There aren't many fierce beasts and evil beasts undergoing transformation in the lower levels of the Forbidden Land.
Lu Xuan begins to raise them one by one, meanwhile learning detailed information about each evil beast and fierce beast.
He fuzzes up the information he's gathered, recording it as guesses and estimates.
From his entry into the Sky Sword Sect till now, Lu Xuan doesn't mind showing his talent in Spirit Plants and Spirit Beasts.
His quick rise to power and status was all based on his accomplishments with Spirit Plants and Spirit Beasts, which everyone in the Sky Sword Sect watched.
For other Cultivators, having a colleague with in-depth knowledge of Spirit Plants and Spirit Beasts does not pose much of a threat. Instead, they can cooperate with such a person and gain numerous benefits.
