The feeling Berserker Immortal gave Zhou Wen was like an upgraded version of Zhong Ziya. He was equally crazy and domineering. Although the sword arts were different, the feeling they exuded when using swords was very similar.
Their usage of swords was different from ordinary people's. If one drew the analogy of using swords to driving, the first reaction of ordinary people when they saw a situation ahead would be to slow down; however, they would choose to accelerate and rush over before the route was sealed.
If one's judgment was accurate and fast enough, they could pass through. However, if one made a mistake or if one's speed wasn't fast enough, they would die.
However, Berserker Immortal was an extremely experienced veteran. In a harrowing battle, he could rush over before Zhou Wen could seal off the area. This threw Zhou Wen into an extreme disadvantage.
