Sublessor Lin Qi specializes in remodeling old, rundown houses in prime school districts, building a high-end benchmark for accompanying students through sheer hard strength. When greedy landlords breach contracts and provoke him, and capitalist developers crush him aggressively, he uses rules as his blade and the warmth of the mortal world as his shield, counterkilling step by step. From malicious harassment to public opinion framing, he guards the contract and the warmth of the marketplace, ultimately leading to the collapse of capital, the return of human hearts, and achieving a school-district housing legend.
