Lu Ze said, "That shouldn't be possible. Her period has only been over for less than two weeks. Dad and Mom, I'm going to send Yuning back home to rest first."

Princess Pingrou said, "If you're not pregnant, maybe you caught a cold from the alternating cold and heat of autumn. You should get some rest."

Qi Yuning bowed weakly and said, "Dad and Mom, I'm leaving first."

Qi Yuning leaned on Lu Ze's arms and walked out of the dining room. She could no longer walk, so Lu Ze carried Qi Yuning on his back.

Qi Yuning was at Lu Ze's side, leaning her head against his shoulder and saying, "It's so uncomfortable."

Lu Ze said, "You must have caught a cold at night."

Qi Yuning whispered, "If I caught a cold at night, it's all your fault. It's all your fault for making trouble while bathing at night."

Lu Zelian blamed himself: "It's my fault."

After Qi Yuning returned to her room and lay down, she said to Lu Ze, "State affairs are very busy. While I'm sick, you should go sleep in the next yard. Don't let me catch your illness."

Lu Ze reached out and touched Qi Yuning's forehead and said, "How could someone get sick so easily?"

Qi Yuning instructed Lichun, "Go tell Ali to tell Lingling to stay away from me. If Lingling cries and wants to see me, try to give her something to eat to coax her away from me."

Qi Yuning was afraid that the disease would be passed on to Lingling.

The beginning of spring is the response.

Lu Ze went outside and asked Deqing, "Why hasn't the imperial physician come yet? Go and get him here!"

Deqing responded repeatedly.

Qi Yuning in the room said, "It's just a cold. There's no need to call the imperial physician. It's not good for this minor cold to be known to everyone. I'll drink a bowl of brown sugar ginger tea and take a nap. Maybe I'll feel better tomorrow. Turn off the lights and go to bed. I'm so tired."

Seeing Qi Yuning's weak face, Lu Ze said, "Okay."

Lu Ze lay down beside Qi Yuning, holding Qi Yuning in his arms, patting Qi Yuning's back gently, and Qi Yuning fell into a deep sleep.

"Mom, I'm so cold, so cold!"

After a while, when Lu Ze was about to fall asleep, he heard Qi Yuning's mumbling.

Qi Yuning shivered and muttered, "It's so cold, mother, I'm so cold."

Lu Ze got up quickly and called the maid who was on night watch outside to come in. He took out two quilts and covered Qi Yuning with them, but Qi Yuning still felt very cold.

Qi Yuning opened her eyes and looked at Lu Ze in front of her and said, "Lu Ze, I'm so cold, very cold. Cover me with two more quilts."

Lu Ze looked at Qi Yuning and said, "This is already three quilts."

"But it's still so cold, too cold. Where's my fur coat?"

Lichunlian took another quilt and covered Qi Yuning with it, while Jingzhe went to get a hot water bottle and handed it to Qi Yuning.

Qi Yuning was still shivering with cold even while holding the hot water bottle.

Lu Zelian ordered Deqing to invite the imperial physician as soon as possible. It was not September yet, so he would not feel cold even if he covered himself with four thick quilts and had a hot water bottle.

Lu Ze went over and held Qi Yuning's hand. It was very cold, but her neck was very hot.

For a moment, the courtyard was brightly lit. After waiting for three quarters of an hour, Lu Ze finally saw the late Imperial Physician Chen.

At this time, Qi Yuning no longer complained about the cold, and Qi Yuning's hands were no longer cold, but very hot.

Imperial Physician Chen stepped forward and took Qi Yuning's pulse before asking, "Does the princess have any symptoms? Could I, an old minister, feel her forehead?"

Lu Ze said, "She first became sleepy and had a headache, then vomited. Later, she said she felt very cold, and now she has a high fever. I've never seen anyone have such a high fever."

Imperial Physician Chen reached out and touched Qi Yuning's forehead, a bead of sweat forming on it. He asked, "Did the princess go to Lingnan these days?"

Lu Ze said, "She has never left Shengjing City."

Imperial Physician Chen said to Lu Ze, "Your Highness, I suspect the princess has been infected by the miasma from Lingnan!"

Lu Ze frowned and asked, "Poisonous miasma?"

Imperial Physician Chen nodded and said, "Malaria is also known as malaria. The princess is very likely suffering from malaria."

Lu Ze stood up from the bed, his brows furrowed. "How could it be malaria?"

Imperial Physician Chen said, “The Treatise on Malaria records that the onset of malaria begins with the hairs, followed by stretching and yawning, shivering, trembling chin, and pain in the waist and spine. When the cold subsides, heat appears both inside and outside, with a splitting headache and a thirst for cold drinks.

The princess's symptoms are exactly the same as those of malaria."

Lu Ze clenched his hands and said, "Prescribe the medicine quickly."

Imperial Physician Chen sighed and said, "Your Highness, malaria is difficult to treat. Although there are many prescriptions recorded in medical books, most of them are useless. Princess Xu died from malaria after suffering for more than two years without treatment."

Lu Ze's peach-blossom eyes were filled with resentment. "Now you're still not treating her and you're saying the medicine is useless. She's dead. I'm afraid your career as an imperial physician has reached its limit, right? If anything happens to Princess Qi, you'll pack up and leave the Imperial Hospital!"

Chen Yuyi knelt down in panic. Lu Ze had always been good-tempered, and this was the first time Chen Yuyi had seen Lu Ze so angry. He kowtowed and said:

"Don't worry, Your Highness. Although these symptoms strongly resemble malaria, it could be something else. Even if it is malaria, I will do my best to cure you."

After saying this, Imperial Physician Chen knelt down and left. When he reached the door, he wiped the cold sweat from his forehead. Malaria has always been difficult to cure.

Nine out of ten people who were infected with malaria would not survive. Even if there were one or two who managed to survive, they would never recover and would be troubled by malaria for a long time.

After Imperial Physician Chen left, Lu Ze held Qi Yuning's hand. Qi Yuning looked at Lu Ze with her eyes slightly open and said, "This cold is really severe. My hands and feet hurt so much, it feels like a hammer is hitting them with nails."

Lu Ze didn't dare tell Qi Yuning that it was malaria. He just held Qi Yuning's hand tightly and said, "Drink the medicine later and have a good sleep. You will be fine after you wake up."

Qi Yuning nodded lightly and said, "It's so uncomfortable. You really can't act silly at night from now on."

Lu Ze held Qi Yuning's hand tightly and said, "Well, I won't mess around anymore."

Qi Yuning felt extremely uncomfortable and vomited for a long time before the maid came with medicine. Lu Ze fed Qi Yuning the medicine. Qi Yuning took the bowl and drank it all in one gulp. She felt very uncomfortable and almost fell asleep.

Lu Ze lay beside Qi Yuning, holding Qi Yuning's waist tightly, but he felt that Qi Yuning's clothes were soaked due to the high fever and sweat.

Lu Ze had no choice but to help Qi Yuning change her clothes, but soon her clothes were soaked again and it took a lot of effort to calm down.

When Qi Yuning woke up, it was already noon. She stretched lazily.

Li Chunlian stepped forward and asked, "Princess, how are you?"

Qi Yuning said: "I took the medicine last night, and now I feel much better. There is nothing serious."

Qi Yuning heard a voice coming from the door, looked over and saw it was Lu Ze, and asked, "You didn't take a day off today, why are you back?"

Lu Ze looked at Qi Yuning in front of him, his heart sinking to the bottom. He went to check the medical books in the palace this morning, and Qi Yuning's symptoms were exactly those of malaria.

Seeing Lu Ze's strange look, Qi Yuning chuckled and said to him, "Don't worry about me. It's just a minor cold. I feel much better now."
