Chapter 5: The Promise Between the Two!

Chapter 5: The Promise Between the Two!

"Of course, if I haven't grown to the level of an Ultimate-Class Devil after all this time, the Devil King's blood within me would be crying," said Vitan matter-of-factly, without a hint of arrogance on his face.

The Ultimate-Class Devil!

This rank is considered an absolute core force among the demon community, barely qualifying as the decision-making level of demonkind.

For ordinary demons, it is a level unattainable even after a lifetime of effort.

But for one carrying the direct bloodline of a Devil King like himself, it is merely an inevitable process of growth.

Even if he wasted time and didn't cultivate himself, he could naturally grow to this level in just a hundred years.

This is the unreasonable advantage brought by bloodlines.

An unbridgeable chasm that no commoner could overcome through hard work alone.

"Indeed, you still need to put in more effort," Grayfia nodded with the same attitude.

Although she expressed her appreciation for Vitan's growth rate, she didn't want her praise to make him complacent and stop his progress.

A measured criticism was still necessary.

"I know!" Vitan accepted Grayfia's admonition without dissatisfaction.

After all, this existence akin to an elder sister had reached the Ultimate-Class Devil level by the age of thirty without any Devil King or one of the seventy-two pure-blooded demon bloodlines.

"By the way, sister, are you really not going to try the magic system of my grimoire? If you want, I can have Radicles make a handwritten copy for you," said Vitan.

Radicles Astil was actually the original grimoire from the anime world of the "Seven Mages." It was the handwritten copy of the main character Astil's grimoire, as well as the grimoire used by the previous Devil King, Deus Trinity Demon Lord.

Recording all the knowledge of other worlds, it integrated the "Seven Deadly Sins" libraries of "Pride," "Envy," "Wrath," "Sloth," "Greed," "Gluttony," and "Lust" into one omniscient and omnipotent legendary grimoire.

After the previous Devil King Deus indulged his subordinates and allowed his own self-destruction, it carried the Devil King's true core across countless parallel worlds until finally arriving in this world and choosing Vitan as its new master.

"No need, you said that if you made a handwritten copy now, your grimoire would inevitably fall into a period of weakness!" 

"At present, your own growth rate should be the top priority." 

Grayfia waved her small hand, rejecting the offer directly.

Those strange methods, weapons that could transform into human form, all piqued her interest in her brother's grimoire.

But if that came at the cost of temporarily slowing his growth rate, she would never agree.

"Ah—!" 

What Grayfia said was true.

If not for the longing expression she had shown, he would never have made such a decision.

Aquila had proposed exchanging equal value techniques for a handwritten copy countless times, but he had never agreed.

"However, in exchange, I'll hold onto this for now." 

Before Vitan could finish his contemplation, he saw Grayfia extend her two jade-like fingers to grasp the mutated demon chess piece representing the Queen from his demon chess set.

"Hm?" 

Inevitably, Vitan let out a questioning sound.

"Don't tell me, sister, you have a suitable Queen candidate for me?" 

Grayfia's hand holding the chess piece paused, a faint blush flashing across her exquisite face, though too fleeting for Vitan to notice as her expression remained coldly elegant.

"You don't need to ask too much about this!" Grayfia said coldly without expression. "I will find you a suitable Queen candidate later." 

"Okay, okay! As you wish." Vitan immediately surrendered, not probing further into the matter. 

The first reason was that he had developed this habit since childhood - whenever Grayfia showed this expression, it meant her decision was not something he could question.

The second was that he believed Grayfia would never wrong him. Since she had taken action, she would definitely find him a Queen who satisfied him in every aspect.

"Mm!" Grayfia nodded in satisfaction and put the chess piece symbolizing the Queen into her pocket. 

"But sister, why are you so concerned about my strength?" 

"I think my growth rate over these years has been decent, but you always seem so impatient." 

After another brief silence, Vitan raised the question in his mind.

Grayfia's urgency was visible to the naked eye.

It was precisely because of this that he had received so much of Grayfia's Spartan-style education since childhood.

However, he had no aversion to such education.

As someone who had transmigrated from a world without any mystical realms and suddenly arrived in this world he had longed for, he naturally developed an immense enthusiasm for cultivating supernatural powers, even though his starting point was not the typical cliche of a loser's reversal.

Endowed with top-tier resources, he was bound to be highly motivated to train in such abilities.

Ultimately, however, he still harbored doubts about Grayfia's sense of urgency.

After all, given his status, the level of his strength was not that important.

His very identity already placed him at the absolute pinnacle of the demonic hierarchy.

Even if he were a waste, no demon would dare look down upon him.

Just like those pure-blooded elders - those old men trading on their age might only possess the strength of a High-Class Devil, yet even the Devil Kings dared not easily deny their existence.

In the Demon Council, they were one of the major forces opposing the Four Great Devil Kings.

"About this, you don't need to ask any further." 

"This is the promise between me and the First Asmodeus. Just listen to me and strive to improve yourself." 

Grayfia's tone softened as she was well aware that due to her insistence, Vitan, despite being the heir to a supreme power, had not enjoyed the life befitting such an heir during his childhood.

At an age when he should have been indulging in youthful pursuits, all he did was cultivate.

While other young demons were already wallowing in carnal desires and sensual pleasures, savoring the colorful experiences of life.

"Such an old cliché again. At least give me a goal, sister." 

"What level exactly do you expect me to reach?" 

Vitan spread his hands in resignation, having heard such profound words to the point his ears were nearly calloused from listening to them.

Grayfia sighed, her clear pupils gazing at Vitan as she slowly parted her red lips.

"The Devil King level. On the day you reach the Devil King level, I will tell you the entire promise between your grandfather and me."
