Chapter 394

After strolling around the school for half a circle, Song Yao went to the restroom, while Xu Qingzhou was bored and looked at the bulletin board at the school gate.

The first few pieces were actually the display positions for outstanding alumni.

The first was Xu Qingzhou, introducing various award-winning situations.

The second was Song Yao, still using that photo from freshman year that was widely circulated, studying under economist Li Daiyue, winning scholarships and such.

At that time, School Beauty Song was still very cold.

Xu Qingzhou shook his head and sighed, scanning past them, and couldn't help but be stunned at one of them.

An old acquaintance, Zhang Yuxin.

After Xu Qingzhou finished reading the introduction, he roughly understood.

Zhang Yuxin was the same as before, entering the entertainment industry. Last year, the costume TV series she starred in was a small hit, and now she was also a small-time famous actor.

It seemed she was much smoother than before.

Xu Qingzhou didn't care about Zhang Yuxin's experience and what was different from before. Just as he was about to lift his foot, a cold voice rang out.

"It's been three years, and you still can't let go?"

Xu Qingzhou turned his head and saw Song Yao staring at him coldly.

He was stunned.

This...

It shouldn't be. This girl would actually be jealous?

Seeing Xu Qingzhou a bit frightened, Song Yao raised her eyebrows, the corners of her mouth lifting. "Do we look like a young couple in the honeymoon phase?"

Xu Qingzhou rolled his eyes, secretly thinking he almost fell for it. He knew Song Yao wasn't someone who was easily jealous. With her personality, if she really wanted to be jealous, it should be a slap coming his way.

"Let's go."

Song Yao turned back to glance at the bulletin board and asked: "Teacher Xu, seeing the person you liked before, you don't have any fluctuations in your heart?"

Xu Qingzhou answered decisively: "None."

"I don't believe it. You dare to say you don't have a bit." Song Yao hugged Xu Qingzhou's arm and asked in a low voice.

"Song Yao, the theory of punishing hearts is invalid here."

Xu Qingzhou didn't fall for it. He paused and turned to ask back: "However, aren't you worried that I really have ideas?"

Song Yao shook her head. "I believe you..."

Xu Qingzhou hadn't had time to be moved when School Beauty Song said softly: "I believe you are someone who cherishes your life."

"."

For the next few days, Xu Qingzhou didn't continue to struggle with whether the Reich metric could solve the Riemann Hypothesis, but continued to look at the previous data, looking for ideas.

He was about to go abroad, so he wasn't in a hurry, cooking a few meals for old Xu and them at home, accompanying the old couple more.

However, next month was Song Yao's birthday, and Xu Qingzhou also started thinking about what gift to give her. The sense of ritual between young couples was always indispensable.

In addition, through Senior Sister Zhang Xiaohe, who was Li Daiyue's student, the two selected two houses, which needed to be seen on-site.

July 13th, Guo Ziyang and Ding Jiahui also returned from Kyoto, and the four gathered for a hot pot meal.

July 15th, 9:50 AM.

Rongcheng Shuangliu Airport.

Saying goodbye to the four middle-aged people, Xu Qingzhou and Song Yao stepped onto the plane to San Francisco, USA.

The whole journey was about 14 hours, arriving around 8:30 AM San Francisco time.

Business class, the two took a few photos first, and then each read a book.

Song Yao was reading the paper on financial investment and corporate valuation sent by Professor Lucille Morton. What she was seeing now was called something like the impact of the power gap between CEOs and chairmen on company performance volatility.

Xu Qingzhou was trying to analyze the Riemann Hypothesis using algebraic methods.

"The sum of the power series a+ax+ax+... that converges everywhere is called an entire function. From this, it can be known that every polynomial is an entire function..."

"f(z) is an entire function not identically equal to a constant. If there is a point a in the plane such that f(a)=0, then a is called a zero of f(z). In other words, a zero is a root of f(a)=0." Xu Qingzhou pondered, while writing down rows of formulas on it.

His current idea was to first parse the Riemann Hypothesis in various ways, and then find a proof method.

Time passed slowly.

The clouds under the plane had disappeared, the sky was clear, and it was still a vast blue.

Song Yao read for an hour, then yawned and slept leaning on Xu Qingzhou's shoulder.

Sleepiness might really be contagious. Song Yao's breathing gradually became steady. Xu Qingzhou's sleepiness gradually came up, so he simply threw away the paper and planned to sleep for a while.

Xu Qingzhou woke up earlier than School Beauty Song.

Seeing Xu Qingzhou staring straight at her, Song Yao stretched and said, "Is it very beautiful? Stared dumbfounded."

"You're drooling," Xu Qingzhou said.

Song Yao narrowed her eyes at Xu Qingzhou, rubbed her mouth against his clothes, and plunged into his arms. Anyway, Xu Qingzhou had seen her sloppy appearance, and now she didn't care about any image problems at all.

Xu Qingzhou smiled, sighing that School Beauty Song was becoming cuter and cuter.

Especially this contrast.

Long-distance flight was the most boring, nothing more than sleeping, reading, and eating, but fortunately, there were two people who could talk. At 8:00 local time, the plane landed at San Francisco International Airport on time.

After reporting safety to both parents, the two pushed their suitcases to the booked hotel to rest. It would take another 6+ hours of flight from San Francisco to Boston, so they planned to rest for a night, just right to adjust the jet lag.

The two stayed in a four-star hotel, a twin room.

After more than ten hours of rushing, even the light in Song Yao's eyes was gone. When truly tired, one actually only wanted to lie down, and there was really no desire to stroll around the scenic spots.

The two lay on the bed, Xu Qingzhou glancing at School Beauty Song beside him.

Mountains from the side, peaks from the side.

He secretly let out a breath, did a fish jump up from the bed, and pulled the curtains shut with a "pa."

"What are you doing?"

"Checking the living environment."

Xu Qingzhou planned to check every corner of the hotel first. Whether domestic or foreign, it was inevitable that some perverts would appear, and hidden cameras were common.

Being cautious was never wrong.

Song Yao pursed her lips, lying sideways on the bed, one hand supporting her head, and asked Xu Qingzhou: "Are you hungry?"

"Are you hungry? Then we'll go eat later."

Xu Qingzhou was rummaging through the bedside socket. They had eaten a light meal on the plane two hours ago.

Song Yao nodded and didn't speak.

Xu Qingzhou finished checking the bathroom and came out, saying: "Hmm, nothing..."

He froze, looking at School Beauty Song who was tying her hair. A bad premonition suddenly surged in his heart. This scene was really a bit familiar. "You wouldn't be wanting to..."

Pfft~

Before Xu Qingzhou finished speaking, he was pounced on the bed by Song Yao.

"."

Song Yao's gaze was fiery, even licking her lips, looking exactly like a female hooligan. "Compared to eating, I want to eat you more right now."

Xu Qingzhou's mouth twitched. He really wanted to say: "This was clearly my line."

"Be gentle... woo~"

He gave up struggling. Although this posture was a bit humiliating, it had to be said, it counted as an entertainment match.

It was just that this girl was bad and loved to play.
