Xu Xiaoxiao was not a fool and wisely kept his mouth shut.
Suddenly, Zhou Hengyang flung the door of the speeding car open.
He anchored himself to the car's frame and held himself aloft using the strength of his legs. Leveraging his weight, he swung himself atop the car.
"What are you doing?!" Xu Xiaoxiao cursed fiercely. Alarmed, he almost slammed on the brakes. Fortunately, his reaction time was impeccable, and his motor skills were stellar.
If he had stepped on the brakes, Zhou Hengyang would probably have shot off the roof like a pebble released by a slingshot. Keeping his speed constant allowed Zhou Hengyang to climb onto the roof of the car without much issue.
