"Do you want me to help with the heaven's research on the Interdimensional Room?"
Riser looked at Irina strangely.
"I-I am sorry! Bu-But heaven is stumped, Riser-sama... and... and this room is important for us..."
Unlike before, it was hard for Irina to be so ignorant in front of Riser, but this was normal since their status was much different. However, there was no doubt that her request was too much.
Riser was the leader of the devil and even the alliance, but he was asked to become a researcher for the Interdimensional Room, which was a job that should be taken by a researcher instead of a leader like him.
Naturally, he was familiar with this room, as it was a room crafted by the angel to fight their extinction.
Due to the death of the god, it was impossible for the angel to reproduce anymore, and unlike the devil and the fallen angel, who could mate easily, the angels couldn't do that as they would fall due to lust.
Some angels might be able to remain sane and hold their beliefs, but with the many numbers of fallen angels in this world, it was clear how limited the number of angels that could hold their beliefs before they fell.
There was no doubt that it was trouble, but similar to the devils, they tried to create the reincarnated angel by using an item similar to the "Evil Piece," but in their terms, it was known as a "Brave Saint."
In front of him, Irina also happened to be one of the reincarnated angels.
Nevertheless, even if they had created a reincarnated angel, they weren't satisfied as the reincarnated angels weren't pure-blood angels. They also wanted to have their own pure-blood descendant, like the devil.
So, this Interdimensional Room was their solution.
However, the angels always had one weakness, and that was the fact that they didn't have a good researcher. Unlike the fallen angel and the devil, the angel didn't have a desire; thus, they didn't have a will to improve. It was also due to this reason that there wasn't anyone exceptional in business and research on the angel side.
This was probably also the reason why the angel side let the humans take care of most of the matters in the church, as they were also helpless in this situation.
It was the same case as the "Brave Saint," as it was developed by Ajuka previously.
This Interdimensional Room was a project under Azazel, but Azazel had died. Even Ajuka, who was in charge of the technology in the Underworld, also died.
If there was something fortunate, there were many fallen angels and devils who could handle these technology matters. Riser also sometimes came to help, taking care of those complicated things, but as he was lazy, he only came to help when he remembered. Still, it was also due to this that whether the devil or the fallen angel only focused their research on what was important for their races.
This Interdimensional Room was one of those useless, complicated inventions, but it was meaningless for the devil and the fallen angel, so along with the death of Azazel, the angels didn't know what to do since their knowledge of this research wasn't as good as Azazel's.
Michael had always wished to visit Riser, hoping he would take care of this, the International Room for the future of the angel, yet with Riser's position and his position on the alliance, he knew that doing so was as good as mocking Riser.
While Michael was clueless about what to do, Irina came and told him that she was willing to help, which made him feel conflicted, but in the end, he agreed.
"I beg you, Riser-sama. Please help us to complete this Interdimensional Room."
Irina begged so hard that she even groveled on the ground.
"...."
Riser was speechless before he let out a sigh, picking up Irina on the ground. "You don't need to grovel like this. If Xenovia saw us, she would think that you had a special hobby."
"I-I don't have a special hobby!" Irina refuted with a blush as she let herself be picked up by Riser.
Still, it might be their first time being so close to each other, especially when he was holding her armpits to lift her up.
Irina felt so strange somehow; her body became a little hot, and she felt a little naughty for some reason. Still, she knew that she needed to complete this mission as it was important for the angel, but when she tried to think about what to do, Riser said, "Well, I will help you."
"Huh? Really?"
"Yes." Riser nodded. "Where is the room?"
"Here, Riser-sama." Irina quickly took the door handle out of her bag and gave it to Riser.
Riser looked at the door handle of his hand for a while before he stuck it on the wall of his villa. It was connected automatically, and when it was opened, it was connected to a simple room. Still, the room had a fancy bedroom and was decorated with angel statues, portraits of various Saints, and other religious items, which made him a little speechless somehow.
Still, if it was before, he would feel uncomfortable, but now?
He was okay and didn't feel much different than walking on the street.
Still, as he entered, Irina also entered and closed the door, but when she turned, she saw that Riser was looking at her. "What's wrong, Riser-sama?"
"Nothing."
Riser wondered whether Irina didn't know anything and just pretended that she didn't notice anything, but he felt that it should be the former since this girl was still a virgin.
"So, can you fix this, Riser-sama?"
"Who do you think you are talking to?
If it was someone else, it might be hard for them to solve the problem in this room, but for him?
It was so easy, especially when he got the "Dimensional Lost" and the "Innovate Clear." Still, even if he didn't have those two, he would still be able to solve this problem. Checking it for a while, he quickly solved this room and made it a truly safe place for the angels to have intercourse. As long as they had sex in this room, he knew that they wouldn't fall.
"It's finished."
"Huh? Really?" Irina was surprised.
"What? Are you doubting me?"
"No, it's just... the angels work so hard, yet they are unable to do anything, so... I am just surprised." Irina laughed awkwardly.
"Then, do you want to test it?"
"Test?"
"Yes, to see whether this room is working or not since it is for the future of the angel, right?"
"That's true, but what should we—" Her voice grew quiet, and she realized what they should do to test whether this room would work or not. Her face grew a cute blush as she stared at him with moist eyes. Her heart was beating so fast as she thought about what Xenovia often told her.
Irina knew that this was wrong, yet somehow, she also anticipated it.
"Wh-What should I do, Riser-sama?"
"Just leave everything to me."
Hearing his words, Irina nodded shyly as she let him teach him the forbidden knowledge that had many angels to fall from their grace.
