The Five-Colored Spirit Lizard crawled past his fingertips, wagging its long tail as if to please him, and swallowed a Jade Pearl. Zhang Yan's gaze followed it all the way into the cracks in the cave walls, and he smiled slightly. With these spirit beasts kept in his Cave Mansion, they could catch flies and eat insects, sweep away dust and grime, and keep venomous snakes and fierce beasts from approaching. They only needed one Shell Pearl for nourishment each year, making it quite cost-effective. However, what left him feeling regretful was that any living creatures of this kind could not be reflected in the Broken Jade.
Compared with these spirit beasts, Tang Yan and her group on the Northern Island, to him, were utterly useless, not even worth the bones of a fish.
