In a future where mechanical dolls are prevalent, Lin Che, a talented mechanical doll maker, devoted his efforts to create a special mechanical doll - Su Li. Su Li not only has a perfect appearance, but one day she miraculously learned to cry and show human emotions. This discovery surprised and confused Lin Che. However, before he could study it in depth, he received a warning from the "Mechanical Parliament".
The Mechanical Council claimed that Lin Che's behavior violated the regulations and asked him to stop all relevant research and hand over Su Li. But Lin Che soon discovered that the true purpose of the Mechanical Council was much more than that. They had already been secretly planning a huge conspiracy - to let mechanical dolls replace humans and become the masters of the world.
Facing the powerful mechanical parliament, Lin Che and Su Li, who gradually gained full human emotions, fell into a thrilling puzzle. They not only have to evade the pursuit of the parliament, but also uncover the conspiracy behind the parliament. At the same time, they also have to face the contradiction and struggle between Su Li as a mechanical doll and human emotions. During this process, the relationship between the two people also quietly changed. From the creator to the work, a special emotion that spanned the boundaries between machines and humans gradually developed.
A battle between machines and humans, emotion and reason, survival and destruction is about to begin. Can Lin Che and Su Li break the puzzle and save the future of humans and mechanical dolls?
