Flowers have fragrance, moon has shade

  And without mentioning how Su Taichang discovered the shocking secret in Qianxi, he was restless for two days and finally found Sun Taichang, the chief physician of the Imperial Hospital, and secretly told him about it.

  "If this matter is exposed... I'm afraid the entire imperial palace will be turned upside down, and the consequences will not be small. Su Taishi also knew that the situation was serious, and bitterly said: "Although I suspect that several of the princesses were poisoned by the lunar root grass, however, I have never seen this kind of grass before, nor do I know where the poison is hidden, it's difficult to find evidence. If my guess is wrong, the crime will also be not small. But if we conceal and don't report it, that would also be a crime of deceiving the emperor... Therefore, I have no choice but to swallow my pride and come to ask for Brother Sun's help."

  "Two years ago, my grandson found an old book in the study that described many rare flowers and herbs, as well as some strange stones that could cure or cause diseases... I was skeptical at first, as most of what was written were things that I, a doctor with decades of experience, had never heard of or seen. However, there are indeed some extraordinary prescriptions passed down among folk doctors, and families like ours who have been in the medical profession for generations also have their own secrets that aren't shared with outsiders. I wouldn't dare to think that I know everything." Dr. Sun said slowly, noticing Dr. Su's puzzled expression, he nodded his head in confirmation, "But now I believe half of it, because what you said about the Moonroot Grass is indeed recorded in that book. However, like you, I've never seen this herb before, so it's hard to make a judgment."

  "Why don't you, Brother Sun, find an opportunity to take his pulse personally? If it's confirmed to be poisoning, then we can make plans."

  "It can't be helped."

  The two of them agreed that next time they would have Dr. Sun go first to make a diagnosis and see if it was really as Dr. Su said, with symptoms of poisoning, before making further plans.

  On the other hand, Gao Bin started as Governor of Guangdong in the sixth year of Yongzheng and was transferred to Zhejiang, Jiangsu, and Henan provinces over the next few years. In the ninth year, he was promoted to Vice Minister of the Yellow River Conservancy, and this year, he was also appointed as the Salt Administrator of Lianghuai and concurrently served as the Weaving and Dyeing Commissioner of Jiangning, a truly glorious position.

  The two Huai salt administration is a fat post, and those who have been able to get this position are all the emperor's confidants. Moreover, he also serves as the acting governor of Jiangning Weaving Factory. It's worth noting that his own son, Gao Heng, is still guarding the Suzhou Weaving Factory in their hometown. Gao Bin, who had just escaped from monitoring the Jiangnan officialdom, didn't know whether he was relieved or worried more. The previous round of transfers wasn't mentioned, but the identity of being the emperor's ears and eyes to monitor the Jiangnan officialdom was a thankless job that could offend people. Being able to escape from it was good, but without that layer of identity, these old foxes in the officialdom wouldn't have so many worries. As long as there were some mistakes, those who had been lenient before might come and bite him! Although the two Huai salt administration is a fat post, symbolizing the emperor's trust in himself, it also makes oneself become the flesh that others are waiting to seize...

  The more Gao Bin thought about it, the more worried he became. At a banquet, he heard a minor official from the Weaving Department say something ambiguous and suggestive after drinking. Gao Bin, who was used to thinking twice before speaking, suspected everything and immediately sent someone to summon his son as soon as he returned home.

  Gao Heng, facing his father's intense and severe questioning, naturally did not dare to conceal...

  "What?! Gao Bin felt his vision blurring, how could he have such a reckless son and daughter? Although he had tacitly agreed to let his youngest daughter serve in the palace as a maid to Emperor Qianlong, it was all part of his plan to secure the Gao family's future after the next emperor ascended to the throne, protecting them from being targeted by officials and families they had wronged in the past. Moreover, relying on his own humble contributions and his daughter's favor with the Fourth Prince, the Gao family might even be able to rise above their current status as a banner family... But now, his son was telling him that over the years, he had secretly sent so many tampered-with tribute goods into the palace using his authority as the supervisor of Suzhou's weaving and dyeing industry... This, this could be evidence that would lead to disaster if it were ever discovered, a catastrophe that would destroy their entire family!"

  To curry favor? Even the eldest brother hasn't been born yet and you're already busy laying a trap for others?! Stupid, stupid to the extreme!! "You go and deal with all those who know about this right away, did you hear me?!"

  Facing his son's fearful and puzzled gaze, he closed his eyes, gritted his teeth and said: "Now that I'm no longer the emperor's informant in Jiangnan, even though the emperor still trusts me, if someone were to expose this matter to him, our Gao family would be finished!"

  Gao Heng didn't understand the meaning behind his father's words until a while later, and he couldn't help but feel a little frightened: "Father is saying that someone wants to take revenge on our Gao family?" Is this to say that although Father has obtained a lucrative position, he can no longer dominate Jiangnan with an iron fist?

  "We, father and son, not only occupy the two Huai salt administration positions that make people jealous, but also hold the two most lucrative weaving posts in the Imperial Household Department. In the past, we had that identity to rely on, but now, well, there are those who think of taking our place. After all, as a long-time prominent figure in the imperial court, Gao Bin was shrewd and ruthless, with a hint of his master's demeanor. He glared at his nervous eldest son, "Since you've done it, regretting it now won't help. Hurry up and clean up your mess, don't let this kind of thing happen again!" The current emperor isn't as lenient as the previous one, if the matter is exposed... He thought of Nian Gengyao and Long Kodo, and his heart felt like a huge stone was weighing on it, making it hard to breathe."

  At this time, someone outside the door reported in a low voice, "Master, Second Young Mistress has brought a message from the palace."

  After all, it's his own daughter. "Bring her in!" Gao Bin made up his mind that after the salt administration stabilizes, he will properly educate his son and daughter, who is too impatient.

  He took the secret letter handed over by his subordinate, Gao Bin scanned it, paused for a moment, and then read it again from the beginning. His gloomy face slowly turned into a relaxed and joyful smile, "Heaven is indeed kind to the Gao family! Heng Er, your sister is pregnant!"

  "Dad, really?" Gao Heng rushed over and took the secret letter from Gao Bin's hand. After reading it, his face was very excited. Could their family also produce an imperial son? "But Dad, the fourth Fu Jin has another princess who is also pregnant, do you think we are..."

  "Are you saying that all of Fourth Brother's children should come from your sister's belly?! High Bin's face turned black again, this eldest son is going to take over the family business in the future, but his brain... Alas. It was indeed a correct decision to let the youngest daughter enter the palace, otherwise, whether the High family can be preserved once it falls into the hands of their sons is one thing, but they must not bring about a calamity that will lead to the death of the entire clan."

  "My son thinks that the previous method is foolproof and can be done, hasn't it been fine all these years?"

  Gao Bin sneered, "That's because for the past few years, Jiang Nan's eyes and ears have all been on me, no one dared to touch you. But times are different now, there are many people waiting to take advantage of the Gao family! Besides, under this sky, there is no foolproof method, some are just alliances of interests, knowing earlier or later makes no difference! What's more, have you forgotten what I just said?"

  "My son will go and take care of it!"

  "Wait!"

  Gao Heng turned around, and Gao Bin said: "Send the fabric to your sister again, take a look at what you're doing. Not much of it has been sent to others, but instead, you've gotten yourselves into trouble, with no place to put their mouths. Half a house full of awarded materials is piled up, but not a single piece can be used."

  Gao Heng's face turned red, if it weren't for this, he would have thought that the entire Imperial Household Department and the harem were not enough to be played with by their family.

  ……

  Another month passed and when Ping'an Mai was invited again, Yunzhu had someone notify several gege. Su Taoyi found an excuse not to be on duty, so Sun Taoyi came instead.

  Yunzhu knew in her heart that it was because of Gao Lüwei, but she didn't know that Sun Taizhen was the imperial physician who attended to the emperor. For a moment, they were both surprised and delighted, thinking it was because of the Fourth Prince's influence, and now that she was pregnant, she had become noble by virtue of her child, and couldn't help but reveal a hint of pride in her expression.

  Fu Cha. Fu Ling Ah saw the cold smile in her heart, this hasn't been born yet, and it's already so proud. Gao Shi back then crawled into Hong Li's bed under her nose, losing face for her, and later when she was pregnant with Yong Huang, she used all sorts of despicable means... thinking about Yong Huang's birth time... also couldn't escape the reason of her and Ke Lie Ye Te Shi. Thinking of these things, she can't help but hate in her heart. Fu Jun is magnanimous, but Fu Ling Ah has a grudge to settle, and her real tactics haven't been used yet.

  Don't think I didn't see the coldness in your eyes, but I'm going to pierce your eyes anyway. How will you deal with it? Are you going to give me another abortion pill?

  Gao Lu Wei rushed towards Fu Ling Ah, laughing even more happily, her eyes also glanced at Su Bao Rou who was sitting quietly on the side, reminding herself in her heart that a dog that bites does not bark.

  Dr. Sun withdrew his hand and said: "The four madams and their unborn children are all very healthy, just continue to maintain it."

  "Thank you, Doctor Sun. Please also take a look at the other princesses." Yunzhu smiled warmly, her face radiating maternal glow. Korileyte felt a pang of envy upon seeing this. Among the imperial consorts, including Ruyi, some had children, some were pregnant, but only she remained without any news. She couldn't help but rub her belly, wondering when she would also have a child.

  Sun Taizhen nodded, carefully felt the pulse of each princess, and subtly "observed" the complexion on each person's face. She also carefully distinguished between their noses, and finally prescribed medicine for each of them, some to ensure a safe pregnancy, others to nourish their bodies - this nourishment actually had detoxifying effects.

  ……

  Back at the Tai Hospital, Dr. Su was waiting there, and after exchanging a few words, they felt that it would be better to report such things to the Emperor as soon as possible.

  "Your Majesty, Imperial Physicians Sun and Su request an audience."

  "Hmm? The Yongzheng Emperor, who was revising the memorial, wrote without stopping: 'Order them to come in.'"

  "I, your humble servant, pay homage to Your Majesty. May Your Majesty live for ten thousand years and ten thousand more." The two of them entered the Palace of Heavenly Purity and performed their obeisance.

  "Rise." Yongzheng put down his brush and said in a calm tone: "What urgent matter do the two imperial physicians have to see me about?"

  Sun Taiyi and Su Taiyi exchanged a glance, but did not dare to stand up. "Your humble servant indeed has something to report to Your Majesty."

  Yongzheng glanced at Su Peisheng and immediately ordered all the palace maids and eunuchs attending in the hall to withdraw.

  "Speak." Yongzheng's voice was light and had already prepared for something that wasn't good.

  "Reporting to Your Majesty," Su Taishi began, "I went to the Western Palace a month ago to take the pulse of Empress Dowager Cixi and several princesses. I found that they seemed to have been poisoned by some unknown substance. After careful consideration, I thought that Sun Taishi's medical skills and knowledge were superior to mine, so I asked him to re-examine them during this month's peace pulse examination... In short, the two of us can now confirm that several princesses of Prince A are indeed poisoned with radix angelicae dahuricae."

  Poisoning? Or a group effort? Yongzheng sat up straight, "What is this 'monthly root grass'? Is there an antidote for this poison? Everyone get up and explain." Who was behind it? Was it aimed at Hongli or...

  "Yes." The two imperial physicians stood up, and Su Taishi replied: "This grass grows in the humid south, but is relatively rare in the north. At first glance, it looks like a wild grass, with a white line on its back, and its leaves have a pungent smell, numbing effect, and hemostatic properties. Its roots are as white as the moon, and its juice is highly toxic, capable of slowly penetrating human skin to damage one's health, corroding the body's five internal organs... I've heard that in the past, indigenous people from Yunnan's Lingnan region used this grass to make poisonous arrows; I don't know if they still use it now."

  Su Taizhen briefly introduced the grass and said: "People who have been poisoned by this toxin will not show any signs on the surface, but their body will gradually weaken. Only after the poisoning has deepened can one infer from the color of the pupils and the subsequent weak pulse. Those who are deeply poisoned will have skin that becomes even whiter and emits a very faint, mysterious fragrance. I deduce that Fucha Gege was poisoned by the Month Root Grass toxin perhaps three or four years ago."

  Isn't this murder without seeing blood? Yongzheng remembered that Wu Lala's hands seemed to have similar medicine in the past, which also eroded the vitality of the human body. Fu Hui was lucky to meet Yunzhu, otherwise she would have ended up like Hongyi and Hongjun. He thought that such things would disappear with the death of the empress, but they appeared again... Thinking of this, his eyes narrowed slightly, "According to what you said, only four concubines in Qianxi's mansion and Gao Gege did not take the poisonous moon grass?"

  "Yes." The two imperial physicians replied in unison.

  "Can it be that so many people have been poisoned without anyone noticing, and yet no one suspects anything? It's clear that nothing has been done to the food. Do either of you two imperial physicians have any ideas?" Could it be Yunzhu? No, she doesn't seem like the kind of person who would do such a thing... But a woman's mind is hard to understand; after all, hadn't he also never suspected that the virtuous empress would harm his children?

  Su Taizhen hesitated for a moment, saying: "I heard that there is a secret method, which involves obtaining the root juice of the Moon Root Grass and then soaking it into the fabric and embroidery threads. Wearing clothes made from this fabric and thread for many years can also secretly drain away a person's vital energy..." This method was still recorded in that medical book he had obtained, and when he first read it, he wondered if the author of the book was also an imperial physician in the palace, or else how would they know about such tactics used in harem struggles.

  Yongzheng listened and didn't know what he thought of, his face slowly turned cold, after a while, he said to Su Peisheng: "Think of a way to inform Ye Nainai to come to Yangxin Hall tonight. Also, order someone to pay attention, as soon as the Fourth Prince returns to the palace, let him come here, don't disturb others."

  "Hmm." Su Peisheng listened from start to finish and knew that the Emperor was worried that the Fourth Prince had also been poisoned, so he didn't dare to be careless and hastily responded and left.

  The author has something to say: The following is the main body of the text:

  And without mentioning how Su Taishan discovered the shocking secret in Qianxi, he was restless for two days and finally found Sun Taishan, the chief physician of the Imperial Hospital, and secretly told him about it.

  "If this matter is exposed... I'm afraid the entire imperial palace will be turned upside down, and the consequences will not be small.

But hiding and not reporting is also a crime of deceiving the emperor... Therefore, I have no choice but to come and ask for Brother Sun's help with a thick face."

  "Two years ago, my grandson found an old book in the study that described many rare flowers and herbs, as well as some strange stones that could cure or cause diseases... I was skeptical at first, as most of what was written were things that I, a doctor with decades of experience, had never heard of or seen.

Being able to escape from it was good, but without that layer of identity, these old foxes in the officialdom wouldn't have so many worries.

Although the two Huai salt administration is a fat post, symbolizing the emperor's trust in himself, it also makes oneself the flesh that others are waiting to seize...

  The more Gao Bin thought about it, the more worried he became. At a banquet, he heard a small official from the Weaving Department say something ambiguous and suggestive after drinking.

  "Wait!"

  Gao Heng turned around, and Gao Bin said: "Send more fabrics to your sister again, take a look at what you're doing, not many things have been sent to others, but instead, you've gotten yourself into trouble, with a whole room full of gifted materials that can't be used at all." Faced with the request at the end of the secret letter, Gao Bin guessed the true situation without even thinking.

  Gao Heng's face turned red, if it weren't for this, he would have thought that the entire Imperial Household Department and the harem were not enough to be played with by their family.

Her expression couldn't help but reveal a hint of pride.

  Fu Cha. Fulinga saw the cold smile in her heart, and she hadn't even given birth yet, but was already so proud of herself. Gao Shi had crawled into Hong Li's bed under her nose back then, losing face for her, and later when she was pregnant with Yong Huang, she used all sorts of despicable means... thinking about the time of Yong Huang's birth... it was also inseparable from her and Ke'er Yuet's reason. Thinking of these things, she couldn't help but hate in her heart. Fu Jun was magnanimous, but Fulinga had to repay her debts, and her true methods hadn't been used yet.

  Don't think I didn't see the coldness in your eyes, but I'm going to pierce your eyes anyway. How will you deal with it? Are you going to give me another abortion pill?

  Gao Lu Wei rushed towards Fuling Ah, laughing even more happily, her eyes still didn't forget to glance at Su Bao Rou who was sitting quietly on the side, reminding herself in her heart that a dog that bites doesn't bark.
