To sum it up, it boils down to the same principle as making the simple excavators and Douzi Cars work; it's a matter of human nature. Although Yan Fei has grown and toughened up quite a bit over the years, he still doesn't give these issues enough thought.
Of course, most of the time, having developed to the current stage, it's okay even if he doesn't think things through completely, just like the current situation. If he bluntly saw which village wasn't putting in the effort and was dawdling, he could directly send them away without anyone being able to fault him for it.
But now that there's someone who can help him spot and fix oversights, to make things better, why wouldn't he be happy to do so?
