Testing the poison needle hidden in the watch is out of the question, but these glasses must be tried.
Yang Yi picked up the sunglasses and put them on, then he realized they were actually quite normal, so he asked curiously, "How do they work?"
Mike said in a grave tone, "The sunglasses function the same as normal glasses but are suited for different wearing scenarios. Eight miniature drone cameras can transmit the captured images to the glasses. First, pick up a drone and press it twice lightly."
The drone was the size of a one-dollar coin, about one centimeter thick, with rotors roughly the size of a dime. A slender frame within the circular border held the rotors in place, and there was a small protrusion on the frame. After Yang Yi pressed it twice, the drone's rotors immediately began to spin.
