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

With a fireball formed of the Fire Powerhouse's compressed Fire Energy, Adam suddenly disappeared from where he stood, and appeared behind the Fire Powerhouse.

His movements were instantaneous thanks to the Step Skip Skill and there was no way to avoid the attack, if Adam attacked him with the fireball, but he wasn't looking to kill him. Instead, he kicked the side of his head with an explosive high kick, then followed it with another kick from his left leg that flung him up into the air.

Then using the Step Skip Skill, he used the same two kicks on both the Sword Powerhouse and the Speed Powerhouse, leaving them all dozens of metres in the air and barely conscious. With all of them in the air at once, Adam flung the explosive fireball he had in his hand at them, and timed it so that it hit them all at once.

The three Powerhouses of the Black Dragon Gang that never believed that anyone other than their boss would be able to defeat them in their region, had been decimated with ease by Adam.

They were launched flying in three different directions and had all not only lost consciousness, but also suffered bad burns all over their body and internal injuries from the force and impact of the explosion.

The gap in power, capability, skill and experience was too large, and Adam had ended them in the blink of an eye, before turning to the rest of the Black Dragon Gang members, who were too afraid to even look directly at him.

"Bring me their bodies and you will all be obedient to me, not acting without my permission," he ordered loudly and domineeringly, using both his Charm Skill and King Ring to make them subservient. 

They found it hard to breathe under the powerful pressure that his King Ring bore over all of them, while they were also already willing to serve and obey him after seeing his power, but the Charm Skill just made it so that they had no choice to.

Using both the King Ring and Charm Skill made it so that controlling people, and even animals and beasts became easy. The King Ring would allow him to dominate them and crush their will, while the Charm Skill would then make them willingly follow and serve him.

However, the stronger someone was, the more power he would need to unleash through the King Ring and also the more energy the Charm Skill would require, which took its toll on his body. 

For that reason, and because his King Ring and Charm Skill's power seemed to be dampened in the dungeon, he didn't use them to complete dungeons, however, when in reality, they were definitely useful tools at his disposal.

Within seconds the bodies of the three Powerhouses of their gang had been carried over to Adam by some of the Dragon Gang Members, while the others all stood before him with their heads lowered.

"Now then, where is your boss?" asked Adam, but none of them seemed to know.

No matter how hard Adam tried, he couldn't sense any powerful presence within the troops of the Black Dragon Gang, but he was looking in the wrong place.

As he stood there, Adam was thinking about what other ways the boss of the Black Dragon Gang could conceal himself, sure that he would come to join the battle after his most powerful subordinates were taken down and all of his men became obedient to someone else.

However, suddenly, he sensed danger coming from below him, which was unusual, but he trusted his instincts and jumped away. To his surprise, it was a person that had unexpectedly burst up out of the ground, and immediately, he was recognised by the Black Dragon Gang Members.

It was their boss. The man famed for his Earth Elemental Affinity and combat prowess, along with being ruthless and cruel.

"Impressive. You took down all four of my Powerhouses, along with killing one of them. While you also somehow managed to take over my gang and make them all obey you," he said as he suddenly unleashed his powerful aura, thinking that maybe it would intimidate his troops and get them to obey him again instead of Adam.

However, his aura was nothing compared to what they had experienced when Adam used the power of the King Ring and the Charm Skill. Seeing that his men didn't react or seem to be affected by his aura, he was shocked, but also furious that the troops he had nurtured and gathered were no longer loyal to him.

"You dare to betray me, I will slaughter you all if you do not bow before me," he bellowed as he unleashed a thick and frightening killing intent.

Remembering what they had seen and heard their boss do and not wanting to go against him, they all turned back to their boss and bowed before him, believing that he would be able to overpower Adam.

Seeing that, he scoffed and was going to punish them to make sure they weren't so easily swayed again, but before then, the one that was a thorn in his side needed to be eliminated.

"All of you, get out of here and you all serve me and listen to me," ordered Adam, unleashing a great power from his King Ring and Charm Skill.

"Forget about your past master and carry anyone unconscious back to the city, then await further instruction. If you dare to disobey me, I will make sure you all die," he added, but with a killing intent that was even more powerful than their boss.

This time, Adam had completely removed any previous allegiance or loyalty they had for their boss as they immediately began doing what he said, rushing back towards the city to get out of their way.

Which left Adam facing off against the amazed, but enraged, boss of the Black Dragon Gang, who had just lost all of his subordinates.
