The Theory of "Cutting Steel"

Levy did not dare let her guard down in the face of Zoro's mountain-like, steady presence. She pushed her magic power to its limit, preparing to test him with the defensive magic she was best at.

"Solid Script: Stone."

With her sharp cry, magic power rapidly gathered in the air. Between her and Zoro, a massive wall of solid rock half a meter thick appeared out of nowhere! This was one of her usual defensive techniques, enough to withstand most physical attacks.

Yet Zoro merely glanced at the stone wall without even moving his feet.

He casually threw a straight punch forward.

No Haki, no flashy technique—just pure physical strength condensed to the utmost extreme.

"Bang—!"

A dull, thunderous impact rang out.

The stone wall that Levy had considered indestructible was like a block of tofu struck head-on by a battering ram before Zoro's fist. It instantly cracked apart from the center, countless fissures spreading like a spiderweb. Then, with a boom, it completely collapsed and returned to a sky full of glowing motes of magic.

"Too brittle." Zoro withdrew his fist and gave a flat assessment, as if he had merely broken a cracker.

Levy's little mouth fell open in an "O," her face full of disbelief. She knew Zoro was strong, but she had never imagined that even the stone wall she had formed with magic could be shattered by a single punch using nothing but physical strength.

"Then... what about this?!" Refusing to concede, Levy activated her magic again. This time, she used a higher-level spell.

"Solid Script: Iron."

An iron wall, thicker and heavier than the last and gleaming with metallic luster, rose from the ground! Its hardness was enough to rival the finest Knight armor.

"Oh? Iron?" Zoro finally showed a trace of interest as he looked at the iron wall. He reached out and rapped it with his knuckles, producing a crisp clang.

"This kind of thing," he said as he turned to Levy, in a tone as though it were only natural, "I can cut it without even using a sword."

Levy was completely dumbfounded. Without a sword... how could he cut through steel?

Zoro seemed to see her confusion and, unusually, began to explain. "Do you think a swordsman cuts things using only the sharpness of his blade and brute force?"

He recalled his battle in Alabasta against Mr. 1, Daz Bones, the man whose entire body was made of blades, as well as the teachings his master Koushirou had given him during that desperate fight.

"A true swordsman can cut through everything, and can also cut through nothing." His voice became low and magnetic, as if he were speaking a truth that governed the world. "Everything has its own unique 'breath.' Stone has the breath of stone. Steel has the breath of steel. Even a sheet of paper has its own breath."

He extended a finger and lightly touched the iron wall before him.

"What you need to do is not use brute force to contend with its hardness. You need to listen, to sense, to find the rhythm of its 'breath'—to find the 'core' of its existence. As long as you can sense that core, then no matter how sturdy it appears, it will become vulnerable in your eyes."

This mysterious theory, filled with Eastern philosophical undertones, sounded like incomprehensible gibberish to a mage accustomed to thinking in terms of magical formulas and the conservation of energy.

"Listen... to the sound of stone?" Levy was utterly confused, but she still tried her best to understand.

"That's right." Zoro nodded. "Come on, try it. Close your eyes and use your heart to 'listen' to the sound of the land beneath your feet. Feel its pulse."

Half believing, half doubting, Levy closed her eyes. Following Zoro's example, she focused her mind and tried to sense the "breath" of the earth.

However...

One second passed.

Ten seconds passed.

One minute passed.

She did not "hear" anything.

No, it was not that she heard nothing at all. She heard the rustling of wind through the leaves, the shouting and cursing of Natsu and Gray fighting in the distance—"You underwear bastard!" "Shut up, droopy eyes!"—and Happy's cry of "Aye~!"

She just could not hear the pulse of the earth.

"Um... Teacher Zoro..." Levy opened her eyes dejectedly. "I... I don't think I can hear it."

Zoro sighed, wearing an expression that said, "I knew this would happen."

"Tch, I guess it really is too much to ask of you." He shook his head. "Looks like I'll have to use a more direct method to let you experience it."
