I walked up to the small door and crouched down to place the gem in my hand into the groove in the door. The gem easily got stuck in the groove and merged with the small tree door, and with a soft sound, the tree door opened a crack.

I opened the door of the tree wide, and inside was a glowing white expanse, just like the door on the top floor of the color TV tower last time. I tried to reach into the door, but it didn't feel anything special, but it got stuck on my shoulder, and at this size, we couldn't get in, so we had to find another way to get in.

After checking, I got up from the ground and shook my head at the others, signaling that there was no way to go straight in.

"Can we get the kind of flower that makes us smaller the same way we got here?" Lin Ya hugged his arms and thought with a slight frown, "Let's use the method just now, walk a few steps to the place where the smaller flowers grow, and then walk a few steps back, isn't that okay?" ”

"I'm afraid not." Yu Pu shook his head, paused slightly, and then said, "I'd better try it first, wait a minute." ”

As he spoke, he took a few steps in the direction of the road, but this time his surroundings did not change as before, and when he stopped, we were still beside the giant tree.

"Sure enough, this won't work." Yu Pu said calmly, turning his head to Lin Ya and explaining, "What's special is this tree, not the space we walked through before, so that method should only be able to go back here, and not be used to reach other locations." ”

I looked at the small glowing door for a moment of helplessness, obviously the escape door was in front of me and had already opened, but we couldn't get in? This is an unfortunate thing.

"Then let's go back on, get to the rabbit and eat that flower, and then come back the way you did?" I thought of other solutions, "Now all the walls of thorns should be gone, and the rabbits won't attack us." ”

"I don't think the method you're talking about is feasible." Yu Pu shook his head again.

I was puzzled and asked, "Why?" Since we can't get there by shortcut, wouldn't we just go back there? ”

"I said that the space here is special, and it should be a form of space that is beyond the scope of our knowledge." Yu Pu stretched out his two index fingers as he spoke, drawing a line in the air, "If we use the analogy of what we already know, I would venture to guess that the space we walked in before was not a three-dimensional space, but a four-dimensional space. ”

"Four-dimensional space?" I frowned and tried to understand Yu Pu's thoughts, "The fourth dimension is time? ”

"Yes, it's time." Yu Pu nodded, "If the places we have walked in before are all in the same three-dimensional space, then it must be the fourth dimension - time that changes the environment." ”

"What does that mean?" Wolf Fang asked in a deep voice, although it seems to me that Wolf Fang knows a lot, but it seems to be similar to survival or combat knowledge, and he can't understand this kind of theory very well.

"There's a saying that you can't step into the same river twice." Yu Pu's face was expressionless, just calmly narrating, "That's what it means." ”

I felt a little pain in my head again, and when I raised my hand and pinched my eyebrows, I saw the puzzled gaze cast by the wolf fangs, and I knew that he still didn't understand, and was waiting for me to explain. And the other three people next to him were also confused. I understood what Yu Pu meant, and thought for a moment before explaining.

"Man cannot step into the same river twice, this sentence was said by a philosopher named Heraclitus, he means that the river of one second is different from the river of the next second, and only stepping into the river at the same time is regarded as stepping into the same river, but time is constantly passing, and there is no way for human beings to go back to the time that has passed, so they cannot step into the same river twice"

"I know this!" Fang Ruoxi interjected on the side, her face was a little timid, and after realizing that I didn't say anything because of her interruption, she hurriedly said, "The content of our high school politics is about the dialectical materialist movement that is eternal. ”

"Yes, that's right." I glanced at Fang Ruoxi lightly and didn't say anything to her, what problems she had are still unknown, and I'm not sure how to treat her at the moment, "This sentence is the same as our current situation, because although our environment and experience have changed before, the three-dimensional coordinates have not changed, and it is the time coordinates of the fourth dimension that triggered the change." In other words, we have walked through so many positions before, and we have actually walked through one point in time. ”

"All we can grasp is the change of three-dimensional coordinates, and there is no way to turn back time." I sighed, "So we probably won't be able to find that smaller flower anymore." ”

"And what will happen if we go back down this path?" Lin Ya asked, looking at his appearance, he still didn't understand after listening to my explanation.

"I don't know." Yu Pu shook his head and answered Lin Ya's question, "We don't know the exact laws of this four-dimensional space, and these are also our speculations, maybe if we keep moving forward, it may be possible to reach that position again, but it is more likely that we will encounter a new fairy tale and keep going." Until you find a practical solution, it's better not to do useless work. ”

"There must be something else." Wolf Fang said, turning to look at me, "In my experience, finding the key to open the door of escape is the hardest part of every room, and Earth Consciousness can't design a room where we can open the door but can't get out. There should be a very simple way, and on second thought, it should be a very simple way. ”

The easy way? I looked at Wolf Fang and blinked, hoping he would give me more hints, but he seemed to have only thought so much.

Is this something that can be easily thought of!?

"You mean to say that all the things we've been through before have happened here where we're standing now, so shouldn't that flower grow here too? But we can't pick it up? Chen Si sneered as he spoke, and waved his arm vigorously, "It's funny, we tried our best to risk our lives to open this broken door, but we couldn't go back because we couldn't travel through time to pick the broken flowers that grew under our feet?" Depend on! ”

Just under our feet, I looked at Chen Si and was slightly stunned, and her words made me feel as if I had been inspired by something.

Spend time in the fairy tale forest

I took a deep breath to make my logic clearer, assuming it was a game - in a way it really is - and now that we've killed the final boss and can clear the level right away, and there is only one kick left before the final Hay End, then there must be a hint for the last task to be completed, and this hint should appear after killing the final boss!

If there's anything like a hint, it's what the queen said to me! I suddenly remembered the answer the queen had given me—

"You have to know that this is a fairy tale forest, there is nothing impossible here, everything you want to happen can happen, you only need a reason."

Yes, the queen is right! Everything can happen in the same place where flowers grow perhaps!?

Thinking of this possibility, I ran straight around the trunk of the giant tree in one direction - yes! It must be so! This is where that kind of flower grows, so I just need a reason for it to appear!

Noticing my sudden move, the Wolf Fang shouted at me behind me, but I didn't respond to him, just bent on confirming my suspicions. After running a short distance around the trunk of the tree, a splash of blue caught my eye!

Flower! Blue flowers! I stopped, looked at the small sea of flowers in front of me, and couldn't help but smile. All it takes is one reason, such as a change of vision, and this flower will appear in front of us as I want!

Footsteps came from behind me, and I turned my head to see that it was Wolffang and the others chasing after me. Seeing this piece of the flower we were looking for, except for Yu Pu and Wolf Fang, everyone's face showed a happy expression. Fang Ruoxi and Chen Si cheered even more, and ran directly towards the sea of flowers.

Wolffang walked up to me, looked down at me slightly for two seconds, and smiled.

I thought he was going to say something to me, but he just smiled at me and didn't speak.

The wolf's gaze was very scorching, although there was no malice, but it made me feel a little uncomfortable, and my face turned red uncontrollably, "What's wrong?" ”

"Nothing." He whispered. "Well done."

You still need to say that! I coughed lightly and turned my head away, and the feeling of heat on my face made me know that my face must be as red as a monkey's butt now. I didn't want Wolf Fang to see my flushed face, so I only left him with a side face, and secretly rolled his eyes but couldn't help but snicker.

"Wolf Fang! Don't leave! ”

Hearing Lin Ya's voice, I turned my head, and Lin Ya seemed to be slightly stunned when he saw me, and then showed an extremely obscene smile. I rolled my eyes again, thinking that Lin Ya, an unserious weird man, must have misunderstood something again.

However, Lin Ya didn't say anything, just stretched out his hand and handed me and the wolf tooth a blue flower each, "Take it, let's go back to the door and eat, and then we can go out from here." The next goodbye is a week away, so rest and prepare. ”

Wolf Fang and I took the flower in silence, and after we took it, Lin Ya said again.

"Then I'll go back first, I miss my kitchen."

He laughed evilly, winked at me, and leaped past us, walking around the trunk of the tree in the direction of the door.

Seriously, I kind of want to hit him.
