Museum security guard Xiao Que accidentally activates the "Wanjie Sign-in System". Sign in at a designated location every day to receive heaven-defying rewards such as exercises, artifacts, and skills. He originally hid his strength due to a mysterious incident in his childhood. Starting from signing in the bronze tripod in the museum and obtaining the "Xuan Gong of Taichu", he gradually unlocked the seals in his body. In the process of dealing with changes in cultural relics, responding to provocations from wealthy families, and revealing ancient secrets, he used the disguise of "the best security guard" to crush all arrogant people. As the sign-in locations expanded from museums to shopping malls, hospitals, and islands, the system rewards became more and more astonishing. Xiao Que not only revealed the cause and effect between himself and the ancient immortals, but also set off a fantasy storm in the city that "mortals can also prove the Tao", and finally reached the pinnacle of the world with the power of sign-ins.
