In 2147, human civilization ushered in the quietest end. A cosmic civilization that exists in an information state, the "Silent One," descends quietly without smoke or explosion. In just three minutes, the consciousness of 1.2 Billion people on Earth instantly dissipates. The city is intact and the street lights are always on, but human beings have become the most complete void on the planet. Quantum physicist Lin Shuang became the only survivor and unexpectedly gained the ability to go back in time. With her memories of the doomsday, she returned to the 72 hours before the disaster again and again, trying to warn, prevent, and rewrite the outcome. Once, ten times, a hundred times... Until the thousand and forty-seventh time. In the long cycle, she spent her youth and was burdened with hundreds of billions of separations and despair, and finally understood: The Silent Ones are not invaders, but collectors of civilization. What they want is not surrender, but an answer—— Why are humans remembered by the universe? In order to prove the value of civilization, Lin Shuang gave up changing the ending and embarked on the final journey back to human history: From the walls of the imperial palace where books were burned but still kept, to Galileo's cell where he lowered his head but still looked up at the stars, From the brief ceasefire in the trenches on Christmas Eve, to the bowl of hot rice served by my mother before the end. She finally understood that the greatness of mankind never falls, but that it is still willing to leave a little light for future generations before it is destined to be extinguished. When the time crystal has only its last energy left, When the future of all mankind depends on one choice, Lin Shuang made the loneliest and most eternal decision. She doesn't save the world. She wants to become the last spark of fire for human civilization.
