Sheng Yunrong's eyes flashed with dissatisfaction, but she did not ask any more questions. She walked gently to Pei Jinxiao, sat down, and said, "Pei Jinxiao, I heard that you are investigating something recently."

Pei Jinxiao's eyes flashed with something strange. He looked at Sheng Yunrong and said calmly, "Miss Sheng is really well-informed. Yes, I'm investigating an old case."

"Old case?" A hint of curiosity flashed in Sheng Yunrong's eyes. "What old case?"

Pei Jinxiao sighed slightly and said, "This is an old case of great importance that involves the honor of my family. However, I cannot tell you now."

A trace of disappointment flashed across Sheng Yunrong's eyes. She looked at Pei Jinxiao and said firmly, "Pei Jinxiao, you don't trust me?"

Pei Jinxiao shook his head gently and said, "Miss Sheng has misunderstood. I am just worried that this matter is too involved and will affect you."

Sheng Yunrong's eyes flashed with warmth. She gently held Pei Jinxiao's hand and said, "Pei Jinxiao, I believe you. No matter what old case it is, I will support you."

Pei Jinxiao looked at Sheng Yunrong, a trace of gratitude flashed in his eyes. He gently held Sheng Yunrong's hand and said, "Thank you, Miss Sheng."

The two smiled at each other, and the atmosphere became warm. At this time, a servant came in with an envelope in his hand.

"Your Majesty, this is a letter from the capital."

Pei Jinxiao took the envelope, opened it, and his face suddenly became solemn. He gently put the envelope down and said to Sheng Yunrong, "Miss Sheng, I have some things to deal with. You go back first."

A trace of worry flashed across Sheng Yunrong's eyes. She looked at Pei Jinxiao and said softly, "Pei Jinxiao, you..."

Pei Jinxiao gently patted Sheng Yunrong's hand and said, "Don't worry, I'll be fine. You can go back first."

Sheng Yunrong nodded helplessly and turned to leave. Pei Jinxiao looked at Sheng Yunrong's back, with a hint of determination in his eyes.

Sheng Yunrong returned to her room, but she still couldn't calm down. She looked out the window at Prince Jing's Mansion and thought to herself, "Pei Jinxiao, what are you hiding?"

As night fell, the lights in Prince Jing's mansion were bright. Sheng Yunrong quietly came to Pei Jinxiao's study, only to find that the door was closed. She gently pushed the door open and saw Pei Jinxiao sitting at the desk, holding the envelope in his hand.

"Pei Jinxiao, what are you doing?" Sheng Yunrong asked coldly.

Pei Jinxiao raised his head, a hint of surprise flashed in his eyes. He looked at Sheng Yunrong and said softly, "Miss Sheng, why are you here?"

Sheng Yunrong's eyes flashed with determination. She walked up to Pei Jinxiao and said, "Pei Jinxiao, tell me, what are you hiding?"

Pei Jinxiao looked at Sheng Yunrong, a hint of hesitation flashed in his eyes. He gently put down the envelope and said, "Miss Sheng, I..."

A trace of disappointment flashed across Sheng Yunrong's eyes. She looked at Pei Jinxiao and said firmly, "Pei Jinxiao, if you do this again, I will leave you."

Pei Jinxiao's heart trembled. He looked at Sheng Yunrong with a trace of pain in his eyes and said, "Miss Sheng, I... I do have a secret, but I can't tell it."

Sheng Yunrong's eyes flashed with determination. She looked at Pei Jinxiao and said, "Pei Jinxiao, if you do this again, I will check it myself."

Pei Jinxiao's heart tightened. He looked at Sheng Yunrong, a hint of determination flashed in his eyes, and said, "Okay, I'll tell you."

Pei Jinxiao handed the envelope to Sheng Yunrong and said, "This is a letter of complaint, reporting that someone in my family is involved in treason."

Sheng Yunrong's eyes widened. She looked at Pei Jinxiao with a flash of shock in her eyes. She gently put down the envelope and said, "Pei Jinxiao, this... how is this possible?"

Pei Jinxiao's eyes flashed with pain. He looked at Sheng Yunrong and said, "I know, this makes me painful too. But I can't just sit there and do nothing."

Sheng Yunrong looked at Pei Jinxiao, a hint of determination flashed in her eyes, and said: "Pei Jinxiao, I will find out the truth with you."

…

Sheng Yunrong was wondering when she saw two maids walking towards her from the other side of the path, teasing her.

Sheng Yunrong frowned slightly, and her doubts grew. She slowed down her pace involuntarily and quietly observed the two maids. They were talking and laughing, and from time to time they would secretly glance at her, as if they were discussing some secret.

"Xiao Cui, have you heard? Miss Sheng seems to be worried about something today and has been wandering around in the garden." One of the maids whispered.

"Yes, this is the first time I see her so distraught." Another maid said with a hint of curiosity in her tone.

Sheng Yunrong was shocked. She knew that the two maids were close to Pei Jinxiao, and their words might have reached the ears of Prince Jing. She took a deep breath, tried to sort out her emotions, and then slowly walked towards the two maids.

"What are you talking about?" Sheng Yunrong's voice was calm and soft, but with a barely perceptible coldness.

The two maids immediately stopped smiling and bowed their heads, "Miss Sheng, we were just chatting."

Sheng Yunrong smiled slightly, but her eyes revealed a hint of sharpness: "Please avoid talking about my name, otherwise it will get to Prince Jing's ears and cause unnecessary misunderstandings."

The two maids blushed and apologized quickly: "Miss Sheng, we know we were wrong."

Sheng Yunrong nodded and was about to leave when she saw Pei Jinxiao coming over from the other side. He was wearing a blue gown, with an upright figure and a stern look between his eyebrows. When he saw Sheng Yunrong, he smiled slightly, with a hint of doubt in his eyes.

"Miss Sheng, what's wrong with you?" Pei Jinxiao asked.

Sheng Yunrong collected her thoughts and smiled calmly: "Nothing, just some minor troubles."

Pei Jinxiao frowned slightly, seemingly dissatisfied with Sheng Yunrong's answer. He turned to look at the two maids, with a hint of warning in his eyes.

"You go down first." Pei Jinxiao said coldly.

The two maids retreated tremblingly, and Sheng Yunrong couldn't help but feel a little nervous. She knew that Pei Jinxiao was an extremely smart man, and she might be seen through by him.

"Miss Sheng, you seem to be worried about something." Pei Jinxiao's voice sounded softly, with a hint of concern.

Sheng Yunrong bit her lower lip lightly, hesitated for a moment, and finally made up her mind: "Prince Jing, there are indeed some things I can't figure out. I...I seem to have heard some rumors about you and me."

Pei Jinxiao smiled slightly, with a hint of teasing in his eyes: "Oh? What rumor?"

"Say...say that there is a secret affair between us." Sheng Yunrong's voice became lower and lower, and her face turned a little red.

Pei Jinxiao laughed, and the teasing in his eyes became stronger: "Miss Sheng, you misunderstood. Those rumors are just idle talk from bored people, you don't have to take them to heart."

Sheng Yunrong raised her head and looked at Pei Jinxiao firmly: "Prince Jing, I know that I am of low status and not worthy of you. But I really like you. I... I want to know, what do you think of me?"

Pei Jinxiao's expression changed slightly, the teasing in his eyes disappeared, replaced by a hint of seriousness. He looked at Sheng Yunrong quietly, and after a moment, he sighed softly.

"Miss Sheng, you are a smart and beautiful woman, worthy of anyone's love. But I... as the Prince of Jing, I have too much responsibility to bear, and I cannot make a promise easily. Do you understand?"
