Chapter 534: Chapter 533: Rainy Day, Sleeping Day

"Wake up, wake up. Don’t sleep anymore, it’s time to get up and go home..."

Jolted awake by Wang Chuan, Yan Feifan groggily sat up on the sofa. He noticed the room was a bit dark, and he could hear the pitter-patter of rain and the whistling of the wind outside.

Today was Friday!

On Wednesday morning, Yan Feifan, working alongside Lo Jun and Zheng Ling, had successively completed two intraspinal tumor surgeries.

In the afternoon, he discussed a patient’s surgical plan with Dr. Kevin Vega, who had rushed over from the United States.

The patient Mr. Vega brought this time had a tumor in the cervical spine.

Mr. Vega was also capable of performing this surgery.

However, after watching a video of an intraspinal tumor resection surgery previously performed by the man, Yan Feifan, to ensure the best possible outcome, directly proposed that he perform the entire operation himself.

After careful consideration, Mr. Vega agreed.

However, he also stated that he could take over for Yan Feifan at any point during the surgery.

As for the patient Qin Feng had brought this time, it was a thoracic vertebra tumor.

Mr. Qin didn’t volunteer to be the lead surgeon. Instead, he brought a neurosurgery expert from the PLA General Hospital.

On Thursday, Yan Feifan first spent an hour completing the puncture and injection procedure for the domestic patient’s thoracic spine tumor.

Afterward, he spent nearly seven hours as the lead surgeon, completing the cervical spine tumor resection for the patient from the United States.

After this surgery was completed, Mr. Vega gave Yan Feifan two thumbs up.

Time slipped by to Friday. Binhai was hit by the tail end of a typhoon sweeping past the coast, and it had started raining early in the morning.

Whether it was due to the sound of the wind and rain or because he was simply exhausted from the week, Yan Feifan had actually dozed off while discussing next week’s surgical observation meeting with Director Wang Chuan and listening to him share his surgical experience...

Drifting off to the sound of the rain and wind, Yan Feifan slept straight through until nearly six in the evening.

Yan Feifan got off the sofa, stretched out his arms with a big yawn, and couldn’t help but let out a comfortable groan, feeling a sense of total relaxation coursing through his body.

Even though he had slept on the office sofa, which couldn’t compare to the comfort of his own bedroom, the quality of his sleep this time was genuinely excellent.

Yan Feifan believed part of the reason was today’s rainy weather.

He had been looking into a "rain sound lullaby" recently, and after consulting some materials, he discovered there were quite a few scientific reasons why rainy days make people drowsy and improve sleep quality.

First, an increase in melatonin secretion.

Melatonin plays a role in regulating the body’s biological clock.

During rainy and cloudy weather, the sun is blocked by dark clouds, causing the body’s melatonin secretion to be significantly higher than on sunny days. This, in turn, makes us feel more tired.

Second, a decrease in serotonin.

Sunlight exposure increases the body’s level of the euphoric neurotransmitter 5-hydroxytryptamine (serotonin).

On overcast and rainy days, the body produces less serotonin. A lower level of serotonin can easily lead to melancholy and a feeling of lethargy.

Third, an increase in humidity.

On rainy days, the air humidity is higher, and the concentration of negative ions in the air also increases noticeably.

An increase in negative ions can improve the function of the nervous, cardiovascular, circulatory, and respiratory systems, making people feel more comfortable.

Negative ions also have a sedative and hypnotic effect, making one feel very sleepy.

Fourth, the sound of raindrops.

The sound frequency of rain is typically between 0 and 20 kilohertz.

This type of sound frequency is known as "white noise."

This "noise" doesn’t irritate us; on the contrary, it causes the brain to produce alpha waves, which unconsciously relax the brain, bringing it closer to the state it’s in during sleep.

Therefore, the sound of rain can be considered a natural lullaby.

Catching sight of Director Wang Chuan’s displeased expression out of the corner of his eye, Yan Feifan quickly reigned in his unabashed stretching.

"That emergency surgery on Monday night seriously disrupted my work and rest schedule. It wasn’t until this nap today that I’ve finally recovered."

Yan Feifan explained, then added a compliment, "It’s only here with you, Director, that I dare to relax so completely and not feel constrained."

Wang Chuan let out a soft snort. "Is that so?"

"Or is it that you think your wings have grown strong enough to ignore me?"

"How could that be!"

Yan Feifan quickly clarified his feelings, "Even though I always call you Director, in my heart, I’ve always regarded you as a great teacher, a true friend, and a respected elder."

Wang Chuan shook his head and chuckled. "You, you... Who did you learn this from? You’ve become quite the smooth-talker."

After a pause, Wang Chuan’s tone became animated. "Today, I had my staff make some calls to confirm. Of those who received our invitations, thirty-one have confirmed they will attend the observation."

"Eleven said they are tentative."

"Only twelve have definitively declined, citing lack of time and other reasons."

"By then, with a few uninvited guests added to the mix, I estimate the surgical observation seminar next Friday will have about fifty people in attendance."

"That’s a pretty decent turnout."

Wang Chuan added, "Ouyang Yanran also mentioned that a medical products company under Baiyulan will provide sponsorship."

"We just need to let them hang a banner and put up a promotional sign in the observation room and at the seminar venue."

Yan Feifan let out a soft "oh" and asked, "Director, did Yanran mention if there’s been any progress in her collaboration with Baining Medical Technology?"

Wang Chuan shook his head. "I didn’t ask about that, and she didn’t bring it up."

"This surgical robot project must have had hundreds of millions in initial R&D investment."

"A collaboration on a project this big isn’t easy to finalize. Even if both parties are willing, it’s normal for back-and-forth negotiations to drag on for half a year or even a full year."

After a pause, Wang Chuan switched topics with a smile. "Your sister, Ziruo, called this afternoon. She said she’s accepted the villa."

"Your sister also said that the Lin Family was quite decent about it this time. They only took antiques, calligraphy and paintings, art pieces, handicrafts, expensive flowers and plants, and their bedding!"

"The furniture, appliances, kitchen supplies, and so on were all left intact."

"You guys just need to buy some bedding, and you can move in."

Wang Chuan chuckled happily. "From now on, you’ll be living in Zone B, and we live in Zone C. It’ll be much more convenient to visit each other."

Yan Feifan corrected him, "We’ll probably only stay there on weekends or holidays. It’s a bit too far for commuting to and from work."

"Perhaps my sister will live there long-term."

"She loves to show off. Now that she’s living in a villa, she’ll probably shout it from the rooftops until everyone knows."

Wang Chuan laughed heartily. "I’ve already received an invitation from your sister for the housewarming party tomorrow afternoon..."

When Yan Feifan and Yu Suye returned to their place at Zuimo Court, they found that not only was his sister not there, but Du Qiu hadn’t prepared dinner either.

Yan Feifan called his sister and found out they were at a mall, picking out bedding.

"Feifan, you and Su Ye should enjoy some time to yourselves. Go out and find a place to eat."

"We’ll probably be back late tonight."

Just then, Zeng Ni’s voice unexpectedly cut in on the call.

"Feifan, the melody decomposition, frequency decomposition, and the frequency-melody combinations for the rain sound are all done."

"I’ll give you the files when Ruoruo and I get back..."

After ending the call with his sister and Zeng Ni, Yan Feifan looked at Yu Suye and asked, "So, about dinner?"

Yu Suye glanced at the rainy weather outside the window and said, "Rainy days are for sleeping. Why don’t we just cook something simple and then go to bed?"

"Okay, to bed it is..."
