After killing the Cadre-Class Ten Winged Angel, I went to the location where Grayfia was dealing with the weaker ones that were just on the Ultimate-Class or High-Class.
Grayfia was much stronger than all Angels, so she killed them all with rather ease, and with one of the most basic spells of the Tier Magic System, called Counter Spell, she could easily defend against Light and Holy attributed attacks from them.
On the other side, most human exorcists were just Middle-Class, and only one or two were High-Class, so they weren't any kind of threat. Humans in Draconic Deus were just at the bottom of the ladder... probably from the intervention of Pahtneons since ancient times.
It seemed logical.
In Astral Boundary, humans were among the strongest species, with Arcanists and Warlocks leading and having countless powerhouses. Probably before or shortly after the Dimensional Gap was created, the Gods of Draconic Deus severed paths for humans to get stronger and made them depend on faith.
Not something rare across countless planes of Astral Boundary. Those planes ruled by Gods usually have other species living there on a tight leash. Often crippling their lineages, it would be impossible for them to practice any Power System or entirely depend on Gods. It would be dangerous for them if their subjects could get stronger without dependence on faith... often, it would lead to violent retaliation.
Across Draconic Deus existed many books and information about Astral Boundary, especially in older factions. There were even inheritance sites in Dimensional Gap of mighty begins of other races that fell here.
"Grayfia, what have you found there?"
I asked as I looked around, searching for something of value that they were so vehemently protecting.
"It's there..."
Pointed Grayfia at a huge chest that was inscribed with countless protective runes. As I looked at them closely, they were Divine Runes crafted by a god, and these looked like runes crafted by Yahweh himself.
I opened the chest and almost froze in shock.
Hundreds of Divine Crystals were there, and the most shocking thing was that they were all of High-Grade. Intermediate Divinity Stage Gods used divine Crystals in the High-Grade to strengthen their powers and Divinity.
These were priceless. With such an amount, one could practically create twenty to thirty Intermediate Gods from nothing. This, of course, led me to a question, what Heaven wanted to do with such a huge amount of Divine Crystals.
Only Pantheon currently that had the ability to produce such an amount was, of course, only Heaven. The fact there were present on Cadre-Class Ten Winged Angel and several Ultimate-Class Eight Winged Angels wasn't a good sign.
"Grayfia searches the room for clues... maybe we could find what they were trying to do with such amount of High-Grade Divine Crystals."
Grayfia then went to search for clues as I did the same thing. I did the same thing, and we started searching underground rooms that were hidden under the Church. After several minutes, I found some Divine Grimoires on the Divine Magic of Gods, and soon enough, I had my answer.
They were trying to create the artificial Divine Kingdom that Yahweh had designed here in Japan. Every God had their Divine Kingdom, Gods would often create their Divine Kingdoms outside the plane they Ascended, or they would infuse their Divine Kingdoms into Pantheon Dimensional World to make it stronger.
Usually, Gods were stronger in their Divine Kingdoms. Angels here in Japan were trying to create the artificial Divine Kingdom that would give them a stable foot in Japan that would allow them to create a practically turtle shell fortress.
While the artificial Divine Kingdom would be weaker than the genuine one, with Yahweh's number of followers, he had more Divine Crystals than other Mighty Gods of the same rank. He used most of them to strengthen Heaven to create an extremely strong Divine Kingdom and only a few on himself.
He could easily strengthen this artificial Divine Kingdom to rival the genius one.
If Angels had one here, they could easily recover their strength, as Angels would regenerate many times faster in an environment filled with Holy Power. They could also connect this place directly to Heaven and start a bigger invasion if needed. They were pretty unlucky; they didn't manage to construct it before I came.
If they did, then I couldn't destroy it. Only combined forces of many gods of Takagahamara and at least three Greater Gods would stand a solid chance to destroy something like that. The reason for that would be the strong Divine Kingdom, and on top of that, Yahweh would send at least two Archangels to protect that place.
With the amount of Divine Crystals I had, I could give some of them to Hela, it would easily allow her to reach the peak of Intermediate Divinity Stage God, and she would have a good chance to enter Greater God Stage.
Or she could create her Divine Kingdom, as she still didn't create one. Maybe I can convince her to fuse her Divine Kingdom to the Underworld, though that would be risky, as they are several other gods inhabiting Underworld, and such action could cause war.
Especially with Hades, his Divine Kingdom was infused to the Underworld, and it was no secret that he despised devils. While he wasn't exactly the strongest Greater God in the Draconic Deus, he was a pain in the ass to deal with due to his Divinity.
I used a spell to store the chest with Divine Crystals. I would think about their usage later... they could also be used as money as such things as Divine Crystals used as currency across the Astral Boundary.
"Come, we need to get out... I want to have this entire mess already behind me."
I said to Grayfia.
As we exited, she cast a most destructive spell to set everything in here on flames, so even ruins would be turned to ash.
After that, we went to Kyoto and to the final destination of Takamagahara.
