"Yo! Good morning Nobita! An Xiong greeted Ning Jiusi warmly: "Have you finished your summer homework?" Do you need me to borrow you? ”

"No need, it's already done...... Ning Jiusi waved his hand with a deep face: "Thank you for your kindness, Anxiong, I'll go to the classroom first...... I'm so tired~~~~"

"Nobita is not in good shape. Pen, Fun, Pavilion www.biquge.info" Anxiong flicked his new hat, turned his head and saw the fat tiger and the little man who came in, and immediately stepped forward: "Yo! Fat Tiger! Husband! Good morning! ー”

"Yasuo...... Hello......" Fat Tiger replied casually: "I'll go to the classroom first, Anxiong...... I'm so tired~~"

"Hello, Anxiong, I'll see you later......" The doctor also responded casually: "I'll go to the classroom to sleep first~~~~"

"Fat Tiger and Xiaofu are also in such a bad state? Did they do something shady last night? Anxiong thought about it, raised his head, saw a beautiful figure past, and immediately beckoned: "Hello!" Belle...... This one...... Uh~~ "Hello President...... I didn't harass anyone just now......"

"I know, little Yasuo's hat is still so funny." Midorikawa Seina said with a smile: "I'll forgive you for being unreasonable when you see me called a beauty, so I'll see you in the classroom later!" ”

"It hurts, ......" covered his head, Yasuo couldn't get up for half a day, Midorikawa Seina used a lot of strength just now, making Anxiong feel like his head was going to fall off, and I don't know how he provoked this violent student president again, forget it, look at the time, it's class time, let's go to class first! The bell of the morning class rang, Ning Jiusi yawned and looked outside, it was really a leisurely start to the day, I didn't expect a school to start is a good thing, I never thought that I could receive a normal education in the classroom when I started school, not Han Lexin's kind of education, it was completely an education that squeezed my potential! Or is it better to go to school......

"Nobita!" The voice appeared next to Ning Jiusi, which scared Ning Jiusi for a while, and instinctively sat down neatly, seeing the teacher holding the list of points and looking at him on the top.

"Here!" After Ning Jiusi recalled for a long time, he finally hurriedly answered, and at the same time, he unconsciously compared the zombie of the teacher he saw in the Resident Evil world before with the current appearance, and compared the zombie teacher who lost weight very successfully.

"Nobita, you didn't be late today, you did a good job." The teacher nodded to Ning Jiusi: "I also heard about your summer vacation, I am very optimistic about you, keep up the good work!" ”

"Oh...... That one...... Thank you, teacher. Ning Jiu thought about it, from the memory of Nobita who was fused, and he was instinctively afraid of the teacher, but was Nobita in the original book really so afraid of the teacher? I don't feel right, and I've been teasing the teacher many times......

"Fat Tiger!" The teacher didn't hear Ning Jiusi's words, but continued to name and set the fat tiger on fire.

"To !!!" The huge roar made the teacher almost fall to the ground, and after wiping the sweat, the teacher said in his heart that it really deserved to be the voice of the fat tiger...... Capable of exterminating rodent-infested vocals......

"Little man!" The teacher continued to roll call, and the names of Ning Jiusi and the three of them didn't know how they got together.

"Here!" Although the husband's state is not good, his voice is still very loud.

One by one, the names continued to be clicked by the teacher, and Ning Jiusi at the bottom began to wander again, and casually took out a book from his schoolbag to concentrate his attention, but when he saw this famous quantum division mathematics thing, he felt uncomfortable in his head again, and he didn't have the help of Han Lexin, who was studying at home, looking at this is simply looking for death!

"Next, let's do a little test." The teacher spoke above, and what he said about Ning Jiusi's instinct was a trembling, from Nobita's memory, a little afraid of the exam or something, although it was just a reaction, in fact, whether it was Ning Jiusi or Nobita, they were both guys who dared to face the bleak life...... Why do you feel a little depressed when you say that?

The exam paper was sent down quickly, Ning Jiusi looked at this super difficult topic and had to bite the pen hard, anyway, most of the questions were recognized by Ning Jiusi, Ning Jiusi did not recognize them, and the few people who knew Ning Jiusi did not dare to guarantee the accuracy rate, and after nearly two months of surprise study, it was almost as if he had not seen any progress...... When I finally handed in the exam papers, I was sure that I would definitely not be able to combine, depressed, depressed!

Ning Jiusi originally had any hope that he would not report for this exam, but when it was time to leave school, the teacher came to hand out the papers, but found Ning Jiusi, Fat Tiger and Xiaofu.

"All three of you have made progress this summer." The teacher's first sentence made the three of them scratch their heads, and when they saw the scroll in their hands, they were ecstatic...... Except for Ning Jiusi, Fat Tiger and Xiaofu were all ecstatic.

"Nobita, I know that you have worked hard, and you have studied secretly for a month more than Fat Tiger and Xiaofu." The teacher patted Ning Jiusi on the shoulder, and said earnestly: "But you must know, now your score is already a great improvement, this test is so difficult, I am still worried that you will get a zero score again, the score of thirty points is already very good, Fat Tiger and Xiaofu are just this score, go back and continue to work hard!" The teacher is confident that you will get a higher score! ”

"Thank you, teacher......" Ning Jiusi sighed and thanked him, but he still couldn't accept this thirty-point score, if he had won this score before, my sister would be sad, right...... alas

With a sigh, Ning Jiusi left the teacher's office, making the teacher a little worried about this: "Nobita is a little too ambitious, this is not good, you should talk to Nobita's mother about it, don't put too much pressure on the child." ”

This summer vacation, the naughty Nobita began to study hard and exercise hard has spread in this neighborhood, as a teacher who pays attention to his students from time to time, he naturally knows about it, and he also went to Nobita's house once to see Ning Jiusi, and saw a group of people being forced to learn the knowledge of his brother's subjects from scratch, he was very pleased, but he didn't want to let his students become nerds because of this, it is enough for nerds to have that one out of the wooden shirt, relative to the future, He is actually more optimistic about a child like Nobita, he can maintain an optimistic attitude at any time, and he will not despair when he is hit to that extent, which is really a rare quality, if he can be lucky......

"Ahh Ning Jiusi sneezed firmly in the corridor, turned his head to look around, and didn't understand how he was cursed inexplicably, and then spread his hands after looking left and right: "Forget it, let's go home first!" It's rare to have a break today, go home and see what Xiao Xin has come up with today. ”

"Nobita, I'm back!" Nobi Yuzi greeted Ning Jiusi, who was changing shoes at the door of the house, and was stunned after seeing what Ning Jiusi was trying to hide: "Test paper?" Come and show my mother, I won't say anything about you today, after all, we have seen your efforts these days, come ......"

"That...... Mother, I'll go back first. Ning Jiusi saw the stunned Yebi Yuzi, and hurriedly said, turned his head and walked into the room, he only scored thirty points in the exam, and he really didn't have a face to see people! I don't want to be scolded anymore.

"Oh my God, I was able to score 30 points at the beginning of the exam." Nobi Tamako sighed: "Nobita, you have made great progress!" What about Nobita? Did you go back...... Forget it, let's make them something nice for dinner! ”

Just after the decision was made, a terrifying roar came "What?!?! The sudden voice almost scared Nobi Tamako, was it Doraemon's angry voice? Nobi Tamako was very curious and continued to listen to the other side: "Only thirty points? What do you eat? It's so low!!! Didn't even pass...... Me, forget it! Give me half the break tomorrow!!! ”

"Okay......" Ning Jiusi's voice made Yebi Yuzi feel a little heartbroken, after thinking about it, it was better to talk to Doraemon at night, and now Doraemon who is angry doesn't want to mess with her.

At this time, here on the second floor, Ning Jiusi was very depressed and watched Han Lexin take out something after being yelled at, and was very puzzled: "Xiaoxin, what are you?" Why does it make me feel a little weird? ”

"It's something that changes time and regularity within a certain range." Han Lexin put the wine bottle aside and said, "What I took out in the morning seems to be something that Doraemon often uses, and it seems to be suitable to put it here now." ”

"What's the function?" Ning Jiusi was puzzled, looking at this one, it seemed that Nobita's memory was also very familiar, but there were not many specific memories, and bad memories were also Nobita's fault...... Same problem as myself.

"There are a lot of features, and the most critical one is very useful to me." Han Lexin fluctuated the machine that he couldn't understand, and only nodded after a while: "Okay!" Ning Jiusi, from now on, you are a fourth-grade student again, but the textbook you have to study will be a fifth-grade one. ”

"What do you mean?" Ning Jiusi was shocked, the teacher had just said that he was already a fifth-grade student in the morning...... How so?

"I guess that's why Doraemon World has always been in the fourth grade of elementary school." Han Lexin nodded and smiled: "It's quite interesting, let's start learning!" ”

"Didn't you say you could rest today?" Ning Jiusi was depressed: "I talked to Fat Tiger and them about going to the back mountain to play." ”

"Embarrassed by your grades?" Han Lexin was angry: "You want to play when you only have thirty points? You are not allowed to go out until 90 points! Do you know?! (To be continued.) )
