Reiner originally thought that the Flame Burst was just a slightly larger fireball, but he didn't expect that the Flame Burst Technique released in his hand would have the destructive power to destroy a small mountain.

Even though this is Reiner's heart lake, the power of the spell will be a little off, but this is too far away.

The only thing that can be compared to it is about the eternal blazing sun of Lanchester engraved in the Hohenheim Gold Cup, but it is a four-ring spell, and purely in terms of power, it seems to be similar to this flame bursting technique.

Do you really have the potential to become a bombard?

"Wait a minute......

Reiner suddenly realized a problem.

Previously, he believed that spells were quite low in their use of mana, and Reiner's own improved fireball spell was much more destructive than standard spells due to the use of Hydra, an element that burns very efficiently.

But now, the second-ring spell Flame Burst has increased its destructive power by more than a little bit after using the Hydra element as its base, and although this phenomenon seems to be nothing to explore, Lena has noticed something strange in it.

"Could it be that compared with the first-ring spell, in addition to some expansion of ability, there is also an increase in the efficiency of the use of mana?"

This is easy to understand, assuming that Reiner uses a fireball spell and consumes one unit of mana, then if he wants to cast a more powerful flame blast spell with the same utilization, he will naturally need to consume more units of mana.

But in reality, whether it's using the Fireball Technique or the Flame Burst Technique, Reiner consumes one unit of mana.

In other words, Flame Burst has a higher utilization rate for the conversion of mana.

From here, it can be inferred that among similar spells, the efficiency of the three-ring spell should be higher than that of the second ring, and the four-ring spell should also be more efficient than the three-ring.

"Originally, I thought that the so-called ring number was just an indicator used to distinguish power, but now it seems that the number of rings of spells is actually an indicator used to distinguish efficiency!"

This is something that most magic texts don't cover, and it touches on basic issues like the definition of a spell, and it is of little help to a pragmatist mage.

"It's no wonder that some seemingly simple spells have three rings and four rings, while some powerful spells have only two rings."

Reiner has some understanding that this is not an exploration of the world, but it can also help him learn magic better and improve his magic in the future.

"Because of this, higher efficiency requires stronger computing power and control ability, and the forced use of high-level spells by low-level mages will not only cause physical weakness due to mana overdraft, but also the load caused by the overclocking of the brain."

Since it was within his own heart lake, Reiner didn't care about the expression, and used his own familiar way.

"If you use a computer to describe it, spells are applications, high-level spells are more efficient programs, low-level spells are more primitive, simple and inefficient programs, and the use of spells to hurt the soul is actually a lag or even crash caused by forcibly opening large programs in a certain sense when the configuration is not enough!"

With such a transformation, he felt suddenly enlightened.

"If you think about it this way, those Nine Ring Spells, I'm afraid the utilization rate of magic power is already quite high."

Reiner recalls the high-level mages he saw in Ernest who could easily cast spells that affected a wide area, and in addition to the high-level mages themselves, the spells he mastered were more efficient.

"Wait a minute, in this way, is it also ...... for a high-level mage to suppress a low-level mage?"

Rank suppression would make it almost impossible for a low-level mage to summon external mana to cast spells, and in the past, Reiner had imagined it as a pattern of two vortices, one large and one small, and now he could add some assumptions to this.

"Will the magic always flow spontaneously towards more efficient use?"

On Earth, Reiner knew that there was a theory that light would always find the shortest path to move, and if magic was a similar substance in this world, it didn't seem unacceptable to flow into more efficient magic.

"You can check out the relevant books later."

Reiner didn't have a reference on the earth for magic, and he didn't have too many books on the nature of magic, so his current conjecture might have been put forward by other mages a long time ago, and even proved it, and if that was the case, he would have a doubt.

After confirming the spell model of the brand-new Flame Burst Spell in the Heart Lake, Reiner suddenly felt that it was possible for him to turn the three-ring spell into a stronger fireball spell in the future, and finally rely on a fireball spell to go all over the world.

"There's no problem that can't be solved by the fireball technique, and if there is, let's do it again?"

Smiling dumbly, Reiner, who had completed today's task, pulled his consciousness back from his heart to reality.

The hot summer night was still uncomfortable, and the open window blew a little hot wind, making the parchment on Reiner's desk tremble slightly.

Everything seemed to have never changed, but at this time, Reiner's heart lake was already engraved with the second-ring spell Flame Burst, and from a practical point of view, he was already enough to be called a second-ring mage.

You must know that it was only a week since he became a one-ring mage, and even if you think about it, based on the time when he inscribed the one-ring spell into the heart lake, it was only two months.

In two months, from the first ring to the second ring, this speed can be said to be very fast.

Now, as long as Reiner registers with the local Magic Association and goes through a simple assessment, he can become an official Second Ring Mage.

But he wasn't going to do that.

It's not that he wants to deliberately suppress his advance speed to cover up anything, Reiner has received so much feedback from the world, and it makes sense to advance quickly without arousing any suspicion.

Reiner was just plain lazy.

Registering for an advanced trip to Torundo is just a title in name, and becoming a higher-level mage will inevitably encounter more transactional troubles, and Reiner doesn't want that.

He felt that he would simply save it and wait until he was promoted to the middle level, which would not only save time, but also save a lot of trouble in the middle, and I believe that everyone in the Magic Association could also understand.

With that in mind, Reiner put away the papers on the table, and suddenly felt as if something was missing today.

After thinking for a moment, it dawned on him.

The tiger-striped kitten didn't come to check the post today!

Before, when writing a paper or inscribed a spell, the cat would suddenly appear, as if patrolling its territory, but today, it was nowhere to be seen.

"Did you oversleep or something else?"

Reiner thought as he stood up and looked out the window.

Soon, he saw that downstairs under a tree, Fina was feeding the familiar kitten with jerky, while carefully stroking the kitten's head for fear of scaring the other party.

"So here."

Sure enough, compared to yourself, is it still a cute girl who is more worthy of getting close?

Thinking out of nowhere, Reiner smiled, and he didn't bother the two of them soundly, sat back in his chair, and glanced at the calendar on the wall.

The Moon of White Dew is halfway over, and there are only a few days left until Elimia's birthday.

And the day when the third generation of peas ripen will be tomorrow.
