We were surprised by the device we saw, and we didn't even know why it was here. "Teacher, is this what the diary says, what the old man left behind?" I looked at Teacher Xia Fan standing next to me with a puzzled face.

"I don't know."

The teacher stared at the device, turning his face to me, his expression suddenly confused. "At least I didn't hear Grandpa mention it." She approached the device, observing it as she spoke. "Of course, neither did Grandma."

She watched around the device and walked back to tell me. His voice was a little muffled, and his expression looked a little disappointed. "I think, either grandma doesn't know, or grandpa deliberately hides it from me."

After saying that, he went to the corner and moved a chair and sat down. Instantly, the floor couldn't help but make a "crunch" sound. At this time, the cicadas outside the window gradually became louder. Feeling unwilling, I approached the device again, reaching out to touch its edge. At the moment when the fingers were about to touch—

"I'd advise you not to touch it." At this time, Shion came over and grabbed my hand, and her expression became very serious. "Why?" I stared at her face with a puzzled look on my face. "We don't know how this device works right now, and if you touch it randomly, something terrible can happen......

"By that terrible thing, you mean?"

Suddenly, I couldn't help but ask a little nervously. The sounds are getting weird...... Shion slowly let go of my hand, took two steps back, lowered her head slightly, and thought very seriously. Then he slowly raised his head and looked me in the eyes with a very serious expression. "Like, death?"

Suddenly, I didn't know what kind of expression to show when she said her words......

"Won't it?" Instantly, it was as if there was a delay, and it took a few seconds for my expression to slowly start changing. "Anyway, it's right to be cautious. Especially when confronted with something we don't know. ”

"Because it saves you a lot of unnecessary dangers."

Shion stretched out a finger and said confidently. The voice became cheerful again. "It would be nice if there were instructions or something—" Izumi said in a somewhat deflated voice as he passed by me. Then, slowly look away from the device. He sat down in the place where Shion had just been......

The expression was also a little frustrated.

At this time, Teacher Xia Fan also sighed. Walked over to the device again, stretched out his right hand and tapped the middle with his fingertips. "It's right to be cautious, but I don't think grandpa can put a failed product here."

Then he turned his head and said to us. "Although he was very kind to me, my grandfather took research very seriously. I often lock myself in my room and am so busy that I almost forget to eat. ”

As she spoke, she reached out her left hand and tapped her fingertips on the left side where the middle meets the upper part.

"If 'that thing' in Grandpa's diary refers to this device, I think he must have come to some conclusion. Or maybe it's a big discovery to put it here, right? ”

As he spoke, Xia Fan walked to the side of the device near the window again, and then slowly squatted down, wanting to see what was different from just now. "I can't see clearly—" At this time, her voice couldn't help but be a little irritated. Because it was dark, there wasn't much light left from the windows after a few turns.

Before you know it, your face is almost touching the surface of the device. At this moment, the left hand seemed to touch something—unlike the otherwise flat touch, only this place seemed to feel a little sharp, and although the scope was not large, its surface was sunken inward.

The angle is not large, but it is clearly different from the surroundings.

"I found something interesting. Come and take a look—" Then, Teacher Xia Fan said confidently and beckoned to us.

"Is it a button?"

Lola crouched down next to me and pulled out a flashlight from the backpack she had brought.

"It does seem to be so." Through the light it emitted, we finally saw clearly what Mr. Xia Fan said about "interesting things". "I wonder what will happen if I press it?"

I looked at Izumi and Shion next to me, my expression was a little curious, and my voice couldn't help but be a little excited. "Then you can try it?" The moment the shoulders touched together, Shion turned her face to me, and said in a somewhat cold voice.

"Try it!"

Unwilling to be looked down upon by her, I immediately reached out and gently placed my finger on the rusty buttons all around. Then, press it hard! For a moment, we all stared at the device a little nervously, praying that it wouldn't change, and at the same time hoping that something would happen to it soon—

Such an inexplicable and contradictory sense of anxiety made my palms slowly begin to sweat. Then, as a sharp metallic sound slowly spread around, the upper part of the lid also shifted slightly in the direction of the window.

Suddenly, a lot of mist-like gas spilled from the edges and fell to the ground. Make a slight noise. Suddenly, we couldn't help but take a few steps back. But they still pass through the soles of their feet as if nothing happened.

"It's so cool!?"

Izumi was startled and immediately ran towards me.

I pushed him behind me against the wall, and it took me some time to calm myself down. It's just that the temperature in the house has dropped a lot by this time. The exhaled breath also turned white. At this point, the lid on the upper part stopped moving and began to slowly open upwards under our watchful eyes......

At the same time, a window appeared in front of him—a real-time video of the outside was playing. "What is this?" Shion turned her face to me in surprise, her eyes widening. "Don't ask me, I don't know why."

As I spoke, I turned to Mr. Xia Fan again and stared at him with a puzzled face. "Don't look at me, I don't know." Suddenly, she shrugged her shoulders quickly and said in a voice that seemed to be very depressed.

Just when we felt a little frustrated, the window in front of us gradually widened, and the whole picture slowly became clearer. The blurring of the edges is not as severe as it was at the beginning. — Then, something emerges from the corner of the frame......

"Grandpa?!"

The person who emerges from the corner of the frame is thin, honestly like a bamboo pole, wearing black square-rimmed glasses and a white coat. On the left side of the face, near the corner of the mouth, there is a mole. It's not conspicuous, but it's impossible to ignore.

"What? Grandfather? ”

Suddenly, I was stunned for a moment, a little unresponsive. His eyes turned several times between Teacher Xia Fan and the old man who suddenly appeared in front of him, his face full of surprise. "This is the teacher's grandfather?"

Then, I asked, pointing to the person in the frame.

"Yes."

"Well, did you finally find out?" Then, before I could react, the old man in the picture spoke to himself. "Honestly, that's commendable! Hahaha! ”

His voice was cheerful, not at all like that of an older person. "Looks like I have a good friend—" he said, turning his face to me and staring at me for a moment, his expression very curious. "Wait, grandpa—"

At this time, Xia Fan's voice was a little anxious. "They're not friends, they're my students, to be exact." Then, he explained very seriously. "Students? That is, are you a teacher now! ”

"yes......"

Although Xia Fan's expression was a little reluctant to speak, he quickly admitted it. "Grandpa, is everything I saw in my diary true?" Xia Fan came closer and asked again. "Do you think I'll write a lie in my diary?"

As a result, the other party asked back.

"And those were originally left on the premise that you would eventually find out." The person in front of him had a relaxed expression, but his voice was very serious. "In other words, is there really more than one world?" At this time, I couldn't help it anymore and walked next to Mr. Xia Fan...... Asked in a voice that drowned out her.

"That's right."

The person in the picture also answered quickly and confidently. "It's just that most people can see only one." Immediately afterwards, I wanted to continue asking, but was interrupted by Mr. Xia Fan.

"Don't worry, speak slowly."

Then, as if to comfort me, he patted me on the shoulder. He handed me another bottle of water—and as I reached out and unscrewed the cap, and drank it several times, he explained to me what I had just asked...... And, of course, everything that happened during this time.

"From another world? Are you sure?

Xia Fan just wanted to say his opinion, but was interrupted after a while—"Of course I believe it, you don't need to explain, Xiao Xia." This made Xia Fan breathe a sigh of relief. I'm still thinking, grandpa, what am I going to do if you don't believe me......"

"It can't be like this, can it? How stubborn are you thinking about me......"

After speaking, he seemed to be a little depressed and laughed first, which also made Xia Fan feel very embarrassed. Listening to such a conversation, we could only try not to laugh out loud. "Now that he wants to go back, what should he do? Grandpa, you know what? ”

The man in the picture thought for a moment, then looked up at us again, "Isn't the answer behind you?" Then he reached out and pointed to the device behind him. Just get in there. ”
