Leila hastily dressed and headed to the Urseau’s mansion. When she arrived, there were already several people in his room.

"Fortunately, you came just in time, Detective Cassilia," said one of them.

"What in the world is going on? What should I do?" Cassilia asked.

Among them was Robert. Leila felt a little relieved when she saw his face. It was uncomfortable standing among unfamiliar faces.

"So, you are Detective Leila Cassilia. I've heard about you," the man said.

"It's a pleasure to meet you, Urseau," Leila replied.

Especially this man.

"You know who I am."

"Because Detective Urseau resembles you, I could recognize you right away."

His wolf-like eyes scanned me like a snake. Leila felt uncomfortable.

Fortunately, Robert spoke up.

"Detective Cassilia, can you decipher Detective Urseau now?"

"Decipher? What do you mean?"

"Haven't you heard the detailed explanation?"

"I came quickly because it was an urgent matter."

But it was not unexpected.

The only reason they called me to this place was for that one thing.

"If it's deciphering, then the 121 that attacked Detective Urseau hasn't completely disappeared and is still lingering."

Leila's face turned red with guilt.

"I may not know what's going on, but did I make a mistake in my response?"

Otherwise, there was no reason for such a situation to occur. She hung her head in shame.

"I understand. We'll start right away, so it would be best if everyone left."

"Just a moment. Detective Cassilia speaking."

Leila turned to the person who called her. He was wearing a white robe. It was a familiar face.

"He's the deer humanoid researcher we saw yesterday. He's collaborating with the investigation agency on 121."

This story has been taken without authorization. Report any sightings.

And he was also the one who examined Arcangelo yesterday.

"Could you hold my hand before we start decoding in earnest?"

"My hand?"

"Yes, Detective Urseau's hand."

He cast a strange spell on her. Leila grabbed Arcangelo's hand, which was already stretched out as he wished.

Then, she felt something flowing into him.

Beep, beep, beep. The wire in the monitor connected to his body moved up and down constantly. The most surprising thing was that he opened his eyes.

"Huh?"

"As expected."

The researcher said as if he had realized something. Leila turned her head to him.

"May I ask how this happened?"

She couldn't help but ask.

"As far as I know, the decoding of 121 involves injecting the frequencies of other humanoids into one's body, and to do so, they had to kiss or have sexual intercourse."

To Leila's follow-up question, the researcher grinned widely.

"That's right! That's why this situation is very interesting."

"Excuse me?"

Interesting? Her face looked weird. Robert's face was also very subtle.

"There he goes again."

Everyone heard it, but no one said anything. Urseau also closed his mouth with a worried look.

“Originally, Su-in couldn’t feel her own wavelength. Nevertheless, the current Detective Cassilia senses that her wavelength is dropping.”

“Uh... Is that so? But isn’t that the case with all of them when deciphering 121?”

“Why does that happen? Can we really assume that it's natural?”

“It’s not exactly wrong. But I don't think it's necessary right now.”

“Ah, let's just skip to the conclusion for now, shh!”

Robert covered the researcher's mouth and I explained.

“Without going into details, the conclusion is that the poison that Detective Urseau received is different from the previous ones.”

“Different?”

“Yes. It cannot be eliminated by injecting a different wavelength. It can only be put to sleep.”

Leila's eyes widened. She looked at Arcangelo, who was sitting up in no time.

“What the hell is this?”

Arcangelo was unusually silent. He seemed like a person with no mind.

“However, the danger has decreased. Once it's deactivated, it seems to fall asleep again even with much less wavelength than before.”

“That was my hypothesis!”

The researcher intervened with an excited face. Leila's face also became subtle. At that moment, Arcangelo spoke up.

“In short, it's a ticking time bomb.”

His impression was deeply frowned upon. Then, Leila noticed something strange. He was still holding my hand. I had already let go of my strength.

"It's hurting a bit."

He even held it stronger. She frowned slightly.

“You'll become a helpless, pathetic sight that might collapse again anytime. A loser, a ticking time bomb.

"Detective Urseau."

"You fit the part quite well."

Leila frowned and pointed at his hand with her finger.

"I don't know about that, but for now, let go of my hand and let's talk."

She seems a bit unhinged, should I hit her now? As he pondered this, finally, Arcangelo's gaze also turned toward them.
