Through the Drone Quantum Radar, Yan Fei had discovered the Mechanical Monkey and began paying attention to its movements. Yan Fei couldn't use his equipment to conduct a detailed inspection of the Mechanical Monkey, but using the Quantum Radar to scan its shape, he confirmed it was the same one he had encountered previously in Africa. Considering the extreme combat power of a Mechanical Monkey, having even one was extraordinary, not to mention a world full of them would surely belong to its master.
As the Quantum Radar scanned, the Mechanical Monkey's head turned with the flight of the Drone, clearly capable of locking onto drones with radar stealth ability. When the Drone approached the airspace over the Underground Military Fortress, the Mechanical Monkey's eyes began emitting red light, indicating it was about to launch an Energy Beam Attack.
