# Synopsis of the story of "Echo"
On a snowy night in early 2022, Lu Xun, a graduate student in the Department of Physics, became an experimental assistant in Professor Chen's laboratory to pay for his mother's medicine, responsible for a mysterious quantum device operating at low temperature. He never knew that this machine carried the professor's obsession - his daughter Chen Nian was in danger and fell into a coma on the snowy mountain. The professor tried to use the quantum entanglement of consciousness to transcend life and death to wake her up.
Three years later, Lu Xun has become a top actor, but he is always entangled with unknown fragments of consciousness: osmanthus car incense, cat pendants, the buzzing of instruments... These fragments are closely related to the life of Song Yanyao, a Ph. D. In quantum physics. The two reunited because of their academic connection when they created the science fiction novel "Echo" from the fragments and prepared to adapt it. Song Yanyao is strict and cold, and has no trouble with the top trends. However, during the cooperation, he discovered that Lu Xun's fragments highly overlapped with his own. He even found the device left by Professor Chen in the idle laboratory and decoded the mysterious date "250214".
As the contact deepened, the two finally realized that the experiment back then caused them to generate quantum coupling, and the delay in the transmission of consciousness fragments gradually shortened, and even fragments of the future appeared. The stability of the device continued to deteriorate, not only causing the two to frequently experience memory gaps, but Chen Nian's vital signs also fluctuated. Is this entanglement of consciousness across time and space an opportunity for redemption, or a whirlpool that drags people into the abyss?
When the quantum decoherence crisis comes, they must find the glimmer of light that allows love and obsession to leave an echo in the cracks between saving Chen Nian, protecting each other's memories, and fighting against the correction of the world line - even if the cost is forgetting, those deep marks will eventually regenerate gravity in a strange time and space.
