Immortality System: The Last Human's Transmigration

"While I think the runes are self-explanatory, I'll explain them anyway," she said before looking up slightly and beginning-

"Battle runes. While man arcane mages use this type of rune, it is in my opinion, the least important one." she explained, making me raise a brow in surprise.

"Battle runes are mostly used to make traps, or for those who haven't reached the astral plane or have weak cultivations, it can be used to make a spell without a chant which makes most people refer to them as arrays.

Think of it as the written version of a chant if you'd like. However, there are a small number of well sought out mages out there who use battle runes as a way to make enormous spells that either expanded throughout an entire city or nation or had the power to wipe a city or nation out." She explained and stopped speaking for a while, trying to decipher my expression as I quickly thought of many ways this might have been used.

'Hmm. With that explanation, I can easily identify many ways runes might have been used. Yes, it can be used the same way one would use traps in the wild or secret areas, runes are much more than that. I can already imagine all the defensive formations that kingdoms and empires have, but at the same time, I can't even imagine the scale of destruction that would be created in the wave of one of these runic spells.' I thought inwardly as an image of a nuke dropping to the ground and decimating everything in site flashed within my mind.

"Tactical runes on the other hand, while capable of being used in traps, cannot make the trap itself. A battle rune uses the mana within it as well as the elements within it to create a trap and the most common one is usually an explosion trap." Blanca explained once again before continuing after seeing my nod of understanding.

"Tactical runes can be thought of as rivers. While the energy might be stored somewhere else, tactical runes can be used to become a link between a source of energy and an absorber of energy. Many people use tactical runes to direct the flow of mana toward them so they can cultivate more efficiently since there is a higher density of mana around them. It can also be used to power objects such as those crossbows the elves use as well as those guns that the dwarves use."

'So like circuits of mana... or maybe just wires. From what I can tell, these tactical runes are probably just the mana version of electric wires that we used to use to power everything from phones to cities. While I'm sure they won't work exactly the same, the core principle is almost identical to my Earth's counterpart.' I thought to myself while scratching my chin in interest.

"Finally, enchantment runes are self-explanatory. With a combination of runes, you can change the properties of the thing the runes are situated on, whether that is a body, a weapon, or a piece of armor, that is up to you. ]

​ However, I must warn you that the act of inscribing runes onto one's own body is considered taboo and is only permissible when the runes are naturally formed through the creation of a unique body constitution, whether that would be at birth or from a legendary artifact is up to luck." She shrugged and tried to move on, but I quickly stopped before looking at her forehead where the red symbol still shone as brightly as before.

"So you have a unique body constitution?" I asked her with a raised brow.

"Of course I do. I am one of the most unique prodigies of the white snake tribe after all." She let out a subtle smirk that almost caught me off guard, yet I did not waver as I simply looked at the symbol on her head.

"So what does it do?" I asked with a tinge of curiosity.

"Well, since I've only unlocked half of mine, not much so far. It just increases my intelligence and gives me the ability to morph into any race while retaining the ability to use my body just as well as I would have if I was in my snake form. Due to this unique body constitution of mine, I also became exceedingly beautiful no matter what race I chose to show up as." She grinned with pride emanating out of her, gushing and flooding out of her like a volcano.

"Is that it?" I asked, raising a brow once again.

"Well, that's the overview of everything. Of course, there are ranks to runes as well as different languages one might use to make runes. Also, while the majority of runes are universal, there are ones that are completely unique to certain elements but that isn't something you should know about now." She explained before causing me to nod slightly.

I didn't want to be too in over my head so I went and took the easiest path to learn about runes.

'I guess I'll have to start off slow before beginning to speed up a little.' I sighed and looked at Blanca once again.

"So I'm guessing I first have to understand the book with the basics of all runes. Am I correct?" I asked

"Yes, and I'll help you learn anything you struggle with. In the meantime, since I don't have anything else to do I'm just going to start making you the armor and weapons you asked for." She replied with a wave of her hand, but when she looked at my face she was left stunned.

An elated expression hung on my face, indicating how much her last words meant to me.

'At long last! After suffering for weeks due to the lack of any defense points, I am finally going to have armor again! No longer will I feel naked in front of a strong enemy! No longer shall I be forced to dodge at all costs!' I inwardly shouted while the urge to hug the life out of Blanca began to rise within my chest.

However, unlike my desires, I was not stupid and instinctual. I quickly killed that desire where it stood, but my gratitude towards her did not diminish even though I knew that she was only doing it because I had been asking for almost a month now.

"Then let's get started!" I shouted and snatched the book out of my storage and began reading it.

And before I knew it, a month had passed.
