Su Hao transmigrated and obtained a check-in system. Every day he checks in, he gains check-in points and random rewards. Initially, Su Hao wanted to be a low-key check-in person, living a carefree and dandy life in this world. But his strength wouldn't allow it! First check-in reward: 5 cubic system space slots, one Li Xunhuan possession card, and double check-in points.
