There is only one light on the cement ceiling and nothing else.

This time the 'Black Challenge' approach to dealing with detectives is very comprehensive.

Imprisoning the detective in a closed environment and holding an auction every day at a slow pace can not only deprive him of his 'detective power', but also delay it until the end of time. This must be the opponent's purpose.

In the "Black Challenge", if the prisoner wants to win, he can only evade the detective's identification.

However, this does not mean that the prisoner will really escape, but that the detective will be trapped in the maze of thinking within the stipulated 168 hours. This is the way to win.

The finished product created on this basis is this ‘Black Challenge’.

"I said, Sister Yu, there is another side."

Kirigiri looked down at the bespectacled girl lying on the bed and shook her hair slightly.

"Ah, sorry, sorry."

May Yujie stood up and continued braiding her hair.

"Rather than trying to win at the auction, we are probably better suited to solving the case."

Kirikiri said this.

However, the other girl was also confused about the case.

She is really not suitable to be a detective.

When the two returned to the lobby, several people in the waiting area had disappeared.

The only two women sleeping on the sofa were Mifune and Yazuru, and none of the male compatriots were there.

Nanamimura, Sawada, Toriyao, and Shinsen sat in a circle in the cafeteria to eat. It felt a bit like having a picnic, and it was actually a bit warm.

If it weren't for this current situation, mealtime would have been a happy time.

However, each of them had the same haggard look on their face, even Sawada, who usually had a bad mouth.

"Hey, I'm really not used to sleeping on the sofa here. Oh, where were you just now?"

Zetian complained at first, then noticed them and said.

"Have a rest in the room upstairs."

"You should eat your food now before talking."

Toriyao said as he munched on the packaged rice.

After the night time period ended, everyone was indeed relieved.

Although Uzuki Yuyue wanted to discuss with Nanamura how to deal with it in the future, she never found a chance to be alone with him, so she had to give up and return to the hall.

The two of them took dry food and water and returned to Room 302. For them, they still felt most at ease here.

They had a tasteless meal together in a secret room that was so quiet that there was no sound at all.

Then they sat side by side on the bed and began to spend this idle time.

The two of them seemed to have known each other many years ago, sharing this silence as if they had a tacit understanding.

Probably because they had already experienced life-threatening situations together, Uzuki Yuyue couldn't help but feel that being with Kirigiri was a natural thing.

In fact, the relationship between the two of them over the past month can be said to be very wonderful and profound.

Therefore--

Perhaps now, she thought, it was necessary to learn about the things she least wanted to talk about.

"Sister Kirigiri."

"What's the matter, sister-in-law?"

"About your father..."

Her eyes instantly became more serious.

However, as expected of Kyoko Kirigiri, she remained expressionless and did not show any wavering.
