Adrian was following the path beside the river with the silver-winged tiger cub in his hand. Luckily for them, they hadn't encountered any magical beasts along the way. Well, it wasn't so much luck as it was the claw that Adrian was wearing around his neck like a necklace.
Before she left, the silver-winged tiger broke off one of its claws and gave it to Adrian. It knew that it would be hard for them to leave the inner region, given how weak they were.
Therefore, it infused its aura into its claw before breaking it off and giving it to Adrian. The claw that possessed the aura of the Rank 7 silver-winged tiger worked like a talisman that warded away all beasts from them.
It was her final gift to Adrian and her cub, to make sure they left the Msity mountains alive. However, it wasn't a foolproof method. The piece of the claw was not large, only small enough to serve as a necklace.
