"The case of the Skull of Dual Horns is proof that troubles will come to me and escalate into something more. Fortunately, it led me to the devils, but if it had led me to the demon's power, I'd still beat them down if they came my way," Aldrian emphasized.
From another perspective, it might seem like Aldrian was looking for trouble when he killed everyone from the Skull of Dual Horns, but he was simply ensuring there were no loose ends that could harm Yu Fenglian. At the same time, he was also satisfying his own selfish desire to eliminate those thugs.
Even though his encounter with those demonic cultivators was because of Yu Fenglian. In the end, that run-in with Yu Fenglian bore fruit, allowing him to uncover the devils' plot in Dual Horns Peak City. If more demonic cultivators approached him like that, he would gladly entertain them—it was just one way to pass the time, even if they came from a major clan.
