The System's sweet voice rang out, making Tang Lingnan clench her fists even tighter. Her face twisted with fury. She took a few deep breaths before forcing out a few words through gritted teeth. "I remember the contract said in black and white that the first world would be a beginner level, simple and easy to get through. Is this what you call simple?" If the System had a physical body, Tang Lingnan would have stuffed it in a sack and beaten it a hundred or a thousand times. All she could do now was humiliate herself by cursing its ancestors for eighteen generations. She only regretted that she had been young and foolish before she died, and fallen into the System's trap. "Dear, there's only two minutes left on this call. We recommend that you not get too hung up on this little issue." Tang Lingnan's fury only grew, but she had to swallow it for the sake of the mission. How dare you! This is outrageous! Tang Lingnan had died at just twenty years old. To come back to life, she had no choice but to sign an unfair contract with the "Redeem the Dragon-Proud-Heavenly Protagonist Brother" System and work for it without pay in world after world. "So what exactly does a wish-fulfillment story's Dragon-Proud-Heavenly male lead need redeeming for? He has success, fame, and beautiful women by his side. What could he possibly be unhappy about?" Tang Lingnan, an ordinary commoner, despised that kind of showy behavior and wished she could trade places with him. World One: Urban Superpower Dragon-Proud-Heavenly Protagonist. (Complete) (If you don't like it, you can skip it.) They promised a domineering CEO who built an empire from nothing. How did it turn into an urban superpower battle story? World Two: Discarded Young Master of a Wealthy Family, Dragon-Proud-Heavenly Protagonist. (Complete) A discarded young master from a wealthy family, and you give me spiritual qi revival? World Three: Western Fantasy Transmigrator, Dragon-Proud-Heavenly Protagonist. (Complete) Why can the Dragon-Proud-Heavenly Protagonist travel between two worlds whenever he wants, but I can't? World Four: Future Interstellar Dragon-Proud-Heavenly Protagonist. (Complete) Angels, elves, and vampires, a grand alliance of magic and mechs. What more do you want from me? World Five: Primeval Wilds Dragon-Proud-Heavenly Protagonist. (Complete) A double-pupiled supreme being with a Chaotic Constitution, and then a transmigrator steals his fate and his life. How am I supposed to survive? World Six: The Amnesiac Returns to a Love Rival Showdown. He wakes up one day, and somehow the world feels different. Tang Lingnan scratches her head, completely baffled. In short: A lighthearted, silly plot, focused on siblings redeeming each other, with the female lead somewhat doted on by everyone. [Take a look, dear readers, and see if there's a world you like, qwq.] Theme: Family is the most beautiful sight at the beginning of life. This is a story of a brother and sister supporting each other and growing together.
