Ahri took out a completely rusted tin box from the room, and she carefully placed it on the table, as if it could be easily broken.

Diligence and I both looked at the tin box with curiosity, and through the gap in the rust, we could see a faint translucent red. Perhaps a long, long time ago, it was also an unusually delicate, unusually beautiful box.

Ahri gently pressed her hands against the edge of the lid, took a deep breath, and slowly lifted the lid upwards. Even though Ahri's movements were already very slow, there was a screeching sound on the tin box.

With a "clang", the lid was completely opened, and a long-standing smell came to my nose, which made me feel like I was in a trance. Diligent slapped a hand on my shoulder, and I suddenly came back to my senses.

"The pictures you want are here. Ahri said with a smile.

When I took a closer look with Qinqin, we saw that the photos inside were divided into several piles, and they were all wrapped in fine brown paper. Diligent picked up a bundle casually and carefully untied the knots on it.

Somehow, the knot was tied very strongly. The diligence has used all the strength of the whole body, but the knot still does not move. And as if against him, the harder he pushed, the tighter the knot became.

"Be diligent, don't push so hard, the photos inside are about to be crumpled by you. I said worriedly.

"Whew...... Then you come!" he handed me the bundle of photographs, and then slumped in his chair, gasping for air one after another, "I am diligent and famous, and I am afraid that I will lose on this knot!"

"Don't exaggerate it, maybe it's because the knot is so old that it sticks together for a while. ”

"Let me rest for a moment. Diligent closed his eyes and adjusted his breathing.

Seeing him like this, I couldn't help but want to laugh. But in order not to break his pride, it took a lot of effort to suppress the urge to laugh.

At this time, Ahri saw that we were holding the photo and couldn't open it for a long time, so she was a little anxious for a while. But maybe she didn't want to rush us, so she had to ask in a low voice.

"Little girl, can you open it?"

"Ah, Ahri, I'm sorry, I'll open it for you when I'm in Xi'an. ”

I held the bundle in the palm of my hand, looked carefully at the structure of the knot, and analyzed the direction of the two ends of the rope. At first, I thought it was just an ordinary knot. But when I looked at it seriously, I suddenly chuckled in my heart.

How is this knot tied the same as what Lao Xu taught me?

I immediately frowned and stared at Ahri. She was startled by my gaze and instantly withdrew her hands into her arms.

"Ahri, can you tell me who tied this knot for you?"

"Who tied it up? Why did you suddenly ask this question?"

"The way this knot is tied is the same as what Lao Xu taught me! From the outside, I thought there was only one knot. But in fact, there is still one hidden inside! If you untie the rope in the usual way, the knot inside will become tighter and tighter, until it is so tight that it can no longer be untied. ”

"Huh?" Qin Qin was also stunned for a while, "You mean, this knot has something to do with Brother Xu?"

"That's right, Ahri, can you remember? Who tied it for you?"

Under my questioning, Ahri lowered his head aggrievedly for a while. She thought about it, but after a long time, she still didn't remember.

At this moment, her body suddenly writhed violently. The attitude of resignation immediately became high. He put his hands on his waist and said confidently.

"I remember!" shouted Ali, "the one who took care of you all day!"

"Is it really Old Xu?!" I cried out in disbelief.

"Yes, yes, he seems to be surnamed Xu! He, he often comes to our house to collect vegetables, and everyone gets acquainted with each other!"

When Ali mentioned this, I finally remembered. At that time, Lao Xu also said that the vegetables grown by Ali and Ahri were very popular with the people of Greedy Town, so they would often come to their house to collect vegetables.

"Then why did he tie you up with a picture?"

"Well, it's actually very simple. I remember there was something new in town that day, it seemed to be called ...... There's a new thing, and Ahri and I are fiddling around with it in the yard. At this time, we happened to meet him to collect the food, so we asked him to take a few photos for us. ”

"After I got the photo, I saw that I was in the photo, I was really old, not as handsome as before. At this time, he said that he wanted to see what I looked like when I was younger, so that he could open his eyes. So, we took him into the house and showed him the pictures we had taken when we were younger. ”

"Soon, he'll be done. We are also very satisfied, and there are people who listen to us share the things of our youth. At this time, he said that these photos are very precious and cannot be put casually, otherwise they will get wet. So, he took a few pieces of brown paper from the car, and then separated the photos from the old and new, and tied them up. ”

Hearing what was going on, I nodded as if I didn't understand. But after a while, I felt like I didn't understand anything.

"Is there a difference between a camera and a camera?" I asked, looking back at Diligently, curious.

Diligent rubbed his temples, perhaps because he had invented so many intelligent machines that he couldn't remember which one it was for a while. But when Ali took out a palm-sized machine from a dusty box, Diligence immediately remembered it.

"That's it! Joan, the camera only records that moment, but the picture taken by the phonogram can record the events of the second twenty seconds after that moment. ”

"But aren't all photos freeze-frame?" Diligence smiled slightly, and I immediately understood, and immediately said in surprise, "No, will the photo move?"

"That's right, it moves. ”

"It's so magical, then I'll untie the knot now. ”

It's not impossible to say that the rope is separated directly, but if you do that, it will make the knot meaningless. Moreover, it will also make people lose the sense of accomplishment after unlocking.

I held the bundle of photos in one hand, and replayed in my mind the process of Lao Xu teaching me to untie the rope, how he did it, I did it. But I'm not as familiar with it as he is after all, and if I let him solve it, it may only be a matter of two or three seconds.

But for me, it took three or four minutes.

As soon as the rope was scattered, I quickly dismantled the vellum paper. The first thing that surprised me was not the contents of the photos, but the fact that they were so well preserved. At first glance, it looks like new.

"Ah, it's finally unraveled. Ahri came out again, and there was a look of excitement on her face.

"No, it's that simple!" said Qinqin very helplessly.

"Diligent, it seems that there are still things in this world that you don't know. ”

I teased him, but unexpectedly, he pouted and replied with a nonchalant expression.

"What's strange about this, there is a specialization in the art industry. ”

"What does it mean that there is a specialization in the art industry?"

"Hah, it seems, there's something you don't know!" he spread his hand and shook his head with a smile.

And just as I was arguing with him, Ahri pulled a picture out of my palm. She one

When I saw that photo, I immediately laughed. But in her laughter, she didn't just laugh, there seemed to be sadness.

I stopped talking for a moment and looked at Ahri. The moment she looked up, I could clearly see two flashes of light in her eyes.

I heard it right, I didn't read it wrong, it was her tears.

"Ahri, what's that picture?" I asked worriedly.

The corners of Ahri's mouth trembled, and he handed the photo in front of me. I looked down and saw that the photo had been taken in the yard. Directly in the middle, stood two elderly men.

One is an old grandmother with her hair coiled up and a silk scarf. She wore her hair coiled, crutches, and a little hunchbacked. Although it seemed that her movement was a little inconvenient, a bright and kind smile appeared on her face. This smile made her feel a little more abruptly girlish.

Next to her was an old man with a shaved head and shirtless upper body. With his hands on his waist, he squinted at the sky with his head held high. His face obviously did not have the kindness that an old man should have, but put on a fierce expression of wanting to collect debts. It's a little scary just to look at it.

"Is this you?" I exclaimed.

"That's right, it's our ......"

I looked at her smile on the photo, and then compared it with the smile she is now making with Gu Chengzi's body, it is really very similar. But after all, it was Gu Chengzi's facial features, and it always made people feel a little out of the way after looking at it for a long time.

Diligent also stood next to me, frowned, and looked at the photo earnestly.

"When was this picture taken?" he asked calmly.

"That's the day, the day Xiao Xu came to collect the vegetables. ”

When he heard this, his expression became more solemn. He stared at the picture for dozens of seconds, and the atmosphere in the room stood still with him for dozens of seconds.

The clock on the wall had actually stopped a long time ago, probably because it was so quiet that I could hear the sound of seconds moving.

Suddenly, Diligent Brow's brow exploded, and he clenched his hands into fists and slammed a vicious fist on the table. Fortunately, the table was made of solid wood, but he had hammered a dent.

"What's wrong?" I asked, nervous and worried.

"I ...... Finally understand what went wrong!"

"Where?"

"Look at the background of the picture!

I took a closer look, and then I realized that behind Ali and Ahri was the same greenhouse we saw today.

But what's wrong with that?

I scanned every corner of that photo and didn't find anything wrong. And when I finally focused on Ali, I realized that this photo was different.

He blinked!

"This is a picture taken by a photograph?"

"Yes, I remember back then, we were more motionless than anyone else. In the end, it was the old man who lost, hehe. ”

"I see...... However, diligence, this is no problem, it's just a couple competition. ”

"No, you should pay attention to that greenhouse. He said coldly.

That's when I focused my attention on the greenhouse. Since I missed the end, I had to watch it again.

I waited for a long time, and at the moment Ali blinked, I instantly focused.

I saw that in the greenhouse, there was steam, and it should be watering the vegetables inside. But suddenly, a small beam of lightning, from left to right, quickly penetrated the entire greenhouse.

"Electricity!"
