Boom!

The two ships that were waiting outside the cave felt the fluctuations of energy. Alarms quickly sounded inside the ships and the people moved the ships away.

The next thing that they saw was the whole cave collapsed. Huge cracks spread out before the whole place crumbled down.

Boom!

After a few moments, something exploded from the inside as the boulders of rocks were blown away. The boulders flew in every direction and lightning shot upward in the sky.

The people inside the ships were shocked when they saw this scene. They couldn't understand what's happening but then they couldn't retreat as the leader of their operation was inside the cave. They knew that Souta's power was godlike and something like this wasn't enough to kill him.

After a few seconds, another explosion burst out of the ruined cave. Souta emerged out of it along with Isabella, the experimental subjects, and the toxinum goblins. All of them were being protected by a gravitational field that Souta created using the [Gravitational Ball] spell. Of course, he didn't forget the people with them.

As for the rest of the creatures inside the cave, all of them were buried alive. They would simply die down there.

Souta had a serious expression on his face. He realized that the man in front of him was no joke. This was a powerful man maybe at a general level.

He waved his hands and the gravity field moved away. He didn't want the people that he rescued to die because of his battle. These creatures were weak and the aftershocks from the upcoming battle could greatly injure them.

"Souta!"

Isabella said as she glanced at Souta. Then, she turned her head on the two ships.

The sun was still at its peak and once she moved away from the barrier that Souta created she will felt the intense heat. It's dangerous to go outside in this extreme environment.

That's the reason why she couldn't go back to the ships. Isabella glanced at the experimental subjects and the goblin tribe.

The experimental subjects were unconscious. They didn't even know that a battle was going to erupt at any moment. The battle that will decide their fate.

While the goblin tribe was stunned, shocked, and surprised. Their mind couldn't follow what's happening. The ground collapsed and in the next moment, they found a barrier protecting their lives. It was too much for them.

The unknown man was looking at Souta with a serious expression. "That's a dragon's energy... How can you use it?" He was inwardly shocked when he felt it.

"Why people from this world are always asking me how can I use a dragon's energy? Damn! This energy isn't unique to a dragon." Souta said with an annoyed tone. He didn't immediately attack as he was curious about his opponent.

"Oh? Are you a researcher too?" The man raised his eyebrows when he heard Souta's words.

"No, but this is just basic information and a lot of people knew about it. Dragon's energy is called beast energy or best feram. All monsters had to ability to utilize this energy once they've reached the third evolution stage." Souta said as he shrugged his shoulder.

"Third evolution, you say? Until now we haven't found any monster that reached the third evolution stage in thousands of worlds that we conquered." The man was amused so he explained.

"Of course, all the world that your empire had conquered are just low-level world. People also called it particle world. The particle world has the lowest level of mana density in the whole universe and the resources in this world are scarce. So it's natural that the monster couldn't reach the third evolution stage. They don't have enough materials for their evolution." Souta smiled as he explained what he knew to this man.

The knowledge of a person who came from Imperium far surpassed the knowledge of a man from a particle world. Well, that's just the basic knowledge in Imperium so it's understandable.

Still, he felt good showing a researcher that he knew a lot of things.

"I'm going to introduce myself to you." Souta chuckled before he continued, "I'm Souta Ieshi, I will be taking over this world and I will end your life."

"Hmph! Big words, try it if you can!" The man snorted. He was still thinking about the particle world. If what Souta said was right then there were countless worlds that were more powerful than them.

Swoosh!

Souta launched himself forward and threw a punch at the man. "Don't think about what I say to you? Your level is too low before you think that you could conquer those worlds..." He said as shockwaves flew out of his fist.

Bang! Bang!

The man controlled lightning. The lightning spread out and it collided with the shockwaves that flew out of Souta's first.

Boom!

Souta smirked as he chased after the man who had the power of lightning.

Boom! Boom! Boom!

Two figures collided in the sky repeatedly causing powerful shockwaves.

The man was getting pushed back and he already suffered injuries in his body. The overall strength of his opponents was higher than him.

Souta's speed, strength, toughness, and energy level were higher.

"Haha! I will take your body! I want to know how can you use the dragon's energy!" The man laughed while looking at Souta. Blood dripping out of his mouth.

"It's impossible. I'm not a human or a demi." Souta said to the man.

The man gritted his teeth and lightning burst out of his body. He rushed towards Souta with astonishing speed.

Swoosh!

"You've intrigued me. I will chase you and I will not stop until I take your body to my laboratory." The man said while throwing lightning whips at Souta.

Souta swiftly moved his body as he avoided all the lightning whips. He simply looked at his opponent and said, "You don't believe other people's words. Instead, you only believe your own research."

"Hahaha, I will use everything just to take you back..." The man laughed madly as he opened his arms widely and the lightning sphere exploded.

Boom!

The lightning sphere expanded and Souta simply pushed his arm forward to create a hole in it. The lightning danced wildly in every direction and it destroyed everything in their way.

Souta flew towards the man while ignoring the lightning around him. This level of lightning couldn't injure him. Still, he was taking damage but it's not that high because of his various resistance at a third evolution monster.

He slowly pulled out his sword and he gently thrust it forward.

[Stab]!

His movements were slow but his attack contained heavy power that dispersed the lightning field.

Bang!

"What?!"

The man was shocked as he couldn't believe that his lightning field was defeated just like that. Souta's attack was simple yet the power behind it was overwhelming.

"Told you. You can't do anything to me." Souta said in a cold tone as he once again thrust his sword forward.

Swoosh!

"Nooo!!!!"

The man shouted as his body was being torn apart. The force behind Souta's attack was tearing his flesh and he couldn't do anything about it. He wanted to move his body to avoid it but he realized that the gravity was crushing him.

"This is not the end!! I will remember your face!! I will discover the secret in dragon's energy! The empire will hunt you down!"

These were his last words before his body disintegrated.

"Hunt me down? I'm already the empire's greatest enemy..." Souta muttered as he turned around. He didn't care about the empire hunting him down. He already conquered the Prison World and destroyed their bases there so he was their enemy.

...

Souta gathered the experimental subjects in the ship. He asked some of the people there to take care of them. Isabella helped in taking care of the experimental subjects. These people suffered in their life.

The empire was researching about the parasite and he learned a lot of things regarding the famed parasitic essence eater.

His quest wasn't complete. He just destroyed one facility and he needed to destroy as many as he could before he could complete this chain quest. The special quest will end once he completed the chain quest.

Also, the special quest wasn't about destroying the facilities. He needed to rescue the people that were being experimented with too.

He was really glad that he triggered the special quest in this chain quest. He thought that he wouldn't trigger it anymore. In Lumilia's chain quest, the special quest that he triggered in that quest was to fight and defeat Gregory in a battle.

Still, there's something special about that researcher that he killed.

Souta looked at the sky as he narrowed his eyes. He was sure that he killed that man but his instinct was telling him that man was still alive. He looked at the number of souls in his earring but he couldn't recall if it increases or not.

Most of the time, the skill of the earring was activated so the earring would automatically sucked a soul in the surrounding. It would only notify him if he filled the soul requirement.

He only deactivated it if he was inside a city in case there's a god-level powerhouse monitoring the city.
