The ever-moving "Eternity" train is the whole world, the carriage is the class, and the soul is the energy. Here, words have substance: evil words turn into stone, hymns give birth to flowers. The last poet Eurycles, in the wasteland-like last carriage, guarded the embers of the aesthetics of the old era. He discovered the color that only existed in poetry - "Prussian blue", and determined to apply for a patent for this forbidden color and make it his own. However, on the day he unexpectedly won the weird jackpot, the train's core AI "Destiny Loom" gave him an accurate death notice: within seven days, the system would wipe him out. From then on, he embarked on a crazy escape and counterattack: he must use the remaining poems to fight against the malice of the entire world, crack the logic of the mortality prophecy under the law of language as strength and color as power, and establish the dark blue independent kingdom that belongs only to him before the train comes.
