One of Zhang Zhen's ghost stories: On a barren mountain, there was a temple that had been abandoned for a long time. Legend has it that a famous master once lived here, but he mysteriously disappeared and the temple has been empty ever since. Recently, there was a rumor that a mysterious ghost lived in the temple. He always appeared at night and asked people for money and treasures. Many people went to the temple to explore but found nothing. Until one day, a young man named Zhang Zhen came to this barren mountain. He was an experienced explorer who had explored mysterious places many times. He had heard rumors about the temple and decided to explore it. Zhang Zhen discovered an ancient tower in the temple. He went deep into the tower and found that there was nothing but darkness inside. He decided to leave the tower and continue exploring the temple. Suddenly, he heard a strange sound as if someone was calling his name. He approached the source of the sound and found a gray cat lying there. This cat was very mysterious. It seemed to know Zhang Zhen's purpose of coming and began to ask him for money and treasures. Zhang Zhen felt extremely disgusted, so he decided to escape from the temple. As he left, he heard a deep sigh, as if the mysterious mage was saying goodbye to him. Zhang Zhen realized that he might have met the mysterious ghost. He was terrified, but he didn't give up. He decided to find a way to unravel the secret of the gray cat. After some exploration, Zhang Zhen finally found a mysterious box. He took the box back to the temple and tried to show the secret of the box to others. However, the box did not work. The gray cat did not appear, nor did it ask for any money or treasures from Zhang Zhen. Zhang Zhen realized that this cat was actually a civet cat. It knew its fate.
