The outer layer was made from a very strange alloy.
The alloy was very unique and contradictory. But he could see the genius behind its atomic structure.
It was artificially formed under tons of pressure that was rather inefficient and impractical but the results were amazing.
He could see that it could take a level 80 expert to even dent the thing.
The shell was also responsible for repelling null. Repel might not be the right term as it acted like an iron ring between magnets, giving a shielding to the components inside.
Null tends to corrode matter that has little to no resistance to it.
While the rest used formations to shield themselves from it, the mecha race had come up with an ingenious material that could shield them from it.
The structural integrity of this material was also leagues above any that he had seen before.
The more he looked at it, the more he wished to end this war and visit their universe.
