It had been determined that the hour referred to H, that is, the H-shaped school building, so the three of them went to the bottom of the sky corridor of the school building and began to watch.

"The next step is to walk through the history of Harukawa High School and look for the Iron Tree, do you know something?"

Qiu Hinako didn't know much about the history of Qingchuan High School, but she asked the right person, you know, Jiang Wentai was unexpectedly familiar with these useless knowledge.

"I know that."

Jiang Wentai replied playfully, his index finger pointed at his temple, and after a while, he snapped his fingers lightly.

"It's fifty-three years."

"Fifty-three years? Does this refer to the time when the school was founded?"

Qiu Hinako reacted, but didn't quite understand, what does it mean to walk through time? Fifty-three years from this place? Doesn't make sense, right? Then it's .......

"Harukawa High School was founded in 1957, and it is 53 years since then...... We're going to take fifty-three steps?"

Chen Yingjie also reacted quickly, the steps of walking through time are to convert time into steps, right?

「bingo！」

Jiang Wentai is very happy, because this idea is not wrong, the Qingchuan Festival is during the founding day of the school, so there must be some gimmick about the establishment of the school, right?

"Shall we take fifty-three steps, then?"

Chen Yingjie made a tentative suggestion, but how easy is this to say, to know how big this H is, and where to start? No one knows.

Qiu Yanzi and Jiang Wentai shook their heads, meaning that they still had to explain what this iron tree was.

"What does the Iron Tree represent? What does that mean?"

Qiu Yanzi didn't understand, there must be no iron tree in the school, and even if there were, it couldn't be the real iron tree, because this was not a guess, but a treasure hunt.

fell into thinking again, the three of them were silent for a while, and Chen Yingjie reacted the fastest to show excitement, as if she had a new idea.

"Well, can you change it to English? The iron tree is Cycas, so let's go to C or s?"

When Jiang Wentai heard this explanation, he felt very incredible, and looked at Chen Yingjie in disbelief.

"I didn't expect you to ......"

"What ...... you?"

Chen Yingjie didn't know what he wanted to say, could it be "so good, so good"? Or is it "so stupid, so stupid"? How can I say that my answer makes sense?

"You know this kind of English, huh?"

"Is this what should be sighed......

Chen Yingjie was very disappointed, so this method is problematic, she also found it herself, it is not ingenious at all, and it seems that except for herself, few people know that Tieshu is Cycas, right?

Once again, I fell into contemplation, everyone was a little at a loss, seeing that time was passing, would anyone already know the answer? And on your way to a treasure hunt? The competition is a bit fierce.

"Why don't we follow the school building and find fifty-three steps? You'll always find it."

Chen Yingjie suggested everyone in a stupid way.

"But Yingjie, this will not be a little troublesome."

Qiu Yanzi is not afraid of trouble, but he feels that the workload is too large and unrealistic.

"Actually...... It's not impossible."

Jiang Wentai suddenly had something to say, and the other two looked at him with some incomprehension, what did this mean? In the face of everyone's doubts, he explained with a smile.

"I mean, what do you define fifty-three steps?"

"How can you define it? Of course, it takes 53 steps......

Chen Yingjie understands that everyone's height and leg length are different, so how to decide this fifty-three steps?

"So there is a ruler, and that ruler is ......."

Qiu Hinzi also reacted, so it is so, it is not the fifty-three steps that I think, but the fifty-three steps that can be quantified!

"That's right, that's it, fifty-three tiles."

Jiang Wentai replied thoughtfully, if not, what the fifty-three steps are are are all the words of the family.

"The front and back of the school building are paved with tiles, the left and right sides are concrete, and directly in front of it is an open road, and although there are trees on both sides, it is impossible to walk 53 steps from H, so the only direction is ...... The back of the school building."

After Jiang Wentai's logical reasoning, such a conclusion was reached, which was very convincing, and Qiu Yanzi and Chen Yingjie agreed very much.

"Without further ado, let's go."

At the initiative of Qiu Yanzi, the three of them quickly went to the back of the teaching building, they often passed by here, went to the activity room of the school magazine, and did not find any iron trees, is it a mistake?

But when Jiang Wentai got there, he suddenly realized something, and pointed to a place behind the teaching building with some surprise.

"Isn't that the Iron Tree?"

"Huh? Isn't that a peach tree...... Although it does not bear peaches, it does not bloom peach blossoms...... Doesn't it bloom?"

Chen Yingjie suddenly realized the meaning of the iron tree.

"Yes, it's not that the iron tree doesn't bloom, it's just that the flowering conditions are harsh, and the time is short, so it's rare to see it bloom. In other words, the iron tree in the puzzle refers to the fact that it could have bloomed, but because of certain conditions, it could not bloom, so that people could not see the flowers."

The peach tree that Jiang Wentai pointed to is exactly like this, according to legend, it has not bloomed for several years, as the only peach tree in the school, it bears everyone's expectations, but it is not angry, and can only see unhealthy green leaves with holes.

"That tree is like this, because the planting area is small, there is only one, pollination is not successful, and there is also the concentration of rainy seasons in this area, too much water, coupled with the erosion of pests and diseases, resulting in this peach tree, which has not bloomed, so it is not too much to call it an iron tree."

"I see."

Qiu Yanzi nodded in a trance, Mr. Peachtree is really hard, the pressure is too great.

"It looks like the tree is going to be removed in a few days because it doesn't look aesthetically pleasing."

Chen Yingjie also knows this kind of thing, because the peach tree that does not bloom is still quite famous in this school that lacks big news.

"It's pitiful, it's not its fault, alas......

Qiu Yanzi sighed, which made the two of them puzzled, but they didn't show it, because they were children in the city......

"Then let's go treasure hunting."

The deeds of the peach tree should not be publicized, it is better to do the right thing, Jiang Wentai drew a horizontal line in his heart at the peach tree opposite, and then from the side of the teaching building, he took steps and walked on the floor tiles of about seventy centimeters in a square.

The three of them counted together.

"One, two, three, four...... Fifty-one, fifty-two, fifty-three!"

There was a "bang", and the touch of the feet and the ground was a little different, and all three of them felt it, which was a sign of loosening.

"It's this brick that usually feels like there's a problem......."

Chen Yingjie sighed, the three of them withdrew together, surrounding this brick, this brick has some problems, it can be easily revealed, and the reasoning club is quite willing to use it, it is really delicate.

Jiang Wentai squatted down and carefully moved the turn.

When the three of them saw what was inside the brick, their expressions brightened.
