Merlin's spiritual heart is now at least half smaller than before, but because of this, the spiritual heart can hold more spiritual power, at least twice as much as before.

Such a huge amount of spiritual power is enough for Merlin to have a spiritual power comparable to that of a ninth-level spellcaster at the time of the seventh-level spiritual heart.

And the general spiritual power, the spiritual power is very powerful, far beyond the ordinary spellcaster, but Merlin's spiritual power is even stronger than those with strong spiritual power, Merlin compressed the spiritual heart to almost the limit, even the Orsaith mage, did not compress to the limit.

In a certain way, Merlin is already much better than Master Ossaith in terms of starting, and his cultivation of Nine Heavy Strikes should be smoother than Ossais.

And in fact, it is true, Merlin is constantly cultivating the explosion theory and compressing the spiritual heart, but also cultivating the nine heavy strikes, and the first three of the nine heavy attacks are relatively simple.

Although a huge amount of spiritual power is also needed, with the current spiritual power of Merlin, it is enough, therefore, Merlin has cultivated the first three layers of the first nine heavy attacks in a very short period of time.

"Give it a try!"

After Merlin finally compressed his spiritual heart to the limit, he secretly unleashed nine heavy blows, invisible spiritual power, and slammed into a boulder outside the house.

"Bang".

A dull voice sounded, the spiritual power was invisible and invisible, and after breaking through to become a seventh-level spiritual power, it had a transformation, and it was able to interfere with tangible things with invisible power, turning from virtual to real, which was very magical. It's hard to prevent.

One attack. The boulder shook only slightly. It seemed to have been under a huge attack, and this rock was one of the hardest rocks, and even some level 7 spells couldn't even shake it.

It's just that because it is difficult to decompose, the rock cannot be used as an alchemy material, only as a decoration, but now it can be used to test the power of Merlin's Nine Heavy Strikes.

Once it didn't work, Merlin continued to perform nine blows.

"Boom".

Another dull crash. The boulder trembled as if it had been attacked by an invisible force surging from all directions, but it didn't seem to be ready to be completely shattered.

"Triple Blow!"

There was an invisible fluctuation on Merlin's body, and the fluctuation of spiritual power could not be seen with the naked eye, but Merlin could clearly sense that a terrifying shock like the ripples of water slammed into the boulder.

"Click".

This time, the boulder did not have any luck, and was directly crushed by the powerful forces in all directions. Turned into a pile of stone dust.

I saw that it was a boulder that was extremely hard just now, but now it was a pile of powder. Merlin couldn't help but be a little frightened, the attack of the spiritual secret art is weird, shadowless, and unguardable, very distinctive, and very different from the spell attack of the caster.

Especially the nine heavy blows, one heavy is stronger than the other, Merlin's triple attack is already comparable to the power of the eighth-level peak spell, and few eighth-level mages can withstand it.

This kind of power even surpassed the triple attack that Master Ossaith had cast at the beginning.

The biggest feature of the spiritual secret technique of Nine Double Strikes is that no matter who it is, no matter how powerful the spiritual power is, the power of the same triple attack is actually about the same.

And Merlin, for the time being, can only cultivate to the triple strike, as for the quadruple strike, Merlin's current spiritual power is not enough, and generally requires the spiritual heart to transform into an eighth-level spiritual heart before he can cultivate.

However, Merlin's spiritual heart is very special, after the continuous compression of the top-level secret art explosion theory, plus the original Merlin's spiritual heart is compressed very strongly, such a spiritual heart is already close to the theoretical compression limit.

Therefore, perhaps when Merlin once again accumulated his spiritual power to the limit of the seventh-level spiritual heart, he would be able to cultivate the quadruple attack.

"Hoo ......"

Merlin let out a long breath, feeling that in the past few months, he had hardly left the room for half a step, but the harvest was also quite large, and Merlin was very satisfied.

"It's time to get out!" Merlin stood up, left the room, and flew straight towards Master Atto's palace.

In the palace, when Master Yato and Master Mogan were exchanging ideas about the Law of Condensation, Master Yato suddenly stopped and said to Master Mogan with a smile: "Merlin has come here, it seems that he has gained a lot!"

As soon as he finished speaking, the palace gate was slowly pushed open, and Merlin had a smile on his face, and bowed slightly to Master Atto and Master Mogan.

Master Mogan looked at Merlin for a long time, and there was a hint of surprise in his eyes, and he seemed to see some clues, but he didn't ask about the spiritual secret arts, in Master Mogan's opinion, no matter how magical the spiritual secret art is, it can't become a great legend after all, so it has no effect.

In the eyes of Master Mogan, Merlin has long been regarded as a genius mage who has the hope of becoming a great legend in the future, and Merlin's efforts should be towards becoming a legendary mage.

"Master Ato, I don't know where Master Ossaith is? I want to express my gratitude to Master Ossaith in person. ”

Merlin also wants to leave the Atherto plane, his purpose of coming to the Asternautic plane this time has been achieved, and after getting the spiritual secret, he naturally has to thank Osaith.

However, Master Atto shook his head helplessly and said, "Master Merlin, I'm afraid you won't be able to do it. More than a month ago, Master Ossaith had left the Altar Plane and traveled to the vast void realm, he wanted to break through the shackles, improve the system of spiritual powers, and achieve a legendary ......"

Speaking of which, Master Atto also looked quite helpless, of course he was unwilling to let Mage Ossaith leave, after all, in the Atherto plane, Ossaith is one of the top archmages, and with him sitting on the Atherto plane, Master Atto will be much easier.

And this time, the departure of Ossaith is obviously a bit tragic, if Ossaith can't break through in the future, I'm afraid he won't return to the Atto plane.

"Mage Ossaith is gone?"

Merlin's mind was full of Ossaith's hopeful face, and Merlin knew that Ossaith had worked all his life to perfect the system of spiritual powers, but until now, there had been no progress.

The only achievement is to create his own explosion theory and nine strikes, especially nine strikes, even Ossaith himself has only cultivated to seven strikes, once he breaks through the seven strikes and reaches eight or even nine strikes, he may be able to rival the real legend and fulfill Ossaith's lifelong wish.

This time, Ossaith should be desperate, hoping that with the help of the vast void realm and thousands of planes, he can have a chance to cultivate to an eight-fold attack or a nine-fold attack.

If there is nothing to gain from this trip, Ossaith will not come back.

"It's a pity!"

Merlin shook his head slightly, and then looked at Master Mogan, at this time, it was time for Master Mogan to say goodbye to Master Yato.

However, after waiting for a while, Mage Mogan did not speak, but said in a deep voice: "Merlin, I am going to recommend you to enter the City of Upanishads!"

"The Upanishads?" Merlin asked softly with a look of confusion on his face, which he had never heard before, "Mentor Mogan, what is this Upanishads?"

Mage Morgan didn't speak, but Master Atto laughed: "Haha, Merlin, you are really lucky, in order to send you into the City of Upanishads, Morgan has to use up the only recommended place!"

"It's just a quota! Merlin has entered the City of Upanishads, and I believe that this quota will also have a great effect!"

Master Mogan looked at Merlin and said, "Merlin, the City of the Upanishads is a plane created by the three supreme mages, and in the vast void realm, there are three Upanishads in total, all of which were created by the three supreme mages. It contains all the things that a spellcaster needs, a great Upanishads mage, a plane created in order to cultivate the strongest of the spellcasters! A genius like you, even in thousands of planes, is very difficult to appear, if you don't enter the Upanishads city, you don't know how many detours you will have to take. ”

Speaking of this, Merlin was already shocked in his heart.

The three arcane mages, the creation of the plane, and so on, are almost all secrets, and only those great legends, or spellcasters who are very close to the great legends, or those archmages who are very powerful in the endless plane, can know these secrets.

Create a plane, these four words shocked Merlin fiercely, even if it is a titled legend, it can't create a huge plane, maybe a relatively perfect space can still be created, as for creating a plane, it is beyond the understanding of the great legendary mages.

Only the strongest Upanishads can have the power to create a plane like this, so it's no wonder that the Upanishads are all named "Supreme".

That represents a real pinnacle that cannot be surpassed!

Merlin knew very well in his heart the greatness of this city of mysteries, I am afraid that it was the place where the true top geniuses gathered in the void realm, among the thousands of planes.

With the most suitable plane for the caster, as well as some of the richest resources in the caster's world, and some of the top knowledge of spells, runes, alchemy, potions, etc., Merlin will definitely advance by leaps and bounds if he enters it.

Moreover, being able to get together with some spellcasters who were far more talented than Ehil was hard for Merlin to imagine what it would be like.

For a long time, Merlin didn't think that he would be excited about anything, but now, after knowing the Upanishads, especially after Master Morgan planned to use up the only recommended quota that even legendary mages had to use, Merlin was also uncontrollable excited.

This is an opportunity not to be missed!

[The hillbilly has entered the city...... Merlin began to slowly get in touch with the core of the caster's civilization, which is also the rhythm of the mage officially entering the middle stage, ask for a monthly ticket, recommend a ticket, and smash it out if you have a ticket, this section of the Upanishads City, Lao Yue needs to think carefully, and it must be written well and wonderfully!] (To be continued......
