The dusk of the Mechanical City is always shrouded in rust-colored mist, and the life of Lin Jin, a low-level mechanic, repeats like a precision gear—until that night of energy storm.
When he was twelve years old, he witnessed his mother being swallowed up by energy turbulence during a riot. The meteorite pocket watch he was holding tightly in his arms suddenly burst out with a faint blue light. The nebula pattern on the inside of the watch cover perfectly coincided with the star trails in the sky. The last words his mother gave him before she died, "Remember, time is round," became the sharpest thorn in his side in the past thirteen years.
Nowadays, Lin Jin is the most outstanding maintenance apprentice in the Machinery City, but during a routine maintenance, another mutation was triggered: the pocket watch vibrated like a heartbeat, the prosthetic eye scanned the "Scavenger" team being chased by the city defense army, and the girl in dark green uniform Su Li who rescued him had mechanical patterns behind her ears that flashed at the same frequency as the pocket watch.
When the two hid in the ventilation duct to escape, an even more horrifying truth emerged - Su Li's chip actually resonated with the pocket watch, projecting a holographic image of twelve-year-old Lin Jin hugging the pocket watch in the storm; and the whale's cry from the depths of the crack overlapped with his mother's last call in his memory.
It turns out that he is the last bloodline of the Starfall clan, and the pocket watch is the key to opening the rift in the star orbit. This pursuit, which lasted for thirteen years, originated from the three city-state alliance's greedy plunder of star nuclear energy. Is Su Li's approach to him a conspiracy of the Star Thieves or an unspoken bond with his mother?
When Lin Jin stepped into the star orbit crack with his pocket watch in hand, a different-dimensional space intertwined with machinery and magic unfolded before his eyes: the floating star core beat like a heart, the figure of his mother gradually became clear in the memory fragments, and Su Li's mechanical lines began to spread.
