What episode is Wei Wuxian's swearing-in meeting?

Hundreds of immortals held a swearing-in meeting in the city that never sleeps, crusaded against the ancestors of Yiling, and smashed the Wen brothers and sisters. Wei Wuxian came out to argue with them and was killed by a sneak attack. He pulled out the arrow and wiped the blood from it.

Because his blood can attract ghosts, he didn't want to kill anyone, just wanted to give him an arrow in return, but others didn't understand him and said he was crazy. Finally, this man's younger brother attacked Wei Wuxian, killed the teacher elder sister by mistake, and Wei Wuxian also completely collapsed.

Plot introduction:

Wei Wuxian quietly came to Jinlintai, and when he saw the thin back of his senior, he dared not say anything, let alone go forward. Old lady Jin stayed in the mourning hall with Jiang wearily. The pain of losing her child aged her a lot overnight. She staggered out of the door, looking for something to eat for Jiang, who was tired and haggard. Unexpectedly, she saw Wei Wuxian hiding in the dark.

Jiang couldn't bear to leave and rushed out with him. She was in tears, but she didn't blame Wei Wuxian. She just cried her eyes out. Mrs. Kim collapsed and shouted. Wei Wuxian's eyes filled with tears, so he had to leave despondently. He came to the Woods and was surrounded by the black gas from Yin, which disturbed his thoughts. Wei Wuxian is almost crazy and difficult to control.
