Insect Demons
The insects on the bodies of the three Hunters earlier seemed to be the leaders of the swarm, capable of directly activating the parasitic eggs inside these imperial soldiers, causing them to mutate into their current half-insect, half-demon form.
The imperial soldiers in this form had completely departed from the realm of humanity. It was evident from their status screens that the human attribute had vanished entirely.
Even demon races struggled to achieve such a thorough transformation of life forms. Only insect races possessed the inherent ability to assimilate and mutate their hosts to this extent.
From the previous investigation in Ilinor, Reji and the demons were aware of the widespread parasitic phenomenon in the human world.
