When Xiao Yunrou learned that Wanqing had become a concubine of Duke Yue, she was a little surprised. Although she asked Wanqing not to appear in the brothel, she didn't expect that Duke Yue would take her back directly. However, Wanqing was a decent girl, and no one would say anything if she was taken in. But Xiao Yunrou knew that the wife of Duke Yue was not so good-tempered, and Wanqing was young and beautiful, so the backyard would definitely be in turmoil.

As expected, Duke Yue suffered a series of defeats in the court. Lady Yue was neglected because of Mu Yuying, and now a little girl appeared out of nowhere. Lady Yue even thought that if her son was not the prince, would she have completely lost her power in the Duke's Mansion?

For this reason, the wife of the Duke of Yue fought with Wanqing every day, but Wanqing was no match for the carefully cultivated wife of the Duke of Yue, and could only suffer constant grievances. The Duke of Yue originally liked Wanqing, especially her innocence. Compared with the increasingly arrogant wife of the Duke of Yue, he loved and sympathized with Wanqing more. However, he could not openly punish the wife of the Duke of Yue because of Wanqing. The crime of favoring a concubine and destroying a wife is not something that the Duke's Mansion can afford. In response to this situation, one is face, and the other is the woman he likes. The Duke of Yue opened up many privileges in the mansion to Wanqing, and even equipped her with two guards to protect her. Seeing that the Duke of Yue ignored her more and more, the wife of the Duke of Yue became more and more angry.

Although the affairs of the Duke of Yue's Mansion were a matter of the backyard, there is no wall that is impenetrable after all, and some gossip still leaked out, so the memorial impeaching the Duke of Yue was put on the emperor's desk again.

Xiao Yunrou fell silent after hearing the news. Qingci was a little surprised. Shouldn't her master be happy after hearing the news? Why was she so worried?

"The Duke of Yue is an old fox. No matter how much he dotes on Wanqing, he can't do it so openly. There must be something fishy going on. As for the Duke of Yue's wife, even if she was blinded by jealousy, she is the Duke's wife after all, and she has a son. It is impossible for her to leave a notorious Duke's Mansion to her son. I'm afraid these two people did this on purpose."

Qingci was startled and asked quickly, "Isn't Miss Wanqing in danger?"

Xiao Yunrou shook her head. Wanqing should not be in danger. It was just that the wife of the Duke of Yue had a thorn in her eyes. As for the Duke of Yue, she thought for a while and realized that she could only retreat to advance, and let the emperor think that he was old and liked beauty, so that the emperor would be assured of him. Although she didn't know whether the truth was the same as she guessed, she felt that way.

When Pei Lingfeng came back in the evening, Xiao Yunrou told Pei Lingfeng about her speculation, and Pei Lingfeng also agreed.

"The Emperor no longer trusts him. Even if he is just pretending, the Emperor won't be truly reassured."

Only after hearing this did Xiao Yunrou feel relieved.

On the seventeenth day of the first lunar month, Pei Yuanxuan set out for Yunzhou Academy. Because the capital was in such a mess, Pei Lingfeng doubled the number of guards for Pei Yuanxuan. Pei Yuanxuan felt something was wrong but he did not ask. He said goodbye to his parents and brothers obediently. Xiao Yunrou reluctantly sent him to the city gate before returning home.

After the first month of the year, the news about the backyard of the Duke of Yue's mansion somehow spread to the market and became the best gossip among the common people. Xiao Yunrou had not contacted Wanqing once, but Wanqing went to Xiao Yunrou's shop and left a letter. That night, Xiao Yunrou handed the letter to Pei Lingfeng.

"Do you think it's credible?" Pei Lingfeng's expression was unpredictable, and Xiao Yunrou was also puzzled when she first saw him.

"If this is true, it will be the best opportunity to depose Duke Yue and the Crown Prince." Pei Lingfeng was originally thinking about how to get rid of the Crown Prince as soon as possible to save everything in the Marquis' Mansion. Wanqing's letter came at the perfect time.

"This matter is of great importance. If we are not careful, we will all be dragged into it."

Xiao Yunrou was a little worried. Although she had originally wanted to use Wanqing to create some chaos in the Yueguogong Mansion, and then let Wanqing expose the Yueguogong's murder case at the right time, she didn't expect that Wanqing would give her such a big surprise in just one or two months. But she didn't know whether she should believe this surprise, and whether it was a trap set by Yueguogong on purpose.

"Don't have any contact with Wanqing recently. Wait until I verify the truth of this matter before dealing with it." Pei Lingfeng looked at the letter in his hand with cold eyes, and finally threw it into the charcoal brazier.

From this day on, Pei Lingfeng began to get busy. He had to be on duty in the palace during the day, and at night he would just come back to eat a quick meal and go out again, and would only come back in the middle of the night to sleep for two hours.

At midnight, the night was dark and the cold wind was blowing. Pei Lingfeng brought a few trusted secret guards to the place he had spent half a month to find. They sneaked in under the cover of darkness. After entering, Pei Lingfeng discovered that the manor contained weapons for at least 30,000 people. It was unknown how long it took to secretly build so many. Pei Lingfeng's eyes were full of coldness. The accompanying secret guards did not know why their master suddenly showed murderous intent and hatred. Even if he had a grudge against the Duke of Yue, he would not want to kill him just because he saw these things, right?

Several people secretly checked other parts of the manor and found that in addition to weapons, there were also rice and grain, but the people and horses mentioned in the letter were not seen. One of the secret guards whispered to Pei Lingfeng:

"My Lord, we have searched everywhere, but we can't find any horses. We might as well burn them. Without food, we will see how they can train their troops!"

Pei Lingfeng shook his head. What he wanted was evidence, irrefutable ironclad evidence. Burning it would only mean losing money. As long as he had money, he could gather all these things together again. Ironclad evidence was enough to execute his entire clan. Pei Lingfeng made a gesture, and several people left again under the cover of night.

Standing on a hilltop ten miles away from the manor, Pei Lingfeng looked deeply in the direction of the manor. It was a coincidence that they found the manor. Who would have thought that the Duke of Yue and the Crown Prince would privately build an army, and it was only an hour away from the capital. But this place is indeed hidden. The manor was sealed because of an epidemic and has been in ruins for more than ten years. No one would go there.

However, Pei Lingfeng couldn't figure out where the weapons and food were found, but the most important thing was that the troops they secretly gathered were hidden. But he thought, it shouldn't be too far from here, because if it was too far, transporting these food and weapons would be exposed.

"Is there anything else around here that you haven't explored yet?"

The secret guards looked at each other in silence. Liu Feng hesitated and asked, "Could it be that he is still hiding in that manor? For example, he built a secret room underground? Or is there somewhere in the manor that we haven't searched yet?"

When they heard this, they frowned and thought about it. Suddenly, a secret guard whispered, "I remember now. There is a waterfall behind the manor. The plague was caused by the water there. I remember there is a village behind the waterfall. You can get there by crossing the waterfall. But because of the plague, the people there moved away. If we want to hide those people, that's the best place."

No one expected that there would be a village behind the waterfall. If so, it would make sense that they couldn't find the soldiers and horses just now. Pei Lingfeng lowered his eyelids and decided to explore the waterfall again.

However, they were destined not to cross the waterfall, because when they came to the waterfall behind the manor again, they found two masked men guarding it. Now Pei Lingfeng was even more certain that there were soldiers behind the waterfall.

Not wanting to alert the enemy, Pei Lingfeng quietly retreated. After the investigation, the only thing left was how to expose the truth. Pei Lingfeng originally wanted to hand over the evidence directly to the emperor or Prince An, but then he thought that if he just presented the matter in this way, the emperor might deal with it secretly and even become suspicious of him as the Marquis of Zhenyuan. Pei Lingfeng thought about it for a long time and finally decided to let Wanqing do it.

"Wanqing? You want her to go and file a complaint?" Xiao Yunrou was stunned. She didn't expect that Wanqing would have to go in the end.

Pei Lingfeng nodded. If he could solve the problem himself, he would not let Xiao Yunrou get involved in these things. He hugged Xiao Yunrou and whispered to her the possible consequences of the matter. As husband and wife, Xiao Yunrou naturally did not want Pei Lingfeng to get into trouble, let alone the Marquis' Mansion. Although Wanqing was the concubine of the Duke of Yue, if she was meritorious in reporting the incident and someone else pleaded for her, she would definitely be able to get out of this matter.

"I will give her the news. It won't be difficult for her to leave the palace as she is favored by Duke Yue. When she comes out, I will give her the evidence."

"But how to get rid of the people following her? I remember that not only Duke Yue, but also the Duke Yue's wife sent a lot of people to keep an eye on her." Pei Lingfeng was worried that things would not go smoothly.

"Don't worry about that. I own a clothing store. When the time comes, I will ask her to change her clothes and go out through the back door. With your guards protecting her, she can go to the palace gate and beat the drum to protest her injustice."

Xiao Yunrou thought about all possible situations and found no loopholes. Then she asked someone to pass the message to Wanqing when the vegetable vendors were delivering vegetables to the Duke of Yue's Mansion tomorrow.

Wanqing didn't expect Xiao Yunrou to ask her to file a complaint in person. She hesitated for a while, but finally made the decision. In the past two months, she took advantage of the opportunity when Duke Yue was drunk to enter his study and discovered these shocking secrets. There was also the hatred of her family. Although it was not recorded in the book, she had secretly investigated and found the person who secretly prevented her from seeking medical treatment for her father this year.

Now that she could finally take revenge, and do it herself, Wan Qing was extremely excited, and couldn't suppress the smile on her face.

The next morning, Wan Qing pestered Duke Yue and asked him to go out of the house, and Duke Yue naturally agreed.

As Xiao Yunrou planned, in the clothing store, Xiao Yunrou handed the evidence to Wanqing. Seeing Wanqing change her clothes and get on the carriage prepared by the Marquis' Mansion, she smiled faintly. Now, she should go back to the mansion and wait for news. She believed that with these evidences, it would be enough for the emperor to chop off Duke Yue's head several times.
