Among the ruins, the outline of the city emerged like a lingering dream. Qi Shuo, a lampkeeper wandering in the Lost Land, is tasked with lighting the last eternal light. For thousands of years, countless people have tried to wake up the sleeping city, but they have all been swallowed up by despair. However, Qi Shuo heard a faint whisper deep in the stone wall - it was the reverberation of the city's memory and the melody of a tragic song. He wanders between desolation and memory, eager to illuminate those forgotten souls with a glimmer of light, but struggles with his own loneliness and regret at every step. When his former love turned into a shadow and tried to stop him from moving forward, Qi Shuo realized that the price of igniting the light might be to sink himself into darkness forever. The city will not recover, and the tragedy will continue, but his steps have become the only immortal echo in the ruins.
