When Liu Chen wakes up, he discovers that he has been bound to a general store system. By trading with others, he can obtain items such as food, water, and clothing. With the system's help, Liu Chen builds a general store. While bringing hope of survival to other people stranded on the island, the store also gives rise to new dangers.
