Compensation θ ~ I might be late for reincarnation, but since I was born as the talented eldest son of a prestigious noble, I might be on the winning side.

Inside my body, there are lifeforms called [Rex Trinity].

Their gender is unknown, and their communications abilities are still under development. However, their abilities are undoubtedly excellent, and they significantly enhance my own abilities while coexisting with me.

These crucial symbiotic Reason Insects have three base forms. Two of them have already hatched.

The first one is [Araneola],

It’s responsible for creating and repairing magical pathways. It forms a dual spiritual partnership with me and Ai, acting as a companion in the development of the [Emperor of Reason] abilities.

The second one is [Luciola],

It’s a clone made from a part of my body (in this case, a part of my hair), often used as a scout or for information gathering while separated from me, just like a drone. It has a mesh-like appearance when integrated with me, but when separate, it frequently mimics itself as insects, birds, or snakes.

And now, the third one.

Although it has taken quite some time, the moment has finally come to hatch the final [Rex Trinity].

“What is the third one going to be responsible for?”

《It will handle magical armor and magical attack, in other words, offense and defense. 》

Magical armor is a term I’ve come across during the explanation of [Reason]. It’s supposed to be a form of magical body enhancement.

“Magical armor is acquired when you master [Reason], right?”

《Yes, that’s correct. When using magical armor, sharing its operation with a [Rex Trinity] enhances safety and expandability. 》

“What can it specifically do?”

《One thing it can do is an automated interception system and handle defense from blind spots. 》

That’s amazing. I definitely want to use that. If I become well-armored in all directions, I can avoid surprise attacks and easily detect any traps set against me. As Ai said, my safety should improve drastically. If I ever get a chance to explore dungeons (and bulk up), this ability could be incredibly useful.

“Anything else?”

《One more thing is that it can register the magical patterns of magical beasts or humans as data for storage and reference》

Hmm, can this data storage be used as a security system?

“How do you use the stored data?”

《It enables rapid identification of species or individuals and allows for location tracking and remote surprise attacks. 》

Wow, it can do that much? Remote attacks are extremely convenient, and its applications are broader than I expected.

“But do we need to hatch it now? In my current situations I think it’s rather unnecessary”

After all, I’ve just turned seven. I’m still physically underdeveloped, and I can’t handle the load that comes with using the magical armor. Moreover, I have a significant number of bodyguards with me. Trained adults will protect me, so I don’t think I immediately need self-defense capabilities.

《No. This is precisely the right time. Beyond the [5th Reason], there are powerful guardians if you want to advance further, a trial if you will. 》

Oops, that’s new information. It would have been helpful if you’d started with something so important.

“Guardian? That’s the first time I’ve heard that term.”

《I introduced the term ‘Guardian’ for the first time this time. Until now, I’ve used expressions like “it’s not going to be easy”. 》

I see. I’ve heard that before. [5th Reason], the so-called advanced magic and anything beyond that, have formidable Guardian.

Breaking through them would mean that we’d have to face them as opponents. This would almost certainly involve combat. That’s what makes it so challenging.

“Can the third [Rex Trinity] help me overcome those trials?”

《I expect that, with time and effort, you’ll be able to overcome [5th Reason], [6th Reason], and [7th Reason]. 》

Oh, that’s good then.

“What about the ones beyond that?”

The [8th Reason] magic is known as a catastrophe-level magic. It could lead to dangerous situations if misused. So, even if I can’t use it, it probably won’t create problems.

However, “having the ability but choosing not to use it” and “not having the ability to use it” are different. If [Emperor of Reason] represents the pinnacle of magical professions, there’s an element of personal pride or honor urging me not to sit idly without making use of it.

《[8th Reason] is known as catastrophe-level magic and, this level is on par with the magic used by dragons. 》

“…Dragon? THAT dragon?”

《Correct》

“Does dragon even exist?”

《Yes. Although they do not appear near human settlements, but yes, there are various forms of dragon species on this continent》

… There’s a dragon in this world.

Well, to be fair, there is a mountain range called “Sleeping Dragon Mountains” in the west of Spirit Forest. I thought it was just an influence from an imaginary creature, or a creature that lived in ancient times, but it turns out that wasn’t the case.

“If I reach that level… is it possible to do something like a [Dragon Breath]?”

《Although it doesn’t really come out from your mouth, but it is possible to do something similar》

That’s amazing. The problem is that it depends on my growth, but if it’s within my reach, it’s not a bad idea to work hard to achieve that level.

《 Next, the [9th Reason] is considered divine-level magic and it is said to deal with the world’s mechanisms. Then the [10th Reason] is said to be God-level magic, it is a magic in the domain of the Gods》

Ah, those two sound quite formidable. I would rather not touch god-level magic.

That’s because, in this world, gods are entities that can bestow and withdraw blessings at will. Stepping into the realm of gods without being careful would be unwise. They could quickly issue divine punishment or something like that.

“In essence, I understand. When the [4th Reason] is complete, it means there isn’t much time left. Got it. Let’s proceed with hatching the third [Rex Trinity].”

《Very well, let’s begin the preparations for the hatching right away. Please wait for a while until the hatching is completed. 》

“I leave it to Ai. By the way, what’s the name of the third reason insect?”

《It’s called [Scara].》

“Araneola, Luciola, and Scara. All of them have great names.”

《Master, I have one more piece of information to share. Although it’s about future plans, we’re going to expand Luciola’s capabilities. During that time, we’ll need you to refrain it from separating from the main body for a certain period. 》

“You mean I should do scouting and information gathering now?”

《Yes, since this place tends to be noisy, it’s recommended to have a better understanding of the surrounding situation. 》

“Thank you for letting me know. There’s no harm in being cautious. I’ll check it out.”
