Don't Mess with the Little Heiress! The Apocalypse Big Shot Is a Sis-Con

【Apocalypse + interdimensional merchant + everyone's darling + reborn + leveling up + overprotective brothers + power couple + feel-good + big shots + ensemble cast】 Global disasters strike, order collapses, and a brutal apocalypse descends! In the third year of the apocalypse, the Si family's real daughter pushes their fake daughter, Si Qingning, into a horde of zombies. The three foster brothers she trusted watch coldly as she dies, unable to rest in peace. Reborn, she vows to take revenge on everyone who wronged her. She will never hand over the jade pendant that proves her identity again. The pendant recognizes its owner, comes with its own space, and activates an interdimensional trade System. From then on, she sets out on the path to becoming stronger. By chance, she meets her biological brother Lu Jin, who has spent years searching for her, as well as Pei Zeli, her childhood betrothed. Both Lu Jin and Pei Zeli are powerful figures in the apocalypse. Together, they go on to build the strongest secure base of the new era. Lu Jin is a fearsome man, but the moment he finds his little sister, he turns into the ultimate overprotective brother. Someone mocks Si Qing as weak and useless, and Lu Jin beats them into a pulp the very next second. When his sister casually mentions she needs a rare crystal core, the big shot searches all night and delivers one to her. Before the apocalypse, Pei Zeli was a powerful figure in Beijing's elite circles. After the apocalypse, he's someone no one dares to provoke. Yet when a zombie horde surrounds the city and danger lurks everywhere, he always keeps Si Qing safely behind him. Who dares mess with my precious girl? Are you trying to get yourself killed?! Everyone agrees: Whatever you do, don't mess with their precious Si Qingning. Her whole family has her back! Reborn, Si Qingning decisively cuts ties with the Si family. She tears apart the fake innocent and kicks her hypocritical foster brothers to the curb. She wants to see how the three Si brothers will survive to the end this time without her. Her space keeps leveling up and growing bigger, allowing her to stockpile vast quantities of supplies. She takes everything she can get. What? The little sister, who looks so delicate she can't even take care of herself, is actually a top-tier powerhouse! All the mutant beasts obey her commands. Reborn, she finally lives the life of a winner!
