"Click".

The marrow of extreme cold penetrated deep into the bone marrow, almost freezing Merlin's whole body, and layers of ice crystals quickly appeared on Merlin's body surface, but Merlin didn't care at all, instead staring at the mysterious symbol carved on his arm, which was the key to cultivating the ice of bondage.

"Buzz".

The symbol of the Ice of Bondage gradually emitted a faint shade of blue, and then submerged into the skin on the arm, forming a shallow imprint.

The Ice of Bondage has been successfully cultivated!

However, Merlin did not relax, the ice of binding fused with magic energy, and completely integrated into the ice spell, at the same time, Yu Lin felt that between the wind spell and the ice of bondage, there was a faint sign of wanting to fuse.

Merlin was overjoyed in his heart, and sure enough, this phenomenon appeared again, the same feeling as when he fused with the fire spell after he cultivated Thunder Fury before, he wanted to fuse.

This time, though, Merlin was much more cautious, gradually unleashing the wind element, observing the changes between the wind spells and the ice spells.

Gradually, the wind spell and the ice spell fused together, the wind spell is a speed type, the speed is extremely fast, and where the spell passes, there is the effect of ice spell binding.

Therefore, the combination of the two spells increased Merlin's ability to bind ice spells by several times, this time, Merlin was very careful, but it only lasted for a while, and then the spell could not be stabilized, and completely collapsed.

Merlin already had some confidence in his heart, and he knew that it was impossible for the spell to be completely fused now. However, with regular practice, it is possible to do it, but it is only a temporary fusion between spells, not a complete fusion of spell models.

When fighting with an opponent, even a spell that is temporarily fused can increase in power, and it will definitely take advantage of it unexpectedly.

"I didn't expect that cultivating magic energy would have such an unexpected gain. ”

A smile appeared between Merlin's lips, and the spells fused, even temporarily. It was also quite a shocking and unexpected discovery. In the past, when he cultivated his demonic energy, he didn't have this kind of accident at all.

Maybe it was because his mental power was weak at the time, or because the spell level was not high enough, or because the magic energy was not perfect enough, etc. In a word. Whatever the reason. Spells can be fused temporarily, as long as you continue to practice, the time for spell fusion can be extended. Merlin's strength will be raised to a very terrifying level!

After cultivating the six systems of magic energy, at present, among the spells of each line of Merlin, there is fusion magic energy, which can be regarded as extremely complete, and if he becomes an archmage in the future, he will definitely become the top and pinnacle archmage.

But now, Merlin still needs to use the psychedelic heart to increase his mental power, and it is best to be able to break through to the seventh level of spiritual power in one fell swoop, break free from the shackles, break the bottleneck, and achieve a qualitative change in spiritual power!

Only when his spiritual power reaches level seven can Merlin be able to construct the remaining level five ice spells and lightning spells, and truly become a powerful level five spellcaster!

"Huh".

Merlin took out the psychedelic heart from the ring, and suddenly the whole room seemed to be in a dream, colorful colors, very dreamy.

This is also the characteristic of the psychedelic heart "psychedelic", but Merlin's spiritual power is now quite powerful, and a single psychedelic heart naturally cannot affect Merlin.

"That's the psychedelic heart. ”

Merlin took a deep breath, he already knew how to use the psychedelic heart, so he used his mental power to quickly extend into the psychedelic heart.

Inside the psychedelic heart, Merlin felt as if he was in a dreamlike world, full of colorful bubbles, and enveloped every trace of Merlin's mental power.

It's like a world of bubbles, colorful, the number of bubbles is very large, almost thousands, everywhere, Merlin's spiritual power is a lot, every trace of spiritual power is as small as a silk, but it is still wrapped in bubbles in the sky, and the wrapped spiritual power, each like a silk, began to expand wildly.

Every trace of spiritual power expands by one to several times, and once the spiritual power is fused and the psychedelic heart is withdrawn, it is almost equivalent to the entire spiritual power increasing several times.

Merlin then felt the magic of the psychedelic heart, no wonder so many powerful spellcasters were competing for the psychedelic heart, but in the end Merlin took it into his hands.

"Hoo ......"

I don't know how long it took, Merlin let out a long sigh of relief, and then he looked at the psychedelic heart, and actually shrunk a big circle.

"Spiritual power is always illusory, but once it becomes the seventh level, it can be transformed into substance, and it can interfere with matter!"

Merlin always remembered that the seventh level of spiritual power was a watershed, and once it was reached, the spiritual power was no longer ethereal, but could interfere with matter, although the seventh level was only between illusion and substance, but already had the power to interfere with a little matter.

And once it reaches the archmage, its spiritual power will become very powerful, sometimes combined with some secret techniques of spiritual power, even more powerful than the power of some spells, spiritual interference with matter, any thought, can set off monstrous waves.

Even, those great legendary mages, a single thought, the starry sky can change color, the wind and clouds can change, and truly a single thought, can change a qiē!

However, these were still too far away from Merlin, and he only wanted to break through to the seventh level of spiritual power first.

The psychedelic heart was a little smaller, but Merlin's spiritual power had swelled several times, but there was still no sign of breaking through to the seventh level of spiritual power, his spiritual power was completely illusory, just like a transparent mist.

Merlin didn't care, he knew that it was very difficult to break through to the seventh level of spiritual power, because this was a qualitative transformation, from virtual to real, although it was only semi-substantial, it was also very unique, and the spiritual power required was very huge.

So, he continued to extend his spiritual power into the psychedelic heart, and began to grow his spiritual power wildly.

As time passed, the psychedelic heart grew smaller and smaller, from the size of a fist to the size of an egg, and after a while, it was almost the size of a finger.

And Merlin's spiritual power has gradually become extremely viscous, as if it has been transformed from gas to liquid, and it is gradually "liquefiing", Merlin knows that this is the key to the transformation of spiritual power into a seventh-level spiritual power, and if you want to transform into a seventh-level spiritual power, you have to mobilize your spiritual power, spin wildly, and form a round ball in the sea of knowledge.

This spiritual sphere is called the spiritual heart, which is the foundation of the spiritual power of all spellcasters, once the spiritual heart is formed, the amount of spiritual power depends on the specific situation of each spellcaster.

At this time, some spellcasters have condensed their spiritual hearts for some special reasons, and even seventh-level spiritual power can be comparable to those eighth-level or even ninth-level spiritual power.

That kind of spiritual heart is called a special spiritual heart, and Merlin not only wants to form a spiritual heart, but also wants to condense a special spiritual heart.

I don't know how long it took, the psychedelic heart in Merlin's hand has completely disappeared, and has been completely absorbed by Merlin's spiritual power, even Merlin doesn't know how much his mental power has increased now.

He can only feel that his spiritual power is too huge, and the transparent spiritual power can only be felt by him, and at this time, it is the moment to condense the spiritual heart.

"Boom".

Merlin mobilized his spiritual power, and suddenly, the unimaginably large spiritual power began to rotate gradually, and the speed became faster and faster, from colorless and transparent spiritual power to gradually rotating, and a faint trace of silver light appeared.

Soon, the spiritual power turned from virtual to real, condensing a small spiritual seed as small as sand, which can be regarded as the most basic spiritual heart!

Merlin was overjoyed in his heart, and finally condensed the spiritual heart, but this was far from enough, his spiritual power was still very large, and all the spiritual power had to be gathered in the spiritual heart, so that he could successfully condense the spiritual heart.

So, as more and more spiritual power gradually converged into the spiritual heart, soon the spiritual heart had become larger, from the size of gravel, gradually to the size of soybeans, and finally the size of a baby's fist, and it seemed to continue to grow.

It's just that after not much spiritual power, Merlin opened his eyes violently, and there seemed to be a trace of silver light in his eyes, this is because his spiritual heart has been condensed, exuding a silver light in the sea of knowledge.

Spiritual power affects Merlin all the time, therefore, he didn't control it, and a silver light appeared in his eyes, and with a spiritual heart, he could even stir the air slightly in a thought.

"Hoo ......"

Merlin used his spiritual power to disperse some of the surrounding air, and immediately formed a cool breeze, which was to use spiritual power to interfere with matter, forming a breeze.

However, Merlin's spiritual power can only do this now, and it can't be done by moving some heavy objects slightly, so he needs to constantly enhance his mental power.

But knowing the spiritual heart the size of a baby's fist in the sea, Merlin is still a little dissatisfied, if he wants to condense a special spiritual heart, if he lets the spiritual heart expand like this, there will be a limit in the future, and when the time comes, when the limit is reached, he must break through to the eighth level, and at that time, his spiritual heart may not be able to contain much spiritual power.

Therefore, Merlin also needs to compress the spiritual heart, and do it immediately when he thinks of it, Merlin closes his eyes again and begins to mobilize the spiritual heart again, spinning at an even more terrifying speed.

Compress, compress, compress, compress! Merlin tried his best to compress the spirit heart the size of a baby's fist, and sure enough, the volume of the spirit heart quickly began to shrink, indicating that Merlin's spirit heart was indeed far from being compressed to the limit.

Soon, the spiritual heart was compressed by Merlin to the size of a ping-pong ball, and the close flow of spiritual power in the spiritual heart was even more terrifying.

Such a high-intensity compression shows that Merlin's spiritual heart still has a lot of room for growth in the future, and it can be regarded as a very powerful special spiritual heart that can be fused with more spiritual power......!
