As I flew through the countryside I saw a lot of titans milling about on their business ignoring me, but one or two looked up as if to see confirm what was that noise I was making. Those are probably the irregular types and likely those who ate enough people to start regain their human consciousness if my theory is correct. It's been a while since I last read the manga.
When I reached civilization I started blaring a song from my memory that was thankfully converted into the appropriate files. I didn't had Ride of the Valkyries in it's entirety, but I had something that sounded relatively appropriate as an epic music.
[X]
I passed through several villages and made sure to fly by above a couple of the districts to make a scene, until I reached the palace of the city where the queen resided. I cut off the music before blaring my loud speakers in order to draw her out.
"QUEEN HISTORIA! I AM COMMANDER RYUAN AND I HAVE A PROPOSAL TO MAKE TO YOU AND YOUR SUBJECTS. BRING IN THOSE YOU TRUST TO HEAR MY WORDS, AND BRING TO ME ONE EREN YEAGER TO LISTEN TO WHAT I HAVE TO SAY. TELL HIM I WILL BE THE INSTRUMENT WHICH HE CAN HAVE HIS DREAMS COME TRUE. GO OUT OF THE CITY AND HEAD EAST WHERE MY FORCES ARE WAITING FOR YOUR ARRIVAL. I ADVICE AGAINST MISSING THIS MEETING."
I cut the loud speakers and headed east where my air construction facilities would create a temporary base to host my guests, optimized for normal humans to utilize it's facilities. Now I just had to wait until they arrived.
~~O~~
While my avatar waited my Commander body was busy expanding into the visible region, killing all titans I came across. I had to stop at some point, around a thousand units, because I simply couldn't micromanage everything anymore. I started to put my Kbots, vehicles and aircraft into patrol mode on a wide area and forgot about them before focusing on another region.
I also took the opportunity to send a construction vehicle to make a shipyard for me to make sure that there were no surprises on the ocean. By now my economy had reached ludicrous level and it was a matter of time before I could completely saturated the planet with my forces. With the AIs set to fight against the titans it was a matter of time until I cleared the whole territory of the former Germany. Frankly the harder part will be finding the titans after a certain point, and only the fact that I still didn't had much experience with multitasking even after the sim time prevented me to go full Planetary Annihilation on their asses.
Still I managed to find a couple of human communities hidden across the countryside and I was ready to make contact and make them an offer they can't refuse. Now it was a bet to see which side I would encounter I will approach first, the walled city or the communities.
~~O~~
In the end it took a few hours for Historia to come out, while bringing in a veritable army of course. I also saw Eren and Mikasa approaching from another side, but that was expected as she sent a horse earlier and must told him the situation in order to meet with her. Also the base that wasn't there a couple of days ago sure helped to distinguish where he should meet her.
I waited them come with a couple of Kbots at my side, and when they arrived they were surprised and fearful of what they saw.
"Welcome, welcome", I said while slowly walking to their direction, "welcome to my temporary base. My name is Ryuan, a pleasure meeting with you."
I heard a couple of mutters about how this base wasn't there yesterday and I chuckled. "While it's rude to build a base on foreign soil without the owner permission I didn't wanted to look like a poor host and meet with you all on tents. Rest assured after our business is concluded I can dismiss those buildings if you feel uncomfortable." It would be easy to reclaim the buildings if I wish so, after all.
"What are you?" Asked a man and I just stared back at him, pondering what to tell him. In the end I decided on the most simple, most infuriating and slightly heretic response.
"I am what I am." I gave him making him become almost invisibly annoyed, which I picked thanks to my superior senses and processing power. "Looks like Eren arrived", I said to no one in particular as my Kbot in that section of the base went to greet the teen. "Anyway, please come in. Everything will be answered shortly inside."
Sir what's-his-name came from the side of Historia (and wasn't that a funny image seeing her trying to convince the other people to allow her to come? In the end she had to pull rank), stepping up with false bravado. "I don't think the queen will go anywhere until we get some answers first."
I could see a few people fighting the urge to face palm, while others of lower rank didn't had that reservation.
"Sound fair I suppose. I believe I shall start with the most obvious questions first." I snapped my fingers for effect, and a squadron of bombers flew above us and at a certain safe distance they dropped their bombs on some random empty space nearby, shaking the ground and scaring the horses. I let them calm down their animals and themselves before I continued. "This was the least I could do with just what I have on hand, you can send someone to confirm the devastation I caused in less than five seconds. If I wanted to force the issue I certainly could, but I came here to negotiate, not to conquer. Anything else you want to know before we start the meeting?"
They were all pale as they looked at the still smoking ground on the distance, before one of them sent a scout to see what I did. I let him and we waited.
And waited.
And waited.
A long time later he came back very pale, as if he had gone a round with the colossal titan barehanded. "I think... we should listen to him", he said a bit hysterical, "It couldn't hurt?"
The rest of the delegation looked at each other, before grimly following me.
Ah, diplomacy. Have a soft word and carry a big stick, and few beings have bigger sticks than a CORE Commander.
