The ancient book restorer Lin Yan, when he touched the fragments of "The Classic of Mountains and Seas", traveled through time and became a young man in a tribe in the wilderness. The beginning is a pile of corpses at the bottom of Batu Cave, with broken sternum and ferocious beasts around. When he is about to die, the talisman of the chest bone explodes and reshapes his body. He also hears the instructions of the ancient remnant soul: Find your parents.
He crawled back to the tribe, and his sister Lin Xi cried and hugged him, but he clearly remembered that when he was reborn, she watched coldly at the entrance of the cave, waiting for him to die. Lin Yan kept silent, while playing the role of the weak younger brother, he used bone talismans to unlock magical powers of mountains and seas. By repairing ancient books, he could tame ferocious beasts and decipher the secrets of the great wilderness.
Following the clues left by his parents, he traveled through strange mountains and rivers step by step, only to discover that his sister's abnormality and the secret of the bone talisman all pointed to the eternal chess game involving Zhulong's remnant soul. All forces in the wilderness are looking for him, some want to seize the bone talisman, and some want to use his bloodline to open a secret place. Lin Yan solved the crisis while uncovering the truth, and finally realized that his sister's indifference was the deepest protection, and his destiny was to reverse the destiny of the mountains and seas that had been manipulated by others.
