The front row passed the scroll to his hand, and Huang Ping looked at it with disgust, it turned out to be mathematics.

For some reason, he is not interested in science, especially mathematics, at all, and he has a feeling of constipation every time he does calculations. And his tablemate Izumi Na is an all-round honor student, even in a subject like mathematics that requires strong logical thinking, she can be fearless and can be at the top every time.

After a while, the classroom sounded the sound of rustling brushstrokes, and everyone was immersed in calculations, except for Huang Ping, who was alone with his right hand on his cheek, staring out the window boredly.

Speaking of which, the environment in this cave is not much different from the ground, artificial sunlight provides photosynthesis for trees, and there are no cloudy days throughout the year, and there are plenty of sunshine hours, so the trees grow quickly, the branches and leaves are luxuriant, and the dense dark green leaves make a rustling sound under the blowing of the artificial breeze.

The head teacher glanced at Huang Ping from a distance, but didn't pay attention to him.

It is a recognized fact that Huang Ping's math scores are a mess, and she has also talked to Huang Ping, but unfortunately the effect is not great. Over time, she also lost faith in the child.

I don't know how long it took, but Kohei's right arm was poked by something hard.

Huang Ping raised his eyes to see that he had a nervous and red face, holding a pen in his hand, and he looked like he wanted to speak and stopped.

"Throw it at your feet." Izuna said softly.

Huang Ping looked at her paper, it was still blank, this girl actually answered the cheat sheet for herself first, and completely ignored whether her test paper was finished in time.

Hey, why did I turn a blind eye to this true feeling at that time?

He couldn't help but think of Meijia's mature and moving figure again, and when he thought of the affection that he couldn't pay off in his life, the whole person froze there.

Seeing that he didn't move, Izumi thought that his stubbornness had come up again, and couldn't help frowning, and tears were about to fall, but she didn't dare to move in the examination room, until Huang Ping pretended to pick up stationery and picked up the paper ball, she breathed a sigh of relief, wiped the tears that were about to roll down, and focused on her test paper.

Huangping unfolded the paper ball, and Izumi Na Juanxiu's font wrote the answers very neatly, and even the big questions were not left word for word.

Huang Ping smiled bitterly, just filled in the score of about 60 points, and then began to be stunned again. Everyone knows his math scores, so why should he copy so much, but he can't find it at ease.

The bell rang for the end of the second period, and the students stood up in droves and handed over their papers to the front of the stage. After the head teacher collected the papers, he commanded, "In the next two classes of self-study, the students will finish the papers I sent out yesterday." ”

In the midst of the noise, Kohei suddenly whispered to Izumi, "We'll meet in the corridor of the small garden in the next class." ”

After saying that, he first put his pockets in his pockets and walked out, leaving Izuna with a blushing face lying on the table, his heart pounding, and his whole body was as sweet and crispy as eating honey.

Although Izumi has never skipped a self-study class, she can't care so much about it under the inspiration of love, and there is no teacher to watch the self-study class anyway.

Kohei sat on a wooden bench deep in the small garden, and when the class bell rang, a sparrow was startled around him.

After staying in this underground city for a long time, sometimes he really felt very comfortable here, how could he have thought that this place would be destroyed one day.

After waiting for a while, Kohei saw Izuna coming from a distance in a bit of a panic, his cheeks were red, like ripe peaches.

"Kohei-san, that ...... Wouldn't it be nice for us to come out during the self-study class? Izumi pinched the corners of her skirt with both hands, and she dared to look at Huang Ping.

Kohei looked around, because of the class, the small garden was quiet, and there were occasional birds and insects, but it seemed more quiet.

"Izuna, can you sit next to me? There's one thing I have to tell you. ”

Izuna's heart is about to jump out of his throat, his palms are full of sweat, and he has been suffering from unrequited love for a year, has this guy who has always been so cold on the outside finally enlightened?

She lowered her head and looked at her toes, "That...... Kohei-san......", she said as she sat down next to Kohei, her big watery eyes full of joy, "Say it, I'll listen." ”

Kohei's expression became grim, "Izuna, you must not think I'm being alarmist when I say it later. ”

Izuna let out a "huh", and her expression became confused.

"In two days, the day after tomorrow, this underground city will be destroyed. All of us will die. There are no exceptions. ”

Izumi didn't expect her to be excited for a long time, but she heard such a strange talk like a dream from Kohei's mouth. She was disappointed, her head hung down, her long thick hair obscuring her face, and her voice became sluggish.

"Hmm...... It sounds scary. ”

Izuna is very disappointed, and her emotional setback today is more sad and disappointed than tomorrow's extinction of all mankind.

Kohei noticed Izuna's emotional reaction, but time did not allow him to fall in love with Izumi, and at this moment he could only take advantage of Izuna's persistent love for him.

"Listen to me, Izuna, we still have a chance to save all this, you just need to help me steal the key to get in and out of the research institute."

Izuna's father is the head of security at the institute, who is responsible for the security of the institute, and his office has a huge screen with small squares on it, and all the surveillance footage is played in real time.

Kohei had gone in with his father to visit, so he was very impressed.

Izuna lowered her head and did not speak.

Kohei grabbed Izumi's arm, and his fingers couldn't help but increase the force.

"You're hurting me." Izuna frowned.

"I'm sorry, I'm really just too anxious, I don't want my parents and your parents, everyone in this city to disappear in an instant."

Izumi's eyes were still full of suspicion, "Is it really that serious?" ”

"Trust me."

After thinking about it for a long time, Izuna said, "Okay, after school in the afternoon, I'll go to my dad's to try it." But whatever you want to do at the institute, you'll have to take me with you. Otherwise, I don't feel at ease. ”

In order to enter the research institute to find out, he knew that there might be hidden dangers, so he had to agree.

Izumi Nai smiled slyly, his mood seemed to have recovered, he didn't expect that Huang Pingjun was already in his first year of high school, and the second year of secondary school had just begun, maybe he wanted to be a savior, so he would accompany him for a willful time, after all, he could have a chance to get close to him, wouldn't it.

Where did Kohei know about Izumi's careful thoughts, and seeing that things had finally progressed, he couldn't help but breathe a sigh of relief, and said, "Izumi, you go back to the classroom first, and I'll be there later." ”

Izuna hummed obediently and turned away gently, her fluttering white dress like a blooming flower that would never wither.
