With regards to such a request, Duan Lingfei obviously could not reject it.

Just as he finished speaking, Bai Youqing had already turned around and brought out a pen and paper from the secretary behind him. He drew a pattern on the paper and handed it over to Duan Lingfei.

"In the eighteenth century, there was a beautiful little town in Europe, the castle of Gonisburg, where a small river snaked through a park and seven bridges connected the two islands and the islands in the river to the river's banks. I would like to ask if it is possible to start from any of these four continents, just once across each bridge, and then return to the beginning."

And on that piece of paper, was the rough outline of the two Isle s and the seven bridges that she mentioned earlier.

"What is this?" Duan Lingfei was shocked, who would ask such a thing on their first meeting?

But Liu Yanxia, as if he was accustomed to it, went close to him and whispered in his ear: "Bai Youqing is like this. Only by making her question, can I have the qualification to be friends with her."

"So you did the same thing to her?"

"What she gave me was relatively simple, but I wish I hadn't done it myself." Liu Yanxia's expression was a little pained.

"Hey, what are you guys talking about?" Bai Youqing suddenly asked.

"No, no, nothing." Liu Yanxia immediately retreated to the side and threw Duan Lingfei a helpless and helpless look, but then said to Bai Youqing: "Duan Lingfei is the smartest one among my friends, I bet that your question will not trouble him."

"Is that so?" Bai Youqing glanced at Duan Lingfei: "Why don't I feel like him?"

This sentence was filled with contempt and immediately provoked Duan Lingfei. Was his IQ really that great?

Initially, he had no interest in doing the questions, but at this moment, he focused his attention and began to carefully observe the diagrams on the paper.

In this entire period of time, Bai Youqing had always been a calm and collected person, but Liu Yanxia was actually very perturbed in his heart.

Before this, Duan Lingfei did not know that there was a theorem called Euler's Theorem in the world, nor did he know that this problem was the problem of the Seven Bridges of Guinness, which held an extremely important place in the history of mathematics.

However, when he carefully thought about this question, it was as if a living map had appeared in his mind. There was a little person repeatedly moving between the two islands and the seven bridges. Every time he denied a route, his mind would become clearer.

After about five minutes, Duan Lingfei raised his head, looked at Bai Youqing and said: "This matter is impossible, you are messing with me."

"Lingfei, why do you say that? Think about it, think about it. " Liu Yanxia winked at Duan Lingfei and said.

"There's no need to think any further. This is something that can't be done." Duan Lingfei said with certainty.

Liu Yanxia was immediately discouraged, but what he did not realize, was that Bai Youqing's eyes suddenly lit up, and asked: "Have you heard of this question before?"

"Nope."

"Then you specialize in math?"

"Not really."

"Then you can figure it out in five minutes."

"Yes, is there a problem?"

"Haha …" Bai Youqing let out a meaningful laugh: "Nothing, congratulations, you got it right."

However, what she was thinking was — "There are only two possibilities. Either you are an unparalleled genius, or you are just a swindler who seeks fame."

As a genius with a high IQ, Bai Youqing had absolute confidence in herself. When she first met this question, she thought about it for a few days but could not find an answer.

The reason why she gave such a difficult question was because she did not want Duan Lingfei to stay by her side, so she wanted to find an excuse to send him away, but she did not expect Duan Lingfei to actually give her the correct answer after five minutes.

In Bai Youqing's heart, it was obvious that he did not believe Duan Lingfei's words. Even the famous mathematician Eola had to think hard about this problem.

Thus, a thought appeared in her mind for some reason. She must find an opportunity to expose this hypocritical swindler.

"Great." Liu Yanxia immediately cried out in joy, and then, he remembered that he was now a "sickly body", and immediately pretended to be weak: "Since that's the case, let Lingfei take my place to accompany you on a stroll in the Jianghai City, what do you think?"

"Sure." Bai Youqing nodded in agreement.

"Then I'll arrange for you to rest at the hotel for a while, and then …"

Before Liu Yanxia could finish his words, he was interrupted by Bai Youqing: "You can arrange for other people to go to the hotel. I'm not tired, I want to go for a walk."

"So it's like that. Of course there's no problem. Take my car."

"..."

Under Liu Yanxia's arrangements, Bai Youqing brought a female secretary and got on the longer version of the Cadillac with Duan Lingfei. Liu Yanxia arranged for his driver, Xiao Wang, to drive for them while he arranged for Bai Youqing's other attendants to go to the hotel.

Once they were in the carriage, Duan Lingfei took the initiative to introduce them to Bai Youqing: "Jianghai is a beautiful modern city, and also used to be the capital of the seven dynasties, it has a rich natural and human landscape, where does Miss Bai want to go?"

Bai Youqing thoughtfully looked out of the window, as if he did not hear Duan Lingfei's words. After a moment, he said indifferently: "Since you are Liu Yanxia's friend, then you are not an outsider. Can we call you by your name?"

"Of course." Duan Lingfei laughed and continued to speak. "The more famous places in Jianghai City are White Screw Temple, Golden Bell Forest, Wild Goose Falling River, Lotus Fragrance Garden, and so on.

However, before she could finish speaking, she was interrupted again. This time, the person who spoke was the secretary behind Bai Youqing: "Mr Duan, this is not the first time our young miss has come to Jianghai. The places you mentioned have long been visited by her."

The secretary's name was Monica, and she was an American woman in her thirties. She wore a business suit and black-framed glasses, and she looked very capable.

"Alright, then I wonder if the Gui Yuan Temple, Wang Jiang Tai, Xiangxi Pool, or the Heavenly Bull Lake …"

"No need." Duan Lingfei's words were interrupted by her again. She yawned and said: "Duan Lingfei, it's so boring. Can you come up with some creative ideas?"

"Creative? "Such as …"

"For example, to stimulate someone … Is there a casino in Jianghai City? "

"Casino?" Duan Lingfei was shocked.

"That's right. In the United States, we have strict control of the house. Besides, I'm not old enough to enter casinos, so I can only play online games of virtual gambling. It's too boring." Bai Youqing curled his lips and said: "Coming to the Jianghai this time, it's rare that no one is watching me, so I might as well go experience it."

"But gambling is illegal in the mainland …"

I know, but you're a local, and a friend of Liu Yanxia's. There's always a way." "Bai Youqing said in a matter-of-factly tone," "If you can't even satisfy such a small request, I don't think you need to stay by my side anymore.

"Fine." Seeing Bai Youqing's determined look, Duan Lingfei clenched his teeth and whispered a few words to the driver in front.
