Breakthrough (R-18)

After comprehending the lightning element, he dries his body and then sat on the ground. He didn't wear anything except for the underwear so that he won't destroy another pair of clothes. He closed his eyes and slowly focused on Lightning Element.

To sprint into the Qi Condensation Realm, he must condense a bead-filled with elemental qi. He took out a few normal essence stones. He could use the lightning element stone but that would only make him rely less on his element.

After all, the lightning element stone isn't pure lightning qi. And, only those people who have touched the elemental control rather than elemental transformation use the elemental essence stone.

He has already comprehended the lightning element so it doesn't matter to him. He could simply focus on making the lightning qi as pure as he could. Because the qi transformation can be impure by the amount of qi transformed into the element.
