At dusk, Huiyuan Ai returned to the gate of Didan Primary School.

The retractable door that is half a meter open indicates that the people inside have not yet left.

Haihara Ai came to the guard room at the end of the retractable door, stood on tiptoes and knocked on the glass.

Benefit, Benefit...

After a while, a security guard with peach-shaped hair and thick eyebrows opened the glass window and looked around.

"Who?"

"I'm here."

Haiyuan Ai squeaked, and the pink-cheeked security guard noticed the short primary school student.

This security guard had worked at Didan Primary School for more than ten years and had the habit of drinking during the night shift. Now that it was close to night, he became tipsy first.

"It's you...what? Did you leave your homework at school?"

The security guard didn't actually know Haibara Ai, but it was just the reason why primary school students came to school on holidays.

"no."

Haiyuan Ai shook his head and asked calmly: "I want to ask if you know a former student of this school named Miyano Akemi?"

"Miyano Akemi?"

The security guard turned his eyes in other directions and thought for a moment, then shook his head.

"I don't know."

Hearing this answer, Haiyuan Ai's heart suddenly became cold.

Because if you don’t know Miyano Akemi, it’s naturally impossible to know when Miyano Akemi went back to school when she grew up.

This also cannot prove that Miyano Akemi ever returned to school and took away her own envelope in the time capsule.

At this moment, the security guard's pupils were suddenly startled, he stared at Haiyuan Ai's face and said in surprise: "I remembered!"

Hui Yuan Ai suddenly raised his head, his eyes shining.

"You are the student who came over to clean the breeding hut this afternoon, right?"

Hui Yuan Ai: "..."

Hui Yuan Ai grinned, a little helpless, feeling that this old man had just recognized him.

The security guard held his chin up and continued, "You guys took the initiative to clean up the breeding hut, right?"

"Yeah." Haiyuan Ai nodded lightly.

The security guard raised his chin and rubbed his chin in understanding, "I thought it was the new teacher Wakasa who called you to help with cleaning. She even took the initiative to help clean the roof of the breeding hut in the afternoon..."

"Well, if she likes to clean up there, my work will be lighter in the future."

The security guard is settling his own little account, because cleaning the breeding hut is also part of his job.

If only students and teachers had taken the initiative to clean up, he would have been saved from trouble.

But when Hui Yuan Ai heard the security guard's words, the expression on his face suddenly froze.

What does it mean for Rumi Wakasa to help clean the roof?

It was obvious that he and the Young Detective Team were responsible for cleaning the place today...

"Uncle! When did you see Mr. Wakasa cleaning the roof of the breeding shed?"

"It was in the afternoon. I saw her cleaning there alone..."

The security guard was a little stunned by Haihara Ai's sudden serious attitude, but he still looked in the direction of the breeding hut.

From the inner window of the security room at the school gate, you can see the conditions of the breeding huts on campus.

And Haiyuan Ai's pupils suddenly dilated, and he suddenly realized something in his mind.

If Rumi Wakasa had gone to the breeding shed alone to "clean the roof" in the afternoon, and the security guard happened to see her...

Then she should not be cleaning there, but looking for the time capsule!

The letter left by Miyano Akemi that is missing from the time capsule was probably taken away by her!

Thinking of this, Hui Yuan Ai couldn't help but froze on the spot.

After a while, she slowly turned around amid the security guard's concerned questions and walked back home.

But her steps were like a walking zombie that had lost its soul.

Why?

Why did that woman take the letter left by her sister?

Did she ever know her sister?

Or did she see the intentions of those graduates?

Haibara Ai's mind seemed to be trapped in some kind of thinking spiral, and the same questions kept repeating in her mind.

Unknowingly, she walked into the alley next to the school.

The setting sun shone in the alley, and a long and narrow figure looked particularly dark, like a twisted tentacle, reaching out to Hui Yuan Ai's feet.

Hui Yuan Ai, who was walking quietly with his head lowered, saw the shadow in front of his feet and subconsciously stopped.

She was stunned for a moment, then slowly raised her head to look.

I saw the owner of this shadow standing in the middle of the alley.

The backlight of the setting sun made Haiyuan Ai unable to see the man's face clearly for a moment.

But as her eyes adapted to the light, as well as the outline of her long shawl hair and the reflective lenses on her eyes, Haihara Ai's pupils suddenly tightened as she realized something.

It’s Rumi Wakasa!

Rumi Wakasa stood in the middle of the alley, her hands hanging naturally on both sides of her body, looking here expressionlessly.

Although from an ordinary person's perspective, Wakasa Rumi just stood there motionless, in Haibara Ai's eyes, she had a sinister aura about her.

It's as if the god of death is coming, with a chilling aura...

The thoughts in Hui Yuan Ai's brain paused for a moment, and then his body subconsciously turned around and ran away.

But when she just turned around, she saw a man blocking the exit on this side of the alley.

Under the illumination of the setting sun, Haihara Ai clearly saw the man's appearance.

This is a man in a black trench coat with a somewhat delicate face but a shaggy beard.

The next moment, Hui Yuan Ai's heart was throbbing, as if it was about to jump out of his chest uncontrollably.

Boom!

Boom!

Be a member of the organization!

Haihara Ai's radar reaction was triggered, and the dark silhouette of a huge organization immediately appeared in his mind.

what to do?

Caught!

Hui Yuan Ai's body was leaning stiffly, and the survival instinct in her mind was to escape.

But in this desperate situation of being attacked from both sides, and unable to adapt to the throbbing caused by the organization in a short time, she could only keep looking in two directions.

The look conveyed in the poignant eyes is a kind of helpless despair.

elder sister……

At this moment, Rumi Wakasa's figure moved first.

She raised her arms, kicked off her left foot suddenly, and rushed towards the middle of the alley in the most standard athlete sprinting posture.

Her whole person exuded a cold and powerful aura.

Hui Yuan Ai subconsciously wanted to hide, but under the control of fear, her body could not move at all.

The man on the other side took out a silenced pistol from his arms.

Piu——

Piu——

The bullet traced a spiral trajectory in the air and shot straight towards Haihara Ai's head.

But at the critical moment, Wakasa Rumei rushed forward with all her strength and hugged Haibara Ai in her arms.

The bullet grazed the tip of the brown hair, and then shot through the thick black hair.

Wakasa Rumi threw Haibara Ai to the ground, but caught the back of her head with her hand and did not cause any harm to her.

Haiyuan Ai stared blankly at the cold face less than 20cm away from him, his brain completely shut down.

The moment Rumi Wakasa landed, she had already raised her hand to pick up the garbage cover on the ground next to her and threw it towards the killer like a flying saucer.

Piu——
