Phantom Sword of the Dead

Phantom Sword of the Dead (환영사자검) is a one of White's Spirit Sword technique that appears to be an incredibly destructive downward slash.

Hoaqin first materialises a Shinsu aura around the blade of his long sword, and then--with a command "Roar"--launches a lucidly-coloured blast with a wide arc upon slashing.

Notes and Trivia
LINE WEBTOON created confusion between readers because they use different ENGLISH translation for the same technique on two separate chapters, while in fact, the technique has the same Korean Hangul writing (환영사자검) on both Vol.2 Chapter 185 and Vol.2 Chapter 192 on NAVER WEBTOON.
