1: Chapter 1

?

Article 1: When living together, it is forbidden to enter the other party's room at will; a distance must be maintained.

Article 2: It is forbidden to let anyone know that we have signed an agreement.

Article 6: During the period of cohabitation, it is forbidden to...

Article 13: After the male party graduates, he must take the initiative to annul the engagement.

Luo Yu stared at the densely written agreement, completely bewildered.

He had been single until death in his past life. After finally transmigrating and being reborn, he actually got a fiancée for free?

Although this fiancée was eager to distance herself from him, she was still a fiancée, after all.

"Sign the document, and I will give you every single cent of the money I promised earlier. If you have any other requests, feel free to bring them up, as long as I can fulfill them."

Sona saw that Luo Yu hadn't spoken for a long time, and she frowned.

If he didn't agree, the family engagement couldn't be annulled. The key issue was that the other party was just an ordinary person, so she couldn't use a Rating Game to annul the engagement.

If it were any other pure-blooded devil, they would have already revealed their identity and threatened him.

But the education she had received since childhood, along with the constraints of the contract, did not allow her to do such an unscrupulous thing.

This was already the best solution she could think of.

Besides, they had to live together for three years, otherwise, there would be a backlash.

"Sorry, I was thinking about something else just now. I'll sign the agreement."

Luo Yu looked up at Sona.

Compared to his impression of her, she was still very young and inexperienced right now.

After all, it was still three years before the plot began, and she had just entered Kuoh Academy.

Luo Yu picked up a pen from the table and readily signed his name on the agreement.

Anyway, it made no difference whether he agreed or not.

"Tomorrow, I will send someone to pick you up and help you move your luggage."

Sona picked up the agreement and checked it once; satisfied that there were no issues, she finally breathed a sigh of relief.

"No need for the trouble. Just give me the address, and I can go there myself."

"Alright then, I'll wait for you at home tomorrow."

Sona Sitri didn't stay long at Luo Yu's house; she left right after saying that.

Only Luo Yu remained in the living room.

Suddenly, a cluster of emerald green light emerged from his left hand.

A low and majestic voice came from the light.

"Brother, your luck is really not bad. If I'm not mistaken, that girl is a devil, right? The pure-blooded kind."

Luo Yu pressed his temples and added, "She is Sona Sitri, the next head of the Sitri Clan, and the younger sister of the current Maou, Serafall Leviathan."

"A Maou's sister... that's not good news."

"Ddraig, aren't devils supposed to be quite treacherous? Being this trustworthy is actually unlike their style."

"Partner, you have a stereotype about devils. Most pure-blooded devils place great importance on their reputation."

Luo Yu was speechless.

Could it be that all the devils he had cut down previously were just the scum among devils?

"Besides, it's mainly because your ancestor signed some kind of contract with the Sitri Clan, so they have to honor it. The Great War has been over for so long; without that binding them, who would bother with an ordinary person?"

That was probably it.

Otherwise, why would the dignified heir of House Sitri marry a human?

"Were there humans participating in The Great War back then? Ddraig, weren't you there too? Although you were just adding to the chaos."

Luo Yu looked down at his left hand—where the Sacred Gear "Boosted Gear" resided.

"I was so focused on fighting that guy in white that I had no time to look at anyone else. Besides, with Maous, Gods, and the Governor of the Fallen Angels all present, the presence of a single human was simply negligible."

Luo Yu felt that made sense.

The true main forces of The Great War were the devils, angels, and Fallen Angels. Humans, yokai, and the like, even if they got involved, were just background characters.

Fiancée...

His mouth twitched involuntarily, revealing an undefinable smile.

This was the first time he had heard that he had a fiancée.

No—when his parents were still around, they used to tease him in a fairy-tale tone, saying that a beautiful fiancée would come to find him in the future.

They said that a thousand years ago, his ancestor helped a certain noble win The Great War and signed a contract with them.

Once that family gave birth to a daughter, she would marry his ancestor's descendant.

Although he was a child back then, he was precocious.

Nonsense, right?

A thousand years had passed, and his ancestors for eighteen generations had turned to dust; that family still hadn't produced a daughter? It was more likely that their entire family line had died out.

Even if this really happened, it was probably just a lie to swindle his ancestor.

But when Luo Yu opened the door and saw Sona, who claimed to be his "fiancée," he understood immediately.

Maybe that family really hadn't produced a daughter all this time.

The fertility rate of pure-blooded devils was frighteningly low.

Plus, the "The Great War" his parents spoke of—thinking about it now, wasn't it that very war?

His ancestor was likely a human who stood on the side of the devils.

The space on the second floor had been modified by magic.

The area had been expanded more than tenfold, nearly the size of a football field, and the ceiling had been raised by over a dozen meters.

Right in the center was drawn a huge magic circle, extremely complex in structure, blending traces of various systems such as Eastern sorcery, Nordic Arcane Magic, and Abyss magic, with dense runes overlapping each other.

Suspended above the magic circle was a fist-sized mass of blood, exuding terrifying pressure and a pure dragon aura.

That was the essence blood he had collected after defeating countless dragon species over these years.

Whenever those dragon species mentioned this generation's Red Dragon Emperor, they would grit their teeth in hatred.

Being pinned to the ground and beaten, then having their essence blood forcibly extracted, was simply the greatest humiliation of their lives.

"Ddraig, it's time to start."

Luo Yu lay flat in the center of the magic circle and called out to Ddraig.

Immediately after, a mass of crimson gauntlet wrapped around his left arm, with an emerald green gem embedded on the back of the hand, emitting a dazzling light.

This was the true form of the Boosted Gear, one of the thirteen Sacred Gears.

The dragon essence blood, pulled by the gauntlet, turned into thousands of blood threads as fine as cow hair, and followed the pores on Luo Yu's skin surface, frantically drilling into his body.

Pain.

Severe pain.

That bone-deep sense of torture was like someone holding a knife and cutting his flesh bit by bit, dismantling his cells.

The pain rushed straight to his brain, and even his soul trembled uncontrollably.

A transfer notification popped up on Luo Yu's phone earlier.

The massive sum of wealth Sona promised had arrived.

Following it were over a dozen zeros; an ordinary person wouldn't be able to earn that much in a few lifetimes, let alone dozens of lifetimes.

If this money were made public, he could easily squeeze into the top three of the world's richest list.

But for Luo Yu, worldly money was just a pile of waste paper, nothing more than a string of numbers on a phone.

"Ddraig... Dragon Reincarnation, it starts today."

Luo Yu casually tossed the phone aside, his tone exceptionally grave.

"Just because of this pure-blooded devil?"

Ddraig was somewhat puzzled.

It's not like no pure-blooded devils have died at their hands over the years; they just killed a descendant of a current Maou not long ago.

"That's only part of the reason. The technology for Dragon Reincarnation is inherently illegitimate, and the Underworld has already started to get suspicious. Finishing it early can also reduce some trouble."

Ddraig didn't say anything more.

The stored dragon essence blood was already sufficient; Dragon Reincarnation was just a matter of time.

Being cautious was never wrong.

The veins on his forehead bulged like earthworms, and his entire face was twisted beyond recognition. His fists were clenched tightly, his fingernails digging into his palms, and blood dripped down his fingers.

Luo Yu could only grit his teeth and endure, forcibly holding on through the modification of his body by the dragon essence blood.

If he couldn't pull through, all the suffering he had endured would be in vain, and he wouldn't even get anything out of it.

"Brother, you have to hold on..."

Ddraig, deep inside the Boosted Gear, broke into a cold sweat for him in his heart.

In Ddraig's view, Luo Yu as a host might not be the strongest fighter among the past hosts of the Boosted Gear, nor was he the one with the most dazzling talent.

But when it came to madness and guts, all the past hosts combined couldn't compare to him.

Luo Yu knew clearly in his heart that he couldn't compare to the host of that guy, the White Dragon Emperor—the guy had ancestral Maou bloodline. He also couldn't compare to the host of the True Longinus, who was a descendant of an ancient hero.

Even if his ancestors had been glorious back during The Great War, by now, that bit of glory had long since dissipated.

The bloodlines and foundations of the God and Devil races had never been comparable to humans since ancient times.

If he wanted to surpass Gods and Devils, he had to take another path.

The method Luo Yu came up with was something very special in High School DxD—reincarnation technology.

Discard this human body and reincarnate into a God or Devil race.

Since he was going to reincarnate, he had to choose the strongest race to target.

In High School DxD, the only ones qualified to be called the "strongest race" were dragons.

The Five Great Dragon Kings, the two Heavenly Dragons, the Evil Dragon that disrupted the Three Realms...

Which of them wasn't someone who could walk sideways? Not to mention the Infinite Dragon God Ophis, who occupied the world's number one spot from beginning to end, and Great Red.

Therefore, Luo Yu was daring enough to run right under the nose of the Devil Super Devil, Ajuka Beelzebub, steal the reincarnation technology, and spend several years tinkering with a unique set of Dragon Reincarnation.

To succeed, one had to sacrifice something first.

When Ajuka Beelzebub was developing devil reincarnation, he used countless living beings as stepping stones.

And this Dragon Reincarnation thing, which used dragon species essence blood, simply couldn't find other experimental subjects.

If it succeeded, he would take one step past the ceiling of this rotten human shell.

If it failed, he could only roll into the bottomless abyss.

The night had completely deepened, and moonlight was scattered all over the ground.

Luo Yu's Dragon Reincarnation was still continuing.

Time had already passed for six or seven hours.

Inside Luo Yu's body, those dragon species essence blood were rampaging like crazy.

The transformation process was non-stop; every muscle and every bone was being torn apart and recast. A layer of black, bloody fluid slowly seeped out of his pores, and that snow-white shirt had long lost its original color, soaked through with black blood and sticking to his skin.

The pain slammed into his nerves wave after wave.

On the surface of Luo Yu's skin, a thin layer of scale armor slowly emerged.

Ddraig recognized it at a glance; those were dragon scales.

This meant that the most difficult first stage of "Dragon Reincarnation" had been endured. The dragon species essence blood hadn't been able to destroy Luo Yu; instead, it was swallowed by him and became his own.

Ddraig did not hesitate and directly activated the second stage.

The magic circle beneath Luo Yu lit up, the silver light faint, spreading out like water.

The array acted like a catalyst, forcing the dragon species essence blood inside him to suddenly expand and explode. His entire body also swelled up, blood mist seeped out from his skin, wrapping him into a huge cocoon.

The surface of the large cocoon exuded an aura that made one's heart tighten, as if something terrifying was being gestated inside.

Ddraig finally breathed a sigh of relief.

Just as he had expected, Luo Yu had pulled through.

Next, all that remained was to wait—wait for him to break out of the cocoon.

Ddraig stared at the large cocoon, unable to help but feel expectant in his heart.

A human reincarnating into a dragon species—this was the first time.

What exactly was the difference between a dragon turned from a human and a naturally born dragon species? Where were they strong? Where were they weak?

Only when Luo Yu finished completely would he know.

The night grew deeper.
