Tu Shan Duoduo left the house, while Zhang Fan remained hidden inside.

Not long after, Tu Shan Duoduo returned, her face covered in a thin layer of sweat, her voice trembling slightly: "You must not let the demon know that I was the one who revealed it, otherwise my family will die a terrible death."

"Also, nobody knows where the key to the treasure vault is, but he used to really like Miss Qin Qing. She's now the most beautiful courtesan at Qingfeng Pavilion. You could try looking for clues there."

"Thank you." Zhang Fan took the map and left.

The treasure pavilion of Tushan Guanfu is located in Qingfeng Tower.

Although the name sounds elegant, this place is an out-and-out brothel.

The previous demon king loved human life, so the demon city was exactly the same as the human world.

Qingfeng Tower used to be a place for listening to storytelling and music, but it was later turned into a brothel by the current Demon King Tushan Guanjing.

As soon as Zhang Fan entered the room, a vixen-like madam came over, looked him up and down, and her eyes revealed disdain: "Esteemed guest, may I ask which girl you would like to serve?"

Zhang Fan casually pointed to the woman dancing on the stage: "That's her."

This woman is the most popular; she must be the most popular courtesan.

Fortunately, he admitted his mistake.

The madam smiled broadly, but the smile didn't reach her eyes: "Guest, you have excellent taste. That's Miss Qin Qing, the most human-like demon in our entire Qingfeng Pavilion. She's our top choice. Whether she'll take a liking to you or not depends entirely on luck."

Zhang Fan didn't understand, so the madam explained, "Later, Miss Qin Qing will give you a question. If you can satisfy her, she will be willing to accompany you even if you don't give her a single demon coin. If she is not satisfied, even if you give her a mountain of gold, she will still not be satisfied."

After Qin Qing danced, she sang a song, a nocturne by Jay Chou from a few years ago.

The other demons listened with rapt attention, clapping and cheering.

The cheers from the audience did not satisfy Qin Qing; instead, they made her slightly irritated.

This mob has no sense of appreciation whatsoever.

Why applaud Jay Chou if his songs aren't even good?

Suddenly, she noticed Zhang Fan standing in the corner. He stood tall with his arms crossed, listening quietly to the song.

This is the kindred spirit she's been searching for.

Qin Qing's face lit up with joy: "Little demon, can you sing 'Rooftop'?"

Zhang Fan was lost in thought when he suddenly realized that all the demons were looking at him, including Qin Qing.

A little demon next to her said with a mix of jealousy and envy, "I really envy you being able to sing 'Rooftop' with the courtesan."

Zhang Fan: "?"

Someone immediately handed over a microphone.

Hearing the familiar melody, Zhang Fan hummed along for a few lines and sang a duet with Qin Qing.

When the music ended, the entire venue was silent for more than ten seconds before thunderous applause erupted.

Zhang Fan's gaze remained fixed on Qin Qing, and to onlookers, it appeared that he was completely captivated by her.

He noticed that Qin Qing had a pimple scar on her arm.

"Brother, you're amazing! You sang it without missing a single word."

"And you can switch between your true and falsetto voice, you're practically no different from a human."

Zhang Fan's inner thoughts: I am just a human being, thank you.

Qin Qing gave Zhang Fan a satisfied look: "Young man, I'm looking forward to spending the night with you. Come with me."

The other demons protested: "Qin Qing, you always made us do problems before, why did it change when it came to him?"

"It's unfair, extremely unfair!"

"What if someone else did it right?"

As things escalated, Qin Qing said coldly, "If I'm willing, then don't come again if you're not happy."

At this moment, a big spender started clamoring for a refund. The madam had no choice but to coax Qin Qing, saying, "My dear daughter, please don't cause your mother any more trouble. I beg you."

Qin Qing remained unmoved. After the madam left, he could only plead with Zhang Fan: "Sir, please let Qin Qing set the question. If you lose, I'll give you ten thousand yuan."

Zhang Fan said nonchalantly, "I could have been Qin Qing's honored guest anyway, why bother?"

The madam gritted her teeth and said, "Ten thousand yuan, you could buy a house with that."

What if I win?

Madam: "If you win, this money is yours too."

Zhang Fan shook his head again: "I still think Miss Qin Qing is the best."

The madam raised the price to 100,000 yuan, and you could tell from her expression that her heart was bleeding. Zhang Fan finally agreed.

"Miss Qin Qing, how about we follow the proper procedures?"

Qin Qing's cheeks were flushed. She really liked the way Zhang Fan bargained, unlike these stupid monsters who seemed to have no brains.

Actually, she was also secretly hoping that Zhang Fan could answer those questions.

Qin Qing gave Zhang Fan a few questions, and when Zhang Fan looked at them, he realized they were just middle school math problems; he could give the answers without even having to write out the steps.

The other monsters racked their brains, their brows furrowed, deep in thought, while Zhang Fan gave the answer without the slightest hesitation.

Qin Qing's eyes lit up: "How did you figure out the answer so quickly?"

Zhang Fan asked, puzzled: "Isn't it just a matter of having a brain?"

Other demons: ...

They have brains, they just don't use them very well.

Qin Qing said shyly, "Please follow me, sir."

Zhang Fan: "Wait a minute."

Everyone was looking at Zhang Fan, wanting to hear what he had to say.

Zhang Fan: "Check, please."

The madam's heart was bleeding. She handed Zhang Fan a piece of paper with writing on it that Zhang Fan couldn't understand.

In front of so many people, Zhang Fan didn't believe the madam would lie. He stuffed the paper into his pocket and followed Qin Qing.

The antique-style room filled with fragrance is Qin Qing's bedroom.

Qin Qing handed over a glass of wine: "May I ask how this guest is addressed?"
