Reborn in 1978: After cutting ties, I kept my sister well-fed and warm through the bitter cold

Lu Yuan was reborn into 1978—the very day his cruel stepmother was selling his younger sister to an old cripple from the neighboring village! In his past life, he had been powerless to stop it; he could only watch helplessly as that old man dragged his sister away, leading to a tragic end where she suffered endless torment before dying in childbirth. In this life, burning with rage, he kicked his vicious stepmother aside, scared off the shameless old cripple, and resolutely took his sister away from that predatory, soul-crushing family. Amidst an era of scarcity where food and warm clothing were luxuries, and with a once-in-a-century "super cold wave" fast approaching, Lu Yuan relied on memories from his past life. He hunted in the mountains, fished in the rivers, and—following the strategy of "digging deep tunnels and storing grain"—frantically stockpiled supplies for the winter. When the terrifying cold wave struck, leaving the entire village shivering in the freezing wind—with white mourning banners hanging from every home and families draped in funeral cloth—Lu Yuan, his sister, and his sister-in-law were safe and warm indoors. Wrapped in sable furs beside a glowing charcoal fire, they feasted on roasted meat and sang songs. Once the cold wave passed and the villagers rejoiced at having survived the ordeal, Lu Yuan seized the opportunity presented by the winds of Reform and Opening Up. He soared to success, making waves in the new era and reaching the pinnacle of life!
