This was a considerably large Space Fragment. Although Chen Yu couldn't precisely determine its size, the sight of at least a few hundred meters high mountain peak inside the Space Fragment made him realize he had hit the jackpot.
This mountain peak must have once been an island rising from the seafloor, as breakage marks could still be seen at the base of the mountain, with traces of sandy beaches remaining around it. The mountain took on an L-shape, with a main peak several hundred meters high and branches extending out for several kilometers on either side. Between the two branches lay a not-so-small plain valley that looked to be formed by river alluviation, and even a dried-up riverbed was visible on the plain.
However, there was no longer water on this land; the soil had long since cracked, and all plants and animals had long since perished, leaving no trace.
