Raff drew his two black lightning knives forward, his gaze fixed on the two giant skeleton monsters that were approaching. Raff's body instantly disappeared after the two monsters came into his attack range.

Ten black lightning bolts seemed to shoot out from ten different points, forming a ten-pointed star pattern, and the black lightning bolts cut down everything in their path. The two giant skeleton monsters at the center of the ten-pointed star pattern began to be attacked.

One by one, their body parts were slashed by the black lightning until their bodies collapsed to the ground. Raff's body now floated in the air, and the two black lightning knives in his hands seemed to have disappeared. Raff immediately pointed his palm downward, directly at the two giant skeleton monsters.

A small black bolt of lightning shot out of Raff's palm, and then the bolt split into two. The lightning pierced one of the bones in the two skeleton monsters' bodies, and the black lightning quickly spread to other parts of the bones inside the bone cavity.

The forms of the two giant skeleton monsters seemed to crumble into small pieces, but from another direction, a bright bolt of lightning shot toward Raff. None other than Electro Skullix could be seen from a distance reaching out his hand toward Raff.

A loud explosion was heard as Electro Skullix's lightning struck the tenth floor dungeon wall, scattering chunks of earth along with the flying dust. A strong gust of wind was created that hit the entire tenth floor area, the ground shaking gently as the sound of the explosion echoed.

Raff's form is now elsewhere as he stares at Electro Skullix, who is still standing on the hill. "I never knew there was such a monster in the dungeon, was he just born in this era?" he muttered.

Raff reached out his right hand, blood seemed to flow from the corner of his mouth. A giant wind dragon began to form in front of Raff, the magic of the wizard who had ambushed him on the fifth floor of the dungeon.

Electro Skullix responded by drawing both swords from his back. The ground around where Raff was standing began to tremble violently, and a wave of wind that condensed in front of him instantly shot towards Electro Skullix.

All the monsters that the giant wind dragon passed by seemed to scatter with their bodies dismembered, and the rumbling wind waves that accompanied the wind dragon caused the ground beneath it to scatter into the air.

Electro Skullix seemed to leap into the air and slashed his two swords at the giant wind dragon's magic, two lightning bolts shot out in the form of sword slashes. The lightning that shot out even lit up the area on the tenth floor.

The giant wind dragon that Raff released was instantly sliced in half in the air, and the condensed air waves were instantly released after being sliced. A violent explosion could be heard in the air, the wind waves blowing like a hurricane to all corners of the tenth floor of the dungeon.

The two lightning bolts that formed a sword slash continued to shoot toward Raff, but Raff disappeared again. A stronger explosion sound was heard as the two lightning bolts hit the ground.

Chunks of earth began to scatter in different directions, along with pieces of the monsters' bodies that were affected by the explosions. The scattered dust began to envelop the battle area. Electro Skullix immediately stepped on the ground beneath the mound, and the ground he stepped on seemed to scatter.

Raff's form was now behind Skullix, the black lightning knife seemed to be tightly gripped by Raff's right hand. Meanwhile, Raff's left palm was extended forward toward Skullix's back.

A very thin black bolt of lightning shot out of Raff's left hand, but the lightning on Electro Skullix's back immediately responded by hitting Raff's attack. There was a collision in the air as Raff's attack hit the lightning on Skullix's back, the lightning on Skullix's back seemingly unable to be contained by Raff's small black bolt.

Raff was forced to clench his fist again. The lightning from Skullix's back quickly went straight to Raff, who immediately stomped his feet and dodged Skullix's lightning.

The sound of an explosion was heard as the bolt from Skullix's back pierced the hill where the skull chair was, Skullix's attack reached the other side of the hill before finally stopping. Another bolt of lightning was aimed at Raff, who kept running to avoid Skullix's lightning attack.

The sound of successive explosions could be heard as Skullix's lightning struck the ground. Raff continued to run and jump, dodging each attack that came his way. Skullix immediately turned to Raff and swung his two swords to slash Raff.

Raff's figure disappeared again as Skullix's sword hit the ground. Raff was now behind Skullix again as he quickly slashed his sword at Skullix's left leg, but the lightning bolt on Skullix's back responded by attacking Raff in turn.

The sound of impact could be heard as far away as Hayato and Sonia. Successive waves of wind continued to blow strongly towards them, their expressions clearly showing their shock. For an adventurer of rank F could take on the monster Electro Skullix.

"Am I dreaming? This is unbelievable," Sonia muttered.

"I knew he was good, but I didn't expect him to get this far. What kind of training did he go through to be so strong with limited mana?" wondered Hayato.

Several monsters seemed to be approaching the two of them, but most of them collapsed as soon as they got close to Sonia, who was standing at the front. In the distance, two huge skeleton monsters approached with swords drawn.

"They seem to be different from the usual monsters," Sonia said as she stared intently at the giant skeleton monsters in the distance.

"They are monsters on par with B-rank adventurers. Beware, their physique is very strong, even though they can't use magic, their physical strength is probably several times stronger than a B-rank adventurer," Hayato said while gripping his sword tightly.

A skeleton monster immediately swung its bone sword at Sonia, but Sonia skillfully used her shield to deflect the monster's sword. The sound of a loud crash was clearly heard from the clash of their weapons, even Sonia's legs were pushed back by the force of the skeleton monster.

The dust around Sonia's feet was also blown away by the wind waves from the clash of their weapons, Hayato tried to slash his sword into the air. Three waves of fire shot towards the giant skeleton monster, Hayato's strike hit the skeleton monster's sternum.

"Tch. In the end, it will always be like this," Hayato grumbled when he saw that his attack only scratched the skeleton monster's bones.

"Their movements are slow, but their power is very strong. If only they had some sense, they'd be hard to beat," Sonia thought as she stomped her shield forward.

The giant skeleton monster's body was pushed back slightly, but another monster swung its sword at Sonia again. This time, Sonia chose to dodge while running forward towards the giant skeleton monster's body.

A loud crashing sound was heard as the skeleton monster's sword hit the ground. Sonia immediately jumped into the air and tried to catch the monster's thigh bone, Sonia knew that her passive skill was more effective at close range.

But a surprising thing happened, a bone suddenly appeared from the thigh bone of the skeleton monster. The bone shot out to greet Sonia's floating body. Sonia quickly placed her shield in front of her, and using protective magic, a pitch-black colored wave appeared, enveloping the shield in Sonia's hand.

"Darkest shield!" said Sonia.
