Xie Yin, a social animal researcher, took a nap while fishing at work, and woke up in a different world. Not only did it turn into a round skull, but it also accidentally activated the magical "check-in system". The system told him that he was responsible for collecting information on the world's customs, customs, scenic spots, humanities and history through "check-in" to improve its intelligence. Only in this way can there be a chance to go home.
However, in addition, after becoming a skull, he has another side task - to fight for himself. It is said that his limbs were dismantled and scattered all over the world... Therefore, in order to return home intact, Xie Yin had no choice but to embark on a journey around the world and put together his own journey.
Motto: A journey of a thousand miles begins with a single step
