The two followed her back to the rest room, where the table was covered with discarded blueprints.
“This is it!” Valerie pulled one of the sheets of paper from a pile of drafts.
At first glance, it can only be described as "chaotic," and even after looking at it a few more times, it is still incredibly chaotic.
I'm afraid that no one but herself can understand it.
"What the hell?" Xiao He asked directly.
Valerie did not explain immediately. First, she drew a rectangular array on the left wall of the room, and then went to the right wall of the room and drew a seemingly identical pattern.
The two onlookers watched in astonishment as she entered from the right and then exited from the left.
But as soon as she stood still, the pattern on the right wall disappeared, leaving only the "door" on the left.
“That’s what ‘only one person can pass through’ means.” Valerie scratched her head helplessly.
Xiao He and Wang Xuefeng exchanged a glance and simultaneously thought of a certain item.
A teleportation scroll?!
Valerie was taken aback by what they were saying.
Xiao He walked a few steps to the table, took a whole roll of draft paper from the table, cut it to a length of about 1.67 meters, and then fixed it to the wall with tape.
"Come on, draw it again."
"All right."
Valerie didn't suspect anything and started drawing with the special array pen.
"I've finished drawing it! It still connects to the door on the left."
Xiao He nodded silently, stepped forward, tore open the tape, took the finished "scroll" in his hand, and slowly rolled it up.
Valerie watched her movements closely from the side.
At first, I didn't understand why she rolled it up, but later I realized that she was just testing whether the formation would fail after it was rolled up.
“Huh? I hadn’t thought of that yet…” Valerie said, tilting her head.
"Take a look, is there a problem with this?" Xiao He handed the rolled-up formation back to her.
"Let me take a look..." Valerie took it, first feeling it from the outside, then opening it to check it again.
Finally, she said with absolute certainty, "No problem!"
"Then I'll try to go through. Remember to open the door," Xiao He reminded him.
“Okay!” Valerie nodded emphatically.
Holding the painting in one hand, Xiao He casually walked to a corner of the room.
Valerie blinked, and then tossed the scroll above her head, causing the more than one-meter-long scroll to unravel.
Then, the petite figure slipped into the air and disappeared along with the pattern.
Turning my head, I saw the array on the left wall shining brightly.
Xiao He's figure appeared inside the wall, like a reflection in a magic mirror.
Valerie traced a circle on the wall with her finger.
Like unlocking a lock, as the "gears" turned, the various lines and shapes within the formation began to change.
"Snap!"
All the lines automatically separated, leaving a maximized ellipse in the center, accompanied by the power of a spatial vortex.
The next moment, Xiao He took a step forward.
"Whoosh—" Valerie rushed over and hugged her waist.
Because this was the first person besides herself who unconditionally trusted her and was even willing to test her with his own body.
Valerie was moved to tears upon seeing the results of the experiment.
"This thing works really well!" Xiao He was also very excited, giving it a thumbs up repeatedly.
Wang Xuefeng silently looked at the "paintbrush" in Valerie's hand.
He noticed that the brush would lose some "ink" every time it drew a formation, so it must be a consumable item for formations.
The Nuojin Academy is rich in resources, and SSS-level array masters have extensive resource purchasing authority, not to mention the monthly subsidies they receive.
Xiao He also noticed this issue of consumption, so he asked, "What are these pens made of?"
“Concentrated energy.” Valerie thought for a moment. “Any type of energy will do, even concentrated elemental power, but the best is still space concentrate.”
"What is that? How do we get it?" Xiao He asked again.
“This kind of stuff usually appears very deep underground and takes decades to settle. Moreover, it is mined by specialized engineering teams because special containers are needed; otherwise, even if you see it, it would be very difficult to collect it,” Valerie explained.
"I see..." Xiao He frowned slightly.
"What's wrong? You want one of these pens too? Or do you want to make one yourself to play with?" Valerie blinked curiously.
Xiao He shook his head.
Her idea was to provide Valerie with energy in exchange for some "teleportation scrolls" for a rainy day.
Because she never directly asks people for things.
If she really wants something, she will try to exchange it for something of at least equal value.
Even if all else fails, money will do.
Of course, she's still happy to put in the effort if there's a way to save money.
Wang Xuefeng understood her thoughts and silently took out a "battery" made by Yang Xing. This was the power source for the mechanical wing, and he had quite a few more in his backpack.
"Here, this is for you. Could you please draw two teleportation scrolls for us?" Wang Xuefeng handed the battery to Valerie.
The latter's eyes lit up immediately, and he examined the strange battery from all angles: "What kind of amazing thing is this?! Did you buy it from the advanced energy market?!"
"More or less." Wang Xuefeng didn't reveal any information about Yang Xing.
"This, such a big piece, and... you gave it to me?" Valerie looked at him in disbelief.
"Hmm." Wang Xuefeng nodded slightly.
"Waaah... Waaah!" Valerie suddenly felt a lump in her throat.
"As many of these formations as you need in the future, I'll draw them for you!"
Because this is an extremely expensive energy source, which she cannot afford at present, every stroke of her pen causes her unbearable heartache.
Although she didn't quite understand social etiquette, she decisively interpreted Wang Xuefeng's gift as "support for her experiment," which led to her emotional words above.
Wang Xuefeng couldn't help but chuckle, but shook his head.
"You don't need too many. We're not just teleporting each other around for fun. Draw two copies for us, and you can keep the rest for yourself."
“No!” Valerie’s tone left no room for argument: “I will send you any new inventions as soon as possible!”
Seeing her insistence, Wang Xuefeng didn't explain further: "Then thank you in advance."
"You're welcome! I should be thanking you!" Valerie gave a proper military salute.
"Keep it up, you're amazing." Wang Xuefeng smiled slightly.
"Thank you for the encouragement!" Valerie said, bursting into tears.
Under her passionate calligraphy, Xiao He and Wang Xuefeng each received two scrolls.
Since it's only the first version and can only transmit in one direction, once, and to one person, they don't need to stockpile too many.
Compared to the "swapping" of the rings, one-way teleportation is naturally safer.
Encouraged by both moral support and financial incentives, Valerie was in high spirits. After seeing the two off, she plunged back into her research...
