After World War I, Dream Island had gained a peaceful external environment for development. In such an environment, Yan Fei was not in a hurry and had ample time to produce artificial whales, thereby enhancing Dream Island's martial force.
Even without the armed artificial whales, Dream Island was not easy to provoke because the most deterrent weapon on the island was not the artificial whales but Yan Fei's drone avatars. Even if the anti-submarine artificial whale was found to lack combat power, should anyone dare invade Dream Island, Yan Fei would use his drone avatars to teach them a lesson in being human again.
