While Others Cultivate, I LVL UP In My Sleep Using The Dungeon System

Bursting towards the falling Giant Goblin King in the air, Adam could feel the wind crashing against his face and was flying through the air at rapid speeds as he released continuous bursts from his palms and feet.

Adam closed his eyes that were struggling to see with the wind that was crashing against his face and it was usually easy for his eyes to handle on land, but now there weren't any trees, buildings or objects to block some of the wind.

Despite having his eyes closed, Adam could navigate and sense his surroundings with his spiritual sense and once he slowed down would open his eyes.

The Giant Goblin King was calm and wouldn't be hurt much by falling onto the castle.

Adam reached behind the back of the falling Giant Goblin King and launched an Air Palm Strike at its back, but it didn't even nudge the Giant Goblin King in the slightest as Adam moved out of the way of the beast.

He would be crushed if the beast fell on him and it would be a waste of energy and effort if he tried to stop it, so he just gave up and let the Giant Goblin King fall onto the castle.

However to Adam's surprise, as the Giant Goblin king landed on the castle, the castle didn't break and collapse under him.

It stood there unaffected by the Giant Goblin King falling onto it and the structural integrity of the castle wasn't damaged in the slightest, which amazed Adam, but also worried him slightly.

"No wonder the explosion that the Mage Goblin King caused in its tower didn't affect the tower. I thought it was merely because it didn't aim to break the castle and only its tower, but I guess I was wrong and the castle is probably indestructible" realised Adam.

If even the Giant Goblin King falling onto it wasn't able to break through its walls, then even if Adam used his Killing Move, he would struggle to break through which meant that he would only be able to enter the castle through the main, front entrance.

It also meant that if Adam got trapped inside, he would struggle massively be able to break out and there were too many things that he didn't know or understand.

The castle seemed to be made out of the same rock as the towers and the rocks used were identical in colour and texture, and yet the tower was a normal building that could be broken through and the castle seemed indestructible.

There were too many possibilities for the reason why the castle didn't break after the Giant Goblin King fell on it.

It could be that the castle was somehow being enhanced or that it was made out of a different more powerful material than the tower or that the system's program was protecting it from being destroyed.

Either way, Adam was relieved that the mysterious, massive castle wasn't destroyed, as he still wanted to explore it and search for any valuables, but it also changed things as if he was stuck inside, what would happen next.

There were so many things running through Adam's mind, but they all disappeared when a giant fist was launched towards Adam.

While Adam was surprised and thinking about the reason behind the castle's durability and what he could expect inside, the Giant Goblin King had gotten

It was surprisingly fast despite the size of the Giant Goblin King and its fist was the size of a house, which made it even harder to dodge.

Adam sensed the attack and burst to the side while staying in the air, then burst himself onto the hand of the Giant Goblin King.

Running along the arm of the Giant Goblin King, Adam used his Step Skip Skill and then when he neared the body of the Giant Goblin King, jumped off its green arm.

Just as he jumped off, he narrowly dodged the other hand of the Giant Goblin King that had slapped down on where Adam was previously running with great force.

Falling close to the Giant Goblin King's body, its giant abdominal muscles were amazing to look at and each one of the Giant Beast's abs was dozens of times larger than Adam's entire body.

Despite that, there was a deep wound in the centre of its stomach that Adam had previously deal it while it was still enlarging and that was the tactic that Adam had used against most of the other Giant Goblin Beasts that he had come across.

The Giant Goblin King was much larger, stronger and faster than the other Giant Goblin Beasts that he had faced, but other than that it didn't seem to have anything special about it.

If it hit Adam once, it might not even need a second strike to finish off Adam, but hitting Adam would be very difficult, especially with his Burst Movement Skill.

Adam also wouldn't sit idly while the Giant Goblin King tried to hit him as he flung two energy blades at the Giant Goblin King's open wound, using the Dual Slash Skill.

The Giant Goblin King's muscles and giant body was very durable and hard to pierce through, but since Adam had wounded it before, he could continue to strike that same point and take down the beast.

Their battle was a long one with the vitality, durability and stamina of the Giant Goblin King, but after continuously striking the open wound of the Giant Goblin King, while dodging all of its attacks and being careful, Adam was finally able to take it down.

In the process of their battle, Adam had tried his best to lead it into the Inner Part of the Goblin Beast City and cause as much damage and destruction outside of the Core Part of the Goblin Beast City as he could.

With three of the Goblin Kings already down, all that was left was the Weapon Master Goblin King that would be found in the Final Tower.
