Come to think of it, I had never seen a medical text in this world that dealt with heart attacks.
If not for his memories as a modern person, Yuseong, like Doctor Yang, wouldn't have even known the method of breathing air into someone.
However.
It seemed the girl's heavenly fortune had not yet run out.
Because he was here.
"Oh dear, it seems even my master's secret method is not working. It is a pity, but this child has passed away."
"Oh, no!"
At Doctor Yang's declaration, the girl's father, all hope lost, collapsed to the ground as people offered words of comfort.
Just then, someone in the crowd shouted.
"Hey, what are you doing right now?"
Yuseong had settled down on the girl's left side and was pressing down on her chest with his hands clasped together.
Her body had already begun to go through puberty.
Each time Yuseong put his weight into it, the girl's budding breasts sank in and rose back up repeatedly.
To the people who didn't know about chest compressions, it looked as if he was doing something wicked to a dead body.
"Have you ever seen such a madman! How can a man who calls himself a doctor commit such a shameless act in broad daylight! On a dead child, no less!"
Doctor Cha roughly grabbed Yuseong's shoulder, only to be sent stumbling.
"Oof!"
Yuseong, who had shrugged off his hand, shouted at the people.
"This is a treatment! I have to perform chest compressions! She will die if blood doesn't reach her brain! Every second counts, so do not interfere!"
"This bastard, still!"
Doctor Yang recalled what his master had taught him in the past about people whose pulse suddenly stopped without any particular external injury.
"Master, does that mean you can even save a dead person by blowing your breath through this bamboo tube?"
"To be precise, they are not dead. Even if a person's heart suddenly stops, they are not completely dead. If you breathe into them for a while, those who are not fated to die may be revived."
"Is that really true? Master, have you ever saved someone who was dead—no, whose heart had stopped?"
"Yes, I have seen a total of ten such patients, and I have saved one of them with that method."
Such a conversation suddenly came to mind. Baek Yuseong's attitude and expression looked serious.
It did not look like he was molesting the patient.
His clasped hands were not kneading her chest; just as he said, he was using the palms of his hands to press the area near her heart in a steady rhythm.
It might be a crazy thought, but he came to the conclusion that Yuseong, not his master, might be right.
He stopped Doctor Cha, who was rolling up his sleeves beside him.
"Wait a moment, Doctor Cha."
"What do you mean, wait? Even after Doctor Yang said she was dead, this bastard is still committing this outrageous act, isn't he?"
"Just a moment, let's just watch for a moment."
Despite Doctor Yang's intervention, the people stared at Baek Yuseong with disapproving looks.
The girl's father didn't know what to do.
And at the entrance of the Luoyang Medical Center, there was another pair of eyes watching Baek Yuseong, one hand gripping the hilt of a sword engraved with a fan.
She was a beauty, impressive with her cold gaze that seemed filled with the resolve to cut Yuseong down if he tried any funny business, and the deep, dark shadow cast beneath it.
Unaware of this fact, Yuseong, thanks to Doctor Yang stepping in, was able to continue the chest compressions without any more physical interference.
Although he was in a position to put his full weight into it, Yuseong himself couldn't be sure if he was compressing the heart with the correct rhythm and depth as he had been taught.
He had only stepped forward with the hope that a person he could save would not die before his eyes.
'Please, wake up. This might be a game, but to me, this is reality now. I don't want to see someone die right in front of me!'
He pressed deep on the ribs to compress the heart.
He had learned that they might break if he was unlucky, but that was better than dying.
And even if they broke, he could treat them.
In theory, the blood pumped from the heart should be heading to the brain, but the unconscious girl's complexion showed no change at all.
'Is it not working?'
No. It was too early to give up.
He wasn't sure how much time had passed, but it hadn't been long.
He again pressed down on her torso to compress the heart, then lifted his torso up, repeating the motion.
According to what he'd learned, if you started chest compressions immediately after a heart attack, the chances of survival were higher than if you didn't, and the probability dropped as time went on.
Although some time had been wasted, Doctor Yang's bamboo tube treatment hadn't taken long, so the golden time probably hadn't passed yet.
Thinking so, Yuseong continued the chest compressions for a while without giving up.
"Keoheok...!"
The girl's pained, contorted expression eased slightly, and at the same time, a deep breath finally burst out.
"Hah... It worked..."
Yuseong let out a sigh of relief.
He had succeeded in his first-ever CPR.
The doctors and patients who had watched it happen live right next to him were flabbergasted.
"A d-dead person came back to life!"
"Doctor Baek Yuseong brought a dead person back to life!"
A small chuckle escaped Yuseong's lips at the people's fuss.
'I told you she wasn't dead.'
The doctors, including Doctor Yang and Doctor Cha, sent him intense gazes, their expressions half-amazed and half-curious.
"My, how...!"
Doctor Cha quickly checked the girl's pulse.
"Her pulse is really beating!"
Regardless of the pulse, just by looking at the girl who was blankly shedding endless tears, no one doubted her return to life.
Now, the doctors scrambled to throw questions at Yuseong.
"What in the world happened? How can you save a dead person by compressing the heart? Is this method also possible for someone who died of old age?"
"Just a moment."
Yuseong first gave a slight bow to the doctors, then checked the girl's condition.
"Are you okay? Does your chest hurt or feel tight?"
"I, I'm..."
Instead of the girl, who couldn't answer properly, her father bowed his head deeply to Yuseong.
"Oh, Doctor, thank you for saving my daughter! I thought something had happened to Eun-seon, and my world truly went dark. Eun-seon, what are you doing? Hurry and greet your benefactor and answer him!"
Only then did focus return to the girl's eyes.
"Ah... My name is Jin Eun-seon. I am deeply indebted to you. Ah, and about what you asked..."
The girl pressed on her chest over her clothes.
Some of the people blushed and turned their heads away.
"For the past few days, my chest has been throbbing occasionally, but I think it's fine now."
It seemed her ribs were fine, too.
Though she looked a bit tired, the girl's now-stable face looked like it would grow into that of a considerable beauty.
"That's a relief. However, the same symptoms could appear again, so you must be careful."
"Then what should we do? Should I bring her back to you, Doctor?"
At the girl's father's question, Yuseong looked around.
All the people and doctors, having abandoned their own consultations, were watching this scene with great interest.
Among them were several who looked like martial artists.
It was only natural, as warriors from the Murim Alliance often visited.
'Is that woman a martial artist, too?'
A beautiful woman in a scholar's attire, incongruously wearing a long sword at her waist, was watching him.
Clear curiosity was visible in her eyes.
'This isn't the time for this. There must be many cases of people dying who could be saved like this. I learned this through education in my reality, so it's better to spread it widely to people. Might as well do something good.'
Yuseong shook his head to clear his thoughts and shouted to the people.
"May I have your attention for a moment."
Looking at the people with questions in their eyes, Yuseong had a servant lie down and taught them the emergency treatment method for a heart attack and its precautions.
People's eyes widened to better remember the chest compression method, and some doctors even brought out writing tools to take notes.
Doctor Cha apologized for what happened earlier and asked a question.
"Ahem, I apologize for misunderstanding. It was such an unbelievable secret method, wasn't it? Since even Doctor Yang had given up, I was certain it was wrong. I apologize once again."
"It's alright. It was an urgent situation, so I couldn't explain properly either."
"Oh dear, I feel so ashamed. So, you're saying that when a heart attack occurs, one doesn't die immediately but because blood isn't delivered to the brain? But to think that you have to take action within a short time of less than half a quarter-hour, this girl was truly lucky."
"That's right. Fortunately, it wasn't too late, so she was able to wake up with her mind intact. You said your name is Jin Eun-seon, correct?"
"Yes. Benefactor."
"I can't be certain, but once a heart attack has occurred, the same symptoms may appear again, so Eun-seon's father, you must remember this and perform chest compressions without delay."
"Yes, I'll keep that in mind. But..."
The girl's father trailed off, cautiously gauging the situation.
"Please, speak comfortably."
"Is it alright if I pass on the secret method you taught us to my servants and family? Since I can't always be by her side..."
"Of course. That's why I revealed this method in front of everyone. If possible, please help it spread to as many people as possible. If emergency measures can be taken in time, a significant number of people who collapse from a heart attack will be able to survive."
"Incredible!"
Doctor Yang said.
"Doctor Baek, you are truly a man of great character. It's embarrassing, but the success rate of the secret method I learned from my master was only ten percent. And yet, I kept it hidden all to myself until today. To think you would reveal such an amazing secret method without hesitation!"
As he was being praised so highly, Yuseong acted modestly before deciding to check the girl's pulse in detail.
He asked for permission, as she had been a patient in Doctor Cha's line.
"Doctor Cha, would it be alright if I examined this child? If you're uncomfortable with it..."
"Not at all, isn't she a patient you saw? Of course, you should see her."
It seemed Doctor Cha wasn't a bad person at heart.
***
The first patient of Yuseong's eleventh examination room was decided to be Jin Eun-seon.
He checked her pulse meticulously, but no particular abnormalities were found.
"There are no particular issues, but it would be good for your health to learn martial arts."
"I will keep that in mind."
Jin Eun-seon sent him an intense gaze, different from when other people were around.
"To be honest, a moment ago, I thought I was dead for sure. You may not believe me, but while I was collapsed, I met a spiritual being."
"...You mean something like a grim reaper?"
"Something similar."
Yuseong wasn't the type to believe in such things, so he figured the girl had seen a hallucination.
"In any case, Doctor Baek Yuseong, you are my benefactor. I, this girl, will pray for you for the rest of my life."
Her attitude seemed sincere.
To have someone pray for him for the rest of her life, it felt good even if they were empty words.
Could this be the joy of treating a patient?
Just as Yuseong felt a sense of pride as a doctor, his vision suddenly went black.
***
A sacred light descended from the sky.
It was just like the beginning of the dream he'd been having every day lately.
'Huh? Why am I suddenly having this dream? Did I fall asleep? Did I pass out from doing CPR earlier? Even if my dantian is broken and I've lost my martial arts, my stamina shouldn't be this low...'
Now it was time for the goddess's voice to be heard.
And just as expected, a voice began to speak.
But its content was different from usual.
[My most beloved child, I planted a seed of divinity in you long ago. However, I did not tell you, as I believed making the seed sprout would be a very difficult task. But you broke through the miraculous odds and finally succeeded. I will cheer you on as you nurture it into a divinity of your own.]
