At 3:17 pm Mars Standard Time, a dust storm is brewing in the Ashedaria Planitia. The orange-red sand gathered into a vague barrier on the distant skyline, like a dormant beast, slowly approaching the "Rusty Harbor" immigration area. The alloy rolling shutter door of the repair shop was ajar, blocking most of the raging sand, but it couldn't stop the dry chill that penetrated the bone marrow. Lin Mo squatted on the ground, holding a miniature laser welding gun between his fingertips. The blue beam jumped on the damaged mechanical parts, making a subtle "sizzling" sound.
