On the day the sky split, a rift opened in the sky that would never heal. "Inner demons" from other dimensions pour into reality. They have no physical body, but they can parasitize human desires and secrets, turning the entire city into a hotbed of lies.
Chen Mo, a sophomore in high school, accidentally awakened a rare power - mind reading. He can hear anyone's voice, whether true or false, good or evil, beautiful or ugly. At first, he was secretly delighted by this cheat: he had everything under control, including exam answers, girls' crushes, and the teacher's trump cards.
But he soon discovered that the price of mind-reading was far more terrifying than imagined:
Every time he uses it, an inner demon will lay eggs in his brain;
The more lies you hear, the faster the eggs will hatch;
When the inner demon breaks out of his mind, he will become a "hollow man" without self.
What's even more fatal is that in the voice of a murderer, he heard the name of his father who had been missing for three years.
In order to survive and find the truth, Chen Mo must learn to maintain himself in the torrent of countless voices, while at the same time fighting against a mysterious organization that drags the entire city into "collective lies" - the Tianting Society.
And when he heard the whisper of the inner demon that was about to hatch in his body during a fatal mission, he understood:
"You can hear everyone's secrets, but the biggest secret is your own."
