Others travel through the awakening system either in their minds or on their wrists, but Chen Yan is different - his system is bound to his feet! Travel to the world of "Spy House" and become a walking "suspicious element". Fortunately, he has a foot system to help him: his toes can hear sounds and identify his position, his soles can condense sharp blades, he can run faster than a sports car, and he can jump and walk on walls. In order to survive, he was forced to join Twilight's "Owl" combat plan, disguised as a member of the Folger family, and surrounded by spies, killers, and mind readers, used his feet to perform the most alternative undercover career. "Warning! There are enemies 50 meters ahead. It is recommended to use sprint to evade!" "Tip! Aniya is reading your mind, use your toes to kick stones to divert attention!" When feet become the strongest weapon, this spy game is destined to be won "down to earth"!
