The Isekai Adventure System
Extermination !

Sven's fight against King Bonelo and King Welfy had managed to make Sven seriously injured and overwhelmed Sven.

They both have high speed and considerable strength, actually Sven can beat them easily if the fight is one-on-one.

However they did not let that happen and continued to gang up on Sven relentlessly, therefore Sven became difficult and overwhelmed against the two of them at once.

Now Sven looked serious and frowned which meant Sven became angry and upset at the two of them.

Then Sven added his God Speed speed by increasing his electric and wind element magic that surrounded his entire body by 10x fold.

After adding and increasing his speed to it, Sven instantly tried his hand and directly attacked the two of them.

That speed managed to make the two of them unable to see Sven's movements because it was so fast.

Sven suddenly got behind the Welfy King and directly punched the Welfy King's back head very hard and threw him tens of meters away.

Sven plans to kill the Welfy king first because he has a skill that makes Sven quite difficult.

After the Welfy king was thrown away, then Sven chased after him and would continue his next attack and not make the Welfy King to rest in the slightest.

King Bonelo could not help the Welfy king who was being tortured by Sven because Sven's speed could not be seen by him.

"His speed is equivalent to that of a demon general !!..." Said King Bonelo in a panic.

Three minutes later Sven defeated the Welfy King, and Sven threw the body of the Welfy King towards King Bonelo.

"Sorry your friend is not moving..." Sven.

Seeing that King Bonelo made his feelings jumbled between sad, fear, panic, anger and resentment that made him go crazy.

King Bonelo could not express her feelings of being seen by the corpse of the Welfy king.

As Sven saw King Bonelo's reaction to being like crazy, Sven was unwilling to waste the opportunity and would directly attack him.

Although King Bonelo was hit by a blow from Sven, but he King Bonelo did not want to fight him and he wanted to escape because of fear of Sven.

Then King Bonelo used his mysterious skill which he suddenly went into the ground and instantly disappeared.

"Curtain!.. Escape yes !!"

"Bas a coward !!..."

Sven had managed to kill two of the demon king's pets namely the King Of Dragon and the Welfy King, and all that was left of the ten demon king's pets was now eight more.

*Quest Rank SSS+ (Completed).

- 1,000/1,000 black demon horns.

Sven will return to the city of Grundene and will leave this demon country, before that Sven will rest inside the demon forest to heal his wounds first.

A few days later the wound was almost healed by about 95% and just waited for some time to return 100%.

As Sven was relaxing inside the demon forest suddenly Sven felt a strong killing intent from a distance and he instantly prepared to face him.

Sven already holds two of his strongest weapons at once, namely the Cleric Battle Mace (CBM) and Spiked Knuckles, because his health condition has not been 100% healed completely and he will finish it quickly.

A few minutes later, several monsters appeared that looked strong, then Sven saw King Bonelo there and Sven immediately analyzed them one by one.

1.King Ertozof (King of the Earth)

2.King Greeney (King of the Forest)

3.King Waterez (King of the River)

4.King Slimo (King of Slime)

5.King Bonelo (King of the Skull)

There should be eight pet demon lords left, but the ones who came to Sven were only five.

"Hoy!! Ugly skull! why don't you take all of them ?!..." Sven asked King Bonelo.

"Whispering!.. You're gonna die now!!.." Reply Bonelo

Sven put his two weapons back into his magic bag, then Sven activated his Impact Counter skill.

Sven was forced to use his Impact Counter skill as he fought against the six pet demon kings though.

Therefore if he does not activate his Impact Counter skill he will lose.

After activating his Impact Counter skill Sven directly attacked all of them at once with his Elemental Wizard skill that took out Blizzard Storm and Thousand Needle Ice.

Sven knew that his skill would not hurt them in the slightest, he simply bullied them all to make them all attack Sven simultaneously.

The plan almost succeeded to make them all attack simultaneously, but the only thing that attacked Sven was King Bonelo.

King Bonelo attacked Sven by throwing a reaper scythe at Sven, and the scythe bounced back to King Bonelo very quickly and split his body.

Sven knew that human skulls could regenerate quickly, so Sven immediately beat him up by taking out his CBM weapon that released white fire elements and immediately burned Bonelo's king to ashes.

"One is dead!!.. Come on, all of you!!!.." Sven.

Now there are four creatures left in front of him, King Ertozof, King Greeney, King Waterez, King Slimo.

Sven who activated his Impact Counter skill was intending to kill them all at once.

King Ertozof the earth king attacked Sven by locking his body with the ground, and King Greeney the Forest King whipped hundreds of poisonous root whips, then King Waterez King of the River was according to Sven's head with water to make sven difficulty breathing and the last King Slimo King Slime released a sticky poison liquid that enveloped Sven's body.

All of them attacked Sven simultaneously in their own way, suddenly they all felt pain and stopped their attacks.

They were unaware of Sven's Impact Counter skill that could reflect and return their attacks.

Which meant that if they attacked Sven with all their might, then they had attacked themselves.

Fortunately they were all stupid and came back to attack Sven blindly and barbarically without stopping.

They attacked Sven with all their might and took out all of their strongest skills continuously without stopping.

Suddenly King Ertozof spewed blood from his mouth and his eyes turned white as if unconscious.

Not only was King Ertozof suddenly injured, but one by one they were all also uprooted and dying from their own attacks.

In just 10 minutes, they all looked badly injured and dying.

Then Sven who saw that instantly killed them all without a single one remaining.

Sven had already counted the number of pet demon lords he had killed from the king of dragons until now.

The three pet demon lords are King Troy, King Cthulf and King Aperof.

"Luckily I activated the Impact Counter..."

"If no.. Maybe I'm dead..!"

"This demon country is crazy!! they're strong!!..."

"I have to go back to the city of Grundene first.."

After that Sven returned to the city of Grundene immediately, because otherwise Sven would continue to be hunted relentlessly by the devil king's men.

So Sven will rest in the city of Grundene.

As Sven was already in front of the door of the demon magic portal that was heading into the city of Grundene, Sven suddenly felt an immense and powerful killing aura pressure.

Sven's facial expression turned pale and frightened to the point of breaking out in cold sweat and making his body tremble in fear.

"Damn!!.. What pressure is this !!..."

"I don't want to die, I don't want to die !!!!.."

"I have to go.. I have to go !!!.."

Sven first felt such a real fear and felt like he wanted to escape immediately.

Moments later Sven finally made it back safely to the town of Grundene with a very frightened face.

Who could give off such a terrifying aura and give off such an enormous and powerful killing aura ?
