The Thorin main hub should be the most special of all the magic network main hubs in the empire - this is not only because its crystal array is built on the top of the tree, but also because the "living hub carrier" of Belltila uses the unique biological characteristics of the Thorin giant tree to make a bold transformation of the entire hub. She has made the originally cold steel and crystal cleverly merged into the structure of the giant tree, and her "design" is everywhere on the canopy of this giant tree.

Margarita was guided by Belltila to the area where the crystal array was located. The metal devices supporting the crystal array were deeply implanted into the giant trees. A large number of "pipes" with wooden structures and vines extended from the layers of branches and merged with the base of the crystal array. With a clamor, Margarita saw a "ground" near the base open. The leaves that looked neat and dense shaking retreated to the sides, revealing an inclined downward staircase, which seemed to lead to a deep place.

Although wrapped in layers of leaves and branches, the passage is not dim. A large number of glowing flowers and leaves and thin vines droop from the "walls" on both sides of the passage, illuminating the "small world" located in the canopy like lights.

"This is my 'learning room'. I built it in my body to make it easier to use," Belltila said to Margarita, and had already taken the lead in walking forward. "Please follow me - pay attention to the stairs under my feet. This step is a bit steep. I'm thinking about how to re-grow this part."

"It's really... clever," Margarita followed the other party's "footsteps" and led several technicians and accompanying soldiers into the "secret space" that belonged to Belltila. She looked at the luminous plants on the leaves on both sides and the stairs and corridors that were skillfully grown, and couldn't help but sigh, "I didn't expect you to have such creativity, Ms. Belltila."

"... Actually, I almost forgot that I have such creativity," Belltila's steps seemed to pause for a moment, and then continued to walk forward. "Curiosity, creativity, learning new things, observing the world... I have discarded a lot of things, but recently I'm trying to get them back."

While speaking, they had already walked through the slightly steep stairs and entered a rather wide space.

This is a roughly ellipsoidal "world in the tree", Margarita swore that even in her most imaginative dream, she had never seen such a strange but wonderful scene-

The solid wooden shell and support columns support the here, and countless green leaves and vine walls form the walls, floors and roofs of this elliptical space, and countless luminous plants—including flowers and hanging mycelium—provides lighting here, making it look like a brightly lit plant cave. And in this "hole", Margarita saw many things that humans cannot understand, including luminous vines distributed along the ground, some shiny vines hanging on nearby leaves walls, like some kind of cultivation sacs, some wooden, layered platforms, and the most eye-catching one is the most central...a structure in the entire space.

It was a huge sac that drooped from the ceiling. About dozens of vines and tubular tissues of varying thicknesses extended from the top of the sac. The entire sac is like a brown-red bag, which seems to be filled with some kind of liquid emitting a shimmer. As time goes by, some thinner "films" on the sac are still pulsing slightly, and something like a blood vessel is changing lightly and darkly.

It is a bit disturbing, but it also has a mysterious attraction. Its style is obviously related to the biochemical technology of the end of everything, but it does not have that bloody and crazy feeling.

"I haven't let anyone come here," Belltila said to Margarita. "As you can see, this is a place built according to my 'survival mode', and only I can use the things here. By the way, I shouldn't be considered a 'black', right? I didn't occupy any public resources, I just did some research here - I'm also a druid after all."

"Uh...I don't think this is a violation," Margarita thought carefully for a long time before organizing the language. "Strictly speaking... this belongs to your own 'physiological structure adjustment'. I think the imperial law cannot stipulate how you should grow..."

As he said that, the female general of the Empire seemed to feel that the current topic was a bit too brain-burning, so he waved his hand before the topic became even more weird: "We won't discuss these - Ms. Belltila, you mentioned just now that you analyzed the clues from the signal. Is this related to this 'secret base'?"

"Oh, of course, because the clues were developed here." Belltila nodded and led everyone to a bud in the ellipsoidal space. As Margarita and others approached, the bud, which was one-person tall, suddenly unfolded on its own. The originally curled green leaves stretched open, revealing its pure white inner wall.

"What is this?" Margarita frowned and asked curiously.

"It's just some trick that can be used to present the picture - for me, it's easier to directly control plants than to control magic net crystals," Belltila said casually, "This is just an irrelevant detail. What I want to show you... this."

While she was talking, she communicated with the plant structure in front of her. Margarita looked curiously, and then was surprised to see that dark green traces suddenly appeared on the inner wall of the pure white leaves.

"Since I received the strange signal last time, I have been thinking about what those signals mean - scholars have used many ways to crack it, including passwords, code words, converted into sounds, and converted into 'alphabet'... I also used many methods, but all of them failed. There seemed to be no logic in those short tremors. They did not correspond to some codebooks, nor did they have numerical rules, and after they were converted into sounds, there was only noise... So in the end I suddenly had an idea: Maybe these tremors do not involve passwords? Maybe they are some... simpler things?"

While telling the various attempts he had made, Belltila adjusted the lines that emerged on the blade and outlined more details before Margarita's eyes.

"...I used a very simple method that no one tried: draw the tremor directly. You see, when a strong tremor appears, leave a dot - like an ink dot, very small; then weak tremor or blank noise, then leave it blank. If the duration of a tremor is regarded as a "grid", then how long the weak tremor and white noise last, leave it to a blank...

"Then here, it's very important. It took me a long time to figure out how to deal with the changes here - in the signals we receive, a very short and very sharp waveform appears every other period. I initially thought it also represents some kind of 'line', but in the end I realized that it means...change a line.

"In the same way, we have also received several other very short and sharp waveforms, which each have their own meanings, and are used to position the subsequent 'dots' to a specific relative position in the previous paragraph..."

On the blades, there are more and more marks made of magic. According to the ideas mentioned by Belltila, the mysterious signal "listening" by the Solin Hub is rapidly transforming into a pattern composed of dots and blanks. At this time, Margarita is almost certain that Belltila's idea is correct!

Because those dots are not arranged randomly, their arrangement is taking neat and regular shapes!

"What is this?" Finally, a technician standing behind Margarita couldn't help speaking. The middle-aged man in a magic technician's robe stared at the "dot diagram" presented on the leaves, and screamed in surprise, "This..."

"A square, the square formed by connecting dots into lines, is very... regular, with the number of dots on each side exactly the same." Belltila said, and as she spoke, the dark green pattern imprinted on the leaves was still extending.

Those eye-catching dots have been connected to the square, but it is obvious that this is not all - there are still new dots emerging in the blank area next to the square, and are very obviously arranged in lines and combined into patterns!

Margarita and several entourage members all stared at it with wide eyes, guessing what it would eventually take, but after a few seconds, it all suddenly stopped.

The subsequent dots only formed a short line segment and ended abruptly.

"What about the follow-up?" Margarita couldn't help but look up and asked, "Why is it gone?"

"The signal behind was interrupted," Belltila spread his hands, "I recorded so much. You must know that using these tremors to record graphics is very, very low. We may have to record uninterrupted signals for a long time to fully draw this thing-but the signal I received was only ten minutes.

"...Damn..." Margarita couldn't help but mutter a little unnatural word, and then showed a thoughtful look, "So the nature of these signals..."

"It should be a picture, and what we see is probably only part of it - it is unknown how large it is, and its significance and the sender are completely a mystery," Belltila spreads his hands very humanely and shakes his head. "I even suspect that this is a drawing, of course it's just a guess - after all, there are too few parts that can be seen."

"Abstract, now we can basically be sure that this thing cannot be a 'natural phenomenon'," Margarita took a deep breath. "No matter who is doing this, there is an existence that has been sending us a picture continuously--or maybe not to us deliberately, but an indiscriminate broadcast, but just happened to be captured by our crystal array. In any case, this matter must be reported to the capital immediately."

"Of course," Belltila nodded, "This is very unusual. Think about the Internet whistling incident that happened not long ago... there are more and more unsettling things in this world."

"Well... Speaking of which, when did you discover these rules?" Margarita suddenly glanced at Belltila, with a curious look on her face.

"It was only a few hours ago," Bellti pulled the corner of his mouth, and seemed to have a smile. "Luck is the majority - the idea that came to my mind does not conform to the normal password cracking rules, it can only be said that it made me lucky to bump into it."

"That's still a remarkable result," Margarita praised sincerely, then couldn't help but turn her head and her eyes fell on the sac in the center of the ellipsoid space. "Actually, I've wanted to ask since I just now, what is this thing... for?"

There are many weird things in this ellipsoid space, but most of them are at least consistent with the characteristics of common things such as vines, flowers, plants, branches and leaves. The only thing that is the sac hanging in the center of the space is so weird that it is hard to ignore. Margarita has attracted her attention since she came in, but she was embarrassed to ask because of her official business. At this time, after the main talks, she finally couldn't help but speak.

What is the former minister who died in the past... in her "private research room"?

Hearing Margarita's inquiry, there was no strange look on Belltila's face (it was not easy to express her expression mainly because of the plant-based face), but her tone brought a hint of pride: "That is my optimization and supplement to myself. This time I was able to successfully crack the clues in the signal, thanks to the assistance of this thing. If you want to see it, I can open the outside capsule, but the things inside may have some visual impact on ordinary people... You must be mentally prepared."

Margarita immediately smiled and said confidently: "Of course - we are all specially trained and will not be shocked when encountering any situation. You can turn it on to satisfy our curiosity."

Bell pulled his head and waved it lightly. A squirming and rustling sound suddenly came from the sac located in the center of the "room". Then many neatly arranged cracks appeared on the surface of the brown-red sac. The entire wrapping structure bloomed around like a petal, revealing the transparent oval inner shell inside, the translucent nutrient solution inside the shell, and the huge and amazing biological tissue soaked in the nutrient solution.

It turned out to be a brain! A "synthetic brain" soaked in nutrient solution is nearly one person's taller than a person!

Margarita, the specially trained Imperial officer, widened her eyes the moment she saw that thing, and then she felt her hair slightly standing up: "This... what is this!?"

"I created a brain for myself - try to imitate the human brain, of course there is something wrong with the size... I didn't want to make it so big at first." Belltila said with an expression that was unchanged, as if it was just a trivial matter.

Margarita felt that her thinking could no longer match the vegetative person in front of her. When she asked questions again, her head was dizzy: "How did you think of creating a brain for yourself?"

Belltila thought carefully this time and explained to the other party patiently: "After becoming a plant, I found that my way of thinking is also moving closer to the direction of the plant every day. Recently, I have even stood here like a real tree. I don't want to do anything except bask in the sun and shake the leaves in the wind... I'm worried about this situation, so I created a brain for myself to help stabilize my cognition as a 'person'. As for the improvement of logical thinking and association ability brought by this brain... it is actually an unexpected gain."
