Arlen watched the silver-haired figure fleeing in defeat, shook his head, and smiled.
It was the first time he had ever seen the usually composed Grayfia so flustered.
"However, how should I improve my strength now?"
Touching his chin, Arlen fell into deep thought.
Speaking of becoming stronger, there were indeed many avenues he could pursue in this chaotic world.
But because this was a fusion of multiple anime worlds...
Heaven only knew how much the original plot had changed. Relying on foreknowledge was risky.
"By the way... do I really not have a Cheat?"
The instant his voice fell, Arlen heard a distinct ding sound.
Immediately after, a semi-transparent virtual panel slowly floated into his field of vision.
[Arlen Lucifuge]
[Race: Progenitor Devil]
[Level: LV30]
[Authority: Progenitor Devil Transformation]
[Skills: Devil Contract, Devil Summoning]
"This system panel is really crude," Arlen muttered a complaint, but his eyes were glued to the text.
In the next moment, information regarding these abilities naturally surfaced in his mind.
[Devil Contract]: A method of accepting Servants, similar in effect to the Evil Pieces of the Underworld.
But the key difference was...
The Devil Contract could not only reincarnate any race into a Devil, but it would also grant them a leveling system panel.
Due to differences in the aptitude of some Servants, they might even acquire special skills unique to them.
Moreover, Arlen could improve his own strength through leveling up by fighting monsters and receiving a portion of power feedback from his Servants as they grew stronger.
[Devil Summoning]: A contract that could be distributed across the myriad worlds.
As long as someone summoned him, Arlen could cross over to other worlds to fulfill their request.
As for [Progenitor Devil Transformation]...
It was a transformation ability that briefly liberated the latent power within his bloodline, granting him immense strength.
In addition to that, the information revealed a startling fact.
Even if he didn't complete the Progenitor Devil Transformation, his very blood and body fluids were now supreme to other Devils.
At this moment, Arlen's expression hardened.
It seemed he would have to be very careful in the future.
He didn't want to be locked up by certain powerful women for some twisted "breeding" experiments.
"However, gaining strength just by accepting Servants is really nice," Arlen mused.
He stroked his chin, a calculated glint flashing in his eyes.
"The only problem is that my Servants need to have high aptitude."
"Otherwise, they cannot withstand the modification of the Devil Contract."
Thinking of this, Arlen's eyes lit up.
He seemed to have the perfect target right here.
...
"Nee-san, become my Servant."
Grayfia looked at Arlen, who had come to find her in her room, in silence.
This direct approach caught her off guard.
She smiled helplessly. "Arlen, I don't mind becoming your Servant."
"However, the Evil Pieces applied for you haven't been approved yet. You have to wait a bit."
"I don't need Evil Pieces. Nee-san just needs to agree."
Grayfia blinked, her expression somewhat confused.
Arlen looked at the Devil Contract skill flashing on his system panel.
This skill had a passive effect: it could sense people who had the aptitude to become his Servants.
As he expected.
Grayfia fit the criteria perfectly.
"Are you sure you aren't joking?"
Grayfia came back to her senses and asked, "Did you develop some new reincarnation technology?"
Arlen shook his head. "It should be considered awakening a certain inherent ability."
Grayfia revealed a look of realization.
The Devils of the Underworld were full of strange wonders. Many Clans possessed special demonic powers or unique abilities.
However, an effect similar to the Evil Pieces system—but innate—was something she was hearing about for the first time.
"Alright, I agree."
Grayfia asked curiously, "What do you plan to do?"
"Take off your outer clothes first."
Seeing Grayfia's face starting to turn red, Arlen hurriedly added, "I need to use my blood to engrave the Devil Contract directly onto your skin. The clothes are a bit in the way."
To be honest, he also felt this process sounded a bit suspicious.
But thinking about it carefully...
Teasing his future Servant—and future wife—seemed like not a bad idea.
"Okay."
Grayfia took a deep breath. Her fingers trembled slightly, but she didn't hesitate, slowly unbuttoning her dress.
Arlen watched Grayfia, who was clutching her clothes to her chest with flushed ears, and his heart began to beat faster.
If not for the need to perform the ritual, he feared he really wouldn't be able to control himself.
"Nee-san, I'm starting."
Arlen took a few steps forward and bit his index finger. Traces of pale gold blood seeped out.
Seeing this, he was surprised for a moment.
It seemed that after the awakening of his lineage...
His body had fundamentally changed. Even his blood was different now.
Thinking this, Arlen's movements did not stop. He pressed his blood-stained finger directly onto the smooth skin of her back.
The moment the blood made contact, it emitted a faint glow.
Bright golden light quickly outlined a complex, heart-shaped seal on her skin.
Countless mysterious characters flashed past within the light.
Grayfia felt as if she heard a shattering sound emerge from deep within her soul.
The world in her eyes changed instantly.
It was as if invisible shackles on her body had completely disappeared.
At the same time!
The moment Grayfia became his Servant, Arlen felt his physical fitness and demonic power begin to skyrocket like crazy.
The power that had just entered the High-Class Devil level was continuously breaking through, surging upward violently.
Seeing that Grayfia's reincarnation ritual hadn't ended yet, Arlen opened his own status panel.
[Arlen Lucifuge]
[Race: Progenitor Devil]
[Level: LV51]
[Authority: Progenitor Devil Transformation]
[Servant: Grayfia]
[Skills: Devil Contract, Devil Summoning, Infinite Demonic Power]
...
Looking at the text information, Arlen's pupils shrank.
Good heavens.
It increased this much?
It seemed the boost was directly related to Grayfia's own immense strength.
Then, Arlen looked at the new skill: Infinite Demonic Power.
[Infinite Demonic Power: Demonic power is endless and inexhaustible. Any consumption of demonic power can be recovered in an instant.]
Arlen looked at the skill introduction, his eyes brightening.
This skill...
It couldn't be called anything but broken.
From now on, he would never have to worry about running out of energy in prolonged battles.
"Arlen... are you a Satan-Class now?"
On the other side, Grayfia, who had just finished the reincarnation ritual, was dumbstruck.
What was happening?
Arlen, who was just a High-Class Devil moments ago, had his demonic power break through to the Satan-Class level in seconds.
Wasn't this too exaggerated?
"This is also my ability."
Arlen explained simply. "And you also have a new skill now."
"What do you mean?"
"Wait a moment."
Arlen took out a paper and pen and began to write.
Strictly speaking, Infinite Demonic Power was originally Grayfia's potential skill, awakened by the contract.
Since Grayfia was his Servant, the skill also manifested on him via the feedback loop.
A moment later.
Arlen stopped writing and handed the paper over.
Subconsciously taking it, Grayfia lowered her head and read.
[Grayfia Lucifuge]
[Race: Devil]
[Master: Arlen Lucifuge]
[Level: LV63]
[Skill: Infinite Demonic Power]
[Infinite Demonic Power: Demonic power is endless and inexhaustible. Any consumption of demonic power can be recovered in an instant.]
...
Looking at the text information, Grayfia's eyes went wide. "There is actually... such a skill?"
She looked at Arlen in disbelief, her eyes filled with shock.
This was truly too astonishing.
Although her maximum demonic power hadn't changed much...
Relying on the Infinite Demonic Power skill, her effective combat strength had increased by leaps and bounds.
Most importantly...
Grayfia felt the state of her body.
It seemed that the limits she had reached years ago had completely vanished.
And all of this was entirely because of Arlen.
Thinking of this, Grayfia's expression turned solemn.
"Arlen, is there a limit to how many Servants you can take?"
Arlen shook his head. "No."
Compared to the Evil Pieces system...
This was his major advantage.
As long as the aptitude fit, he could have as many Servants as he wanted.
"If that is the case, you must keep this a secret."
Grayfia warned gravely. "At least until you are strong enough to ignore the rules, you absolutely cannot expose this."
Unlimited reincarnation of Devils.
Granting them new, rule-breaking powers.
If word got out, those old geezers in the Council would probably go mad with greed and fear.
