During that time, many of them had learned to use Impact Arrow with multiple arrows, and some had even mastered it with four or five. Combined with the Impact Arrows unleashed by the other Nine Nether Nether Soldiers, their attacks had grown much stronger, posing a considerable threat to Chi Xue and the others—especially since they hadn't yet made use of the grand formation.
