On Dragon Girl's Math Skills

A chilling voice rang out, and the surrounding sweltering temperature plummeted in an instant. Ma Feifei's bloodshot brain cleared instantly, and he grabbed Cang Lan's hand and pushed her away.

"Ah!" Cang Lan responded and stumbled backward, falling to the ground. She looked at Ma Feifei with a pitiful expression, as if she might burst into tears at any moment.

Ma Feifei wasn't in the mood to look at her right now; instead, she turned to look at the figure at a long table next to Li Shu.

Yun Qingyang stood expressionless in front of the long table, on which lay a sheet of drawing paper. She held a calligraphy brush in her hand, but the brush had completely frozen solid and was clearly unusable.

"Ahem." For some reason, Ma Feifei felt a little awkward. He coughed lightly, straightened his clothes, and said seriously, "Let's talk about worldly affairs..."

Cang Lan glanced at Yun Qingyang with a slight smile, then slowly got up and sat back down on the small stool. There were some stains on her skirt, but Cang Lan didn't mind at all, and didn't even bother to remove them. She looked up at Ma Feifei and said with a playful smile, "Shopkeeper, you've kept this a secret for a long time. I didn't even know you had a wife."

"Grand Dean, don't talk nonsense. She's an employee of our Bookstore. You can't slander her," Ma Feifei said seriously. He now finally understood why cultivators on the mainland turned pale at the mention of Cang Lan. This woman was a Fairy type! And the kind that would devour people without spitting out the bones. Ma Feifei felt like he had almost fallen for her tricks.

"Hehe," Cang Lan chuckled dismissively, then suddenly leaned forward, getting close to Ma Feifei, and whispered, "Would the shopkeeper mind having another lady?"

"..." Ma Feifei was speechless.

"Giggle giggle"

Cang Lan laughed so hard her body trembled, but the temperature in the backyard was getting lower and lower...

"Alright, alright, I won't tease the shop owner anymore. Today is the anniversary celebration of Mysterious Bookstore, so I won't bother you any longer. I'll come to visit again early tomorrow morning. I hope the shop owner won't turn me away!" Cang Lan drew out a long, trembling voice, which made people's hearts flutter.

"Of course not." Ma Feifei felt a chill run down his spine. If he didn't get rid of this big shot soon, the entire backyard might be turned upside down. He quickly got up to see him off.

"Tsk tsk," Cang Lan said, seeing Ma Feifei's expression. She took two steps to stand in front of Ma Feifei, glanced at Yun Qingyang behind him over his shoulder, and teased, "Shopkeeper, this isn't good."

"What's wrong with it?" Ma Feifei was a little confused.

Cang Lan didn't answer. She opened her palm, and a black leather whip appeared in her hand. The whip was made of some unknown material and had tiny, densely packed granules on it.

"Here, this whip is a gift for the shop owner." Cang Lan presented the black leather whip with both hands.

Ma Feifei took it instinctively, but he still didn't understand why.

At this moment, Cang Lan leaned forward slightly, close to Ma Feifei's ear, looked at Yun Qingyang with her peach blossom eyes, blinked gently, and parted her red lips. "This is a good thing to restore the husband's authority!"

Ma Feifei watched Cang Lan's departing figure, then looked at the leather whip in his hand, completely bewildered.

"Damn it, this old woman actually has some unusual fetishes!"

"No, no, no!" Ma Feifei shook his head violently, threw the whip into the corner, and then shook his body. "This old woman is too scary, too scary."

Although Cang Lan had always acted unrestrained and carefree, Ma Feifei noticed that Cang Lan had been in an active state since entering the room, controlling the entire conversation and even leading Ma Feifei astray.

Moreover, although it seemed like Cang Lan was the one flirting with him, Ma Feifei didn't actually gain anything and even made Yun Qingyang resentful. Could this be considered a fire breaking out in the harem?

Thinking of this, Ma Feifei glanced at Yun Qingyang and found that she had recovered and was painting with her head down, except... she was holding the brush upside down...

Ma Feifei walked over and asked in a low voice, "Qingyang, were you angry just now?"

"No," Yun Qingyang replied in a muffled voice.

"Really not?" Ma Feifei raised her voice slightly.

"No!" Yun Qingyang also raised her voice.

"Then why didn't you notice you were holding the brush upside down?" Ma Feifei said, pointing at Yun Qingyang's calligraphy brush.

"I did it on purpose, it's none of your business." Yun Qingyang glared fiercely at Ma Feifei, then picked up a pen and started drawing, leaving Ma Feifei completely bewildered.

"Hey Qingyang." Ma Feifei nudged Yun Qingyang's arm and called out softly.

"What?" Yun Qingyang asked impatiently.

"Are you jealous?" Ma Feifei asked with a hint of smugness.

"I only eat Spirit Crystal and Plum Blossom, I'm not jealous." Although Yun Qingyang's tone was still impatient, the surrounding temperature slowly rose, indicating that her anger was beginning to subside.

"Sigh, you're really stupid!" Ma Feifei shook his head and sighed helplessly after hearing Yun Qingyang's answer. If Yun Qingyang had even half the emotional intelligence of Cang Lan just now, she wouldn't have answered the question like that. As a result, Ma Feifei's hard-won sense of pride instantly vanished.

"I'm not stupid at all. Zhang Caicai asked me to borrow Spirit Crystal the other day and tried to trick me, but I saw Foresight her. How could I be stupid?" Yun Qingyang said indignantly.

"Oh? Zhang Caicai tricked you out of your Spirit Crystal? How did she do it?" Upon hearing this, Ma Feifei became serious. Such deceptive behavior was absolutely unacceptable in the Mysterious Bookstore. If Zhang Caicai was really as Yun Qingyang said, then Ma Feifei would have to consider firing this young cook.

"He said he wanted to buy a set of kitchen utensils, but he was short 10,000 Spirit Crystal, so he asked to borrow them from me, saying he would return 11,000 Spirit Crystal to me the next day," Yun Qingyang said.

"So you borrowed it?" Ma Feifei asked.

Yun Qingyang nodded, then shook his head, and said, "I didn't have the ring on me at the time; it was in my room. So I asked Luan Feng for 10,000 Spirit Crystal to give to him."

"And then what?" Ma Feifei continued to ask.

"Smack!"

Yun Qingyang suddenly slammed his brush on the table and said angrily, "The next day, Zhang Caicai told me that she hadn't saved up 11,000 Spirit Crystal yet and said she would give them to me on the third day. But I also told Luan Feng that I would return them to her the next day. Since Zhang Caicai wouldn't give them to me, I had to take out 10,000 Spirit Crystal myself to return them to Luan Feng. So tell me, doesn't Zhang Caicai now owe me 21,000 Spirit Crystal?"

"Uh..." Ma Feifei was a little confused and hadn't reacted yet.

Yun Qingyang got more and more excited as she spoke, saying, "But you know what! When he came back to return the money on the third day, he only gave me 11,000 Spirit Crystal. Don't you think he's treating me like a fool?"

"Uh... wait a minute." Ma Feifei was a little confused, feeling that something was wrong, but he couldn't figure out what it was for the time being, so he could only start from the beginning.

"What am I waiting for! He's just treating me like a fool. If he ever asks me for money again, I definitely won't lend it to him." Yun Qingyang looked unhappy as she mentioned this, and stopped drawing altogether, casually putting the painting away.

"So what did you do in the end...?" Ma Feifei suddenly asked.

"Of course, I made him return the remaining eleven thousand to me! But he didn't have enough Spirit Crystal, so I gave him a few days to collect Spirit Crystal before returning them to me." Yun Qingyang said, then turned to look at Ma Feifei, asking with a smug look, "Ma Feifei, don't you think he's incredibly clever!"

"..." Ma Feifei looked at Yun Qingyang, who had a smug look on his face, and nodded blankly.
