Zhao Xin's life was extremely similar to Ye Mo's. So, Ye Mo decided to give him a little help. At the very least, he would help Zhao Xin regain his confidence and pride. Zhao Xin had an excellent talent for cultivation. That shouldn't go to waste.
After leaving the Divine Treasure Guild, Ye Mo returned to the Asura Palace, preparing to extract the Divine Dew.
He returned to his room and shut the door. After sitting cross-legged, he took out the Shadowdemon Sky Severing Blade. He didn't intend to let Hong Ling devour the dagger. Instead, he was planning to give it to Nangong Yurou so she could protect herself. But as for the sheath, he'd be extracting the Divine Dew from it.
"Hong Ling, how should I extract the Divine Dew?" Ye Mo asked.
"Take your cauldron out," Hong Ling said. "Try burning the sheath in the cauldron. You'll know what to do after that."
