"Niannian, high school life is different from junior high. You need to be more independent and learn to take care of yourself. Grandpa isn't by your side, so you need to study hard, okay?" Grandpa Fu's voice was full of deep affection.

Niannian nodded obediently and smiled, "Grandpa, don't worry, I'll take good care of myself. You should also take care of yourself and not overwork yourself."

Grandpa Fu nodded in satisfaction and watched Niannian walk into the campus. At that moment, sunlight filtered through the leaves of the campus trees, falling on Niannian and adding to her youthful charm.

In ancient times, Pei Yunjing composed himself and said to Jiusheng, "Let her in."

A moment later, Miss Shen entered the room, a hint of anxiety in her eyes. Upon seeing Pei Yunjing, she gave a slight bow: "Young Master Yunjing, I heard you didn't sleep a wink last night, so I came to see you."

Pei Yunjing smiled and replied, "Thank you for your concern, Miss Shen. I'm fine. May I ask what brings you here, Miss Shen?"

Ms. Shen hesitated for a moment, then mustered her courage and said, "Actually, I wanted to ask about Niannian's situation. She's registering for high school today, and I'm worried she won't adapt well to the new environment."

Upon hearing this, Pei Yunjing felt a touch of warmth at Miss Shen's concern, but he maintained a calm expression: "Miss Shen, don't worry, Niannian will take good care of herself. Besides, she has many people around her who care about her."

The two chatted like this, but Pei Yunjing's heart remained restless. He knew he had to let go of those inappropriate feelings and focus on Nian Nian's growth and future.

In modern times, Nian Nian begins her new high school life. Full of curiosity, she explores every corner of the campus, makes new friends, and embarks on new challenges. Meanwhile, in ancient times, Pei Yun Jing silently watches over Nian Nian, praying for her happiness and success. Two times, two hearts, forever intertwined.

In modern times, Niannian's high school life gradually gets on track. She finds that high school courses are more in-depth and demanding than those in junior high, but she doesn't back down; instead, she studies even harder. Amidst her busy studies, Niannian often thinks of Pei Yunjing, the brother in her dreams; his image lingers in her heart.

One day after school, Niannian walked out of the school gate with her classmates when she suddenly saw a familiar figure standing not far away. It was Uncle Li, an old friend of Grandpa Fu and a distant relative of Niannian. Uncle Li was holding an antique-looking box, seemingly waiting for someone.

Niannian stepped forward and asked curiously, "Uncle Li, what are you doing here?"

When Uncle Li saw Niannian, a kind smile appeared on his face: "Niannian, I heard you were studying here, so I came to see you. This box was given to me by your grandfather. He said it's your family heirloom."

Niannian took the box, her heart filled with doubt. She thanked Uncle Li and rushed home to open the box. Inside was an antique bronze mirror, the very same phoenix bronze mirror she had seen in her dream.

In ancient times, Pei Yunjing was overjoyed to learn that Nian Nian was living a successful life in the modern world. However, his own life took a turn for the worse. Someone in the court was secretly plotting against him, putting his position in jeopardy. Pei Yunjing knew that this crisis had to be handled carefully, otherwise it would affect Nian Nian.

Just when Pei Yunjing was in trouble, Miss Shen came to his side again, expressing her willingness to help him. It turned out that Miss Shen's family held a pivotal position in the court, and she was willing to use her family's power to lend Pei Yunjing a hand.

Pei Yunjing was extremely grateful, but he also understood that this would leave him indebted to Miss Shen. With Miss Shen's help, Pei Yunjing successfully resolved the crisis, but he also realized that he could no longer remain passive and had to take the initiative to pave a more solid path for Niannian's future.

While studying the Phoenix Bronze Mirror, modern-day Niannian unexpectedly discovers the secret behind it. It turns out this bronze mirror possesses the power to travel through time. A bold idea arises in Niannian's mind: she must return to ancient times, find Pei Yunjing, and tell him her true identity.

On a full moon night, following the instructions on the back of the bronze mirror, Niannian successfully traveled through time and arrived in ancient times. She found Pei Yunjing, only to be surprised to discover that he was discussing marriage with Miss Shen. Niannian was filled with complex emotions; she didn't know whether she should reveal the truth.

Pei Yunjing was also quite surprised to see Niannian appear. After learning Niannian's true identity, he was caught in a deep struggle. On one side was Niannian, the woman he had always regarded as a younger sister; on the other side was Miss Shen, his savior. How should Pei Yunjing choose to remain true to his original intentions while also repaying Miss Shen's kindness? All of this awaited Pei Yunjing's answer.

Pei Yunjing's heart was in turmoil. He looked at Niannian, his eyes filled with complex emotions. He knew that Niannian's appearance had changed everything, and he could no longer escape his true feelings. He turned to Miss Shen, bowed deeply, and said firmly, "Miss Shen, I will never forget your great kindness. But I must tell you, Niannian is more than just a sister to me."

Miss Shen's expression changed slightly, but she quickly regained her composure. She had long seen that the feelings between Pei Yunjing and Nian Nian were extraordinary, but she had always been unwilling to face it. She sighed softly and said, "Yunjing, I understand your feelings. Since that's the case, I won't force you. I only hope that you can find true happiness."

Niannian looked at Miss Shen, her heart filled with gratitude. She stepped forward and took Miss Shen's hand: "Miss Shen, I admire your magnanimity. I will remember your kindness, and I hope you can find your own happiness."

Pei Yunjing and Nian Nian looked at each other, their eyes filled with determination. Pei Yunjing knew that their feelings had transcended the boundaries of time and space, and he could no longer let Nian Nian be alone.

At this time, the situation in the imperial court also changed. With the help of Miss Shen's family, Pei Yunjing successfully consolidated his position. He began to implement reforms to improve the lives of the people, winning praise from both the court and the public.

Niannian's time in the modern world is running out; she knows she will eventually have to return to her own time and space. Before leaving, she decides to help Pei Yunjing complete his reform project.

In modern times, Niannian's sudden disappearance caused Grandpa Fu great anxiety.

He searched everywhere, but still couldn't find any news of Niannian. Until one day, Niannian returned to the modern world, exhausted, and told Grandpa Fu about her experiences in ancient times.
