Jiang Ye wandered to an isolated island cut off by the river, with only a mobile phone that was soaked in water.
He soon discovered a strange thing: whenever he sincerely helped the islanders solve a problem, he would see a number appear above the other person's head.
The next day, the number would be turned into money and transferred to his shabby bank card.
What's even weirder is that the money can only be spent on the island: repairing piers, building water towers, building health stations...
