Sheng Yunrong looked even more puzzled, her brows slightly furrowed, a trace of confusion flashed in her eyes. She turned to Pei Jinxiao beside her, but found that his face was also full of contemplation.

The banquet hall of the Sheng Mansion was brightly lit and the guests were chatting and laughing, but in this lively atmosphere, Sheng Yunrong and Pei Jinxiao's hearts were as if shrouded in ice.

"Brother Pei, what is going on?" Sheng Yunrong asked softly, with a barely perceptible tremor in her voice.

Pei Jinxiao pondered for a moment and slowly said, "Miss Sheng, this matter involves serious matters. I am still investigating. But one thing is certain, there must be something fishy behind this."

Sheng Yunrong nodded slightly, with a hint of determination in her eyes: "Then how does Brother Pei plan to investigate?"

Pei Jinxiao's eyes flashed with a gleam of light: "I will start with the stranger who appeared at the banquet that night. He seems to be inextricably linked to this matter."

At this time, the housekeeper of the Sheng Mansion hurried into the banquet hall with a trace of anxiety on his face: "Miss, there is a man named Li Cheng outside who wants to see you. He said he has something important to tell you."

Sheng Yunrong was slightly startled, then turned to look at Pei Jinxiao: "Brother Pei, do you think Li Cheng has something to do with this matter?"

Pei Jinxiao nodded slightly: "It's possible, we might as well meet each other."

Sheng Yunrong turned around and said to the housekeeper outside: "Bring him in."

After a while, a handsome young man with a sturdy figure came in. He was wearing a dark blue robe with a sword hanging from his waist. As soon as he entered the banquet hall, his eyes fell on Pei Jinxiao.

"Mr. Pei, I heard that the eldest lady of the Sheng Mansion and you are investigating what happened at the banquet that night. I came here for this matter."

Sheng Yunrong smiled slightly: "Mr. Li Cheng, please sit down."

After Li Cheng sat down, Sheng Yunrong couldn't wait to ask, "Sir, what do you know?"

Li Cheng pondered for a moment and said, "At the banquet that night, I noticed a mysterious man in a black cloak. He had been observing silently in the corner, as if he was looking for something. After the banquet, he suddenly disappeared."

Pei Jinxiao immediately asked: "Do you remember what he looks like?"

Li Cheng shook his head: "He was wearing a cloak, so I couldn't see his face clearly. But one thing I can be sure of is that he is very skilled in martial arts and very agile."

Sheng Yunrong frowned: "Could he be someone from the underworld?"

Li Cheng nodded: "It's possible. But I think he is more like a person who came here with a purpose."

Pei Jinxiao's eyes flashed with a gleam of light: "Miss Sheng, I think we need to go to the martial arts world to find this mysterious person."

Sheng Yunrong hesitated slightly, but finally nodded and agreed: "Okay, Brother Pei, then we will go to the arena together."

On the way to Jianghu, Sheng Yunrong and Pei Jinxiao were silent all the way. They were each thinking about their own things, with doubts and expectations in their hearts.

As night fell, they arrived at an inn. Sheng Yunrong and Pei Jinxiao walked into the room, facing each other in silence.

"Miss Sheng, who do you think this mysterious person is?" Pei Jinxiao suddenly asked.

Sheng Yunrong shook her head slightly: "I don't know either. But I know that this matter involves a lot of things, and we must get to the bottom of it."

Pei Jinxiao nodded, with a hint of determination in his eyes: "Yes, we must solve this mystery."

Late at night, Sheng Yunrong lay in bed, unable to fall asleep. She looked at the moonlight outside the window, her heart filled with confusion and anxiety.

"Miss Sheng, what are you thinking about?" Pei Jinxiao's voice sounded in the darkness.

Sheng Yunrong smiled slightly: "Brother Pei, I'm wondering, who is this mysterious person? What is his purpose?"

Pei Jinxiao was silent for a moment, then said, "No matter who he is, we must find him and solve this mystery."

…

Sheng Yunrong's breathing stopped and her face turned pale. What she saw before her was a scene she had never dared to imagine - in the main hall of Sheng's mansion, Prince Jing Pei Jinxiao was chatting with her father Sheng Mingyuan, and the atmosphere was surprisingly harmonious.

Sheng Yunrong hurriedly sorted out her emotions and slowly walked into the main hall. Pei Jinxiao raised his head, his eyes were like torches, he looked at her for a moment, and then quickly looked away. Sheng Yunrong's heartbeat accelerated, she forced herself to remain calm, bowed to her father, then turned to Pei Jinxiao and smiled slightly: "Your Highness Prince Jing, you are here."

Pei Jinxiao nodded slightly, with a barely perceptible tenderness in his eyes: "Miss Sheng, long time no see."

Sheng Mingyuan laughed and tried to smooth things over, "Rong'er, why don't you show His Royal Highness Prince Jing a seat?"

Sheng Yunrong hurriedly brought a chair and placed it next to Pei Jinxiao. She tried her best to make her movements natural, but she couldn't completely hide her inner nervousness.

After sitting down, Pei Jinxiao glanced at Sheng Yunrong and asked, "Miss Sheng, how are you doing recently?"

Sheng Yunrong smiled slightly, trying to make herself look relaxed: "TOEFL, everything is fine. Your Highness, despite being very busy with government affairs, still took the time to visit our Sheng Mansion. I am really grateful."

Pei Jinxiao smiled, and the seriousness in his eyes faded a little: "This king is indeed busy with affairs, but Sheng Mansion is the place of my good friend after all, how can I not come to take a look."

Sheng Mingyuan laughed loudly after hearing this: "Your Highness, you are too kind. The Sheng Mansion is not worthy of the title of 'a place of good friends'."

Pei Jinxiao stopped smiling and said sternly, "Sir Sheng, this is wrong. The Sheng family plays an important role in the court. It is an honor for me to make friends with them."

Sheng Yunrong looked at Pei Jinxiao and secretly sighed in her heart: This man is indeed extraordinary.

In the following time, the three chatted about government affairs and family matters in a harmonious atmosphere. Sheng Yunrong found that Pei Jinxiao was not only knowledgeable and talented, but also had a humorous conversation that made people feel like spring breeze. She couldn't help but have a good impression of Pei Jinxiao.

However, at this moment, a guard rushed in with a secret letter in his hand. He presented it to Sheng Mingyuan, who opened it and his face suddenly became solemn.

Pei Jinxiao saw this and asked, "Master Sheng, what happened?"

Sheng Mingyuan pondered for a moment and handed the secret letter to Pei Jinxiao: "Your Highness, this is an urgent report from the border. The Huns have invaded the border and the situation is critical."

Pei Jinxiao took the secret letter, glanced at it, and his eyes suddenly became sharp: "Lord Sheng, this matter is of great importance. I will set off immediately and return to the capital."

Sheng Yunrong's heart tightened, and she hurriedly said, "Your Highness, you must be careful."

Pei Jinxiao glanced at her and smiled, "Don't worry, Miss Sheng, I won't take risks easily."

Sheng Mingyuan stood up and bowed to Pei Jinxiao: "Your Highness, the country is in trouble. As a prince, you should step forward. The Sheng family will also do its best to contribute to the country."

Pei Jinxiao nodded and thanked Sheng Mingyuan: "Don't worry, Lord Sheng, I will live up to your expectations."

After that, Pei Jinxiao turned and left. Sheng Yunrong looked at his back, with mixed emotions in her heart.

Finally, Pei Jinxiao returned to the capital as promised. Sheng Yunrong greeted him at the gate of Sheng Mansion, and looked at his brave and vigorous figure with respect in her heart.
