The knowledge of the Shape-shifting School played a significant role in Richard's development of the Radiation Rule.
But this doesn't mean that Richard used only the knowledge of the Shape-shifting School to develop the Radiation Rule.
The Radiation Rule endowed Richard with the ability to release high-energy radiation, a capability that, if applied properly, could be very powerful.
Regrettably, the intensity of the high-energy radiation Richard released was excessively high, and even with his radiation manipulation, he could barely protect himself from harm.
For a long time, Richard treated this skill as Field Witchcraft.
But later on, Richard had a thought: if he couldn't contain the high-energy radiation, why not find something else to do it?
As an Alchemy Wizard, it wasn't difficult for him to create Magic Equipment to help him contain the radiation.
And so, the Radiation Gathering Cannon was born.
