Shen Yan, an ancient book restorer, had his father swallowed by the power of mountains and seas ten years ago, leaving only half of a fragment filled with strange beasts.
He discovered that the fragments could "write" - whatever he wrote, he lived. Qiongqi broke out of the paper, Bi Fang borrowed the fire to keep warm, and Bai Ze spoke in human language. But every time he writes, a part of him will remain in the book forever.
Until he scratched off his father's name and released the first alien beast, Bai Ze told him: Your father went in voluntarily.
The situation of the gods thousands of years ago, the prison of modern cities, the Book of Mountains and Seas has never been finished - and he is the last word.
