When Li Bing and Zhao Wan'er walked out of the police station, it was already dark. At the beginning of the lanterns, a full moon is still clearly visible under the strong light pollution above the noisy city.

"Tomorrow is the Mid-Autumn Festival, right?" Li Bing looked at Zhao Wan'er with a smile: "I've been in the police station for so long, I'm really hungry." Wan'er, why don't I invite you to the tea house for dinner now, of course, Mid-Autumn Festival mooncakes are indispensable. ”

Before Zhao Wan'er could agree, her mobile phone rang, and it turned out to be Zhang Lili calling to wish her daughter a happy Mid-Autumn Festival. Zhao Wan'er rejected her mother's request for her to rush back to Shanghai for the holiday, and just hung up, she received a call from Wang Liping. Zhao Wan'er also rejected Wang Liping's courteous invitation, telling him that she didn't have the heart to celebrate the festival before she got an answer to many strange things. Wang Liping said stupidly: "Wan'er, then I wish you a happy Mid-Autumn Festival!" By the way, I have already helped you drive your car to the door of your hotel, and the car keys are at the main desk, and you can go and collect them yourself. ”

After Zhao Wan'er hung up the phone, she found that she had unconsciously followed Li Bing to a small but cozy tea bar.

The two were in the tea bar, chatting about the afternoon's affairs in the police station, and it was funny to think that the captain of the criminal police had widened his eyes after listening to their narration, and he suspected that the two of them had mental problems. And the female corpse, after the technical appraisal was indeed not a modern person, the criminal police team also made a conclusion that it was not a homicide, and called the Cultural Relics Administration to pull the female corpse for research.

Li Bing thought of Wang Jie, so he called Wang Jie and greeted her with a happy Mid-Autumn Festival. Wang Jie also wished Li Bing and Zhao Wan'er a happy holiday on the other end of the phone, and told Li Bing that she had now been settled. The bronze mirror that caused her trouble, she decided not to want it, gave it to Li Bing for research, and asked someone to send it to Li Bing's residence early tomorrow morning. Before Li Bing could excuse herself, Wang Jie had already hung up the phone.

Zhao Wan'er took out Shi Liya's business card from her bag and dialed her number.

On the phone, Shi Liya told Zhao Wan'er that the appointment was originally scheduled to be 8 o'clock, but when she finally contacted Zhang Yuanshan, she knew that he was now in Hangzhou and was about to rush back. After Shi Liya asked Zhao Wan'er's address, she told Zhao Wan'er to let her wait, and she would never break her promise and would definitely meet with Zhang Yuanshan tonight.

The two of them saw that it was still early and leisurely drank their drinks. Li Bing suddenly smiled and said, "Look, I'm so busy that I forgot about the teacher." ”

Just as Li Bing was about to call Professor Zhang's phone, the mobile phone suddenly rang, and Li Bing looked down and saw that it was Professor Zhang's call. Li Bing hurriedly pressed the call button: "Teacher, I wish you a happy Mid-Autumn Festival!" There are so many things today, I almost forgot to say hello to your old man, I'm so sorry! ”

"Li Bing", Professor Zhang's voice on the other end of the phone was very urgent: "Where are you now?" I've been studying archaeology all my life, but last night I encountered a lot of strange things, and I couldn't figure it out, and I wanted to discuss it with you. ”

Li Bing's eyes widened in surprise, he knew in his heart that Professor Zhang said that he encountered many strange things last night, and it must be related to his identification of the bronze mirror last night.

The two drank milk tea anxiously, and it didn't take long for Professor Zhang to appear in front of them.

Professor Zhang's face turned pale, he slowly opened the leather bag he was carrying, took out a notebook from it, and handed it to Li Bing: "Li Bing, I feel that something seems to be going to happen to me, this diary is written by my teacher, you bring it with you, it may help you." ”

Li Bing asked Professor Zhang in surprise what had happened, and Professor Zhang took a few sips of tea, and the old man stabilized his mood and told Li about the strange things he had seen last night.

It turned out that yesterday, when Li Bing and the others left, Professor Zhang was so excited that he didn't bother to eat dinner, so he began to study the bronze mirror carefully.

With his profound knowledge and years of experience, Professor Zhang used various instruments to determine that this bronze mirror was not an imitation, but was truly from the court of the early Ming Dynasty. After consulting a lot of information to no avail, he was very anxious, and then he thought of the archaeological diary left to him by his teacher before his death, and finally found the folklore about the origin of the bronze mirror. So, Professor Zhang excitedly immediately dialed Li Bing's phone and told Li Bing everything about the bronze mirror on the phone.

Just when Li Bing and the others were silent after hearing this bizarre story, Professor Zhang was shouting Li Bing on the phone, when he suddenly heard the footsteps of someone walking in the corridor of the laboratory building. Professor Zhang felt very strange, this experimental building, usually few people come, not to mention that it is already late at night, who could it be? So, Professor Zhang hung up the phone, pushed open the door of the laboratory, and walked into the corridor to see what was going on.

When Professor Zhang walked out of the door, he found that the corridor was empty, muttered to himself, and walked back to the laboratory.

As he walked back to the lab, the lights suddenly went out, and only the hallway was still lit by street lights. Professor Zhang had no choice but to pick up an emergency flashlight hanging on the wall of the laboratory and prepare to leave the laboratory building and go home.

When he walked in the corridor, the street lamps that had just been fine suddenly began to flicker brightly and dimly, and Professor Zhang said to himself: "I have to talk to the department leaders tomorrow, maybe the lines here will be maintained." ”

Suddenly, he was stunned, he had never believed in ghosts and gods, and a cold sweat broke out on his back, and he seemed to feel a gust of wind blowing gently past him just now, although the wind was weak, but it made him feel a clear cold air, and he seemed to feel a pair of eyes staring at his back.

Professor Zhang calmed down and slowly turned around, only to find that there was nothing, and the street lights that were still flashing just now seemed to have returned to normal.

Professor Zhang shook his head, blaming himself for probably hearing Li Bing say that this bronze mirror was strange, and he was unconsciously influenced by Li Bing, so he had such a strange feeling.

When he walked to the turn of the stairs, he clearly heard the sound of "dong, dong" on the stairs, and Professor Zhang's scalp suddenly went numb, and he gritted his teeth and trotted all the way to the staircase to see what was going on.

When he came to the staircase on the third floor, his heart calmed down a little, it turned out that it was a volleyball rolling down from the third floor to the second floor, and it kept bouncing off the stairs and made that creepy sound.

Professor Zhang just breathed a sigh of relief, and suddenly thought of something, and his hairs stood on end even more than just now. It turned out that at the end of the corridor on the third floor of this experimental building, although you could see the playground outside, it was all sealed with glass, and there was no one else in the entire experimental building, and all the rooms were closed, so where did this volleyball come from? There is no wind in the corridor, how does this volleyball roll to the staircase on its own?

Although Professor Zhang was scared, he didn't listen to his own steps, and involuntarily followed the volleyball forward.

The volleyball didn't seem to stop, and continued to jump and move forward in the corridor on the second floor, although Professor Zhang complained in his heart, this phenomenon that obviously did not conform to the principles of mechanics made him begin to wonder if there were really ghosts in this world, but he still followed the volleyball.

Walking to the end of the corridor, the volleyball was inexplicably jumping upwards in the corridor at the other end. Professor Zhang was so frightened that his throat seemed to be blocked by something, and he wanted to scream but couldn't.

Back on the third floor, the volleyball jumped into a women's toilet that was hardly used. On the third floor of this building, there is only one laboratory for Professor Zhang, and at most Li Bing and two other graduate students come to study with him, but Professor Zhang's three students are all men, so the women's toilet is basically deserted and unused.

When he arrived at the door of the women's bathroom, Professor Zhang hesitated, the sound of the volleyball beating had disappeared, but there seemed to be a young woman sobbing softly in his ears.

Professor Zhang couldn't help but walk into the women's bathroom, only to see a rusty water tap in the washroom constantly flowing rusty water into the basin.

The good habit he usually develops makes Professor Zhang subconsciously step forward and turn off the water tap. When he turned off the halter, he was surprised to find that although the lid in the sink had long since fallen into disrepair, the water did not fall, and almost filled the entire basin.

Professor Zhang looked at the washbasin and was surprised to find that the rusty water that had been contained in it seemed to be slowly turning bright red in color, and it seemed to be slowly rotating as if it had come to life.

"Blood," Professor Zhang screamed in his heart, but his own ears clearly told him that he couldn't scream in his throat.

At this time, there seemed to be some movement in the women's toilet, and when he listened carefully, it was clear that it was a young woman's voice humming the Huangmei minor tune of Anhui.

Following the voice, Professor Zhang staggered to the fourth small door, and the sound seemed to come from inside.
