A Healing Guide for Beautiful, Strong, and Tragic Revenge Seekers [Quick Transmigration]

A couple who are both taskers, told from the male lead's perspective. Also known as: "The Fluffy Little Creature I Want to Adopt Is Actually My Powerful Coworker?!" A feel-good power fantasy. The mission theme in each little world is revenge for the beautiful, strong, and tragic. -- I met her when my life had hit rock bottom. She was the perfect all-around housekeeper. She prepared delicious meals for me, pressed my suit for dinner parties, and kept my house as immaculate as a palace. She made me so happy that I almost forgot: she was a tasker I'd summoned by offering up my soul. She punished the scum who hurt me. She won justice for me after I was wrongfully accused. She drew up a meticulous revenge plan for me, making me lose myself in the thrill of getting my revenge. But there was never any warmth in the way she looked at me, only the polite composure of an outsider. With everything ready, she stood in the shadows and handed me the blade of vengeance. Through her pristine white satin gloves, she clasped my trembling hand in hers. Then she guided it with precision to strike my enemy's vital point. "The contract is over, and the mission is complete. I wish you a peaceful life from here on." She pulled out the blade. As she lowered her head to wipe away the blood, she also erased every memory of her from my mind. I stared blankly at the elegant woman before me, a stranger. She smiled and walked past me, then vanished like a dream from which I had just awoken. 'Her' name was Wen Hui. She worked for the Other Shore Agency and was a top performer in the Revenge Division of the Grievance Removal Department. For Wen Hui, the revenge that her clients had exhausted themselves trying to achieve was just another minor entry in her work record. She never grew attached to any of her clients. Their souls and their next lives would become her payment for completing their missions. -- Even a tasker who seems perfect in every way has old wounds she cannot speak of. A doctor cannot heal herself. Though Wen Hui had dispelled the grievances of many clients, she could never find a way to come to terms with her own past. She traveled through different times and spaces, studying the seemingly impossible question of how to eliminate resentment completely. Driven by a selfish impulse, Wen Hui added her own hidden past to the pool of client missions. A disastrous start from the start, combined with a body that attracted bad luck, made the mission a legendary challenge with a completion record of zero. But then someone suddenly broke that record. ...Just how had they untied the knot in her heart? Wen Hui found herself curious. In a simulated scene, she watched another tasker rewrite the fate of her past self, who had been enslaved. Wen Hui thought she was finally being healed. But that person actually said: "Do you know what kind of creature the client in the test is? Its fur is so soft. I want to take one home and raise it, so I can pet it every day!" ...? -- World One: A Ruined Stardom (Complete) The starlet Cui Qizhen was struck by a curse. Several times, she made a fool of herself on camera, and the career she had painstakingly built over many years was destroyed in an instant. A famous actress attracts envy, and plenty of people hated her, making it hard to figure out who was really behind it. Tormented by nightmares, she chose to offer up her soul in exchange for a chance to find the person who had cast the spell and take revenge. World Two: The Fate-Swapping Spell Anna was the true heiress, inheriting her family's gift for magic. She thought returning to her family would guarantee her a worry-free life, but the false heiress framed her until everyone turned against her. In despair, she chose to make a deal with the Other Shore. The previous tasker had avenged her by punishing those people, but her life did not seem to get any better... World Three: A Cage from a Past Life Some strange beasts are born ill-fated. All of its kind died at the hands of cultivators who hunted them down. After wandering alone to a village of mortals, it went through countless hardships before the villagers finally accepted and took it in. But not long afterward, a natural disaster destroyed the village. Then came its story of being captured by the Spirit Beast Sect, tamed, and enslaved, until its beastly bloodline finally ran wild. If it was born destined to die in a cage, was it truly undeserving of any other way out? [Important! The core of every story is punishing evil and rewarding good. Anyone who does something wrong will be punished, including the clients.] [Important! Revenge is only the client's obsession. The mission stories begin with hatred, but all end on a healing note!] [Important again! Revenge is not the goal, but the means. The heroine only takes on missions to dispel her clients' resentment. The story ultimately encourages everyone to let go of hatred and obsession, and bravely embrace a new life!] [Notes before reading] * The heroine's true form is a monster. * A slight harem-like appeal (because the author deliberately wanted to write something indulgent). * Taking on missions is work. Finding meaning in life while living forever is life. * The setting includes multiple ethnicities and cultures to enrich the worldbuilding, with no intention of causing offense. The mission worlds are fictional, so please don't scrutinize them for historical accuracy. * Revenge missions are the main focus, along with cooperative missions and missions to eliminate wild Systems and correct the laws of the worlds. * The heroine was inspired by Sebastian from Black Butler. The plot is unrelated and is not a derivative work, and the story does not encourage the act of 'selling one's soul.' -- A sweet-romance trainee with two and a half days of practice. I'm still frantically trying out different titles (I'm really a mess). The next mission world will be chosen from three options in the comments. Feel free to follow along and join the discussion. Theme: Learn to let go of obsessions and embrace the better things life has to offer.
