Lin Yuan, a modern college student, lost his job after graduation, his girlfriend cheated on him, and his parents urged him to get married. While drinking alone on a rainy night, he was struck by a bolt of blue lightning falling from the sky. After waking up, I found that I had traveled to the ancient world described in the Classic of Mountains and Seas - a different world shrouded in the "Great Wilderness".
In this world, all the strange beasts recorded in the Book of Mountains and Seas really exist, but they are not as peaceful as the legends say. Instead, they have been eroded by "barren air" and turned into ferocious mutated creatures. Human beings struggle to survive on this continent and rely on practicing "spiritual patterns" to fight against alien beasts.
Lin Yuan found that he had awakened a special ability - the "Illustrated Book of All Spirits", which allowed him to see the detailed information of all creatures (attributes/weaknesses/evolutionary routes/taming conditions), and had the ability of "spiritual engraving" to tame and strengthen alien beasts.
