OP Reward!

Sensing her precarious situation, the Mermaid suddenly started glowing a bright blue as she began using an incredibly powerful skill.

The water at her tail started billowing as if alive, moving in a circle and erupting in the air at times. Jack's face tensed as he saw her raise her delicate hands. 

With her gesture, a gigantic tidal wave rose up. It was even higher than the town wall! 

"Oh god!." Countless exclamations of disbelief were heard. 

It seemed like she was really pushing herself to the limits, all for her revenge. Her body was trembling, but she didn't care. She wanted him dead! 

As soon as she released this skill, they would all die, perhaps even the players fighting in the back. Many shook, hesitating between running now or running later. 

As for confronting it head-on? They weren't dumb! 

"Guys, NOW!" Jack screamed at the top of his lungs while waving.
