Inside the ancient castle, in a dark quiet room.
On a square table, seven old and new parchment manuscripts were neatly arranged.
Meng Yan stood by the table, his gaze sweeping over each of the seven parchment manuscripts.
He had already carefully studied these parchment manuscripts with the help of his Mutated Spiritual Power.
Of the seven parchment manuscripts, three were written in Demon language, and four were written in an ancient language of the White Eagle Federation.
The Demon language, besides Demons themselves, could only be understood or mastered by worshipers of Demons or Demon Magicians among humans.
Ryan and the Green Evil Spirit did not know the Demon language.
Naturally, Meng Yan didn't either.
The three parchment manuscripts written in the Demon language were temporarily of no use to him.
The ancient language used in the other four parchment manuscripts happened to be one of the languages the Green Evil Spirit had once mastered.
Previously, Meng Yan had absorbed all of the Green Evil Spirit's memories through the Godhead.
Now, he only needed to spend some time carefully reviewing the Green Evil Spirit's memories from when he had studied this ancient language.
Relying on his powerful Spiritual Power, he completely mastered this relatively rare ancient language in just one hour.
Each of these four parchment manuscripts documented a ritual for summoning an ordinary Demon.
As long as the ritual was strictly arranged according to the requirements, there was a high probability of summoning an ordinary Demon.
One parchment manuscript represented one method of summoning an ordinary Demon.
However, Meng Yan only intended to try three of the rituals, discarding one of them.
The four parchment manuscripts corresponded to four types of ordinary Demons: one was a physical Demon, and three were spiritual Demons.
Physical Demons, like werewolves, possessed powerful bodies.
For extraordinary creatures with physical bodies, Meng Yan needed to kill them or use special methods to extract their souls before the Godhead could absorb the extraordinary creature's soul.
Spiritual Demons were equivalent to a different kind of soul body.
And as long as it was a soul body, once touched by Meng Yan, it could be immediately absorbed by the Godhead.
Therefore, even if the summoned Demon was not an ordinary-level Demon, Meng Yan would not be defenseless when summoning a spiritual Demon.
As for physical Demons, Meng Yan couldn't guarantee his safety.
If he accidentally summoned a physical Demon equivalent to a Blood Clan Viscount, he would have little power to resist at this stage.
This was why Meng Yan had to be cautious.
The Demon Clan was exceptionally cunning.
Some summoning rituals were deliberately spread by the Demon Clan.
This was for 'fishing'.
A ritual that appeared to summon an ordinary Demon might unexpectedly summon a Lesser Demon, or a Middle Demon, or even a higher-level existence.
This was not impossible.
Lesser Demons were equivalent to Blood Clan Viscounts, and Middle Demons were equivalent to Blood Clan Earls, neither of which Meng Yan could currently contend with.
In the Green Evil Spirit's memories, there was once such a record.
An ancient human Demon Magician used a ritual for summoning a Lesser Demon and 'accidentally' summoned a Demon King's clone.
Ultimately, the entire city where the human Demon Magician resided was devoured by the Demon King's clone.
A Demon King, that was an existence equivalent to a Blood Clan Prince.
Even a clone of a Demon King was not something an ordinary human Demon Magician could deal with.
It was only because Meng Yan had the Godhead as a trump card; otherwise, even spiritual Demons, he would not dare to summon casually.
As for whether a ritual for summoning a spiritual Demon could summon a physical Demon.
Meng Yan didn't need to worry about this aspect.
The rules for summoning Demons involved all aspects and were extremely complex.
Powerful Demons could disguise their summoning rituals as lower-level Demon summoning rituals by concealing themselves or simplifying the ritual.
However, they could not change the most basic part of the rules in the summoning ritual.
A ritual for summoning a spiritual Demon could never, under any circumstances, summon a physical Demon.
Meng Yan looked at the three parchment manuscripts that recorded the rituals for summoning spiritual Demons.
Three spiritual Demons.
If all went well, after the Godhead absorbed these three spiritual Demons.
His Spiritual Power sensing range should break through one hundred meters and reach the level of a Blood Clan Viscount.
His control over the Godhead would also increase by a level, allowing him to release more pure energy.
Currently, under Meng Yan's control, the Godhead continuously released wisps of pure energy every moment, integrating into his physical body and Blood Core.
Although the efficiency of his physical body and Blood Core absorbing pure energy was not very high when he was not in a dormant state.
However, accumulated over time, it could still lead to considerable improvement.
After Meng Yan's control improved, more pure energy could be released, and this gradual accumulation of improvement would become even more terrifying.
Nine years would definitely be enough for him to gain powerful strength and break free from Viscount William's control.
Meng Yan picked up one of the parchment manuscripts that could summon a spiritual Demon.
This parchment manuscript was very old, but the writing on it was exceptionally clear.
Meng Yan looked at the words on it and walked towards a wooden cabinet nearby.
This wooden cabinet was about two meters high, looking classical and elegant, with intricate patterns carved on its surface.
There were two other similar wooden cabinets next to it.
Each wooden cabinet contained various materials needed for the Demon summoning ritual.
These were prepared by John at Meng Yan's instruction.
Opening the wooden cabinet on the right, the contents looked strange.
There were two black goat horns, a bowl of virgin's blood, two deciduous incisors from a thirteen-year-old boy, black ink mixed with the blood of an adult man, some precious medicinal herbs, ordinary sheepskin, and so on... Meng Yan meticulously prepared everything according to the ritual's requirements.
He placed the various items in their corresponding positions as described in the parchment manuscript.
Since the parchment manuscript contained residual Demon aura, it indicated that someone had successfully summoned a Demon using the parchment manuscript.
Therefore, no matter how strange the ritual requirements were, Meng Yan had no doubt about the authenticity of the summoning ritual.
After some time, Meng Yan finally placed all the strange items in their correct positions.
Then, he used the blood-mixed black ink to draw a strange symbol on the ground.
After drawing it, Meng Yan clapped his hands.
Only the last step remained.
He first stepped back, then leaned slightly forward.
He chanted:
"Following ancient vows, I seek your form from the endless abyss.
Souls are your food, mortals tremble before you.
Despair is the best seasoning, weeping is a moving melody.
A humble mortal, I summon you here.
Great Soul-Devouring Demon, Kevin Duane.
Descend, descend, descend!"
It must be said that even for a Demon of the lowest rank, the accompanying summoning incantations still had a certain flair.
This could also be considered a characteristic of the Demon Clan.
As soon as Meng Yan's words fell.
In the quiet room, the strange symbol on the ground lit up with a ghostly blue light, and all sorts of summoning materials trembled slightly, then, under an inexplicable gravitational pull, gathered towards the center.
Boom!
With a loud bang, all the materials exploded, turning into powder, which then rapidly converged.
At the point where the powder gathered, a mass of black demonic energy suddenly appeared.
After this demonic energy consumed all the powder, it suddenly dispersed.
A black shadow appeared in its original place.
It appeared!
Meng Yan's spirit was invigorated as he saw the black shadow.
