Fogbound Train: My Synthesis Station Can Evolve Without Limit

Lin Wu, a former quality inspector at a machinery plant, hits rock bottom after being framed in a wrongful case. When she opens her eyes again, she is aboard the Eternal Night Train: a battered carriage, fog outside the windows that devours reason, and a ten-minute countdown on her novice protection period. The scrap metal others see is lifesaving material to her. After activating the "Universal Synthesis Bench," she dismantles the carriage with an engineer's precision, synthesizes a reinforced steel door lock, and, just as a monster breaks through the door, bears the cost of mental contamination to buy two companions a chance to survive.

The train never stops, and neither does the fight to survive. Zhou Mingyuan, a man in a suit, hides a medical report about his daughter's illness. Chen Xiaomeng, a girl with dyed blond hair, can hear the frequencies of monsters' emotions. The three are forced to team up and struggle to survive in a Class D fog zone. From mines to mechanical ruins, from a silent library to a church of flesh, Lin Wu breaks the laws of synthesis through free recombination and refines the essence of monsters in a flesh-and-blood furnace. But each time, mental backlash pushes her closer to the brink of collapse.

As the truth about the "Eternal Night Project" gradually comes to light, Lin Wu discovers that this train is no natural disaster but a conspiracy using humans as test subjects. The conductor was once a hero who saved the world, but the abyss corrupted him into a tyrant. The monsters wandering the train were all once living people. When the marks on a brass pocket watch align with the truth of her past, and the curse of the "Godslayer" descends, Lin Wu must find a third path beyond "becoming the new seal" and "destroying everything": she must become a bridge and forge the dawn anew.

This is an abyssal journey about sacrifice and redemption.
