Finally at home...

Draconic Deus, Underworld, Territory of the Gremory Family, Castle Fuerig

As I breathed the air in the Underworld, a fascinating, unnaturally satisfying feeling went through my entire body. After six months or so, I was finally back home. I even felt a bit stronger when I returned back.

Really, devils were stronger in the Underworlds.

Now that I was back home, I had some time before departing for the Asgard and Nine Realms. At first, I needed to hear a report about the development of my territory during the half a year I was gone, but probably not much has changed. As on long-lived race, devils accepted changes very slowly.

After several hours, I finished meeting with Castellan of Castle Fuerig after learning nothing much had changed. Venelana went to enjoy luxuries of the Underworld that weren't available during the planar conquest, while I sent a message to old Zekram that the conquest was successfully made.

Just as I sent a message to Zekram, I thought about Crom Cruach and the contract I had with him. Maybe I should send him to the Yestera to kill those Monarch Level sea monsters, as he would be most suitable for the job.

What was surprising was that after twenty minutes, I informed Zekram that I had already sensed his energy signature in my castle, as he was already here, waiting for me in the castle's lobby.

"Lord Zekram."

I greeted him when I entered the lobby.

"Lord Gremory Lucifer."

Said he with a slight smile.

"I see that you were eager to hear about my success. Though I must say, there were small complications; I think I should get an excellent mark for your test."

I said with a slight grin.

"Indeed you have. I didn't expect you to finish it so soon; probably, those magical technology things are powerful. So, how are the results? Is it enough to affect the incoming war?"

Asked Zekram with a serious voice.

"Yes. Just half of the resources from the Yestera Plane, which is located on the continental part, are enough to construct several Mechanical Legions, Artillery Battalions, and even Voidfleets. If we gain complete access to the bottom of the sea, then our gains would be much higher. Alas, the sea is ruled by seven Monarch Level sea monsters, and my current abilities in this matter are minimal."

I answered truthfully, to which Zekram nodded in satisfaction. Apparently, he was astonished at my quick and splendid success.

"In this regard, I can help you a bit and kill some of them. From Venelana's letter, I know that you, Arcanotech, would be a great boon to the devil race. Additionally, I want to personally see Mechanical Legion in combat before deploying them on the battlefield."

Said Zekram, to my shock.

"I would be grateful for your help. We could depart after I finish my tasks to the Asgard and Takagahamara and, of course, reach Satan-Class... with my current progress, it won't take much time. Till then, we will leave it be."

I answered as I led old man Zekram to my garden, as I wanted to drink some tea. We soon arrived at the garden and sat down.

"Currently, the state of the Yestera is peaceful, as all sentient life on three continents was annihilated to the last one. Sea is still full of monsters, but they are now lying low after their defeat on the mainland when Merfolk tried to attack the northern shores of the mainland. I have left half of the expeditionary army together with Mechanical Legions under the supervision of General Amyke, as there are still many things to do there. Within one or two months, I expect that all the entire three continents of the Yestera Plane would be completely industrialized, from mining to manufacturing."

I said to him about the current state of the Yestera Plane.

"That is good. I need you to manufacture defensive arcanotech structures and weapons, especially artillery, to fortify our position further within the next year. Most fortresses and fortified positions depend on some magical technology bought from Aesir, but they are selling us only basic things or old ones. Your Arcanotech is more advanced, and most importantly, it is available for us."

Stated Zekram.

If all strategic points, such as military Fortresses and some strategically located Castles, could be armed with Anti-Matter Magicule Canon Batteries and Arcanotech Towers, it would drastically increase their offensive and defensive capabilities. They would be much harder to breach and could cause tremendous damage to the enemy during siege or battle.

"It shall be done. I will accept payment in raw materials such as ores, metals, and magic crystals in addition to classical payment in Soul Coins. Within two months, the factories would start production first products that could be sold immediately. Operating most of the Arcanotech weaponry is very easy and accessible through the terminal installed in each weapon."

I informed Zekram when I expected things to work to their fullest.

"Excellent. I would like to order 10 Mechanical Legions, million Drones, 1,000 Anti-Matter Magicule Canon Batteries, and 25 Lunar-Class Cruiser Voidships if that is possible."

And then he dropped a bomb. The sheer size was enormous. Fortunately, with my current production abilities, producing such a size was indeed possible with enough time.

"You need to pay half of it in raw materials. Currently, mining and processing work in the Yestera are just in the infant stage, and the supply of materials obtained from that world is still rather low. To produce an army of such size would take a long time without sufficient materials; if you give at least half as payment, then it could be finished within four months."

For Zekram to have him on my good side, I will give him a discount so he would have it cheaper. If he supplies the raw materials at least for half an army, then he would get it for free as I won't charge anything for the manufacturing process.
