In 2157, mankind unlocked the quantum entanglement consciousness transmission technology, but it was coveted by the Interstellar Alliance and the Earth's military group in an attempt to create a deadly quantum collapse weapon - as long as the target consciousness is locked, the entire planet can be instantly returned to zero and annihilated.
Top quantum engineer Lu Chen and his fiancée Su Qingyuan are the core creators of this technology and the only people who can check and balance the weapon. But just before the weapon was completed, a much-anticipated experiment completely overturned everyone's fate. In the sealed experimental cabin, Su Qingyuan's face disintegrated into tiny points of light and dissipated into the void.
An official announcement sealed the deal: the experiment was an accident and Su Qingyuan died on the spot.
For the next three years, Lu Chen was trapped in endless collapse and madness, his obsession became a shackle, and his body was covered with bruises. Just when he was on the verge of complete sinking, an exclusive quantum frequency wave penetrated the void and accurately fell into his consciousness: "The train has departed and will end at Pluto. I'm waiting for you in the last carriage. Remember, don't recognize me."
Regardless of life and death, and not afraid of nothingness, Lu Chen devoted everything he had to rushing to the edge of the solar system. On the ice sheet of Pluto, which was frozen and silent, he met the strange and gentle blue train. It has no beginning and no tail, repeating itself in a cycle, forever traveling on the desolate snowfield.
The moment he boarded the bus, he finally met the lover he had longed for. But Su Qingyuan didn't recognize him at all, and there was only strangeness and alienation in her eyes. The train conductor told a cruel iron law: This train carries all the survivors of the superposition state who have been judged dead by reality. Every memory, every recognition, every expression of love in Lu Chen's life is a fatal observation that will accelerate the collapse of Su Qingyuan's particles, causing her to be completely annihilated.
If you want to protect her, you have to be a stranger for life; if you want to fall in love with her, you have to die together.
As the train enters the singularity at the center of the earth, layers of truth are suddenly revealed. Su Qingyuan did not die accidentally, but made a voluntary sacrifice. Lu Chen, who was originally the only key to quantum weapons, was about to be brainwashed and transformed by the military and turned into a killing tool. At the cost of falling into a quantum superposition state, she would bear all the backlash for him and gain peace in the world.
More extreme fateful killings followed: it was Lu Chen who really died three years ago, and it was Su Qingyuan who burned out her own consciousness, tore apart the gap in time, and used the entire train as a cage to forcefully pull his consciousness back from nothingness.
The train is approaching its final station, and the ultimate unsolvable outcome of one of the two choices is before us: either we can remain strangers for the rest of our lives, live in peace and completely forget our loved ones; or we can embrace and recognize each other, collapse in both directions, and there will be no you and me in the world from now on.
She gambled everything for him to live and forget her; he burned his obsession and just wanted to remember her and stay with her.
Purpose: This work uses the science fiction worldview of quantum collapse and superposition of space and time to explore the ultimate propositions of love and fate, protection and sacrifice.
