If you cut the icicle horizontally and then put the two sections together to restore it, it should look like this.

But she didn't know what it meant.

In this case, the waterwheel will not move anyway, and no water will flow through the ditch.

In order to get rid of the cold, the two walked from the backyard through the atrium and returned indoors. Although it was not warm inside the haunted house, it was much better than outside.

Yui and Kirigiri walked along the corridor with their shoes in both hands.

"The secret room technique has been solved, but it seems that it will take a lot of time to accurately identify the murderer."

"How long will it take?"

"You need to question the testimonies of each person one by one... It will take three days to thoroughly investigate the relevant information, and it may be longer..."

"That won't be enough time!"

"Of course, we can't spend that long. If possible, it's best to just solve it theoretically, but since the time is limited, we can't worry about so much." Kirigiri said with a stern look and narrowed his eyes.

In addition to the four people, Sumu, Yagui, Du Ruo, and Shuijingshan, they also called several detectives to the sword dojo where the murder scene was located.

It is already two o'clock in the morning, and everyone gathered here is obviously tired. Among them, only Kyoko Kirigiri still maintains her calm expression as always.

"Excuse me...what did Mr. Ryuzoji say?"

A criminal police officer immediately and respectfully asked them to explain.

After all, the two of them are standing here as messengers of Ryuzoji Temple.

Naturally, Kyoko Kirigiri would not show any temper at this time. She said, "This case looks complicated, but it is actually a very simple secret room murder case."

"Is this Mr. Ryuzouji's opinion or yours?"

Kirigiri ignored the detective's question and continued.

"Both doors are sealed with rubber bands from the inside. It's almost impossible to open them. An adult man would have to use all his strength to pull outwards to create a small gap."

"Well, we put the knife into the gap and cut the rubber band before we went in." Sumu said.

"The question is why the murderer used rubber bands. Why didn't he use stronger chains or wires instead of rubber bands? What's the reason? As long as you think about it from here, the mystery of the secret room will be revealed soon."

"Hmm...then please show us how to do it in practice."

Several detectives walked away from the door, handing over the reins to Kirigiri.

The severed rubber bands were held in Kirigiri's hands, and now they had been tied again.

"This secret room made the witnesses mistakenly believe that the door was tightly closed, thus creating a perfect secret room. But in fact, this secret room was not tight and it made full use of the properties of the rubber bands."

"It's not a tight secret room, isn't it?"

The detectives nodded while holding pencils and writing furiously in their notebooks.

At the same time, the four suspected criminal visitors said nothing and quietly watched Kirigiri's every move.

"First of all, the murderer called Baizhou Cunwei to the sword dojo at any time after three o'clock in the afternoon. I don't know how he persuaded the victim. In short, when he was alone with Mr. Baizhou, he let the other party ingest

Take sleeping pills or drugs with anesthetic effects."
