In 2045, astrophysicist Lin Shen captured an abnormal signal from dark matter - a complete historical replay of an extinct alien civilization called the "Echo Tribe". At the same time, he discovered that he had an unexplainable power: quantum echo resonance - he could "hear" the remaining fragments of consciousness from any quantum noise, including the last fears, sorrows and warnings of the Echo clan.
The signals from the Echo clan revealed a terrifying truth: a cosmic phenomenon called the "Quantum Bite" is approaching the solar system, and it will swallow up all complex structures, including life and civilization. The only defense plan is to return the quantum state of the entire solar system to 1962 - but all human memory and history will be completely erased.
