Murdering Blow: Espada de la Luz (살인기 광명의 검, 殺人技 光明剣,Salin-gi Gwangmyeong-ui Geom) is a strong electrical Shinsoo attack and another version of the Maschenny Style: Lightning Spear Technique. The lightning spear is extremely fast and accurate compared to normal Shinsoo techniques and it can be used for short and long range combat. First the electric Shinsoo is formulated into a sword and then the electric sword is flung at the opponent and extends until it hits them. It possesses extreme piercing abilities, however a downside to this technique is that it takes a toll on the user's body.
When Koon Ran used the technique, it was strong enough to pierce through a livingIgnition Weapon in one shot; likewise, it proved capable of stabbing through Anak Zahard, whose power originaly hails from Zahard. However, he claimed that he couldn't use it more than once per battle.
