He quickly finished the letter, handing it to Kane. Kane had done this many times, so he didn't need any explanations at all.
The next morning Kane waited at the post office with Void Step active. The system that the two of them come up with involved putting the envelope meant for Guildmaster Bradt at the of the letter stack of the postman's carriage.
This way they didn't need to register. Rui was not foolish enough to send letters following the systematic protocols in place. That would give him away pretty easily. Guildmaster Bradt merely needed to identify the individual who posted a letter on the same day that he got a letter from the Voider, and he would have a small and manageable list of suspects for the Voider's identity.
Once he saw Kane or Rui on the list, it would mostly be game over since the two of them would probably be the only Martial Squires on the list.
This way, there was simply no trace of the letter entering the system. Given that Guildmaster Bradt had no idea at what point the letter entered the system, it instantly became too impractical to pursue the avenue as a way to figure out who the Voider was.
Rui simply needed to wait. He had already told Guildmaster Bradt to send him the information through their regular method.
"He's probably already deposited the information," Rui remarked, turning towards Kane. "Drop me to the Shionel Dungeon."
"What for?" Kane frowned.
"I purchased information from Guildmaster Bradt," Rui explained. "On Chairman Deacon."
"Is this related to your plan of getting somebody else to do all the hard work on the fourteenth floor?"
"Yep," Rui nodded. "I'll tell you about it once I get all of the information."
"Alright, let's go."
Kane and Rui quickly headed towards the Shionel Dungeon completely undetected under the influence of Kane's Void Step. They quickly headed to the first floor.
"Sense it yet?" Kane asked, turning to Rui.
"Yep," Rui nodded. He could clearly sense a box of documents buried at a remote edge of the first floor.
This was the method that Rui had given to Guildmaster Bradt to communicate with him. Every time Rui entered the dungeon with Kane with Void Step, he scanned the first floor at least once for any potential message from Guildmaster Bradt.
Although this method was somewhat pointlessly elaborate, tedious, and crude, it gave Rui the home-court advantage. He simply did not trust himself to not be tricked by Guildmaster Bradt if they were to exchange transactions through normal means. Rui was incredibly intelligent and shrewd, but it wasn't as though Guildmaster Bradt was a fool, worlds away from it. Rui did not think it was wise to tangle him in an arena that the old man had a lifetime of experience in winning in.
That was why Rui chose a method of transaction where he had a dominant upper hand. The fact that he was undetectable in the Shionel Dungeon, and could sense everything when no one else could, was an advantage that he didn't think Guildmaster Bradt could beat.
"Here it is," Rui told Kane.
"Alright, let's dig it up," Kane cracked his knuckles.
"Wait," Rui told him. "I have some preparations to make."
"For digging something up?" Kane frowned. "Do you need a shovel?"
"No, I need this," Rui pulled a full-body suit from his dimensional storage before donning it from head to toe.
"What on Earth is that for?" Kane frowned.
"It's because I don't trust Guildmaster Bradt," Rui remarked. "You should get away from here."
Kane had no idea why Rui was being so paranoid, but he shook his head, following his instructions. Rui quickly dug up the box, pulling it out, and opening it up.
"Hm?" His eyes widened as he the second he opened the box as he detected something strange.
His normal senses only saw a bunch of documents, but his Riemannian Echo detected a gas with a far lower density being released from the box, curving space less, thus allowing him to sense it when he shouldn't have been able to. If not for his Riemannian Echo, he probably would not have even realized something was wrong.
('This is either a kind of sleeping gas that would have knocked me out had I inhaled it,') Rui realized. ('Or it would have served some way for him to locate me outside of the Shionel Dungeon.')
He suspected it was probably something like the latter. Guildmaster Bradt had probably thought there was a good chance that Rui would have fallen for it without realizing it, allowing him to finally figure out Rui's true identity.
"Fucking bastard," Rui cursed, yet he smirked. The full-body suit he had on ensured that he was not touched by it, and he had sent Kane away, so he successfully foiled the trap.
He put the box into his dimensional storage, before moving a hundred meters away from the area, and then putting his suit back into the dimensional storage.
"Are you done?" Kane sighed. "Let's go already.
"No, wait," Rui shook his head. "I was right, Guildmaster Bradt did try pulling some trick, even though I'm not sure what the trick was."
"What?" Kane's eyes widened. "What do we do?"
"I've got it covered," Rui put his thumbs up. "We cannot take the box outside of the Shionel Dungeon."
"Why not?" Kane frowned.
"There's a good chance that we'll be caught if we do," Rui simply replied as his mind sharply analyzed his circumstances and came up with several solutions, before quickly identifying the best one. "Here's what we're going to do. I'll read all the documents here in the Shionel Dungeon, and memorize all the data from start to. Then I'll thoroughly destroy the box and the documents, and then we'll leave after that."
This way, if the box had some way to be tracked, then it wouldn't matter, since it could not be tracked in the Shionel Dungeon due to the jamming trait of the Shionel Dungeon.
