After analyzing Mindscape Transportation again, Leon confirmed a few more things. It took him quite a while, but he managed to use Mind Control and make a fire dragon attack the boundaries of the mindscape. At first, he thought that place was somewhat similar to an illusionary trap. Whenever he tried to fly in a straight line, toward one direction, he would always return to the island, but that wasn't true. He would always return to the island because not even Sekundez could create a real-size world. Perhaps the original spirit could, but not her fragment.

Leon felt his mana decreasing a little faster when the fire dragon started to use its spells toward all directions. Although there was nothing to attack, that space had been created by mana, so the mana he was using to keep that space existing was being damaged.

"So, I have to attack this very dimension and make her run out of mana..." Leon concluded. "This will be hard... even if Sekundez lied at some point. She is still powerful enough to create millions of monsters and billions of zombies using her powers in this imaginary dimension. Most likely, she didn't create them all at once, but still... to create those dragons and even make them steadily grow strong. She had to use a lot of mana."

Leon still didn't know the limits of Mindscape Transportation, but he was pretty sure Sekundez's skill was already at the max level. Maybe that dimension could only have that size, but there was also a possibility that Sekundez just created with that size to save mana. She got attacked once, so it wouldn't be weird if Sekundez got attacked again. Knowing that anyone smart enough wouldn't spend all its power in a trial.

"I got a lot stronger in those four hundred years, but I still can't imagine myself being strong enough to destroy the spell of someone who created such a perfect barrier around its temple," Leon rubbed his chin when he recalled those months where he had been forced to starve to death several times.

Maybe Leon could find a way to destroy that dimension using brute force. He was only good at that, after all, so why not? However, he gave up on that idea. Destroying the dimension seemed like a good idea, but then he recalled the Spell-Breaker... a skill that he learned to counter magic spells. The problem was that skill only worked when the enemy was about to use their skill. Leon couldn't use to destroy a spell that was already active.

"Mmm... there is a more powerful version of Spell-Breaker," Leon said. "Usually, to counter a spell, I would have to use the same amount of mana, but in this situation, I just have to disturb the mana that is being used to maintain this dimension."

Although the logic behind it was simple, Leon had no idea how to apply it. Besides, considering the fact that Leon could use Mana Magnetism and recover a lot of mana from a space that couldn't create any mana, perhaps the reactions of the ambient were just an illusion created by a simulation-like ambient... Leon felt a terrible headache by thinking about it since he wasn't a theoretical person.

There was also a chance that Leon was just worrying too much about something very unlikely, but it was better to be safe than sorry. In the worst-case scenario, he would be forced to give up on Sekundez's power, but his mental health was more important than that.

"As I suspected... there isn't a skill like Spell-Breaker Ilyana's vault," Leon massaged his eyebrows.

After a few more tests, Leon confirmed that only mana and its effects would be able to damage that dimension. Although his main goal was to cancel the spell, he had to prepare himself for the possibility that he may not learn that. If the worst comes to the worst... Leon would have to use brute strength.

Instead of learning new spells, Leon used the extra mana he was gaining to expand the scope of his Mana Barrier to its limit since there was a chance that defensive spells would counter the effects of that dimension. However, as expected, expanding the scope of that skill beyond the limits of its level wasn't easy, and a lot of mana had been used... just to cover the entire island, Leon had to expend enough mana that equaled to the dragons entire mana pool... Leon had to consume four kilograms of mithril that he had thought it would be enough in just a minute.

Congratulations! The skill Mana Barrier has leveled up.

"By my calculations... I will have to spend ten times more mana to make a Mana Barrier reaches the boundaries of this dimension," Leon bit his nails. "If that fails, I will have to try Mind Armor and Reflect Armor, and those will consume a lot more mana... shit."

The chances of Reflect Armor to work in that kind of situation were quite dim, but in case Mind Armor fails, Leon had no idea what to do next. However, before Leon could try any of those, he had another idea. It was a bit risky since he never tried anything like that before, and he was pretty sure that kind of magic wasn't supposed to be used like that... but maybe Spatial Manipulation could help Leon with that.

"Although the cost of that skill is already stupidly high considering what it can do, maybe if I increase the output of the spell... I will be able to change the dimensions of this place," Leon nodded to himself. "There is a chance that something may go wrong along the way, but I won't die... probably.'
