Hellfire only harms objects with life force.
Moreover, its power depends on the target's life force strength!
In Bone King Form, Lu Xun has only a level 4 Wither trait.
If Master Dutch were a special-level life form, he could withstand Hellfire with his body, at most getting slightly injured.
But unfortunately, he's a pure Top Up Warrior... and he hasn't even topped up enough.
Even though he possesses Special Level Tier Eight strength, his life level is only low. He was instantly killed by Hellfire to the face.
The second Great Sword Hero of Jinghai was counter-killed by Lu Xun's cross-tier attack. He probably can't die in peace.
But this can't blame Lu Xun for lacking Martial Virtue... it was the other side that cheated first!
He was used to hiding an ace up his sleeve before fights, keeping a trump card just in case, only using it as a last resort.
