing County, the Huanjian Sect is in danger. The demon Dong Qian threatened to destroy the sect, and the sect master dismissed his disciples, but the orphan girl Bingluo Li insisted on staying and fought with the sect master against the powerful enemy. However, Dong Qian, who came with overwhelming murderous intent, made an incredible request: "Prepare your strongest sword formation - come and kill me."
From then on, the gears of Bing Luoli's destiny began to turn. Carrying the sect's lost secret art "Huan Xin Jue", she broke through in a desperate situation, and by chance, she met Long Yu, the mysterious and well-traveled prince of Prince Jing. The two fought side by side, and a secret love arose. Long Yu worked for her in the royal family and the world, helping the Huanjian Sect resolve the crisis. At the prince's wedding banquet, he proposed to marry her in public and made a promise.
However, their journey as Taoist monks was not an easy one. In order to seek a breakthrough and fulfill their ambition to protect themselves, the two teamed up with their close friends Su Mubai and Tang Yu to embark on a thousands-mile journey of patrolling the border, exploring the sea, entering the desert, and visiting the mountains. They have witnessed the civilized tragedy of the "Void Whisperer" in the ancient city in the northwest, experienced the protective legacy of the "Mountain God's Mansion" in the southwest mountains, and in the hinterland of the Central Plains, they were involved in the shocking conspiracy of the demon sect "Netherworld Sect" to sacrifice children in order to lure the demon god and destabilize the country.
Facing the Netherworld Cult Leader in the god-transformation stage, Su Mubai died without hesitation, igniting the formation with his soul and wiping out all the demons; Bingluoli, in order to prevent the catastrophe of destroying the world, formed the "Core of the Void" and risked being buried in the void with the demon god. Long Yu stirred up the national destiny and fought with all his strength...
They knew each other in adversity and walked together on the road. With the sword in their hands and the feelings in their hearts, they wrote an immortal legend that spanned life and death and protected the common people.
