Almost no one noticed the young, unfamiliar eunuch beside the Crown Prince, but almost doesn't mean completely unnoticed; Yinzhen did notice.

Then Yinzhen was a little confused. The Crown Prince was in a bit too much of a hurry. If you don't want people to know, then don't do it in the first place. Although he did it secretly, there must have been traces left behind.

Now that Emperor Kangxi is seriously ill, at a critical moment, the Crown Prince still has the mood to play around with women.

If Emperor Kangxi knew this, Yinzhen would shudder.

Another day passed, and the Crown Prince received news from the imperial physician that Kangxi's condition had worsened. The Crown Prince privately inquired with the imperial physician, who said that at this point, there was basically no hope of recovery.

That afternoon, the Crown Prince had a wild and silly time with Lianxiang in his study twice.

That evening, the Crown Prince went to guard outside Kangxi Gate with a sorrowful expression.

At this moment, Su Peisheng brought Jinji Shuangna over.

After receiving the Golden Rooster Frost, Yinzhen immediately summoned his eldest brother and other brothers, along with a group of court officials, to the courtyard where Kangxi was recuperating.

Upon seeing so many people arrive, the Crown Prince frowned and said, "Father needs to rest quietly. What should we do if you all come here and disturb his recovery?"

At this moment, the eldest prince spoke up: "Your Highness, my fourth brother has obtained a medicine that can cure malaria, so we have come here."

The crown prince was startled upon hearing this.

How could that be?

Malaria is difficult to treat, so how could there possibly be a cure?

The Crown Prince looked at Yinzhen with a serious expression: "Fourth Brother, is what Eldest Brother said true?"

Yinzhen said, "It's only a possibility; as for whether it can truly cure my brother, I can't guarantee it."
