Su Yan took a deep breath and said seriously, "I know you are worried, but the patient's face has turned bluish-purple, and glucose will not be effective in the short term."

How about this: if any patient experiences any problems after drinking the herbal medicine I prepare, I will take responsibility. Hopefully, you won't have any objections then.

Seeing her stubborn attitude, the train conductor hesitated, after all, Su Yan didn't seem like she was lying.

Su Yan waited a few seconds without receiving a reply, then turned and ran away.

In the current situation, even a second's delay could cost the elderly person their life.

Half a minute later, Su Yan returned with a thermos.

She poured the Chinese medicine into the bottle cap, then carefully lifted the old man's head and fed it to him.

Seeing this, Tian Yu opened his mouth but ultimately said nothing.

The color is that of green tea, and it has a slightly bitter taste when you drink it, with a sweet aftertaste.

After being given a capful of traditional Chinese medicine, the elderly man's complexion gradually returned to normal, and his breathing began to stabilize.

The train conductor exclaimed in astonishment, "Comrade, is your traditional Chinese medicine really that miraculous?"

Su Yan nodded and said, "This is just a traditional Chinese medicine to replenish the body's energy. There will be no side effects, so you can rest assured."

"Excuse me for asking, why do you carry this medicinal water with you?" Tian Yu asked.

His tone was sincere, and his eyes were full of curiosity, completely unlike the sharp and piercing tone he had shown earlier.

Su Yan said calmly, "Because I got lost while collecting herbs in the mountains and encountered a large animal, I was trapped in the mountains for two days. The dry food I brought was not enough to replenish my body's functions. Since then, I have developed this Chinese herbal medicine. I take it with me whenever I go on a long trip. Does Dr. Tian have any objections to this explanation?"

Her last question was barbed and pointed.

Tian Yu coughed lightly and said awkwardly, "I'm sorry, my attitude was bad just now. It was just my instinct as a doctor. Please don't hold it against me."

She wasn't actually that angry, and she could understand Tian Yu's reaction.

"Cough cough cough..."

The old man on the ground suddenly coughed, slowly opened his eyes, and looked at everything in front of him with confusion. "Who are you...?"

"You fainted just now. Do you feel any discomfort anywhere?" Su Yan asked.

The old man took a moment to feel it before shaking his head, "That's all, I'm just a little hungry."

Su Yan took out three White Rabbit milk candies from her pocket and stuffed them into his pocket. Then she put the vegetable bag she had bought before getting on the bus into his hand and said, "If you feel dizzy, eat some candy. Now eat a bun to fill your stomach. Also, there is Chinese medicine in this thermos. It will be good for your health. You can take it and drink it. You don't need to return the bottle."

The old man looked at the still-warm bun in his hand, then looked up at Su Yan and smiled, "Thank you, young lady."

"You're welcome." Su Yan helped him up and sat him back in his chair before continuing, "Grandpa, are you having any difficulties? The train conductor is here, you can tell me what's wrong."

She noticed that the old man was wearing clothes made of very fine material, so his family must be quite well-off. How could he not even be able to afford a meal?

The old man waved his hand and sighed, "It's not a problem. I just accidentally lost my wallet. After buying the train ticket, I had no money for food. I planned to eat when I got to Beijing, but I didn't expect that I'm old and not in good health. I can't even bear this little bit of hunger. I'm really useless."

“You have a heart condition with arrhythmia, so you should be extra careful in your daily life. Try not to go out alone in the future,” Su Yan said. “When we arrive in Beijing tonight, you can ask the train conductor to call home and have them come pick you up.”

"Okay, I understand. Thank you so much."

The train conductor laughed and said, "If you want to thank someone, thank this young lady. It was her miraculous potion that made you wake up so quickly. We didn't have to do much. And this Dr. Tian, ​​he's the one who diagnosed the cause of your fainting."

Tian Yu pushed up his glasses and said, "It was nothing, and as a doctor, I can't just stand by and watch someone die."

Su Yan said directly to the train conductor, "Please take good care of the old man. If you have any problems, come find me and Dr. Tian. I'm going back now."

Upon hearing this, the old man immediately said anxiously, "Young lady, please leave your phone number and name. I'll call you when I get back to thank you properly."

Su Yan stopped and turned around with a smile, "My name is Su Yan. You don't need to thank me. Thank Dr. Tian. He's the one who diagnosed your problem. We'll meet again someday."

After saying that, she left without looking back.

Tian Yu also declined, saying, "I'm glad you're alright. I didn't really help much. Goodbye."

After he finished speaking with the old man, he quickly followed Su Yan.

Su Yan returned to her bed and glanced at the time. It was already 9:30 PM, and she would arrive in two hours.

She took out the last two vegetable buns from her bag, sat cross-legged, and ate them slowly.

She planned to stay in Beijing for no more than three days, so she brought a dark blue handbag containing three sets of clothes, some daily necessities, and some food she bought at the train station entrance that morning.

When Tian Yu returned and saw her there, he instantly breathed a sigh of relief.

Su Yan followed him for a while, watching his emotions change three times in just over ten seconds, and couldn't help but curse him inwardly as crazy!

She felt that Tian Yu was a strange person, especially the way he looked at her, but as long as he didn't seem to have any ill intentions, it was fine.

Tian Yu sat on the edge of the bed, hesitating for a long time, before finally stammering, "Um, Comrade Su Yan, may I ask you a question?"

Su Yan's gaze remained fixed on the menu as she calmly said, "Dr. Tian, ​​this is the third time you've been so intrusive to me in just a few hours. Just say what you have to say."

She really dislikes fussy, mother-in-law-like people.

Tian Yu scratched his head and said, "Can I buy the formula for the Chinese herbal medicine you developed and take it back to study? Of course, the formula is still yours; I just want to buy it and try making it to see the effects."

"Not for sale." Su Yan refused without even thinking.

"I'm genuinely curious, and I definitely don't intend to do anything bad with the Chinese medicine," Tian Yu assured him. "Besides, you know I'm a doctor at Yanjing Hospital. I have a job, and I certainly wouldn't do anything to damage my reputation."

He studied Western medicine and always thought that traditional Chinese medicine was backward, until he saw the effects of the Chinese herbal medicine just now, which he found incredible.

Su Yan closed the recipe book and said without changing her expression, "I'm sorry, if you're so curious, I suggest you learn traditional Chinese medicine before you study it. The medical profession is one of endless learning, isn't it? Besides, I don't know you at all, and I'm not willing to trust a stranger."
