Bai Ziye, an ill-fated person, made his way to the city to seek his fortune with help from the village chief, a man renowned for his virtue. He thought his ability to identify medicinal ingredients would at least help him make something of himself, but without a professional license, he could only join the army of food-delivery couriers.
Then, while making a delivery one day, he encountered a sinister entity. By a twist of fate, he ended up joining Bureau Seventeen, a government agency.
