Guo Huai, an ordinary history college student, got a mysterious mobile phone in an accident. There was only an APP called "Everything Drawing Card" in the phone. This APP allows him to draw "clue cards" from any object, location or even person. Each card hides unknown secrets.
One day, Guo Huai accidentally drew a card called "Hundred Years of Wrongful Souls" on campus. A vague image appeared on the card - the last words left by an ancient man who was wrongfully accused to death before he died: "The truth will eventually be revealed."
From then on, Guo Huai was involved in a shocking mystery that spanned a century. He discovered that he could dig out the buried truth from the dust of history by drawing cards. In the process, he met Zhang Ming, a "white-eyed wolf" companion who was friendly on the surface but actually had ulterior motives.
On the surface, Zhang Ming enthusiastically helped Guo Huai, but in fact he coveted his ability to draw cards and secretly set up traps to try to take Guo Huai's ability as his own. As the mystery was gradually solved, Guo Huai discovered that this century-old mystery was closely related to the secrets of the Zhang Ming family.
With the help of his ability to draw cards, Guo Huai saved the day from danger time and time again, uncovering layers of fog, only to discover that there was a bigger conspiracy hidden behind the truth. And that mysterious card drawing APP seems to be far more than just "solving the mystery"...
