Chapter 37: Limit Break

This blob of living mercury possessed three abilities.

The first was an extraordinarily high resistance to magic, an alchemical miracle born from the labs of Alkhemia. It was absurd enough that even a paladin's Sacred Slash barely left a mark. The second was its instinct to devour what it saw, inherited from its slime ancestry, though now limited only to metals rather than flesh.

And the third, the most valuable ability, granted by Ambrose himself at great cost, was its new soulbound talent: Shapeshifting.

The living mercury was all but an infant, new to the world and unskilled in wielding its gifts. All it could do was imitate what it saw.

As such, by mimicking the paladin's form, it transformed into a vaguely humanoid figure of gleaming mercury, roughly similar in outline but with indistinct details. It looked like a half-melted wax statue version of the paladin.

Still, crude or not, its imitation of the paladin's movements was unnervingly precise.

The living mercury swung its sword in a mirrored Sacred Slash. There was no holy light, only sheer mass and momentum—but the blow was powerful enough to make the armored paladin stagger two steps back.

Pressing the advantage, the mercury repeated the same strike again and again, fast as lightning.

But the paladin had already adapted. Twisting his wrist, he caught the next blow along the blade of his sword, deftly dissipating the force. Then, with a sharp turn, he countered. The blade cut deep into the living mercury's head, splitting it cleanly in two.

The strike would have ended a man, but for the living mercury, it was a mere inconvenience.

The split halves of its head flowed together and solidified, trapping the paladin's sword inside its liquid body. Then, copying his motion, the creature spun and slashed back toward his helm.

But before the blow could land, a golden radiance flared around the paladin's head: Aegis of Faith, a divine ward born of unshakable devotion. It could block all sorts of attacks.

The mercury blade skidded off the light as if off a patch of ice, leaving the creature off-balance.

The paladin seized the opportunity to strike. His sword danced in a blur, carving the mercury slime apart until it lost all human shape.

The living mercury had been utterly outmatched in a single exchange. Its lack of technique showed.

Yet as the paladin stepped back to recover, the mangled metal began to flow again. Within seconds, the living mercury stood once more, copying the paladin's latest techniques flawlessly.

Ambrose, watching through a scrying orb, was very pleased by this development.

He had tuned the living mercury's soul by hand to ensure that its shapeshifting was paired with the ability to perfectly imitate what it saw. From how well it could mirror the paladin's attacks, it was clear that Ambrose's work had paid off.

Still, imitation alone was not enough. The paladin's swordsmanship, honed by faith and discipline, was leagues beyond what the slime could manage.

As naive as the paladin remained in matters pertaining to adventuring, his swordsmanship was on the level of a grandmaster.

Their blades clashed again and again. Despite the very same strikes, the very same timing, every exchange ended with the paladin's blade sinking into the living mercury's body while his own armor remained unscathed.

Even when their swordplay mirrored one another perfectly, subtle differences in angle, weight, and tempo left the duel one-sided. If not for the living mercury's ability to regenerate, it would already have been cut up into a dozen pieces.

And the paladin quickly discerned its flaw. The creature might be able to mimic his movements, but it couldn't really think. It couldn't tell a feint from a follow-up. It couldn't innovate or predict his actions.

Thus made confident, the paladin eased his pace, turning the battle into a live exercise.

He stopped using his divine techniques, conserving his holy energy for what he knew was the real threat: the lich watching from beyond the walls.

There was no point wasting strength on a puppet when the puppeteer still waited.

So the paladin stayed on the defensive, testing, waiting, letting the creature burn through its reserves.

He knew regeneration and transformation both cost energy, energy derived from digested metal. Eventually, it would run out.

And when it did, he would end it with a single strike.

Ambrose couldn't help but admire him. "The paladins of the Lyon Empire truly live up to their reputation," he murmured. "The continent's strongest empire indeed."

But admiration didn't pay the bills.

If his prototype were to lose, the footage from his memory crystal would be useless for business. Editing out a defeat was such a hassle.

He had no choice but to intervene. Through the iron door, he whispered, "Silly child, don't let your humanoid form restrict yourself. Why do you only wield one sword? You can have as many arms as you like! Shapeshifting is meant for imagination, not mere imitation!"

The words were a revelation. The living mercury paused mid-regeneration. Instead of sealing its split head, the two halves stretched outward, lengthening into twin rapiers that shot straight toward the paladin's face.

The technique was the same—but now there were two blades coming at impossible angles. The paladin barely reacted in time, his steady tempo shattered.

He managed to deflect both and countered with a brutal pommel strike that dented the creature's chest, but it was already too late.

The living mercury had been freed from its shackles.

In human form, it might not be able to rival the paladin's swordsmanship, but who said it had to be human at all?

Its liquid body twisted and expanded, sprouting arms and blades by the dozen. Like a spinning windmill of silver, it whirled forward, slashing from every direction.

The paladin felt as if a squadron of his comrades had turned on him at once, all wielding the same flawless swordplay, all striking in perfect sync.

The problem wasn't where the next strike would come from. It was that there were too many swords to block.
