In the public library in the city center, Luo Zhi sat in the middle of the stacks, twisting his sore neck and looking at his watch. 2:12 p.m. "Time flies." The smell of lunch still lingers in my mouth. Luo Zhi smacked his lips and looked around a few times. The fiery sun is scorching the city in the afternoon. The vehicles on the road outside were moving lazily, and Luo Zhi was thinking about something while resting on the table, and fell asleep unconsciously.

I don't know when, a noise woke him up. The sound is far away and messy. Luo Zhi raised his head in a daze, and he was the only one around.

"Is the library about to close? Who's arguing? ”

The tall bookshelves blocked his view, and Luo Zhi stood up and looked at his watch. At two o'clock, the damn watch stopped. He turned his head, looked around, and suddenly felt that something was not quite right. Through the tall floor-to-ceiling glass, the scene outside is strange. There was not a single pedestrian on the wide street, and the vehicles were all parked on the road, motionless. The library is located in the middle of the city, and the streets are usually full of traffic, but today they all stopped as if they were enchanted, and there was no sound.

Luo Zhi felt nervous, "Did you have a traffic accident?" "The computer in the distance is still on, and the screen is bright. Luo Zhi walked to the computer, the time was displayed at 3:04, and it was still far from closing, why was there no one? The administrator's office chair is also empty. What about people?

Luo Zhi walked towards the place where the noise came from, and the sound came from the electronic reading room at the end of the corridor. A frosted glass door was hidden. Luo Zhi pushed open the door, and the scene inside surprised him. Not a single one. Usually this is the busiest place in the museum. Half of the computers were still on, the sound was coming from the computer in the administrator's seat, the headphones had fallen off for some reason, and the loud background sound of the online movies in the library came from the speakers. The sight suddenly became familiar. Luo Zhimeng turned his head, and the library behind him was empty. The noisy sound of movies echoed in the empty room, and Luo Zhi finally realized that he was the only one on the entire floor.

He shuddered. Is this some kind of prank? Probably not. Few people in the city knew him, and no one would make such a big joke on him. Could it be an air raid siren? But why didn't anyone wake him up? Luo Zhi instinctively leaned towards a wall, his movements light and fast. His heart was beating violently, and he couldn't help but gasp for air. He looked around quickly. Nothing has changed, except for people. The books on the shelves are neatly lined up there. Suddenly, he was afraid to see a pair of eyes or something in the depths of the bookshelf. The images from the horror movie flooded into his head, and he quickly looked away.

It was time to go downstairs, he was anxious to know what had happened. He walked slowly along the wall to the exit of the stack. The building is a hollow structure, and the high lobby on the first floor can be seen from the corridor outside the stacks. The escalators on both sides were still moving, and unsurprisingly, no one was there. The huge floor-to-ceiling glass windows let in gray-green sunlight, and the surroundings were quiet. Luo Zhi felt his legs go limp, and his scalp was numb for a while. His senses were sharper than ever, and he could hear the sound of dripping water in the bathroom. He wanted to ask aloud if anyone was there, but he couldn't open his mouth in fear. He knew that if he shouted loudly, the echo from the hall would startle him.

Suddenly, there was a faint sound of footsteps in the exhibition hall in the basement of the library, followed by a figure flashing through the gap in the escalator. Someone! Luo Zhi was sure that it was a human figure, but he didn't dare to shout. Who is this? What kind of dangerous molecules? Or is it someone who's scared enough like yourself? Luo Zhimeng's spirit, no matter what, he couldn't stay upstairs, he had to find a way to go outside. Luo Zhi's head was spinning quickly, elevators and escalators must not go, what should I do if there is danger in the stairwell? Luo Zhi slowly walked back to the library and found a metal bookend on the desk of the doorkeeper, which was the best weapon he could find now. Luo Zhi knew that there was an art knife for cutting rough-edged paper books in the ancient books department upstairs, but he didn't want to go upstairs even if he was killed, not to mention that the thing cut paper was okay, and it was not necessarily easy to use in case of danger. Luo Zhi thought of the taekwondo he learned in his sophomore year, and he used to be complacent. Now he knows he's a three-legged cat. "At that time, it would be nice to work a little hard." Luo Zhi secretly regretted it, tiptoed along the wall to the door of the stairwell, staring at the gap in the escalator from time to time. There was no movement in the exhibition hall, and the man must have gone somewhere else.

Luo Zhi held his breath, lifted the bookend, and slowly rubbed into the stairwell. Suddenly, a man from behind the door rushed towards him. The two looked at each other and couldn't help but scream loudly at the same time.
