Fu Yao saw Tang Siru's expression change, and his expression became solemn, "Is there a problem with this one?" ”

Tang Siru took a step back, nodded and said, "The ink in this envelope is different shades, and there is not only a precious musk smell in the taste, but also a strange pungent smell. ”

"Pungent smell?" When Fu Yao heard this, he took the letter and examined it carefully.

Suddenly, a cold look appeared on his face, "It's silver cinnabar." ”

"What is silver cinnabar?" Tang Siru was confused, she could only know what the problem was, but she didn't know what it was mixed with, she couldn't help but be a little curious, "It sounds like cinnabar......"

Fu Yao explained: "Cinnabar, also known as cinnabar, in addition to the painters who like to use it as pigments, many Taoist alchemists love to use it to refine elixir. ”

Speaking of which, Tang Siru somewhat understood, many emperors in ancient times pursued the way of immortality and asked warlocks to refine their pills, but the pills contained mercury, and it was because of the attitude of taking such mercury-containing pills that many emperors ascended to the Elysium early and gave way to their sons.

In other words, cinnabar is used to practice mercury.

"Silver cinnabar is cinnabar with mercury." Fu Yao explained.

Tang Siru suddenly realized that mercury is mercury, which is often touched, and accompanied by some daily actions, if you accidentally eat it in your stomach, you will naturally be poisoned.

It seems that there is no such thing as a fantasy poisonous gas, otherwise the smell will evaporate over time, and it will inevitably poison the people who come into contact with it.

"That is to say, there is mercury in the ink, Your Majesty often looks at the folds, it is inevitable to touch it with your hands, once it is stained on your hands, and then you drink tea and eat, it will inevitably be eaten into the stomach, so that although it is a trace every time, but in the long run, it will also form a big trouble." Tang Siru understood the principle of poisoning.

"Miss Tang Er is really smart." Fu Yao smiled slightly and praised.

"Let's see who handed this notebook, this person is the one who poisoned it!" Tang Siru looked through the cover of the book.

The book was a blue cover, and according to the practice of this dynasty, it was an excerpt sent by the courtiers to report on weekday affairs.

Fu Yao shook his head and said: "Don't look at it, most of this kind of blue seal is handed over by the ministers every day, and after handing it over, someone will copy it aside, and it is not the original at all." ”

Tang Siru was surprised: "That is, the person who copied used poisonous ink?" She clenched her hands into fists and slapped her palms, "This kind of random selection of one is used for poisoning, even if you find out which one is poisonous, you can't catch who poisoned it, it's really hateful!" ”

The dark clouds spread between Fu Yao's eyebrows, "It's good that the murderer is poisoned, so it's better to take precautions as soon as possible." ”

Tang Siru was shocked, "Don't you want to find out who the murderer is?" ”

Fu Yao whispered: "Your Majesty has discussed with me, and I have already planned at this time, so Your Majesty can also take this opportunity to recuperate and see the turmoil in the imperial court." ”

Tang Siru looked at Fu Yao, only to feel that he looked like a fox at this time, and even his slightly curved eyes were full of routines.

Here, Fu Yao and Tang Siru have already found out the clues, but they have not moved, and the sect king faction over there is not calm.

King Zong's real name is Liu Zong, born to Concubine Xian, crowned King Zong, fief in Jinling, very close to the capital.

There is already a crown prince in the court, and the king of the sect naturally wants to stay in the fiefdom, and he is not allowed to enter Beijing without major events.

At this time, King Zong was teasing a parrot in the courtyard of the palace, the parrot was bright in color, smooth and slippery, and it looked like a finely fed bird.

King Zong looked only twenty-five or sixteen years old, with a white face and sparse eyebrows, and he was born with a cowardly appearance. He was wearing a loose robe made of silk linen and white silk to feed fruit to his parrot "Basho".

Sitting opposite him was a middle-aged man in a blue coat, who was bowing his head and blowing a cup of tea in front of him.

"Master Yu, do you think my cup of Huoshan yellow buds can suit your taste?" King Zong asked with a smile on his face.

"What's wrong with the things here Your Highness, Yu Mou is blessed." Yu Chengshu said with a smile.

"What's the matter, Lord Yu works for the queen's mother, and it's rare for me to be a rough thing in the countryside?" King Zong said unintentionally.

"Alas, what does Your Highness say, eat the king's lu, share the king's worries. Yu has always served His Majesty and is His Majesty's courtier. Yu Chengshu's face did not change his color.

King Zong didn't refute either, and continued, "I heard that the queen mother has been quite anxious recently? ”

Yu Chengshu smiled bitterly, "The queen's mother's family is in decline, how can the queen not be busy for a while." ”

King Zong said: "Why, the Ministry of Industry Shangshu Fan really can't help it?" ”

Yu Chengshu lowered his eyebrows and said: "The matter of the Lizhou Canal, Prime Minister Fu Yao of the left side thoroughly investigated the case, and His Majesty personally ordered that unless the crown prince ascends the throne now, this Fan should be considered over." ”

"Oh?" King Zong raised his eyebrows, "Fu Yaocha, that's over." ”

"Therefore, the queen mother is very unwelcome to Lord Zuo Xiang now." Yu Chengshu said.

"This Fu Yao is also a saint, and the queen can't help it. You said that this Lord Fu, but the red man in front of His Majesty, this time His Majesty was seriously ill, and he directly ordered him to supervise the country, without mentioning the prince. "King Zong said.

"Yes, you said that Your Majesty is even guarding against his own son, but he trusts this Fu Yao." Yu Chengshu also said.

King Zong joked, "It's not surprising, when I was in the palace, His Majesty took pity on the death of his parents, and he was quite fond of him. There is also a rumor that His Majesty was in love with Fu Yao's mother Bai Tang when he was young, and we all thought that Fu Yao was the illegitimate son of his father. ”

"I can't get used to Fu Yao, he is young and powerful, and he is favored by the saints, so he teaches people to be jealous." Yu Chengshu said bluntly, "But if Fu Yao is the illegitimate son of His Majesty's young and cheating affair, it makes sense to be so favored." ”

After saying that, King Zong and Yu Chengyao glanced at each other, and they both smiled meaningfully.

Fenglai Palace.

The maid's hand trembled slightly, and she smeared Queen Fan's Kodan out of bounds, and then knelt down in horror, "The slave is guilty." ”

The queen waved her hand in disgust, "I can't do this little thing, let's go down quickly." She looked at the kneeling right minister below, "Get up and speak." ”

After Yu Chengshu sat down, the queen said again, "Let you go and see if there is any opportunity to transfer Fan Dang, now you have eyebrows." ”

Yu Chengshu smiled bitterly, "Niangniang, Weichen has done his best, and now Zuo Prime Minister Fu Yao is in charge of the country, and Fan Dang is personally investigated and dealt with by him, it is really difficult to do." ”

He changed his words, "Alas, you said that if the crown prince is in charge of the country, isn't this matter a matter of course?" It's this Fu Yao! I don't know why His Majesty spoiled him so much, and it makes sense to say that he is his own son. ”

After finishing speaking, he covered his mouth with a look of horror, "Niangniang, Weichen was talking nonsense just now, don't be surprised." ”

The queen's gaze was far-reaching, and she said leisurely: "Don't say it, with Your Majesty's trust in him, Fu Yao may really be Your Majesty's illegitimate son......"
