My Partner is Shiina Mashiro

"Combining the time difference within the school, the time on the monitor is 22:25, but the actual time should be 22:35..."

It doesn't seem right, Zhenbai seems to remember that the time difference between the school and the school should be adjusted back by the school.

"No, the actual time is also 22:25."

The director of the security department answered Zhenbai's doubts in a timely manner.

"It seems to be because of feng shui? After Ebina Jicai fell from the building, the school board asked someone to adjust the time difference in the school."

In the end, it was just to cover up the evidence and comfort myself, but fortunately, Mashiro's memory was not wrong. Since the school time does not need to be considered, the time when Yuigahama Yui appeared in the basement was 22:25.

I just found out from Hihama Yui's whereabouts... Then when did Hikigu Hachiman, another victim of this case, enter the basement?

Did he discuss with Yuihama Yui in advance to meet up, or did he break in by accident? Even the surveillance video didn't record it. It can't be said that Hikigaya Hachiman dug a hole into the basement, right?

Zhenbai asked the director of the security department about his doubts, but he got an unknowing answer.

That basement has always been a secret place of Zongwu High School, not to mention the students, even the director of the security department only knows that such a place exists.In addition, the key to the basement has always been stored in the hands of the newly dismissed director of the Academic Affairs Office, Haruichiro Kogu, and the director of the Security Office wondered how Yuihama Yui got the key.

......

After leaving Sobugao's security room, Mashiro did not choose to act with the police. More precisely, Megushisan did not allow her to act with the police.

It is okay to tell Zhenbai the information, and it is also okay to let Zhenbai walk around the campus, but it is absolutely impossible for Mu Mushisan to agree to act together.

Zhenbai was wandering aimlessly, she didn't have a clue and didn't know where she could go next.

I'm used to working with Gilgamesh. Gilgamesh, who is super active, will always solve problems in the most direct and effective way... But now, Gilgamesh must hate herself.

Just walking like this, even Mashiro didn't know why he walked into the small garden of Sobu High Court.In this place she saw Yukinoshita Yukino, the iceberg girl curled up on the ground without saying a word.

"Student Yukinoshita?" Mashiro asked tentatively, "What are you doing here?"

"Nothing..." Yukinoshita Yukino shook her head, "I'm going home too."

"...Could you please help me?"

Mashiro anxiously grabbed Yukinoshita Yukino's arm.

"Before, Sen also relied on your strength to solve the case. This time it's the same. Can you get rid of your assistance in the investigation?"

"Although I still owe Police Officer Liu a huge favor..." Yukinoshita Yukino shook her head with a look of fear, "but now I can't do it at all."

"...Why is this?"

"Because I have a feeling that this kind of thing won't end here..." Yukinoshita Yukino replied, "Ebina Himina and Hayama Hayato are now my members again...Obviously they are my members Party member, I must seek justice for him."

"But I can't do it... I can't do it at all..."

Yukinoshita Yukino looked blankly at the azure blue sky, and now thinking of the days she stayed in the detention center, she was still terrified for a while.

"Although I know that assisting your investigation is the correct behavior, I should do so in public and private..."

"But now I have such a feeling... I always feel that I will be the next to die."

Yukinoshita Yukino's words were full of apology, but she didn't stop her leaving.

"The current Zongwu High School doesn't look like the place I know, it's better to say—"

"It's not an exaggeration to say that this place is a hell... I don't want to stay here anymore."

Yukinoshita Yukino has left, and even the black-haired girl who did not hesitate to take the blame for her classmates has become like this. Once the incident spreads, what kind of consequences the panic will cause to other students, in fact, there is no need to think about it of.

Yukinoshita Yukino left the small garden of the high school courtyard at noon, leaving Mashiro curled up on a bench, feeling sad alone.

"As expected...Leaving Sen and Jill, I became a useless person again."

As soon as the investigation of the case started, Zhenbai encountered difficulties that could not be solved at all. He could not enter the scene and did not know where to start the investigation.

Recalling the days of adventures in the past, it seems that Liu Sen and Gilgamesh solved all the troubles every time.Zhenbai does not have Liu Sen's rich experience in survival games, nor does he have Gilgamesh's extraordinary force, and his only clever little head can't help her at this moment.

A futile sense of despondency swept over Mashiro's whole body.Holding back the tears and not letting them flow out, because Liu Sen said that only weak and incompetent people would wipe tears all day long... But now, what else can I do besides crying?

"If you only have this ability, the position of the main palace will be taken away by my sister sooner or later."

The sudden appearance of a female voice disturbed Mashiro's gloomy mood, the pet girl raised her head blankly, and what she saw were smiling Yukinoshita Haruno and the talented forensic expert DR Fashion.

"The favor owed by my sister has to be repaid by me, my sister."

"Yes, my love for Police Officer Liu can break through the sky!"

"So... are you planning to do me a favor?"

Zhenbai asked some hastily.

"Probably that's what it means." Yukinoshita Yoshino shrugged, "The energy of Yukinoshita's family is still greater than you think, the police have been dismissed by me for a while, let's hurry up Keep investigating."

"First of all this." Yukinoshita Yono didn't care whether Mashiro could accept it or not, she took out a lot of bottles and jars, and then winked at DR Fashion.

"Oh! This is the lost chemical that Mr. Shizuka Hiratsuka said before!"

DR Fashion took over Yukinoshita Yono's talk.

"These bottles are all labeled with Sobugao's unique label, so there should be nothing wrong with it."

"And in my professional judgment, these chemicals together..."

"Gas-guzzling!"

Yukinoshita Yoshino replaced Liu Sen's previous job, and punched DR's fashionable nose bone who refused to speak properly.

"Stop beating—I won't be a slut again!" DR Fashion begged for mercy loudly, and then hurriedly said, "These chemicals are very similar to the formula of a pro-volatile agent."

"The so-called co-volatile agent is a substance that can increase the volatility of organic solvents. Organic solvents, gasoline, alcohol, and benzene solutions in our daily life are actually all of them."

"Then to what extent can it be enhanced?" Yukinoshita Yono asked.

"Then let's use gasoline as an example." Although DR Fashion is a bit perverted, he will be very serious when it comes to professional knowledge about forensics.

"Gasoline itself is already a very volatile substance. If you add these things, if you pour it on the ground, the gasoline will turn into a gaseous state within a minute and disperse in the air."

"Sister Yang Nai, thank you very much."

After DR Fashion finished explaining, Mashiro walked up to Yokino Yukinoshita and said seriously.

"Don't thank me, if you want to thank, thank that guy Liu Sen. No matter how you say it, he saved my sister back."

"Then what about me, Miss Shiina, don't you thank me?" DR Fashion interjected with excitement.

"No one will thank the pervert!"

Yukinoshita Haruno pulled DR's stylish ear and walked towards the murder scene.

"Xiao Zhenbai, let's go. We should rush over to investigate while the police have just withdrawn from the scene."

......

According to the requirements of DR fashion, the three people who entered the crime scene put on protective clothing, masks and gloves, not only to protect their own safety, but also to protect the fingerprints on the physical evidence from being destroyed.

Perhaps because of going deep underground, the temperature at the murder scene is a little lower than that on the ground, but the three of Zhenbai know that the low temperature is just a cover-up, and the raging flames hidden behind the iron gate took away a man not long ago. students' lives.

This iron door is the door leading to the small room where Hikigaya Hachiman was murdered.The rather old iron gate is already covered with rust.The violent explosion destroyed the lock on the iron door, but according to the police investigation, the structure of the iron door is quite stable, and it will automatically lock back, and it will take a lot of effort to break it with violence.

Pushing the door open and entering the small room, apart from DR Fashion who had already surveyed the scene, Yukinoshita Haruno and Mashiro were all stunned in place by coincidence.

It was the first time I came to this terrible place, and the suffocating burnt smell in the air has not dissipated.There is always a rather unpleasant feeling, both Mashiro and Yukinoshita Yono are quite sluggish.

Although I really don't want to look directly at it, but Mashiro knows that he has to do this-investigate Hikigaya Hachiman's body carefully, Mashiro told himself so.

The corpse was completely charred, not to mention the face, even the body shape was burnt beyond recognition.In some places, white bones can still be seen, and the shape is very terrifying.

Mashiro and Yukinoshita Yono carefully inspected the corpse, but for these two laymen, they still had to rely on DR's fashionable explanation.

"I took a brief look at the corpse before." DR Fashion explained in a timely manner, "I found that there were marks of blunt force on the skull of the corpse."

"It's just a pity...the corpse is destroyed like this, there is no way to extract DNA at all."

"The reason why the identity of the deceased can be determined is also based on the analysis of the unburned teeth."

"Is that so?" Yukinoshita Yono nodded, pretending to understand, "What is that?"

Yukinoshita Yoshino pointed to a plastic that looked burnt next to the corpse.

"That's a smartphone." DR Fashion replied, "It's just that it's burned so badly that it's hard to recognize."

"But you will be punished for using a mobile phone in Zongwu High School. Even I, who has graduated for so long, remember this. How can this person do it?"

Yukinoshita Yoshino doesn't know Hikigaya Hachiman at all, she just thinks that she regards the school rules as a guy with car exhaust, which seems to be quite individual.

It's a pity that this mobile phone has been burned, otherwise maybe we can get a lot of useful information from it.

"What is the corpse holding in its hand?"

Yukinoshita Yono's fingers continued to move, and moved to a bottle-shaped object held by the dead body.

The bottle looks like a thermos cup, although the shell is badly burned, but the structure seems to be intact.

"Why are you holding this... Could it be?"

Zhenbai, who had been silent since entering the murder scene, suddenly opened his mouth, recalling the science popularization of the milk tea shop owner and DR Fashion before, with a slight sense of uneasiness, the gloved Zhenbai twisted open the thermos bottle, and what fell out was actually . .....

A paper?A piece of paper torn from an exercise book?There seemed to be something written on the paper. Looking at the beautiful handwriting, it should be written by a girl.

The discovery in the thermos made Zhenbai a little disappointed, but she knew better that she couldn't be easily dejected now.

"Hmm... what is this thing?"

Zhenbai asked suspiciously, although it had been burnt to nothing, it could still be seen that it was a plastic product, and if you got closer, you could smell the obvious gasoline smell.

So what is the nature of this plastic product... This question is not difficult to answer——

Although it has been severely damaged and deformed, it is still obvious that this is the head of a plastic oil drum.

"Wait, perverted coroner..." Yukinoshita Yoshino asked suspiciously, "If this is an oil barrel..."

"I'm a watchman, not a coroner!"

DR Fashion retorted loudly, but after seeing Yukinoshita Yono's malicious eyes, he didn't dare to force him loudly.

"It was this barrel of oil that caused the fire... This is the thinking of Officer Megure and the others, and it is also a natural association that everyone will think of."

"And a key was found on the corpse. Although I don't know what the key is used for, I took a good photo of it."

Zhenbai turned out to be a photo handed to her by DR Fashion.

"It's similar to the one given to me by the director of the security department."

Zhenbai compared the key given to her by the director of the security department with the key in the photo, and found that the two are really similar.
