The Untamed Episode 21

The two YunMeng siblings and Nie HuaiSang share a heartfelt reunion with Wei WuXian. However, something about him doesn't seem right. In the Nightless City, Wen RuoHan learns of Wen Chao's death. Back in the Unclean Realm, the representatives of each sect come together to celebrate Wei WuXian's return. But some cultivators openly insult the fact that he lacks his sword and discusses his weird way of killing Wen Chao. Halfway through the dinner, Wei WuXian leaves to drink his wine alone and Jiang Cheng follows. Jiang Cheng asks why he doesn't have his sword but Wei WuXian simply replies that he doesn't want to. That night, he practices his demonic energy and Jiang YanLi enters the room after. She asks for the name of Wei WuXian's new flute and the latter names it "Chen Qing". In the Nightless City again, Wen RuoHan uses the Stygian Iron pieces to create puppets. The next day, Jiang Cheng is unable to find Wei WuXian for the sect meeting. Jiang YanLi then finds him using his flute on the mountain, which affects the group of Wen Sect below. When she confronts him, Wei WuXian lies that it was the wind. Wei WuXian shows up to the meeting midway, only to leave again. After, Lan WangJi wishes to look for Wei WuXian but decides against it. Jiang YanLi spots him and begins to ask about Wei WuXian. When the latter finds them, he gets mad at Lan WangJi for spilling the beans to his sister but it has been a misunderstanding. While Wei WuXian rushes to apologize to Lan WangJi, the two fights and Lan WangJi asks where his sword is. (Source: Wikipedia)
