Reincarnated as the Demon King's Son

"We can help the war, but first we have to finish the dungeon," Aldred said.

"Let's go to the dungeon immediately," Bartrem said.

Aldred nodded and summoned Teethless and his air-cavalry unit comprised of 55 Bajaragon.

One was large enough for all of them to ride on, but Aldred wanted to travel with style this time.

They hopped on to the Bajaragon of their choice and immediately soared into the sky.

The people in the city gaped when they saw dozens of large, red dragons flying into the sky. Some guards were even panicking and thought they were under attack, but after they saw the dragons headed towards east, they calmed down.

"Are they going to the Lair of Treasures? Should we tell someone about this?"

"You fool. That's the Death Lord."

The platinum Ranks that guarded the cities only glanced at the sky a bit before they returned to what they were doing.

As Aldred arrived above the ruined city, he saw the adventurers were in the midst of battle again.

"Do they fight everyday?" Aldred asked.

"It's because you killed Bruce," Rachel said. "The Epolissa adventurers want revenge."

"I see. Bruce. Take care of them."

Bruce appeared on Teethless and before bowing at him and jumping down towards the ruined city. Immediately he shot down all the opposition one by one.

Aldred on the other hand immediately told Teethless to enter the dungeon entrance. He nose dived to the ground, and then swiftly flew inside the small entrance of the dungeon by retracting its wing. Using inertia, Teethless entered the deep part of the dungeon before he could finally release his wings.

All 55 Bajaragon followed suit which shocked the adventures nearby.

Aldred did not care about that and immediately called all of his undead that had been ravaging the dungeon. All the treasures had entered his divine dimension, but he wanted to enter the 10th floor quickly.

"We should call Xer Xai," Aldred said.

"But it will destroy the dungeon, and the monsters in the 10th floor might come to the 1st floor," Rachel said.

"I did not consider that."

Throwing the plan away, aldred bull dozed through the dungeons with his undead army.

Meanwhile, Aldred kept on creating golems after golems using the stones around, and he threw some treasures in them.

What he created was the fighter unit. Since Bartrem said that this unit was the most reliable, he wanted to create a hundred or so to help him in the war later.

The Bajaragons belched flame within the tunnel, burning all the monsters.

The undead army marched forward in an orderly manner and the weaker monsters scurried away in fear.

He had created a bunch of fighter golems and he let them help the undead in defeating the monsters. Some boss-type monsters appeared in the tunnel, but his army overwhelmed them quickly.

A day passed in the dungeon, and Aldred already created 100 units of fighter golems.

Next, he created the gunner golems. It wasn't as complicated to make as the artillery golems and it was fairly powerful.

As they continued deeper into the dungeon, Aldred kept on forming mana crystals and inserting them onto the golems so they could use the Fire Bullet spell.

"Aldred, what about the magical construction spell? Are you not going to experiment with that?" Rachel asked.

"Of course, I will. But I have to do it one at a time. You know what, I am going to do it now. Who knows it might help me win the war quicker."

Aldred already had an idea of what to create, he just had to realize it. First, he built a small pillar and put dozens of mana crystals inside of it.

He spent a few days constructing the spell and with the help of Magical Construction spells, he successfully created something unexpected.

A pillar was thrown in the midst of monsters. It stabbed the ground and suddenly shot out a powerful energy in all directions, bringing all the monsters down to their knees as their weight increased by a significant margin.

"Gravity spell?" Sophia asked.

"It's not really a gravity spell, but it has the same effect."

The golems gunned the monsters down with their fire bullets, and they kept going forward.

With undead and golems working together seamlessly, they quickly reached the entrance of the 10th floor.

In front of them was a thick gate with unimaginable height.

Aldred commanded his army to attack the gate.

The Bajaragons and the gunner golems sent flames at the gate.

The flames roared and lit up the entire cave while sending a wave of hot air. The gate was sturdy and powerful, and it took them hours to melt a hole in it.

Aldred entered the hole, and what greeted them was a wonderful yet weird sight. Glowing vines dangled from above, and there were all kinds of crystals below with some shining plants on the wall.

The cave was like a circular hall. It was wide and tall, enough for all of his army to move around and there was still a lot of space.

From above, his army looked so small compared to the amount of empty space the cave had.

Aldred looked above, and saw a gigantic semi-transparent, soft-gold egg that gave off a wonderful glow.

"What is that?"

Suddenly, the cave trembled and some rocks fell and shattered to pieces.

Aldred looked to the side, and saw something.

He narrowed his eyes, and then his heart skipped a beat. "Get out of here! Something is coming!"

Before they could scatter a gigantic creature crashed near them, sending them rolling on the ground.

The monster snorted out hot steam, and it roared as it slammed the ground with its gorilla-like arms.

"Shit!"

The creature spun, whipping its spiky tail at them.

"Duck!"

They all ducked down and the tail missed their heads.

The undead swarmed the monster, but it easily threw them away. Its size made all of his undead look like ants.

Aldred gritted its teeth. "Fuck! It's a Platinum Rank monster!"
