Xiang Zhu hurried into Sheng Yunrong's boudoir, the joy on his face was beyond words. Sheng Yunrong was sitting by the window, holding a thread-bound book in her hands, her brows slightly furrowed, as if she was thinking about something. When she heard Xiang Zhu's footsteps, she looked up, a hint of doubt flashed in her eyes.

"Miss, guess what? I just met a guest in the garden who actually knew the secret of our Sheng Mansion!" Xiang Zhu said excitedly, with excitement that was hard to conceal in his voice.

Sheng Yunrong put down the book and smiled slightly, with a hint of curiosity in her eyes: "Oh? Who is the guest? What secret did he know?"

Xiang Zhu walked up to Sheng Yunrong, his face full of joy: "That guest claimed to be a man of the underworld. He said he knew where the treasure of our Sheng Mansion was hidden, and he was willing to help us find it."

Sheng Yunrong raised her eyebrows, a hint of doubt flashed in her eyes: "A gangster? Does he know about the treasure? Is there something fishy going on?"

"Miss, I also find it a little strange, but that guest doesn't look like he is lying. The location of the treasure he described coincides with the legend of our Sheng Mansion. I think we might as well meet him and find out the truth." Xiang Zhu suggested.

Sheng Yunrong pondered for a moment and nodded: "Okay, then please invite him to meet in the flower hall. However, Xiang Zhu, you must always pay attention to the guest's behavior, just in case."

"Yes, Miss, I will be careful." Xiang Zhu agreed and turned around to make arrangements.

Soon, the man was led to the flower hall. Sheng Yunrong sat in the main seat, Xiang Zhu stood beside her, and the other maids retreated behind the screen. The man walked into the flower hall, bowed, and said loudly: "Miss Sheng, I am Zhang Wuji, and I have come to tell you a secret about the treasure of Sheng Mansion."

Sheng Yunrong smiled slightly and motioned Zhang Wuji to sit down: "Mr. Zhang, please speak."

After Zhang Wuji sat down, he slowly said, "The treasure of Sheng Mansion is actually in the back garden of Sheng Mansion. There is a rockery there, and behind the rockery there is a secret passage, and at the end of the secret passage is the treasure."

Sheng Yunrong's eyes flashed with surprise. She didn't expect that this person in the underworld could tell the exact location of the treasure. She asked, "Mr. Zhang, how did you know this secret?"

Zhang Wuji smiled slightly: "I have been in the martial arts world for many years and learned this secret by chance. I know the background of the Sheng Mansion very well, so I came to tell the young lady."

Sheng Yunrong pondered for a moment and then asked, "Does Mr. Zhang know the specific contents of this treasure?"

Zhang Wuji shook his head: "I don't know the exact contents of the treasure, but according to rumors, there is a magical weapon in the treasure that is priceless."

A trace of greed flashed in Sheng Yunrong's eyes. She knew that this magic weapon was exactly what she had always dreamed of. She glanced at Xiang Zhu, who immediately understood and walked up to Zhang Wuji and asked in a low voice, "Mr. Zhang, are you willing to help us find this magic weapon?"

Zhang Wuji smiled slightly: "Since I already know this secret, I will naturally help you. However, I have a condition."

Sheng Yunrong raised her eyebrows: "Mr. Zhang, please speak."

Zhang Wuji said, "I hope to go with you to where the treasure is and witness the unearthing of the magic weapon together."

Sheng Yunrong pondered for a moment and finally agreed to the condition. Then Zhang Wuji, Sheng Yunrong, Xiang Zhu and others went to the back garden to look for the treasure.

Behind the rockery in the back garden, Zhang Wuji pointed to an inconspicuous stone and whispered, "It's right here." Sheng Yunrong and others worked together and after great effort, they finally moved the stone away, revealing a secret passage.

They walked along the secret passage and soon came to a secret room. In the middle of the secret room, there was a huge box. Sheng Yunrong and others excitedly opened the box and saw a golden long sword lying in the box.

Sheng Yunrong picked up the sword, a hint of surprise flashed in her eyes: "This is the legendary magic weapon!"

Zhang Wuji smiled and said, "Congratulations, Miss, you have finally found a magic weapon. I will take my leave now."

Sheng Yunrong looked at Zhang Wuji's departing back and felt secretly grateful in her heart.

…

Sheng Yunrong's eyes revealed a trace of anxiety. She held Xiang Zhu's hand tightly, her voice trembling slightly: "Xiang Zhu, where is my brother? Where did he go?"

Xiang Zhu shook her head slightly, with a bit of worry on her face: "Miss, Master Sheng Hongye has not returned to his room to rest since the banquet ended last night. I have asked around, but there is still no news."

Sheng Yunrong's face turned even paler. She bit her lower lip and turned to walk towards the study room of Sheng Mansion. Xiang Zhu followed closely behind her. They entered the study room together, but found that the study room was empty and there was an unfinished letter on the desk.

"What is this?" Sheng Yunrong picked up the letter, frowning.

The letter read: "Dear sister, I have some things to take care of and may be away for a while. Don't worry about me, just take good care of yourself and wait for me to come back."

Sheng Yunrong held the letter tightly in her hand, with a gleam of determination in her eyes: "Xiang Zhu, let's split up and look for him. No matter what, I want to find my brother."

Xiang Zhu nodded, and the two of them immediately split up. Sheng Yunrong came to the back garden of the Sheng Mansion, while Xiang Zhu went to the warehouse of the Sheng Mansion.

Sheng Yunrong searched the back garden but still couldn't find Sheng Hongye. She sat on a bench in the garden, feeling increasingly anxious. At this moment, Xiang Zhu hurried over, looking somewhat panicked.

"Miss, I just came back from the warehouse and found that a large amount of valuables were missing from the warehouse." Xiang Zhu said in a low voice.

Sheng Yunrong stood up suddenly, a trace of doubt flashed in her eyes: "Property lost? Could my eldest brother's departure be related to this?"

The two decided to go back to the study and think about the whole thing carefully. After returning to the study, Sheng Yunrong put the letter on the table, tapped the table lightly with her hands, and fell into deep thought.

Xiang Zhu looked at Sheng Yunrong, feeling worried: "Miss, what should we do next?"

Sheng Yunrong raised her head, a hint of determination flashed in her eyes: "Xiang Zhu, I suspect that my eldest brother's departure is related to the internal problems of the Sheng Mansion. We need to find out the truth before we can find my eldest brother."

Xiang Zhu nodded in agreement: "Miss, I will do my best to assist you."

At night, Sheng Yunrong and Xiang Zhu quietly followed Sheng Huairen and came to the back door of Sheng's house. They saw Sheng Huairen talking to the mysterious man, and then the mysterious man handed a package to Sheng Huairen.

Sheng Yunrong and Xiang Zhu immediately realized that the package might contain clues about Sheng Hongye's departure, so they decided to intercept the package.

After a fierce chase, Sheng Yunrong and Xiang Zhu successfully intercepted Sheng Huairen and took back the package. When they opened the package, they found another letter left by Sheng Hongye.

The letter read: "Dear sister, I know you will find this letter. I left the Sheng Mansion to investigate Sheng Huairen's conspiracy. Please be careful and protect yourself. Wait for me to come back."

After reading the letter, Sheng Yunrong and Xiang Zhu finally understood Sheng Hongye's good intentions. They decided to expose Sheng Huairen's conspiracy and wait for Sheng Hongye's return.
