As Rank Es Elementalists, they were directly using the surrounding energy, instead of storing the energy inside their body first so that they could use it for later. That was why inside the Separate World, there was little energy to get from.
Old Maytan would not last so he looked at the three and asked to get the energy from them.
The three had no choice but to channel it to the old man.
Feeling chaotic inside him as Fire Elemental Energy clashed with his World Element, Old Maytan immediately redirected it to his elesp.
The aura of the barrier soon changed and a tinge of redness spread all throughout the sphere.
The Apexial Beasts who thought that they were about to destroy the barrier frowned. They attacked more.
Meanwhile, Sheran was feeling the energy moving into her. It was not raw energy but instead, Natal Energy. She felt full. This is because Gamon and Old Maytan's Natal Energy entered her energy veins, trying to poke holes in them.
