After bringing the witness into his office, he began to ask the witness what he saw that day. When he learned that the witness actually saw Li Zhenghao enter the Death Valley, he felt a chill in his heart. However, judging from the man's performance, he did not discover him that day, but for the sake of safety, he decided to get rid of the man without anyone noticing.

After giving the witness a generous reward and appeasing him, He Ning asked the witness to take him to the scene of the incident to take a closer look. If it was confirmed that what he said was true, he would give him a generous reward.

Under the temptation of material things, the witness naturally agreed. When the two men arrived at the sect gate, they saw Chen Xianzhi still there. It was obvious that he would not give up until he got an explanation.

He Ning's heart moved, and he walked up to Chen Xianzhi and whispered: "We have some clues about this matter, and we are going to investigate it now, but you don't say anything yet. There may be a traitor in our sect. If you don't believe it, you can come with me to investigate."

Chen Xianzhi had no doubts and followed him without hesitation. He knew that the other party was the grand elder of the Wuji Sect and his strength was at the celestial realm. It would only take him a few minutes to deal with him, so there was no need to lie to him.

In order to avoid suspicion, He Ning brought a few elders of the Wuji Sect with him on this trip. However, these people were all his confidants. They were also involved in the previous murder of Li Zhenghao, so he was not afraid of them informing on him.

On the way, Chen Xianzhi also learned from the informant that Li Zhenghao was going to Death Valley, but he did not know how terrible the Death Valley was. As soon as he arrived at the Death Valley, he rushed in, and then followed Li Zhenghao's footsteps and disappeared out of thin air.

The witness realized something was wrong when he saw this and tried to escape but He Ning slashed his neck with a sword.

After returning to Wuji Sect, He Ning and others told the people in the sect that the witness had lied about the situation in order to get a reward, and Chen Xianzhi, who was unaware of the situation, was eager to find the truth, so he broke into the Death Valley before they had a chance to dissuade him.

When he saw that Chen Xianzhi lost his life because of the witness's lies, he killed the man in anger, and the matter was left unresolved.

Later, he supported his own disciple to become the leader of the Wuji Sect and controlled the Wuji Sect behind the scenes.
