The Hehuan Sect cultivates alchemy; my senior sister helps me refine alchemy throughout the world.

Ao Ling'er, Ao Ying's eldest sister, failed to ascend to immortality more than fifty years ago and was never seen again.

Shen Yifei knew that it wasn't a failed tribulation at all, but rather that he had been taken away by the people of the Immortal Punishment. As for where he went, no one knew.

"Can I open this thing and take a look?" Shen Yifei asked.

Ao Ting hesitated for a moment, but still nodded.

Shen Yifei lifted the lid of the box, inside was a jade hairpin. He reached out and took the jade hairpin out of the box.

The hairpin head is carved with a lifelike lotus flower, and a blue bead the size of a grain of rice is embedded in the center of the lotus.

He looked at it over and over again, and suddenly, he felt a very faint fluctuation coming from the blue bead in the small vortex in his dantian.

The fluctuation was very subtle; if he hadn't just absorbed Ao Ying's dragon essence, he wouldn't have been able to detect it at all.

"Strange..." Shen Yifei frowned.

"Second brother-in-law, what's wrong?"

Shen Yifei didn't speak, closed his eyes, and focused all his energy on activating the small vortex in his dantian.

The fluctuations, drawn by the small eddies, became increasingly clear—the fluctuations of a heartbeat!

Shen Yifei opened his eyes and looked at Ao Ting, "Your eldest sister might still be alive!"

"What?" Ao Ting's eyes widened. "Second brother-in-law, what did you say?"

"I'm saying, your eldest sister might still be alive!" Shen Yifei held the jade hairpin up in front of him. "I don't know what method your eldest sister used, but this jade hairpin can feel her heartbeat!"

Ao Ting's lips trembled twice, and his eyes instantly reddened.

"Second brother-in-law, you...you're not lying to me?"

"Why would I need to lie to you?" Shen Yifei put the jade hairpin back into the box, then put the box into his storage ring.

"Lend me this hairpin for a bit, maybe I'll have a chance to find your eldest sister...our eldest sister!"

"Really?" Ao Ting grabbed Shen Yifei's arm. "Second brother-in-law, if you can find my eldest sister, I'll give you half of the Dragon Palace!"

"Stop! Third brother, from now on, you're in charge of the Dragon Palace. Don't keep changing your mind about dividing it in half today and half tomorrow. If you divide it all away, how can you be the Dragon King?"

Ao Ting thought about it and realized he was right. He smiled sheepishly and said, "My third brother-in-law is right. The Dragon Palace is our home. I won't say things like that again."

Shen Yifei remembered the matter of the dragon scales, "Third brother, I really do have something I need your help with."

"What is it, brother-in-law? Just say the word! Whatever my Dragon Palace has, you can have it!"

"Actually, it's not a big deal. I need a dragon scale, preferably from a female dragon's tail, the higher the cultivation level, the better."

"Dragon scales?" Ao Ting was taken aback. "What do you need those for?"

"I need a friend of mine who has been poisoned and needs dragon scales as a medicinal ingredient."

"You and my second sister last night...didn't you ask her for it?" Ao Ting looked at Shen Yifei with a lewd grin. "You two did *that*, it's just a matter of giving her a mouth, how could she not give it to you?"

"Ugh, don't even mention it. The original plan was to have sex with her, but now she's my wife. The thing on my woman's butt has been used to drug someone else. Just thinking about it makes me uncomfortable."

Ao Ting thought for a moment and nodded. "That makes sense. We should keep our own women and not let outsiders take advantage of them. I'll find a way to get one right now."

Then, he gave Shen Yifei a mysterious smile and said, "Come with me."

Ao Ting led Shen Yifei out of the treasure vault, and after many twists and turns, they arrived at a house in front of the back hall of the Dragon Palace.

"Second brother-in-law, wait here for me for a moment, I'll be right back." After saying that, he pushed open the door and slipped inside.

Shen Yifei waited outside the door for about the time it takes to drink a cup of tea. When the door opened again, Ao Ting came out holding a jade box.

"Here you are, brother-in-law. These are the seven golden scales that Mother shed back then. I got one for you." Ao Ting stuffed the jade box into Shen Yifei's hand.

Shen Yifei opened the jade box and saw a golden dragon scale inside. The scale had clear patterns and emitted a faint luster, clearly indicating that it was no ordinary item.

Shen Yifei gently stroked it twice, thinking to himself, "This thing grows on the Dragon Queen's buttocks," and even compared it with Ao Ying's.

The dragon scales of the Dragon Queen Jingci were darker in color, while those of Ao Ying were lighter.

"Xinghe, take a look, is this dragon scale enough?" Shen Yifei asked in his mind.

"That's enough! Brother, this dragon scale is of excellent quality; it's enough to remove the restriction on that old blood."

Shen Yifei closed the jade box, put it into his storage ring, and patted Ao Ting on the shoulder. "Third brother, thank you for your thoughtfulness."

The two exchanged a smile, everything understood without a word.

After the two left the treasure vault, Shen Yifei was about to return to Wanghai Pavilion to rest when Ao Ting stopped him.

"Second brother-in-law, don't rush off. I'll take you somewhere that will broaden your horizons tonight."

"Where?"

Ao Ting said in a low voice, "My third uncle owns a brothel, and they're having a 'Queen of Flowers' competition tonight. I heard there are quite a few good ones. Since you're free anyway, why don't you come with me?"

Upon hearing this, Shen Yifei's heart stirred.

Ao Chong's brothel.

Isn't this a perfect opportunity to scout out the enemy's situation?

This is a good opportunity to find out more about the Third Prince beforehand; we might even discover something.

"Okay, I'll go take a look." Shen Yifei nodded. "But this has to be kept a secret. Don't let your second sister know."

"Don't worry, I guarantee no one will know."

Shen Yifei could tell from the kid's appearance that he frequented those kinds of places.

Who would have thought that this young man, who gets excited at the mere mention of brothels, would become the Dragon King's successor tomorrow?

Soon, it was evening.

Shen Yifei followed Ao Ting and slipped out through the back door of the Dragon Palace.

The two changed into ordinary clothes and followed the winding underwater street until they arrived at a brightly lit pavilion.

The building is three stories high and constructed of pink coral. Two rows of large pink lanterns hang at the entrance, each with the words "Zui Long Xuan" written on it.

Two rows of scantily clad sea tribe women stood at the entrance, each with a graceful figure, and they would swarm around any guest they saw.

"Oh my, isn't this the Third Prince! It's been so long!" A heavily made-up middle-aged woman swayed her hips as she approached, her eyes shining as if she had seen a god of wealth.

Ao Ting gestured for silence. "This Crown Prince has brought a distinguished guest; he must be given the best seat!"

The woman quickly lowered her voice, "Third Prince, the best private room has been reserved for you!"

Then he looked Shen Yifei up and down and discovered that he was actually a human.

Seeing his extraordinary demeanor and handsome appearance, she smiled broadly and said, "Young master, you have a fine appearance. Is this your first time visiting our Zuilongxuan?"

Shen Yifei cupped his hands in greeting, said nothing, and followed Ao Ting inside.

The first floor of Zuilongxuan is a hall with a circular platform in the center covered with a large red velvet carpet, and tables for drinks are placed around it.

There were already quite a few people seated, including dragons, sea creatures, and two human merchants, each with a girl by their side, drinking and chatting, creating a lively atmosphere.

The second floor consists of private rooms arranged in a semi-circle around a raised platform. The curtains are partially drawn, allowing a view of the entire first floor from inside, but those downstairs cannot see what is happening upstairs.

Ao Ting, familiar with the place, led Shen Yifei to a private room in the middle of the second floor, lifted the curtain, and went inside.

"Second brother-in-law, sit down." Ao Ting plopped down and poured two glasses of wine. "This Drunken Dragon Pavilion is the most profitable business under my third uncle's management. The courtesan competition is held every month, and they make a fortune every time."

Shen Yifei picked up his wine glass and took a sip. The wine was good; although it wasn't as mellow as the "Immortal's Intoxication," it was still considered high-quality.

Ao Ting continued, "Whoever wins the title of courtesan tonight can enjoy the night here, or they can buy her away."

"Can I still buy it?"

"Yes, many of these women were bought from overseas, and some were even kidnapped. I heard that tonight's courtesan comes from the Northern Sea, and is said to be a virgin. Uncle has put in a lot of effort for tonight."
