It had to be remembered that Ryu didn't know much about the various beasts on the Mortal Plane because he never had to care about them. But, when it came to high level beasts or creatures like this, his knowledge was very deep.
There were no shortage of Ruins that had such guardian beasts. Humans had among the shortest lifespans of all creatures in existence, even if one counted those with exceptionally high cultivation. So, using such beasts and creatures as guardians was best as they would last a very long time.
