"Excuse me, what do you mean by 'replacement'?" Shi Yuan asked.

There was no inaudible rise or fall in his tone.

"'Replacement' means switching places with this person and enduring the subsequent torture and death. If he chooses to replace, he can do so now, or at the moment he dies after being tortured. The demon made an ethereal, cold sound.

Looking at Teacher Yan, who couldn't stop struggling and shouting, Shi Yuan hesitated.

According to the rules, if you want to save him, you must choose one of these six people to replace him.

If you want to get clues to the next step, you have to kill him.

The meaning of "substitution" has been made clear, and it refers to torture and death.

It is impossible for Shi Yuan to let someone else replace Teacher Yan.

Of these six people, the only one who could possibly replace Teacher Yan was himself, because he had the number of times he saved his life.

Even if he dies for Teacher Yan once, there are still many chances to live.

If he is not replaced, Teacher Yan will definitely die.

Just now, the evil ghost has shown that if he doesn't want to be tortured, he can also replace him at the moment of death, so that as long as he consumes a life-saving number of times, he can save Teacher Yan. It's just that Mr. Yan has to endure some torture similar to torture, but it is much better than death.

The reason why Shi Yuan hesitated, in addition to the preciousness of the number of life-saving times, there was another important reason.

This teacher Yan is the only teacher in the school who doesn't like him.

Shiyuan's IQ is much higher than that of the vast majority of students, and he has always been able to easily maintain top grades in learning, and he is the most appreciated and valued student by all teachers.

Except for this Teacher Yan.

As for the reason, it's also very simple.

Other students will express their feelings on important days such as Teacher's Day, Spring Festival, and Mid-Autumn Festival. Only Shi Yuan, as if he didn't know about the existence of these festivals, never even said "Happy Holidays" to him.

Of course, Shi Yuan was not specifically targeting him. For other teachers, he just greets when he thinks of it, and if he can't remember it, he won't say it.

However, other teachers never cared, only Teacher Yan always held a grudge.

In this regard, Shi Yuan naturally had already noticed it. After realizing it, of course, he was even more reluctant to deal with him.

Shi Yuan always felt that this Teacher Yan was very problematic, and it was not just a problem of a bad attitude towards him.

There are a few girls in their class, as well as a few girls in the neighboring classes where Teacher Yan is in charge of math classes, and every time they see him, they are submissive, and some of them turn pale when they see him.

The teacher is far from being an eventful person, everyone comes here to learn, if you really encounter something, you can find your parents or report to the school. Shi Yuan didn't meddle in anything.

What made Shi Yuan completely disappointed in this Teacher Yan happened three months ago.

There is a quiet and thin girl in Shi Yuan's class, named Hui Qianlan, who always speaks in a voice as small as a mosquito, and blushes every time she talks to Shi Yuan.

She has always been very quiet in class, no one has ever seen her make a loud noise, no matter in class or class, she always reads and studies quietly.

is such a girl, but one day suddenly absent from school for no reason.

Several female classmates who had a good relationship with her remembered that the day before, there seemed to be some bruises on her face and neck.

The next day, news spread in the school that Hui Qianlan committed suicide and left a suicide note.

The suicide note said that she could no longer endure the daily mental torture, and that math class was like hell for her.

Everyone thought that she chose to commit suicide because she was under pressure to study and high school math was too difficult.

However, a few days later, a piece of gossip reached everyone's ears.

The so-called "mental torture" does not come from mathematical knowledge, but from mathematical teachers.

Finally, in a math class, a boy who liked Hui Qianlan couldn't help but ask loudly: "Teacher, Hui Qianlan committed suicide, aren't you sad because of the student's death?" ”

At that time, Mr. Yan was writing formulas on the blackboard. Hearing the boy's words, he turned around and said with great displeasure: "Everyone will encounter countless difficulties in their lives, and when they encounter such a little difficulty, they can't bear it anymore, so they commit suicide, even if they live, they won't be able to become great things in the future!" ”

The boy felt a strong burst of anger and continued to shout: "But I heard that Hui Qianlan committed suicide because of you, Teacher Yan!" Are you bullying her? ”

"I bullied her? Joke! Teacher Yan dropped the chalk in her hand, "She has a problem herself, and she blames me?" Don't look at her as introverted, in fact, she has a lot of flowers and intestines in her stomach! But now there is no proof of death, and I can't say more, believe it or not! ”

Hearing Teacher Yan's words, whether they were close to Hui Qianlan or distant, the students felt a burst of anger.

However, this matter was talked about for a few days, and no one mentioned it again, as if Hui Qianlan had never existed, and the math class had returned to calm.

That incident, Shi Yuan has always felt strange.

In room 724, Mr. Yan's screams echoed for a long time, and there was no other sound.

Suddenly, the demon spoke again, "If you find it difficult to choose, you can take a look at this first." ”

After speaking, countless black and white points of light suddenly began to appear on the snow-white wall on the right side of the room, like snowflakes on TV.

Then, a picture is displayed.

For some reason, the image appears to have a blood-red hue, as if it was shot through a blood-stained camera lens.

The picture shows Teacher Yan's office, but at this moment, he is standing in front of a girl.

"Hui Qianlan, you must study hard, so that you can be successful."

There was nothing wrong with that, but his hand was on her shoulder.

Hui Qianlan shrank in the corner, her face full of big teardrops.

A waterfall of blood suddenly gushed down from above, and then the picture changed.

At noon, Hui Qianlan was lying on her desk for a morning break, her head covered with her own coat.

Suddenly, Teacher Yan walked up to her, with an inexplicable smile on her face, and lifted her coat while singing, "Lift your hijab!" ”

Hui Qianlan was so frightened that she trembled, and looked up suddenly, but what she saw was the face of Teacher Yan, who was very close to her face.

She trembled with fear and couldn't say a word.

The waterfall erupted again, and the picture changed again.

"Hui Qianlan, you will be responsible for collecting homework in the future. Remember to come early, preferably before the other teachers come, do you hear? ”

"Listen...... I heard ......"

A waterfall of blood gushed out, and then turned into a snowflake spot.

After reading this, Shi Yuan and the others all looked at Teacher Yan, and the eyes of the two girls erupted with anger.

"It's not serious! What a bastard! ”

"That's it! Forget it when you're dead! ”

Wan Yizhu and Lu Tingting shouted angrily.

"Nope! No! ”

Looking at the picture on the wall, Mr. Yan's face was like earth, and he kept sifting the chaff.
