Yan Feifan accepted the gratitude of the patients who had awakened from their deep comas, along with their families. After taking some commemorative photos, he and the lab staff saw them out of the Little Red House. With this, the treatment and recovery of patients number one, three, and four at the hospital had successfully come to an end.

While recuperating at home, they still needed to regularly report their physical recovery progress to the Infrasonic Awakening Treatment Project team. If any abnormal physical conditions occurred, they were required to contact the team immediately. This reporting period was tentatively set for three months.

When Yan Feifan returned to his office in the Little Red House, he was surprised to find Fan Xiaoxiao still there, fiddling with the flowers given by the patients.

Fan Xiaoxiao said, “They were all brimming with tears. It’s clear their gratitude toward you is genuine and comes straight from the heart.

“Feifan, don’t you feel incredibly proud and fulfilled?”

Yan Feifan replied casually, “Just average.”

Fan Xiaoxiao curled her lips and teased, “Yan Feifan, just keep pretending! Act all you want!

“You were like this when we were kids. A little brat pretending to be deep and mature, putting on that aloof act like you were better than everyone else.

“It’s just so infuriating to watch!

“I can’t believe you still haven’t kicked this awful habit!”

Too lazy to entertain this annoying girl, Yan Feifan unceremoniously waved her away. “Fan Xiaoxiao, go do whatever it is you need to do. I have to start working.”

Fan Xiaoxiao puffed out her cheeks in anger, but remembering she was the one asking for a favor, she could only swallow her pride for now. Replacing her frown with a smile, she said, “Feifan, we haven’t seen each other in so many years.

“As your childhood friend, and since you’re doing so well for yourself, shouldn’t you treat me to a nice welcome dinner tonight?”

Yan Feifan scoffed softly and didn’t mince his words. “Childhood friend? More like an enemy.

“Don’t tell me you’ve forgotten how you and your brother used to bully me?”

Fan Xiaoxiao let out a dramatic gasp and whined coquettishly, “Feifan, our childhood roughhousing should have turned into beautiful memories after being washed over by all these years!

“At the very least, we should let bygones be bygones with a smile!

“How can you still be so petty and narrow-minded?”

Yan Feifan tapped his head a few times and snorted. “My memory is too good. I can’t forget those unpleasant things.

“Fan Xiaoxiao, the fact that I didn’t kick you and your brother to the curb and even agreed to operate on your nephew is magnanimous enough.”

Fan Xiaoxiao retorted, “At the end of the day, you’re still just petty and holding a grudge.”

She then continued, “Look at me, I was thrown down hard by your assistant yesterday…

“Last night when I went back and looked in the mirror, I found three large bruises on my back. I had to sleep on my stomach, and it still hurts now.

“Even after being thrown so hard, didn’t I pretend like nothing happened when we met today?”

Yan Feifan rolled his eyes. “What happened yesterday was purely your own doing.”

Despite his words, he did feel a bit guilty. Softening his tone slightly, he said, “Fan Xiaoxiao, my schedule is tight, and I have a lot of work. I really don’t have the time to treat you to a welcome dinner.

“Hey, why don’t you go find Xue?

“He used to be your little shadow back in the day. If he knows you’re back, he’ll definitely take good care of you!”

Fan Xiaoxiao looked disgusted. “I’m not going to look for him.”

Suddenly, she perked up with exaggerated excitement. “Hey, Feifan, I heard you have a girlfriend as beautiful as a goddess, known as the most beautiful woman in the hospital.

“Why don’t you introduce us?”

“Her name is Yu Suye, and she’s in trauma surgery,” Yan Feifan replied casually. “She should be in surgery right now. I’ll introduce you two when we have time.”

As he spoke, Yan Feifan accessed the Infrasonic Awakening Experiment Project database on his tablet and pulled up the medical records of the new batch of trial patients. “I really need to get to work now.

“Make yourself at home…”

Fan Xiaoxiao lingered for a little while longer, but seeing that Yan Feifan was completely engrossed in studying the patient records and ignoring her, she felt bored and left in a huff.

When lunchtime arrived, Yan Feifan went to the cafeteria for a quick bite before heading over to Inpatient Building 5.

This building mainly housed patients from the neurology and neurosurgery departments. Having gathered some prior information, Yan Feifan went straight to Ward 7 on the eleventh floor.

It was a three-bed ward. Yan Feifan noticed a slim, short-haired man in his thirties propped up in bed number three, playing with a 9×9 Rubik’s Cube. An oxygen tube was still inserted into his nostrils.

Yan Feifan knew that the man before him was Zhang Chao, thirty-three years old. He worked in administrative logistics at a public institution.

Over two months ago, Zhang Chao had been hit by a car while riding his electric bike home from work. He lost control of the bike, and his head slammed directly into a roadside lamppost. After being in a coma for two days, Zhang Chao woke up. He stayed in the hospital for another two days and was discharged after a physical examination showed no issues. However, less than three days after returning home, Zhang Chao’s memory had improved astonishingly.

At the same time, his body began to inexplicably lose weight. In the past two months, he had lost over twenty pounds.

Wearing his white coat, Yan Feifan approached bed number three and locked eyes with Zhang Chao, who looked up upon hearing the movement.

“Hello, Mr. Zhang! I’m Yan Feifan…”

“I know you…” Zhang Chao interrupted him, his voice laced with excitement. “You’re the genius doctor of the Affiliated Hospital with a photographic memory.”

As he said this, he showed the multicolored Rubik’s Cube in his hands to Yan Feifan, then moved both hands simultaneously, rapidly twisting it over a dozen times.

Zhang Chao handed the cube to Yan Feifan. “Mr. Yan, please restore the cube to how it was just now.”

Yan Feifan took the cube without the slightest pause. Without even observing or thinking, he moved both hands together, performing a series of reverse twists, and handed it right back.

Zhang Chao took the cube and examined it carefully, a look of awe on his face. “Mr. Yan, your reflexes and speed are even better than mine!

“I’m impressed! Truly impressed!”

Yan Feifan smiled faintly and asked, “Mr. Zhang, I’d like to ask, after you were knocked unconscious that day, did you have a dream that felt like it lasted for a very long time?

“The kind of dream that feels so real, like ten days or half a month has passed, but when you wake up, you realize only a day or two has gone by?”

Zhang Chao shook his head. “No!

“I don’t remember having any dreams. My vision just went black, and when I woke up again, I was shocked to find out that two days had passed.”

Yan Feifan had been observing Zhang Chao’s micro-expressions and found no signs of him lying. He knew in his heart that his own experience during his coma was probably unique and unreplicable.

Yan Feifan continued to ask, “Did today’s tests reveal any problems?”

Zhang Chao shook his head again. “No! I’ve had an MRI, a CT scan, cerebral angiography, an EEG, and some kind of brain current mutual inductance test. None of them showed any issues.

“Honestly, I’m not sick at all. My family is just worrying for nothing!”

Zhang Chao said in a somewhat frustrated tone, “I was just hit, and my brain just suddenly clicked. I just got smarter, that’s all.

“If a genius like you, Mr. Yan, can exist, why can’t I become smarter too?”

Yan Feifan chuckled softly. “Your family is just looking out for you. At the very least, your inexplicable weight loss is an objective fact, isn’t it?”

At this moment, from the corner of his eye, Yan Feifan noticed an open hardcover notebook lying on the bedside table. Half a page was covered in numbers.

He glanced at it and asked, “Pi?”

Zhang Chao gave a hum of affirmation. “This memory of mine came so suddenly, I’m afraid I might just lose it as suddenly one day.

“When I have nothing to do, I write down Pi to verify if my super memory is still intact.

“Mr. Yan, I’ve already memorized it up to the forty-eight thousandth digit.

“How many digits can you memorize?”

Yan Feifan casually picked up the notebook and flipped through it as he replied, “I’ve only memorized the first thousand digits. I don’t need to recite these numbers to prove myself…”

Suddenly, he keenly noticed a pattern. Every five or six digits, a specific stroke of the number written in the notebook was noticeably heavier and thicker.

Yan Feifan flipped through several pages in a row, and the numbers written on them all confirmed this pattern. He set down the notebook and extended his hands.

“Mr. Zhang, place your hands on mine. You don’t need to think about anything, nor do you need to exert any force.

“Just rest your hands on mine…”
