"If the apocalypse comes and your wallpaper character appears beside you to protect you, how long can you last?" When Luo Jiajun, whose computer wallpaper was a bikini-clad image of dozens of female game characters, saw this post on a forum, his expression gradually became comical. Soon after, a post-apocalyptic game that suddenly appeared in Luo Jiajun's mind gave him the right to answer this question based on his own experience.

Luo Jiajun: "The apocalypse version keeps updating and getting stronger, right? All sorts of disasters are bombarding us, right? Just wait!

The general plot (spoilers included): The male protagonist, Shen Qiyu, is a master fish farmer, master of hatchets, and a master of multitasking. A time traveler and a reborn person (wearing a body), he's died 9,999 times? Each time as a hatchet, which further solidifies his determination to start a harem (reasons: 1. Ending the cycle of reincarnation, 2. Saving girls with personality flaws, etc.). The male protagonist's cheat codes: 1. Rapid "unity of nature" (extreme focus on tasks). 2. Nearly omnipotent skills, allowing him to know future events (he learned this after living for 10 to 20 years before being hacked). 3. Buggy-level physique (a must-have for a time traveler with a harem). 4. The sole male heir to the Shen Qi family, the head of Japan's seven major financial groups (with a step-sister who's obsessed with her brother). The story begins with the male protagonist transferring to a new school and entering his third year of high school. He foreshadowed several female protagonists as a child; he transferred schools multiple times in middle school, planting "seeds" in their hearts. Furthermore, through these transfers, he instilled "guilt" in two teachers during his first and second years of high school. Afterwards, he uses his superb experience of being hacked and his skilled scumbag skills (breaking the heart's defense, closing the distance, high-end pulling), to control the heroine's love, and force the heroine's emotions, increasing her guilt and her ability to accept the harem, expanding the number of women, and working hard to expand the harem to avoid being hacked...
