"How did you get to know Old Karl?" Allen Zhang asked with curiosity.
"I met him in a bar. When I first said I was going to sell him a plane, he didn't trust me." The old man said: "I used to work at NASA, retired for many years now, and I'm also a researcher. The micro Rocket Thrust Launcher that I want to sell you is also self-developed!"
"Where is it?"
Allen Zhang only saw the plane covered with a black cloth and hadn't yet seen where the launcher was hidden.
"You'll be able to see it in a bit!" The old man chuckled, deliberately being mysterious. Then he lifted the black cloth, revealing the two-seater plane underneath.
Allen Zhang glanced at the condition of the plane and, as expected, saw that the red and white paint had begun to peel off. A wing and the tail fin were missing, the seat and buttons were yellowed and aged; it looked more like an antique that had been stored away for too long in a warehouse.
