Beneath the modern metropolis of 2026 lies an ancient truth unknown to the world. This is an age of declining magic, when spiritual energy is scarce and the legacy of cultivation is fading. The few remaining "recluses" are scattered among the common folk, abiding by the "rules of the mundane" that forbid them from revealing their powers. Yet ancient evils sleeping deep within the city's ley lines are gradually awakening as the spiritual energy of heaven and earth stirs faintly once more. They lurk in the shadows of neon lights, devouring humanity's fortune. At the same time, many ancient seals are beginning to weaken, and the balance maintained for thousands of years is on the verge of collapse. Beneath this seemingly ordinary jungle of steel, a silent vigil to protect the fate of the world has begun!
