Skills didn't just exist individually. Just like how Lu Chen's Conqueror's haki could be added to his battle cry, the master level swordsmanship could also greatly enhance his Justice's wrath.
With the combination of several skills, Lu Chen's righteous fury turned into a flaming sword Qi and his attack range was now 140 meters.
The wrath of justice was not the only thing that was linked to him. Lu Chen's Barbarian King's bloodline seemed to be useless against the wrath of justice but one must not forget that both summoning the fire of justice and releasing the sword Qi required stamina and vitality.
If it was a person with insufficient physical strength, even if they had the wrath of justice, they could only shoot out one or two sword auras at most.
On the other hand, Lu Chen's physique was enhanced by the Barbarian King's bloodline. He was able to shoot out nearly 100 sword Qi in a short time. This was the link of the Barbarian King's bloodline.
