The rest of other matters and concerns in Inazuma needs time, and with nothing to do Ei decides to explore outside for a change.
" I would like to see what kind of experience this world would give me." Ei said to both her Subordinates
" I thought it was ' I will explore the world to get stronger!' or something like that Master." said Tomoe as she do maintenance with the curved sword that looks like a katana, since the dwarves have yet to bring out results due to how really hard to make a high-quality katana suitable for a powerful being as Tomoe.
" I already did that during my travels in the Void and what I need is spiritual, mental and willpower training which cannot be acquired so easily. There will be a time where you will be blocked by a wall Tomoe, a wall that needs a lot of time to breakthrough in order to reach the next dimension of power. As of now you and Mio are still relying on brute force and skills assisted by magic power to manifest, I want you both to at least reach the conceptual level where you can unleash your ability as conceptual power."
Both Tomoe and Mio are having question marks on top of their heads, making Ei sigh for a bit thinking maybe its to soon for them but she already said it so no use stopping it and she continues to tell them.
" Conceptual power comes from the root word 'Concept', a phenomenon capable of breaking the laws of the World." Ei raise her hand and release a small spark of lightning in front of them and she asks, " Will you both get hurt with this tiny spark of lightning?"
Both shake their heads, confident of their magic resistance as they saw Ei flick the spark towards them only to feel a sharp pain and a numb feeling on their body.
" And now?" Ei asks and they both nod with a bit of difficulty due to what happened earlier.
" You both are wondering, ' How did such a tiny spark affected us?' the answer is that spark is not done through magic but me using conceptual power and you two has no defences about it whatsoever."
Both widened their eyes as they actually witnessed an event where usually only happens when two Gods fight.
" Conceptual power are powerful because of its user's mastery over their Domain or Divinity, Gods and beings in that level are all capable of using it. None of you can defend it because both of you are still on the stage where you use your power thru magic, using magic is actually bending the laws of the World. Bending it means you still under the scope of the World's laws. Using conceptual powers is strong but it leaves a scar to the World hence Gods seldom fight in a world and mostly on the Void. This lesson is still way above you two but I still decided to tell you both so that in the future it'll be easier for you to acquire it."
Such info dump can only make them nod but still it lit a fire to both Tomoe and Mio, a fire to drive them to get stronger.
Ei then called Ema and told her to contact the craftsmen for the preparations to visit the world Outside of Inazuma.
