"This shows that the specific location where the murderer shot was the utility room on the ninth floor."

Having said this, he concluded:

"According to this, the time of the incident was determined to be around 10:02."

"The scene of the crime is determined to be the utility room on the ninth floor."

"So, Matsuo-san, were you in the utility room on the ninth floor around 10:02?"

"Not here!"

Matsuo said with an ugly face:

"As I said, I never went there at night."

"I just went to the utility room once at noon, and went there to smoke a cigarette."

"Even if you can find some traces of me in the utility room..."

"There is no way to prove that I went to the utility room at 10:02, right?!"

He mustered up the courage to justify himself in this way.

But Asai Chengshi gave him a confident smile:

"of course can!"

"Mr. Matsuo, do you remember that you had the flu?"

"Then the saliva spots you left behind can also contain the flu virus in your body!"

"What, what?" Takashi Matsuo was puzzled when he heard that, "Influenza... virus?"

"How does the virus prove that I went to the utility room at 10:02?"

"It's simple—"

"Detecting Influenza Virus Activity."

Naruto Asai paused slightly, and said slowly:

"Viruses need living cells as vectors to survive."

"General viruses are exposed to dry air. Due to many factors such as water loss and temperature changes, the protein quickly loses its original structure, and even the entire envelope shell shatters and shatters."

"Influenza viruses have weaker external resistance and are quite sensitive to heat."

"Although the TV station building has central air-conditioning, the window in the utility room is always open, and the hot air from outside is pouring in, and the temperature is relatively high."

"According to the temperature in the utility room, after the influenza virus leaves the human body, even the most survivable influenza A virus can only survive for 2 hours."

"This..." Takashi Matsuo's expression changed.

Hearing this, he finally understood what the other party was talking about.

"If, as you said, you left the saliva spots in the utility room at noon, the virus in the saliva spots must have been inactivated by now."

"But, conversely, if active influenza virus can still be detected in the saliva plaques..."

Asai Chengshi said the answer:

"That means you have been to that utility room within the last two hours!"

"As for Mr. Matsuo, according to my interview, you start preparing for the evening program with the program group at 4 pm."

"Receive Mr. Lin and Ms. Mao Li at 7 o'clock, and then stay with them for 2 hours."

"The live broadcast started at 9 o'clock, ended at 10:20, and then went to the scene of the crime with everyone."

"That is to say, within the seven hours from 4 pm to now."

"The only time you are out of everyone's sight and you can go to the utility room—"

"Only at 10 o'clock, the 3-minute break of the live broadcast!"

As long as active virus can be detected in the saliva spots, it means that Matsuo has been in the utility room in the last two hours.

And during this time, even going back to 4 pm, the only time he was free to go to the utility room was those 3 minutes.

"In that case, it is easy to conclude—"

"As long as active influenza virus can be detected in saliva plaques, it means..."

"At about 10:02 when the crime happened, you were in the utility room on the ninth floor that was the scene of the crime!"

"This point seriously conflicts with your confession, which is enough to prove that you are the murderer!"

There was a different kind of brilliance in Asai's eyes.

Speaking of which, this was the first time he participated in the investigation of a case as a policeman.

Not long ago, what he thought about every day was how to kill people in a more subtle way.

Transforming from a vengeful demon to a righteous enforcer is an amazing feeling.

At the same time, it also made him feel a kind of light like being reborn.

"Now the saliva spot sample has been preserved by me on dry ice and sent to Mihua Hospital for virus testing."

"Then, Matsuo-san..."

"Let us look forward to the test results of virus activity!"

Narumi Asai looked at Matsuo with piercing eyes.

As for Takashi Matsuo, his face was ashen.

Chapter 165 The Promise With Zhibao

Takashi Matsuo never expected that this little flu he got would be the key to his exposure.

At this moment, facing Narumi Asai's piercing gaze, he was like a mouse stuck in a corner by a house cat, trembling with guilt.

"Mr. Matsuo, confess your guilt!"

Narumi Asai keenly captures the vulnerable side exposed by Takashi Matsuo.

He persuaded while the iron was hot:

"Maybe you still have a little fantasy that the test results will be beneficial to you."

"But, come to think of it, how likely is this?"

"If you plead guilty now, you can barely count yourself as a surrender, and you can appropriately reduce your sentence."

"Wait a few hours for the test results of virus activity to come out, and the evidence confirms that you are the murderer, and it will be too late for you to turn around."

"I…"

A thin layer of cold sweat oozed from Matsuo Takashi's forehead.

At this moment, his psychological defense completely collapsed.

And crashes are normal.

After all, compared with the criminals in this Kexue world who would kneel down and cry when the music played, Takashi Matsuo has been able to resist until now, which is considered to be a super-level performance.

"I..." He swallowed hard, and finally let out a long sigh:

"That's right, I killed Suwa Michihiko."

As soon as this remark came out, the police officers present breathed a sigh of relief.

They were finally able to call it a day and go home to sleep peacefully.

On the contrary, Mao Lilan's eyes were full of touching emotions, and she asked with some concern:

"why?"

"Didn't you say that you and Mr. Suwa have been good friends for half your life?"

Even though she has seen countless examples of friends, lovers, and family members fighting in the same room, Mao Lilan, who is naturally emotional, will still be moved by such a tragedy.

She couldn't help but asked:

"Since we are friends, why did we come to this point?"

"Because he betrayed me."

After saying this, Matsuo Takashi's face was filled with pain:

"The program "Perspective Japan Detective Agency" was planned and produced by Suwa and I, and worked together to manage it."

"It's like my child, it's my life's work."

"But now that the show is popular, he thinks I'm outdated and can't play anymore, and wants to 'optimize' me out."

"He ruined my dreams and made my life a joke!"

"Oh... you must not understand, right?"

"This kind of unresolvable hatred, so hateful that I want to kill someone."

As he said that, Takashi Matsuo sat down on the seat, and the police officers who surrounded him handcuffed himself:

Asai Chengshi took a deep breath, and slowly replied:

"No, I can understand your mood."

"And, I definitely understand it deeper than you."

"But Mr. Matsuo, you should have experienced it yourself..."

"Revenge will not save your life, it will only make your life fall into the abyss completely."

"This...maybe it's like this..."

Takashi Matsuo sighed lightly, his expression became somewhat relieved.

In this way, he obediently put on handcuffs and was escorted away by the police officers.

And looking at the back of the prisoner being escorted away, Asai Chengshi stopped and said nothing, with an extremely complicated expression.

"what happened?"
