( Yuuki's POV )
When I began to analyze the evil pieces Ravel was observing me quietly, the evil pieces emitted a similar energy but they were not completely the same, Was that because they were different pieces or because they were from different devils, maybe a little of both.
The principle of the evil pieces was similar to our Sekirei operation and the arcane card that Ranko gave me, with this I believe I could produce an infinite number of arcane cards, The effect may be a little reduced but in the future, I can make them more effective, also
they can also serve as a security system, I can make the frame gears only activate when they detect the registered arcane card.
I immediately created some new arcana cards and tested them on myself, they were safe but since I already had the death arcana inside me, I didn't feel an increase in power, the effects didn't stack.
Ravel: what are those cards?
Yuuki: something similar to the evil pieces of you devils, they give a good increase in power but they do not affect your race, A human with one inside him will stay human and these could be removed at any time.
I extended my hand towards Ravel and the blue card came out from the back of my hand, Ravel immediately took it and she began to inspect it, Then she put it inside her and this time I could feel the increase in power.
Yuuki: what do you think? Not bad, isn't it?
Ravel was left feeling the increase in power and then she extracted the arcane in the same way as me, She looked at me seriously for a few seconds before speaking again.
Ravel: ...hey, do you think you could remove the evil piece inside me?
After saying that Ravel explained to me some of what she knew about the evil pieces, That was interesting information and the reason she wanted it removed was because she was part of her older brother's peerage, and he could teleport her back to him through that, It seems that I gained some of her trust and before returning to the castle I extracted the evil piece and we talked more about devils and their culture.
/////////////////////////
The next day the ban on my training had been lifted and I was able to train together with the girls, today we were all very excited about our training, Now that Miu and the others got the last piece we needed to open a portal to a god's domain, soon we would have our first fight against a god.
Today I wanted to see the limits of my new power and since Ravel was watching so I wanted to show off a little, I gathered my energy and activated the dragon armor that I used in my fight against me, then I threw some punches and kicks to test my strength, Every movement I made created a gust of wind.
After that I tried a new fighting mode that was mostly focused on physical power, I modified my armor and created two extra pair of bone arms, I used [Boost] to my new limit, 777 and called it [Lucky Boost], at the same time I activated my skill [Storm body], I used half of my energy to maintain these abilities and the other half to heal my body that was under constant pressure from the same abilities, I call this my asura mode.
Our new training ground could create training enemies and in front of me a dozen living armors similar to me appeared, but these were white, one of them moved fast and appeared in front of me, it threw a punch at me and I blocked it easily, that wasn't weak but in my current state I didn't feel anything, I swat away the armor and it crumbled in the air, then I moved in an instant in front of the armors and threw a powerful fist at them, the power of my attack destroyed four of them, and I finished off the rest with other quick attacks.
For my next test, the training ground created ten stone cubes fifteen meters long, I gathered my power in my three right arms and released it in a triple attack, a [triple shot], All the cubes collapsed, then I undid my armor and a wave of fatigue fell over me, for the moment I think I will only be able to maintain that asura form for about fifteen minutes.
While I was taking a break I turned to Ravel and she then walked towards me.
Yuuki: how about that? You still think I'm not strong.
Ravel: ok I won't say that again, are you okay, you look tired.
Yuuki: That took a lot out of me but I'll be fine.
Ravel: ...here, you can have this.
Ravel took out a small ornate glass bottle with a red liquid, I took the small bottle and looked at the young devil questioningly.
Yuuki: what is this?
Ravel: These are phoenix tears, this regenerate magic and heal wounds, only my family can create them, that is why we are so important and wealthy in the Underworld, so be grateful that I'm giving you one for free.
Yuuki: ok, thank you very much Ravel.
I patted Ravel's head and she looked down in embarrassment.
We all continued training for a while before starting our daily routines but before that, I was called by a member of the adventurer's guild branch in our kingdom, They wanted me to take care of the extermination of a dangerous monster and I of course quickly accepted.
The monster was a Catoblepas, this monster had the annoying ability to turn anyone who looked into its eyes to stone, In addition to exterminating a dangerous monster, I had another reason for accepting the mission and that had to do with the sword that Kalawarner had sent, It was damaged and if it were a normal sword I could repair it immediately but that was a weapon made from living monster parts and I didn't have much experience or materials for that.
