The Ice Phoenix carriage arrived at the cliff outside the city of Yemo.

Xu Chen and Qingyin got off the carriage, and the other passing monsters and demons, upon seeing the carriage and its imposing presence, dared not approach, no matter how beautiful the women inside might be. Xu Chen pulled Qingyin towards the edge of the cliff, and as she looked out, the sea of fire, the huge copper columns, and the countless servants and suffering mortals all shocked her to the core. After all, she herself was a mortal and unlike the monsters in the demonic realm. Perhaps they saw these scenes as commonplace, but Qingyin could not.

However, after searching for a long time and carefully examining every copper column, they did not find Izayoi.

"Xu Chen, are you sure you saw her!?"

"Qingyin Sister! How could I be mistaken?! It was that copper column! I remember where she carved it!" Xu Chen confirmed.

"It's possible that they moved her. After all, they work here every day. Maybe she's in a place we can't see..." Qingyin looked at the wooden frame of the copper column where several other girls of similar age to Izayoi were carving, and she could imagine how lonely and forced her labor must have been for the past few centuries. She couldn't help but feel a pang of sorrow. "Izayoi, little sister... Xu Chen, let's wait here."

"Yes!" Xu Chen nodded. After all, although Qingyin and Izayoi often argued when they met, their sisterly bond was deep, and Xu Chen understood that completely.

"Qingyin Sister, Izayoi is in Mengyan Kingdom. She's really pitiful. How can we rescue her?" Xu Chen asked.

Qingyin remained silent for a long time before speaking. "Xu Chen, Mengyan Kingdom is the biggest secret of the demonic realm. Even I, who have been here for hundreds of years, must never touch that taboo. I don't know much more about it than you or most ordinary creatures in the demonic realm. Right now, I have no idea how to enter Mengyan Kingdom."

"What... You... Qingyin Sister, you've been here for centuries and you still don't know? Then how do we save Izayoi?"

"Well, Xu Chen, don't worry. I didn't deliberately inquire about this before. My master Xizun might know something." Qingyin said.

"Really!" Xu Chen's face showed a glimmer of hope, but then she was suddenly startled. "Master? Qingyin Sister, what do you mean by master?"

"Oh no, Xu Chen, you've misunderstood. When I say master, it's similar to the meaning of lord. I am loyal to Xizun and am considered one of his subordinates. That's all." Qingyin explained.

"Oh..." Although Xu Chen understood, she felt somewhat depressed. After all, hearing the usually aloof Qingyin suddenly call someone else her master made Xu Chen feel uncomfortable.

Just then, a female demon suddenly spoke up. "Lady Palace Master! Xizun has summoned you. He wants you to return to see him immediately!"

"What?!" Qingyin's delicate body trembled. "How could this be? Wasn't I supposed to handle official duties outside? Besides, I have a sound transmission pearl. Why wouldn't Xizun directly contact me with it?"

"I don't know about this, Madam." The female demon replied honestly.

Qingyin looked worriedly at the copper column and said in a somewhat distant manner, "Xu Chen, I must return to Xizun's palace immediately. You should come with me! After all, you have already sworn loyalty to Lord Xizun. He knows about these oaths! And it's not safe for you to be here alone. We can discuss our next strategy on the way."

"But... I want to see Izayoi again..."

"I do too. Izayoi is also my dear sister! But... there are many things I need to tell you on our way. We must return to Xizun's palace immediately!" Qingyin said urgently.

Xu Chen understood Qingyin very well. If she said this, she must have her reasons!

"I understand!" Since they couldn't save Izayoi here, it was better to listen to Qingyin's arrangements and discuss the next steps on the way.

So Xu Chen and Qingyin quickly got back on the carriage and took off.
