The Isekai Adventure System
The Thousand Of Black Demons !

Darko has become a fugitive of challenger black demons, because Sven himself is the one who challenges them blatantly and makes them become angry and hunt him down.

But Sven became delighted and excited at what they had done that made the contest and the fugitive paper they spread.

Now Sven is still a crow that is up to the roof of the city while looking at those who are busy looking for Sven.

Then Sven changed his form to Darko the black devil who immediately shouted with a loud voice on the tile.

"Hoy!!.. I'm here..!!"

Simultaneously the black demons within the city instantly took out their weapons and prepared to face Sven.

But the number of black demons looked a little about 20 or 30 demons alone.

"Bring up your many friends or chief !!!"

"Because I am the future demon lord !!!..."

Said Sven who was lying and was provoking them.

After saying that, there were some black demons who ran or went to call their friend or their leader.

And there were also those who were confident to attack Sven himself.

Those who attacked Sven one by one died and became ashes in an instant.

Some of those who saw him immediately ran in fear and would ask for help from the other black demons.

"Yes!!.. Run and bring your friends all!!"

In the city it instantly became desolate as the black demons ran in a daze of fear who saw his dead friend in an instant and became ashes.

"Ah now be deserted..."

"Well, now I want to eat first.."

Sven saw the citizens of the red and black demons who were in the city look frightened to see Sven, they closed their store.

But Sven forcibly opened the bar shop for drinks and food, because he was hungry and wanted to rest for a while while waiting for the challenger demons.

Although Sven forcibly opened the store to eat and drink, he still paid for his food and was not free at all.

Two days later Sven, who was relaxing and lying on the tile, suddenly heard the sound of footsteps from a distance that shook the ground.

Sven instantly used his Wizard Form skill which transformed his form into an eagle and instantly flew up and used his eagle eyes to see what was happening.

It turned out that the sound of footsteps that shook the ground was an army of black demons that numbered in the thousands and looked like they were going to war.

Sven headed straight towards them and immediately used his Wizard Form skill which changed its form into a dragon king which was King Of Dragon.

With its enormous size and seeing thousands of black demons it looks like a collection of dwarves only.

Arriving at Sven in front of the thousands of black demons, he immediately spat out a purple flame that had a very large area.

However there were some black demons that could use protective magic like "Dark Shield, Cube Protection, Black Barrier".

And Sven's attack could only injure a few of them, thanks to their protective Skill it could reduce the number of casualties.

With the form of the King Of Dragon that is very large it sven utilize it by trampling with its dragon legs are so large.

The physical attack that Sven did was successful in injuring them more than before. When Sven was scrambling the formation of thousands of black demons with his King Of Dragon form, suddenly there were two mysterious creatures that were very strong and managed to make sven retreat.

The two powerful mysterious creatures looked like a skull man and a werewolf, and Sven analyzed them both.

*King Bonelo!

king Bonelo is one of the demon king's pets, he has the strongest skull-faced man among all other skull humans whose essence he is the king of skulls.

\*King Welfy

\-King Welfy is also one of the pets of the demon king, he is the king of the werewolves.

Sven who was looking at his status screen system made him remember something about the pet demon king that he had previously read about in the status screen system.

1.King Droy (2 Meters)

2.King Cthulf (300 Meters).

3.King of Dragons (100 Meters).

4.King Aperof (90 Meters).

5.King Ertozof (?).

6.King Greeney (17 meters).

7.King Waterez (?).

8.Slimo King (7 Meters).

9.King Bonelo (3 Meters).

10.King Welfy (6 Meters).

Sven had once managed to kill one of the pet demon king namely King Of Dragon and now had appeared two pet demon king who was fighting sven.

Then Sven again changed his form to Darko the black devil to minimize the attacks of the two previous demon king pets.

Because the form of King of Dragon is too large it becomes easy to be attacked by those who have a considerable strength.

Therefore Sven changed his form into a black devil of the same size as them.

Now Sven would ignore the two demon lord pets and plan to slaughter those thousands of black demons first.

Then Sven used his Elemental Wizard skill which released electricity and wind and he flowed both elements throughout his body to accelerate his movement and speed and Sven named the skill "God Speed!"

God Speed!!.. Said Sven who immediately ran with ordinary breadth quickly like a flash of light.

With that extremely high speed, Sven managed to slaughter hundreds of black demons with his CBM weapon.

Then Sven increased the power of his magic element of electricity and wind to make his speed 3x faster than before and made the black demons unable to see Sven in the slightest.

With the speed of his god it had managed to kill the entire black demon that numbered in the thousands within 1 hour only.

After finishing slaughtering thousands of black demons it sven immediately drank a few bottles of stamina and power-enhancing potions.

And now there were only two pet demon lords, King Bonelo and King Welfy. Sven did not want to talk and did not want to waste any more time.

Sven immediately attacked Welfy and Bonelo at once who hit his kicks and punches on both of them.

His speed could still be agitated by the two of them quickly which meant Sven's speed could still be seen by the two of them.

Then the three of them were fighting with the same speed and the same strength as well, the fight made Sven difficult because he was fighting two kings at once.

Despite Sven's difficulty and a bit of overwhelm fighting the two demon king's pets, Sven will still fight them without using the help of his armor set and not activate his Impact Counter skill.

Their fight had been going on for hours without stopping and looked extremely fierce.

Suddenly Sven was hit by a hard kick that hit his stomach, and made Sven completely overwhelmed.

Sven's condition looks exhausted and get quite severe injuries due to their attacks.

Then Sven's countenance looked furious and Sven was doing something to avenge their attack.
