Simulating crystals were an impressive creation, which many human scholars called a miracle.

It was impossible for a human to become a rock, let alone a gun. However, simulating crystals were beyond their limitations.

As crystals, simulating crystals could mimic the characteristics of different matters, which was miraculous and amazing.

When turning into mechanics, the simulating crystals were like machines. However, when turning into creatures, they had the features of creatures. In addition, simulating crystals' abilities were similar to the simulated items.

As miraculous as it was, the simulating crystal had a fatal flaw, which was that the stronger its target was, the stronger it would be. That meant if the target was not strong enough, the crystals would be weak.
