Herag's physical body has now reached the realm of rules, and only the power of rules can affect it—ordinary sword attacks and energy attacks have no effect anymore.

This means that even if Herag stands motionless in front of a Level 1 Wizard, the wizard would find it difficult to inflict any harm using all their magic power.

Now, anyone who could pose a threat to Herag would at least need to be a Level 2 Wizard, and one who has a high level of mastery over the power of rules.

Herag feels delighted, as if he has gained an incredibly sturdy protective shell.

However, he also knows not to be careless; at least Level 3 Wizards could still potentially injure him severely—he cannot act recklessly just because he has the World Furnace.

Herag recalls deciphering the World Furnace spell, learning that its goal was to transform every cell in his body into a mini-plane, thereby forming an endless plane within himself.

Initially, he thought it was just the creator's imagination, assuming that the creator himself might not have reached such a level.

But now it seems that, if it continues developing in this way, there might be a slight hope of reaching that realm.

Herag said, "Such an incredible spell, I wonder who created it?"

Although he obtained two stone slabs, there was little information about them, knowing only they were inherited from an ancient tribe.

He was uncertain about which plane this tribe existed in, or if it still exists.

The Toad suddenly said, "It probably relates to the ancestral bloodline within you—a mere spell couldn't have such an effect."

After pondering, the Toad believed that although the spell was indeed powerful, it probably couldn't reach the level of forming an inner domain.

He hypothesized that it was likely because Herag's bloodline is strong, possessing not only the highest level of ancestral bloodline but also other powerful bloodlines.

Under the augmentation of such strong bloodline, coupled with the World Furnace spell, and the fusion of various rule powers, Herag accidentally formed his inner domain.

Herag thought so too, realizing that without sufficient strong bloodline support, a normal person's body couldn't withstand the formation of an inner domain.

With an inner domain within a normal person's body, it might directly burst apart.

Herag didn't feel any discomfort during the process, thanks to the ancestral bloodline being incredibly strong, capable of sustaining such power.

He now somewhat understands why the prerequisite for learning the World Furnace is having the Great Dark Heaven as a talent spell.

Only by using the Great Dark Heaven to absorb sufficient and powerful bloodline can the body sustain such a magnitude of rule powers.

However, the inner domain probably wasn't in the original concept of the World Furnace spell creator—Herag's situation seems like an accident.

With an inner domain as his shield, Herag finally has an additional card to protect himself.

Yet compared to the domain of a true Level 4 Wizard, this inner domain is still far inferior.

A Level 4 Wizard directly expands their domain, and within it, they are the dominator.

Unlike Herag's inner domain, which cannot affect the external world—it merely makes the body strong enough.

Inside Fallen Wings there is only one room, so Reese and Asuna are sitting on the sofa beside watching and listening to Herag and the Toad talk.

Upon realizing the power of the inner domain, they naturally felt genuinely happy for Herag.

They also became curious about the Toad but instinctively didn't inquire.

Herag didn't explain much about the Toad's situation for his reasons, and the two women wisely refrained from asking.

Yet Reese and Asuna were aware that the Toad is not merely a simple messenger but must be an unimaginable supreme entity.

Previously, they wondered how Herag would reach the Elf Plane.

Unexpectedly, with just a word from the inconspicuous Toad, they arrived at the Elf Plane in the blink of an eye.

The level of power required is beyond the understanding of two Level 1 Wizards.

When exchanging thoughts with the Toad, the knowledge he conveyed was not something typical wizards in the Land of Dawn could access—it totally belonged to another realm.

Reese thought to herself, "My man is truly impressive; even casually signing a messenger involves a being of such caliber."

…

Three days later.

Herag has become largely familiar with the changes within himself these days, aligning with the Toad's description—it's akin to having an inner domain.

With such an inner domain, even shields like Absolute Defense are rendered obsolete.

In terms of defense, the inner domain is fully maxed out.

The Titan Power spell is still useful, greatly enhancing physical strength when used.

Herag is also considering starting to use Shenlan's Chip to develop some Second-level Spells.

He has already mastered many Second-level Spells, having carefully studied and learned each spell's model.

During this study, Herag acquired much knowledge.

These Second-level Spells themselves are developed by some highly skilled wizard predecessors, learning them also involves learning about their research process.

With enough samples mastered, Shenlan can begin to conduct research related to Second-level Spells.

Herag had such thoughts long ago, but previously his understanding of rule power was insufficient, making him wary of conducting research.

Rule power is very potent; even a small oversight could cause great harm—Herag must be cautious.

The essence of Second-level Spells is to use various rule powers to achieve different goals.

Simpler Second-level Spells might involve one rule and accomplish simple tasks, not requiring profound techniques in the application of rule powers.

More advanced Second-level Spells are more complex, possibly involving multiple rule power applications.

This requires learners to command multiple powers and demands highly skilled techniques from spell developers.

The coordination and activation of various rule powers are not trivial; the effects generated among them are extremely complex, necessitating thorough research.

Herag can now only utilize Shenlan for some simple Second-level Spell development; more advanced aspects are limited due to a lack of relevant knowledge, even for Shenlan.

The knowledge related to this realm is generally strictly controlled by major Wizard Organizations in the Land of Dawn and not readily disseminated.
