Sheng Yunrong's face changed and she said, "Servants? But the servants in our Sheng Mansion have detailed files. It's impossible for a stranger to sneak in."

Ah Tie said: "I was also confused at first, but later I found that the servant had a special mark on his body, which seemed to be a symbol of some kind of identity."

Sheng Yunrong's eyes flashed with a gleam of light, and she asked, "Special mark? What does it look like?"

Ah Tiedao: "It's a small triangular piece of iron with strange patterns carved on it."

Sheng Yunrong immediately ordered: "Master Tu Su, you take people to investigate this matter immediately. No matter what, we must find that piece of iron."

Tu Subo took the order and left. Sheng Yunrong looked at A Tie and said, "Mr. A Tie, thank you for the clue. If this matter can be successfully resolved, the Sheng family will reward you handsomely."

Ah Tie smiled and said, "Miss Sheng, you are too polite. I am just doing my best to serve the Sheng family."

Sheng Yunrong said: "Then I'll trouble you. In the meantime, you will stay in the Sheng Mansion and assist us in the investigation."

Ah Tie agreed, and everyone dispersed. Sheng Yunrong looked at Tu Subo's departing back, and secretly vowed in her heart that she must find out the truth and clear the Sheng family of the injustice.

As night fell, the lights in Sheng Mansion were on. Sheng Yunrong sat in the study, the teacup in her hand trembling slightly.

…

"Of course it's true." Sheng Yunrong nodded, with a faint smile on her lips. She gently brushed her sleeves, her eyes revealing an unquestionable confidence. Tu Subo looked at her, with a hint of admiration in his eyes.

The garden of Sheng Mansion was full of spring. Flowers were in full bloom, and bees and butterflies were fluttering. Sheng Yunrong and Tu Subo walked side by side on the path, while the maid Xiang Zhu followed closely behind them, carefully observing the surroundings.

"Miss, do you really believe that Master Tu Su can help us solve this trouble?" Xiang Zhu couldn't help but ask, with some worry in his eyes.

Sheng Yunrong smiled slightly and turned to look at Xiang Zhu: "Xiang Zhu, you don't know Tu Subo yet. He is very smart and thoughtful. I believe he can find a solution to the problem."

When Tu Subo heard this, he smiled modestly: "Miss, you are too kind. I only know a little bit and need to work harder."

Sheng Yunrong patted Tu Subo's shoulder gently, her eyes full of trust: "I believe you, Tu Subo."

The three of them continued walking and came to a corner of the garden. There was a small pavilion with a set of exquisite tea sets placed in it. Sheng Yunrong motioned for them to sit down, and then personally poured tea for Tu Subo and Xiang Zhu.

"Speaking of which, this matter is indeed a bit tricky." Sheng Yunrong sighed lightly, her eyes becoming a little heavy, "The reputation of the Sheng Mansion has been damaged, and I have to reconsider what path to take in the future."

Tu Subo picked up the teacup, blew on it gently, and then said, "Miss, you don't have to worry too much. As long as we find out the mastermind and clear the name of the Sheng family, the reputation will naturally be restored."

Sheng Yunrong nodded, with a hint of determination in her eyes: "Yes, we must find out the mastermind behind this."

At this time, Xiang Zhu suddenly interrupted and said, "Miss, do you think it was done by someone inside the Sheng Mansion?"

Sheng Yunrong and Tu Subo looked at Xiang Zhu at the same time, with some surprise in their eyes. Sheng Yunrong shook her head slightly: "I don't believe that anyone in the Sheng Mansion would betray the family. But this possibility cannot be ruled out."

Tu Subo pondered for a while and said, "Miss, I think we can start from two aspects. One is to investigate the Sheng Mansion to see if anyone is behaving abnormally; the other is to investigate externally to see if anyone has any grudges against the Sheng Mansion."

Sheng Yunrong nodded slightly, with a hint of appreciation in her eyes: "Tu Subo, you really have a way. Then let's act according to your plan."

One night, Tu Subo hurried back to the Sheng Mansion and found Sheng Yunrong: "Miss, I found some clues. Someone is secretly manipulating all this and trying to destroy the reputation of the Sheng Mansion."

Sheng Yunrong's eyes narrowed, and she asked seriously, "Who is it?"

Tu Subo shook his head: "It's not certain yet, but I have found some clues. I will continue to investigate and will definitely find the mastermind behind it."

Sheng Yunrong patted Tu Subo on the shoulder, her eyes full of encouragement: "I believe in you, Tu Subo. The reputation of the Sheng Mansion is in your hands."

Tu Subo nodded confidently and turned to leave. Sheng Yunrong looked at his back and felt a warm feeling in her heart.

However, the development of the matter is far beyond their expectations. Just when Tu Subo is about to find out the mastermind, a sudden change plunges the Sheng Mansion into an unprecedented crisis.

Sheng Yunrong stood in front of the gate of Sheng Mansion, watching Tu Subo and Xiang Zhu leave in a hurry, her heart full of worry.

As night fell, the lights in Sheng Mansion were on. Sheng Yunrong sat in the hall, waiting for news from Tu Subo and Xiang Zhu.

Sheng Yunrong didn't sleep a wink that night. She looked at the starry sky outside the window and prayed silently in her heart.

…

Sheng Yunrong took the things from Xiang Zhu, picked up some loose silver, and decided to set off. Her eyes flashed with determination. This was the first time she stepped out of the house alone to find the man in her heart - Tu Subo.

In front of the gate of Sheng Mansion, Sheng Yunrong stopped and looked back at the mansion where she had lived for eighteen years, with a complex emotion in her heart. She took a deep breath, turned around and walked out the door.

"Miss, have you really decided to leave?" Xiang Zhu's eyes were full of worry. She followed Sheng Yunrong closely and asked in a low voice.

Sheng Yunrong smiled slightly, looked into Xiang Zhu's eyes, and patted her hands gently, "Xiang Zhu, I know you are worried about me, but I have to find him. This is the obsession in my heart, and I have to solve it."

Xiang Zhu looked at Sheng Yunrong's back, with a hint of determination in her eyes. Once her master made a decision, there would be no turning back. She could only support her silently and accompany her.

Sheng Yunrong and Xiang Zhu came to the bustling city, they shuttled through the crowd, looking forward to Tu Subo's appearance. Suddenly, Sheng Yunrong's eyes lit up, she saw Tu Subo, he was at the door of a bookstore, holding a book in his hand, reading attentively.

Sheng Yunrong's heartbeat quickened. She held Xiang Zhu's hand tightly, took a deep breath, and walked towards Tu Subo.

"Tu Subo." Sheng Yunrong stood in front of Tu Subo, her voice trembling slightly.

Tu Subo raised his head and saw Sheng Yunrong. There was a flash of surprise in his eyes, and then joy. "Sheng Yunrong, why are you here?"

Sheng Yunrong smiled slightly and looked into Tu Subo's eyes. She felt that the obsession in her heart had been resolved and she finally found the person in her heart.

"Tu Subo, I came to see you. I want to know if the person in your heart is me." Sheng Yunrong's voice was firm and bright.

Tu Subo looked at Sheng Yunrong, his eyes full of surprise. He held Sheng Yunrong's hand tightly, "Sheng Yunrong, I have been waiting for you. The person in my heart is you."

When Sheng Yunrong heard this, her heart was filled with joy. She held Tu Subo's hand tightly, with a look of happiness in her eyes.

Xiang Zhu looked at them and felt happy in her heart. Her master had found the person of her dreams, and her mission was accomplished.
