Kapitel 950: His Current Biggest Weakness.

"I also can't wait to master external manipulation." Felix affirmed with an eager expression.

Ever since Felix obtained lightning manipulation, he never touched its external manipulation since it was always sealed.

The few lighting abilities he could use with external manipulation, were summoning a thunderstorm, parasitic discharge, and transmutation!

"Alright, settle down." Jörmungandr's eyelids twitched, "You still have to keep focusing on your poison manipulation."

Now that both lightning and poison manipulations were fully unlocked, Felix could learn them both simultaneously.

"Of course...With my current experience, it won't take me long to learn the same external techniques and master external manipulation." 

Since most standard techniques were more or less the same for most elements, Felix knew that he wouldn't struggle in lighting manipulation the same as he used to in poison manipulation.
