One-hundred percent?! Seeing the result, Zhao Yu could not help but be rather excited. To think he had obtained a perfect completion rate? Also, he had gotten five items as well! Just what kind of powerful item was it this time? He immediately checked his inventory, and saw that the five new items were called long-term detectors.
"No way? Long-term detectors. What’s that?" Zhao Yu wondered. Clicking on the summary, the system started its introduction, "This item is a first-class item, an upgraded version of the invisible detector. After use, the effect is half that of the invisible detector, but it lasts ten days."
Oh, an upgraded version of the invisible detector? Zhao Yu thought back before remembering that the invisible detector was an anti-surveillance device, used to detect any sort of bugs, recorders, cameras, trackers, etc, as well as explosives. No matter what it was, the invisible detector could very accurately detect those things.
