"Is there anything you need help with?"
Tatsuma saw through Sirzechs's thoughts, but he didn't pay too much attention.
Although not very obvious, a part of the reason why he was able to develop and grow so smoothly in the early stages was due to the Gremory clan and Sirzechs.
It's easier to talk when you have a backer. Without sufficient background, even a descendant of the Seventy-Two Pillars would be bullied.
Including this time with the Devil God Religion, Sirzechs has more or less provided him with a lot of help. Since that's the case, he wouldn't be stingy either.
Seeing this, Sirzechs breathed a sigh of relief and continued to explain the matter of the Seven Great Satans system.
"The Seven Great Satans system will to a certain extent divide the power of the Devil higher-ups. When I propose this matter, I estimate that a portion of the Pure-Blooded Devils will protest."
"Tatsuma, you might need to scare them a bit then... I mean the kind without resorting to violence."
"No problem, leave it to me." Tatsuma patted his chest, his expression confident.
It's hard to say about other races, but scaring Devils is a piece of cake.
Glancing at [God of Devils and Dragons (Black)], Tatsuma accepted Sirzechs's request.
"With me around, there won't be any accidents."
"Uh... then I'll leave it to you."
Sirzechs suddenly had an ominous premonition. But seeing Tatsuma's guarantee like that, he ultimately didn't say anything.
Not using violence, just releasing his aura to deter them.
Nothing should go wrong... right?
...
Gremory territory, western border.
Steel city walls stood on the border line, with giant fort placed on the walls.
A burly man got off the carriage and looked at the large-caliber fort on the city wall.
"Rias, did I remember incorrectly? Why do I remember this place didn't look like this before."
"Don't worry, Sairaorg. Your memory isn't wrong, everything you see now was built recently."
Rias also got off the carriage, greeting the soldiers lined up at the city gate to welcome them.
Amidst the shouts of "Welcome, Princess Rias", the two passed through the city gate and entered the interior.
The rural towns that used to be located in the fields were gone, replaced by towering buildings.
Devils drove giant machines, dragging various kinds of equipment on the concrete roads.
At the end of the line of sight, there were giant robots over ten meters tall constantly spraying concrete, expanding the city's edge.
Looking at these magical scenes, a hint of doubt flashed in Sairaorg's eyes.
"Rias, what exactly is going on?"
Rias said, "You should still remember the attack launched by the Khaos Brigade in various parts of the Underworld half a month ago, right?"
"Of course I remember."
"The area we are currently in is one of the areas in the Gremory clan's territory that was attacked." Rias explained.
Perhaps receiving intel, the people of the Khaos Brigade calculated the time and launched an attack when Tatsuma went to Soul Society.
In order to protect the territory, the soldiers of the Gremory clan immediately formed a defense line and counterattacked.
On the battlefield at that time, there were quite a few enemies with the strength of Mid-Class Devils and High-Class Devils.
With full firepower, the border of the Gremory territory was heavily damaged. Those very backward small mountain villages located in the border area were basically affected and destroyed.
This kind of situation is rare, but not unprecedented.
In the past, there have been cases of high-level monsters and stray Devils breaking into the border and causing destruction. Often at such times, the Gremory clan would send aid personnel to help these border Devils rebuild their villages.
However, just as the Gremory clan was discussing who to send to the west as aid personnel, Yahweh stepped forward.
On the way to the Underworld more than a month ago, Yahweh obtained a territory from Rias, which was exactly the western border of the Gremory clan.
Including the territories of Tatsuma and others, a large area of the western border is managed by Yahweh.
After negotiation, Yahweh took over the management rights of the western border from Rias's parents, further expanding the territory she controlled.
After that, she came to the border, took out various high-tech tools, and personally led the border Devils to rebuild their homeland.
"Sairaorg, what you see now is Yahweh's achievement in the past half month."
"Can such a level be achieved in just half a month? It's truly astonishing." Sairaorg let out a sigh of emotion.
As a traditional Devil, he had always been insensitive to things like technology. This was the first time he had witnessed firsthand what high technology could achieve.
"Let's go, I'll take you to see Yahweh."
Rias took him to the tall tower in the center of the city.
Taking the teleportation array to the top floor, a blonde girl wearing a white coat appeared before them.
"Good afternoon, Rias."
"Good afternoon, Yahweh."
Rias replied, then turned to look at Sairaorg standing behind her.
"Yahweh, this is my cousin, the new successor of the Bael clan, Sairaorg Bael."
"The successor of the Bael clan?"
Yahweh carefully sized up Sairaorg, a look of contemplation in her eyes.
"No Power of Destruction, but the physical strength and battle aura quality are very high."
"It seems you've put in a lot of effort to become the successor of the Bael clan."
"However, the people of the Bael clan are all old fogeys, your situation must be very difficult."
"It is still within manageable limits." Sairaorg's expression became serious.
To see through his background and infer his situation in such a short time. This level of insight was somewhat terrifying.
"Come with me."
Yahweh led Rias and Sairaorg to the reception room, and a robot followed them in, placing tea and desserts on the table.
"It's my favorite time again."
Rias reached out and picked up a piece of dessert. "Sairaorg, you should try some too. These are very delicious."
"Then I won't be shy."
Sairaorg also picked up a piece of dessert. The next second, an indescribable deliciousness bloomed in his mouth, and a faint warm current flowed down into his abdomen. Vaguely, a comfortable feeling came from his body, and the fatigue accumulated from his daily life was swept away.
"Hmm?"
Noticing the change in his body, Sairaorg looked at the remaining desserts on the table with some surprise.
"Yahweh-san, these..."
"It's not anything precious."
As if she had guessed what Sairaorg wanted to ask, Yahweh's voice sounded first.
Picking up the teacup and leisurely taking a sip of black tea, Yahweh leaned back on the sofa, her expression lazy. "There are many gluttonous little ones at home. This is a dessert I specially researched for their physical health after meals."
"They are all made from readily available ingredients, I won't charge you, feel free to eat."
"Yahweh-san, I appreciate your kindness, but before enjoying the dessert, I have something I'd like to consult you about."
Sairaorg unconsciously clenched his fists, a flicker of inconspicuous anticipation and nervousness in his eyes.
"Have you heard of the Sleep Disease?"
"I've heard of it."
Yahweh thought back for a moment.
Regarding the Sleep Disease, she had heard people mention it during the time she served as the God of the Bible. It was a disease that spread among Devils, causing the afflicted to fall into a deep sleep and their bodies to constantly weaken.
Because they had the support of powerful bloodlines, Devils focused more on developing their strength. In terms of medical technology, they had almost no points invested.
There was no research at all on the Sleep Disease, a disease that only a few Devils contracted and was not contagious.
Therefore, even after she and the Satans perished together, no one had researched a method to cure the Sleep Disease.
