Xu Dian, 24 years old, works the night shift at a convenience store and has a character as innocent as a blank slate. He believes in the beauty of the world and never puts his guard up against others. Until that rainy night, he picked up a strange old mobile phone next to the trash can.
There is only one APP in the phone that cannot be deleted - "Eye of Truth". Opening it, Xu Dian saw another world: Lao Wang, who came to buy beer every day, had blood-red lines of internal energy wrapped around his body; the homeless man who always wandered around the street corner had fatal palm prints hidden in his palms. In this city, countless martial arts masters live disguised as ordinary people.
What made Xu Dian even more horrified was that he found nine strange finger marks on the body of his neighbor Uncle Zhang - which were caused by an evil power called "Heart-Breaking Palm", but the police said it was a heart attack. Xu Dian tried to call the police, but found that he had been targeted.
At the same time, a surveillance video of him blocking a flying bottle at a convenience store unexpectedly went viral. Overnight, "Innocent Brother" became the top trending search topic. Fame brings fans, and also attracts the evil martial arts master - Yin Wuchang. This murderer, who has been practicing evil arts for decades, needs someone with a pure physique to practice the last level of evil arts.
Xu Dian was forced to be involved in a suspenseful killing situation that he had never imagined. With the golden finger in hand and his pure heart still intact, can he survive to the end in the urban undercurrent?
