A Demon King Through The Worlds

"I already have 100 BP so why am I still so weak?" complained Mitsuri, in a sly voice, acting like a spoiled child.

"No, you're very strong" replied Lucian, while staring at Mitsuri.

He had to admit that she looks pretty cute when she acts like that.

"But didn't you say that 1 BP is 200 kg of force?" Too bad Lucian's response only increased her doubts.

"A demon with 1 BP may have 200kg of strength, but that doesn't mean that each BP increases strength by 200kg. Humans have a 'maximum' vitality which, if quantified, would be 10 units.

Most humans would only have 8 units, teenagers and children having even less. These 10 units would allow the person to lift 200 kg with one hand.

Of course, this is nothing more than the maximum theoretically possible.

In the process of transforming into a demon, it can be said that vitality is maximized, and then converted into 1 unit of blood power.

So the first unit of blood power grants a strength of 200 kg, and the subsequent ones will probably grant an increase of only 20 kg" explained Lucian and she listened with a silly look on her face.

The face of someone who listened and didn't understand anything.

"So 100 BP is actually not much?" asked Mitsuri, Lucian's response only serving to increase his indignation.

"No way, in this world the maximum that can be obtained is 1000 BP, in addition to that 100 BP is already approximately equivalent to 2000 kg of force, or between 4000 and 5000 kg using both hands" replied Lucian, a touch of comfort in your words.

Not that this force was small, it is enough to break rocks with one punch.

"And you also have to remember that blood power not only increases strength, but also speed, regeneration and defense." Lucian concluded.

"At least that much," she said, before continuing: "Changing the subject, my parents agreed to go to another world with us. And they were also very happy when I told them that I found someone to marry."

"That is good." Lucian nodded.

This would save him a lot of trouble, the main one being preparing a space anchor so he could return.

He was currently in possession of three kekkijutsus of a spatial nature.

The [Demonic Gourd Magic], [Infinite Castle] that he copied from Nakime, and [Sash Manipulation] that he copied from Daki.

Yes, a few days ago he had copied Daki's kekkijutsu, specifically for the purpose of enhancing his space-related powers.

He intended to combine these powers in the future to form a stronger power.

And another curious fact is that he discovered the limit of kekkijutsus, which is one kekkijutsu for every 200 BP.

'That is, my current limit is 5 kekkijutsu.'

At this moment Mitsuri approached and sat on Lucian's lap.

Hugging his neck, she snuggled in and took a deep breath, smelling him.

And Lucian hugged her, stroking her head lightly with his right hand.

"That's another thing that's good," he said, squeezing her a little tighter.

"I agree with you" replied Mitsuri.

It might not be much, but simply holding each other warmed their hearts and calmed their minds.

After a while, Daki also approached, and seeing what was happening, she naturally wanted to get involved too.

"I want it too!" she exclaimed as she sat on Lucian's other leg.

Of course Lucian wouldn't refuse her, after all she was his wife.

Too bad Shinobu and Kie wouldn't show up. Shinobu was busy training to control the new strength she had gained and Kie was at her house taking care of her children.

'Should I spend more time with them?' Lucian questioned himself internally, even if he spent a certain amount of time with Tanjiro and the others, perhaps it wouldn't be enough.

'I think tomorrow I'll stay with them a little longer.'

Putting that aside, Lucian returned his focus to the beautiful women in his arms.

"Shall we go out for a walk?" He suggested.

"Good idea!" Both quickly agreed, their excitement visible, after all it would be more fun than staying in the monotonous infinite castle.

And if Lucian asked them out on a date, they would naturally accept happily.

"Where are we going?" Mitsuri asked excitedly, after jumping in anticipation.

"I think any random city will be sufficient." Lucian just shrugged, in his opinion the place didn't matter much.

"Then let's climb Mount Fuji!" Mitsuri suggested, giving the idea of climbing the highest mountain in Japan.

"No! Why would you want to climb a cold mountain? Let's go to Hokkaido and enjoy the hot springs!" Daki quickly denied Mitsuri's suggestion, while giving hers.

 Who would want to go to a pile of frozen rocks?

It is much better to dive into the warm waters of the hot springs.

"Come to think of it, that makes sense, let's go then!" Mitsuri agreed with Daki as she remembered the feeling of soaking in an onsen.

Her enthusiasm could be seen as she held her face in her hands and her eyes shone brightly.

"Wait a minute, I'll ask Shinobu and Kie if they want to come along." Then Lucian was teleported to another room in the castle.

The room where Shinobu was training hard.

She swung her peculiar-looking sword with tremendous speed, her movements were so fluid that they resembled a dance, however most people could not enjoy it due to the high speed at which they occurred.

Having become a demon, several of her strength and resistance problems had been resolved, in addition to the fact that her sword now generated poison by itself.

The combination of these and more aspects raised his combat power to a whole new level.

"Did something happen?" Shinobu asked when she saw Lucian approaching, in her opinion, he wouldn't show up for no reason while she was training.

"We're going to Hokkaido to enjoy the hot springs, do you want to go too? I think it would be good for you to get some rest" Lucian said, at the same time as he pointed to the various training dummies destroyed around him.

"...You're preparing for war and you can still think about going to the hot springs with your wives?" Shinobu was simply speechless.

'How can he stay so calm like that?'

"Yes, you can't fight when you're tired, right?" Lucian shrugged.

"...Alright, I'll go with you" she said after looking at him with empty eyes.

'I think I can continue training later' she thought, after all it wasn't every day that he invited her to go to the hot springs.

"Great!" Lucian nodded before leaving, after calling Shinobu, he would ask Kie next.

'Having the infinite castle I think I'll end up getting lazy.' Lucian sighed as he appeared at the Kamado family's house.

Soon he found her who was finishing washing the dishes.

Coming closer, he hugged her from behind and smelled the pleasant scent of her hair.

Oh! He shouted Kie as he felt someone hugging her, and quickly looked back, sighing in relief when he realized it was Lucian.

"You could warn me before doing this!" Kie exclaimed with a bit of anger at being scared by him.

"Hahaha, sorry, but I came to invite you to the hot springs." Lucian quickly apologized as he laughed, before releasing her and stating his purpose.

"I have to take care of the children, so I won't be able to go" Kie replied, a little sad about refusing this meeting.

"We can ask Kokushibo or Nakime to take care of them" said Lucian, Kokushibo already had children and considering how calm he is he could easily babysit, and would also help with training Tanjiro and the others.

Nakime is also very calm and she could let them play in the infinite castle space.

"Then I will accept." Kie was already in the mood, so with a little persuasion she soon accepted.

Hearing this, Lucian smiled, happy for her success, before taking her to the infinite castle.

"Now that we're all together, let's go to Hokkaido" he said, opening a door there.
