As a Wizard who follows the path of Physique Evolution, Richard has always been skeptical about the upper limit of Physique Evolution.
After all, in the Wizard Civilization where Bloodline Witchcraft prevails, spiritual evolution can become mainstream. This makes it hard not to suspect there might be some sort of flaw in this route.
This skepticism did not dissipate after Richard became a World Master; on the contrary, after he learned Life Editing, this doubt grew even stronger.
Even with the discovery of semi-illusion creatures, it was not completely erased.
Spiritual Evolution is about exploring the external world; they study the rules of this world and then leverage spiritual power and energy.
Their upper limit depends entirely on how much knowledge they have explored.
