At the beginning of the story, the protagonist Zhao Tian uses his identity as a businessman as a cover and takes a barge to arrive at the giant passage "Sky Chain" connecting the "Floating Island" Helland and the "Rust Belt Market". He relied on the "Resonance Stone" obtained from the abandoned mine and his shrewd disguise, taking advantage of the guard's greed and reverie about the legend of the "Chain Heart Fragment" to skillfully pass the dock inspection, demonstrating his **witness and disguise ability** in the context of the exile.
