Huo Yuhao had previously been untouched by the large-scale remote attack soul guidance devices set up in the Ming Dou Mountain Range mainly because they could not locate him. Otherwise, there would have been no need for Mad Bull Douluo Wang Yiheng to take action himself, as the terrifying barrage of long-range fire would have torn him to shreds long ago. These large remote attack soul guidance devices currently have a maximum attack range of thirty kilometers. Of course, this is without considering fixed soul guidance cannonballs. If fixed soul guidance cannonballs were included, their attack range would be even longer. However, the precondition is that they must first lock onto their target.
