A sudden collapse of the ground sweeps Han Lichuan into a survival world overrun by demon beasts. While everyone fights over resources, he awakens the unique talent of "Hundredfold Rewards," multiplying all gathering, kill, treasure chest, and quest rewards by one hundred! From a drafty shack to a fortified stronghold, and from a small courtyard for two to a survival city, Han Lichuan joins forces with Xu Chenghe, who possesses the ability to "Sense Resources," to survive together. They fight monsters, level up, build towers, and defend their city, growing stronger through trade competition and leaderboard battles. Each wave of beasts grows more ferocious than the last. What Han Lichuan must protect is not just his own life, but also the home the two of them built with their own hands.
