This isn't groundless worry, at Shuixi Middle School Lin Ma had witnessed unmanned drone swarms protecting the airport and driverless pocket tanks. They also had to consider whether the experimental human NPCs on the ground possessed combat abilities, whether the Hope was armed, and whether its crew was armed.
Maya went alone to the U-shaped highway and climbed up a signal tower, where she silently observed zombies and NPCs through binoculars. The zombies and NPCs showed no sign of understanding, but Maya in turn spotted a twin-propeller fixed-wing aircraft flying in from above the sea. After the aircraft landed, it rolled into Hangar One, and before long, the pilot left the hangar.
Maya thus confirmed that this aircraft was operable. Moreover, about ten minutes later, two NPCs dressed like ground crew drove a fuel tanker into the hangar.
Maya contacted Lin Wu through the earpiece, and he, who was napping, asked, "Is there a chance?"
