Wei WuXian wants to investigate the back mountains but Lan WangJi pulls him to the Library Pavilion for his punishment. Wei WuXian gets bored of copying passages and decides to apologise to Lan WangJi by justifying his actions from that night. However, Lan WangJi finds him a bother and shuts him up with the silencing spell again. In the room of the Wen siblings, Wen Ning expresses concern over his sister's constant disappearance. But Wen Qing instead laments over her inability to cure Wen Ning's illness despite being a physician. Back in the Library Pavilion, Wei WuXian finally finishes the punishment and gives Lan WangJi a drawing of his portrait as a farewell gift from supervising him. However, it was drawn femininely as a prank. Wei WuXian then replaces Lan WangJi's book with an erotic art book, causing Lan WangJi to tear it apart with anger and tells him to leave. When Wei WuXian, Jiang Cheng and Nie HuaiSang are hanging out, they spot a magical owl that is used by the Wen sect for spying and this raises questions among themselves. On the other hand, Lan WangJi and Lan XiChen learns of the unusual appearance of water ghouls in CaiYi Town and decides to visit the next day. Wei WuXian, Jiang Cheng and the Wen siblings also tag along. While the group scouts Biling Lake for water ghouls, Wei WuXian discovers one hiding below Lan WangJi's boat, causing Lan XiChen to be impressed by his wits. However, the water ghouls form a Waterborne Abyss and the disciples hurriedly flies up to safety. Seeing that Wen Ning is still trapped on the boat with Su She, Wei WuXian comes to help but sees that Wen Ning's eyes has gone all white. He loses balance from the shock and Lan WangJi saves all three of them from the capsizing boat. Back in the Wen siblings' room, Wei WuXian is concerned about Wen Ning. (Source: Wikipedia)
