Humanity has full access to the "LingNet" - a global consciousness sharing network composed of quantum neural cloud, brain-computer interface and emotional AI. The original intention is to eliminate barriers and achieve empathy. But when 98% of the population experiences extreme emotions (such as war panic, ecological despair) at the same time, the spiritual network produces an "empathy avalanche" and triggers a protective protocol: forcibly cutting off all neural connections and locking human consciousness into a deep state of silence (brain waves stagnate, physical body survives).
Consequences: 99.3% Of the world's population has become "Silents": eyes open but unconscious, able to breathe and metabolize, but unable to think.
The technological society collapsed instantly, and the city was swallowed up by plants and crystallized buildings.
The remaining data of the spiritual network dissipates into "Mnemo-dust" and floats in the atmosphere.
Cultural translation: Later generations called the "Spirit Net" the "Tian Luo Vein" and the "Great Nirvana" as the "Retreat of the Human Heart"
