After going through the baptism of countless planes, Zhao Hai understood that in order to make a space the same as the outside world, he had to try his best to bring everything from the outside world into the space. Even the most inconspicuous things had to be brought into the space. It was because these things formed the natural environment of the outside world.
Therefore, if Zhao Hai wanted the space to be the same as the ocean outside, he wouldn't just take in fish. He would take in seawater, soil, rocks, corals, seaweed, and everything else. Because of the palace of nature, his space already had an ocean. Now that he took all these things into the ocean, he could naturally make the ocean in his space more lively.
As Zhao Hai was putting things into his space, a huge fish approached him without a sound. Zhao Hai didn't even notice it.
