Elemental wizards were the most powerful system in the wizard world. This was acknowledged by all wizards.
It was not that elemental wizards possessed power that crushed everything, but that they had the most comprehensive and orderly systematic classification for energy manipulation. Every rank of elemental wizard would develop abilities and methods corresponding to that rank, thereby producing the formidable power to pry at the rules of all things.
Wizards of other systems, and even those creatures from other worlds, could only be said to possess combat power comparable to elemental wizards of a certain rank, or to control energy at a certain wizard rank. They themselves had no standardized classification of energy-control levels.
For example, in the Dark Well at Zelato Harbor, Green had once encountered a star-like creature that called itself a fourth-rank Star Spirit of World-Star World, yet the energy it could control lay somewhere between that of a second-rank wizard and a third-rank wizard.
This so-called "between" arose because the way they increased their power was like passively evolving, endlessly raising their physical attributes. This made them rely on physical attributes to fight wizards—a gradual evolution.
It was unlike elemental wizards, whose differing ranks brought distinct special abilities and whose levels were strictly defined: first rank was first rank, second rank was second rank.
Perhaps a fourth-rank Star Spirit and a fifth-rank Star Spirit merely differed by a few points of attack power, with no actual difference in combat strength at all.
Yet according to the Wizard Continent's standards, such a creature possessed the combat power of a second-rank or third-rank wizard.
For half a year, Green had spent all his time in Mentor Peranos's laboratory.
During this period, Green had not spent all his time studying the wizardry knowledge of Mixed-Poison Body Refining. He had
