Infuriated after seeing his woman acting snug with her much older superior, Lin Hao decides to confront the fraud.

Brimmed with rage and other unresolved emotions, his subsequent actions could be considered stupid but brave. Instead of obtaining reprisal, he is thoroughly hammered by the fellow who happens to be a big shot. He is hit on his head in the ensuing brawl, leaving him in a daze.

As he recovered on the following days, he is puzzled as to why he kept seeing a floating monitor’s screen on his line of sight. Lin Hao decides to visit Lin Hai People’s Hospital, the Department of Ophthalmology to better figure out if he was hallucinating or crazy. He is threatened to be locked up for being a crack head by the Director, prompting him to flee to the streets.

Lin Hao is unaware of the advantages and mysteries surrounding the cryptic monitor until he encounters a few tragedies. He gets into a confrontation with a few brawny men for saving a damsel, but instead of being beaten, the monitor helps him dodge attacks by giving him warnings. Although baffled by the monitor now more than ever, he went along with its forewarnings until he trounced the attacks.

To show her gratitude, the damsel takes Lin Hao to her family’s shop in the Ancient Antique Street. Prevalent for being a treasure trove, the Antique Street was shared amongst sixty-eight rich and powerful families. Surrounded by antique treasures, the floating monitor in his line of vision proves to be more useful than Google. As long as he stared at something, its full information and approximate price would display on the monitor’s screen. The newfound aptitude was a fraud-proof method for exposing swindlers. As expected, his talent does not sit well with the rest of the families, which lived by selling fake treasures exorbitantly. Just as quickly as he got rich, he made powerful enemies whose main agenda was to kill him.

How much further could the mysterious monitor continue protecting him?
