Silver Obsidian Bracelet [Dragon Head]: Energy Guardian of the Mysterious Night Sky

There is a girl named Amei in the town. She has a special fascination with the night sky since she was a child. Whenever night falls, she would sit on the roof alone, looking up at the starry sky, as if she could find the belonging of her soul from it.
Amei's grandmother once gave her a silver obsidian bracelet, telling her that this bracelet could protect her and let her find her way in the dark. Amei has always regarded this bracelet as a treasure and never left it.
One night, a strange thing happened in the town. Many people began to have nightmares and could not sleep at night. The oldest man in the village said that this was evil and needed to be suppressed with holy objects.
After hearing this, Amei felt a little uneasy. She remembered her grandmother's words and took out the silver obsidian bracelet to look at it carefully. The silver obsidian on the bracelet sparkled in the moonlight, as if it contained infinite power.
Amei decided to use the silver obsidian to help the villagers. She came to the ancient well in the town, raised the silver obsidian high, and aimed it at the wellhead. In an instant, the silver obsidian shone brightly, illuminating the entire bottom of the well. A shadow emerged from the well water. It was a huge black cat, and its eyes flashed with strange red light.
The black cat roared and pounced on Amei. Amei was not in a hurry. She raised the silver obsidian above her head, and a silver light shot at the black cat. The black cat screamed and turned into a wisp of green smoke and dissipated.
Since then, the town has returned to peace. The villagers praised Amei as their patron saint. Amei knew that all this was thanks to her silver obsidian bracelet.
Many years later, Amei became the guardian of the town. Whenever night fell, she would sit on the roof, holding the silver obsidian in her hand, guarding the town and everyone's safety.
