With their help, the laboratory's research expanded beyond simply dissecting Eye Demons to map out their internal anatomy.
There was also a breakthrough in the research on the Eye Demon's ability to grant attributes to its host.
This was primarily due to the Eye Demon's special mimicry ability, which allowed it to become a complete part of its host. Once it had merged with the host, its own attributes were naturally shared.
However, due to some unknown rule, this method of attribute stacking could only raise the host's attributes by a single rank.
If the host was a hero-rank being and the Eye Demon was not, the Eye Demon could devour and replace matter within the host's body to temporarily elevate itself to the hero rank. Furthermore, the longer it remained as a parasite, the more likely the Eye Demon could truly advance to become a hero.
This was the most convenient and common way for an Eye Demon to advance to the hero rank.
