As expected, Aze-san's business was about the banquet invitation from Burainan Clan.
Since Aze-san couldn't leave Boruenan, I went with my companions and attendants.
"Hohou, gravity magic huh--interesting."
"Yes, it was something used by a greater demon."
I give the introductory book of gravity magic to the high elf-san of Burainan Clan.
Only 10 basic spells are written in it.
Magic that can be used once I can chant them are not limited to human magic. I'm now also able to use dragon language magic to create dragon spring liquor and demon magic.
Gravity magic was a magic used by the blue-skinned Nari demon that appeared in the opening performance of the [Golden Wild Boar King] fight in the Duchy Capital's underground.
I had trouble analyzing it since there were only two spells which I copied by ears.
After understanding the way to interfere, create and annihilate graviton, everything after that are all my original magic.
I might even be able to create a small black hole if I gathered all the magic power on the planet.
"You're only teaching Keze of Burainan, it's unfair!"
The one who forced her way between me and the high elf of Burainan Clan was the high elf of Beriunan Clan.
Both of the clans like to research, but unlike Burainan Clan who are like investigators, Beriunan Clan regards Burainan Clan as a rival.
"Saze of Beriunan huh. Can't you at least greet when you're visiting other clan."
"Oh spare me, we've known each other for 100 million years. We're like family right."
Miss Saze slides onto my lap like an eel.
Tama and Mia who were absorbed in the banquet looked at Miss Saze with "Oh no!" expressions, but it seemed they lost to the dishes' charm and went back to eat them.
"This is a thanks for letting me inspect the library of Burainan Clan freely."
"What! Then you can also look at Beriunan's library all you want, so give me magic book too."
"That's fine by me."
I took out a gravity magic book from my satchel and gave it to Miss Saze.
I'm not hiding the introductory books anyway, and I've also given it to Aze-san and Boruenan Library.
"Hee, so this is also preserved food... There's no taste?"
"That is because these Chlorella pills are specialized for mass production and long-term preservation."
The reason why it's lacking taste unlike the ration in the snow kingdom is to prevent it from destroying the market of the existing preserved food. Rations created with Lulu's involvement are too delicious.
I've developed this to help places where disaster or famine occur.
Lulu and Chlorella rations are being endlessly produced by the dolls in the satellite factory in the void sky.
The most troublesome process, freeze-drying, can be done there with low cost.
The factory can create 100.000 of the former food in a day, and 10 times of that for the latter as long as the ingredients are available.
Moreover, since the latter's ingredients only consist of Giant Kelp and Deep Shellfish that clings to the kelps, there's no fear of them running out for the time being.
The Giant Kelps that extend from the trench to the surface are ridiculously big.
"Might as well make sweet preserved food."
"Mold grow easily on sweets you know."
"Then you can just seal it."
"The canned peach pickles with syrup are delicious aren't they."
The high elves of two clans are talking about the preserved food in excitement.
Looks like I've successfully planted interest about preserved food to the two.
"Right, I've got my hands on this thing--"
I ask them to analyze the pitch black [Philosopher's Stone] crystal that I got from the black octopus.
"What is this?"
"It looks like a kind of Sacred Tree Stone."
The two high elves look at the crystal's light with interest.
I think the only difference is in its color, but I sure want to know if there's any meaning behind that.
