History teacher Qin Feng accidentally acquired the ability to briefly project his consciousness into historical nodes. He often transformed into a teacher to celebrities of all ages, teaching them knowledge and skills and guiding them on their life paths. Every time he left, he told the students not to disclose their information and to clean up their traces. However, historians of later generations pieced together a shadow with "a vague image, a sea of wisdom, and seems to run through history" from ancient books of different eras. They call them "teachers of history." When Qin Feng returned to modern times, he was shocked to find that the nonsense he said to escape was regarded as a philosophical classic; the symbols he drew casually became a totem of mysticism. The whole world is studying "him", and every new mission he undertakes is like adding a new footnote to this "super vest" that will be endlessly imagined by future generations.
