Under Ji Chen's efforts, the empty cavity continued to expand. It grew from the size of a one-story house to the size of a basketball court, then to the size of a soccer field.
What appeared before them now was a vast underwater space spanning thousands of square meters. It was filled with air, with a thick layer of seabed mud below. Though no sunlight penetrated due to the depth, rendering the interior dim and dark, the view from inside was the same pitch-black seawater.
However, without a doubt, with some additional light sources and the construction of houses from available materials, this place could become a habitat for land dwellers.
Yet, Ji Chen was not content with this. He continued to expand the space. While billions of tons of seawater could crush any living being, under the drive of oceanic authority, it compressed outwardly, creating a space deep in the ocean floor, enough to constitute a small world.
