Heng Wuyan, an ancient book restorer, is an introverted young man immersed in the yellowing pages of books, but is troubled by a family mission that has been buried for thousands of years - he is a descendant of the beast guardians of "The Classic of Mountains and Seas", and has the mysterious talent of "heart language" communication with the mythical beasts in the book. After an accidental repair, a broken manuscript of "The Classic of Mountains and Seas" burst into splendor in his hands, awakening the ancient mythical beast Bai Ze from the ink scroll!
However, the vision of the divine beast's resurrection also attracted coveters in the darkness. Gu Mingyuan, a cultural relic dealer, looks elegant on the surface, but is actually very ambitious. He is obsessed with obtaining the power of mythical beasts, and plunders the fragments of "The Classic of Mountains and Seas" at all costs, trying to use the power of mythical beasts to achieve eternal life, and even distorts the nature of mythical beasts to create "evil beasts". Heng Wuyan and Bai Ze were forced into a cultural defense war spanning ancient and modern times. Under the neon lights of the modern city, the roars of ancient mythical beasts are intertwined with the conspiracy laid by Gu Mingyuan. Heng Wuyan must gradually unravel the mystery of his family's mission, find his own value, and protect the forgotten beasts of the mountains and seas while interacting with the mythical beasts, and stop Gu Mingyuan's ambition to subvert the world. He does not have a "golden finger" in the traditional sense, only his obsession with ancient books, his talent for communicating with mythical beasts, and Bai Ze's wisdom. This is an epic collision about inheritance and protection, modernity and ancient times, humanity and divinity. Can Heng Wuyan protect the foundation of Chinese civilization and find the true meaning of a beast guardian amidst the frenzy of revival of mythical beasts?
