Linde watched her fleeing back and shook his head with a smile.
It was the first time he had seen Grayfia like this.
"But how should I improve my strength?"
Rubbing his chin, Linde fell into thought.
When it came to getting stronger, there were indeed many good things he could try.
But since it was a hodgepodge world, who knew if the plot had changed?
"Speaking of which, do I really not have a cheat ability?"
The moment his voice fell, Linde heard only a 'ding'.
Then, a translucent virtual panel slowly appeared.
[Linde Lucifer]
[Race: Progenitor Demon]
[Level: LV30]
[Authority: Progenitor Demon Transformation]
[skill: Demon Contract, Demon Summoning.]
"This system panel is really simple," Linde grumbled, yet he stared intently at the text information above.
The next moment, some content naturally surfaced in his mind.
Demon Contract was a method of acquiring Retainers/Subordinates, similar in effect to the devil chess pieces of the Underworld.
However, the difference was that Demon Contract could not only reincarnate any race into a devil but also grant them a leveling panel.
Moreover, depending on the Retainer/Subordinate's aptitude, they might gain special skills.
And he could improve his strength through leveling up by fighting monsters and through the power feedback from his Retainers/Subordinates.
Demon Summoning, on the other hand, allowed him to issue contracts to all the worlds.
As long as someone summoned him, Linde could cross worlds.
As for Progenitor Demon Transformation, it was a transformation technique, briefly unleashing a portion of the power within his bloodline.
Besides that, even without completing the Progenitor Demon Transformation, his bodily fluids were treasures for devils.
In a cultivation world, he would be a supreme cultivation cauldron.
At this moment, Linde's expression hardened.
It seemed he would have to be careful in the future.
He didn't want to be imprisoned and played with by certain women.
"But being able to increase my strength by taking Retainers/Subordinates is really good."
Linde rubbed his chin, a glint flashing in his eyes.
"The only problem is that my Retainers/Subordinates all need some aptitude."
"Otherwise, they won't be able to withstand the transformation of the Demon Contract."
Thinking of this, Linde's eyes lit up.
He seemed to have a perfect target... "Sister Fia, become my Retainer/Subordinate."
Grayfia silently looked at Linde, who had come to find her.
His directness was a bit much to handle.
She smiled helplessly, "Little Linde, I don't mind becoming your Retainer/Subordinate."
"But the devil chess pieces I applied for you haven't arrived yet, you'll have to wait."
"I don't need devil chess pieces. Sister Fia just needs to agree."
Grayfia blinked, looking a bit confused.
Linde looked at the Demon Contract skill flashing on the system panel.
This was also a passive effect of this skill.
It could sense people who had the aptitude to become a Retainer/Subordinate.
As he expected, Grayfia completely fit the criteria.
"Are you sure you're not joking?"
Grayfia came back to her senses and subconsciously said, "Have you developed other reincarnation techniques?"
Linde shook his head, "It should be considered an awakening of some kind of ability."
Grayfia showed a look of understanding.
The devils of the Underworld were diverse.
Many possessed special magic and even power.
However, an effect similar to devil chess pieces was something she had never heard of before.
"Alright, I agree."
Grayfia asked curiously, "How do you plan to do it?"
"First, take off your outer clothing."
Seeing Grayfia's face begin to flush, Linde quickly added,
"I need to use my blood to engrave the Demon Contract, and your outer clothing is a bit in the way."
Honestly, he also found the process a bit abstract.
But on second thought, teasing his future Retainer/Subordinate seemed quite enjoyable.
"Okay."
Grayfia took a deep breath, her fingers trembling slightly, but she didn't hesitate, slowly unbuttoning her clothes.
Linde watched Grayfia, who was holding her clothes and whose ears were flushed, and his heart began to beat faster.
If it weren't for the ritual, he probably wouldn't have been able to hold back.
"Sister Fia, I'm starting."
Linde took a few steps forward, raised his index finger, and a trace of pale golden blood seeped out.
Seeing this, he was surprised.
It seemed that after awakening, his own body had already changed.
Even his blood was different.
Thinking this, Linde's movements didn't stop, and he directly pressed his bloody finger onto her smooth skin.
The moment the blood touched her, it emitted a faint glow.
The brilliant golden light quickly outlined a heart-shaped pattern on her skin.
Innumerable mysterious characters flashed and disappeared within the light.
Grayfia felt as if she heard a shattering sound emerge within her body.
The world, in her eyes, had changed.
It was as if the confinement of her body had completely vanished.
At the same time!
Linde only felt that the moment Grayfia became his Retainer, his physical fitness and magic power began to skyrocket.
The power he had just gained after becoming an Upper-level Demon was continuously breaking through.
Seeing that Grayfia's Reincarnation Ritual had not yet ended, Linde opened his panel.
[Linde Lucifergus]
[Race: Progenitor Demon]
[Level: LV51]
[Authority: Progenitor Demon Transformation]
[Retainer/Subordinate: Grayfia]
[skills: Demon Contract, Demon Summoning, Infinite Magic Power.]
...
Looking at the text information, Linde's pupils constricted deeply.
Good heavens.
It increased so much?
It seems it should be related to Grayfia's strength.
Subsequently!
Linde looked at the skill Infinite Magic Power.
[Infinite Magic Power: Magic power is endless, any magic power consumption can be restored in an instant.]
Linde looked at the skill description, his eyes lighting up slightly.
This skill.
It could not be said to be anything but powerful.
From then on, he would no longer worry about long-term battles.
"Little Linde... are you a Demon Lord?"
On the other side, Grayfia, who had just finished the Reincarnation Ritual, was already dumbfounded.
What's going on?
Linde, who was just an Upper-level Demon, had his magic power break through to Demon Lord Rank.
Isn't this too exaggerated?
"This is also my ability."
Linde explained, "And you also have new skills now."
"What do you mean?"
"Wait for me."
Linde took out paper and pen and began to write.
Strictly speaking, Infinite Magic Power was Grayfia's skill.
As Grayfia was his Retainer/Subordinate, her skill was also reflected in him.
A moment later.
Linde stopped writing and handed over the paper.
Subconsciously taking it, Grayfia lowered her head and began to read.
Linde opened his panel.
[Grayfia lucifugus]
[Race: Demon]
[Master: Linde Lucifergus]
[Level: LV63]
[skill: Infinite Magic Power.]
[Infinite Magic Power: Magic power is endless, any magic power consumption can be restored in an instant.]
...
Looking at the text information, Grayfia's eyes widened: "There's actually such a skill?"
She looked at Linde in disbelief, her eyes filled with pleasant surprise.
This was truly astonishing.
Although her magic power hadn't changed much.
But with the skill of Infinite Magic Power, the increase in strength was not just a little bit.
Most importantly... Grayfia felt her physical condition.
It seemed that the so-called bottleneck had completely disappeared.
And all of this was because of Linde.
Thinking of this.
Grayfia's expression became solemn.
"Little Linde, is there a limit to how many Retainers you can take?"
Linde shook his head: "No."
Compared to the devil chess piece.
This was also one of his great advantages.
As long as the aptitude was suitable, he could have as many Retainers as he wanted.
"If that's the case, you must keep it a secret."
Grayfia solemnly warned: "At least until you are strong enough, you must not expose it."
Unlimited Reincarnation Ritual of demons.
And even the ability to bestow them with new power.
If word got out, those old fogeys would probably go mad.
