Merlin had arrived at the accommodation arranged by Wizard Yatho, and began to calm down. What happened to the black cat Didimoss was quite mind-blowing to him. Even now, he found it hard to believe.

However, words spoken by Wizard Yatho and Wizard Mogan would not be untrue. Once the black cat Didimoss woke up and changed its form into a living being, he would likely possess powers comparable to a Legend.

Nevertheless, no one knew how long it would take for the black cat Didimoss to wake up.

Then, Merlin thought about the Matrix. The Matrix was full of mysteries, and to date, Merlin was still uncertain about how the Matrix was able to derive new spells using the power of Maxims.

Previously, when the Sky God appeared, the Sky God tried to use boundless divine energy to kill Merlin with a single hit. However, the divine power was instead absorbed and stored by the Matrix.

"The Matrix, activate!"

Merlin activated the Matrix and began to examine it carefully. On the surface, there seemed to be no change, and it could still derive new spells.

The only change was that there was some energy stored inside the Matrix. This energy was converted from absorbing the Sky God's divine energy. However, the amount of divine energy was too little, so the converted energy was approximately enough for one or two new Sixth-level spells only.

Merlin did not use this energy immediately. He was currently a Fifth-level Spell Caster and did not have to exert a lot of Mind Power to balance his Spell Models. Therefore, Merlin's Mind Power was at its highest threshold. Since Merlin had not yet learned Occult Mind Spells, he did not know what kind of Mind Power requirements there would be. As such, he temporarily set aside the plan to derive new Sixth-level spells.

At least, he would wait until he had cultivated Occult Mind Spells.

"In a sense, Occult Mind Spells seem to be a lot more powerful than spells of the same level. It's not surprising that it's considered to be in a class of its own. If not for the fact that Mind Power Masters are unable to produce a powerful enough existence to rival the Great Legends, the Mind Power Masters might be on par with the Spell Caster system!"

Previously, from the bodies of Damsy and the others, Merlin had witnessed the power of Occult Mind Spells. Thus, his desire to possess Occult Mind Spells burned even greater than before.

So, after a short rest, Merlin got up and flew toward Wizard Ossais' residence.

The Yatho Dimension was very vast. Although Ossais was one of the most efficient subordinates under Wizard Yatho, he also enjoyed a unique and high status. He was a powerful Wizard who was second only to Wizard Yatho in this dimension. Therefore, Ossais did not live in Wizard Yatho's palace but in his own residence.

When Merlin arrived at Ossais' residence, he discovered that it was also a palace. The luxurious palace appeared to be largely comparable to Wizard Yatho's palace. There were numerous servants coming and going, and among them were also some Great Wizards.

The Great Wizards would not be Ossais' servants but his followers. Even so, this spoke volumes about Wizard Ossais' influence. Someone who had Great Wizards among his followers was definitely the top Great Wizard.

"Swish."

Merlin landed, and was immediately barred by a few Spell Casters from the palace. When Merlin had revealed his identity, these few Spell Casters went inside to seek instructions. Finally, they respectfully led Merlin into the palace.

In the luxurious palace, Merlin entered a secret chamber. Ossais was sitting quietly inside the secret chamber, his expression revealed a sea of calmness. Although Merlin had arrived, he did not open his eyes.

"Wizard Ossais!"

Merlin greeted him with respect. Merlin did not behave arrogantly simply because he was the Great Legend Wizard Mogan's disciple. On the contrary, he was very respectful toward Wizard Ossais.

"Swoosh."

Wizard Ossais opened his eyes. His eyes flashed with a stern gaze as he stared at Merlin and assessed him. After a long moment, Wizard Ossais gently shook his head and sighed softly. "Wizard Merlin, you're are the Great Legend Wizard Mogan's disciple as well as a prodigy among Spell Casters. You have a high chance of becoming a Great Wizard and even a Great Legend! Why do you bother to learn Occult Mind Spells? You must know that among the Mind Power Masters, no one can compare to the Great Legends."

Ossais was also aware of Merlin's background. Not only was he Wizard Mogan's disciple but he was also highly valued by Wizard Mogan. Hence, his future achievements would be unimaginable. Even if Merlin ended up becoming a Great Legend one day, Wizard Ossais would not be surprised.

However, for such a talented person like Merlin to devote his time and energy on Occult Mind Spells, it seemed almost like discarding his roots.

Spell Casters who learned Occult Mind Spells and became Mind Power Masters typically constituted those who had given up hope to advance further as a Spell Caster. For a talented Spell Caster like Merlin to take the initiative to learn Occult Mind Spells was extremely rare.

Merlin smiled. The purpose of him studying Occult Mind Spells was very simple. It was to become more powerful! Possessing a unique skill was equivalent to having an additional power, and Occult Mind Spells was a unique power which was completely different from spells. They belonged to a class of their own and were truly remarkable. Naturally, Merlin wanted to learn them.

Moreover, for most other Spell Casters, they needed to consume most of their time and energy on their Spell Models. Merlin, on the other hand, found it incredibly simple. Thus, he had a lot of time and energy to cultivate Occult Mind Spells.

"I want to become more powerful!"

Merlin only uttered this sentence and did not elaborate. He believed that Ossais would be able to understand what he meant.

Wizard Ossais stewed for a moment and nodded subtly. "You want to become more powerful? Not bad, you're right. Occult Mind Spells aren't inferior to spells. In fact, to some extent, they're even more powerful! Your Mind Power shouldn't be too weak or you wouldn't have thought about cultivating Occult Mind Spells. Some of the top Mind Power Masters and I have been pursuing a substantive advancement in the field of Occult Mind Spells that would break through the bottleneck and allow Mind Power Masters to be on par with the Great Legends. This would make Mind Power Masters truly an independent system from the spells!"

This was Ossais' greatest dream. For this reason, he had devoted so much effort to create top-of-the-line Occult Mind Spells, but until now, he had not succeeded.

Advancing from Great Wizard to Legend was also a qualitative transformation that was highly challenging. There were so many Great Wizards in these endless dimensions that it was almost impossible to count them.

Great Legends, on the other hand, were very rare. Every time a Great Legend was born, it would shake the entire Spell Caster civilization. Even the Great Arcane Wizards would inform all the Spell Casters.

Legends were basically the Spell Casters' core strength. The fact that the Spell Caster civilization had been able to develop to such a prosperous extent was largely contributed by the Legendary Wizards acting as the core strength. At the very least, in any new dimension, as long as the elements existed, then a god would be born.

Only the Maxims consolidated by the Legendary Wizards were able to oppose the gods and conquer the dimension!

The Spell Caster civilization had been very well-developed, but the appearance of Mind Power Masters had not been too long ago. In fact, it was only after the Spell Casters began to leave the Glorious Land and headed into the hundreds and thousands of dimensions that the Mind Power Masters came into existence.

As soon as the Mind Power Masters emerged, their development was extremely fast. They managed to create top Occult Mind Spells, and the topmost Mind Power Master was infinitely close to the Great Legends!

However, it was very difficult to develop an independent and perfect system. Moreover, for this purpose, it was critical for them to produce a powerful Mind Power Master on par with the Great Legends.

Only when a powerful master who could rival a Great Legend was born, then would the Mind Power Masters be recognized as a perfect and independent system apart of the Spell Casters.

"Wizard Merlin, regardless of your motivation to cultivate Occult Mind Spells, I hope that you can devote some energy toward Occult Mind Spells in the future. At least, you must break through the bottleneck and perfect the system of Mind Power Masters to become a powerful Mind Power Master who could rival the Great Legends!"

Ossais' only wish was to be able to see the birth of a Great Legend – an equivalent among the Mind Power Masters.

Looking at Ossais' expectant gaze, Merlin nodded faintly. However, he knew in his heart that perfecting the Mind Power Masters' system was simply too difficult.

Perhaps, the Mind Power Masters' system was fundamentally unable to produce an existence on par with the Great Legends. Perhaps, having a peak Great Wizard's powers was the highest possible limit of the Mind Power Masters' system.

After Wizard Ossais had finished speaking, he took a deep breath and his expression turned solemn. With a dignified tone, he said, "Wizard Merlin, since you've passed my test, then I will not hold back and teach you my top Mind Occult Spells! However, you must first let me know, how big is your Mind Power?"

Since Ossais would be teaching Occult Mind Spells to Merlin, understanding Merlin's Mind Power or the true situation of his Mind Heart was essential.

Merlin nodded and immediately activated his Mind Heart.

"Whiz."

Merlin's Mind Power changed from intangible to tangible, and transformed into a large fist that violently thumped toward Ossais. Its sight and sound were magnificent, just like releasing a powerful spell.

This was the most direct and rudimentary use of Mind Power though its force was commendable. This time, Merlin did not hide anything and mobilized almost all his Mind Power, so the resulting impact was huge.

Sensing such a sizable Mind Power, Ossais squinted and his heart filled with astonishment.

Currently, Merlin's Mind Power had far exceeded an average Eight-level Spell Caster's Mind Power, almost reaching an average Ninth-level Spell Caster.

Merlin only had a Seventh-level Mind Heart!

"Haha, not bad, your Mind Power is very powerful and have fulfilled the requirement to cultivate Occult Mind Spells! Merlin, has your Mind Heart achieved the limit of Seventh-level Mind Heart?"

"Limit? There's still a little way to go but it should almost be there. Soon, I'll try to break through to the Eighth-level Mind Heart!"

The Mind Power that Merlin had accumulated was already sufficient enough. Merlin could also sense that he could no longer continue to compress the Mind Heart. Very soon, it would reach its limit.

Therefore, Merlin also began to prepare to break through to the Eighth-level Mind Heart!

"Not yet at the limit?"

Ossais' eyes glinted, and a notch of excitement appeared in his tone.

"Merlin, I'm afraid you don't have to rush to break through to the Eight-level Mind Heart, you still have to accumulate more Mind Power! As for compressing the Mind Heart, just trust in my Occult Mind Spells, you'll be satisfied!"

Ossais smiled faintly, and a mysterious expression appeared on his face.
