Spirit Tiger

Linghu was originally just common spirit demon, and there was no memory of inheritance. Even if he later practiced "Taixu Lei Jue", he would just cut the marrow and exchange blood and improve his physique.

Just by accidentally getting four bone claws, he accidentally incorporated four bone claws of unknown origin into his body. Linghu blended into the four claws of the ancient tiger, and was able to reborn, cleanse the bones and exchange blood.

But after he break through the Inner Core Realm, Linghu's perception receives some kind of inheritance!

This kind of inheritance comes from the four ancient tiger's claws!

The four ancient tiger's claws have been integrated into the Linghu's body, and naturally the memories of them have been passed down.
