Deep down, William was a little scared to get closer to the mermaid. Even though she seemed friendly, she was still a creature guarding the portal — meaning she could be dangerous.
Rena felt the same way. As soon as he started walking toward the mermaid, she grabbed his arm, holding him back.
"Relax. I'll be fine," he said as he turned and looked her in the eyes.
Reluctantly, she let go of him, even though the worry didn't leave her expression.
As William got close enough, the mermaid reached out and gently took his hand, examining the ring he had received so long ago from the Triton King.
Using the ring to open a portal to the mermaid's realm was impossible. The dungeon itself blocked that kind of usage. And even outside, on the demon island, the power of the ring had also been sealed.
William couldn't even use his SSS-rank skill to open portals for some unknown reason.
