The autumn wind is getting colder, and the winter is becoming more and more obvious.

Another week passed, and October entered the second half of the year.

Monday morning.

Because there is a routine *** in the gymnasium, the morning shift of class C of the year will end in a hurry.

The front door of the classroom opened, and a cold wind suddenly poured in, and Nakahara Xue shrank her neck and raised her voice: "If you feel cold, you can wear a coat, but you can't wear a scarf and gloves."

When Naruse heard this, he could only take off the scarf around his neck.

"Is it cold?" Naoko looked at him.

"It's fine." Naruse shrunk his neck and let out a white breath, "Let's go to the gym."

Assemble in a queue and go downstairs to the gymnasium, where the sun does not shine here, and the non-stop cold wind blowing in the passage makes people shiver.

Naruse's teeth chattered from the cold, and he wanted to hide all the skin in his uniform until he walked into the gymnasium.

"It's finally windless......

When passing by the third-grade array, he glanced at it more, and the seniors who had gathered here first exchanged their heads and ears, faintly excited.

He quickly guessed the possible cause.

"It's been two weeks, so I guess it's about the same."

"What?" Naoko doesn't know why.

"School trip...... There's probably some gossip coming out."

Sure enough, after the assembly, the first thing Kobayakawa announced at the routine *** was the resumption of the third-year school trip.

And the time of departure is tomorrow.

「YES！ YES！ YES！」

"Finally ......!"

"Kyoto, school trip, I'm here—"

The irrepressible excitement of the third-year students was clearly transmitted even through the middle second-year.

The students of the two grades looked at the seniors over there.

Rather than envy, Naruse saw more confusion on the faces of his peers - when it was their turn to go on a school trip, there would be two more years.

There are exceptions.

Hikaru Takikawa, for example, frowned.

"I'll leave tomorrow......

"It's going to snow if it drags on any longer."

"Just cancel it."

"That's too cruel for a third-grader." Naruse understands that she is still not too worried about her delicate sister going far away.

"Tsuki should be happy by now......" she stood on tiptoe and looked over to the third grade.

At the end, Hikaru Takikawa did not return to the class with the team and left halfway.

Naruse estimated that she was going to find Takikawa Tsuki, and he didn't care about her.

When the first class in the morning was over, Hikaru Takikawa took the initiative to find him and Shangzi.

"Let's go."

"Hmm."

The second lesson is biology, and today's lesson is about dissecting squid, and I am going to go to the biology classroom. The three of them are in the same group.

The biology classroom is on the ground floor of the annex building, which used to pass through the connecting corridor between the main and auxiliary buildings.

The cold wind was blowing, and Naruse tightened the scarf around his neck, and his face was also lowered.

The scarf was newly woven by Naoko. Because she felt that the scarf she had sent him before was a bit shabby, she spent two nights re-knitting it after she wanted to go back, and it was warmer and more beautiful than the original.

The cold froze the faint smell of hand cream on the scarf, and Naruse wrapped it tighter.

Hikaru Takikawa looked back, "Harumi is really afraid of the cold."

"Because it's not supposed to be so cold......

She laughed, "This is Tohoku, not Tokyo."

Naruse didn't speak, and a cloud of white gas came out of the scarf.

As he approached the entrance on the other side of the connecting corridor, Hikaru Takikawa suddenly said, "Then let's go to some places that aren't so cold."

Naruse raised his eyes to look at the annex building in front of him, "Hmm."

She turned her head to look at him and smiled again, unbelievably meaningful.

When they came to the biology classroom, the three of them found a place in the front, and the squid specimens to be used for dissection were already placed on the experimental table.

Hikaru Takikawa reached out and touched it, the slippery and cold feel made her reluctant to touch it again, "Dead."

"Of course the specimen is dead."

"Looks pretty fresh."

"If it's rotten, there's no point in dissecting it."

Naoko looked down and sniffed, "There's a strange smell."

"I guess I soaked it in formalin solution before." Naruse pulled her back a little, "Don't sniff."

She smiled, "Okay."

Before class, biology teacher Reiko Kuroda was busy writing the experiment process and requirements on the blackboard, and she didn't have time to take care of the following, and a few boys suddenly made a noise.

"Teacher, Tokawa ate the squid!"

Kuroda was startled and walked down quickly, and the squid specimen on the table was indeed gone, "Are you stupid! Spit it out!"

And before she could get to the bulging mouth of Tokawa, the squid slipped out of his sleeve.

「……」

The result, of course, was a reprimand.

The farce ended in a hurry, but it also delayed some time, the class bell rang, and Reiko Kuroda's board book was not finished yet, so she had to speed up and write hard.

After a minute or two, she put down the chalk and started the lesson.

"We're going to dissect the squid in this lesson, but before we get started—put the squid down!"

Following her line of sight, Naruse turned around, and the boys at the back of the classroom began to play with the squid specimen again.

"Boys are stupid...... "Girls are stupid" In the noisy classroom, the girls huddled together and exchanged ears, "except for Naruse-san."

Naruse, who was unexpectedly complimented, could only laugh dryly.

「…… The purpose of the squid dissection experiment is to understand the characteristics of cephalopods that adapt to a lively and athletic lifestyle, and to understand the internal organ structure of mollusks."

Reiko Kuroda pointed to the words written on the blackboard, "Before starting the experiment, I need to explain the experimental equipment."

After introducing the tools such as dissecting scissors, tweezers, and dissecting wax plates, she asked her students to formally observe today's test subjects.

Seeing that Naoko and Hikaru Takikawa were both looking at him, Naruse had to take matters into his own hands and take the squid into the dissecting wax tray, the darker one facing up.

"Now look at the external form of the squid, distinguish the head and feet, neck, and torso, as well as the main features of each part."

Naoko handed the magnifying glass to Naruse.

"The neck is so short." He bent down to observe for a moment, then gave her the magnifying glass, followed by Hikaru Takikawa.

"Is this the squid caught in Mutsu Bay?"

"I don't know."

"I'm craving seafood."

"You can't eat this."

Before this class, homework was assigned, and I was asked to draw a diagram of the squid's outline, as well as a sketch of the internal structure.

Takikawa Hikaru painted it several times, but it still didn't look like it, so he simply depicted it according to his paintings.

"Hmm...... At least it doesn't seem so weird."

Naoko draws very well, and some parts are more detailed than Naruse.

After a while, the external observation part is finally over, and the internal dissection begins.

Reiko Kuroda pointed to the picture on the projection screen and raised her voice:

"The dissecting scissors enter from here, first cutting the sides of the mantle, and then removing the ventral mantle to expose the visceral mass inside...... Look, I'll show you first."

She manipulated it a few times, and the projected content became her real-time operation on the lab table above.

"Enter from here, be careful when cutting......

After watching her operate it completely, Naruse looked at the two people beside him again, "Or am I coming?"

"I'll try

Try it." Naoko said.

So he gave up his position and stood next to Hikaru Takikawa left and right, watching her operate.

Picking up the scissors, Naoko didn't even look up at the projection screen again, and the knife was accurately and neatly removed, and the mantle of the squid's torso was removed in three or two clicks, and the incision was still very smooth.

"Naoko may be able to become a surgeon in the future, and this hand must be very stable with a scalpel." Hikaru Takikawa exclaimed.

Naoko smiled and looked at Naruse.

"It's a nice cut."

"Uh-huh."

The students at the bottom operated, and Reiko Kuroda went down and took a turn, and also gave Naoko a very high evaluation.

The squid used for the experiment were all females, so when the mantle was removed, the exposed visceral mass revealed a bulging white ovoid gland, as well as a larger number of accessory egg glands;

Due to the limited time available for the lesson, the last step in today's dissection is to remove these glands and observe them again.

Hikaru Takikawa still has no interest in getting his hands dirty, so Naruse picks up the tweezers.

"Be careful when removing ......"

The biology teacher reminded him on stage, and Naruse lowered his head, holding down the squid with one hand, and carefully separating the internal organs from the body with tweezers with the other.

"-By the way, Harumi will come with me to Kyoto tomorrow."

Poof!

The sudden tear caused the gland to detach directly, and the cold liquid also splashed on his face in the shake, Naruse was stunned and turned his head to look at Hikaru Takikawa.

"What?"
