After pondering for a while, the three spellcasters had already taken the lead in stepping into the third layer, Merlin took a deep breath, and finally did not hesitate any longer, this is a free opportunity to enter the Spirit Tower, it is not easy to come by, naturally you can't give up halfway.

"Whoosh".

As a result, Merlin also stepped into the third layer in an instant.

On the third floor, there are huge mirrors on all sides, and from the mirrors, you can see the surroundings of Merlin, which is very clear. The three casters also looked around in amazement, and there were large, smooth mirrors everywhere, even under their feet and on the top of their heads.

The third floor of the spiritual tower is clearly a room surrounded by mirrors.

Merlin frowned, not knowing what the mystery of the third layer was, so he simply sat on the ground and waited quietly.

I don't know how long I waited, Merlin felt a little tired, and then slowly fell into a deep sleep, which was without warning, and it seemed that even Merlin didn't notice it.

In his sleep, Merlin seemed to have returned to the Kingdom of Light, back to Blackwater City, when Blackwater City was controlled by the Church of Light, Merlin and his father Wilson Sr. rebelled, and finally saved the Wilson family.

But in his sleep, everything seemed to be the same, but things were developing completely differently, Merlin was one step late, the Wilson Castle had been burned to ashes, and Mei Xue and most of the Wilson family also died miserably in the Wilson Castle.

Merlin was remorseful, and later, he even saw his father, Wilson Sr., fall before his eyes, and he was powerless to recover and save the entire Wilson family.

The dream was all too real. It tugged at Merlin's heart. An indescribable feeling of sadness. Filled Merlin's heart, and before he knew it, Merlin had shed two lines of tears.

"No, it's all unreal! It's fake, I changed the Wilson family!"

Merlin's heart sank, and before he knew it, he had fallen into a fantasy world, ever since he had a heart of darkness. Coupled with strong mental power, it is difficult to fall into the illusion.

But now, he unconsciously fell into a fantasy, and there was no trace of discomfort, in the dream, everything seemed to be real.

Merlin looked at "himself" in the mirror, and there were still tears on his face, this was the first time Merlin had seen himself "cry".

"Everything in a dream is a different result......"

Merlin carefully recalled everything in the dream, and it was strange to say. Everything in the thro, even the details. Merlin remembers it very clearly, and when he recalls it now, he will feel a trace of sadness.

Suddenly, Merlin checked his mental power, and actually increased a little, and a possibility came to his mind.

"Could it be that the third layer of the spiritual tower is actually to stimulate spiritual power with 'sadness', so as to increase spiritual power?"

Ordinary people's joy and sorrow will lead to great ups and downs in the spirit, but that is only for ordinary people, even if they become a spellcaster, this kind of joy and sorrow will increase their spiritual power, but it is really minimal.

Unexpectedly, these most basic things have been magnified countless times in the spiritual tower, and naturally, there are many spiritual powers that have been increased.

Merlin looked at the three spellcasters again, none of them had yet woken up, and their faces had already shown extremely sad looks, they must have fallen into grief in a dream, in this case, after they woke up, their mental strength would definitely increase greatly.

Merlin lowered his head, thoughtfully, he had roughly understood the role of the spiritual tower, it was indeed very magical, at the beginning it was the most direct pain stimulation, and then the emotional stimulation, although it was the most basic way to stimulate mental power, but in the spiritual tower, this stimulation was infinitely amplified, natural, and the effect was much better.

Like Merlin, the mental power and willpower are too strong, which is not conducive to improving the spiritual power in the spirit tower, and in the spirit tower, you must completely immerse yourself in the illusion and feel the unparalleled sadness in order to improve the spiritual power.

Merlin took a deep breath, the sadness in his sleep, he still had a faint ache when he thought about it now, he really didn't want to face that sadness again.

However, in order to improve his mental power, Merlin could only choose to fully integrate into his sleep, so he gently closed his eyes, completely immersed in sleep, feeling the heavy sadness, and his mental power began to improve slowly and steadily......

Level 3, 4, 5......

Merlin rose slowly and steadily all the way, and the three spellcasters who had broken into the Spirit Tower with Merlin before had already reached the seventh layer, but they couldn't hold on to it on the seventh floor, and left the Spirit Tower after the last moment.

Merlin, on the other hand, was a little slower, he was always in every floor, completely immersed in his sleep, without the slightest thought of resistance, and let the spirit tower control his dreams.

In the dream, Merlin experienced all kinds of joys and sorrows, and they were very real, all of which were things that Merlin had experienced before, and only in this way could Merlin empathize.

Of course, there are many benefits to this, and the most direct benefit is Merlin's spiritual power, which is rising in a straight line until it reaches the eighth layer.

The eighth floor was where the fat mage Arrot arrived, Merlin looked around curiously, it seemed that it was a very simple room, and there was nothing unique about it.

"I don't know what kind of dream Lu Dao had this time?"

Merlin was faintly looking forward to the dream, he broke through the spirit tower once, and the speed of spiritual power increase was very fast, almost to the limit, and after breaking through a few more layers, it was estimated that he would be able to truly reach the limit of the seventh-level spiritual heart.

This growth rate is faster than Merlin taking potions, of course, it is still not as fast as divinity, but divinity is a treasure that even legendary mages need, it is very rare, unless it is a life to suppress the gods, it is difficult to get divinity.

Moreover, even if the gods are suppressed, if they do not have overwhelming strength, the gods can rely on the power of divinity to deal with the great legend, and they will not be easily obtained by the caster.

Therefore, in addition to divinity, this spiritual tower is indeed of great benefit to the tempering of spiritual power.

"Boom".

Suddenly, while Merlin was still waiting to enter the dream, he felt a shock in his mind, as if a big explosion had occurred, and then Merlin felt as if his spiritual power had been drained by countless tentacles.

This feeling was really uncomfortable, even Merlin couldn't help but gasp, and kept inhaling carefully, trying to alleviate the pain, but this pain became stronger and stronger, almost making Merlin unbearable.

What's even more frustrating is that Merlin can't detect what this mysterious power that drains his spiritual power is, just like the previous seven-story spiritual tower pulling him into a dream.

"No wonder Arrot couldn't bear it, so he had to break through to the eighth layer. ”

Merlin couldn't help but smile bitterly, this kind of direct draining of mental power was too painful, and he lost his mental power in an instant, and Merlin's whole person became extremely weak.

Mental power is also the key to the caster, even if Merlin used mental power excessively before, it has never been like now, and spiritual power has been completely drained.

The consequences of being drained of mental power are obvious, Merlin is now unable to cast a spiritual arc, and cannot use mental power to stimulate the spell model and thus release the spell.

In short, the current Merlin and Sora have many powerful means, but they can't use them.

Once the spiritual power is gone, the consequences are quite terrible, and now Merlin has some lingering palpitations, and he can't care about much, so he starts to meditate, although the speed is very slow, but he can recover some spiritual power.

Sure enough, as time passed, Merlin's spiritual power gradually recovered, but as soon as he recovered, that mysterious power once again drained Merlin's spiritual power.

Again and again, over and over again, Merlin stayed in the eighth-layer spirit tower for almost three days, and every time his spiritual power was drained, when his spiritual power recovered, Merlin's spiritual power would increase a lot.

Now Merlin's spiritual power is almost at its limit, just a little bit.

"Boom".

When Merlin's mental power was drained again, he could even clearly feel that there was a very full feeling, yes, a very full feeling, and his spirit was slowly recovering, like a dry river, a small stream began to appear, and it would soon turn into a raging monstrous river.

Finally, when Merlin's spiritual power was restored again, his spiritual power had reached its limit, and Merlin could feel that no matter what, as long as his spiritual heart was still level seven, then it would be impossible for him to increase his spiritual power.

The eighth layer had no effect on Merlin, and Merlin did not hesitate at all, and went directly to the ninth layer!

On the ninth floor, Merlin closed his eyes slightly, quietly experiencing the fullness in his spiritual heart, this time, his spiritual power gradually radiated, and there was an invisible fluctuation.

"Quadruple Strike!"

Merlin opened his eyes suddenly, this was a natural feeling, Merlin's attack-type spirit secret technique, after the spiritual power reached the limit of the seventh-level spiritual heart, he could finally cast a quadruple blow.

Once the Spiritual Secret Technique reaches the Quadruple Blow, then Merlin has one more means that can rival the ninth-level spellcaster, which is the only powerful means that can rival the ninth-level caster after the fusion spell.

As for the rest of the Ice Country, Perfection-level spells, fusing magic energy, and even the fourth form of the Eye of Darkness, they could only reach the peak of the eighth level, which was not comparable to the ninth-level spellcaster, and was not a great threat to the ninth-level caster.

"Spirit Tower, what a great place!"

Merlin was a little reluctant to leave the Spirit Tower, this place was simply an excellent place to cultivate spiritual power.

"I don't know what kind of way the ninth layer of the Dao Spirit Tower will sharpen its spiritual power?"

Merlin began to pay attention to the ninth layer, so far, he didn't seem to notice anything special about the ninth layer, but out of caution about the spirit tower, Merlin was still very cautious and didn't dare to relax in the slightest. (To be continued......)
