Separated by a single wall.
Ian felt as though he had entered an entirely new world.
Outside the wall, the magical power was abundant but muddled, like a clamorous marketplace. Inside, it was pure and potent, and even more concentrated.
The wizard leading the way did not say a word. The two proceeded along a broad stone-paved main road dozens of meters wide, with quite a few academy wizards passing by on either side.
Their attire was different as well. It seemed that the darker green a Witch Robe was, the higher its wearer's status and strength.
Ian had originally wanted to ask a few questions.
But the wizard ahead kept a cold expression throughout, so Ian did not ask. He merely observed in silence.
A far larger Teaching Area, dedicated experimental zones, and an even larger Library—
Especially the latter, which covered several acres and stood five or six stories high.
Ian was deeply envious.
Before long, the two arrived at the most central area of Green Corridor Wizard Academy.
A lake like emerald jade lay before them, with an island at its center. The elemental concentration here had already reached more than five times that of a normal environment.
"Emerald Lake. The teacher is on the island in the center of the lake. Come with me."
At that point, the wizard leading the way turned around and spoke.
Ian nodded.
The two came to the lakeside and boarded a small boat.
They soon arrived on the island.
Though it was called an island, it was by no means small. Ian estimated that it covered at least several dozen acres.
Before long, Ian arrived before a pitch-black Wizard Tower.
"Teacher, I've brought him."
The green-robed wizard spoke softly toward the inside of the Wizard Tower.
The doors slowly opened.
