The two of them studied ancient books in the room, and the distance between them became closer and closer. Tu Subo observed Sheng Yunrong's expression from time to time, and found that there was a gleam of wisdom in her eyes, and he couldn't help but feel secretly happy.

Suddenly, Sheng Yunrong raised her head, a hint of doubt flashed in her eyes: "Tu Subo, have you noticed that the formation in this book is somewhat similar to the formation of our Sheng family?"

Tu Subo was stunned, thought about it carefully, and nodded: "Indeed. Miss Sheng, do you think this is a coincidence?"

Sheng Yunrong's eyes flashed with a gleam of light: "Perhaps, this book has some connection with the Sheng family. We might as well explore it in depth."

The two returned to their research, talking to each other more and more, with more and more expressions. Sometimes they frowned in thought, sometimes they were surprised and delighted. Before they knew it, it was already late at night.

Sheng Yunrong looked at Tu Subo with a hint of gratitude in her eyes: "Tu Subo, thank you. Without you, I might not have discovered the secret of this book."

Tu Subo smiled slightly, his eyes showing deep affection: "Miss Sheng, this is what I should do. If we discuss it together, we can find the answer faster."

In the night, the two figures intertwined, like a beautiful painting.

In Tu Subo's room, the simple furniture exuded a faint sandalwood scent, and the bookshelves were filled with various classics. Sheng Yunrong, wearing a lavender silk dress, gently pushed open the door, and what came into her eyes was Tu Subo's ecstatic expression.

"What?" Tu Subo's eyebrows were raised with a twinkle in his eyes, "Really?"

Sheng Yunrong nodded gently and smiled: "Of course what I said is true. I heard from my father that you have been studying a mysterious ancient book recently, is that right?"

Tu Subo showed a smug look on his face. He walked to the bookshelf, took down a worn book, and handed it to Sheng Yunrong: "Yes, I am studying this "Xuan Yue Secret Record". It is said that this book records a long-lost secret technique that can help people break through their limits and improve their cultivation."

Sheng Yunrong flipped through the book, a hint of curiosity flashing in her eyes: "Then how did you find this book?"

Tu Subo's expression became serious. He looked at Sheng Yunrong and said, "Actually, all this is thanks to you. The legend you mentioned accidentally that day gave me inspiration. I started to look up various ancient books and finally found this "Xuan Yue Secret Records."

Sheng Yunrong smiled slightly, her eyes full of admiration: "It seems that your talent is well-deserved. However, can this book really improve my cultivation?"

Tu Subo nodded, his eyes gleaming with determination: "I believe it will work. I have been practicing according to the method in the book for a while, and I feel that my body and mind have undergone great changes."

Sheng Yunrong's expression turned serious, and she said softly, "Then you must be careful not to let this change affect your character."

Tu Subo smiled, his eyes full of confidence: "Don't worry, I know what I'm doing. And, with you by my side, I'm even more confident."

The two smiled at each other, and the atmosphere became warm and harmonious. Sheng Yunrong gently patted Tu Subo on the shoulder and encouraged him: "Then come on, I believe you will succeed."

Tu Subo nodded, his eyes firm: "Thank you, Yunrong. I will try my best."

In the room, the two continued to discuss the mysteries in "Xuan Yue Mi Lu", laughing from time to time. The sunlight shone on them through the window, forming a beautiful silhouette. In this corner full of wisdom and love, they pursued a higher level of cultivation together and spent every beautiful moment together.

As time went by, Sheng Yunrong noticed that Tu Subo's expression became more and more serious, even a little painful. She asked with concern: "Bo, what's wrong with you? Is there something wrong with your cultivation?"

Tu Subo shook his head gently, trying to calm himself down: "It's okay, I just encountered some bottlenecks in my practice. I will slowly adjust."

Sheng Yunrong looked at him worriedly, her heart full of contradictions. She knew that Tu Subo's character determined that he would choose to persevere when faced with difficulties. But she was also worried that he would be hurt.

Tu Subo saw Sheng Yunrong's worry, he smiled and held her hand: "Don't worry, I will be fine. As long as you are by my side, I have infinite strength."

Sheng Yunrong nodded slightly, her eyes full of trust and determination.

Sheng Yunrong walked in lightly, her eyes sparkling with curiosity and anticipation. Tu Subo stood in front of the desk, holding a piece of letter in his hand, his joy was beyond words.

"What?" Tu Subo's eyebrows were raised with a gleam of disbelief in his eyes. "You really found Miss Xu?"

Sheng Yunrong nodded gently, and a gentle smile appeared on the corner of her mouth: "Yes, I found her. She lives a simple and secluded life in a small village in the south of the Yangtze River."

Tu Subo's eyes flashed with excitement, and his hand holding the letter trembled slightly: "She... is she really willing to come back?"

Sheng Yunrong nodded slightly and said, "She mentioned you, Tu Subo. She said she always remembered you."

Tu Subo's face showed a complex expression, with both joy and worry. He slowly walked to the window, looked at the mottled raindrops outside the window, and whispered: "Is she doing well?"

Sheng Yunrong said softly: "She is fine, just a little lonely."

Tu Subo turned his head and looked at Sheng Yunrong firmly: "I'm going to see her."

Sheng Yunrong smiled slightly, with a hint of encouragement in her eyes: "I'll go with you."

The atmosphere between the two became warm and tacit. Sheng Yunrong walked to Tu Subo's desk, gently brushed the dust off the desk, and said, "Tu Subo, do you know? I have always been curious about how many secrets are hidden in your study."

Tu Subo smiled slightly, with a hint of mischief in his eyes: "Secrets? Maybe a lot, but the most important secret is about Miss Xu."

Sheng Yunrong nodded slightly, a hint of emotion flashed in her eyes: "I understand. So, when do we set off?"

Tu Subo pondered for a moment and said, "Early tomorrow morning."

Sheng Yunrong smiled slightly. She walked to Tu Subo and gently held his hand: "Then, we will stay here tonight and prepare for the upcoming journey."

Tu Subo nodded gently, a hint of expectation flashing in his eyes: "Okay."

As night fell, the candlelight in the study flickered. Sheng Yunrong and Tu Subo sat opposite each other, their eyes met, as if at this moment, all words became superfluous. Tu Subo gently picked up an ancient book, turned a page, and whispered: "This is the book that Miss Xu once gave me, and I have always treasured it."

Sheng Yunrong took the book, and her fingers gently slid across the pages, as if she could feel Miss Xu's tenderness and affection. She looked up at Tu Subo, with a gleam of determination in her eyes: "Tu Subo, we will definitely find Miss Xu and bring her back to us."

Tu Subo smiled slightly, his eyes full of confidence: "Yes, we will."

The candlelight flickered, and the emotions between the two people flowed slowly in the quiet study, as if time went back to that hopeful past.
