My Parents Are Gone, Leaving Me a Little Sister in Siheyuan. I Have No Way Out

His parents died saving people from a fire, and the whole courtyard has its eyes on the compensation money. The beasts of the courtyard hold a late-night meeting: “Give up your job slot, let us live in your house, and hand over the money for us to manage. It's for your own good!” Lu Shi looks at his frightened, sobbing little sister and grips the kitchen knife in his arms. Back down? Six-year-old Ruru is behind him. There's nowhere to retreat! “System activated: telekinesis, super-soldier serum, pocket dimension, granted!” He laughs. Back down? There's nowhere to retreat! His parents are barely cold in their graves, and wolves are already at the door. His sister trembles, clutching his clothes. Then they'll fight! The kitchen knife flashes, cleaving Jia Dongxu's padded jacket in one blow! “Anyone else who comes closer gets cut down!” The entire courtyard falls silent. “From now on, I have one rule: You can mess with me if you want, but lay a hand on my sister and I'll wipe your whole family off the map in Beijing!” Blood drips from the knife, and the whole courtyard trembles. In this hunt targeting the orphaned children of fallen heroes, hunter and prey switch places tonight!
