Chen Shan in the Daxingan Mountains, from hunter to forest ranger, the turning point in his life is hidden in the footprints left by Grandpa Mu.
That birch bark map led him to break into a forbidden place - the gold mine of the Kwantung Army. The remains of 731's experiments were glowing with cold light. The giant crocodile lizard spit out letters in the cave. The two-headed snake and three-eyed rabbit in the rice bowl in Changbai Mountain concealed the strangeness caused by the magnetic field.
He stepped on bones and saw evil, and finally chose to guard the forest that gave him a way to survive. Wherever the wind passes, there are legends who sacrificed their lives.
