Yue Feng's off-the-cuff theory wasn't purely fabricated, but was instead an advanced form of lying and deceiving.
Half-truths, half-fabrications!
For instance, the signs of fish Yue Feng mentioned, like fish stars, fish bubbles, or the color of the water, could actually enable a seasoned and sharp-eyed angler to make certain judgments.
But to say there are structures underwater and that there are subtle differences in the ripples on the water, that's a stretch. Even if that were true, it's not something one could observe with the naked eye. That's unscientific!
However, Yue Feng, by demonstrating the fishing techniques live, greatly enhanced the persuasive power of his explanation, and Captain David believed at least a great deal of it.
Based on Yue Feng's explanation, Captain David scrutinized the spot in front of him for a long time, but since he couldn't spot any difference in the ripples, he just shrugged his shoulders helplessly and gave up trying.
