Because of this ability, the mermaid's natural ability to recover her energy was also faster than other people, which means the mermaid was almost like a long-lasting power bank.
The Merfolk race was such a terrifying race that many big races didn't dare to offend even if they united as the people on the land precisely because of these 'mobile banks' existence.
It was indeed common for many Merfolk races to awaken the energy recovery ability instead of other abilities, but they were not treated badly by fellow race members at all.
To be honest, these 'power banks' were all protected by the people of each tribe because their existence was super important in the continuous sea wars over thousands of years.
Even though nowadays, underwater countries were more peaceful than before and there were only small conflicts with sea beasts and monsters without any conflicts with fellow Merfolk race...
