I am wondering if it might be possible for him to Learn a Human Tamers Skill/Ability in the future? If so then he might be able to gain the Fusion and Power Sharing Skills? PandaMan!
I really hope the panda is really as deficient and low talented as the lady said. So sick of the cliche 'it appeared weaker than the rest but actually had a powerful hidden bloodline to awaken'. Just give the MC a low talent but hardworking pet that his cheat is perfect for raising please.
