He who listens to the abyss will eventually be whispered by the abyss. Ling Haiyao, a rising star in marine archaeology, led a team to explore the Mariana Trench and accidentally discovered a glazed temple that had been silent for thousands of years. The texture on the wall is neither carved nor carved, but actually a living neural map. When your fingers touch the cold palace wall, the familiar mother tongue twists into an indescribable alien whisper in your ears - cognitive pollution erodes your sanity like a tide. In order to combat the "whispering plague" from the deep sea, Ling Haiyao teamed up with the cold-faced neurolinguist Pei Yanzhou to build a fragile "symbolic firewall" with laughter and the aroma of hot pot in a claustrophobic steel submersible. When the resonance of the temple plays a prelude of destruction in the minds of the team members, they must risk everything and dive into the eye of the boiling hot spring to find the only antidote to madness. This is a cognitive battle that breaks out in absolute silence and is about the last line of defense of the human mind.
