In the supernatural city "Tianshu City" in 2099, the hierarchy of beast masters is strict, with family crests as class markers. The beast master needs to sign a soul contract with the original beast and achieve evolution through fighting and resource feeding. However, healing beasts are regarded as useless because they cannot fight directly, and their users are mostly reduced to auxiliary tools. Children from poor families can only live in the "Rust Zone" and obtain meager resources through black market transactions, while wealthy families control the core evolutionary secret realm and rare spiritual plants.
