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.
