Through the towering windows, mottled light and shadows are cast, reflecting on the endless bookshelves. This temple of knowledge is the home of the young librarian Arya. She always shuttles through the ocean of books, as if she is talking to history.

That afternoon, she found a book that was particularly eye-catching. The mottled cover of the ancient book seemed to have never been touched by anyone, and the ancient words and patterns engraved on it seemed to be calling her. Arya carefully took the book off and wiped off the dust. A mysterious breath came to her face, making her heart beat faster.

Sitting in the corner of the library, Arya opened the ancient book and found that it recorded the legend of the "key of time". This key can control time and open the portal of time and space, but it can also cause unpredictable disasters. The book also mentions some clues to find the key, many of which coincide with the legends of Arya's family - especially a mysterious staff that has been passed down from generation to generation in the family.

When Arya took the staff out of her bag and placed it on the table, something strange happened. The runes on the surface of the staff began to glow slightly, echoing the runes in the ancient book. The light blue light drew an ancient star map in the air, with some vague locations marked on it, which seemed to be clues to the location of the Key of Time.

Arya (whispering in shock): "It... is real!"

At this time, her friend and colleague Leia came over and witnessed this scene.

Leia (stunned): "Arya, how did you do it? This staff actually... responded to this book?"

Arya: "I don't know either. I only know that it is a family inheritance, and my grandfather once said it was important. But this seems to be far beyond my imagination..."

Leia's expression changed from shock to worry. She gently picked up the staff, but felt a burst of warmth, as if the object had its own life.

Leah (seriously): "Maybe the Key of Time is not just a legend. If the power of the staff is real, then your family may have a deeper connection with this legend."

Although Leah is worried about the possible dangers, Arya's intuition and family memories are urging her to take action. She said firmly:

Arya: "No matter what the risk, I must go find it. If it really exists, its power may save or destroy the world. We can't ignore it."

Liya hesitated for a moment, and finally solemnly shook Arya's hand: "If you really want to go, I will support you. But remember, no matter what happens, this will always be your home."

Before preparing to set off, Arya studied the connection between the ancient book and the staff. In an accidental attempt, she pointed the staff at an ancient rune mentioned in the book. The top of the staff emitted a strong light, and a dynamic map appeared in the air. This map is clearer than the previous star map and shows a path to the first ruins.

Arya understands that the staff is not only a family inheritance, it is also the key tool for her to unlock the secret of the Key of Time.

Arya (muttering to herself): "Perhaps, it has been waiting for this day."

On the day of departure, Arya held the staff tightly in her hand. Just as she was about to leave, a mysterious man in black emerged from the shadows of the library. His eyes were deep and his voice was low:

Man in black: "The power of the Key of Time is far beyond your imagination. Once you embark on this path, you can never turn back."

Arya looked directly at the other party. Although she felt uneasy in her heart, she was unwilling to show hesitation:

Arya: "No matter how many unknowns there are ahead, I will find it and protect the peace of this world."

The man in black was silent for a moment, raised a meaningful smile at the corner of his mouth, and disappeared in the shadows in an instant. His appearance cast a mysterious shadow on Arya's journey.

Arya's figure disappeared in the dusk outside the library. She didn't know what kind of challenge was waiting for her, but her belief never wavered. The clues in the ancient books, the family's staff, and the warnings of the man in black all indicate that this will be a journey that will change fate.

The first use of the staff not only verifies the authenticity of the legend of the Key of Time, but also lays the groundwork for the next adventure: How can Arya further master the power of the staff? Who is the man in black? Is he an enemy or a friend? Everything has just begun...
