Mirror Dimension is an extraordinarily powerful Magic.
Within Mirror Dimension, it is as if you possess an entire world, becoming a god.
Inside his Mirror Dimension, Zhao Yu continually explored its formidable capabilities.
He could not only alter objects within it but also use the space itself as a weapon—pinning foes beneath crushing debris or designing lethal traps.
Of course, such precise manipulations normally consume vast amounts of mental energy, far more than merely reshaping space.
The more intricate the change, the greater the psychic cost.
Thus, Kamar-Taj Sorcerers find using Mirror Dimension taxing.
No one attempts complex spatial transformations—not even a Supreme Sorcerer.
But Zhao Yu was different.
His Mirror Dimension operated on its own, requiring no mental effort to sustain, leaving his mind free to command the space.
Watching his realm obey his will brought a smile to Zhao Yu's face.
With Mirror Dimension mastered, his combat power had leapt several tiers.
Against an enemy like Hulk, he could simply banish him into Mirror Dimension—Hulk, formidable as he was, could never escape.
"Ding!"
"Your extraordinary insight into space grants your Mirror Dimension a cultivation bonus."
"Ding!"
"Your Mirror Dimension has reached Level 2."
Zhao Yu beamed. Mirror Dimension was now the fastest-advancing Magic in his arsenal. Every bonus and accolade had propelled it to Level 2 in record time.
But his joy was short-lived.
"Ding!"
"Your Mirror Dimension has reached Level 2, matching your Portal's level."
"Due to their shared nature, your Mirror Dimension has challenged your Portal."
"Ding!"
"Your Portal challenge has failed and willingly merged into your Mirror Dimension."
"Your Mirror Dimension has undergone a fusion mutation."
"Ding!"
"Your Mirror Dimension has become Multi-Layer Mirror Dimension."
"Your Multi-Layer Mirror Dimension, inheriting the strength of two Magics, has been upgraded to Level 3."
"Ding!"
"Your Multi-Layer Mirror Dimension is elated and its cultivation speed has greatly increased."
A cascade of system messages left Zhao Yu dizzy.
Reading the log carefully, he felt bewildered.
Magic could fuse and mutate on its own? He had never heard of such a thing.
He did not know if Kamar-Taj had any record of this—but he doubted it.
He summoned his Multi-Layer Mirror Dimension and examined the system's data, astonishment on his face.
This fusion mutation was astonishing. The Multi-Layer Mirror Dimension not only inherited both Magics' traits but had grown more powerful.
Now, even within another Sorcerer's Mirror Dimension, he could deploy his own.
If his mental strength exceeded theirs, he could seize control.
If he were weaker, he could at least negate their advantage.
It was unbelievable—surely not even a Supreme Sorcerer could achieve this.
At most, others could open a Portal to escape from someone else's Mirror Dimension—like Casillas, a master of that space.
Casillas could slip out of a Supreme Sorcerer's Mirror Dimension, but he could never turn the tables as Zhao Yu now could.
Moreover, Zhao Yu's Portal itself had changed.
He extended his hand and a gilded Portal shimmered into being—its edges blurred like fractured bubbles, translucent crystals dancing in the golden light, making it dazzlingly beautiful.
These were stray energies from his Mirror Dimension.
And his Portal now linked directly to his Mirror Dimension: anyone passing through without his permission would enter his realm instead.
This Multi-Layer Mirror Dimension was far stronger and more versatile than its predecessor.
"How remarkable the system is—Magic can fuse like this," Zhao Yu murmured.
"This is practically the creation of new Magic."
He shook his head in wonder at the system's power: not only auto-cultivating his spells but merging them into novel forms.
"But what triggers this fusion mutation?"
Zhao Yu stroked his chin.
If Portal and Mirror Dimension shared a common origin, then other related Magics—Magic Shield and Ring of Raggadorr—should fuse as well.
Yet they had not.
"Could it be that they must be at the same level?"
He pondered. Magic Shield was the first spell he learned and trained tirelessly.
Its rank now dwarfed all others, an astonishing Level 6—outstripping even many veteran Sorcerers and several Grand Sorcerers.
Other spells hovered around Level 3 or 4.
"It seems level parity is a key factor," Zhao Yu concluded.
"I'll have to test that when I can."
He had tasted victory. After fusion, his Magics not only retained their functions but grew more powerful and varied.
Imagining a future where his entire arsenal underwent similar mutations—foes fleeing in terror—Zhao Yu grinned broadly.
"I must train even harder," he resolved.
"The more Magics I master, the more fusion possibilities I'll have."
Kamar-Taj was hailed as a sanctum of Magic.
The Supreme Sorcerer gathered spells from around the world and, being a remarkable Sorcerer herself, created many.
Thus Magic was everywhere in Kamar-Taj.
By remaining there, he would learn every conceivable spell—and if they could fuse, he would hold formidable trump cards.
With that thought, he eagerly anticipated tomorrow's lessons, rubbed his chin, and resumed his cultivation—leaving his Magics no moment's rest.
