Cherry blossoms flutter in the wind, announcing the arrival of spring. Today's Youyin High School, the fourth class of the second year of high school also happened strange things.

"Thus under this condition, this system of quadratic equations represented by the extension line Y of the fixed point A............ Hatch! "In the classroom, the teacher on the podium shook his body and trembled to talk about the topics in the book.

However, all the students under the podium fell asleep.

"In other words, substituting XY....""Smack!" The teacher's face fell on the podium as he spoke, barely supporting his sleepy body.

"Why, how can you admit defeat! I can't fall asleep, how can a teacher fall asleep during class! The teacher lifted his bloodshot eyes, his eyelids were still supported by matches, but there was no use for birds, and the strong sleepiness overwhelmed the matches that supported his eyelids, and the matches flew out, and the teacher struggled to turn around, lying on the blackboard, scratching the blackboard with his fingernails, trying to sober himself up.

"Bastards, you, are you still awake? Cheer up! Perk! Calculate from this system of equations....... Such..... Purr! "I tried to draw an arc, and finally the teacher also fell.

"That's not true! If this continues, won't our country's education fall to the bottom of decadence? But it's so sleepy! The only two students left in the class, Jotaro Mido looked at the fallen teacher and sighed angrily.

Suddenly, a powerful drowsiness rushed to the brain, and the eyelids began to fight, "No, no!" If even I can't be rational! Well!!!! Jotaro Mido rubbed his eyes to prevent himself from falling asleep, and when he looked to the side with his spare eyes, he was surprised to find that Zhu Xingchen was actually sitting in his place and looking intently at the textbook.

"Even that bastard Zhuxing can burn his eyeballs and take class seriously! How could I lose to that guy! I definitely can't fall asleep and bet on the self-esteem of an excellent student! After speaking, Miantang took out a bunch of oral liquid from his bag and sucked it vigorously.

What the hell are the stars doing at this time, "This, this is amazing! Zhu Xingchen looked intently at the little yellow book covered in the textbook cover, and was reluctant to blink at all.

Outside the window, an extremely small voice came from a cherry blossom tree.

"Sleep~ Sleep! There are two people left! Ah Qiu, Ah Qiu! Let's sleep~ Let's sleep! Aqiu, Aqiu, Aqiu! Oops, I'm exhausted! A little man in a red cheongsam with pink hair shouted a spell at the classroom of the stars, shouted for a while, and then lay down and lazy.

"Spring Sleep!" An old man suddenly burst out and shouted at the girl.

"Ahh Chunmian hurriedly stood up.

"Such a simple spell, you just give up! What are you doing? The old man said.

"Ahh Chunmian said.

"Listen, you won't be able to rise to the rank of a second-level elf unless you let everyone in that classroom fall asleep! Don't you see that there are still two people who are not asleep? Hey, are you listening? The old man said as he tapped Chunmian's head with a wooden stick.

"Sleep~Sleep~Sleep~Sleep!" Chunmian shouted a spell helplessly.

"Fifteen minutes left until the time limit, got it?" After the old man finished speaking, he walked to the side and sat down and muttered: "Really, although there is always a crane tail every year, this is the first time I have seen this kind of inferior student!" ”

"That's because the teacher is incompetent! Let's sleep~ Let's sleep! Chunmian said quietly.

"Hmmm! What did you just say, what did you just whisper! The old man shouted in front of Chunmian.

Back in the classroom, "That's really, quite!" Zhu Xingchen glanced at the little yellow book and sighed.

"Hey! You guy, stars! Suddenly, Zhu Xingchen felt that his head was hit, and then reprimanded, the frightened Zhu Xingchen said nervously: "Old, teacher! There are many complicated reasons for this! It's best to suppress sleep or something, or use this! Well???? When Zhu Xingchen finished speaking, he found that there was no teacher, and then he looked up and saw Ram greeting: "Hi! Darling! ”

Zhu Xingchen reluctantly put away the book, Ram flew over and grabbed Zhu Xingchen's hand and said, "Now, let's go enjoy the flowers!" The weather is so good, let's go and enjoy the flowers! Darling! ”

"Don't talk stupid. It's class right now! Zhu Xingchen said.

"But everybody's asleep!" Ram said.

"Nani!" Zhu Xingchen looked around, and sure enough, the students around him all lay down and went to sleep.

I only met the hall and walked up to Zhu Xingchen, picked up his book, and looked at it, "I thought you were concentrating on reading the textbook, but it turned out that you were reading this kind of thing!" Mian Tang threw the book aside and said disdainfully to the stars.

"Can't you! You may not know that every year when the cherry blossoms are in full bloom, there will be a group sleep event in this classroom! It is said that the students ...... in the spring This figure ...... Will sleep in class all the time, and finally ...... The curve of this buttocks is really unbearable...... will lead to repetition! Zhu Xingchen picked up the little yellow book that was thrown away by the noodle hall and said while reading it.

"Stars! What the hell are you talking about! Miantang shouted to the stars.
