On the other side, where the portal opened, it was a wasteland.
There were only dead trees, dead plants, and similar things. Not even an insect was living here. Tens of thousands of devil soldiers were swarming the area like swarms of ants and started guarding the area. After soldiers came through the gate, thousands of Arcane Mechanical Automatons swarmed through the portal and started digging into the ground.
"What are your spiders doing Zeo?"
Asked me Venelana as we walked through the portal.
"They are building a fortress around the portal. Then they would move onto the Penta-Runic Magic Tower Formation, which would be built inside the fortress, and the Octa-Runic Magic Tower Formation, which would be built around the entire area where the fortress would be located. We need this place to be protected best to our capabilities, in case this fortress is attacked."
I answered her back.
Now the most important thing was to build fortifications around the portal and defensive formations, in case of attack. If this portal is destroyed, we are all f.u.c.k.e.d up very well, as to build a new one, we would need to search the whole plane for suitable resources. If an enemy has the power to destroy the portal, he would be far stronger than my army. So in short, portal destroyed = f.u.c.k.e.d up.
"General Borke goes and secure perimeter of twenty kilometers, kill everything, and if possible capture some intelligent lifeforms in the plane."
I gave an order, as General Borke bowed slightly.
"General Amyke, organize soldiers to help Arcane Mechanical Automatons in building the fortifications, we need them to be built as soon as possible."
He also bowed and left to help to build fortifications.
"Lord Pheles, if you mind, together with your apprentices, scan the area and start laying protective spell formations. Then join General Amyke and Arcane Mechanical Automatons to help to build the fortifications."
I gave one order after another after just Venelana stayed with me.
We have sat together, as I conjured two chairs and a tea table and started brewing tea. As proper Lord, and Commander of this expedition, I enjoyed the view while waiting for tea.
"So, how long do you think this conquest will take?"
Asked me Venelana as we were sitting down and observed everything below us. As the soldiers and Arcane Mechanical Automatons were working hard to build fortifications and everything around it.
"Depends on strength of natives. Preferably less than one year. If the natives here are stronger than initial thought, then it would take even more. From what your grandfather told, the peak of this plane should be only Ultimate-Class, something we can deal with."
I explained while finishing the brewing process of tea.
"And what if they are above?"
Asked me Venelana curiously. If there was something on Satan-Class then we are in deep problems.
"Then I will call help. Though I believe it won't be necessary."
I said slowly, to which Venelana nodded.
We continued drinking tea until soon enough was dark and each of us went to sleep in our tents that were constructed.
A day after, I was in a meeting with Lord Pheles, General Amyke, and General Borke Zagan. Even Venelana was here though she looked pretty bored as we were discussing military things.
"The fortress around the portal together with Penta-Runic Magic Tower Formation would be constructed within one week maximally, afterwards we could start the march."
Said General Amyke his report.
"Lord Pheles, when can you cast a large-scale magical scan?"
I ask while looking at Lord Mephisto Pheles.
"Preparations are done, now just we need to wait until the Penta-Runic Magic Tower Formation and Octa-Runic Magic Tower Formation. Then we would be able to scan the entire plane, as this world is not that big. Probably only 50% of Draconic Deus, not counting all planes connected and tied to the Draconic Deus."
This was probably the best course of things to scan the entire plane in one go. Casting large-scale scanning scan was troublesome, casting such spells, would require probably experienced Apocalypse-Class to scan the entire plane.
For Mephisto to cast such a spell even with help of Penta-Runic Magic Tower Formation and Octa-Runic Magic Tower Formation was a good feat. Also, it will save a lot of time. With one spell, we would have a detailed map of this entire plane, with all notable locations, and even settlements. Or at least, what is on the surface.
In regard to an underground world, if this plane has something like that, we would need to do it by ourselves.
"Very well, then we will wait for one week until Penta-Runic Magic Tower Formation and Octa-Runic Magic Tower Formation are constructed and then we will start. Generals, how are my Legions?"
I asked as I looked at General Amyke and General Borke Zagan.
"Half of them is working together with Arcane Mechanical Automatons on the building process, while half guards the area. They change their roles each day."
Replied General Amyke.
"Morale is high, and soldiers are eager to fight."
Replied General Borke Zagan.
"Have we encountered some monsters or other species?"
I ask.
"Not many, only a few hundreds of monsters, strongest being only at the Commander Level monster. They were soon turned into rations... besides that nothing."
Stated General Borke Zagan.
"Good, but be on guard if General Level monster shows up. Start searching through this entire area we have termed as wasteland and kill everything. After Penta-Runic Magic Tower Formation and Octa-Runic Magic Tower Formation is completed and we have a complete scan of the Yestera Plane we will start the march."
I gave out my orders as both General Borke and General Amyke bowed slightly and left the tent.
"Lord Mephisto you and I will go and help to construct magical defenses over the place."
He just nodded before my eyes looked at Venelana.
"Venelana, you will protect the home fort."
I said to her. General Amyke was tasked with protecting the outer perimeter, General Borke was in charge of the search, while I and Mephisto were doing magical defense. So Venelana as the last Ultimate-Class was tasked with the defense of the portal.
