The ability Whale Horn Piercing Crystal would enable the whale horn to pick out the souls hidden in non-lifeforms. Lin Yuan's eyes could not help but light up when he saw this ability.
Possession took place when a soul entered another body that was not its own.
As Lin Yuan continued to grow stronger and learned more about souls, he realized that possession was not impossible.
The soul that invaded another body had to be of an extremely high level. It was difficult to tell if another soul possessed a lifeform.
Rememberling could use the ability Whale Horn Piercing Crystal to remove the possessed soul. Thus, this ability also had an investigative function.
Lin Yuan believed that the ability could be considered a key ability.
He could not be certain what dangers existed in the outside world.
