Especially the fungal mat in contact with the metal surface inside the Mechanical Race city.
The fungal mat advancing with the Insect Race spread forward, gradually withered, dehydrated, and deactivated under the heat that could cause an entire district to begin to warm, eventually igniting.
Even though the Insect Queen constantly increased the nutritional supply to the fungal mat, it could only just balance the growth rate of the fungi with the rate of loss.
If the supply of nutrients were slightly delayed, the fungal mat would instantly be burned to ashes by the high temperature conducted from the metal, no longer able to provide continuous nourishment for the Insect Race at the front line.
This was not just a trouble blocking the Insect Race from advancing further.
Beyond these high temperatures already impacting the environment on a large scale, some Mechanical Race buildings not made of White Cloud Steel Alloy even began melting.
