My Power is Upgrading Everything (Rewrite)

--- Chapter 95 ---

A few hours after Huo Yuhao picked cats from the park, he played around with them on the terrace. Since they are in their cats' forms, he doesn't have to worry about getting caught red-handed by someone. They are just adorable creatures, that's it. Yep, Definitely.

Well, Kuroka and Koneko look somewhat scared of him.

"I won't hurt you guys." Huo Yuhao sighed in defeat.

Kuroka, in her cat form, nervously looked at Huo Yuhao and replied, "B-But you caught us, Nyaa..."

"U-Un." Koneko nodded her head a little, hiding behind Kuroka. Despite her awkward relationship with her older sister, she couldn't help but rely on Kuroka's protection. And even knowing the older Nekoshou wouldn't be able to do anything before Huo Yuhao.

"That's true. Only for a few days, though." He returned to them. "I bring you two here to experiment on something."

And upon hearing Huo Yuhao's comments, Nekoshou's sisters started to tremble in fear because of the word "experiment." which struck anxiety in their hearts, especially Koneko. Of course, Huo Yuhao realized his accidentally specific phrasing late and facepalmed himself.

"My bad..." He sighed while patting the cats with a soothing aura from Wood Fairy's innate ability. He watched their ears and tails slowly drop down in comfort.

"I bring you two here to learn more about Senjutsu and Youjutsu. Oh yeah, also their branches of usage like Touki."

Kuroka calmed down and asked, "Are you also a Yokai?"

"Nope." Huo Yuhao answered with a light chuckle, which left the black cat quiet for a moment. "Regardless, don't worry. It's not hard for me to discover a way to learn it. Just give me a few drops of your blood."

"Swear." The black cat stared at Huo Yuhao solemnly.

"Hmm??" He was confused by her sudden request.

"Swear that you won't hurt Shirone first." Her hazel-gold eyes shone with a resolution, which caused Koneko to be stunned.

Koneko looked at her older sister and touched her traumatized spot because she pushed herself this far to protect her. And this is definitely not something Stray Devil, who becomes power-hungry after killing her master, could do.

'Onee...' The white cat looked down and found Kuroka's legs shivering while making this deal. Unknown to Koneko, she started crying when learning that her older sister protected her from evil people years ago when they ran from Naberius Laboratory.

'Kuroka-nee doesn't discard me. She put herself in danger to save me from other devils' hands.' Koneko isn't dumb. It wasn't difficult for her to put the pieces together, but she was too afraid to admit her past.

Huo Yuhao smiled and responded, "I won't hurt her, I promise."

Kuroka stepped forward and offered her hand to let Huo Yuhao absorb the Nekoshou Blood. He shook his head and transformed his left hand into War Beast's form, gently sticking his sharp finger into Kuroka's small cat leg.

She hissed for a moment and suddenly moaned, "MMhn~! NYAA!!"

"T-This feeling, so good~!"

A joyful purr came from Kuroka's mouth, which left Huo Yuhao speechless inside because the suction force shouldn't make her feel anything. Is this Kuroka's coping mechanism to prevent her from getting nervous? It Sounded lewd for some reason.

[You have obtained Nekoshou Bloodline]

[Name: Nekoshou's Bloodline]

[Type: Yokai's Blood]

[Grade: SS]

[Description: Nekoshou is a special Nekomata or Cat Yokai, they only had female members and bred other races, usually conducted with male humans or other more powerful races. Nekoshou have a high talent in Spiritual Energy, Nature Energy, and Supranatural Techniques such as Senjutsu and Youjutsu]

[Ding! Nekoshou's Bloodline is 100% compatible with Great White Tiger's race]

[Do you want to absorb all positive traits?]

"Hmm, is there a negative trait?" Huo Yuhao couldn't help but question his system, leaving the black cat lying lazily on the floor with a blissful look.

[Nekoshou has an uncontrollable urge to Mate with strong partners. Even though Great White Tiger will absorb it just fine, your libido potentially grows beyond your sanity and control] Evo answered with a dull tone.

[Unless you wanted to become a Wild Animal who couldn't think straight all of the time, I advised you only absorb Nekoshou's positive traits]

Huo Yuhao was speechless and muttered, "Ugh... I don't want to become horny all the time."

[You have absorbed Nekoshou's Bloodline]

A weird twinkle spread all over Huo Yuhao's body, and adorable tiger-like ears appeared on top of his head. It was a pair of white-furred ears with a black-striped pattern. Three tails with a similar stripe also come from his upper butt, swinging around playfully.

"Nyaa?" Kuroka and Koneko's eyes widened when seeing this. They could feel an overwhelming Natural Energy from Huo Yuhao's body, wondering how he could achieve this.

Huo Yuhao brushed over his new ears and asked, "What do you think?"

"Y-You look handsome, I mean adorable, I mean handsome... Ugh, it's confusing." Kuroka released a frustrated noise while walking around Huo Yuhao with a curious gaze. Koneko doesn't know why, but she agrees with her sister's statement. Nekoshou's sister looked at Huo Yuhao's eyes and noticed his royal blue eyes had gained a gold hue, similar to theirs.

"Is that so?" He laughed while patting them again.

"Then, let's start the test. I want to learn all kinds of abilities related to Nekoshou. Can you teach me?"

"I'll compensate you two later."

"Okay, Nyaa~!!" Kuroka and Koneko stared at each other and nodded simultaneously. Even though Huo Yuhao hasn't tried to tame them, he indirectly has gained favorable impressions. Of course, the sisters still need time to accept their situations.

Huo Yuhao created a time chamber with Primordial Runes and expanded the room to accommodate the training. He wants to experiment with many things, including a quick yet synergized way to combine Senjutsu and Youjutsu with his overall arsenal. Since he has watched quite a lot of anime and possesses enough experience in energy manipulation, he might be able to recreate some techniques. There is also Eluxia, who could give me insight later.

"Um, before we start, I had to notify Rias Buchou first. So she doesn't have to worry about me." Koneko suddenly said, which caused the older Nekoshou to frown inside.

Even though Kuroka has a contract with Sirzechs Lucifer to let Koneko live peacefully, she still doesn't trust the redhead devil because the condition of the Underworld is so corrupt. Not to mention she actually was still considered an SS-Ranked Criminal there.

'The contract is not working very well. What could guarantee me that Shirone wouldn't be caught in this kind of situation again?' The black cat thought while looking at Huo Yuhao. A brilliant idea flashed in her mind because Blue-Eyed Dragon God is one of the strongest beings in this world.

"Nyahahahaha~!" Kuroka mischievously giggled.

Huo Yuhao ignored Kuroka and stared at the small white cat, "Oh, about that. I have already informed your peerage about this meeting through Murong Qianxue."

"Eh, but doesn't she..." Koneko remembered the cold-looking woman.

"She won't kill them, right?"

Looking at Koneko's worried expression, Huo Yuhao assures the white cat with a promise that the Ice Demoness wouldn't kill anyone without his permission.

"Even though Murong Qianxue appears cold, she's gentle inside. And she never fights my order." He said, which caused Koneko to sigh in relief.

"Anyway, let's start."

Time Chamber's Array is a technique that only Scathach and Huo Yuhao could perform because no one else has enough mastery over Primordial Runes to create such a thing. It separates a marked dimension like Mirror Dimension but also alters the time flow to be slower than real-time. With trial and error for the past six years, Huo Yuhao can only create a small room with a 1:24 time dilation, meaning one day inside equals one hour outside. It's also energy-consuming, and he couldn't maintain it for more than a week.

Well, he has a cheat to maintain it forever.

[You have applied Power of Infinity on Time Chamber Array] Evo notified with a monotonous voice.

[You have created a small pocket dimension]

--- 7 Days Later ---

Two extremely sweaty cat girls rested on the floor with exhausted looks. They had been through hell and experienced so many bizarre things in just a week. And from time to time, they even questioned their sanity.

First of all, Huo Yuhao is a complete monster.

Even though Kuroka could be considered a rare genius and developed her mastery over Senjutsu, Touki, Youjutsu, and Magic at a young age, she still couldn't be compared to Huo Yuhao. This guy absorbed everything like a sponge and developed a new system of Youjutsu. He also created an efficient way to use Senjutsu and Touki, applying them to his surroundings and himself.

No, in the first place, the Magic System in the High School DxD's world is always looser than another universe. Even a dumb person could become a powerhouse with enough innate talent and imagination. And Devils with strong Demonic Power and creativity are wasting their potential on trivial things like Clan's ability. Of course, there are a bunch of magic types in this world, but Huo Yuhao couldn't help but discover many loopholes.

As far as Huo Yuhao has seen, only Ajuka Beelzebub, Serafall Leviathan, Grayfia Lucifuge, and Sirzech Lucifer met the criteria to become a genuine magician from the devil's side. How disappointing, and that's because the Original Satan manipulated their Demonic Energy more roughly than them.

Like Eluxia commented when seeing Raynare manipulating her Light Elements and Holy Energy. "They are too crude."

[Solomon's Blessing was in effect]

[You have formed 1st Class Magic Circle]

[1st Class Magic Circle has advanced to 2nd Class]

[...]

[...]

[...]

[You have reached 6th Class Magic Circle]

Huo Yuhao breathed in and let a bright white magic circle with unknown characters surround his Blood Core, which was the source of his demonic energy.

"How strong..." Kuroka solemnly commented while feeling an immense aura from Huo Yuhao's body. Unlike other Devils, his demonic energy is oddly warm and gentler.

"I could reach a higher stage, but that would be a waste of time. The 6th Class Magic Circle is enough to strengthen any magic I invented to Satan Class Level." Huo Yuhao opened his eyes.

He yawned and added, "Well, Next."

An enormous amount of Natural Energy entered Huo Yuhao's body and circulated through his bloodstream. He breathed out and meditated in the lotus position until the nature traits merged with his Spirit Energy, turning him into a Sage. Beast Sage, to be exact.

"Hmm, not bad." Huo Yuhao's silky blue hair becomes mostly white but different from his War Beast's form. There is a shade of red on his hair.

[You have mastered Senjutsu and Touki]

[You have attained Chaotic Beast Sage Mode]

"Amazing..." Koneko mumbled while clenching her small hands because she wanted strength like this. With this fearsome force, she doesn't have to worry about getting protected by her loved ones. She could stand in the world proudly without fear.

Huo Yuhao flicked Koneko's forehead and made her whimper in pain for a second. "Accept your origin and train everything you had to a significant level. When you reach it, I'll teach you how to accomplish this form." He said with a smile.

"R-Really, Nyaa?" A strong glimmer of hope appeared in Koneko's gold cat eyes.

He patted her and replied, "Yeah."

"Now let's get out of this place first-!"

BOOM!

"HUO... YUHAO~!!!" An excited female shout comes from a hole. The Time Chamber Array "abruptly." was destroyed by the owner of this voice, and Huo Yuhao laughed weakly because only one person could do this so effortlessly.

Kuroka covered her face with her kimono's sleeve and saw a beautiful young woman with long purple hair, red eyes, and a chest slightly more voluptuous than hers casually stepping into the room.

"Who?" She whispered out of surprise.

"What a warm greeting... Welcome back, Shishou." Huo Yuhao smiled at Scathach.

Scathach giggled and immediately hugged Huo Yuhao, taking over his pale lips. And her slick tongue probed him wildly. She single-handedly made several girls and women jealous on the spot.

"Ahh... It's the best~!" She breathed heavily near Huo Yuhao's ears.

"Fresh Yuhaonium."

Koneko blushed and covered her young eyes with her hands, which was a useless attempt because she peeked into the scenery through the gaps of her fingers anyway.

"What a perverted thing to do..." She said to herself.

"I-I wonder how it feels."
