When Lin Mo, a restorer of ancient texts, buys a damaged copy of the Classic of Mountains and Seas from a mysterious street vendor, he has no idea he has stepped into a world deliberately hidden for a thousand years. The strange beasts described in the book are not myths. They are real, and they are beginning to awaken.
As new words appear on the pages by themselves in the moonlight, a mark identical to that of the nine-tailed white fox from Lin Mo’s dreams appears on his arm. A mysterious woman named Su Yuqing, who calls herself a “guardian,” suddenly arrives with a truth that leaves him breathless: this copy of the Classic of Mountains and Seas is not a record. It is a **seal**. And now the seal is failing.
The full moon is approaching, and ancient beings are about to return to the human world. Lin Mo must work with Su Yuqing to find the three scattered volumes before time runs out. Otherwise, the beasts that were once driven away will tear through the barrier between the two worlds and unleash a catastrophe humanity cannot withstand.
