Wild Card Creation, As Long As It Works

Chi Yun Su is a transmigrator who has lived for over a decade in F171 Port, a designated garbage disposal site and lawless Black Port on Yuanfeng Star. Operating under the alias Lu Wei, she is the only card maker in her district, crafting defensive and utility cards to survive in the chaotic environment. Her home is fortified with laser traps and hidden mechanisms, reflecting her cautious nature and technical expertise. One day, her security is breached by Guo Ruofan, a highly skilled assassin from the Southern Prefecture who uses invisibility and a silvery-white blade. Despite Chi Yun Su’s elaborate countermeasures, including a poison-laced final attack, Guo Ruofan overpowers her and secures her with a explosive Neck Ring. He demands she help him escape Black Port within half a month, a region she is permanently restricted from leaving due to her criminal record and unique skills.

Chi Yun Su negotiates her compliance by demanding a legal citizen identity, a document she has coveted for years. Guo Ruofan provides a wrist-mounted identity device registered to a male named Rune Mountain, binding her to him through blood. To facilitate their escape, Chi Yun Su assumes the male persona Dashan, using makeup and disguise to pass as an outsider from Long River Industries, a prestigious university. She guides Guo Ruofan to pose as a Garbage Sorter while she applies for a position as a Mechanical Maintenance Assistant at the F171 Port Cleaning Company, also known as Mirror. Their journey through the port is fraught with danger, as local residents attempt to sell them into servitude due to their outsider status. Chi Yun Su orchestrates a diversion, allowing them to reach the Cleaning Company’s trading post, where she bribes an employee with a significant sum of money to fast-track their employment.

Upon entering the Cleaning Company, Chi Yun Su’s true capabilities are tested when she is assigned to an Inspector, a stern engineer named Sun who is frustrated by the incompetence of the existing staff. During a routine check, a machine malfunctions critically, and the Inspector challenges Chi Yun Su to locate a missing screw. Using her knowledge of psychic energy and card circuits, Chi Yun Su diagnoses the issue and repairs the machine in minutes, impressing the Inspector. This act exposes her as a skilled card maker, leading the Inspector to recruit her for urgent repairs in the company’s core zone. The central processing machine is on the verge of explosion, threatening to destroy half of F171 Port. The Inspector reveals that the core cannot be shut down due to the hazardous waste it processes, leaving them with only a short window to repair the failing Blue Card within the machine.

Chi Yun Su proceeds to repair the card directly on the running machine, a technique that defies all conventional card-making safety protocols. She merges her psychic energy with the residual energy of the original card maker, a feat previously thought impossible by the industry. The Inspector watches in disbelief as Chi Yun Su stabilizes the core, buying the company a week of safe operation. Impressed and desperate, the Inspector agrees to teach Chi Yun Su advanced card crafting techniques in exchange for her assistance. Chi Yun Su, recognizing the value of this mentorship, agrees to continue her work under the Inspector’s supervision. However, she remains under the control of the Neck Ring, and her ultimate goal is to master enough skills to escape Black Port entirely while navigating the dangerous political landscape of the Cleaning Company and the watchful eye of her captor.
