The Myriad Worlds Shop: A Scumbag's Road to Redemption Across the Heavens

From the start, after transmigrating, I'm a wife-beating scumbag whom everyone despises. I raise my hand to hit and curse my wife, and coldly let my four-year-old daughter go hungry and freeze. My wife and daughter are covered in bruises and skin and bones. Worse still, my daughter has developed a malignant tumor caused by malnutrition, and her life hangs by a thread. After receiving the original owner's memories, I vomit uncontrollably, disgusted to the extreme. Thankfully, at the brink of despair, I activate a small shop anchored to the Myriad Worlds. The dilapidated, bankrupt corner store connects to ten worlds, including the apocalypse, cultivation, high martial arts, and elves! One pack of instant noodles in exchange for a high-grade mutated crystal core from the apocalypse! One sack of ordinary rice in exchange for an ancient treasure from the primeval wilderness! From then on, I'm ruthless to outsiders and decisive in killing. Scummy friends, creditors, and snobbish relatives: anyone who dares provoke me gets wiped out. But for my wife and daughter, I give them everything and love them with all my heart, helping them heal. The good-for-nothing scumbag everyone once despised will eventually rise to the top of the Myriad Worlds and protect the only warmth left in the human world!
