Huilan Cloud Workshop is so poor it is barely able to make ends meet, yet Tuan Jiu, the rain cloud inside the workshop that is the only one able to participate in the cloud trial assessment, is nothing more than a super glutton who only eats, never rains, and occasionally fakes illness. Within three days, if Tuan Jiu cannot complete three qualified cloud rains, the cloud workshop's cloud path will be frozen, and even the roof might be taken away to pay off debts. Qu Yanmian, a odd-job worker with a weak spiritual vein who is not even good at riding the wind, was "forced to press his seal" by a single drop of Tuan Jiu's water, inexplicably becoming a temporary cloud envoy.
