Yun Ruo Lu returned the silk handkerchief to the aunt and continued to ask: "Aunt, do you know where that young lady came from? What does he look like? When did you get here? "

The aunt knew that she was a bodyguard who had accompanied the Third Marquis. She thought that it might be helpful in solving the case, so she continued, "It should have been about five days ago. I heard that the young lady is a renowned courtesan from a brothel, which is very popular with the eldest young master. It's just that the girl was wearing a veil at the time, so I don't know what she looked like. "

A lady from a brothel? Five days ago?

Yun Ruo Lu suddenly felt that some important clue was appearing on the surface, so she excitedly asked: "Then do you know which brothel's renowned courtesan she is from? "What's your name?"

Shangguan Yuan had been to the construction site with this brothel lady before the accident, it was an unusual occurrence.

Plus, Shangguan Yuan mentioned this place when he was drunk, there must be something here that made people drool.

That auntie thought for a while, then shook her head and said, "I really can't help with that. How would we, the servants, dare to ask about the matter of Eldest Young Master?"

Although she didn't get all the information, Yun Ruo Lu felt that she knew enough to continue checking.

Thus, Yun Ruo Lu ran to Yuchi Xuan's side and told him what she knew.

Hearing this, Yuchi Xuan's expression changed and he said to Huai An at random, "Let's go back first! There are more important things waiting for us! "

Thus, the three of them galloped back to the city.

On the way back, Yuchi Xuanyuan left the investigation of the brothel woman to Huai An. He was asked to investigate which brothels Shangguan Yuan had visited in the past half month, and which girls he had stayed with.

This way, they would be able to find the brothel girl through layers of elimination.

Even if that woman had nothing to do with the annihilation of his clan, with Shangguan Yuan's favor for her, he was sure she knew some things.

Back in the city, everyone began to busy themselves.

Yuchi Xuan was in charge of the mine, Huai An was in charge of investigating the brothel women, and Yun Ruo Lu was in charge of understanding the families of the three families that had been annihilated.

Because they were killed by people from the same organization, and that mysterious organization took what they wanted from every family.

As long as they could find out the backgrounds of these families, they would be able to figure out who the organization's next target was.

Yun Ruo Lu spent the night and night flipping through the books regarding the three families, while Yuchi Xuan ran around the city and the mines every day. Huai An had been walking through the streets and alleys, inquiring about the various families.

After the three of them had worked together, on the third night, they finally found the clue they were looking for.

The night of early autumn was rather cold, and the courtyard of a certain manor seemed deserted. The cold wind recklessly blew against the candles in the corridor, causing the quiet night to seem particularly desolate.

Yuchi Xuan, Yun Ruo Lu, and Huai An were secretly conversing in the room. In order to prevent outsiders from eavesdropping, Yuchi Xuan had all of the guards hide themselves, creating a desolate scene in the courtyard.

"I have already found out. That day when Shangguan Yan left the mine, the woman's name was Ru Yan. She was a renowned courtesan from the Fragrant Sky Tower, and the time it took for her to fall was less than a month. From the first time Shangguan Yuan had gone to the Fragrant Sky Tower, he had taken a fancy to this woman called Ruyan. However, on the second day of the Yun Family's annihilation, Ruyan had been sold off by a mysterious client. "So right now, there's no one left in Fragrant Sky Tower."

Huai An began by narrating the results of his investigations over the past two days. Both Yuchi Xuanyuan and Yun Ruo heard this and felt that it was too much of a coincidence. Perhaps that Ruyan had long since been planted in the Fragrant Sky Tower and was close to Shangguan Yuan.

"Yunyou, what about you? What did you find there? "

Yuchi Xuan looked at Yun Ruo You and asked. The things that Yun Ruo Lu had known these past two days were things she had never thought of before. Furthermore, it was extremely complicated.

"Your Highness, I think it's better if you tell me first. I won't be able to say it clearly for now."

She had a feeling that if there weren't any problems, then with the way they had been investigating this matter these past two days, the murderer would definitely be lured out tonight.

Yuchi Xuan gathered his thoughts, then said, "I've only found one thing. It's not very special, but it's very important."

"What is it?"

Huai An and Yun Ruo Lu looked nervously at Yuchi Xuan, waiting for his next words.

"Five days ago, Shangguan Yuan received a notice from his subordinate saying that a locked iron box had been excavated from the mine. After that, Shangguan Yuan brought the woman called Ruyan along to the mine.

"If that's the case, then it's very possible that Ruyan came for that metal box, and the Shangguan Family's extermination case is also related to this metal box!"

Huai An conjectured based on Yuchi Xuan's words. Both Yuchi Xuan and Yun Ruo Lu nodded in agreement.

"Then where is the iron box now?"

Yun Ruo Lu asked in confusion, thinking that they had already taken it away.

Yuchi Xuan shook his head, indicating that he did not know anything. He sighed and said, "I've already ordered people to search through the destroyed Shangguan family, but I didn't find that metal box."

Yun Ruo rolled her eyes as she thought about it. She then said, "Maybe I know where the box is! But the condition is that we must find the letter Shangguan Yuan mentioned! "

"You mean the iron box might be with the owner of the letter?"

Yuchi Xuan reacted quickly. Yunluo nodded and continued, "I already know about the relationship between the Shangguan family, the Jin family, and the outer sect of Chen."

Hearing this, Yuchi Xuan and Huai An looked at Yun Ruo Lu in disbelief, asking in unison, "What relationship?"

Yun Ruo Lu took a piece of white paper from the desk at the side, and drew on the paper with her brush as she said, "Shangguan Rongyi, Jin Haicang, and Chen Sheng were all imperial guards of the previous dynasty. They served the previous emperor's empress, and because of some unknown matters, they left the palace and went back to their hometown as ordinary citizens."

"The personal guard of the previous empress? Aren't there five people? "

Yuchi Xuan naturally knew quite well about the affairs of the palace. Thus, upon hearing Yunruo's words, Yuchi Xuan was able to guess what was going on.

"Yes!" Therefore, the remaining two people are their next target! "

As Yun Ruo said resolutely, Yuchi Xuan's expression became increasingly grim. In fact, there was a trace of killing intent in his eyes.

"Then what is this unknown matter?"

Huai An asked in confusion, but the moment he said those words, he immediately felt regret, because he had asked something that he shouldn't have.

Although Yun Ruo Man didn't know what was going on, she could guess that this matter was definitely related to the dignity of the imperial family.

"Huai An, go back first. I have matters to discuss with Yunyou alone!"

Yuchi Xuan purposely moved away from Huai An and waited until there was only Yun Ruo Lu and the two of them in the room before he asked with a dark tone, "There are only two of you now. What else did you find out?"

Almost no one in the Imperial Palace knew of that secret back then, and if it were to be spread out, the world would certainly fall into chaos. His birth mother had died because of injustice!

Yun Ruo Lu had never seen such a terrifying expression on Yuchi Xuan's face. It was as though he could kill her at any time without any mercy.

"What does Your Highness want to know? Could it be that the Prince thinks that Yunyou is capable of investigating the secrets of the Imperial Family with just two days of investigation? "

Yun Ruo's rhetorical question was effective. Yuchi Xuan thought about it for a while and felt that it was impossible. Thus, he relaxed his expression and said, "It's fine. You should go back and rest!"

"Your Highness, if there's anything you need, Yunyou will definitely help Your Highness!"

She could tell that Yuchi Xuan was hiding a secret, and that the secret involved the entire Yuchi Dynasty.

After Yun Ruo Lu left, Yuchi Xuan calmed himself down. He casually glanced at what Yun Ruo Man had just drawn on the paper and his eyes immediately lit up.

He already knew where he was going to find the remaining two people from the imperial guards!

The case of the Shangguan Family being exterminated was secondary, capturing the culprit of that organization was the most important. Therefore, Yuchi Xuan planned to let go of the Shangguan family case and directly capture the members of this organization!

The next afternoon, Yun Ruo Lu came to the Fragrant Sky Tower alone.

Last night, Huai An was not very clear, so she wanted to personally come and see, maybe she could find out more about that Ru Yan.

Although most brothels only opened at night, the Fragrant Sky Tower was one of the most famous buildings in the Flower Capital, so even though it was still noon, the place was already packed with people.

Of course, most of the guests only came here for fun, so the moment Yun Ruo Lu entered the Fragrant Sky Tower, she saw some indecent images.

At the side of the stone pillar at the entrance, a fat middle-aged man was hugging a girl who was dressed beautifully to the point of hugging her tightly while reaching out his hand to touch her body in an unbridled manner.

Only then did Yun Ruo understand that brothels were brothels, there was no such thing as an elegant place.

These men were like hungry wolves when they came here. They all had lustful eyes and vulgar smiles.

When Yun Ruo Lu heard that Fragrant Sky Tower was one of the best buildings in the world, she thought it would be an elegant place with a few ladies singing and dancing on the stage. If she had known this would happen, she definitely wouldn't have come alone!

"This is the first time this guest has come to our Fragrant Sky Tower. Would you like me to introduce you to some pretty girls?" Tao Zhu, Xing'er, Little Mei, come and receive your guest! "

The moment Yun Ruo You entered the Fragrant Sky Tower, she couldn't even stand still before the shrewd voice of the old procuress rang in her ears. Following which, several young ladies whose names were called surrounded her.
