In the broken place called "The Realm of Vientiane", the sky is the remains of the solidified machine god, and the earth is filled with rusty rivers. This place is not a creation of nature, but a shelter forcibly "woven" by the last glorious civilization - the Mecha clan - with its own bones and final strength before its demise. However, the world itself is collapsing, and "world rust" is like a wound that cannot be healed, eroding everything. The remaining creatures struggled to survive, using the "source matter" energy escaping from the remains of civilization, and embarked on three completely different paths of transcendence: the mechanical master who used machinery to create external forces, the chakra warrior who used the source matter to reconstruct his body, and the law officer who programmed laws with laws and regulations - this is the path of Jishu.
