Chen Ye, an overworked wage slave, dies from working overtime and transmigrates to Yunmeng, a primitive tribe made up entirely of women. The tribe is on the brink of extinction: there are no men, they don't know how to make fire, and they are bullied by wild beasts and hostile tribes. Chen Ye hasn't even had time to celebrate landing in a "nest of beauties" before he realizes that although the women are curvy, they look at him like he's a walking roast.
At the critical moment, a System calling itself the "Greatest Support in All the Worlds" activates, but takes the form of a donkey. Not only is this donkey foul-mouthed, sharp-tongued, and greedy, it's also a contrarian. Every day, Chen Ye is either flirting with the women or bickering with the donkey.
What's worse, this is a tribe of the "Nuwa people," who naturally worship women. If Chen Ye wants to survive and take charge, he first has to convince the women to let him stay of their own free will. And so Chen Ye begins an exhilarating life of "building infrastructure by day and training in cheesy pickup lines by night." As technologies such as fire-making, farming, pottery, and metallurgy are unlocked one by one, Chen Ye not only turns the Yunmeng tribe into the "Greatest City of All Time," but also wins the hearts of ten primitive beauties, each with her own distinct personality, making his way from "tribal son-in-law" to "king of all the women."
