Netherworld Purgatory!
The "Princess Youl Ling" mentioned by Ghost General Gui Rao is none other than Shi Feng's sister, Shi Ling.
After learning that her brother Shi Feng had a name in the Netherworld, Shi Ling also gave herself a name there, calling herself Youl Ling.
Shi Ling donned a light blue dress, her thousand strands of hair dancing in the wind. After hearing Gui Rao's words, she nodded with determination and replied:
"Last night, I had a dream where I saw my brother facing peril. I need to find him. Maybe he needs me right now!"
"Princess, you might be overthinking! The Great Emperor is far beyond our imagination in strength; he will surely be safe."
Beside Shi Ling, Ghost General Gui Huan also spoke.
Upon hearing Gui Huan's words, Shi Ling insisted, "No matter what, I have to go to the Wilderness Continent."
