I Died and Became a Noble's Heir-Chapter 431: Testing a New Idea

An idea began forming in his mind, fragments of combat experience and magical theory coalescing into something new.

He’d seen archers in the arena, watched them strike from impossible distances. But arrows were physical. Limited by materials, affected by wind and gravity.

But faithful companions weren’t limited by gravity. Lyra was a prime example.

When Jack first fought dragons, an arrow came from nowhere and saved his life. He later found out that Lyra had fired the bow.

And she fired her arrow from the castle, which was a couple of days’ ride away. Lyra was considered legendary with a bow. Her range was all of Eysium.

If you angered her or the king, you would die the moment you stepped outside. 𝚏𝐫𝚎𝗲𝕨𝐞𝐛𝕟𝚘𝐯𝚎𝗹.𝕔𝐨𝗺

Lightning didn’t have those limitations.

What if he could...

"Young master," Loryn’s voice interrupted his thoughts.

Jack’s red eyes opened, fixing on the shadow demon with mild irritation at the interruption.

"Not now, Loryn. I’m working on something."

But the idea had already taken root. Jack stood abruptly, his mind racing with the possibilities. He turned to his fifteen panthers, who had been resting nearby.

"Find the Mistborn," Jack commanded. "Locate them and wait. Don’t engage, mark their positions."

The panthers moved immediately, vanishing into the jungle.

"Young master, I was trying to inform you that..." Loryn began again.

"Stand next to me," Jack interrupted, demanding that he come. "And prepare some dark mana. Don’t release it yet, just have it ready."

Loryn’s confusion was evident in his purple eyes. "May I ask why, young master?"

"I want to try something," Jack replied. "An experiment. I want to see what happens when I combine it with my lightning."

Understanding dawned on Loryn’s features, quickly followed by interest. The shadow demon moved to Jack’s side, dark mana beginning to gather around his hands in wisps of pure darkness.

Kaedor watched from a safe distance, his rings clicking with nervous curiosity. "Master, combining opposing elemental forces is... well, it’s theoretically possible, but the instability..."

"That’s why we’re testing it," Jack said without looking at him. "Theory is worthless without practical application."

Through the Soul Link, one of the panthers projected a clear message:

’Found them. Seven Mistborn gathered near the swamp’s edge. Waiting for your command.’

Jack’s mind calculated the distance. Roughly three hundred meters through dense jungle, multiple obstacles, and targets that could dissolve into mist at any moment.

He raised both hands, assuming a stance like an archer drawing a bow. But instead of physical weapons, red lightning began to materialize.

The bow formed first. Crackling energy taking solid shape through sheer force of will and magical control.

The construct wasn’t just visual mimicry. Jack was creating a functional bow from pure lightning, the string humming with contained energy, the limbs crackling with power that wanted to be released.

Then the arrow, a bolt of concentrated electricity that hummed as he touched it.

"Feed your dark mana into the bow," Jack commanded. "Don’t stop until I tell you."

Loryn hesitated for only a moment before complying, dark mana flowing from his hands into Jack’s lightning construct.

The red lightning bow began to change, darkness spreading across its surface like ink in water.

But it wasn’t consumption; they were fusing. The bow turned black as night, but red lightning coursed through it like veins of molten energy, visible beneath the dark surface.

The arrow transformed as well, outlined in pure darkness while its core blazed with red electrical power.

Kaedor took an involuntary step backward, his merchant’s instincts screaming danger at the sight of the impossible weapon. "Master, that’s... that energy signature is volatile. If it detonates before release..."

"It won’t," Jack said with absolute certainty.

His control over the lightning was perfect, the fusion with Loryn’s dark mana creating something greater than the sum of its parts.

The darkness provided structure and penetration capability, while the lightning offered devastating kinetic force and energy discharge.

Jack’s red eyes narrowed as he aimed through the jungle toward where his panthers had marked the Mistborn. Three hundred meters. Seven targets clustered together. One shot.

He could feel the power thrumming in his hands, the arrow eager to be released, the bow straining against the tension.

His Prince of Thunder class resonated with the construct, recognizing it as an extension of his will and magical prowess.

He released his fingers, and the arrow shot forward.

The arrow tore through the jungle like a spear of darkness and lightning combined. Trees exploded as it passed, bark and wood disintegrating from the sheer energy. The darkness devoured obstacles while the lightning provided devastating kinetic force.

The sound was deafening. A crack of thunder combined with something darker, like reality itself was being torn.

Three hundred meters crossed in less than a second.

The arrow struck the first Mistborn dead center, punching through its glowing core before the creature could even register the threat.

But the arrow didn’t stop. It continued forward, the dark mana allowing it to phase through the dissolving fog of the first target and strike the second.

Then the third.

Fourth.

Fifth.

Sixth.

The seventh Mistborn tried to dissolve, to escape into pure mist form. But the darkness in the arrow adapted, spreading through the fog like corruption, following the creature’s essence until it found and destroyed the core.

Seven targets eliminated with one arrow.

Through the Soul Link, Jack felt his panthers’ shock and awe at what they’d witnessed.

The arrow had carved a path of destruction through three hundred meters of jungle, eliminated seven targets that should have been able to escape, and finally dissipated only after achieving complete success.

[7 Mistborn (Dread-rank) eliminated - 3,500 Death Tokens acquired]

Jack lowered his hands slowly, a smirk forming behind his visor. The skill had worked better than he’d hoped. The combination of his lightning with Loryn’s dark mana had created something uniquely devastating.

"Stop the mana flow," Jack said calmly.

Loryn complied, the dark energy ceasing immediately. The shadow demon stared at the path of destruction through the jungle, his purple eyes wide with something approaching disbelief.

"That was..." Loryn searched for words.

Kaedor had gone completely silent, his usual commentary dying in his throat as he processed what he’d just witnessed.

Finally, he managed to speak:

"Master, do you understand what you just created? That arrow didn’t just pierce through targets; it adapted mid-flight. The dark mana component was intelligent, following the Mistborn’s essence even when they tried to disperse."

His rings clicked frantically as his analytical mind worked through the implications.

"If you could replicate this consistently, if you could standardize the technique... Young master, this could be the foundation for an entirely new school of magic. Fusion techniques between opposing elements aren’t just rare. They’re considered theoretically impossible by most magical scholars."

Jack’s smirk widened. His mind was already at work on refinements, variations, and ways to improve and expand the technique.

This could be the foundation for his fourth skill. A ranged devastation tool that could strike from impossible distances with lethal precision.

Jack raised his hands again, red lightning beginning to form into another bow. Through the Soul Link, he felt his panthers marking more Mistborn positions across the swamp.

Eighty-six Mistborn remained. And he had just proven he could kill seven with a single shot.

"Keep the dark mana ready, Loryn," Jack commanded, his voice carrying cold satisfaction. "We’re not done yet."

He pulled back another arrow of fused darkness and lightning.
