For Supreme Sage Qin Tian and the ancient princes to take action, the only possibility was that they had found some treasure, which led to such a dispute.
Normally, they would not fight for no reason. After all, in this vast cosmic, even having an extreme emperor weapon was not a guarantee against many dangers.
Qin Chen and the others were still moving forward. Then, they sensed that some terrifying traces had been left behind in front. A great battle should've taken place, though they had, unfortunately, found nothing.
Qin Chen could only guess that Supreme Sage Qin Tian or the ancient princes had activated their extreme emperor weapons. Otherwise, such a powerful aura wouldn't have been realized.
He quickly led the group forward, and the corpses of many experts appeared before their eyes. These experts' corpses included those from the ancient races, geniuses from the cosmic, and human cultivators.
