Rias, as a spectator, existed as an insignificant presence throughout the entire process.
But even so, it made her deeply realize the importance of power.
Rosen didn't idly after dealing with Li Zevim.
He directly dispersed the Dragon Eater Samael, who was sealed deep in Hell, and took away the cold device.
Hades wanted to stop him, but his power was insufficient. He could only watch helplessly as his greatest trump card was snatched away by the God of the Bible.
No, that's not right.
Dragon Eater Samael was originally created by the God of the Bible.
However, the treasure valued by Hades was not so important in Rod's eyes.
After all, as the name suggests, the Dragon Eater is extremely effective against Dragon-attributed beings, but when used against other enemies, it can only be considered something carrying ordinary venom.
Even if hit, it won't kill, at most causing minor injuries.
But if a Dragon-attributed being is hit, a weaker one might die on the spot.
Issei Hyodo, the male protagonist in the original work, died directly after being poisoned by Samael. If the Infinite Dragon God Ophis hadn't shared her power later, allowing the male protagonist to reshape his body, the original male protagonist would no longer exist.
After leaving Hell, Rosen first sent Rias back, and then, based on the memories he extracted from Li Zevim, he found the place where he kept the Beast of Revelation, successfully retrieved it, reinforced the Seal, and then continued to Seal it in "World's End."
[Fallen Angel: "Phew~~~, it's finally over. I didn't expect things to be quite troublesome."]
[Spirit of Time: "It's over, but what's with your sigh of relief? What does this have to do with you?"]
[Fallen Angel: "Of course it does!"]
[Spirit of Time: "Like what?"]
[Fallen Angel: "Isn't it tiring for me to cheer for the big boss?"]
[Spirit of Time: "Alright, you win~.."]
[Hells Fubuki: "I didn't feel much when I saw Rosen deal with Li Zevim, but when I saw that Beast of Revelation, I felt that this monster was truly outrageous. In my world, it would be considered a Divine Rank disaster."]
[Avenger: "If we judge by the destructive power of the Beast of Revelation, it's highly likely. After all, this doomsday behemoth can be considered the top combat power in DXD, right? Besides the God of the Bible and the Infinite Dragon God, no one can restrain it."]
[I Dont Want to Eat Monsters: "Eh? Isn't there also Great Red?"]
[Spirit of Time: "That doesn't count. As long as it doesn't go to the Dimensional Gap, even if the Beast of Revelation destroys the entire Earth, it won't intervene."]
[Fallen Angel: "Don't forget the Evil God from the adjacent EXE. Those three guys are truly terrifying. Even someone as strong as Great Red is just a roadside existence."]
[Hells Fubuki: "The problem is solved, but it seems not completely solved."]
[Red-haired Demon Princess: "If you didn't mention it, I would have forgotten about it."]
Rias was naturally very happy that Rosen could come and help resolve the hidden danger.
But as soon as she entered the chat, she saw the group members talking about the adjacent EXE World, and her mood immediately soured.
After all, she had just solved a big problem, and now she had to figure out how to deal with an even bigger problem. Isn't this just messing with people's minds?
However, Rias couldn't do anything about it, as the objective facts were there.
If Great Red hadn't been so diligent for so many years, perhaps the robots from the adjacent world would have already invaded.
[Shepherd: "Regarding EXE, there's no need to worry too much. As long as Great Red is still there, nothing will basically go wrong."]
In fact, there were several reasons why the Mechanical Evil God from the adjacent world in the original novel invaded this world.
The most important one was Great Red, who was originally just a background character, but was summoned to the Human Realm from the Dimensional Rift time and time again.
Coupled with the protagonist group's power inflation in the Late Stage, the aftermath of various battles could even interfere with the Dimensional Rift. No matter how powerful Great Red was, it was only one, and it couldn't maintain the entire Dimensional Rift.
But even so, Great Red persevered until the protagonist group finished fighting the Beast of Revelation, and it was only after several more years that the robots from the adjacent world took advantage of the vulnerability.
However, the ending wasn't very good.
Great Red was casually cut down by the Hegemonic Evil God Regal Zeva as if it were a roadside existence, and the protagonist group fought against the robots invading Earth in the future.
Of course, Rosen didn't know what happened next, as the original author left it unfinished when he Transmigrated, and the future plot was only covered in a separate volume.
Of course, Rosen wasn't worried.
Since EXE currently poses no threat, there's no need to care too much.
[Shepherd: "According to the plot, even if the EXE World develops smoothly, it will take several years. Even if it doesn't accelerate, it will take a year, and this year is enough for all of you to become stronger."]
[Red-haired Demon Princess: "That's the only way."]
After Rosen said that, Rias immediately felt much more at ease.
[Fallen Angel: "Oh, by the way, since that world is safe now, can we go there for a group activity? I'm very curious about the Heaven Realm there!"]
[Magic Old Man: "As soon as it's safe, you plan to go. Typical you."]
[Fallen Angel: "How can you say that?! I don't like it, take it back!"]
[Fallen Angel: "Besides, wouldn't I just be causing trouble by going there? It's fine to deal with some small fries, but as soon as the boss goes, it's directly a high-end match. Even if I go, I can only stand by and cheer."]
[Fallen Angel: "You've said so much, just tell me if you're going or not?"]
[Magic Old Man: "(Zhao De Zhao) Yes, I'm quite curious about the magic there."]
Frieren only learned that magic was an exclusive ability of demons when she watched the anime.
If humans wanted to use magic, they needed to sign a contract with a demon.
Therefore, Frieren wanted to specifically research the differences between demon magic and the common magic she had learned.
[I Dont Want to Eat Monsters: "I... I want to go too."]
Marushiru's reason was as idle as Frieren's.
[Avenger: "I'll go too. I have to deal with those children all day here, so I'll occasionally take a break."]
In the end, basically all the group members wanted to come and see the world, except for the workaholic Makima and Empress Esdeath who didn't have time.
[Fallen Angel: "It seems like one person is missing."]
[Fallen Angel: "Moon Goddess, are you coming?"]
