Nowadays, Luo Zhen not only has a huge knowledge of spells, but also has a large amount of magic knowledge, and his attainments in various techniques are unparalleled in the world, only in terms of the amount of knowledge and the number and types of spells, not to mention modern magicians, even the magicians of the god generation are not as good as Luo Zhen.

Therefore, Luo Zhen naturally would not be unclear about why his "Heroic Spirit Summoning" failed frequently.

Among them, of course, there is the problem of catalysts mentioned by Skaha.

If there is no catalyst,,That "Heroic Spirit Summoning" will only summon the best servant with the master.,The random nature is relatively large.,The sorcerer itself is out of such a nature.,Can't summon the designated servant at all.,Let alone according to their own ability to cycle from weak to strong.,Gradually summoned.,So,If the summoned object is too strong.,It's a matter of course that it will fail.。

In addition, the problem of magic power is indeed very strict, and Luo Zhen has no choice.

Generally speaking, summoning servants requires complex magic rituals, which are mysteries beyond the reach of human beings, and only the assistance of the "Holy Grail" can make it possible, and the summoning itself is the work carried out by the "Holy Grail", otherwise human beings would not be able to hold such a large-scale ritual at all.

Chaldea systematized the summoning of servants through various fields of technology, and eventually led to the imperfection of the Heroic Spirit summoning system, so far there have only been three successful cases, and one is still missing, and one can only become a sub-servant, only Leonardo da Vinci's summoning is successful, proving that it is not yet mature.

This is also the reason why Luo Zhen has never borrowed the Chaldean Heroic Spirit Summoning System to summon the second contract servant.

"Although the Chaldea has made some analysis after obtaining the 'Holy Grail' with various special points, and has gradually perfected the Heroic Spirit Summoning System, it would be better if I could achieve the summoning myself."

Although the summoning achieved by himself cannot provide magic power with the help of Chaldea, at that time Luo Zhen will bear all the mana consumption required by the Servant's current world, and the burden will be very large, if the "Heart Eye" is not transformed, even Luo Zhen does not have the confidence to do this, but if it is now, in the situation of being able to attract the magic power of the Great Source, it should be able to barely afford it.

That's what Luo Zhen thought, and only then did he start to contact the technique of "Heroic Spirit Summoning".

As a result, Luo Zhen found out that this attempt...

"It's really harder than I thought."

Luo Zhen is really helpless.

In addition to the fact that this technique cannot summon the designated servant, so the randomness is too strong, resulting in a low success rate, the main reason for the failure is the problem of magic.

Even though Luo Zhen relied on his extraordinary skills and abilities to master the "Summoning of the Immortal", a large-scale ritual that could not be achieved by human beings, and could directly connect to the records on the "Throne of the Immortal" to achieve the purpose of summoning, as Skaha said, the magic required to summon the Servant was extraordinarily large, and ordinary magicians could not pay for it at all.

The spiritual base of the Servant requires a huge amount of magic power.

Forming the Servant's Spiritual Core requires a huge amount of mana.

It takes magic for the Servant to maintain the present world.

It also takes magic to keep the Servant powerful.

In the Holy Grail War, in addition to maintaining the mana required for the Servant's current realm and providing the mana required for battle, the rest of the consumption can be paid by the Holy Grail, and although the burden cannot be said to be small, it is not too large.

If it is in the Chaldeans, then all the consumption of magic power can be provided by the Chaldeans, and the magic power of the master can be used to improve the power of the servant, so that as long as the person with the qualification of the master will be summoned to the Chaldea at the beginning, even ordinary people can participate in the task of laying the foundation of human affairs, which can be seen.

But if Luo Zhen performs the "Heroic Spirit Summoning" himself, all the magic required for this will have to be provided by himself.

In this way, even if you can attract the magic power of the Great Source, it is not so simple to summon a rider.

Now, Luo Zhen needs to think of himself as the Holy Grail system, completing all the work and work required for the summoning.

It's easy to say, but how can it be easy to accomplish?

However, what Luo Zhen is doing is not an ordinary summoning ceremony.

That's why Skaha couldn't help but look at her with such delight.

"You're doing the technique of 'Séance Ritual - Summoning of Heroic Spirits', not the normal 'Summoning of Heroic Spirits', right?"

Skaha actually said such a thing.

"Do you know about the séance?"

Luo Zhen was stunned at first, and then couldn't help but be surprised.

No way.

This is something that even the previous Chaldeans did not know.

"Originally, 'Call of the Immortal' was a decisive battle magic used to save the primate world."

Skaha reveals such a secret.

"Life and death are the basic forms of existence of primates, and the world sometimes encounters catastrophes that hinder its own development, so when the world encounters a crisis, the great magic used to defeat the catastrophe that hinders the development of the primate world comes into being."

Its origin can be traced back to the gods and above, and even when the heavens and the earth first opened.

It is also recorded in the countless books of the Clock Tower that the "Call of the Heroic Spirits" is to summon and protect the survival of mankind and make them manifest.

And the Heroic Spirits used to deal with the Great Disaster only had seven horses at the beginning.

They exist as the seven Heavenly Messengers chosen by the Roots, and stand at the apex of all heroic spirits.

"Humanity attempted to reach the vortex where the Root is located for its own convenience, and developed the ritual of the Holy Grail War, which was simply a summoning system that reduced this magic."

Skaha is as if he could see through the past and the future.

"I'm afraid that the Chaldean summoning system is the same thing, descended from the real 'Heroic Spirit Summoning', right?"

Exactly.

If the true "Calling of the Heroic Spirit" is the magic of origin used to deal with the enemies of the world, then the modern "Calling of the Immortal" is the product of downgrading it and using it to achieve its own purpose.

The rituals of the Holy Grail War are so.

The battle of Guardian Renli is like this.

Therefore, whether it is the summoning system of the Holy Grail War or the summoning system of the Chaldeans, they all have their flaws to a certain extent, not to mention summoning the Seven Horsemen of the Origin, or summoning ordinary heroic spirits There are great limitations.

Luo Zhen has known this before.

Because...

"You are using the true Calling of the Heroic Spirit, one of the greatest mysteries in this world."

Skaha looked directly at Rogen and asserted.

"That's why your summoning has never been successful, in addition to the scale of the ritual being too large, the most fundamental reason is that its difficulty is different from the ordinary 'Summoning of the Heroic Spirit'."

This is an important reason why Luo Zhen's summoning has been failing.

"It is not an easy thing to accomplish such a great feat as a human being."

Skaha said this, but his words were full of joy.

"And although you failed, you did master the technique, in you, I actually saw the possibility of success, it seems that I underestimated your talent a little, maybe in the field of summoning, you have a talent that can be called a god realm."

In the face of such a genius, Skaha almost couldn't help it.

"I can't help but make people want to train you well."

Skaha stared at Rozhen, and his eyes began to glow.
