Souta's group along with Aerin was standing on top of the cliff. They were staring at the seemingly endless trees below them.
"The castle lies in that area," Aerin said as she pointed at a certain area within the forest.
Princess Dreimi was confused as she couldn't see any castle.
Eilish glanced at her and explained, "There is a barrier that hides the appearance of the castle so no one notices it until now."
Souta smiled and added, "Let's go, it's quite interesting now that I saw it with my own eyes."
The group jumped down and headed toward the direction of the castle. Their goal was to free other people and stop the tamer from killing more innocent people.
'It's pretty good that there's a fourth stage monster here... But...' Souta looked at his surroundings as he narrowed his eyes.
This planet was only comparable to the mid-grade world. The mana density was several times lower than high-world so the power of a fourth stage monster here was dangerous. The concepts were weaker to the point that the cold energy from the previous forest could even freeze time.
A fourth stage could probably destroy this entire land.
Soon, the group entered inside the barrier. Aerin wanted to hide their presence but Souta simply walked inside leisurely. Eilish and the others followed him. In the end, Aerin didn't have a choice but to do the same thing.
A huge castle appeared in front of their eyes. Its height was approximately three hundred meters and there were fifty-meter walls surrounding it.
"It's larger than what I expected," Baldur muttered.
"It's reckless to simply walk in this place." Aerin sighed.
"It's fine," Souta said.
Baldur and Heimer pulled out their weapons as they stared at the gate of the castle with a fierce looks.
Aerin's expression also changed as she noticed that several people were coming out of the gate.
"They are coming."
Baldur and Heimer dashed with their weapons. Their energy exploded as both of them used their skills at the same time.
Boom!!
Their attacks swept everything in front of them, ultimately destroying the gate along with the enemies.
Aerin was a little bit surprised when she saw this. She knew that Baldur and Heimer were strong but she didn't think that they were this capable.
"Sir Baldur and Sir Heimer are strong. Only a few people could defeat them on this continent." Princess Dreimi said.
Baldur and Heimer advanced as they defeated the enemies. Princess Dreimi supported them by casting some buff spells. By the time they arrived at the door of the castle, they had already defeated more than fifty enemies.
Aerin decided to join the battle as more and more enemies kept pouring out of the castle. Even monsters decided to come out. A dozen of them were even at the third stage.
Boom! Boom!
A huge battle erupted. The ground kept shaking as powerful skills were used every second. The aftershocks of the battles swept the nearby trees down to their roots. If this battle somehow occurred in the middle of the city, countless people would die. The city would be reduced to nothing in just a minute.
Aerin swiftly moved her body from side to side, dodging all the attacks that were aimed at her. Despite her energy being sealed, she recovered a little bit of her stamina with the help of Princess Dreimi.
Still, she couldn't exert all of her strength so the only thing she could do was to take care of all of the weaker enemies.
Baldur and Heimer were fighting all the third-stage monsters.
Seeing this scene, Aerin couldn't help but be amazed at their combat prowess.
'They aren't ordinary travelers. Although their strength was enhanced by that girl's spells, ordinary fighters couldn't achieve the same feat.' Aerin said inwardly.
Baldur and Heimer continued to fight the third stage monsters, reducing the land into rubble.
Boom!!
A man stepped out on the highest balcony of the castle. No one noticed his presence as he observed the battlefield with a frown on his face.
He was the Lord of this castle, the Tamer.
"This... Where the hell did these people come from?"
Even his third stage pets couldn't easily kill all the invaders. He moved his eyes and saw Aerin.
"That elf?! So she brought her comrades here... Her helpers aren't ordinary, where did she find them?"
Tamer wondered. The people of the two warriors that were fighting his precious pets were no joke. Almost everything in this area, aside from the castle, was destroyed by the aftershocks.
"They are comparable to the higher rank soldiers of the empire. Someone at General rank. I need to deal with them now."
Tamer said as he clenched both of his fists.
'Master, should I kill them all?' A voice sounded in his mind.
Tamer slowly smiled and said, "Yeah, kill them all. The Prince will forgive for destroying this land. The Crown City will be affected."
...
Aerin watched the battle. She already finished dealing with her opponents. She hoped that Baldur and Heimer would defeat the third stage monsters.
With her current condition, she couldn't provide assistance to them.
But...
Aerin looked around and noticed that Souta and Eilish were gone. She wondered where they went at this crucial time. Baldur and Heimer needed help right now.
"Where did they go?"
Boom!!
A loud explosion occurred.
Aerin turned her head to the battlefield again. Several third stage monsters fired [Bestrou] at the same time. The attacks caused a seventy-meter-deep crater with a diameter of several kilometers.
"This power... I need to help them."
She was about to step forward when she noticed something strange.
Huh?
How?
Despite the large-scale battle that was happening, the castle stood still as if nothing happened. It should've collapsed a long time ago due to the intensity of the battle but... For some reason, it was standing still.
The aftershocks of battle probably even reached Crown City. The vibration of the ground felt like a huge earthquake occurred.
If the Crown City was a little bit closer, then a lot of its structures would collapse due to the intense shockwaves and energy pressure in the atmosphere.
If that's the case then the Tamer was still alive.
"I have to go inside and kill him."
Aerin said to herself. That's what she was gonna do if Baldur and the rest didn't agree to help her. She would try to assassinate the Tamer by herself.
But the aftershocks of the battle made it hard for her to approach the castle.
Sigh... If only they made a plan. Unfortunately, Baldur and Heimer simply barged through the gate and started eliminating all the enemies one by one.
Suddenly, a cold and sinister aura spread out from the castle. Aerin, Baldur, Heimer, Princess Dreimi, and the rest of the third stage monsters were petrified.
The aura was overwhelmingly powerful. It was several times stronger than any of the third stage monsters on the field.
"This aura... It's somehow on the same level as the being in the Cryo forest." Baldur muttered as he subconsciously took a step back.
Heimer, Princess Dreimi, and Aerin turned pale as their instinct screamed at them.
Bang!!
A gigantic head of a monster suddenly burst through the door of the castle. Its greenish eyes gleamed as the glossy black scales all over it shone brightly.
Bang!!
The entire castle slowly rose from the ground as gigantic limbs sprouted from the corners of the castle.
"The entire castle is a monster...?"
Aerin couldn't believe what she was seeing. The pressure brought by the best feram was tremendous.
She finally understood why the castle was unharmed despite having a large-scale battle beside it.
So it was a monster all along.
It was a huge tortoise called Mountain Bringer.
Ohm!
The Mountain Bringer widely opened its mouth and charged a powerful attack. The concentration of energy that occurred was like a hurricane that was about to destroy everything in its way.
"This is bad!!"
Baldur and Heimer quickly jumped away to protect Princess Dreimi. They didn't have any confidence in blocking the attack.
Ohm!
After a few seconds, the beam exploded. It advanced as if it was about to swallow heaven and earth. There's no way for them to avoid this beam.
"DIE!!!!"
The Tamer laughed as he watched his strongest pet fire [Bestrou].
BOOMMM!!!
A huge mushroom of cloud rose to the sky. The intense energy fluctuations directly killed lower beings. The ground shook heavily and it could be felt even in the Crown City.
No, the people at Crown City already saw the huge explosion. They started to panic as the energy pressure even reached their location.
It was as if the entire world was going to fall.
Cough! Cough!
Baldur and Heimer coughed as they slowly opened their eyes.
"I'm fine...? Does nothing happen? No..."
They looked ahead and saw a figure standing in front of them.
It was Eilish.
"Leave it to me... I'm going to finish this as soon as possible." Eilish said as she stared at the Mountain Bringer.
