A "Silk Book of King Yu" unearthed from the tomb of the Warring States Period forcibly bound Xiao Lie, a retired special soldier, and Lin Yuan, a genius with ancient calligraphy whose life experience was a mystery.
In order to find his missing grandfather, Lin Yuan must go to the depths of Kuaiji Mountain in Yuezhou to unravel the real secret behind "Gou Jian's story of lying on fire and tasting gall" - that is not revenge, but a seal.
Legend has it that at the foot of Kuaiji Mountain, the man-eating ferocious beast "Si" and the ancient snake god "Ba Snake" in the "Shan Hai Jing" are suppressed.
When the thermal weapons of modern people encounter the ancient beasts that can move wind and rain, Xiao Lie's triangular army is full of animal blood, and the "Fire Curse" on Lin Yuan's fingertips ignites the sky.
Xiao Lie: "I am responsible for fighting a bloody path, and you are responsible for breaking this damn seal."
Lin Yuan: "No, I am responsible for keeping you alive to see the sun tomorrow."
This is not only an adventure, but also a life-and-death relay spanning two thousand years. When greedy capitalists awaken the demons underground, these two men "abandoned by the world" become mankind's last line of defense.
