A Li is a bionic robot. His main duties are doing the laundry, cooking, and taking care of his owner's every need. But his owner changed his programming so he would call him "Dad."
His dad told A Li that he had another father.
That father had abandoned his husband and child, leaving them alone to struggle through life.
A Li believed him. In a villa worth a billion, he shed bitter tears. So he was a poor child from a single-parent family after all.
Lately, the news has been full of deaths with no apparent cause, and people are panicking. The authorities are taking it seriously, and a stranger has come to A Li's home.
His dad spoke privately with the stranger for a long time.
After the stranger left, his dad told A Li, "We're going to find your other dad."
A Li rubbed his hands together. "Are we going to tear apart the man who abandoned us?"
His dad: ...
His dad: "We're going to put your dad back together. He's been blown to pieces."
