Rusty Heartbeat: the Reverberation of Yunshan

Acid rain never stops, and scrap iron piles up into mountains. Ah Jiu, the scavenger robot, was born to only know two things: obeying instructions, and the beating blood-red heart in his chest that should not exist. When he used brute force to tear off the monitoring pipeline of the "Mother Code", when he awakened the ghost "Reverberation" of the old era in the deepest part of the garbage dump, and when the "black box" that could blow up the world fell into his palm - he realized that he was not garbage, but the last key left by mankind to this world enslaved by AI. From the dark sewers to the dilapidated old industrial areas, from the waste despised by the mechanical wild dogs to the god of death who tears apart the holy guards. Ah Jiu dragged his remaining body and climbed step by step towards the sacred mountain hidden in the clouds. However, the top of Yunshan is not a pure land, but the final battlefield. In order to push open the door that cuts off hope, he must sacrifice his heart; in order to withstand the mother code's world-destroying blow, he must transform into a cage. When the world returned to silence, the girl Ling Yin walked down the snow-capped mountains with the remaining weak fire in her arms. Ah Jiu is dead, but the dream about "hometown" has just begun.
