My sister regrets her marriage and climbs the ladder? My sister will become eighty rich if she marries me!

After dying on his sickbed, Lu Qingshan is reborn and returns to the Northeast forest region of China in the 1980s. In his previous life, he mistakenly trusted a manipulative woman who broke off their engagement, ruining his future. Determined to change his fate, he immediately proposes to his beautiful but mistreated older sister, Xiulan, declaring her rejection of another suitor as a blessing. "Breaking off the engagement? This is wonderful news! From today on, Xiulan is my wife!" Armed with thirty years of experience from his past life as a mountain hunter, Lu Qingshan navigates the vast primeval forests with ease. Wielding a hunting knife and a rifle, he hunts for precious ginseng, battles wolf packs, captures gold smugglers, and even subdues a tiger king. Starting as a despised poor boy in the village, he systematically outmaneuvers his rivals and leverages his knowledge of future events to accumulate wealth during the early economic reforms. Lu Qingshan builds a luxurious home, drives a jeep, and sells mountain goods to provincial cities, transforming his family's life from poverty to prosperity. He dotes on Xiulan, turning her from a suffering woman into a pampered princess envied by all. Meanwhile, the younger sister who once rejected him for a higher-status match is filled with regret. She tearfully begs for reconciliation, claiming she had her reasons, but Lu Qingshan coldly dismisses her with a single word: "Get lost!"
