In the first year of the Eclipse Era, the clouds at the zenith condensed into an upside-down gray sea, swallowing the earth from west to east. After the boundary called the "grey line", there is eternal night, whispered ghost stories, and the Zhaohai towers that are still stubbornly discharging; before the gray line, the days are getting shorter day by day. The last "blood vessel" of the world is the warp railway that runs through the ruins.
Cheng Ye, a young locomotive technician, repaired the sealed maintenance train in the section bit by bit into a living thing and named it "Zhuri". He made a decision that many people didn't dare to make: head east - rush into the dying light of the sky before the gray line turned Yuzhou into ashes.
People in the car came one after another: Lu Wangui, a female dispatcher with an excellent memory; Chi Dai, a discharge girl who can burn out a car's electrical appliances while sleeping; and further away, Mu Ying, a tower guard girl who had seven years of her life stolen by the tower.
People in this sea of gray will forget who they are little by little. So every morning and evening, they checked their watches and reported their names - your name is Cheng Ye, my name is Lu Wangui, and we are going east.
The gray sea can swallow the sun, but it cannot swallow the memory.
The Sun Chaser headed east. The car will not be destroyed, but the people will not be forgotten.
