Product of Ghost Qi

The pair of eyes had completely changed as even the mere presence it exuded was staggering. Moreover, it had become one with the Blinded Ghost, no longer getting damaged even when it was being used to look around.

One of the reasons the Blinded Ghost was always on the hunt for eyes was because it was innately blind. And, it had to steal the eyes of others and use them to see. But, every time it used a pair of eyes to see, the eyes would get damaged while it would have to expend some Ghost Qi in the process.

Some eyes lasted for a day while most fully shattered within a quarter of a day or even earlier. So, if it didn't wish to remain blind, it had to search for a suitable pair of eyes to steal. And now, having done something to the pair of eyes on its centre, it had changed its inherent nature.
