On the day when the mechanical craze of the previous civilization collapsed, human civilization was reduced to mechanical scraps in the ruins. Ten-year-old Lin Ye picked up an endangered guard robot TX-09 among the debris.
He is an orphan boy who was abandoned by the world. He survives by dismantling machinery, and his fingertips are stained with engine oil and dirt. It is a cold metal body with a core command engraved with "Protect Humanity." However, after being repaired by a young man, this protection turned into a paranoia unique to the forest.
On the road to survival in the apocalypse, the wind from the mechanical garbage mountain cannot blow away the warmth of each other, and the poison of radiation fog cannot penetrate the obsession of protecting each other. Lin Ye awakened his mechanical affinity and grew from a timid child to a young man who can take charge of his own business, and the metal heart of TX-09 has already jumped out of the heartbeat of the program as they stayed together day after day.
When the conspiracy of "mechanical immortality" revealed the truth of the apocalypse, and when the cold robot lowered its head for the first time and said in a simulated human voice, "Protecting you, no instructions whatsoever," Lin Ye finally understood that this hard-spoken and soft-hearted robot had already carved him into its core and became his only destination in the apocalypse.
Purpose: The remaining ruins of the last days depend on each other, cross-species protection and two-way redemption
