Zhao Na, Grand Master of Daduan Dynasty, is in his forties. He is tall and thin, with a hooked nose, pointed chin, and eyes as bright as an eagle. His mouth is often pursed tightly. When thinking about things, his index finger and thumb will move. Twist and twist consciously.

He was a well-known expert at internal struggles but a novice at external struggles. He had never gone out to fight in the battlefields to achieve great achievements, nor had he ever contributed any strategies to stabilize the country. He was only good at infiltrating official circles and getting along with everyone, and he was also quite knowledgeable about the art of palace struggles in the harem.

"Master, Master, what do you think we should do next?" Tai Shi's wife Shan Lan was both happy and worried: "Sister, no, Concubine Shan said that the Queen and Master Yun exchanged letters, and the evidence is solid. Can we overthrow the Queen with just this letter?"

"It's hard to say." Master Zhao was silent for a while: "Although I am about 70% sure, it's still not enough."

"Oh, it's really chicken ribs. It's not right to let people chew it, and it's not right not to chew it!" Shan Lan sighed.

"However, the moon-viewing and lantern-watching banquet tomorrow night is a good opportunity!" Grand Tutor Zhao looked sharp at the sky outside through the window paper.

"A banquet to watch the moon and lanterns?" Shan Lan was puzzled: "Master, didn't I tell you? The Queen and the Crown Prince will not be there. Only my sister and the other concubines will be there!"

"That's why I said this is a good opportunity." Tai Shi Zhao said, "As far as I know, His Majesty the Emperor will host a banquet to entertain the Persian envoys that night. He will neither attend the moon-watching and lantern-viewing banquet nor go to the Empress' Yuanheng Palace."

"So what?"

"In Yuanheng Palace, only the Queen and Master Yun were alone. Although the Crown Prince was there, he was still bedridden." Grand Tutor Zhao clapped his hands and laughed, "How can there be such a good opportunity again?"

"That's right!" Shan Lan suddenly realized: "The concubines are all enjoying the moon and lanterns, and they won't go to disturb them, so the Queen and Master Yun can do what they want!"

"As long as we send a reliable person to Yuanheng Palace to investigate, we can find something to hold against the Empress. Combined with the letter, we can bring her down in one fell swoop!" Grand Tutor Zhao looked vicious.

"But...but...what if the empress and Master Yun are innocent and have nothing to do with each other?" Shan Lan said worriedly again: "In this case, even if we send someone, we won't be able to find any evidence."

"It's not up to them to decide whether someone is innocent or not."

"But that musician has a quirk. He gets so scared he faints when he sees a woman!"

"He is smart. He wants to avoid suspicion this way." Taishi Zhao sneered, "But if we were to say it, it would mean that he and the queen had something going on. He deliberately pretended to be like this to avoid being noticed!"

"That's right!" Shan Lan clapped her hands: "People are two-faced, and whatever they say is right!"

"As long as we produce solid evidence of their crimes, they won't be able to explain themselves even if they have a hundred mouths." Master Zhao sneered, opened the lock on the bedside, and took out a piece of red paper with his skinny hands.

Yuanheng Palace.

"Report, the Empress said that there will be a moon-watching and lantern-viewing banquet in the harem garden tomorrow night. The Empress, the Crown Prince, and Master Yun do not need to attend. Just rest here." The young eunuch Ding Xian delivered the Empress' order.

Li Yuebai's expression became serious.

The moon-watching and lantern-viewing banquet is a very exciting and cruel chapter in the original work.

In the original novel, on the night of the moon-watching and lantern-viewing banquet, His Royal Highness the Crown Prince still fell asleep in bed from time to time, and Yun Weizhi and the Empress were by his side. Unexpectedly, at the second watch, Concubine Shan left the banquet alone and came to Yuanheng Palace.

Concubine Shan paid her respects to the Empress, talked about some family matters, and then asked the Empress to send away the palace maids and eunuchs. Then, she secretly took out a piece of paper.

The paper was red, but the writing on it was yellowish-white, as if mixed with gold powder. The lines of text were very delicate and beautiful, but it was impossible to tell which country's language they were from.

Concubine Shan said, "This is a fragment of a poem left by the poet Wu Zidao of the previous dynasty. It was copied by a folk poet and I just happened to get it today. I thought Your Majesty would love to enjoy it, so I specially came to present it to Your Majesty."

The poet Wu Zidao of the previous dynasty was famous for his profound knowledge and mastery of the writing systems of various countries in ancient and modern times, leaving behind many fragments of his poems. The empress loved poetry and whenever she got a good poem, she would copy it down by hand. She immediately ordered her maid to take it and examine it carefully under the bright moonlight. It was indeed a wonderful thing she had never seen before.

When Concubine Shan saw that the Empress liked her, she was quite proud. She drank a few cups of tea and then hurriedly said goodbye.

Unexpectedly, after returning home that night, Concubine Shan fell ill in bed and was unconscious. She asked the imperial physician to diagnose her, and the doctor said that she had been poisoned.

That night, Concubine Shan attended a banquet to watch the moon and lanterns. None of the other concubines were poisoned, so why was she the only one poisoned? After tracing the cause, it was discovered that on the night of the banquet, Concubine Shan went to the Empress's Yuanheng Palace and drank a few cups of tea there.

The emperor was suspicious by nature and had always favored Concubine Shan and distanced himself from the empress. When he heard about this, he was furious and ordered a thorough investigation. After interrogation, they all said that when Concubine Shan met the empress, the eunuchs and maids were dismissed. Therefore, no one knew what had happened.

The emperor ordered a thorough search of the empress's Yuanheng Palace, and found several pages of poetry written in black and white. The words were harsh and strange, and no one could recognize them, but they were indeed the empress's handwriting.

The scholar from Longyuan Pavilion came to identify the handwriting and recognized it as the language of Yue. When he saw the content, he broke out in a cold sweat and his hands were shaking.

This is a love poem!

It is not only a love poem, but also written from a woman's perspective to her lover. The name of the poem is translated into Chinese as "Ten Fragrance Poems".

Not only that, the lover's name is often mentioned in the poem, which is exactly the word "云" in the Yue language!

Moreover, this was the Queen's handwriting, and it was found in the Queen's palace, and Master Yun happened to live in the Queen's palace...

No matter from which angle one speculates, this must be a love poem written by the Queen to Master Yun.

The queen was shocked and quickly explained, "It is true that I wrote this, but I do not know the Yue language. I just copied it down! On the night of the moon-watching and lantern-viewing banquet, Concubine Shan came to my palace and brought me a page of an out-of-print poem on red paper. I copied it down!"

The emperor's face turned pale, his eyes almost popped out of their sockets, and he shouted, "Empress! You keep saying that this is a copy of the red paper poem sent by Concubine Shan, but what evidence do you have? Where is that page of red paper poem now?"

The queen calmed herself down and finally felt relieved. Yes, she had always loved poetry very much, and the red paper she had left last night was naturally kept carefully by the bed. So, she went to look for it herself, but only found a trace of paper ash.

The queen could only explain: "I clearly put it here last night, but now..."

"Does the Queen want to just use a bit of paper ash to appease me?" The emperor became more and more angry.

After being examined by the imperial physician, the poison that Concubine Shan was poisoned with was discovered, which was "Baiwang Powder".

Baiwangsan, as its name suggests, will make you dizzy, confused and forget what happened that day if you mix it with tea and drink it.

Therefore, Concubine Shan had completely forgotten about her visit to the Empress's palace that night. No matter how the Empress questioned her, she insisted that she had no recollection of giving the red paper poem to the Empress.

"Although Concubine Shan has forgotten, my maids and eunuchs can testify to it!" the Queen argued.

"They are all your people, so they will naturally cover up for you!" The emperor said angrily, "And someone has already said that you were in the same room with Master Yun on the night of the incident, and were caught by Concubine Shan! Later, you dismissed your attendants and talked to Concubine Shan alone!"

After the imperial physician's full efforts to treat her, Concubine Shan's poisoning symptoms gradually improved. Although she still could not recall what happened that night, she could still recall some fragments. Concubine Shan lay on the sickbed, her voice weak, "I only remember that the Empress and Music Master Yun had a very pleasant conversation, but I don't know what happened next."

In this way, things became clear in the eyes of the emperor and everyone else.

On the night of the Moon Viewing and Lanterns Banquet, the emperor was busy entertaining envoys from foreign countries, and all the concubines were feasting in the garden. In Yuanheng Palace, the queen took the opportunity to have an affair with Yun Leshi and even wrote an erotic poem.

Unexpectedly, Concubine Shan suddenly went to Yuanheng Palace to pay her respects to the Empress and accidentally discovered the secret.

So the empress dismissed all the maids and eunuchs, comforted Concubine Shan, and gave her tea mixed with "Baiwangsan" to make her forget that she had witnessed the affair.

Unexpectedly, Concubine Shan was too weak and had a severe reaction after taking the medicine, so the truth was exposed.

The evidence was clear, and the Queen was speechless.

The only excuse she could offer was that she did not know the Yue language at all, and neither did Yun Yueshi, so it was impossible for the poems written in Yue language to echo each other. However, no one believed her.

Everyone knows that the empress is extremely talented and can compose poetry and compose verses, and that Master Yun is like a banished immortal. With their talents, it is natural for them to know the Yue language.

An unjust case was thus created.

The whole plan of Zhao Ne and the Shan sisters is impeccable and well-connected. However, it is by no means impossible to crack. In fact, it is easy to crack as long as you can counter each move.

Li Yuebai curled up in the quilt, biting his fingers and thinking hard.

"Your Highness." Finally, he called out to the naughty child on the bed who kept looking at him, as if he couldn't get enough of looking at him: "I have a lot of words to advise the Empress, please help convey them to her, Your Highness."
