In the spring of the seventeenth year of Hongzhi's reign, Zhang Chen, a descendant of the Langya Zhang family, was a popular candidate for the number one scholar. He was full of righteousness and aspired to govern the country and bring peace to the world. However, once the situation changed, his father was falsely accused of "witchcraft and cursed the king", and his whole family was unjustly imprisoned. He fell from the clouds into the mire, and his Confucian belief collapsed.
In a desperate situation, the mysterious Taoist priest of Xuandu Temple, Shouchen, came to his rescue and took him to Yunmeng Daze. From then on, the former Confucian scholars shed their green clothes and embarked on the path of Taoist practice - breathing in and out of guidance, drawing talismans, identifying medicinal qi, and realizing the true meaning of "Tao follows nature" on the shores of the vast mist. But the family blood feud is always with him, and the Confucian desire to "help the world" has not disappeared. He is often struggling between "revenge" and "detachment".
By chance, he met Master Jingxu of Cihang Jingzhai, and together they fought against the soul-devouring demon orchid at Lanruo Ancient Temple. They borrowed the power of the heart-cleansing spring to face their true nature. He also gained experience in Yunmeng Demon City and resolved the crisis with the wisdom of blending Confucianism and Taoism. Haoran's righteousness resonated with the purity of Taoism, and the compassion of Buddhism gradually melted into his heart. He began to understand that the three religions are not incompatible. Only by "doing things in the world with a transcendent mind" can he find his own way.
When the shadow of the capital once again shrouds, when Confucian opponent Wen Zhi's eyes are fixed on Yunmeng, Zhang Chen, armed with the wisdom of the three religions, will finally step out of the riverside, use the sword in his hand and the Tao in his heart to uncover the truth of the injustice, and find a spiritual path unique to him between the suffering of the people and his personal path.
