The battlefield around those two sects was literally taking fire. After the elders saw their sect masters killing each other, they went crazy and bared their fangs against their opponents, battling until death. The hatred between those two sects fueled their fight until the last man standing, a badly injured Dark Flame Sect Elder that wouldn't resist much longer.
On another front of this huge battlefield, Zhao Yaozu led four of the strongest Zhao family elders in a struggle against the Tao family. Zhao Yaozu was a Mana Perception middle-stage cultivator, while the elders of his family were all Qi Transformation peak-stage practitioners.
The Tao family was fighting with only three people right now, since Tao Zhong and Tao Changming hadn't showed up until now. Tao Shing was a Mana Perception middle-stage cultivator and his two companions were at the Mana Perception initial-stage realm.
