Zach wondered whether the pirates were truly this weak or if there was some reason behind it. After careful consideration, he believed that there was only one hypothesis that could explain everything.
The reason he had been able to penetrate into the heart of the island so easily wasn't because the opposition forces were weak. It was just that they were too lacking in terms of numbers. The individual capability of each pirate wasn't lacking at all. They were skilled in battle and had probably gone through various life and death situations along with their captain.
Moreover, some of the pirates just stood by and raised their hands above themselves in surrender as if they had no intention of fighting his forces. It looked like they had given up on resistance after seeing the attitude of their cowardly captain who ran away by himself in tough situations.
