On the branches of the cosmic tree, hang several dimensional fruits that are on the verge of withering, five of which are the most serious, namely: the Secret Realm of Flowers entangled with rotten stamens, the Zerg Kingdom where mechanical carapace devours flesh and blood, the Bird Island in the Clouds torn apart by storms and betrayal, the Forbidden Fish City whispered by deep divers, and the place where everything originates and ends - the Final Universe Flower Field.
The protagonist, Lin Yi, accidentally entered a different dimension and was forced to become a hunter in a secret realm in order to find a way home to the real world. He must: use star cores to rekindle the fire of civilization, and use thorn corpses to pave the way for survival.
In the real dimension, Lin Yi's mother, scientist Su Wan, worked with the Security Bureau to decipher her late husband's research results and discovered that the secret realm her son traveled through was actually a traumatic crack in the "Cosmic Tree"! When the Iron Legion of Thorn Birds tore through the sky of Lop Nur, she grasped the latest research results and weapons, and pointed the gun at the dimensional rift - "My son is fighting for mankind in the secret realm, how can I let the flames of war scorch his return!"
A secret battle between the real world and the secret realm of another dimension is quietly unfolding...
