No matter what kind of magic trick it is, there are three basic conditions that are required to successfully unleash it.

One: The amount of power required to activate the technique.

2. The procedure required to initiate the procedure.

Three: The commands required to initiate the technique.

The first condition refers to mana, and without enough mana, no matter what kind of magic it is, it cannot be successfully activated.

The second condition refers to the spell itself, i.e., the magic array, rituals, magic materials, and so on.

The third condition refers to spells and spells.

Magicians need to have the ability to construct, establish, and depict spells, and then chant spells that can interfere with phenomena, and inject the required magic power into the spells to generate magic.

Although there are some conditions for magic to be activated, and the external environment will also affect the activation of magic, basically speaking, as long as the above three conditions are met, then the magic can be launched smoothly.

And "Call of the Heroic Spirit" is the same.

Leaving aside the magic of the decisive battle used to save the primate world, the reason why the usual "Summoning of the Immortal" cannot be successfully launched is simply because the magic required is too amazing and the summoning ritual is too intricate.

In other words, the first and second conditions cannot be met, so the summoning will not be successful.

Therefore, the rituals of the Holy Grail War need to be supplemented by the Holy Grail.

Because only the "Holy Grail" can meet the magic required for summoning, and only the "Holy Grail" can realize the overly complicated large-scale ritual, so that people can directly achieve the first two conditions, and finally only need to chant the spell correctly, and then trigger the summoning system of the "Holy Grail" with the correct procedures, then the summoning can be completed.

The same is true of the Chaldean summoning system, which combines the power of the entire facility to run the entire ritual, and then achieves the first two conditions by converting electricity into magical power, so that the Chaldeans can summon the servant.

It's just that, compared to the miracle of the "Holy Grail", the Chaldean summoning system has many limitations and imperfections because it is composed entirely of human resources, so it has been improving.

On the other hand, Luo Zhen, because of the relationship between the "Heart Eye" and the arrival of the divine domain, no matter how complicated, intricate, and sophisticated the ritual is, he can rely on himself to construct it perfectly.

A large-scale ritual that required the Holy Grail and all the resources and manpower of the entire Chaldea to be realized, Luo Zhen could complete it by himself.

That's why Skaha was amazed by Rogen's skills in the first place.

Therefore, Luo Zhen already has the technology to establish the technique.

In this case, if the summoning is not successful, it means that Luo Zhen's strength is insufficient.

In other words, the magic is insufficient.

Otherwise, Luo Zhen wouldn't have made a mistake in chanting the incantation, right?

In view of this, Luo Zhen's summoning will fail, just because the first condition has not yet been met.

It's also a matter of course to think about it.

"Regardless of the magic power to maintain the existence of the Servant and the battle, the magic power consumed to summon and the spirit core and spirit base required to form the Servant alone cannot be achieved by human beings, even if you use the secret technique that greatly increases the magic power, plus the magic power of the spell, it can only be regarded as barely satisfied."

Regardless of the fierce conflict on the battlefield, in order to seize the only chance to win, Skaha explained to Luo Zhen wholeheartedly.

"I want to open the passage to the 'seat' that connects to the outside of the world, call up the records there, and then copy its soul and summon it to this world, and I want to know how much magic power is needed, not to mention the spiritual core and spiritual base of the servant."

This is still the magic required by the Servant of the usual specifications.

If it was the Heroic Spirit that Luo Zhen had been summoning, he might need to release the Three Strokes Spell and the amplification of the [Red Wing Array] at the same time, so that the conditions could be met.

Of course, this is only possible.

Therefore, Luo Zhen's summoning has always ended in failure.

And as long as the problem of magic power is not solved, no matter how skilled Luo Zhen is, he will not be able to realize the summoning.

This is not to say that Luo Zhen's magic power is too weak, but it is that the magic power required to summon the servant is too much, unless it is an almost infinite magic power like the "Holy Grail", otherwise, even the Chaldeans need to carefully weigh whether they should consume a lot of resources and summon the servant.

The demands on mana, and the technology needed to establish rituals beyond the reach of humans, make it nearly impossible for humans to summon servants on their own.

Luo Zhen arrived in the Divine Domain because of the "Heart Eye", so he met the conditions of the latter, but the former was really powerless.

In any case, the magic circuits of magicians are inherently fixed, and the magic power they can hold cannot be changed at all.

It was already a miracle that Luo Zhen was able to use the Great Source Magic Power with the Heart Eye, and then use the Red Wing Array to increase the magic power.

In a word, humans cannot complete the mystery of "Call of the Heroic Spirit" alone.

This time

"You'll need to use other powers, Lorelei."

Skaha gave Rozhen this advice.

This made Luo Zhen couldn't help but be silent.

Immediately after, Luo Zhen took out the things that Skaha had given him not long ago from the inside of his coat.

"Zheng"

Bright light is circulating.

Luo Zhen held the dazzling golden cup, his eyes flickering slightly.

———— "Holy Grail".

Created by Solomon, it was sent to this age to become a relic of the power that created this peculiar point.

After defeating Ku Churin, Skaha gave the "Holy Grail" to Rogen.

"Use the magic inside."

Skaha spoke.

"That way, you'll be able to summon success."

Leaving such words, Skaha turned around, no longer paying attention to Luo Zhen, as if he had given Luo Zhen all the choices, and suddenly jumped up, like a magic spear, pierced into the battlefield, and joined the onslaught on Solomon.

It's an onslaught, but it's just buying time.

A group of servants seemed to have a tacit understanding of dragging Luo Mon, as if they understood what Luo Zhen was going to do, whether it was martial arts, tactics, magic or treasures, they were all liberated with all their might.

"Seniors"

The familiar girl's low moan also broke into Luo Zhen's ears, making Luo Zhen hold the miracle in his hand tightly.

"Burning people"

This is a great undertaking undertaken by Solomon to deny humanity.

"Mythical Wars"

This is Ku Churin's struggle to wipe out the humanity of the continent.

Whether it is in the face of human reason or mythological wars, human beings are like tiny ants, and can only be forced to endure suffering.

Even the Chaldeans were able to send only one human to each of the anomalous points in order to grasp the last glimmer of hope.

Solomon said that too, right?

"Human beings must be killed, not burned."

moreover

"In my mythology, there is no need for a human like you to exist."

This is what the virtuous king, who is God's agent, declares.

If the so-called myth refers to the total denial of human beings

"Give me the power to destroy myths now!"

This is the wish that Luo Zhen made to the Holy Grail.

"Zheng ————!"

In Luo Zhen's hand, the golden urn bloomed with unprecedented light.

meanwhile

"Zheng ————!"

On Luo Zhen's right hand, the golden ring also shone brightly, becoming extremely dazzling.

This scene attracted the attention of everyone present.

Including Solomon.

And then

"That's!?"

When Solomon saw the shining ring in Luo Zhen's hand, one of his eyes instantly widened, revealing shock, consternation, and even rage that he had not seen so far.

And at this time, Luo Zhen had already begun to sing.

"———— proclaimed ————"
