Gu Yun was a full two decades older than Yun Qing. If he were to kneel down in front of Yun Qing like that, Yun Qing would feel like he was shortening his lifespan.

She didn't even have time to think about how Gu Yun found out that Mr. Yu was away from the mansion before she immediately went to help him up.

However, this small gesture led Gu Yun to mistakenly believe that she was refusing.

He said somewhat urgently, "Grand Tutor Li, I know this request is presumptuous, but I really have no other choice, so I've come to you for help..."

Gu Yun and his wife were childhood sweethearts, but unfortunately, she died young. Her health was poor after giving birth, and she passed away at a young age. Gu Yun never remarried and devoted himself to taking care of their only son, pouring almost all his energy into him.

Later generations praised him for his deep affection and devotion, and many literati even used him as a model in their poems. Only now does Yunqing truly understand this.

She sighed, "Lord Gu, I didn't mean to refuse. I'm just a junior. Let's sit down and talk things over. There's no need for such a grand gesture."

Yun Qing's attitude was gentle, and her expression was neither humble nor arrogant. Gu Yun looked up and realized that he had misunderstood. He felt a little ashamed and said, "I'm sorry, I was too anxious. I hope the Grand Tutor will forgive me."

Facing someone younger than himself, Gu Yun addressed her as Grand Tutor smoothly. He trusted Yun Qing and did not think she was a treacherous minister. Or, on a deeper level, he trusted the Li family's traditions.

The departure of generations of loyal and devoted individuals cannot possibly produce a treacherous and disloyal person.

Yun Qing poured him a cup of tea and said gently, "Master Gu, calm down. Please tell me your story. Uncle Jiang has already gone to call Mr. Yu. We can go and see him now."

Yun Qing didn't ask him where he got the information. She guessed that he probably targeted the little tyrant.

They had only mentioned Gu Yun not long ago, and the little tyrant is always very perceptive. There's no reason why he would keep the news so tightly under wraps before leaving home, only to have it leaked at this crucial moment.

It's good that they can win people's hearts, but I didn't expect them to use such tactics against her so quickly.

Yun Qing was both amused and exasperated.

Gu Yun was moved to tears, and now she looked up to Yun Qing even more: "My son's illness is no secret. He was born weak and we have been trying to raise him for so many years, but it hasn't been very effective. Recently, the weather has been changing a lot, and he has started to have relapses again. He still hasn't woken up. I'm so worried."

"An illness congenital? That is indeed difficult to treat." Yun Qing reassured him, "I'll ask Mr. Yu to take a good look at him; there's bound to be a way."

Da Xi's medical technology is relatively backward. Yun Qing has no knowledge of this area except for some common sense, so she can't help at all. She can only leave the professional matters to the professionals.

“It’s alright. The fact that the Grand Tutor is willing to lend a helping hand is already a great act of kindness. I will accept whatever the outcome may be.”

Gu Yun had a premonition that his son might not make it through the year. It was lucky that he could find the Qishui Yu clan. If not, it was fate, and he couldn't force it.

Mr. Yu, being good-natured, showed no displeasure at being summoned at this hour. He looked at Yun Qing and asked, "Where is the patient you mentioned, young master?"

Yun Qing said, "Then we'll need Lord Gu to lead the way. I'll go with you and see how things go first."

Yun Qing wasn't sure if her common sense would come in handy, but following along was always the best course of action.

Mr. Yu picked up his medicine box: "Let's go, there's no time to lose."

Gu Yun was even more moved by their decisive attitude. Fortunately, the carriage he had come in was large enough to accommodate three people.

After Mr. Yu got in the car, he and Gu Yun sat on one side, leaving the other side for Yun Qing.

Yun Qing was moved and smiled at him.

The carriage arrived at the Gu family residence quickly. Although Gu Yun was in a hurry, he still remembered etiquette and did not urge them. He silently led the two into the depths of the courtyard.

As night deepened, the light was still on in that place, and one could hear servants whispering timidly, closely watching the situation inside.

Upon seeing Gu Yunlai, they hurriedly bowed and greeted him: "Master."

Gu Yun waved his hand: "Wait outside."

After clearing the room, you can see Gu Yun's son's bed behind the screen. He is lying on the bed with his eyes closed and his face is visibly pale. He should be the same age as Yun Qing, but he looks much thinner and weaker, like a fifteen or sixteen-year-old child.

Yun Qing finally understood why he couldn't live past nineteen, something that might be hard to explain even in modern times.

Mr. Yu's brows were also furrowed tightly. He stepped forward to take Gu Yun's pulse carefully, and Gu Yun watched from the side, not daring to breathe too loudly.

After a long while, Mr. Yu sighed softly, "There is still a chance, but the medicinal materials that the young master needs are very precious. Lord Gu will have to put in a lot of effort."

"Okay, okay, as long as there's a chance for things to turn around, I don't care about anything else."

Whether it's troublesome or not, that's not what Gu Yun cares about. Over the years, he has spent just as much time and effort on his son as he does on this. Any opportunity is a good thing.

Mr. Yu nodded. Seeing that he seemed to be accepting the treatment well, he walked over, picked up a pen and ink, wrote a prescription, and handed it to him, instructing, "The young master will wake up by noon tomorrow at the latest. Please gather the medicine listed above as soon as possible and decoct three doses a day. I will come back to check the young master's pulse in half a month and then change the prescription."

Gu Yun nodded repeatedly, taking his words to heart, and then saw the two of them out.

"I am deeply grateful for the kindness shown to the Grand Tutor and the Master. I hereby promise that if there is anything I need to do in the future, I will do my best to help as long as it does not violate my promise."

Gu Yun is a grateful person, and if these two hadn't been willing to come, he really wouldn't have been able to get things done today.

Yun Qing helped him up and said with a smile, "Don't talk about repaying him. As long as Lord Gu does his job well, that is the best way to repay him."

Gu Yun has done so many good deeds, yet Heaven doesn't reward him at all. It's truly blinding. Yun Qing might not have agreed to this if it were anyone else, but she had a very good impression of this virtuous official who would be remembered in history, which is why she agreed.

So sometimes, everything really does depend on fate.

Once inside the carriage, Yun Qing brought up a matter with Mr. Yu: "Mr. Yu, I've noticed that you seem to be planning to travel the world practicing medicine and saving lives?"

While taking his pulse, Yun Qing saw a light shining in Mr. Yu's eyes—a passion for medicine. He clearly wanted to research new illnesses, but he spent most of his time in the Li residence. Yun Qing wondered if the Li residence was keeping him confined.

Otherwise, why would the first thing he did after fulfilling his promise was to travel around practicing medicine?

Mr. Yu was surprised: "Why would you think that way, young master? If it weren't for leaving home to help, the Yu clan of Qishui would have been wiped out long ago. Staying is what I should do."

Whether or not it should be done is not important.

Yun Qing patiently asked, "I just want to ask you, would you like to spread your medical knowledge to the world?"
