I didn't move, letting the big pale hand write and draw in my notebook.

Soon he wrote the answer to the question, not only did he write it out, but he explained it in great detail.

I looked at the answer and smiled, "Thank you, teacher, I still have a question that you need to help me answer." ”

The other party was obviously excited: "Oh? Questions? That's the best, ask. ”

I hesitated for a moment and said, "What happens when you die?" ”

The other party obviously didn't expect me to ask this kind of question, and he hesitated for a long time before he spoke: "After people die, maybe they will become ghosts, right?" ”

I slowly turned around, and in front of me stood an old man in a tunic suit, his image was very decent, except for his pale face and fluttering soul, I could hardly find the slightest connection with ghosts.

His eyes were not empty, as deep as an endless starry sky.

His mind seemed to be constantly thinking about all kinds of geometry problems and how to teach his students.

It can be seen that he must have been a very rigid person before his death, with meticulous hair, a neatly repaired chin, and a tunic-free tunic without wrinkles and a very 'dialectical' countenance, all of which show his strictness and harshness in teaching.

"But what the teacher taught us was materialism, saying that there are no ghosts in this world."

I stared at the old man with hope in my eyes.

It seems that this has been a problem for me for a long time, I have seen many ghosts, but I am still not sure if they exist or not.

Because the ghosts I met before had a hard time facing the fact that they were dead, and they still fantasized that they were still alive, so every time there were ghosts that disturbed people, the reason was that their obsession did not dissipate with death.

The old man was reluctant to answer my question, but I waited patiently for a long time.

At the moment, I am no longer like a student asking the teacher questions, but like a teacher who waits patiently for the students to give answers.

Finally, the old man seemed to ponder for a long time before he replied to me: "People have a trace of obsession in their bodies, and they are transformed into ghosts. That's how I saved zài. ”

I sighed, "Then what is your obsession?" ”

There was uncontrollable sadness in the old man's eyes: "My obsession is that I failed to teach a disciple with a perfect score in mathematics in the college entrance examination, I hate myself, obviously I have the most qualifications, obviously my teaching level is the highest, but why, I didn't educate a disciple with a perfect score in mathematics?" ”

I couldn't help but smile bitterly, this lovely and respectable teacher was too sharp.

It seems that I can only try to explain him: "Perhaps, your teaching method is not suitable for today's students, although you have worked hard to educate every student, although you have done your best and died, although you are selfless and have dedicated your life to the cause of education, but these are all your past things, you have gone, then go, why bother to have this obsession and wander between this world and the world?"

You know, you've broken the rules, and that's a stain on your life's work. ”

The old man was silent for a long time before sighing: "Maybe what you said is right! However, I am really unwilling! ”

Ghosts are like that, once they get into the horns, it's hard to turn back.

I changed my words: "You know what I do, right?" ”

The old man's pale face did not make the slightest wave; "You know, I knew from the time you came last night that I couldn't stay here for long. It's just that I don't know why you ran away all of a sudden. ”

Why did I run away? I'm a little annoyed for no reason, I feel aggrieved when I think about it, I was put two tubes of blood, and I don't know who I saved!

I didn't explain too much to the old man on this issue, and what I have to deal with now is his problem, not mine.

I slowly took out a mineral water bottle, and slowly pasted the Genshan charm on it: "Since you know, why did you appear tonight?" ”

The old man said seriously: "Because I want to do my best to give one more student to solve doubts, to let one more student learn a little more, to help one more student solve mathematical problems, so that it is enough." ”

I stopped there, and I couldn't calm down for a long time.

Indeed, as Nobita said, for such a teacher who takes the cause of education so seriously, I can't mention the slightest expulsion mentality, and his meticulous temperament is enough to make me awe-inspired.

Only such a teacher can dare to admit that he is a ghost, can dare to admit his mistakes, and can make our education flourish, but unfortunately, he is dead.

Since he has violated the rule that ghosts should not disturb people, then I must send him away.

I bowed to his soul: "Teacher, you have already gone, shall I send you to reincarnation?" ”

The old man glanced at Nobita, who was sleeping there, and smiled with satisfaction: "Okay." ”

With that, he turned into a wisp of black smoke and burrowed into the mineral water bottle.

I said to the water bottle, "Why don't you resist?" Perhaps, I'll just let you go. ”

Unnaturally, I've used honorifics.

The old man's voice came from inside the bottle: "You have done well enough, although I am stupid, I still know the concept of right and wrong, as a ghost who should not be stored here, I should have gone to reincarnation a long time ago, but, alas! It's all that obsession!

At this moment, I realized that human destiny is predestined, and destiny should be like this, so why should I force it?

I instilled all my life's learning into this child's mind last night, and it can be regarded as a wish, as for whether he can fulfill my wish, let it be! Thank you for giving me the extra night, you're a good boy. ”

What an open-mindedness!

The moment the cap was closed, the last candle was extinguished, and the torch turned to ashes and tears began to dry. I actually burst into tears.

I looked at Nobita in his sleep and found that two lines of tears also flowed from his eyes.

The old man was sealed in a mineral water bottle by me, and he was going to take it back to the village tomorrow so that my grandfather could send him to reincarnation.

With the old man's departure, Nobita also slowly opened his eyes, and shouted with tears in his eyes: "Teacher, I will definitely fulfill your wish." ”

My face turned embarrassed, why did I promise to help the ghost?

Well, I really doubt at this time whether fate is really playing tricks on people, and the old man's wish is nothing more than to teach a student with a perfect score in mathematics in the college entrance examination.

Before his death, he didn't fulfill his wish, and after his death, he actually pressed the treasure on the head of a high-priced student who was proud of being naughty and mischievous, lazy and cunning, could his wish come true?

If he can't fulfill his wish, won't Nobita be unlucky?
