They never noticed that there was a water wheel here because it was too dark.

The water in the ditch passes through the bamboo forest and finally seems to flow to the bottom of the cliff.

However, in the severe cold weather of late winter, the water turned into ice at the bottom of the cliff, and the waterwheel became completely stationary. It was covered with thick icicles. Judging from the size of the icicles, this waterwheel should

It has been completely frozen for a whole winter.

"Just in case, let's go inside the cabin and have a look."

Kirigiri narrowed his eyes against the wind and said.

"Hey...what's in there?"

“It’s just because I don’t know that I want to go and take a look.”

The two of them huddled together and walked to the waterwheel hut. The entrance was on the opposite side of the ditch and they had to follow the small bridge above.

But you don’t have to follow the rules so much. The ditch is only one meter wide at most, so it’s easy to jump over it.

Late at night, in the darkness, the thatched-roof watermill hut beside the bamboo forest makes people feel that something will pop up at any time.

"There won't be a killer or other dirty things suddenly jumping out of the hut...?"

"Don't remind me of bad things, although I'm not afraid either."

Mist cut surface said without changing his expression.

The two slowly opened the old wooden door of the waterwheel hut, and Yue cautiously waved the flashlight as a weapon a few times, illuminating the inside of the hut.

Apart from the water-driven stone mortar in the center of the room, there were only shovels and other gardening tools piled in the corner of the room.

There's really nothing that feels dangerous.

However, there was something in it that made both of them pay attention immediately.

It was a jack, like a big spring, used to jack up the car when changing its tires.

Kirigiri dragged it out from the corner. The thing was not heavy and she could move it with her strength.

Generally speaking, jacks are placed in places like the trunk of cars in case they are needed in case of emergencies, but even if they are placed in this cabin, it is not very suspicious.

"Have you thought of something, Sister Kirigiri?"

"Well, this should come in handy."

She walked out of the cabin holding the jack in one hand.

Next, start inspecting the water tanker.

"Sure enough, it's a bit unusual." Yuu put his cold fingers to his mouth and breathed, leaning closely against Kirigiri, "Snow, water wheel and Japanese sword, these are the three major elements of a physical trick."

"...Really?" Kyoko Kirigiri was of course not interested in this. "Not to mention this, look, that icicle is so big."

"Do you want it? Then I'll take off the biggest one for you."

"I do not want it."

"Why? I'll take the second largest icicle so we can play with it."

"No." Kirigiri shook his head, "Icicles are important evidence."

"Eh...Icicle?"

"yes."

Kirigiri showed his usual proud expression.

Maybe she thought she didn't show her feelings, but it was actually written all over her face.

"Sister Xiangzi, have you solved the mystery of the secret room?"

"Well, the answer is already obvious." She said calmly.

Although both of them saw the same things, May Yujie still couldn't figure out the east, west, north, and south at all.

She is obviously the protagonist as a detective.

"If you look carefully at the icicles, you should be able to see a horizontal white line inside the ice, like a crack."

"Ah, it's true."

"This is strong evidence to prove the criminal methods."
