Sea of Fire Stargate

Judging from the appearance, it was hard to tell whether the enormous object floating in the ocean of magma was a 'door' or something else.

It was a square, enormous black cube that was almost a hundred meters long. Complicated stripes and complicated runes were attached to the surface of the cube, which was also covered in rust and mildew. It was obvious that it had been sealed for thousands of years.

Even if such a metal was buried deep inside the magma, it was impossible for it to grow rust and mold.

Therefore, it was very likely that the black cube had been retrieved from another dimension.

As the scorching magma eroded its surface, the rust, mold, and even the shell carved with stripes and rune arrays on the surface of the cube were all peeled off, revealing the pure blackness inside.

When the last shell fragment was gone, what was left in front of everyone was the deepest blackness.
