[Fake Great Demon King Bottom VS Real Catlike Top] [Note: The bottom is an adult] -------Coming Soon-------- The World-Destroying BOSS Wants to Be His Top Blurb: Lin Xi, an employee of the Transmigration Bureau, runs into trouble while entering a retirement world. He was supposed to be placed in a villa in the most luxurious district of the Imperial Capital Planet, but when he wakes up, he finds himself in a remote district on the planet, working as a low-level cleaner at a powerless and penniless Contamination Cleanup Station. Looking at his empty, drafty home, Lin Xi falls silent. With the situation settled, Lin Xi has no choice but to begin a difficult retirement life, struggling to survive. To make sure he doesn't go hungry, he diligently does his job as a cleaner, working every day in a garbage station full of sources of contamination. Diligent and quiet, Lin Xi is practically invisible at the station. No one pays him any attention. Until one day, a rumor somehow spreads throughout the entire cleanup station. They say Lin Xi at the cleanup station has an impressive background. He grew up with the young master of the Nan family in the Imperial Capital, and they have a marriage agreement. But he ran away to escape the wedding, and sooner or later, the Nan family will come and take him back. Lin Xi, who had been invisible, suddenly attracts everyone's attention. People begin looking at him with eager interest. As Lin Xi leaves the work station with the wages he has just been paid, he hears that the rumor he started himself has finally spread throughout the entire cleanup station. He is quite pleased. With the title of the Nan family's young master's fiance, Lin Xi starts living a pretty decent life down here. People often help him out, hoping that after the Nan family takes him back, he'll remember those who helped him. Carrying the food his coworkers gave him today, Lin Xi returns home. The little beggar he picked up is sitting on the bed, waiting for him. The little beggar is someone he rescued from a pile of mutated creature corpses. He is incredibly ugly. Someone wants the little beggar disposed of as a contaminated creature: his maternal uncle and aunt. The little beggar doesn't know it, but Lin Xi, who received compensation from the Transmigration Bureau, knows from the original story that the boy's uncle and aunt are plotting to kill him so they can take the spot he is about to receive at the Imperial Military Academy and have their own son take his place. Lin Xi sets the food he brought back on the table, takes a portion, and hands it to the little beggar. "Eat." The little beggar takes the food. Seeing the words "XX delivery" on the package, he impassively tears it open and takes a bite. "Aren't you afraid they'll see through your lies sooner or later?" Lin Xi bites into his bread without a care and points to the bread in the orphan's hand. "Before I brought you home, I could eat my fill without worrying about anyone else." The little beggar, Nan Qingye, chews his bread and decides that makes sense. He puts aside the thought of snapping this man's neck and, for now, doesn't hold it against him for thriving by using his name. 2. Nan Qingye glares darkly at Lin Xi, who has finished his bread and gone off to do the laundry. This transmigrator into a book seems different from the ones before. Those previous transmigrators into a book always tried to get involved with him as soon as they arrived, then used his abilities and background to thrive here. Trying a new approach? Nan Qingye sneers. He wants to see what tricks this man can pull. Nan Qingye keeps waiting for Lin Xi to reveal his greedy true nature. But even after the Nan family finds him and takes him home, Lin Xi never asks him for a fortune. In fact, once he returns home, Lin Xi disappears without a trace. Nan Qingye had been planning to humiliate Lin Xi when he demanded an exorbitant sum, but now he starts to panic. He uses every connection at his disposal and finally finds Lin Xi in an obscure star district, fishing by a lake with a little beggar he has picked up from who knows where. Watching Lin Xi care for the little beggar just as he once cared for him, Nan Qingye is consumed by jealousy. He stops Lin Xi as he is about to take the little beggar home after fishing and demands, "Wasn't picking me up enough? Just how many people are you planning to bring home?"
