The concubine is a man, and the illegitimate son of a divine physician has a spatial ability.

Then, Yin Gui couldn't help but nag, "Zijin, you must remember this: this stuff is extremely poisonous. You must never touch it again." He sighed, then continued, "However, in my opinion, the person who used this drug is even more ruthless. To devise such a harmful method, it must be someone very close to you. After all, this drug only becomes truly effective after years of use. Alas… the human heart is unfathomable!"

Yin Zijing nodded, his brows furrowed slightly, and said with a hint of anxiety, "Third Uncle, please keep this medicine safe for me. I need to go back to the manor now. Ruhe's medical skills are quite good; she can temporarily take my place as a doctor. As for this harmful substance, I must deal with it personally when I get back." With that, he turned to leave.

Yin Gui quickly grabbed his sleeve and asked anxiously, "Zijin, don't rush off. You have to tell your third uncle what exactly happened." His face was full of worry and confusion.

Yin Zijing stopped and turned to look at Yin Gui, a hint of worry flashing in her eyes: "He recounted the whole story as quickly as possible."

Upon hearing this, Yin Gui quickly said, "It is Princess Guan. This matter cannot be taken lightly. Zijing, you go back first and take care of the medicine."

I'll go back to the Yin residence tonight to see your brother. He sees His Highness the Crown Prince often, so I'll have him arrange for the Crown Prince to come to the clinic. You can talk to him about this then. After all, the eldest princess and the Crown Prince are siblings. I'll also have the Crown Prince inquire with the Empress..."

Yin Zijing nodded and said, "Alright, I'll leave this matter to Third Uncle. I'll head back now."

After bidding farewell to Yin Gui, Yin Zijing hurriedly boarded a carriage and headed towards Fu'an Temple. The closer they got to Fu'an Temple, the more snow accumulated on the road. The weather worsened, and snowflakes began to fall again. Fewer and fewer pedestrians were on the road, until finally, only one carriage was struggling to move forward in the wind and snow.

Fortunately, A-Tian took good care of Yin Zi-Jin, and she didn't suffer too much. Upon arriving at Fu'an Temple, A-Tian immediately carried Yin Zi-Jin to the princess's residence.

After a lengthy and complicated announcement, Yin Zijin, with her bound feet still bound, took Ah Tian's arm and walked demurely into the house, showing no lack of proper etiquette or manners.

Upon seeing the princess, Yin Zijin immediately kowtowed and paid her respects. Sheng Muling helped Yin Zijin up and quickly said, "The ground is cold, please sit down! Zijin. You look so worried, is something important?"

Sitting at the lower end, Yin Zijin hurriedly said, "Princess, please take out the gold bracelet on your wrist and the incense burning in the incense burner!"

Sheng Muling waved her hand, and soon the maids and eunuchs brought out the items. Yin Zijing looked around, and Sheng Muling quickly dismissed the servants, saying, "Zijing, just say what you have to say!"

Yin Zijing said, "Your Highness, I have had my third uncle examine it carefully, and there is indeed a problem with the medicine. The pills, the gold bracelet, and the ignited powder, when mixed together, become a deadly poison, and it was this that caused your miscarriage."

Not only that, the princess has been unable to conceive for many years, also because of these things. This poison is extremely potent, and the princess has been using it for many years, which will inevitably make it difficult for her to have children in the future, and she will most likely be unable to conceive. This is also the reason why the princess has been unable to get pregnant again after her miscarriage..."

Upon hearing this, Sheng Muling's face turned deathly pale, and tears streamed down her face like a burst dam, like pearls falling from a broken string, unstoppable. She gently wiped her eyes with a handkerchief, but she appeared flustered and helpless, as if she had lost her soul and was completely disoriented.
