Regarding malaria, the character "疟" (malaria) was already recorded in the oracle bone inscriptions of the Yin Dynasty.

Of all infectious diseases, malaria is the one most thoroughly documented in medical texts.

This shows just how much of a headache this infectious disease is for doctors.

This disease was already difficult and troublesome to treat, and the fact that the patient was Emperor Kangxi made them even more constrained, as many potent medicines could not be used at all.

Yinreng was the first to receive the news. As the crown prince, he was responsible for the emperor's serious illness and his inability to review memorials or attend court. He had to step in.

Seeing Kangxi suffering from illness, Yinreng felt extremely distressed.

He did not become estranged from Emperor Kangxi after he got married and had children.

The father and son had a very deep bond, so when Yinreng felt sad, it was always on his face.

His eyes reddened, but he held back his tears, afraid that outsiders would misunderstand that Kangxi was in poor health and was forcing himself to be strong, which would make Kangxi feel very distressed.

"Baocheng, I'm fine. I survived smallpox back then and suffered numerous surprise attacks on the battlefield, sustaining countless injuries, both major and minor. This mere chills and fever will be nothing to me," Kangxi said confidently.

Inspired by Kangxi's exhilarating mood, Yinreng said, "I will come to see you every day after court. Ordinary memorials are fine, but for some important military matters, I must listen to you."

Kangxi gripped the blanket tightly, using his strong willpower to control the frequency and amplitude of his body's trembling.

"Alright, I'll make the decision for you." Kangxi said, "Fever and chills are contagious, so don't let your brothers come to see me. The children in Yuqing Palace are still young, so you should also keep them away from them."

After seeing Kangxi carefully instructing Yinreng and prescribing medicine to suppress the symptoms, the court physician reassured Kangxi and corrected him, saying, "Your Majesty, fever and chills are different from other infectious diseases. It is caused by mosquito bites."

Emperor Kangxi frowned and said, "Everything must be prepared for the worst. It's one thing for others, but what about Hongzhao and his children? If something happens to them, who can bear the responsibility?"

Thinking about the ages of Yinreng, Hongzhao, and Hongsheng, Kangxi unconsciously thought of himself twenty years ago.

In his youth, the children in his harem always struggled to gain a foothold. The early death of their offspring not only saddened the concubines who were mothers, but also caused him, as their father, immense heartache.

Emperor Kangxi did not want his beloved eldest son to suffer such pain and despair again.

The judge shut his mouth and stopped talking, blaming him for being so talkative and meddling in the affairs of the royal father and son.

The father and son have a deep bond and worry about each other; why is this imperial physician getting involved?

Yinreng was being constantly nagged and instructed by Emperor Kangxi. He felt uncomfortable looking at Kangxi, but he was unwilling to show weakness in front of him. After making a long story short, Yinreng took the memorials and went to the side hall of the Qianqing Palace to review them.

The physician gave Kangxi a few acupuncture treatments, which temporarily made him feel better.

People who are ill often have very strong emotions.

Emperor Kangxi, who was usually stern and unsmiling in front of his subordinates, boasted to the chief judge, "My crown prince is both filial and capable. Ten sons from other families combined cannot compare to my one."

The court judge automatically shut down his hearing; he couldn't hear anything, not even the emperor's boasting.

The imperial physician kept his head down, staring intently at the prescription. The other imperial physicians had all left, and Liang Jiugong followed to watch the medicine being prepared. Kangxi couldn't very well talk to the palace maids serving him.

"Judge Kangxi, what do you think of my Crown Prince?" Kangxi asked the judge.

The judge was quite helpless as Emperor Kangxi relentlessly pressed him for answers.

He feigned ignorance and said, "Your Majesty, the Crown Prince has a rosy complexion, bright eyes, a steady gait, and calm breathing; he is in very good health."

Emperor Kangxi was amused: "Your whole family is so cunning. Ever since your grandfather, you've always talked like this. I'm not a man-eating tiger. Even when I chat with you occasionally, you're always so careful. No wonder Father Emperor once said that once you become emperor, you're lonely and isolated. He's right."

The judge pretended to be a block of wood and did not respond to Kangxi.

Kangxi knew that it was right for him not to respond, otherwise why would his family always be the ones making the judgments?

Their excellent medical skills passed down through generations are one thing, but more importantly, they never participate in factional struggles, only obey the emperor's orders, are tight-lipped and not conceited, which puts the emperor at ease.
