While howling frantically, the soul was bumping his head against the glass wall, which did nothing more than draining his own strength.
The maniacal struggle lasted for about ten minutes before the soul quieted down. He then lay still on the floor face-down as if he died for a second time.
However, an undead soul was only considered eliminated once the negative energy inside it fully vanished, which was obviously not the case right now.
Outside the glass chamber, Angor kept observing the energy reading in the environment while taking notes.
He saw the negative energy inside the test subject destabilizing very fast. At the same time, a new type of energy was slowly showing up and was gradually taking over the soul's form.
Angor was a bit confused to see two conflicting types of energy existing in harmony. This was also what he observed from the Goman King's daughter, whose face was divided into two halves after being shot by a white bullet.
