Molecular Manipulation

Molecular Manipulation (分子操作) is an Extra Skill created by Rimuru's Great Sage who used Unique Skill Degenerate to fuse the Extra Skills Water Manipulation, Fire Manipulation, and Combustion, resulting in the acquisition of the Extra Skills Black Flame and Molecular Manipulation.

Effects
It allows the user to manipulate the surrounding magicules to control the paths of molecules in the air, creating heat from the resulting friction. By using more force, you could increase the level of temperature significantly. It can also be assumed that it possesses all the effects of the Skills it was fused from. In addition, it seems to possess a telekinetic effect, showcased by Rimuru when he moved around a ball of honey when Milim came to Tempest for the first time.

Further Evolution
After obtaining Magic Jamming from Charybdis, Rimuru (or Great Sage) used the Unique Skill Degenerate once again to fuse it with Molecular Manipulation, resulting in the Extra Skill Magic Manipulation.
