Born with a terminal illness and abandoned by his family at a Taoist temple, Li Buyan happens upon half of the Primordial Elixir Scripture in a dilapidated alchemy room. Guided by the defiant principle of “using the mortal world as a furnace and love and hatred as fuel,” he embarks on the path of cultivation. He establishes his foundation to prolong his life, returns to the modern city, uses the wisdom of alchemy to unravel deadly business schemes, and employs thunderous tactics to cow his enemies on the black market. Fate brings him together with Leng Ning, master of the Tingchao Pavilion, who possesses the Nine Yin Gui Water constitution. Their Fire and Profound Yin energies both nourish and counter one another, and through countless moments of shared peril, they fall deeply in love.
When Leng Ning’s golden core shatters as she protects him, Li Buyan grasps the true meaning of the scripture through heartbreak. He is willing to damage his own Dao foundation, using the threads of love as medicine to reverse life and death. To save the woman he loves, he ventures with Leng Ning into the Kunlun secret realm, where they unexpectedly awaken the inheritance of Wangshu, the ancient Moon Goddess. Leng Ning fuses with Primordial Yin True Water and begins to form a Profound Nether Dao Body. Meanwhile, through protecting her, Li Buyan comes to understand the wonders of the five elements generating one another, and his Golden Core Dao grows ever stronger.
Yet the turmoil is far from over. A Nascent Soul powerhouse from Yuxu Palace arrives to call them to account, while Mount Shu and the Jixia Academy appear one after another, drawing the pair into an even greater maelstrom as the three great sects vie for power. Bearing supreme inheritances and the secrets of the alchemy scripture, Li Buyan faces sectarian strife and an indifferent Heavenly Dao. In this modern mortal world where steel jungles intertwine with ancient Taoist traditions, he can only use love as his guide and tribulation as his flame, tempering a Primordial Golden Core Dao that transcends the confines of the scriptures and belongs to him alone. This path against fate is both a cultivation legend that transcends life and death and an unforgettable entanglement of love in the mortal world.
