Runemaster in the Last Days

Riya arched her eyebrows.

She could guess what Samuel was thinking.

Unfortunately…

"No, it's not," Riya replied. "The size of the crack is different, so the size of the formation that I make will also be different. It's impossible for the safe route to be exactly the same because there will be some deviation when compared with the size of the formation and so on."

Size of the formation?

Samuel looked at the crack in front of him blankly.

Sorry, he wouldn't be able to understand it, then.

Riya chuckled. "If you want to, I can teach you how to calculate it, but you better have good foundation in maths. Otherwise, you might want to vomit because of how complicated it is."

"I have good result in economy and management. There are some maths there, but I don't know how complicated the maths for formation calculation is," Samuel replied slowly.

Economy and management?

This time, it was Riya who had a blank look on her face.

Her course in the university back then was far away from these two topics. After all, she dabbled in things related to technology and stayed far away from economy.

After coming back to this world, she did review the lessons she had learned back then. Four years gap was not so easy to be overcome. There were many things that Riya had forgotten.

Thankfully, the basic was still there and Riya could learn everything from the beginning once again. It was more than enough that she managed to finish her thesis and defense back then.

But if she was asked to be as proficient as she used to be…

Then sorry, Riya didn't have that ability.

Four years in that world had already rewritten most of her memory into that of runes. She was far more proficient in drawing countless runes compared to writing program like before.

While Riya did think that it was a pity, but she didn't regret it.

If she truly wanted to, she could learn more after she had reached a certain ranks in the future and didn't have much hope for improvement anymore.

But that was for the far future.

It was definitely not something that she could do anytime soon.

The other good thing about her courses was the fact that she had to be good at math. Otherwise, one would be crazy when they thought about some things that had to be written in the code programming.

"Well, I don't know if it's relevant… but I'll try to teach you," Riya finally said with a sigh.

Samuel arched his eyebrows. "Is it fine for me to know these things?"

"It should be fine?" Riya tilted her head. "What I will teach you is just the common sense that even low ranked formation master will learn. Because a formation master didn't only need to be able to make formation but also know how to create the backdoor and loopholes. Afterwards, you have to be able to break down a formation yourself."

This was the common sense in that world.

The runes alone didn't have much meaning or their power was extremely limited until they were combined together to form formation.

A formation is a combination of countless runes, working together to create the effect that their maker longed.

"So… is it used universally?" Samuel asked carefully.

"Not really. There are types that you need to watch before you can count the escape route or the backdoor in the formation," Riya replied and then tilted her head. "To be honest, people without talent to be rune master might find it difficult… because you can't see the mana fluctuation in the air."

"Huh?" This time, Samuel was stunned and they had entered the crack. They easily bypassed the formation that Riya made and Samuel could see a magic beast rushing over only to be chopped into countless pieces.

"What?"

"Can you see… the mana fluctuation?" Samuel asked, his throat was a bit dry.

He knew that they could sense mana when they were meditating and then able to guide the mana into their body. After that, as long as they concentrate enough, they would be able to sense mana's fluctuation within their own body and when others were using magic spells or anything like that.

But on normal times, it was not that easy to detect mana within a person's body, no matter who they were.

And directly sensing mana in the air… it was even more outrageous.

"Ah, I didn't mean that I can sense the mana concentration in the air… that kind of thing is definitely impossible." Riya rolled her eyes as she continued to walk forward and then stopped before making the Protective Rune Circle.

This formation is simply the best when she wanted to do something.

As for the mana concentration in the air… it was impossible for her to detect without meditating on the spot and try to compare the result with her usual meditation or something like that.

"Then…"

"What I can sense is the mana fluctuation from the runes itself. When the runes are not activated, they will not actively stir the mana in the air and will usually lay dormant. It will remain undetected most of the time… but not for rune masters."

Riya looked at the formation that had started operating in front of her and the magic beasts that were directly slaughtered in front of her.

"I know that you can't see it, but for me, the entire place is covered with runes. Not all of the runes are visible, so I don't know their exact uses, but from the moment I step into this crack, I know that there are runes all over the walls… or more like, the entire place is under the effect of a formation."

It was precisely because she could see this that she knew the existence of those pillars and what formation it used after some investigation.

This could be said to be a kind of talent for her…

But whether this talent is a good thing or a bad thing, Riya didn't know.
