One week later

After one week, I arrived with my Legions in the wastelands of the Yestera Plane; the entire place had changed tremendously.

The first thing to notice was probably the entire place had been turned into one massive military outpost. Around the portal, the majestic gothic-looking fortress was built by Arcane Mechanical Automatons and my soldiers' combined effort while incorporating their Penta-Runic Magic Tower Formation created from Five Magic Towers, which were part of the fortress.

Several miles away, one could see eight Magic Tower that was creating the Octa-Runic Magic Tower Formation. Below these wonderful structures, thousands upon thousands of soldiers were swarming as they patrolled the area or trained.

"So, how are the results of the magic scan Lord Pheles?"

I asked Lord Mephisto Pheles as we were in the war room that was located on the top of the fortress.

"Of course, Lord Lucifer."

He said lightly, calling me only by the name Lucifer. He then conjured a map of the entire Yestera Plane.

"This entire plane has landmass around 50% of Earth Plane. It has one continent and two sub-continents, which are not too far from the main continent. This continent we are located in, we have named Ewor. Another sub-continent we named Ihor, and the main continent is addressed just as Main Continent. Now to the Ewor Sub Continent."

Explained Mephisto Pheles as he conjured the image of the Ewor Sub Continent.

"Now, we are located at the southern edge of the subcontinent. Only a few miles south of our position is the sea. Our only way to expand is to conquer the entire southern area, which is inhabited by three human barbarian tribes, and several small monster nests or human settlements."

Pointed Lord Mephisto Pheles to the most southern point of the image.

"What about the three tribes?"

Asked General Borke Zagan.

"Not too much of a problem. They are very weak, with only two Ultimate-Class barbarians among them. While they may have Ultimate-Class physique, with Tier Magic, killing them should not be a problem as I already tested the magic resistance of these barbarians, and it is weaker than expected. Other Magic Systems, as Aesir, should do the same work. Population wise, they have around one million population altogether, while combat wise, approximately half of them is able to fight, but they are weak."

Explained Lord Mephisto.

"General Amyke, General Borke, Venelana, each of you will take three Legions and twenty Anti-Matter Magicule Canon Batteries and annihilate all those tribes. Leave none alive; use corpses to lure monsters there so that we can annihilate them in one scoop later."

I commanded in a firm voice.

During the last few days, final adjustments to the Anti-Matter Magicule Canon Batteries were finished, and I already ordered manufacturing them. As the portal was constantly being opened, I could have a stable flow of crucial resources or reinforcements from home.

If you spot this tale on Amazon, know that it has been stolen. Report the violation.

Yesterday, Anti-Matter Magicule Canon Batteries arrived.

They looked like I remember them with their futuristic design. Forty of them were immediately mounted on the Fortress Gremory, which was actually the official name of the fortress.

Leaving me with sixty Anti-Matter Magicule Canon Batteries that could be used in the field. Each of them had firepower comparable to Tactical-Tier Spell, meaning destruction from Town to City Level.

In this conquest, it is annihilation. I don't need survivors, especially no some human barbarians or goblinoids. I need an entire plane to be empty, as I planned to mine even core. Mining the plane's core wasn't something heard of in the Draconic Deus as it would lead to the plane's destruction.

Still, in my previous life, the Solar Federation was mining cores of Stars or Planets rather often as they were massive sources of energy that could be used in creating special weaponry or devices.

The entire southern area was controlled by these human tribes, who were barely able to survive raids of the goblinoid tribes from the north, but thanks to the territory advantage, especially the valley that was the only available route from north to south, human barbarians were able barely to survive their aggressive and brutal attacks.

Soon after, Generals Amyke and Borke Zagan bowed and left the war room to go and organize legions, while Venelana still remained there.

"I know, Vena, that to you, it may sound to slaughter everyone from infants to old people, but alas, this is how wider works. Those with bigger fist rules, and now were are ones with the bigger fist... and to keep this advantage, we need to do everything in our power. Even if it means committing atrocities on weaker and innocent."

I said to her in a cold voice.

I personally didn't care even if billions or trillions of innocents die; for me, they were just numbers; I would gladly kill even for the life of a single devil. This was probably when I finally realized that even with my memories, I was now devil through and through.

In my past, during the Stellar Exodus, similar scenarios were common. Races were being slaughtered and annihilated by Solar Federation for the greater good of humanity if they were deemed a threat after the militarization of the Federation.

I went to Venelana and kissed her gently on her forehead.

"You don't need to have mercy with anything that isn't our ally. Remember that, well, they are either with us or against us, nothing else and nothing more. Those who stand with us or serve us shall be rewarded; those who stand neutral need to make a choice where to stand, and those who stand against us shall be annihilated to the last person."

I said gently as she nodded her head and departed as well, while Mephisto Pheles gave me a weird look.

"You have more in yourself from Satan Lucifer and first Gremory than you can imagine."

Said he silently before he left the room.

"Possibly yes... probably."
