As night falls, the lanterns of the Qiao Mansion are hung high, emitting a soft light.

The carriage stopped in front of the mansion gate. Seeing no movement inside the carriage, the accompanying nanny called out softly, "Miss, we're home."

However, there was no response from inside the car. The nanny felt nervous and hurriedly lifted the curtain to check. She saw that Qiao Heyuan was pale, her eyes were closed, and she was unconscious.

"Someone come quickly! Miss Qiao has fainted!" the nanny shouted loudly.

The maids in the mansion rushed over upon hearing the noise and hurriedly carried Qiao Heyuan out of the carriage. Her body was weak and powerless, as if she had no life.

"Hurry! Go find a doctor!" the housekeeper of the Qiao Mansion ordered hurriedly.

Qiao Sanhe was in his study when he heard the noise coming from outside the yard. He put down the book in his hand and walked out of the study slowly.

When he saw his granddaughter's frail appearance, he panicked and immediately ordered, "Quick, go to Baolin Hall and ask Doctor Hong to come."

For a moment, the Qiao Mansion was in chaos.

The servants were busy calling for a doctor, while the maids nervously gathered around Qiao Heyuan's bed, anxiously waiting for the doctor to arrive.

When Mrs. Yang, the eldest lady of the Qiao family, learned that her daughter had fainted in the carriage on the way back home, she rushed over anxiously.

Seeing his daughter lying unconscious on the bed with cold hands and feet, he was so scared that he kept complaining.

"This child just doesn't want to stay quietly in the mansion. He insists on running to places like the porridge factory and mixing with those filthy disaster victims. Maybe he caught some unclean disease from there."

As Yang spoke, she glanced at her father-in-law Qiao Sanhe with a reproachful look.

When it comes to loving his granddaughter, Qiao Sanhe is indeed very caring and always complies with his little granddaughter's wishes.

However, in the eyes of Yang, the mother, she hoped that her father-in-law would take advantage of his official position in the court to find a good marriage for her granddaughter, which was the most important thing.

Her eyes revealed her heartache and worry for her daughter, as well as her dissatisfaction and helplessness towards Qiao Sanhe.

After Hong Zhengxuan returned from the Imperial Hospital, he and two apprentices were busy wrapping pills for removing dampness and clearing heat in Baolin Hall.

"Master, can these pills really help the disaster victims in the south of the city?" an apprentice asked curiously.

"Of course," Hong Zhengxuan replied with a smile, "These pills can clear away heat and dampness, and will be of great help to the victims."

This afternoon, the Xingyuan Marquis Mansion specially sent someone to order two hundred pills for removing dampness and clearing heat to help the disaster victims in the south of the city relieve the suffering caused by dampness and heat.

At this moment, several people quickly started making pills, busy pounding and grinding the medicine, and then carefully rolling it into pills.

Just then, there was a sound of horse hooves in front of the clinic. A carriage stopped in front of the door and the servants of the Qiao family hurried in.

"Doctor Hong, it's great that you're here. Please follow me back to the Qiao Mansion. Our daughter has suddenly fallen ill."

When Hong Zhengxuan heard that Qiao Heyuan was ill, he immediately handed the work at hand to his apprentice, "You continue to wrap the pills and make sure the quality is guaranteed. I'll go to the Qiao Mansion first."

Then he quickly packed up his medicine box, got on the carriage, and went with the servants of the Qiao Mansion.

In the carriage, he asked the servants in detail about the girl's illness, and his expression gradually became solemn.

"Do you have symptoms such as fever or cough?" asked Hong Zhengxuan.

"No, Doctor Hong. The young lady fainted in the carriage after returning home from an outing today. I heard from the nanny in the courtyard that she has not woken up yet and her body is cold." The servant replied.

Hong Zhengxuan nodded, having formed a preliminary diagnosis in his mind. "Don't worry, I'll treat the young lady first when we get to the Qiao Mansion."

The carriage stopped in front of the Qiao Mansion. Hong Zhengxuan hurried into the mansion carrying a medicine box. The nanny who had been waiting for a long time quickly took him to the courtyard where Qiao Heyuan lived.

As soon as he entered the room, he leaned over and carefully observed Qiao Heyuan's condition, and skillfully applied acupuncture to her acupoints.

After a careful diagnosis, Hong Zhengxuan found that she had no signs of poisoning, but Qiao Heyuan still looked drowsy, as if she was half asleep and half awake.

"Doctor Hong, what happened to He girl?" Qiao Sanhe asked anxiously, his tone full of worry. "If you need any precious medicinal herbs, just tell me and I will send someone to find them immediately."

He was well aware of Hong Zhengxuan's superb medical skills. Seeing him frown slightly, he realized that his granddaughter's illness was probably serious.

Hong Zhengxuan had a solemn expression on his face and pondered for a long time, shaking his head and nodding from time to time, which made everyone in the room very anxious.

After a while, he sighed and said, "It's incredible. Miss Qiao's symptoms are similar to poisoning, but the silver needle can't detect any poison."

"Poisoned?" Qiao Sanhe was shocked. "How could she be poisoned? She only went to the porridge factory to distribute porridge today. Logically, she shouldn't have come into contact with anything poisonous."

Hong Zhengxuan turned to look at Qiao Heyuan, who was lying weakly on the bed. "First, I'll prescribe a warming and tonic medicine for Miss Qiao. She's been sweating profusely and needs to replenish her energy to prevent her from collapsing."

After writing the prescription, Qiao Sanhe hurriedly ordered someone to get the medicine.

Seeing that Hong Zhengxuan was also helpless, Yang sat helplessly beside the bed, looking at her daughter who had not woken up yet, tears falling down her face.

Her husband Qiao Mingyuan was sent to the south on business and was not around. This sudden change caught her off guard and she was full of worry, fearing that something might happen to her daughter.

Hong Zhengxuan was also in a state of confusion at the moment. Although he knew that doctors should treat patients with a parental heart, he felt unprecedented panic at this moment.

He suddenly longed to devote all his life's knowledge just to ensure Qiao Heyuan's safety.

"Master Qiao, has Miss Qiao been traveling back and forth between the porridge factory in the south city and the Qiao Mansion these days?" Hong Zhengxuan asked.

"That's right." Qiao Sanhe replied.

"Then I'll go to the porridge factory immediately. If anyone there has similar symptoms, it might be easier to find the source of the disease." Hong Zhengxuan said as he picked up the medicine box and prepared to leave.

"I'll go with you!" Qiao Sanhe said, and followed out hurriedly.

"Master Qiao, it would be best if you keep a close eye on Miss Qiao's condition at home. If there are any changes, please inform me immediately."

Hong Zhengxuan was worried that Qiao Sanhe was old and weak, and it would be troublesome if he fell ill.

Furthermore, when he caught a glimpse of Madam Yang, he felt that she was not someone who could remain calm in a critical moment. Therefore, it seemed safer for Qiao Sanhe to stay in the mansion to take charge of the overall situation.

Qiao Sanhe looked at the chaotic scene in the house and heard his daughter-in-law crying, and immediately understood Hong Zhengxuan's intention.

"Okay, go prepare the car and send two more people to go with you." Qiao Sanhe decisively gave orders to the servants.

At the same time, from the tents around the porridge factory in the south of the city, low groans of pain were heard from time to time.

Ding Xinwan went to several tents where the elderly, the weak, women and children lived, and delivered some clothes. When she turned to leave, her wrist was grabbed by an old woman with white hair.

"Why do you want to... harm me?"

The old woman had a look of pain on her face, and her bony hands tightly grasped Ding Xinwan's arm, pinching her so hard that it hurt.
