Frozen Sihe: Billions of Materials, Exploding and Renovating Safe Houses

Once reborn, back to 1965, on the eve of the frozen doomsday. Li Han opened his eyes, and the bone-breaking pain of being eaten by the beasts and neighbors in the courtyard in his previous life was still clear. The sanctimonious hypocrite, the pitiful Bai Lianhua, the good brother who stabs in the back... The kindness in the previous life was rewarded with being used as a reserve food. In this life, he returns with a doomsday system worth billions of supplies! While others were still worrying about a mouthful of stick noodles, he silently transformed his dilapidated house into a steel fortress with iron walls! While the animals in the courtyard were shivering in the extreme cold of minus 70 degrees, his fortress was as warm as spring and filled with the aroma of meat. You bastards who devoured me alive in my previous life, in this life, I want you to kneel in front of my door and beg for mercy! When the end comes and morality declines, I, Li Han, am the only law in this courtyard! This novel and its characters are purely fictitious.
