Upon hearing Ye Feng's words, Lin Feifei was utterly shocked.

Lord Luo actually possesses such a rare treasure as Wood Spirit Essence?

He was even willing to use the money to treat his daughter!

This is simply... Lin Feifei was so excited that she didn't know what to say for a moment.

"Hurry up and get me some paper and pen, don't dawdle," Ye Feng said.

Lin Feifei finally came to her senses and quickly grabbed paper and pen, handing them to Ye Feng.

Holding a charcoal pencil, Ye Feng wrote a prescription quickly and swiftly.

"Just get the medicine ready tomorrow according to this prescription. You don't need to prepare two portions; one is enough," Ye Feng said.

"Thank you very much, Lord Luo," Lin Feifei said gratefully as she accepted the prescription.

"Once you have prepared the medicinal herbs tomorrow, I will start the alchemy process for your daughter," Ye Feng said again.

Then, Ye Feng prepared to leave.

But before Ye Feng could leave Cheng Nannan's room, he suddenly stopped, and his expression became very serious.

Because Ye Feng clearly saw a maid open a cabinet against the wall and carefully take out an exquisite headband, preparing to put it on Cheng Nannan.

"Wait a minute, what's that?" Ye Feng asked, pointing to the headband in the maid's hand.

The maid was so frightened that she stood there motionless. Lin Feifei quickly explained, "Lord Luo, this is a spiritual artifact called the Tranquilizing Headband."

"A headband for calming the nerves?" Ye Feng asked, frowning.

Lin Feifei said with a wry smile, "My daughter is in constant pain because of the burns on her body, and the pain worsens at night. As a result, my daughter used to be unable to get proper rest and would often wake up in the middle of the night in pain."

"Three years ago, a mysterious senior who was passing by suddenly visited me. He said he had heard about my daughter's situation and felt deep sympathy for her, so he gave me this calming headband."

"After my daughter put on this calming headband, she was finally able to sleep peacefully without being affected by the pain."

Ye Feng thought for a moment and said, "Let me see this calming headband."

Lin Feifei immediately gave the maid a look, and the maid came over and respectfully handed the calming headband to Ye Feng.

Ye Feng took the calming headband and immediately infused it with his inner energy to examine it.

Before long, Ye Feng had thoroughly investigated and discovered all the hidden tricks within this calming headband.

The calming headband doesn't actually have any calming effect; instead, it's a connector that links to the dream world!

By wearing the calming headband, the wearer's consciousness will enter a deep sleep and connect with the dream world.

This leads to two possibilities.

The first scenario is that the dream world is in an open state, so the wearer can successfully connect to the dream world through this calming headband and enter the dream world.

The second possibility is that the dream world is closed, so the wearer cannot successfully connect to the dream world through the calming headband and is instead in a dazed state.

Regardless of the situation, it can effectively avoid physical pain, thus giving Lin Feifei's daughter, Cheng Nannan, a brief period of peace.

This is why Cheng Nannan appeared in the dream world, and also why she was able to rest and sleep normally after wearing this headband!

Cheng Nannan is not a member of the Eternal Dream; she merely entered the dream world created by the Eternal Dream through this magical artifact!

Now, all of Ye Feng's doubts were resolved.

There is no problem with Nanhua City, and there is no problem with the Nanhua City Lord's Mansion either.

Lin Feifei did not collude with Eternal Dream, and her daughter Cheng Nannan is not a member of Eternal Dream.

Night Breeze returned the calming headband to the maid and said with a smile, "Put it on her."

"Yes, Lord Luo."

The maid nodded and went over to put the calming headband on Cheng Nannan's head.

The spirit stone in the center of the calming headband immediately emitted a faint glow, and a hint of drowsiness appeared on Cheng Nannan's face.

"I...I want to sleep now, Uncle Luo," Cheng Nannan said.

"Okay, see you tomorrow. Sweet dreams," Night Breeze said with a smile.

Then Ye Feng gave Lin Feifei a look.

Lin Feifei immediately followed Ye Feng away from there and returned to the study.

The assassin's body in the study had been disposed of; no trace was left at the scene.

But this was a minor matter, and Ye Feng didn't pay it any mind. He closed the study door and said, "That calming headband is a spiritual artifact crafted by the people of Eternal Dreamland."

"What!"

Lin Feifei was taken aback.

Night Wind said earnestly, "Eternal Dreamland relies on dreams to create a dream world called Dream World. This is not the dream of any one person, but a collection of the dreams of hundreds or thousands of people."

"The reason why that calming headband was able to allow your daughter to sleep peacefully and no longer be affected by the pain is because after wearing the calming headband, your daughter's consciousness entered a dream world, so she could not feel the pain in her body for the time being."

Lin Feifei said in shock, "No wonder my daughter said that she often had dreams after wearing the calming headband, and met many interesting people in her dreams. I never thought it was like this!"

At this point, Lin Feifei hurriedly walked towards the study door.

"What are you going to do?" Night Wind asked.

"Needless to say, of course, it's about making my daughter stop using the calming headband!" Lin Feifei said emphatically.

“But if you stop using the calming headband now, your daughter will be affected by pain again, and even sleep will become a luxury for her,” Night Wind said earnestly.

“But… how can I let my daughter get involved with the people from Eternal Dream? The people from that evil sect, Eternal Dream, are all lunatics!” Lin Feifei said without hesitation.

Night Breeze smiled and said, "But I don't think they have any ill intentions towards your daughter."

After a pause, Ye Feng continued, "Your daughter has been using the Tranquility Headband for three years now. If the people of Eternal Dreamland really wanted to harm your daughter, she would have been dead long ago. But now, your daughter is still alive and well, and with the help of the Tranquility Headband, her condition is much better than before, isn't that right?"

"But...but..."

Lin Feifei wanted to say something, but she couldn't get the words out.

Night Wind said meaningfully, "No matter who it is, you can't define them as simply good or bad, because people's hearts are complex. As for the people of Eternal Dream, they gave your daughter this calming headband. Regardless of their initial purpose, since your daughter was not harmed by it and actually benefited from it, then this is a good thing."

"Moreover, your daughter will not be able to leave the headband until her injuries are fully healed. That's a fact, and you can't change it."
