My Crazy Sister Wields a Knife, While My Black-Hearted Brother Strikes Back

[The Female Lead Isn’t a Saint, Except When It Comes to Her Younger Brother! Rebirth + Natural Disasters + Apocalypse + Pocket Dimension + Stockpiling] If you don’t explode in silence, you go crazy in silence! A deranged, ruthless big sister and her black-hearted schemer of a younger brother! In her previous life, Cheng Meng struggled to survive a series of natural disasters, only to die in a fissure left by an earthquake. After being reborn, Cheng Meng’s first goal is to break the legs of her lovesick idiot of a younger brother, then tie him to her waistband. Or she could just beat him to death, burn him to ashes, and carry him around wherever she goes. That would count as doing her bit as his big sister. When she sees that 1.8-meter-tall young man looking at her with a pair of puppy eyes, Cheng Meng’s heart softens! Fine, I’ll give you one more chance! After the apocalypse begins, she looks at this freeloading puppy of a little brother who contributes nothing but companionship… Her enemies from her previous life: “What’s the point of staying alive? Let’s end it! Right now…” Cheng Meng glances at her puppy brother’s long legs. Good thing she acted like a saint for once. Otherwise, how would this little punk use those legs to run off and cause trouble for someone else?
