章節 523: Immortal Zhenyuan Makes a Very Important Decision!

A grade eleven spell was already a major lethal weapon that could annihilate planets – Immortal Zhenyuan couldn't imagine how powerful a grade twelve spell would be.

The main reason why he hadn't been able to subdue Wind Spirit and completely destroy him was because the dark energy would double Wind Spirit's strength when he was in berserker mode.

It was hard for Immortal Zhenyuan to defend himself in pure hand-to-hand combat when Wind Spirit was in this state, and he had narrowly missed being injured during some of their fights.

It had never occurred to the red-haired young man that the dark energy could be combined with a spell to double its strength!

Worse still, he had never seen the magic that Wind Spirit was using; he had no idea what was going to happen.
