Song Ze went to the school cafeteria for a simple dinner. remembered that Zhou Jie said that after Bai Yuhan's death, there was a voice in the laboratory, and the voice in the laboratory should be related to Bai Yuhan. If there really are ghosts in the world, does she have something to ask him for help?

Thinking of this, Song Ze stopped preparing to go to the teaching and research department to prepare for classes. Seeing that it was already dark, he picked up his mobile phone and made a call to Zhou Jie.

After Zhou Jie received the call, he quickly rushed over and saw Song Ze waiting for him at the intersection.

"Did you come to me for the sake of lab sound?"

"Yes. Now only I can hear the voice, I wonder if it's because I'm too sorry for Bai Yuhan's death and hallucinate, so I'm looking for you to confirm. Song Ze said while walking with Zhou Jie.

The two men walked slowly along the school road in the direction of the laboratory. Just after dinner, the campus was full of students. When they saw Professor Song, they all came over to say hello.

"Hello, Professor Song. "Professor Song, you're going to the lab again. ”“......”

"I find you very popular with students. It's not easy for you to have so many students like you with a straight face every day. It's handsome, and everyone loves it."

"The most important thing in school is to teach and educate people! As long as you can keep your heart, students will respect you, and it has nothing to do with your appearance. Song Ze indifferently patted the book in his hand.

There are so many old professors in the school who keep their hearts, teach and educate people, and are highly respected. I haven't seen the students so enthusiastic, it's not because of your face, Zhou Jie slandered in his heart.

After dinner, some students have to study on their own in the evening to prepare for tomorrow's lessons, and some find a place to play. When the two of them arrived in the experimental building, it was quiet, there were no students, and even the sensor lights in the corridor were black.

"I found your school's laboratory building to be quite scary at night. It was empty. Not even a night light. Such a long, deep corridor still sounds empty, empty, empty when you walk. Don't you feel scared when you're here alone at night?"

"There's nothing to be afraid of. It's also this corridor during the day, and it's still this corridor at night, but there's a difference between light and no light," Song Ze said as he opened the door of the laboratory with the key and turned on the light on the roof of the room.

"The scary thing is that there is no light. I really admire you more and more now, the ignorant are fearless. ”

Zhou Jie entered the laboratory, looked at the laboratory full of books and various experimental instruments, and curiously picked up a few books.

"On the Origin of the Universe", "Is the Universe One?", "Is There Extraterrestrial Life in the Universe". Song Ze opened the book and looked at it a few times, then put it back.

"I don't understand what this is all about, except for this extraterrestrial life. Now think about how the hell I became friends with you, it's unbelievable!"

Song Ze was preparing a lesson plan for tomorrow's class. Zhou Jie rummaged around and looked around in the laboratory, and sometimes talked to Song Ze. In the end, I was really bored, so I picked up the book "Is There Extraterrestrial Life in the Universe" that I still didn't know much about, and read it.

The night was getting deeper and deeper, and the noise and playing ball from the playground outside the laboratory gradually disappeared. The bustling voices of people on the road outside the window were no longer audible. The lights of the school's teaching buildings and dormitories were turned off one after another.

It's getting quieter and quieter outside the window. The entire school was immersed in darkness, and it seemed that only this laboratory was still lit. There was no sound in the quiet campus late at night, and it was so quiet that the sound of Song Ze's two people breathing could be heard in the laboratory, whirring and ......

Suddenly, there was a hollow, empty sound in the hallway. The sound of empty footsteps was getting closer and closer, and suddenly there was a soft knock on the door. Zhou Jie stood up abruptly, staring nervously at the door of the laboratory.

"Teacher Song, is that you?" "Teacher Song, is it you?" A low call sounded outside the door. Song Ze put down the book in his hand, walked over and slammed open the door of the laboratory. I saw a person standing outside the door, with a hideous face, and when he heard the sound of the door open, he put on an attacking posture.

Song Ze took a closer look, and the person who came was holding a flashlight in his left hand and wearing school work clothes, which turned out to be a security guard studying to check the night at night. The security guard saw that it was Teacher Song who opened the door, relaxed down, and touched the little heart on his chest.

"Whew...... It turned out to be Mr. Song, and it scared me to death. Teacher Song, are you still busy? I saw that the lights were still on, so I came over to take a look. Something like that happened here before, and some students said something was wrong here, and I saw the lights on and thought it was ...... The lights were on all night the night before it happened!"

Song Ze nodded and said, "I still have something to do, so I haven't gone back yet." Nothing to do here, don't worry. ”

The security guard looked around the lab and found nothing out of the ordinary.

"Teacher Song, you're done, remember to turn off the lights before leaving," said he took the flashlight and left.

Song Ze closed the door, looked at Zhou Jie, who was standing there, and said suspiciously:

"It's the security guard who patrols the school at night, haven't you always cultivated the Tao, why are you so daring? ”

"I'll just say that the corridor of your laboratory building is very scary, and the sound of walking is really scary. Especially in the dead of night, it can scare people to death. Cultivators know more, and naturally have a sense of fear, unlike those who don't know it.

Besides, your security guards are a bit weird. When I heard the knock on the door, my voice was low and trembling, and I wanted to scare people to death. ”

The footsteps of the security guards faded away until they could no longer be heard. Outside the window, in the darkness, the shadows of the trees swayed. The window seemed to be blown by the wind outside the window, making a soft "creaking" sound.

"Teacher Song, Teacher Song......"

Song Ze listened attentively, and seemed to hear someone faintly calling him again. glanced at Zhou Jie, and his expression was not the way he teased him just now, but became a little dignified. His left and right hands kept touching his arm and nodded to him.

Song Ze saw Zhou Jie's appearance and turned off the light next to him. The room darkened suddenly, and Zhou Jie let out an "ah" sound, and it was quiet again. Song Ze walked to the window in the dark and looked at the big tree outside the window.

It was late at night, but the street lights were still on. There should be a slight light outside the window, but now I feel that the window is not as bright as usual. The light from the street lamp seemed to be blocked by something, and it looked dark outside the window.

Song Ze followed the wall again and slowly touched the place where Zhou Jie was standing. stood behind Zhou Jie, lay on Zhou Jie's shoulder, and whispered to him softly:

"Do you hear me?"

Zhou Jie screamed "ah" and rushed forward. I stumbled to the door of the laboratory, felt the switch on the wall, and pressed it hard. The lights in the room turned on all of a sudden, and when he turned around, he saw Song Ze looking at him in surprise.

Zhou Jie saw Song Ze standing where he had just stood and knew that he had misunderstood just now. Some said angrily:

"Aze, you almost scared me to death just now, do you know?Why did you suddenly turn off the lights and suddenly run to me and whisper?"

"I heard a voice just now, and I saw you nodding again. So I thought I turned off the lights and might find something in the dark. The whisper is because I'm afraid that the sound will be too loud and will scare the one who makes the sound. Why did you turn on the lights all of a sudden, it must have scared her away. Song Ze's face was both innocent and a little surprised.

"Aze, you will be my father in the future. You're afraid to scare her, you're not afraid to scare me. ”

Zhou Jie completely convinced Song Ze. He has never seen such a person in his life, and when people encounter this kind of thing, they are all worried and afraid, but he is afraid of scaring that.

Could it be that those who engage in natural sciences are like this...... Fortunately, he only has one scientist friend in his life, Song Ze...... He really can't bear it anymore......
