Currently, Merlin's Mind Heart was at least half its size than before. Despite that, the Mind Heart was able to accumulate more Mind Power – at least double its volume from before.

Such a humongous Mind Power would allow Merlin's Seventh-level Mind Heart to possess Mind Powers equivalent to an ordinary Ninth-level Spell Caster.

The average Mind Power Masters already possessed extremely potent Mind Power that far surpassed the ordinary Spell Casters but Merlin's Mind Power was even greater than the powerful Mind Power Masters. Merlin had compressed the Mind Heart almost to its limit. Back then, even Wizard Ossais did not compress it to the limit.

In some sense, Merlin's embarkation was much better than Wizard Ossais, so he should be able to cultivate Nine Hit Strike more smoothly compared to Wizard Ossais.

In reality, that was also true. While Merlin continuously cultivated Explosion Theory and compressed the Mind Heart, he would also cultivate Nine Hit Strike. The first three strikes of Nine Hit Strike were relatively easy.

Although a large amount of Mind Power was still quintessential, Merlin's Mind Power was already sufficient. Therefore, when Merlin began to cultivate Nine Hit Strike, he was quickly able to cultivate the first three strikes successfully.

"Let's try it out!"

Once Merlin had finally compressed the Mind Heart to the limit, he surreptitiously wielded Nine Hit Strike. An invisible Mind Power slammed heavily onto a large boulder outside the house.

"Bang!"

A dull slam resounded. Mind Power was shapeless and invisible but upon breaking through to the Seventh-level, it had undergone a qualitative transformation. The invisible Mind Power would turn from intangible to tangible, and was able to interact with visible objects. It was not only remarkable but also incapable of resistance.

Upon the first strike, the large bounder only tremored slightly, seemingly impacted by a strong attack. This boulder was one of the toughest rocks, so even a Seventh-level spell would not be able to affect it.

Since the boulder was difficult to break apart and had no use in alchemy, it was simply relegated as decoration. Right now, however, it could be used to assess the strength of Merlin's Nine Hit Strike.

The first strike was unfruitful, so Merlin continued wielding Nine Hit Strike.

"Boom!"

Another dull thud resonated. The large boulder appeared to be impacted by an invisible multi-directional attacking force. It quaked steadily but did not seem close to shattering yet.

"Three Hit Strike!"

An invisible fluctuation appeared on Merlin's body. This fluctuation was invisible to the naked eye but Merlin could feel it clearly. A fearsome quiver – like ripples in the water – slammed violently onto the large boulder.

"Crack."

This time, the large boulder was not spared. A powerful multi-directional force smashed into the large boulder and pummeled it into dust.

Seeing the previously rock-solid boulder had turned into a pile of dust shocked even Merlin. The attack of an Occult Mind Spell was unique that it was sneaky, shapeless, invisible, and incapable of resistance. It was completely different compared to Spell Casters' spell attack.

Especially Nine Hit Strike with each subsequent strike stronger than the last. Merlin's Three Hit Strike was already comparable to the power of a peak Eighth-level spell, so very few Eighth-level Wizards would be able to withstand it.

The power of his spell even exceeded Wizard Ossais' Three Hit Strike.

The uniqueness of an Occult Mind Spell like Nine Hit Strike laid in the fact that no matter who cast it or how powerful the Mind Power was, the same Three Hit Strike would possess almost the same strength.

However, for now, Merlin could only cultivate up to Three Hit Strike. His Mind Power was still not enough for him to cultivate Four Hit Strike. Generally, his Mind Heart would need to transform to an Eighth-level Mind Heart to be able to cultivate it.

Nevertheless, Merlin's Mind Heart was very special because it had undergone continuous compression under another top Occult Mind Spell, Explosion Theory. Coupled with the fact that Merlin's original Mind Heart had been greatly compressed, his Mind Heart had practically reached the utmost limit of compression.

Therefore, perhaps when Merlin once again accumulated enough Mind Power to fill out the limit of the Seventh-level Mind Heart, he might be able to cultivate Four Hit Strike.

"Fuh…"

Merlin exhaled lengthily. He could feel that he had not left this room for a few months but the outcome had been fruitful, so Merlin was very satisfied.

"It's time to go out!" Merlin stood up and flew toward Wizard Yatho's palace.

…

In the palace, in the midst of Wizard Yatho and Wizard Mogan exchanging discoveries about their Maxim consolidation, Wizard Yatho suddenly paused. Then, he smiled at Wizard Mogan. "Merlin is coming here. It looks like he has achieved quite a bit!"

Just as he finished speaking, the door of the palace was slowly pushed open. Merlin's face was beaming as he paid his respects to Wizard Yatho and Wizard Mogan.

Wizard Mogan's gaze fixed on Merlin for a long time, and a trace of astonishment appeared in his eyes. It appeared that Wizard Mogan had detected some clues but he did not inquire further about the Occult Mind Spells. From Wizard Mogan's perspective, regardless of how astounding Occult Mind Spells were, they were useless if it was impossible for the Spell Caster to become a Great Legend.

In Wizard Mogan's eyes, Merlin was already earmarked for success. He was a talented Wizard who had the potential to become a Great Legend in the future. Hence, Merlin's efforts should be devoted to becoming a Great Wizard.

"Wizard Yatho, I wonder where's Wizard Ossais? I would like to express my gratitude to him in person."

Merlin was ready to leave the Yatho Dimension. The purpose that he came to the Yatho Dimension for had been achieved, so naturally, he wanted to thank Ossais for the Occult Mind Spells.

However, Wizard Yatho shook his head dejectedly. "Wizard Merlin, I'm afraid your wish cannot be fulfilled. About more than a month ago, Wizard Ossais had left the Yatho Dimension to traverse the Void Zone. He wants to break through the shackles and perfect the Mind Power Masters' system as well as become a Legend…"

As he spoke, Wizard Yatho appeared rather gloomy. Of course, he was unwilling to let Wizard Ossais leave because he was one of the strongest Great Wizards in the Yatho Dimension. With Wizard Ossais guarding the fort in the Yatho Dimension, Wizard Yatho felt a lot more at ease.

Moreover, Ossais' departure this time was obviously quite sorrowful. Even if Ossais did not manage to break through, he probably would not come back to the Yatho Dimension again.

"Wizard Ossais has left?"

Inside Merlin's mind, Wizard Ossais' hopeful expression beckoned. Merlin knew that Ossais had spent his entire life perfecting the system of Mind Power Masters, but until now, he had not been able to achieve substantial progress.

His only achievement was inventing Explosion Theory and Nine Hit Strike. Additionally, Ossais himself was only able to cultivate up to Seven Hit Strike. If he could surpass Seven Hit Strike and reach Eight Hit Strike or Nine Hit Strike, then, he might be able to rival a real Legend and fulfill his lifelong dream.

So, Ossais' departure this time was probably his final desperate attempt, hoping that somehow in the vast, endless Void Zone and the hundreds and thousands of dimensions, there would be an opportunity for him to cultivate Eight Hit Strike or Nine Hit Strike.

Therefore, without achieving the desired outcome, Ossais would not come back.

"It's truly regretful!"

Merlin shook his head and shifted his gaze to Wizard Mogan. At this point of time, Wizard Mogan should be bidding their farewell to Wizard Yatho.

However, for a moment, Wizard Mogan did not speak. Instead, he murmured in a low voice, "Merlin, I'm preparing to recommend you to Arcane City!"

"Arcane City?" A look of confusion flashed across Merlin's face. He had never heard about it before. So, in a low voice, he asked, "Teacher Mogan, what's Arcane City?"

Wizard Mogan did not reply but Wizard Yatho rumbled in laughter. "Haha, Merlin, you're so lucky. In order to send you to Arcane City, Wizard Mogan has to use up his one and only recommendation quota!"

"Only one recommendation! For Merlin to enter Arcane City, I believe this recommendation will be immensely helpful!"

Wizard Mogan took another look at Merlin and said, "Merlin, Arcane City is a dimension created by three Ultimate Arcane Wizards. Within the vast Void Zone, there are a total of three Arcane Cities. All of them were created by three Ultimate Arcane Wizards. Inside Arcane City, there's everything that a Spell Caster might need. The dimension was created by the Great Arcane Wizards to nurture the cream of the crop among Spell Casters! A prodigy like you is hard to come by, even in the hundreds and thousands of dimensions. If you don't enter Arcane City now, I don't know how many more detours you'll have to take."

Upon hearing this, Merlin was staggered to the core of his heart.

Information such as the three Ultimate Arcane Wizards who had created a dimension, and so on, constituted secrets that were known only to the Great Legends or those extremely close to them. Otherwise, only the most powerful Great Wizards in the endless dimensions would know of these secrets.

The words "created a dimension" also caused a huge shockwave in Merlin's heart. Even an Honored Legend could not possibly create something as large as a dimension. Perhaps creating a more perfect subspace was possible but creating a dimension was beyond the understanding of even the Great Legendary Wizards.

Only the Ultimate Arcane Wizards would possess such colossal power that was able to create a dimension. It was not surprising that the Arcane Wizards were honored with the title "Ultimate".

It represented a true apex that could not be topped!

Merlin understood very well the advantages of this Arcane City. Probably, within the vast Void Zone and hundreds and thousands of dimensions, this was the place where the true top prodigies gathered.

This dimension was specially created by the Ultimate Arcane Wizards, and was best suited for Spell Casters. It contained the most abundant resources in the Spell Caster world as well as the most sophisticated knowledge of spells, runology, alchemy, potions, and so on. If Merlin was to enter inside, he would definitely improve by leaps and bounds.

Furthermore, he would be able to congregate with Spell Casters who were far more talented than Asher. Merlin could not imagine how impressive the situation would be.

It had been a long time since Merlin was excited about anything, but now, after learning about Arcane City and that Wizard Mogan intended to use his only recommendation to send him into Arcane City, Merlin's mood was inexplicably ecstatic.

This was an opportunity not to be missed!
