It wasn't as if Jiang Chen had never considered these reasons. Although certain parts of the explanation sounded reasonable, once those empyrean cultivators had entered Myriad Abyss Island, they'd turned it into their paradise, a forbidden area cut off from the rest of the world. Thereafter, they had never paid any attention to the world around them, showing no interest in matters unrelated to their island.
As a result, a problem more or less arose. As the heavyweights of Myriad Abyss Island continued to hole themselves up in the island for increasing periods of time, they gradually distanced themselves from the outside world. Unlike the heavyweights of the ancient era, they no longer felt the same sense of responsibility. If it had been those heavyweights from the ancient era who had protected their home up until their dying breaths, they would never have abandoned their homeland just because they had found a plot of pure land.
