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

"So, your current physical body is the result of possession?" Gou An asked.

"No!" The Demon King, Desolate Waste, immediately shook his head in denial: "It's not possession, it's symbiosis!"

"Symbiosis?" This was the first time Gou An had heard this concept, and he was even more curious.

"Yun Yao's current physical body was originally that of a human cultivator who was on the verge of death," the Demon King Huang Ku said slowly. "Yun Yao used herself as a catalyst to merge and intertwine with the other's body, achieving symbiosis."

"So, he has two souls inside him?" Gou An asked again.

"No!" Demon King Huangku shook his head again: "Their souls have also merged together, but Yun Yao is in control."

After hearing this, Gou An opened his mouth as if to say something, but then closed it again.

All he wanted to say was, what's the difference between this and possession?

But fearing that they might anger the Demon King, they could only choose to remain silent.

"Come to think of it!" the Demon King Huangku said slowly, "this current physical body is the third person with whom Yunyao has coexisted."

At this point, the Demon King Huang Ku sighed before continuing, "Yun Yao had never had a headache before, and each symbiosis went very smoothly."

"This time it went smoothly and there were no abnormalities, but the problem arose from the accident more than 30 years ago."

The Demon King Huang Ku's gaze shifted back to Gou An, and he said, "After that great battle, Yun Yao's originally perfectly fused soul was torn apart. I think the problem lies with that human cultivator; he seems to know the owner of the body Yun Yao originally shared."

"If Yun Yao's headache is indeed caused by her deep-seated obsession, then it is because the obsession of the symbiotic being was awakened by that human cultivator from that great war."

After recounting the events, the Demon King Huangku asked Gou An, "After hearing your story, do you have any solutions?"

After hearing what had happened, Gou An was deeply shocked and slowly pieced together all the causes and consequences.

The human cultivator who fought Yun Yao thirty years ago was none other than Shen Yu, the young master of the Blackwater Domain.

Not only did he and Yun Yao suffer heavy losses, but he also awakened the lingering obsessions that had been dormant within this symbiotic body for many years.

Two unfamiliar consciousnesses intertwined and entangled, relentlessly haunting Yun Yao's soul. Over time, this manifested as a recurring, persistent headache.

To be precise, this isn't a headache, but rather two different consciousnesses vying for control of the body.

It's like having a split personality!

Seeing that the Demon King was still waiting for his answer, Gou An had no choice but to say, "To completely cure the headache, we must calm our obsession. Since it was caused by that human cultivator, we must find him to resolve the problem."

But the Demon King shook his head after hearing this: "I told you before, that person was poisoned by Yun Yao, he's probably already dead, how could we possibly find him?"

Although Gou An knew that Shen Yu was not dead, he could not say it directly at this moment.

So he could only say tactfully, "If we can't find the person in person, someone who looks similar will do. Does Your Majesty have a portrait of such a person?"

"A portrait?" The Demon King Huang Ku thought for a moment, then flipped his hand and took out a piece of white cloth, throwing it into the air.

The white cloth automatically unfolded and floated in the air. The next moment, he pointed his finger at the painting, and the image of a young man named Xiu automatically appeared.

Gou An looked at the portrait, and it was nine-tenths similar to the Shen Yu that Gou An had seen.

The only difference is that, although Shen Yu in the portrait is still beautiful, she is much more masculine than she is now.

"This is the person!" The Demon King Huang Ku flicked his finger, and the portrait flew into Gou An's hand: "If you want to cure your headaches, you need to find someone who looks similar. I'll leave this to you."

"Yes!" Gou An accepted the portrait and quickly bowed.

"Furthermore!" the Demon King Huangku added, "Refine more pills to relieve headaches, as her headaches are getting worse."

"Yes!" Gou An nodded again.

The Demon King sighed, then filled a glass cup with bathwater and drank it down.

Gou An took the opportunity to excuse himself and leave.

After leaving, they returned to their own courtyard.

To become the protector of the country, one must first cure the queen's headache.

To cure your headache, you need to find Shen Yu.

But why would Shen Yu, a young master of the Blackwater Domain, come to the City of Ten Thousand Demons?

Judging from their past grievances, coming here would be suicide.

After much thought, Gou An took out the communication jade token that Shen Yu had given him, pondering how to trick him into coming over.

Gou An thought of several excuses, but none of them felt quite right.

His father is the Lord of the Blackwater Domain, a Nascent Soul cultivator. If he were to deceive his son to death, he would definitely fight him to the death.

So in the end, Gou An decided to tell the truth and let him decide for himself whether to come or not.

After all, Shen Yu also wanted to find this female demon named Yun Yao.

Finally, Gou An wrote a short essay of several hundred words on the jade tablet, recounting his discovery of the female demon Yun Yao and informing Shen Yu of her current identity, as well as issues such as the symbiotic headache.

And at the end, he said that the Demon King was looking for someone who looked similar to him, and told the other party that if they wanted to see Yun Yao, now was an opportunity.

After writing down all the contents, Gou An withdrew his finger, and the once smooth jade tablet was now covered with densely packed small characters.

They thought Shen Yu would reply soon, but the jade tablet didn't react at all for a long time.

Just as Gou An had been waiting for a long time, thinking that Shen Yu had chickened out and dared not come, the jade tablet suddenly glowed faintly.

Gou An turned the jade pendant over and saw that words had started to appear on the back of it automatically.

One stroke follows another, as if they are writing the content in sync.

Unlike Gou An's lengthy response, Shen Yu only replied with a few words, concise and to the point.

"Alright. We'll meet at Wanggui Tower in Falling Maple City five days from now."

The writing stopped here, and the inspiration gradually disappeared into the jade tablet, leaving no more words.

Finally, the jade pendant, which was originally full of spiritual energy, became increasingly dull, as if it had run out of energy and turned into an ordinary gray stone.

Seeing this, Gou An probably guessed that this object could only transmit information once, and would turn into a useless stone after the transmission was over.

No wonder Shen Yu told me not to use it casually.

Then a ball of spiritual fire rose in his palm, burning the ash stone in his hand into dust.

Since Shen Yu has made an appointment with me, I can go and meet him.

Even if the other party doesn't come, they can learn more about the past, which will help them come up with a better way to cure Princess Yunyao's headache.

Gou An then took out a map to find the location of Luofeng City, and finally found it in the Eastern Continent.

This is the city closest to the Monster Mountain Range.

Although not large in scale, it is located in the buffer zone between the human and demon realms, a place where all sorts of people mingle and order is lax.

That's why this is the best place for a private meeting.

Gou An did not wait five days before setting off, but instead reported to the Demon King that he was leaving early the next morning.

The excuse was, of course, to go out and find a suitable person, and he even took the opportunity to ask the Demon King for 100,000 spirit stones as travel expenses.
