With the sound of heavy footsteps, gradually approaching, Zhang Xing's heart seemed to rise to his throat.

But the monster began to look for it one by one. When the monster walked to the classroom where Zhang Xing was, it suddenly let out a painful roar, and it retreated uncontrollably.

until they entered the iron door at the end of the hallway.

After a few minutes, someone gently patted Zhang Xing's shoulder, "Okay, it's okay." ”

Zhang Xing looked up and found a slim girl squatting in front of him. Her face was tight, but her face turned pale with fear.

"Thank you." Zhang Xing said lightly.

"My name is Liang Li, and I am Wu Kun's girlfriend." The girl replied and looked out the window.

"By the way, what about others?" The girl said without looking back.

"I met him when I was upstairs, but I can't find him now." Zhang Xing told the girl truthfully.

After listening to Zhang Xing's words, the girl's expression became a little cloudy, "It's good that the bastard is dead." ”

"Aren't you his girlfriend? Why do you still want him to die? Zhang Xing asked puzzled.

"Hmph, that guy is a pervert." After the girl finished speaking, she twisted her head to the side and stopped talking.

After a while, she said, "Did you find the lockbox?" ”

Zhang Xing glanced at her and shook his head in confusion.

"Let's go meet up with the others first, and then find that lockbox!" With that, she got up and walked out of the classroom.

Zhang Xing glanced at her and got up and walked out.

They didn't stop all the way to the rooftop.

Liang Li was just about to knock on the door when she heard a deep voice from the door: "Who is it?" ”

Liang Li glanced at Zhang Xing and said, "Liang Li, there is still one last contestant. ”

As soon as she finished speaking, the "click" door opened. Liang Li walked straight in. Zhang Xing walked in without too much hesitation.

When Zhang Xing walked up to the rooftop, he found that an old man in a white coat not far away was sitting on the ground studying two password boxes.

And by the door stood a tall man wearing a camouflage military uniform and a dagger pinned to his waist, and he looked at Zhang Xing with the eyes like a beast staring at its prey.

Liang Li took out a lockbox from her arms, put it on the ground, looked at the old man and said, "This is the third one." ”

At this time, the man in military uniform leaned against the door and said coldly, "It's useless to have boxes, each box seems to have a corresponding password." ”

"How do you know?" Zhang Xing looked at him and asked.

"Each box is about the same length, but there are four very different numbers, and it is estimated that you will have to try them until next year.

So I'm guessing there must be a hint of a password here. The man in military uniform said lightly.

"You're amazing!" Zhang Xing looked at him and said adoringly.

"Heh, I had password training when I was a soldier. So that's a small thing to me.

By the way, my name is Yan Kuan, and the old man is a physics professor surnamed Zhou. The man in military uniform said after a large number of punishments.

"My name is Zhang Xing!" He scratched his head in embarrassment.

"Why are you hiding here, if that monster finds out, it will be difficult for you to run!" Zhang Xing sat on the side and said.

"It's very simple, it's a game, the monster with regularity, the first time it appears on the third floor, then it disappears on the second floor, the second time it appears on the second floor, it disappears on the first floor.

But it didn't happen here at any time.

So I'm guessing it should be safe here. The man in military uniform swore an oath.

Hearing his words, Zhang Xing suddenly got up and asked, "Where did you get your boxes from?" ”

At this time, the old man who had not spoken said at this time, "One is in the cubicle of the classroom desk on the third floor, the other is under a floor tile on the first floor, and the last is in front of the door of the basement. ”

The old man's voice was hoarse, but his eyes were full of energy.

Zhang Xing suddenly sounded the words that Wu Kun shouted, so he said, "I know where the password box on the second layer is." ”

"Where?" The man in military uniform asked coldly

Zhang Xing shook his head slightly, "I'm sorry, I can't tell you." ”

After hearing Zhang Xing's words, everyone frowned, but soon Liang Li said, "Forget it, I'll go with him to get it, you can continue to crack the password box here!" ”

The man in military uniform wanted to say something, but the old man said, "Do as he says." ”

Zhang Xing smiled lightly and said, "Thank you!" Then he left the rooftop. Liang Li also followed his pace and left.

When they reached the second floor, Zhang Xing suddenly stopped and said, "You are smarter than I thought. ”

Liang Li sneered and said, "In your eyes, are women all stupid? ”

Zhang Xing was noncommittal about this, and then Zhang Xing walked into the classroom under Liang Li's angry gaze.

"Hey, do you really know where the box is?" Liang Li said angrily.

Zhang Xing nodded, then carefully looked at each painting in the classroom, and finally made a discovery at the last pair.

He gently took the drawing off, and when it was turned upside down, it was a map with coordinates on it.

He compares them one by one according to the position of the coordinates, and then compares them to 72; At 50 o'clock, Zhang Xing's eyes showed a hint of surprise.

He looked up at Liang Li, "I found it." Then he walked to the end of the classroom and picked up a hammer and threw it at the wall.

After a dozen taps, the wall was finally shattered, and a lockbox lay quietly inside.

Liang Li looked at Zhang Xing, found the password box, walked up to him and said, "I really made you blind!" ”

Zhang Xing glanced at her, "This is thanks to your boyfriend, he found this coordinate." ”

"Are we going back?" Liang Li asked softly.

"Of course not, just let those two self-righteous guys fend for themselves." Zhang Xing said coldly.

"How can you be sure that the monster will appear on the rooftop this time?" Liang Li asked strangely.

"Because it's been everywhere else. On the first floor, the monster has already found us, but it's time, so next time it will be somewhere it hasn't been found. Zhang Xing said softly.

"The box?" Liang Li asked.

"The monster's target is just us, the box won't move." Zhang Xing calmly analyzed.

"You're amazing! So where do we go now? Liang Li asked.

"Go to the basement and find the last box." With that, they walked out of the classroom.

Soon, the monster reappeared, and this time as Zhang Xing expected. The monster appeared on the rooftop, and in just a moment, the two were discovered by the monster.

With a roar, it rushed towards the man in military uniform......
