Starting as a stray dog, I embarked on a journey of cultivation.

There is no permanent green space.

Princess Yunyao nestled in the arms of Demon King Huangku, her brows furrowed and her face showing weakness due to a severe headache.

Gou An presented the newly refined pills, and the Demon King Huang Ku personally picked one up and fed it to Yun Yao.

After swallowing the pill, Yun Yao, who had been trembling all over from the pain, sighed softly, as if the pain had lessened considerably, and her tightly furrowed brows slowly relaxed.

"How do you feel?" the Demon King Huangku asked softly.

"Your Majesty, it seems to be getting better," Yun Yao replied gently, rubbing her temples.

"That's good!" Demon King Huang Ku nodded in satisfaction when he saw that the pill was effective.

He then turned to Gou An and said, "Hall Master Gou, this time the pills are quite good. I wonder how long it will take to fully recover?"

"Your Majesty!" Gou An bowed and said, "This pill can only temporarily relieve the pain; it cannot completely cure the problem."

"I cannot bear to see my beloved consort suffer such pain. I demand a complete cure!" The Demon King Huangku said resolutely, his attitude firm.

"To completely cure the illness, we need to find the cause!" Gou An patiently replied, "Based on my analysis over this period of time, the cause of the princess's illness is neither physical nor spiritual, but rather mental."

"Spirit?" The Demon King, Desolate Wasteland, frowned immediately. "What do you mean by that?"

"I'm afraid the princess has a deep-seated obsession that she hasn't resolved, and just thinking about it causes her headaches," Gou An said, offering his guess. He continued, "To completely cure it, pills alone won't be enough. We need to find out what the obsession is and then resolve it."

Upon hearing this, the Demon King Huang Ku frowned slightly. He looked at Gou An and then at Yun Yao in his arms, seemingly lost in thought.

"I understand, you may leave now." The Demon King waved his hand, as if he had something on his mind: "I'll summon you again if needed."

Seeing this, Gou An knew he had probably guessed correctly, so he slowly withdrew from the green space and returned to the Demon King's Palace.

Princess Yunyao has been imprisoned by the Demon King in the Wuheng Green Land, a place that appears to be an independent space created by some kind of formation.

It wasn't so much that she was protected inside, but rather that she was under house arrest inside, never having come out even once.

Perhaps this is related to Princess Yun Yao's obsession.

Anyone who is locked up in one place and never released will inevitably develop some form of mental illness.

Not everyone can be like Sun Wukong, who was imprisoned for five hundred years without freedom and still managed to remain sunny and cheerful after being released.

Gou An returned to his residence, preparing to await the next summons from the Demon King.

As soon as I entered the alchemy room, I saw Pig Old Nine studying several booklets of alchemy formulas that Gou An had placed on the table.

"What are you looking at?" Gou An asked casually.

Upon seeing Gou An return, Pig Ninth hurriedly approached him with a grin and said, "Master, I have a favor to ask of you."

"What, you want to learn alchemy?" Gou An asked with a smile.

"No, not exactly!" Pig Ninth scratched his head and chuckled, "I want to ask the Dao Master for a few pills."

"Alright!" Gou An wasn't stingy, but asked, "Do you want a Qi-replenishing pill or a Qi-gathering pill?"

"Neither!" Pig Ninth shook his head, looking embarrassed.

"What kind of pill is that?" Gou An frowned immediately.

"I just saw a Tiger Wolf Pill on that booklet, it looks pretty good!" Pig Ninth licked his lips and said, "So I'd like to ask the Dao Master for a few to try."

"Do you know what this pill is for?" Gou An almost laughed out of anger when he heard this.

"I know, isn't it just that consuming energy makes them as ravenous as wolves?" Pig Ninth sighed, "These demon servants in our manor are too difficult to manage; I don't even have enough energy to keep up with them."

Gou An's lips twitched; he didn't even want to expose the kid.

When he first came out of the Palm Heaven Diagram, he was plump and strong.

The results came out during this period, and I've lost a lot of weight, which means I've been burning a lot of calories every day.

"Go ask other alchemists for help!" Gou An rolled his eyes at Pig Old Nine and scolded irritably, "This master is so busy with affairs of state, where would I find the time to refine this kind of stuff for you?"

"I was wrong!" Seeing that Gou An was angry, Pig Ninth quickly slipped out.

Gou An thought the Demon King would wait a while before summoning him, but to his surprise, only two days later, the white crane came to inform him that the Demon King had summoned him.

So Gou An had no choice but to follow the white crane to the Demon King's palace and meet the Demon King alone.

When Gou An entered, he discovered that it was the Demon King's bathhouse.

At this moment, the Demon King Huangku was soaking in the hot spring, with only his neck and head showing, looking completely relaxed.

"Your Majesty!" Gou An stepped forward and bowed.

Hearing the sound, the Demon King Huangku opened his eyes and slowly said, "Would you like to take a soak too?"

Gou An coughed a few times in fright and quickly refused, "Your Majesty, I am naturally afraid of water, so I'd better not."

"Then find a place to sit!" The Demon King closed his eyes again, enjoying the soothing warmth of the hot spring.

Gou An moved a small stool from the side and sat down obediently. After sniffing the air, he realized that this hot spring was not ordinary hot water.

The taste was like a nutrient solution infused with many spiritual materials, and Gou An also noticed that the entire bathhouse floor was inlaid with spirit stones, the lowest quality of which looked to be mid-grade, and even the bottom of the hot spring was made of spirit stones.

That is why the room is filled with an unusually rich spiritual energy.

"Why did I summon you?" the Demon King asked calmly.

"It must be about the princess," Gou An guessed.

The Demon King Huangku nodded and said, "I summoned you here indeed for this matter."

He opened his eyes again, conjured a glass cup with a flick of his wrist, filled it with bathwater, and took a sip, startling Gou An.

After carefully tasting his own bathwater, the Demon King continued, "Your analysis a few days ago was quite correct. Yun Yao does indeed have a deep-seated obsession that remains unresolved, and her headaches are most likely due to that."

"What exactly is this obsession?" Gou An asked in a low voice.

"I don't really know the specifics either!" The Demon King shook his head and said, "It's mainly because Yun Yao's current physical body isn't his own."

"Huh?" Gou An frowned immediately.

The Demon King smiled, ignoring Gou An's surprise, and instead asked, "Do you know what form I have taken?"

"I don't know!" Gou An immediately shook his head after hearing this: "Your Majesty's transformation is perfect, and you cannot see your original form."

"I..." The Demon King Huang Ku raised his right hand as he spoke, and the next second his palm turned into a twisting tree branch: "It is the form of an ancient tree that has existed for ten thousand years."

"A tree!" Gou An swallowed hard, completely surprised that the Demon King of Ten Thousand Demon City was actually a tree in disguise.

"And Yunyao was a little mushroom that grew under my tree back then!" The Demon King Huangku said, seemingly recalling fond memories of the past, a faint smile on his lips.

Gou An dared not disturb the Demon King's recollection and could only listen quietly.

"Normally, a little mushroom like her has a very short lifespan. She couldn't possibly attain enlightenment on her own. It was I who slowly nurtured her with demonic power for hundreds of years before she successfully transformed into a demon!"

At this point, the Demon King Huangku shook his head helplessly: "It's a pity that even after she takes human form, her lifespan is not long, so she needs to coexist with other people's bodies in order to continue to live."
