Others rely on talent, adventure, and golden elixirs to achieve immortality, while he relies on an ancient geographical annals to achieve immortality - when you open it, you will find an illustrated book of strange beasts, and when you read it, you will find ancient techniques. When you collect the fragments, you can suppress the four evils of the prehistoric times. Wasted spirit body? No, he just opened the book a little late.
"The Classic of Mountains and Seas" has never been a travelogue. It is a seal.
The four ancient evils - Taotie, Qiongqi, Taotao, and Chaos - were suppressed at the four poles of heaven and earth, locked by the scriptures of mountains and seas, and chained by the spiritual veins of mountains and rivers. And the chains are breaking inch by inch.
In the end, when the four evil spirits break the seal, the heaven and earth are overturned, and all living beings are in ruins, he will hold up the finally complete Book of Mountains and Seas and ask the world -
"I'll seal what you can't seal."
