章 73: Chapter 65: The Cryogenic Field (Please follow for more)

Lynn's gaze swept over the ten level-one magic spells, and after some hesitation, he chose "Frost Touch" as the object of his modification.

The principle of this magic was also quite simple: it involved controlling the moisture in the air, making it cool down and condense to interfere with the enemy, but its role in combat was very limited. If it weren't for the fact that this spell had an advanced version, "Frost Domain," probably few would be interested in learning it.

Lynn had no plans to learn it either. Instead, he prepared to transform it based on the principle of this spell—by using a different element to cast it!

The element he had selected was... nitrogen!

In the Wizard Land, this element was referred to as "Seru." In Kro's manuscripts, it was even categorized as a useless element...

Considering that nitrogen is an inert gas that generally doesn't react with other substances, it was normal for some wizards to completely overlook it.
