The Demon Lord's Rebirth

Chapter 3: Building his forces

Jin stood up and dusted off his clothes.
"Phew, it's been a while since I had to erect a castle to live in. Even so, the first stage is complete. Now, to fortify it," Jin thought to himself aloud as he prepared. Then, with a snap of his fingers, golden magic circles began surrounding the sides of the castle, threatening to swallow it whole. However, this wasn't the case as once the magic circles had gotten close enough to the outer walls, they began rotating slowly, and each process began drawing in magic power from Jin's seemingly limitless pool of mana. Once the mana capacity of the magic circles was complete, they faded into the castle walls without a trace.

"That should just about do it for fortification magic. It's not as though the castle won't be guarded in other ways as well. Now to test it out," Jin said to himself as he picked up a small boulder and flung it at the castle.
As if the castle was alive and aware of an incoming attack, the magic circles reappeared and began shooting out countless golden lightning arrows, all directed at the boulder. In less than a second, the boulder was reduced to smoke and rubble, and the magic circles faded back into the castle's outer walls.
"Just as I had expected," Jin said with a smile on his face, pleased with the results.
"Now, for stage two."
He slaps his hands together and then slowly pulls them apart, concentrating very hard so that his powers don't go haywire. As he focuses on drawing in energy while removing his hands from one another, a large, shining red scythe could be seen being formed from within his hands. As the scythe becomes clearly visible, he grabs the scythe and spins it above his head and then back around until it is in front of him.
The aura emanating from this red scythe is astounding; it could even be sensed from hundreds of miles away. "Now, the preparations are complete. With this much power in the scythe of life, it may be able to summon some interesting creatures to serve me. Well, let's find out!" Jin says, clearly enjoying this.

"Death commands all and all commands death. Come forth and awaken yourselves to the living!" He shouts as he slams the blade of the scythe into the ground. Once the scythe was plunged into the dirt, it began making cracks around it. Then, those cracks became fissures until they became so deep underground that even Jin could barely see. What rose from the ground was a giant five-mile-wide staircase built from what looked like cobblestone, yet it seemed far more durable than something as simple as stone. Jin stands there, waiting for something to happen, and his waiting did not disappoint him.

In a matter of minutes, he could begin seeing fire rising from the ground and from above, like the sun. One staircase going up, the other going down. Alongside the fire was a strong gust of wind that was threatening to enrage the flames even further. There were screams of people being burned alive, and yet there were no human bodies. It was the very definition of 'Hell's Fury,' as giant ten-meter-tall fire golems began walking from beneath the ground and up the stairs toward the plains. It wasn't just two or three golems, but over ten thousand! All seemingly made of stone and magma that had become fused, with flames raging on their outer bodies that threaten to burn anyone who gets near them to ash.
As the sun turned blackish red, what seemingly shot out of the ground and rose to the skies above, were three-meter-tall evil archangels with black wings and shiny white armor, holding swords and lances alike.
"Ha...hahaha! This is getting more enjoyable by the second!" Jin bursts into a burst of maniacal laughter as he begins clapping his hands in a show of appreciation for what has been summoned.
"With this, stage two is nearly complete. We still need to get you guys some generals to lead you all, now don't we?"
