My Power is Upgrading Everything (Rewrite)

--- Chapter 126 ---

With a plan ready and a quest going, Huo Yuhao contacted Qianye Ying'er through his watch. It's somewhat surprising because the satellite signal could penetrate the difference between the space realm.

Remember, Huo Yuhao is still in the Underworld.

Huo Yuhao had already guessed how this could happen after a brief assumption. Since the world of Highschool DxD has started to adapt to Douluo Dalu's Spirit Energy, this new source of power quickly traveled through space & time and spread across entire realms.

Allowing IOFI, or Interstellar Orbital Facility Item scan more than RISU could do in the Douluo Planet's orbit.

Huo Yuhao currently waited for Grayfia and others on the edge of the floating island. He dialed a contact in his watch and heard a low-ringed ringtone echoing.

"Hello~?" A familiar voice appeared.

Huo Yuhao smiled and replied, "Hello, mom."

"How are you?"

"Oh my... Someone finally remembered his mother. How cruel of you to only call me now, Hao'er! Hmph!" Huo Yun'er pouted on the other side of the call. She's watching over her student, who seems absorbed in their literature material.

"W-Well, I was quite busy." Huo Yuhao laughed nervously. Even though he knew this wouldn't work for Huo Yun'er, he still tried to make an excuse because he was "honestly." focused on too many things.

Of course, Huo Yun'er rolled her eyes when hearing the excuse.

'How adorable.' She thought to herself. It's like a child lying with all the evidence lying around on the ground.

'Hao'er become more playful lately, huh? It's a good thing because he finally could relax for a bit. Our world is too messed up and mentally consuming, especially for him.' Huo Yun'er recalled her son's repetitive all-nighters throughout the month.

When Huo Yuhao received his mission to conquer this world, he trained in the Advalon without a blink of sleep. If Huo Yuhao is exhausted, he will meditate and adapt first to his condition. Pushing his limit is borderline self-torturing.

His training cannot be replicated, even for Scathach.

"Hmm, Mom will trust you for now." Huo Yun'er smiled a little.

"Come visit Tokyo soon. I have prepared some gifts for you."

"They are ripe, thick, and juicy~!"

"There is also a fresh and young one here~!!"

Huo Yuhao was speechless when hearing Huo Yun'er reply. She was not talking about food, so it must be women she approved there.

He isn't dense enough not to know Huo Yun'er way of thinking. Still, This mother with a severe son complex is wild because she likely conquered Kyoto or the whole Youkai Faction by merely revealing her goddess-like presence.

'Oh god, I hope she doesn't do anything evil there.' Huo Yuhao hoped while releasing a sigh.

"Thanks, mom."

"I'll be looking for your gift later."

"Love you." He lastly said.

Huo Yun'er smiled and replied, "Love you too~!"

"And see you soon~!!"

At Kyoto, Huo Yun'er hummed happily because the beloved Hao'er finally called her. She looked down on the teaching class and saw several ladies or girls with beautiful appearances. They are in the top 1% of this country and possess enough raw potential to be valuable.

"Girls, what's our motto?" She called them out.

"Young master Huo Yuhao is number one." They responded immediately in harmony.

"People who offend him are trash. Minuscule dust in this vast universe."

"Serving him is the noblest duty, public or private."

A scroll hung on a tall pole rolled down and revealed Huo Yuhao's portrait of when he was reaching 12 years old. He's wearing a lazy hakama with his blue hair let down. His blue eyes are clear and steady, perfecting the handsome face blessed upon him.

"Praise, Young master Yuhao~!!" A shout ignited the spirit in the room.

It was coming from a girl.

She is a beautiful young woman with black hair and violet eyes with a ribbon on the right side of her hair, wearing an unorthodox Miko(Shrine Maiden) outfit consisting of a plain white robe, a red skirt, and black stockings.

This girl is Amaterasu, or what people throughout history have known as the Goddess of the Sun. The former leader of the Shinto Faction, who sealed herself inside a cave for several hundred years.

Only Yasaka and her siblings knew this cave until Huo Yun'er teleported inside it, forcing the Goddess to uncover herself.

And the Divine Foxy Mother dragged her out and began spreading the supreme son complex holy writing to Japan in just a few weeks. It's gaining popularity because this genre is quite rare in this era.

And single ladies or even married ones had been corrupted by the cultured book at an alarming rate, making global warming look pathetic.

The holy "It is wrong for a mother to love her son passionately." and "100 ways to win your son's heart." have become best-sellers, causing a wave in the light novel industry. Even though slower, these books have started to reach other countries.

The author EAY is a genius with a mysterious identity, and only some people know her personally.

'Fufu~! SPREAD DA CULTURE~!! MUAHAHAHA~!!!' A burst of laughter echoed in Huo Yun'er mind. This voice is somewhat similar to Huo Yun'er herself but less motherly and more experienced in certain aspects.

A pink-haired woman floated within Huo Yun'er spiritual sea. She's Huo Yun'er mentor and legacy master, Yae.

Yae formed a contract to possess the inheritor's body once in a while until Huo Yun'er created a new body for her. In the meantime, she wrote her light novels and reversed her name for the pen name.

Huo Yun'er shook her head because this deity teacher of hers had a few screws loose. 'Just like me, what's wrong with it? Immorality is hot!' She thought while closing her eyes.

'Nothing is forbidden if you're brave enough~!!'

Huo Yun'er breathed in and said, "Come here soon, Hao'er."

...

...

Back to Huo Yuhao, everyone has prepared for Familiar Forest's the exploration and Astarorth Clan's cleaning.

Coincidentally, Koneko said that her peerage master(Rias Gremory) and Sona Sitri planned to visit the Familiar Forest. They have scheduled to do this since Rias reincarnated Issei Hyoudou into a devil.

"I hope your dumb master doesn't do anything idiotic there." Huo Yuhao couldn't help but comment. After seeing Rias and witnessing her inability to control the peerage despite being a high-ranked young devil, he was disappointed.

The red-headed dummy literally let her knight fight someone stronger by a mile away. She could have told him to retreat and solidify their defense formation first. Having an emotional subordinate sure is hard, but if this was her limit of authority. Then her peerage is doomed.

'Just how many plots helped Rias and Issei survive this world?' Huo Yuhao was dumbfounded.

"Then, I'll be going." Huo Yuhao flapped his devil wings.

"Have a safe trip, Devil God/Lord Yuhao." Venelana and Misla lowered their heads slightly. They somehow look like a long-lost twin with brown hair and purple eyes.

"Mm, I'll be waiting here too." Ingvild waved her hand at Huo Yuhao.

Huo Yuhao smiled at them slightly and looked at the people who would accompany him to the Familiar Forest. Serafall and Koneko joined this trip because Rias and Sona might come in contact with Rizevim later.

As for Kuroka and Ophis, they are doing this for fun.

"Well, let's go!"

Huo Yuhao loosened himself and vanished from everyone's eyes, flying to the horizon with the speed of sound. A sonic boom echoed several kilometers away from them.

Grayfia summoned her handgun and shot herself with an accelerating bullet, which increased her speed by a lot. She also disappeared from her position and followed Huo Yuhao from behind.

Meanwhile, Ophis yawned and kicked the air, teleporting herself to Huo Yuhao's side.

"Boo~! What a show-off!" Kuroka complained while puffing her cheeks because there was no way she could follow them with her physical ability alone. Kuroka might be fast but compared to a monster like Grayfia and Ophis. She is nothing.

It also applies to Serafall and Koneko.

"Damn..." Serafall commented with a weak smile. She knew Huo Yuhao could awaken one's martial soul, but to think Grayfia would grow to this level was astonishing. It's not even two months since Huo Yuhao reappeared back in this world.

'Yuhao Onii-sama is amazing~!' Koneko's eyes brightened when seeing this scenery. She clenched her tiny hand and vowed to become stronger soon, like what the saintess taught her.

Serafall shook her head and said, "Let's just use the teleportation magic."

"Flying there will be a hassle."

"True..." The Nekoshou sisters agreed with Serafall.

Huo Yuhao breathed in and felt the air around him, smiling because Spirit Energy's concentration had become thicker. He activated his Observation Haki and scanned the area he passed through.

'Evo, how many Upgrading Tickets do I have currently?'

[Upgrading Tickets: Silver(44), Gold(1), Black Gold(1), Platinum(1)] Evo showed him the system panel.

There are still a few kilometers away from the Familiar Forest, according to Grayfia's map. He has enough time to upgrade something to satisfy his boredom. Also, He gained some Silver Upgrading Tickets from the side mission.

Huo Yuhao remembered he got Martial Technique Lucky Spin from killing Devil King's descendant quest. And he was annoyed.

"Fuck, it's gacha again."

"Even with my luck and skill, I'm still not confident with it..."

[Do you want to use Martial Technique Lucky Spin?]

"Ugh, do it." Huo Yuhao sighed in defeat.

[High Roller activated]

[Spin...]

Huo Yuhao looked at the spinning circle before him and at least hoped for a good martial technique. Even if he got a bad one, he could upgrade it in the future, but let's not get his hopes down first.

[Ding!]

"This..." Huo Yuhao's eyes widened in surprise.

[You have obtained "Gathering of Ten Thousand Waves." Technique]
