The Heart of Molten Fire is extremely dangerous, especially after the outer layer of black stone is stripped away.

The usage of the Heart of Molten Fire is quite simple, which is to use magic power to shatter the outer crystal, and then begin to comprehend the power of fire element rules.

But this process is very dangerous.

When the crystal of the Heart of Molten Fire shatters, it emits high temperatures and can even produce extremely high-temperature flames.

One wrong move might result in death by high temperatures and flames, so one must prepare protection in advance.

Herag wasn't too worried about this because he possessed the talent ability of the Dragon Race bloodline, high-level flame resistance.

Still, to be cautious, he armed himself fully to avoid any accidents.

Once Herag was ready, he held a small red crystal in his enormous palm.

He slowly infused it with some magic power, and as the magic power entered, cracks began to appear on the crystal exterior of the red crystal.

A few seconds later, with a crisp sound, the red crystal shattered instantly.

At the same time, the surrounding temperature rose sharply.

Even in his current form, Herag felt the temperature around him was a bit too high, estimating it to be around 200 degrees Celsius.

Ordinary people couldn't survive such an environment, and even Herag felt uncomfortable.

He endured it with effort, adjusting his state as he began to carefully comprehend the rules.

His past experience as the Master of the World benefited him greatly, especially during the comprehension of rules when his past experiences proved very helpful.

Herag had once "seen" the existence of most rules and had clearly felt these rules.

At this moment, for him, as long as the fire element rules showed even a trace, Herag could quickly capture it.

The temperature in the laboratory gradually increased, reaching an ambient temperature of over 300 degrees.

Some flames appeared abruptly, burning vigorously in the surrounding air.

Herag closed his eyes and keenly sensed the fleeting fire element rules, then began to comprehend them.

The extreme heat around him seemed imperceptible as he fully immersed himself in comprehending the fire element rules.

Herag's absolute defense kept up, blocking the approach of those flames.

But it couldn't block the high temperature, which had risen to 500 degrees.

Herag felt that without his high-level flame resistance, he wouldn't be able to endure such a high-temperature environment for long.

The Key of Rules like the Heart of Molten Fire belongs to a very dangerous category.

There are many kinds of Keys of Rules; some have no danger, while others have very harsh usage conditions.

Half an hour later, Herag opened his eyes, having successfully comprehended the power of fire element rules.

The surrounding temperature slowly decreased, like a boiling pot of hot tea after the heat source is removed, gradually cooling down.

Nonetheless, the process was quite slow, and the temperature drop required some time.

Herag did not rashly leave the basement because the temperature in the laboratory and outside was too different. Suddenly opening the door would cause problems.

Although it wouldn't affect him much, Reese was still at home, and Herag didn't want her to get hurt because of this.

Herag reached out and touched forward, feeling the time, space, and fire element rules he could see, just like when he first saw free energy particles.

The rules he saw now had no physical form; they existed but were intangible, yet omnipresent.

As he waited for the laboratory temperature to drop, Herag pondered which second-level fire spell to learn.

The power of rules can be comprehended in advance, and after successfully comprehending it, one can directly learn the corresponding magic.

Herag didn't plan to exchange second-level fire spells from Serlandir's Secret Vault, as contribution points were becoming increasingly important to him.

Second-level spells can be obtained through other means with magic stones, but contribution points are very hard to accumulate.

Serlandir's Secret Vault is currently the only stable way to obtain a Key of Rules, making the required contribution points even more valuable.

Now with only 1600 contribution points left, Herag was worried about how to gain more.

It still seemed that participating in the plane opening war was the fastest way to gain contribution points.

But recently, there seemed to be some issues on the Elf Plane side...

Herag had only heard a little, without much detail, and the Expedition Team hadn't revealed anything externally.

Parker was still recovering from injuries, staying continuously in the Floating City above Silver Moon City, and hadn't appeared once.

Herag had a vague feeling that something significant must have happened inside the Elf Plane.

...

The next morning, Herag arrived at the Pointed Hat Magic Shop.

The Pointed Hat Magic Shop is a famous magic shop and considered a family business operated by the Clare Family.

This wizard family also has a very long history, reportedly tracing back to the distant Era of Radiance.

However, no one can verify this, as many wizard families claim to be ancient families existing since the Era of Radiance.

In reality, they might be only a few centuries old.

Herag had made an appointment in advance and had informed the shop owner Terry in Silver Moon City about his needs beforehand.

The Pointed Hat Magic Shop usually sells level 0 and level 1 spells, and level 2 spells are very rare.

To avoid wasting a trip, Herag had Terry prepare in advance.

Among second-level spells, time and space magic are the rarest and very uncommon.

But second-level fire spells, being elemental, are relatively easier to find.

At least through the Clare Family's channels, there's no issue.

"Mr. Terry," greeted Herag as he entered the Pointed Hat Magic Shop.

Terry was a young man who appeared to be in his twenties and also a level 2 wizard.

Herag had met him before in social events like dances, although they weren't very familiar due to not much interaction, but they understood each other somewhat.

"Mr. Herag, you're here. I have prepared three second-level spells for you this time. See if there's anything you are interested in," Terry said, taking out three thick books from his Space Ring and placing them on the counter.

"These three spells are: 'Fire Element Flight,' 'Thermal Reversal,' and 'Eternal Night Heart Flame.' Have a look," Terry introduced.

Herag curiously examined the three spell model books and said, "Let me take a look first."

He intended to briefly review the three spells to understand their characteristics before deciding.

The first spell Herag looked at was 'Fire Element Flight,' which utilizes the power of fire element rules to cover the body with a thin membrane of elementalization of the fire element.

With this membrane, one could fly through the sky at an extremely high speed.
