From the very beginning, Zhu Wuyan had not killed Zhen Zuonian on purpose.
If Zhen Zuonian hadn't wanted to kill him, Zhu Wuwan wouldn't have killed him. However, he didn't expect that this would become the fuse of the war between the Zhen Clan and the Zhu Clan. Zhen Zuonian was the first Foundation Establishment cultivator to die in the war between the two clans.
Zhu Wuyang really didn't expect this.
As for Zhen Wuying, he had already infiltrated Huoyuan Peak to assassinate and kill people, including Zhu Wuyang. Zhu Wuyang didn't believe that Zhen Wuying wouldn't kill him if he saw him.
If Zhu Wuwan hadn't discovered him first, he might have been discovered by Zhen Wuying. At that time, Zhen Wuying would definitely kill him.
In addition, Zhen Wuying had stolen so many treasures and elixirs, forcing Zhu Wuyang to kill him for the treasures. Therefore, Zhu Wuyang had no choice but to make a move.
