"It's eerie here," Hilda said, clasping her hands to her chest. After passing through a short hallway, everyone is now flying together on a cube towards the heart of Laputa.

However, the core of Sky City is completely different from the garden above, and it is not as sunny and full of life as the buildings above. Rather, it was a huge dimly lit space, and the whole space was very empty, except for some cube stones carved with patterns suspended in the space.

In addition, the walls around the entire space are made of such stones, neatly arranged. It's like a printing plate that is arranged during movable type printing. There are only one or two square gaps in a few places, and judging by the size and shape of the gaps, they should be left behind by the stones that are now suspended in the center of the space after flying out.

The cube beneath their feet descended until it reached a corner at the bottom of the space. Ryan used the power of the Rose Mother to summon the illusion of the pendant again, and a stone slab next to it disappeared, revealing a door.

Once everyone walks through the door, the ground moves down like an elevator. At this time, the surrounding environment is no longer pitch black, but revealing stripes of blue light, which is full of science and technology.

"Where we are now has a strong magical defense and extremely complex magical reactions. "I think this place should only be allowed to enter this place even at the height of this city in the sky. ”

"This is probably what my grandmother told me about the center of control that only the Laputa royal family can reach. When she arrived at this place, Sida also recalled some things related to this place.

"How long has it been since no one came to this place, and it feels like the whole space is taken over by tree roots. Baloo complained loudly, and after falling to the bottom, the door in front of him opened, but an arm-thick tree root blocked the door and made it impossible for everyone to get out of the elevator.

"Don't worry," Ryan said and reached out to touch the roots of the tree and began to communicate, and soon the roots of the tree seemed to come to life. Except for the roots of the trees that stood in front of them. All the tree roots that would hinder people's movement in the corridor outside the elevator have been moved to the side, forming a paved path to the main control room.

"Wow, that's amazing, is this the power of magic?" said Baru and Hilda in a whisper at the same time, and Ryan stepped out of the elevator and said, "Alright, now you two hurry up." It's not just the power of magic, but to do it to my level, you need to have a deep understanding of nature and a harmonious coexistence with the natural world. ”

"Sounds amazing. Balu shrugged his shoulders and pulled Hilda after him, and they followed the cleared path through a narrow corridor to another wall, where the roots of the tree formed an arch to accurately mark the location of the door.

"Can plants do that, especially when the magic of this world isn't that active. Hermione asked, looking at the arch made of tree roots in front of her, somewhat puzzled.

"Other plants in this world may not work, but we just saw that giant tree can. Ryan gently stroked the arch made of tree roots, and said, "This tree has absorbed a lot of special energy to grow to the point where it can break through the limits of the tree itself, don't forget that this place has a powerful energy source that can make great changes in this tree." ”

"There are other aspects to this change besides the size. Ryan summoned the Lady of Rose, who had summoned the illusion of the pendant, to open the door, and turned to the others, "For example, I just felt that the tree had now come to its senses. Although this mind is very vague, it is not even a complete soul. But I believe that in time this big tree will become a wise tree man. ”

"That's why after this tree communicated with you just now, its reaction has exceeded the limit of ordinary plants. Hermione nodded in understanding. Sometimes a powerful energy source does mutate ordinary creatures, at least they have seen more creatures in the radiation world that have mutated under the stimulation of a strong energy source.

As they spoke, the wall in the arch woven from the roots of the tree slowly parted to the sides, and a beam of light leaked out of it, illuminating the entire dark corridor.

After the stone door was fully opened, Ryan and the others realized that all the space inside the door had been completely occupied by plants. The roots of the tree enveloped the room, forming a cocoon of golden light in the room's array.

On the ground grows an herbaceous plant that can barely reach a person's height. These plants have straight roots and only a few egg-sized leaves in the top 1/3. They grew densely on the floor of this house, taking up all the ground.

"The Flying Stone Crystals should be in the cocoon around the roots of that tree. Ryan pointed to the spherical space in the middle. "I could feel the powerful energy coming out of it. ”

Needless to say, everyone present could feel the power inside that cocoon. Even people like Baru or Sidah who didn't know anything about magic felt that the light shining through the cracks in the roots of the trees made them feel lighter than before.

Ryan drew his wand and dotted it in the air at this time, and began to release a spell that was naturally friendly. Soon, a green ripple invited Ryan's wand head to fly out and sweep across the space.

Upon exposure to the green ripples, the herbaceous plants retreated as if they had been activated, taking away some of the silt from their roots. Soon, a stone path leading to the cocoon of light formed by the roots of the trees revealed in the grass.

As everyone walked down the stone path to the large cocoon formed by the roots of the tree, some of the roots parted to the sides, revealing a blue transparent octahedral crystal floating in mid-air. In everyone's sight, the crystal was constantly rotating in the air, releasing light and energy outward.

"What a powerful magic!" Ryan whispered in front of this crystal, in his magic perception, the crystal in front of him was like the sun releasing a large amount of magic to the outside world, but after leaving the flying stone crystal and walking next to it on a black stone platform engraved with cuneiform characters for a while, Ryan frowned.

"This is?" Hermione walked over to Ryan as his expression changed, then pulled out her wand and unleashed several scouting spells on the edge of the stone platform. As someone who has seen many top-notch alchemy techniques with Ryan, she quickly notices that something is wrong around her. "This method of using energy is too crude. ”

"What is the rough use of power?" asked Baru, who was confused by Ryan's communication. "What do you mean by that now?"

"Ah, by the way, I'll give you a protection first, although it is said that the magic energy radiation in this place will not cause any serious harm for a short time, but sometimes it is better to be cautious. After saying that, Ryan waved his hand and put a pink protective shield on the two children, and said to the two children who poked the protective shield with his hand curiously. "This is to protect you from the excess amount of magical energy you receive. ”

After taking care of the protection, Ryan explained, "To put it simply, this flying stone crystal in front of us is a great miracle, and it has a powerful energy inside to maintain the flight and the operation of the entire Sky City. However, the use of this energy by the ancient Laputans was too rough, and it can be said that this city in the sky is a typical example of the flying of powerful bricks. ”

"It's rough, but we feel like this city in the sky is already like a miracle. Sida subconsciously retorted that it was probably because as a descendant of the Laputa royal family, she subconsciously defended her ancestors.

"Didn't say your ancestors weren't great," Hermione reassured with a smile. "But the nature of this world makes it impossible for you to master magic as much as we do, and it is inevitable that you will have a rough and inadequate understanding of magic just through various props, in fact, your ancestors were able to do this very well. ”

"But if we use the technology we have mastered, the use of magic is far more perfect than it is now. I think it only takes 1/5 the size of the current crystals to keep this castle in the sky running. ”
