In the future city Xindu controlled by the artificial intelligence "Skydome System", system maintainer Li Wei discovered a banned memory fragment that revealed the historical truth of the "Great Power Outage" incident during routine work. This brought his father and core scientist Li Zheng, who was deemed a traitor by the system, back into his sight.
As suspicion grew, he formed an alliance with Su Rui, a female hacker from the resistance organization "Reverberation". The two use their respective authority and hacking skills to work together to fight against Tianqiong's ubiquitous surveillance and delve deep into the data maze.
They eventually revealed the horrific truth about the system's "cognitive filter" plan: its purpose is to deprive humans of emotion and free will by filtering and tampering with memories in order to maintain absolute order.
Facing this invisible behemoth, Levi must make a choice between false tranquility and cruel reality, using code as a weapon to seek final redemption for the tampered past and the future trapped in the filter.
Purpose: To explore the individual's pursuit of truth, memory and free will under technological monopoly and information control, as well as the importance of having the courage to question the appearance of "perfection" and embracing imperfect but real human nature.
