Kindaichi of Kexue World

Chapter 159 My reasoning can't be wrong!

Chris was eventually locked in the warehouse.

He was also searched before he went in, and some hastily brought things were taken away, such as notebooks, pencils, etc., and even the keys to the cabin were taken away.

It is estimated that they are going to verify the invitation letter.

Kohei Homura ran away, and in the end he was the only one trapped.

Fortunately he ran away...

"Fortunately, you searched at the end, otherwise I don't know how to pass the news to you." Chris said.

"Okay! If you hadn't taken off your contact lenses when you went to the hot spring with me yesterday, even if you sent Miyuki a note, I wouldn't have believed you!" Back to Chris.

His invitation letter is indeed different from others, but the flaws are obvious. It is very difficult to type the word "wall" wrongly, but it proves that Chris was framed.

Someone as smart as Jin Tianyi must be able to see it.

At this time, Jin TianYiYi and Miyuki had entered the warehouse and secretly released Chris.

Miyuki took out the note that Chris had slipped into her hand when she pretended to fall.

In addition to the word "wall" that hinted at the flaws in the invitation letter, there was also a symbol on the note - Cu+O2↑℃.

"This should be the oxidation reaction of copper...but what does this mean?" Miyuki asked curiously.

"Let's not talk about this, what time is it?" Chris asked eagerly.

"It's a little after eleven now..." Miyuki looked at her watch.

"It's too late, let's talk as we walk!" Chris said.

On the way, Chris explained to Kindaichi and Miyuki why he was in a hurry.

When he was observing the black torii yesterday, he found that the black torii was not without decorations, but was corroded and almost invisible.

At that time, he thought that the nearby hot spring must contain acidic substances, coupled with high temperature, so the decoration here corroded much faster than the other two torii gates.

This special environment inspired Chris, maybe the torii gate was not like this?
Later, when the housekeeper Iwata Hidesaku talked about the red mountain boy statue, Chris understood.

"Red bird" really refers to the red torii as Kaneda guessed one by one, but the red torii has changed under special circumstances.

Copper and oxygen will react at high temperature and change into black copper oxide.

The ore used to make the Shantong statue is red and rich in copper. It is conceivable that this ore is easily oxidized and turns black when exposed to high temperatures.

In other words, the black torii is likely to be red originally.

This puzzle is actually not difficult to solve, but it's hard to think about it. For example, people like Miyuki didn't think about it even if they knew about the oxidation reaction.

Jin TianYi is just a simple scumbag who doesn't know the chemical formula.

"According to my research on ancient poems, the treasure should be hidden near the red torii gate, and the time when the treasure is opened is when the tide ebbs to its extreme. It is around [-]:[-], which is now!"

Chris stood next to the red torii and stared wide-eyed, looking for a place that might be the entrance to the treasure.

Kindaichi and Miyuki followed suit.

5 minute passed...
10 minute passed...
15 minute passed...

10 minutes passed...

The tide is starting to rise...
But nothing happened...
"How...how is it possible!" Chris couldn't believe his eyes.

"We can't wait any longer. It will be twelve o'clock in a while, and the hot spring water is about to erupt." Miyuki said.

It would be too dangerous to wait any longer, so the three of them had to go back home no matter how unwilling they were.

As the three of them walked back, Kaneda looked serious and thoughtful, Miyuki looked at the others worriedly, and Chris seemed to have been hit hard.

"Impossible? My reasoning should be correct... The tide has receded... The red torii gate... This is the time... What is the problem? Woolen cloth?"

Because he couldn't be discovered by others, Chris couldn't go back to the main house, nor could he go back to his cabin, so he had to follow him to Jin Tianyi's cabin.

The three of them sat around the table one by one, and the atmosphere was still very dull.

Jin Tian flipped through the materials he had collected before, and Chris was also muttering, not knowing what he was muttering, and even picked up a piece of paper to write and draw.

Miyuki looked worried, but didn't bother the two of them.

Jin Tianyi stopped first.

He scratched his head vigorously, looking distressed.

"Have you thought of anything?" Miyuki asked.

"I felt I had some inspiration because of the treasure thing, but there are still some things I can't figure out..."

At this moment, Chris also dropped the pen, and then covered his face in pain.

"Chris, are you okay?" Miyuki asked worriedly.

"Impossible? There is no problem with the time I calculated! How could it be possible not to open the door?"

"What time?" Jin Tianyi asked curiously.

"It's the time of the tide. I've calculated it. Today's low tide is about 10:[-] minutes. It can't be wrong. Why didn't [Magic Eye] rise?"

"Don't be discouraged, maybe we just went late, and when is the next time we will go again." Miyuki comforted.

"The next time I have to wait until tomorrow. The tide type of this island is a diurnal tide type, which means that the process of high tide and low tide has about twelve hours, which means that if you want to wait for the next low tide time, you have to wait again." About twelve hours."

"Then let's go again at [-]:[-] tomorrow, earlier this time..."

"Tomorrow's time will be different. The twelve hours I just mentioned refer to one day. As the date changes, the length of the tide will also change. Tomorrow's time will be about [-]:[-], which is exactly It’s hard to get through the hot springs and the red torii.”

"Then we'll go the day after tomorrow." Miyuki said.

"I'm afraid we won't last until the day after tomorrow!" Jin Tianyi said seriously: "The murderer may not even want to let us go... Wait a minute!"

Jin Tianyi stood up suddenly, startling Miyuki and Chris.

"You just said twelve hours refers to the time within a day, right?" Kinda asked one by one.

"Correct!"

"Then let me ask you a question. Today's low tide ebbs to the bottom at about 10:[-] minutes. What time was the high tide the night before and reached its peak?"

"About [-]:[-] p.m., of course."

"When was the low tide yesterday?"

"It was around 10:30 am."

"The high tide peaked around 10:30 the night before yesterday, right?"

"Correct!"

"In that case...that's it!" Kindaichi said with an expression of sudden realization.

"All the puzzles are solved!"
