Isekaid 40ish Man Returns, Regressed as a Peerless 17-Year-Old - Chapter 1.4

It was my first night back here.

I’m currently on the dark side of the moon.

I am on the dark side of the moon to test how well I could use the abilities I had acquired in the other world.

I don’t think I would be able to use powerful offensive magic in this world but it would not be funny if I accidentally killed an opponent if I was teased on the street.

It is also important to know up to what extent I must avoid using my power.

For the time being, I was able to use physical barriers that would not cause problems in space, air compression for breathing underwater, invisibility, and high speed flight for breaking through the atmosphere without any problem.

Now, what should I try next?

Even though I am currently very far, at the moon, it would be troublesome if I were detected from earth.

Just to be safe, I cast a physical illusion-blocking spell over an area slightly wider than the moon’s diameter so that I won’t be visible from earth.

With this, it’s unlikely to be detected from earth.

After finishing my preparations, I focused my magic on my palm.

A black sphere at the size of my fingernail showed up and slowly expanded.

It has been proven that magic can be used in this world as well. That means not only that “I can use it” but that also means this world is compatible with magical phenomena.

Apple falls from the tree.

There are worlds where such a common thing doesn’t happen naturally.

It seems that the world in which I was reincarnated and the world I’m currently living operates according to similar principles.

Though that made me wonder why magic is not developed in this world.

I looked at the black sphere that’s as big as my fist in my hand.

The fact that it’s possible means that this world is also full of magic power.

For simple magic, it can be activated by the magic power inside the caster but for something like this… there’s no way it is possible without the existence of magic power around.

I gently pushed the black sphere forward.

It was hard to get a sense of direction in space but it moved forward at a speed faster than the speed of sound. Before long, it produced darkness equal to the size of the moon.

A starless darkness spread before my eyes and after a moment, returned to normal.

It is an extremely powerful magic that can even destroy planets.

I would never use it against humans and its destructive power was too great to control. However, it was necessary if I needed to fight against gods.

The magic power in space is about the same as the other world.

The magic is too dense for a world where magic doesn’t seem to be widespread.

Usually, the more magic is used in a world, the more the world is filled with magic power.

I’m going to leave this for now because it’s related to magic.

Though I can think of several possible reasons….

Well, others would think it’s only delusions.

For now, my experiment was a success.

I can use all the “techniques” I learned from another world.

The only thing left is my physical body which I have to work on in time.

There’s no way I’ll be fighting for my life in this world after all.

For today….

「Hmmm——-!」

I used my magic power to tear every muscle in my body to pieces and instantly heal them with healing magic.

I feel severe pain in my whole body but this alone has the effect of a month’s worth of solid muscle training.

After repeating this several times, my entire body became moderately toned.

I should be able to join pro sports.

For now, at least my body would be able to withstand the use of my own magic power.

I’m hungry….

I’m not sure how much I can make up for it with magic power but I burned a lot of calories.

My reach is also different from when I was still in another world.

I’d like to train in close combat but that can wait until tomorrow.

I don’t really need to go that far but I’m not comfortable with the idea of being unprepared for the enemy.

I think I’ll go home….

Immediately after thinking so, I felt a reaction from danger detection magic that I casted to Yui.

This evening, Yui seems strange so I cast it on her just in case.

When hostility swells around her, it will send notification to my brain.

I never thought that it would be activated. What’s going on?

I jumped from the moon back to earth.
