The Eighth Technology Revolution

The effect of mastery spells varied wildly, and not all the mastery spells were area-of-effect spells. Only high-level mastery casters such as Michaux could master such powerful spells. 

On this planet, other than Wang Tong, the only other person who was capable of expanding one's elemental attribute was the young master of the Divine Mastery Sect. 

It was impossible for any METAL warrior to get close to the Zerg lord due to his guards, but Michaux was not a METAL warrior.

Michaux's fingers knotted into a mastery sign that held the power of his spell, managing to lock onto the target using his soul energy without being noticed. Lie Jian continued to bombard the Zergs at the cost of huge consumption of his soul energy. Only the most aggressive attacks could attract the Zergs' attention. Luckily, the Zergs wanted to capture Lie Jian alive; therefore, he hadn't met with any life-threatening attacks so far.
