The Vice Palace Master of the Divine Sword Palace had a close relationship with Liu Wen. She was essentially a mother figure to him. Tang Yin found out about this when he searched through Liu Wen's memories.
It was no surprise that she lost control of her emotions when Liu Wen did not return from the Exotic Enclosure Region.
The Divine Sword Palace also lost its heir. This was an extremely large blow to the organization, after all, finding another cultivator with a Cultivation Physique was almost impossible. Not to mention, it had to be something specific to swords like the Profound Nine Sword Physique which was even more difficult to find.
Even if the Divine Sword Palace found a cultivator with a Cultivation Physique, they would not be able to nurture them into a powerful figure due to their inheritance strictly pertaining to the Dao of the Sword.
Once the Divine Sword Palace flew off, the 28 disciples and Tang Yin let out collective sighs of relief.
