[Sword of the Blue Sky] A long, slender double-edged sword passed down to the head of the Namgung Clan. The silver-blue blade is engraved with blue lightning patterns, featuring a silver crossguard and a deep blue hilt.

[Sword Style — Blue Sky Thunder-Lightning Sword] Characteristics: A high-speed charging style that pierces through the shortest, straightest path with explosive acceleration to seize the initiative and never let go. It has a higher offensive ratio than other styles, and even its defense is closer to a momentary transition for the next attack. Blue-white lightning erupts with every stroke, followed by delayed thunder.

[Mental Law — Imperial Thunderbolt] Characteristics: Extremely compresses internal energy in the dantian and throughout the body, then explodes it through the legs, waist, and shoulders to create acceleration beyond human limits. Specialized in maintaining seized initiative rather than stopping or retreating.

1st Form: Thunderbolt Flash — From a sheathed position, explodes the power gathered in the legs simultaneously with the draw to erase distance in a straight line and deliver a horizontal slash. Blue-white lightning splits the ground, followed a beat later by thunder and the eruption of wounds.

2nd Form: Blue Sky Piercing — Aligns the sword, arm, and shoulder in a single straight line and advances explosively to pierce the opponent's defensive center. Blue-white lightning condensed at the tip extends like a long spear to penetrate defenses.

3rd Form: Triple Thunder Strike — Seamlessly connects three strikes targeting the upper body, waist, and neck to force a reaction, then aims for an opening with the final blow. Three bolts of lightning flash in succession before merging into a single light.

4th Form: Imperial Smite — Raises the sword above the head and pours the body's full weight and acceleration vertically to crush the opponent's weapon and posture. A thick bolt of blue-white lightning strikes down to the ground along the sword's path.

5th Form: Syncopated Flash — Irregularly repeats momentary explosive acceleration and sudden stops to draw out the opponent's reaction from a distance. Afterimages of broken blue-white flashes appear in multiple directions, hiding the moment the sword will strike.

6th Form: Heavenly Thunder Return — At the moment of impact, flicks the sword shortly and strongly to deflect the opponent's path, then converts that recoil directly into acceleration for the next attack. The colliding lightning reverses direction and returns to the opponent.

7th Form: Ascending Thunder Slash — Lowers the stance to the extreme, then surges up with the explosive power of the legs and waist to slash upward beneath the opponent's defense. A massive pillar of blue-white lightning soars into the sky along the sword's path.

8th Form: Falling Bolt Strike — Flips the body in mid-air after ascending, concentrating the sword tip and body weight on a single point to strike vertically. The condensed lightning explodes at the point of impact, cracking the ground like a spiderweb.

9th Form: Infinite Blue Sky Advance — Without fully retracting the sword, connects thrusts and slashes into the next forward movement to continuously break through multiple enemies. Numerous blue-white lights connect the battlefield like a single lightning path.

10th Form: Imperial Cleaving of Heavenly Thunder — Compresses the body's internal energy and all acceleration into a single, shortest, straightest strike that penetrates the opponent's attack and defense simultaneously. In the moment sound vanishes, only a pure white flash passes, followed by an explosion of sky-shaking thunder as the sword is sheathed.

[Secret Technique — Shadowless Heavenly Thunder Flash] Suppresses all presence and sword intent, then explodes the Imperial Thunderbolt energy in an instant to erase the distance to the blind spot before the opponent can even perceive the draw. A single strike carves through both defense and vitals, initially passing as a silent blue-white flash. The moment the sword is sheathed, lightning explodes along the entire path with delayed thunder, revealing the wounds.
