Under the flickering light, Mr. Xu stood in front of the door and thought for a while, then told Zhou Yan and others everything he saw.

Teacher Xu went out for business today, and he was busy until after eight o'clock in the evening.When going upstairs, he heard strange footsteps coming from upstairs, so he grabbed the handrail of the stairs and leaned over to take a look, and saw a vague black shadow running down from the tall building.

That black shadow didn't look right, Teacher Xu yelled, and the black shadow ran away.Because the floor where he was standing was too low, Mr. Xu couldn't see which floor the black shadow had gone to.When he reached the third floor, a room happened to close the door in front of him. He thought that the people living in it might have seen the shadow, so he went to the door of 305 and knocked.

Teacher Xu stood at the door and waited for a few minutes before someone who lived in 305 came over and opened the door.

The resident of 305 looks familiar. Knowing that the other party is a new teacher who has not yet joined the job, Teacher Xu asked him if he saw a black shadow. The resident of 305 said that he did not see the shadow, but heard the footsteps of the shadow. The shadow stopped when he reached the fourth floor, and did not come to the third floor.

Mr. Xu remembered very clearly that when he finished thanking him, there was a sudden sound of a heavy object falling to the ground in a bedroom in 305.The person living in 305 said that something he put on the bedside table probably dropped, and he closed the door hastily.

Suspecting that the people living in 305 were hiding something bad, Mr. Xu wanted to stay where he was and listen to what was going on inside. It happened that someone from the other side of the corridor opened the door and came out to look at him, so he stopped staying on the third floor and went to the fourth floor Back to his room.

Teacher Xu finished talking here, and everyone looked at Ning Luan in unison.

Ning Luan nodded and said in a low voice, "It's true. When I saw him, he was walking towards the stairs on the third floor. As for where he went and whether he returned, I don't know."

Teacher Xu looked at Ning Luan: "Are you the one who opened the door to look at me in the corridor on the other side of the third floor?"

Ning Luan had been with Zhou Yan and Lu Chenzhao for a long time, and he was much more courageous than when he went to Hongwa Village. He scratched his hair and looked at Teacher Xu with some expectation in his eyes: "Mr. Xu, if I answer For you, can I ask a question related to Lin Mingming?"

"No, he is the only one who can ask questions tonight." Teacher Xu shook his head, looked at Zhou Yan and said, "Sir, do you want to answer my question first, or continue to ask the second question?"

Zhou Yan stared blankly at Teacher Xu's face for a while, then said coldly, "Answer the question."

"Okay, my question is very simple. It is a math problem that all first-year students of Dao Elementary School will." Teacher Xu glanced at the crowd gathered at the gate of 405, "At eleven o'clock in the evening on December 12th, there was a Seven people knocked on the door of 27 and asked Teacher Xu a question, how many people were there in the corridor on the fourth floor when Teacher Xu walked out of the room?"

Teacher Xu's question sounds really simple at first glance, it's just a matter of counting how many people are in the corridor.But as long as you think about it a little bit, you will feel that the problem is not so simple.For example, is Teacher Xu who asked them a question a human being?

Realizing this, everyone's expressions were a little bit wrong.

This question is not simple at all, it is simply the most difficult question they have encountered these days.

The people standing behind Zhou Yan carefully looked at Teacher Xu, trying to distinguish whether he was a human being or something else.

Teacher Xu didn't care about everyone's gaze, and watched Zhou Yan gently, waiting for him to give an answer.

In the quiet corridor, Zhou Yan stood upright, reached into his coat pocket with his left hand, and knocked on the black box he put inside.

After a while, Zhou Yan raised his eyes and looked at Teacher Xu quietly. The red mole on his left earlobe was shining dimly in the dim light: "I have a question."

Teacher Xu: "Ask, but your time is running out."

Hearing that time was running out, the expression on Zhou Yan's face didn't change much, and he remained indifferent: "If I say I'm the only one, and then kill everyone else, will I be right or wrong?"

Even though everyone thought that Zhou Yan would not kill everyone else just to answer a question correctly, they were still taken aback by Zhou Yan, and they didn't recover for a while.

Teacher Xu glanced at Zhou Yan with a strange expression, and said, "The answer is how many people are standing in the corridor at the end."

He already knew what he wanted to know, Zhou Yan said coldly: "There are eight people in the corridor."

Teacher Xu kindly reminded: "Do you want to count again?"

Zhou Yan insisted: "Eight."

Teacher Xu couldn't bear it so much that he almost wrote on his face that your answer was wrong: "Are you really not going to change it?"

When Zhou Yan said that there were eight people, everyone felt that the answer might be wrong.

After listening to what Teacher Xu said, they felt that there was something wrong with Zhou Yan's answer. They all felt a little panicked. They wanted to persuade Zhou Yan, but they were afraid of being fooled by Teacher Xu.

Teacher Xu sighed and said regretfully, "I'm sorry, you got the wrong answer."

Everyone: "!!!"

Teacher Xu didn't lie to them!

Could it be that the correct answer is seven, and Teacher Xu is really not human?

Teacher Xu said again: "You can't ask me anymore. After you die, other people can ask me and Lin Mingming-related questions instead of you."

Hearing that Zhou Yan was about to die, the others were in a hurry.

Zhou Yan still had a calm face, but when Teacher Xu said that other people could ask questions on his behalf, he gave Teacher Xu a cold look.

Thick mist overflowed from the left pocket of Zhou Yan's coat, and disappeared in an instant.

Lu Chenzhao stood beside Zhou Yan in a long brown coat, his long black hair hung down his shoulders and behind him, shaking gently in the wind.

Lu Chenzhao glanced at Zhou Yan with a smile, and casually said to Teacher Xu: "I'm sorry, my captain got the answer right, and you are the one who was wrong."

Everyone: "???"

Can the answer be changed?

Boss Lu, is this going to cause trouble?

Teacher Xu's eyes moved back and forth between Lu Chenzhao and Zhou Yan, and after a while he said: "You are right, eight is the correct answer now."

Everyone: "..."

If you say change it, change it, Mr. Lu hasn't done anything yet.

Standing in the crowd, Chen Li whispered, "What's going on here, please understand."

"Teacher Xu said how many people stood in the corridor at the end, the answer is that number." Luo Nan thought for a while and said, "I guess the original answer was seven, but after Mr. Lu came out of the box, it would be eight. "

Chen Li said in a daze, "But Boss Lu is not a human being."

Luo Nan was also a little confused: "I don't know about that."

Zhou Yan turned his head and glanced at them: "Lu Chenzhao is human."

Chen Li: "Huh?"

Zhou Yan explained in a cold voice: "The person who gave us the pass said that there are a total of ten people who came to the experimental primary school, including Lu Chenzhao."

"No wonder Captain Zhou insisted that the answer is eight after listening to Mr. Xu's answer." Chang Minghao sighed, "The correct answer is eight is the best, in case eight is wrong, the correct answer is seven, as long as Mr. Lu comes out , the answer becomes eight."

Song Yu thought of a certain possibility, and shivered: "No, if Mr. Lu who is staying in the box has to be added, the correct answer is nine, and it will be useless even if Mr. Lu comes out. Still one less person."

Hearing what Song Yu said, Lu Chenzhao turned his head and said with a smile, "It doesn't matter, if one person dies, the answer will be eight."

Everyone: "..."

The aftermath of Zhou Yan saying that he wanted to kill all the others was still there, and everyone expressed that they were twice as frightened.

A few minutes passed in a blink of an eye, and Teacher Xu asked, "It's getting late, when will you ask me about Lin Mingming?"

Zhou Yan looked at Teacher Xu coolly: "Are you sure you still want me to ask a question?"

Teacher Xu said: "Of course, you must ask one every night. If you don't ask, you will die."

Zhou Yan was silent for a while.

When he spoke again, his voice was colder than the snow falling from the sky outside the window: "Stop pretending."

Teacher Xu was stunned: "What?"

Zhou Yan looked down at him: "The first question I asked you was about the missing child, about Lin Mingming."
