Originally, Yue Xiyuan planned to meet Yan Shaoheng today and take some of his hair for Yan An to do a paternity test.

Unexpectedly, a letter arrived from the Dark Pavilion, leaving them no choice but to have Dark Four deliver the prepared fish.

One reason was to tell Yan Shaoheng that he had begun investigating what happened 28 years ago.

Secondly, I really wanted Yan Shaoheng to taste the fish from the moat again.

"Did you get the chopsticks too?"

"Reporting to Your Highness, it has been sent to the Princess Consort, but Bai Tao said that the Princess Consort went back to rest."

"Okay, go down."

I must be exhausted from the past two days, especially after such a long surgery.

"Dark Four".

An Si, who had just left, was called back before he could even close the door properly.

"Go to the palace and take some of the sea cucumbers that the Lu Kingdom sent a few days ago to An'an."

An Si glanced at the sky outside. The city gates were already closed. His master wanted him to go to the palace to get sea cucumbers?

[Sigh, so be it. For the sake of my lord's love, for the sake of the hard-won mistress of the manor, what does a life of toil matter!]

This is love!

"I'll go right away."

Yue Xiyuan took out the letter sent by the Dark Pavilion, which read: "The Grand Preceptor of Yan Kingdom has refined an elixir of immortality that can reverse aging. The Emperor and Empress Dowager of Yan have both taken it."

"An Yi, when did this happen?"

"Your Highness, the matter of the Imperial Preceptor was announced by the Emperor of Yan during the morning court session this morning. At the same time, to show his loyalty, the Imperial Preceptor offered up a pill he had been developing for a long time, called the Elixir of Immortality."

Why was there no news before?

"Please forgive me, Your Highness, I was unaware of this."

"Have you ever seen the face of the Imperial Preceptor?"

"Your Highness, that person was wearing a silver mask the whole time. In my opinion, he should be quite young."

Why?

"The Emperor of Yan was overjoyed upon receiving the elixir of immortality and bestowed upon the Imperial Preceptor a fine residence, located directly opposite the Linglong Pavilion. I glimpsed him through the window; his face was as white as snow, and he possessed a certain... a certain..."

"What kind of thing?"

"It has a seductive and alluring quality."

An Yi didn't know what word to use to describe him, but at this moment he felt that 'alluring and seductive' was exceptionally appropriate.

Yue Xiyuan remembered that Su Jingzhan had once told him:

"The people behind the immortals are all experimenting on living people. This heinous behavior reminds me of someone, Yun Xi."

"He is my master's junior brother, also a disciple of Tianxuan Daoist. He is skilled in martial arts and poisons, especially poisons, which he is incredibly proficient in. My master said that no one except our grandmaster can cure his poisons."

"At that time, his master was worried that he was too obsessed with poison and that he would go astray. He tried to dissuade him many times. Yunxi agreed on the surface, but never acted according to his master's words."

"Later, Yunxi was not content with remaining hidden from the world, so he secretly went down the mountain and found many lonely old people to refine medicine."

"Later, as time went on, he realized that the elderly were already physically weak and wouldn't last long after taking his poison, so he turned his attention to some young and strong people."

"Because the grandmaster couldn't find Yunxi on the mountain for a long time, he calculated that Yunxi had caused such a big trouble. It was too late, so he sent his uncle and master down the mountain to capture Yunxi."

"Master and the others naturally knew that what Yunxi had done was unforgivable, but since they were from the same school, they couldn't bear to do it and persuaded him to hand over the antidote so that their grandmaster could spare his life."

"Later, perhaps he was really scared, so he handed over the antidote. With his master and the others pleading for him, and his grandmaster's reluctance, he crippled all his cultivation, making him like a cripple, before letting him go down the mountain."

"Before leaving, Yunxi left a note for his master and the other two, saying that it was a great blessing that those people could be his test subjects, and that even if there was an antidote, it would be difficult to bring them back to life."

"Later, after three days and nights of painstaking research, the master finally developed the antidote and saved the people who had been tested on by Yunxi for many years."

“From then on, my master often regretted it, wondering whether it was right or wrong to plead for him.”

"Fortunately, when Yunxi came down the mountain, he was already like a cripple. The foundation of his hands had been severed, and he could no longer refine poisons."

When Yue Xiyuan recalled the story of Yun Xi that Su Jingzhan had told him that day, he felt that it was remarkably similar to the person behind the immortals.

But if Yun Xi were still alive, he would be over sixty years old now. Not to mention his gray hair, his demeanor and appearance would certainly not be like mine.

In Yue Xiyuan's mind, Yun Xi, the person behind the immortals, and the Yan State's Grand Preceptor were all questioned.

"Has the Emperor of Yan consumed an elixir of immortality?"

"During the morning court session, the Emperor and Empress Dowager personally fed one to the nanny by the Empress Dowager's side. In less than half an incense stick's time, the nanny had already changed her appearance. Some people said that the nanny's appearance was even better than when she was young."

"Everyone in the court except the Grand Preceptor was shocked, but the Emperor and Empress Dowager of Yan were also very cautious and did not eat it immediately. They simply kept a close watch on the nanny."

According to An Yi, this elixir of immortality does indeed have the effect of reversing aging. Since she dared to let people test the medicine in public, this old woman probably won't show any symptoms in the short term.

"Keep an eye on that Grand Preceptor. If you find out that either the Emperor of Yan or the Empress Dowager has taken the elixir of immortality, report it to me immediately."

"It is Your Highness."

Yue Xiyuan's current thorough understanding of the situation in Yan State demonstrates the immense effort he has put in over the years.

Linglong Pavilion has been established for so many years. In addition to being a mask for the Dark Pavilion, it also has a special place in the other three kingdoms. It does not use silver, but only one thing.

That is "information selling," located in the deepest part of Linglong Pavilion, which those who have been there call "secret."

There are too many things in the world that are priceless and invaluable. Therefore, for those things that cannot be purchased with silver, or things that Linglong Pavilion stipulates are not for sale.

Those who want something should show the utmost sincerity and exchange the most reliable and useful information for what they want.

This thing can be an object, or it can be a message.

Because, for the four kingdoms, the owner behind Linglong Pavilion is not from any of them, and has no political stance whatsoever. For Linglong Pavilion, money and information are the most useful things.

Linglong Pavilion will conduct an "appraisal" based on the information provided by the seller, and the "price" will be fair.

If you don't get what you want in exchange, or if you don't have enough information to exchange for it, you can exchange for other things or exchange for silver.

But once you step through the door of 'secret', there is no turning back.

Although the risks were great, the potential rewards were too good to pass up, so some people were still determined to give it a try. Over time, people discovered Linglong Pavilion's sincerity.

Linglong Pavilion never questions the identity of those who sell information; once the information is sold, it belongs solely to Linglong Pavilion.

This is also the secret behind Linglong Pavilion's thorough understanding of other royal families.
