"So... is this building now being used for... experiments?" Shi Wanyun pointed to the wall behind her that had just closed and asked.
Number 5 nodded: "Yes, itâs for experiments, but the details of the experiments cannot be disclosed to you for the time being."
"...Those are of the same species as the âownerâ here, right?" Shi Wanyun ignored the lack of disclosure and asked again.
Number 5 smiled and shook her head: "Of course not. Do you think I have the right to experiment on a higher intelligence than humans?"
In that sense, indeed...
"Then they are..."
"If you want to know, complete this mission first." Number 5 didnât reveal more information but started operating the console, the keys clicking rapidly under her hands.
Soon, there was a light sound from the other side of the room, and a hidden door slowly opened.
Shi Wanyunâs attention was drawn to it.
A hidden door?
Wasnât there no door on that wall just now?
She looked inside the door.
Beyond the door was a space as large as a factory floor.
She exclaimed softly and walked over, finally seeing what was inside.
"That is..." she said in surprise.
"A teleportation device," Number 5 explained, "You can use it now."
"Teleportation... device?" Shi Wanyun examined the large apparatus closely, "Is it something similar to a Transmission Array?"
Inside the door, at the center of the factory-like space, stood a gigantic metallic pillar adorned with intricate patterns, made of segments of varying thickness. The thickest part was about two meters in diameter, and the thinnest about one and a half meters.
Just from the exterior, the metallic pillar exuded a strong sense of technology.
At first glance, she thought it might be some high-tech weapon from a giant humanoid machine.
"Yes. Youâve probably seen the Teleportation Array Pattern at the Transmission Array, right?" Number 5 asked from behind her.
"I have; the prerequisite for activating the Transmission Array is to activate the Teleportation Array Pattern."
"The teleportation device..." Number 5 explained the usage and function of the device to her.
"... Can be buried in the ground?" Shi Wanyun asked, "It doesnât need to be powered?"
"As long as itâs near the treehouse, it can function with the treehouse."
"I see, the transport coordinates..."
Shi Wanyun wanted to take a closer look at the high-tech metal pillar and just as she was about to step through the door, Number 5 held her back.
"I have something to give you, donât go in yet."
At the same time, Number 5 handed her a ring.
"This is..."
"If I tell you itâs a Space Ring, would you understand?" Number 5 returned to her seat.
"...I didnât expect to actually get something youâd only see in novels..." Shi Wanyun marveled at the ring in her hand.
"This is something Iâve developed. Itâs only available here," Number 5 smiled.
Shi Wanyun lifted the ring and examined it closely: "You made this? The material of the ring..."
The material of the ring seemed like stone, yet like metal, presenting a deep gray color, a material she had never encountered before.
[Space Ring (Blue): A ring with a small space for storage, usable only for storing specific items.]
Only for storing specific items?
"Youâve actually invented a Space Ring." Shi Wanyun looked up at her.
"Iâm not that great," Number 5 waved her hand, "Itâs just that others are uninclined to make this sort of thing."
"Uninclined? Why?" Shi Wanyun was puzzled.
A Space Ring like this is surely better than a backpack.
"Because the tools with spatial storage functions are made of this special material, and the more materials used, the storage space increases exponentially. A small piece can expand a cubic meter, two pieces ten cubic meters,"
Number 5 explained: "Given this, spatial storage tools are at least made large as bracelets to have practical use. A ring is too small, using too little material, so the expandable space is very, very small."
"Then this ring..."
Shi Wanyun lightly turned the ring.
She couldnât control the ring to retrieve anything from it.
"Put it on first."
Shi Wanyun complied and put the ring on her finger, then gently turned it.
Her eyes immediately widened, quickly looking toward the open door, then back at the ring on her finger.
"Thatâs right, inside it is the teleportation device," Number 5 looked at the ring on Shi Wanyunâs hand, "The Owner instructed me to give it to you, to set it beside your own treehouse. It seems you will have some missions requiring travel in the future."
"I see... But the internal space of this ring isnât small."
The teleportation device wasnât small; even a big truck might not fit it.
"Thatâs because Iâve altered how space is utilized with my research and modifications. To expand the space, this ring was specialized to only store one item. The teleportation deviceâs size is already the limit the ring can hold; its practical value isnât that high."
Number 5 chuckled with self-mockery: "But thereâs no choice; I have limited materials, and even this kind of ring canât be made more than ten times. If made normally, the total material used for making spatial storage tools wouldnât even be enough for a box-sized space."
"Then you must be quite capable," Shi Wanyun said softly, somewhat unwilling to part with it, "At least, you canât feel the weight of any internal item with this ring."
Even a violet-level backpack has a weight of 5%; without this ring, she couldnât possibly bring such a large metal pillar back.
"Space storage tools, of course, have no weightâafter all, they open up a space directly. Your backpacks are different and canât really be considered space storage tools, more like space compression tools."
"I see..." Shi Wanyun turned the ring, her mind stirred.
This thing might be of use in the future too.
"Alright, Iâve said enough, take this,"
Shi Wanyun took the card Number 5 handed her, on which was drawn a...
Teleportation Array Pattern?
"In the future, if you want to teleport, you can always..." Number 5 explained the method of teleportation to her.
Shi Wanyunâs heart stirred with slight waves.
She could actually freely travel between her treehouse and the World Tree!
"When you return, youâll appear in this room," Number 5 pointed to the room where the teleportation device was, "This room is sealed, but donât worry; once the device is activated, Iâll notice and bring you out."
Which means that upon her return, Number 5 will be aware, and sheâll need Number 5âs permission to be let out from here.
Itâs not a problem, but it does make her feel...
"Is there only this one teleportation device inside the World Tree?" Shi Wanyun asked tentatively.
"Thereâs one more, but you canât use that one,"
Number 5 shook her head: "That one is in the most populated area under the World Tree, and anyone teleporting there would be noticed by everyone. That teleportation device is usually used to transport new members annually, and your mission is confidential and cannot be known by others."
Her mission... is confidential?
Only when Number 5 mentioned it did she realize.
Why was there such a laboratory and a deeply hidden transport device in Number 5âs residential area?
To maintain secrecy?
What is being hidden from whom?
Hiding it from the people below seems pointless, doesnât it?
All this, wasnât it the monster instructing Number 5 to do these things?
Could it be that the "Owner," that monster, is hiding something from other monsters...?
Forget it; itâs not something she needs to delve into.
Whatever the monster wants to do isnât something she can think about now.
"Alright, thatâs all I wanted to tell you. Now, you should head out; the crystal ball containing information will inform you of other matters."
Shi Wanyun nodded gently, hesitated no more, and stepped into the room where the teleportation device was located.
The door closed behind her as she stepped inside.
Immediately, the patterns on the teleportation device before her shone with a purple-black light!
Then her vision was swallowed in an instant, and when she opened her eyes again, she was already under her own treehouse.
Before she could celebrate, the crystal ball in her hand suddenly lit up.
Then she felt her body starting to weaken.
...?
Whatâs happening?
