Daiki and Tatsumaki returned to the school using Daiki's Portal skill. When the two arrived back at school they had already forgotten why they were so worked up while Luna was peacefully sleeping on Daiki's bed back at their house while pretty much all of their parents and siblings were lying on a bed groaning in pain and exhaustion, the only ones exempted are Hina and Yuni.
Daiki's current goal is to be able to compress all of his chi into a ball which would undoubtedly be the size of at least planet Mars then if compressed more then the planet Mercury. The method of constantly compressing one's chi into a ball isn't all that new since once someone's limit was reached then they would need to compress it in order for them to gain more of it yet it is extremely dangerous as one wrong move and one's body would explode.
"Nakimura-san, what is your plot number?" Roy asked once he saw Daiki and Tatsumaki walking into the room.
"Hm? Plot 45, now that I thought of it, Tatsumaki what's your plot number?" Daiki asked.
"Plot 46, that is awfully close to your plot number" Tatsumaki was quite confused as to why her plot and Daiki's plot are close to each other.
"Didn't you guys know? students who have a significant other or at least their parents coming to a mutual agreement would get plots close to each other so they can have more opportunities to interact" Roy said while Daiki's lips spasmed, he didn't know about this, okay? this was the first time he heard of it since all of Vein's and Rain's friends are all single so they were always at the dorms of just either boys or girls.
"Okay then, I'm gonna build the mansion" Daiki said once they arrived at the plot then he casually tossed out mountains of materials out of his ODS to the point that Roy nearly fell over due to shock.
Seeing the enormous amount of materials and the familiar shapes of said materials nearly made Tatsumaki's eyes pop out of their sockets.
"Are you seriously planning on using those here? wouldn't that create a war?" Tatsumaki asked as she knew full well that even though Daiki didn't excell in anything academically he is weirdly enough much more efficient than the so called geniuses as his talent would always bloom yet he would not be able to name anything thus making him fail.
"Pretty much besides no one would dare to start a war once they see them, it's quite simple really, if the enemy has the guts to publicize this kind of mind breaking items then what else do they store that is being hidden" Daiki said while Tatsumaki shivered, fully remembering a past life where Daiki created a stalemate between the two warring groups when he showed up as well as the plenty of times he made a evil group that conquered the world start a civil war amongst themselves as he took the spoils of war.
2.10 million sq kilometers of space was provided for royal students and are engaged while the noble couples have 1.05 million sq km, 0.6 million sq km for normal couples and half of that for normal students who are single. Of course each of these are a separate floating island so Daiki can theoretically steal their's and make it his house in the future, just thinking of the possibility of him dropping down to the ground from the bottom or bottom side of his island like a maniac while his enemies' faces contort into terror is making him rejoice.
"Daiki please go easy here" Tatsumaki said hoping that Daiki would not do anything outrageous.
"Too late my main attribute is destruction and death while yours is creation and life so of course I would inevitably have made something that could easily kill someone" Daiki said then held the handle of Sapphire.
"Oh? is that so? then it's fine" Tatsumaki said as it felt reasonable for her if Daiki only managed to develop Sapphire so far however it still made her uncomfortable inside.
"Roy, do you want me to help with building your and Rina's love nest? just say it and I can make it to anything you want to be although I would need to trouble Tatsumaki to make a detailed sketch first" Daiki said with a smile, truly even if his core is destruction he still likes to create things which is quite the irony.
"How can I bother a royal of another race in order to just make a house?" Roy asked with seriousness since if that were to get out he would be criticized.
"Don't be reserved, we're all friends here!" Daiki said as he playfully hit Roy on the shoulder. Roy became speechless due to this but then remembered his troubles of making true friends in the past so he sighed and made a decision.
"Then I'll trouble you two" Roy said while Tatsumaki and Daiki smiled genuinely as Daiki prepared to make a gigantic mansion that wouldn't pale in comparison to the mansions in earth or any other mansions that he and Tatsumaki had seen in the past.
"Here" Tatsumaki said as she handed a piece of paper to Daiki while Roy became confused as he only saw a blank paper but then he saw Daiki smile as he put on a pair of glasses then he continued to click on something on it, once he finished he started working on the foundation which nearly hit the bottom of the floating island they were on.
Roy's lips couldn't help but twitch at Daiki easily making a giant hole then starting to harden the surface then covering it up with some strange substance.
"Take a look at this sketches first, if you have something you like then hand it to me and if you want to make changes just tell them" Tatsumaki said as she handed Roy stacks of papers as well as a special kind of glasses like the one Daiki wore earlier, Rina who was searching for Roy saw this and was jealous but then Tatsumaki sighed and made her wear the glasses then made her sit next to Roy.
The couple happily started looking at the blueprints while being stunned, Tatsumaki on the other hand wanted to help Daiki but was stopped by not only Daiki and Kōri but Kasai as well
"You know how you can't ever fix or make anything without awakening and even if you do they would be faulty so please don't!!" Daiki begged since for quite a lot of their previous lives cause of death was Tatsumaki's inventions.
After 10 full grueling hours for Daiki he had finally finished making the shell of the house as well as the landscaping of it's surroundings even a gigantic moon shaped pool came into existence while their whole mansion visibly resembles the sun once looked from above yet at the ground it still looks like a proper mansion but with weird sheds and warehouses around.
Seeing the entire shell of the mansion made Roy's and Rina's cheeks twitch, the two of them began doubting life but soon argued that those two weren't normal so they shouldn't compare themselves to them. Even if Tatsumaki only helped with the design and is currently decorating the interior while Daiki started to also install all of the necessary security devices.
"We won't be able to make your mansion today so how about the two of you stay with us for tonight?" Tatsumaki asked once she finished decorating one of the rooms, funnily the theme of their house is opposites that's why it looks weird and disproportionate yet it oddly looks great for anyone who sees it. Roy and Rina looked away hesitating.
"Relax you can just treat it as your home also, I mean isn't this beneficial for our kingdoms if their rulers are close?" Daiki said with a smile then he continued with setting up the alarms and of course the counter attacking traps, their house suddenly became stronger than most labyrinths.
"Then we won't be too polite" Roy said after having enough and just gave up on treating the two as royal friends but treat them as his siblings.
"Right! I have to do something down at the basement" Daiki said as he stepped on the center of a circle then tapped in a combination which made the ground start to sink.
Roy and Rina's mouth opened wide in awe as they saw it, Roy really wanted one as well while it would lead to a massive training ground and special rooms.
"Don't worry he will install what can be installed in your house as well and I am quite sure that an elevator is allowed" Tatsumaki said meanwhile Daiki finally arrived at the bottom. He pulled out Sapphire from his back then looked serious.
"[Dungeon Creation]" Daiki said as an invisible light blue wave with some dark spots covered the entire island.
"Dungeon Type: Monster House Labyrinth" Daiki continued whatever came to his mind then he poured out his chi into Sapphire making it glow as another wave of energy covered the whole place.
"Power Type: Sin" Daiki continued then a dark eerie wave spread across the island.
"Sin: " Daiki's words became incomprehensible when he said what sin would the dungeon derive from since a dungeon's qualities will be coming from which virtue or sin it's power is coming from.
