This is the weapon that the Fearless Mechas have created for killing insects in their long battle against the swarm. Even though the surface of the sun is only over 6000 degrees, they can mass-produce a sea of fire reaching nearly ten thousand degrees through special arcane technology.
The fire wave can even last for several hours, as long as their energy and fuel are not exhausted, flowing endlessly. The flames cling to the organic matter like maggots on a bone, burning continuously until everything is incinerated.
Only at this temperature can the corpses of the swarm be decomposed, preventing pollution and distortion from affecting the surface.
The so-called scorched earth strategy is to use these flames to burn away all traces of the swarm on the entire planet, decomposing them into their most primitive structure within the fire.
Eggs, corpses, slime, and anything else are purified in these flames, and the entire surface burns into a layer of obsidian and glass.
