It is the 3rd Level of the J.R.I.R. Crush used by Kim Gu in the Webtoon series, The Boss.[1]

The effects have not been seen but when Tac hit Zhang Fei's spear, there was smoke emanating from it which suggests the skill is extremely powerful.[2]


Tac attemopted to use this skill on Sam Han but it was blocked by Zhang Fei's 1.8 Zhang Long Steel Spear. Smoke was coming from the point Tac's fiist came into contact with the spear.[2]
