In order to prolong the life of his daughter Yaya, who suffers from a congenital cold condition, mountain villager Zhao Daqiang risks his life to break into the bottom of the valley to pick blood ginseng. He accidentally runs into the white Qilin mountain god Bai Shanjun, who has been chained with a mountain-suppressing cold iron chain by his biological older brother Heiyao for a hundred years. A promise, a mortal enters the game. Relying on the thermal expansion and contraction earth method passed down by an old stonemason, he withstands heavy rain, charges into an ice pool, and blocks the fire with his physical body to protect the fire pit, abruptly smashing the immortal cold iron that even immortals cannot break free from; to guard his daughter's life candle, he holds a knife to block the door and stubbornly resists the nether ghosts demanding his life, defying life and death with the obsession of fatherly love. This ripple stirred up by a mortal eventually breaks through the mountain god brothers' century-old biased grievances, and also turns an ordinary commoner into the most respected person in Wanshou Mountain.
