Ch. 21The Shame of a Rebellious Disciple, the Poison of Martial Souls
Bibi Dong apologized after Lu Xuan stopped her from kissing him, then reported that the Mingluo Nether Spider Lotus had strengthened her martial souls and granted her venom that could affect other martial souls. Lu Xuan tested the venom safely, explained his poison-resistant constitution, and received a medical canon from his system, only to discover that Sword Douluo Chen Xin had occupied one of his disciple slots.
- Bibi Dong blushed with shame after Lu Xuan moved her aside and scolded her for disrespecting her teacher.
- Viewers across the continent reacted to the near-kiss, while Chen Xin praised Lu Xuan and Gu Rong mocked him for being single.
- Bibi Dong told Lu Xuan that the Mingluo Nether Spider Lotus had raised her soul power, removed the conflict between her martial souls, and given her venom that could harm martial souls.
- Lu Xuan let Bibi Dong test her Soul-Devouring Spider Emperor venom on him, then explained that the Star Anise Mysterious Ice Grass and Blazing Apricot Delicate Herb had made him immune to poison.
- Tang San regretted that Lu Xuan had already consumed the two precious immortal herbs, while Bibi Dong hoped Chrysanthemum Douluo and Ghost Douluo would find herbs for her.
- Lu Xuan claimed his Hundred Flowers Canon reward and discovered that Sword Douluo Chen Xin had taken one of his disciple slots.
