Chen Chusheng, Su Xing, Wang Lixin, and Zhang Yuan form the Brotherhood of Laihuo. They will receive invitations to "blind work" from five cities full of fireworks, and there are unknown "blind work tasks" hidden in these cities. During this work trip, they searched for "blind work clues", completed "blind work tasks", and felt the historical heritage and humanistic charm of the city. At the same time, brothers who successfully complete the "blind work" will become the current "living king" and receive rewards.
