The Isekai Adventure System
Demon king's cunning ways!

The demon kingdom or Demon Kingdom has been successfully combed and cleared by Sven, but he does not find a demon king there, because the demon king has fled away from Sven.

The demon lord could measure the strength between himself and Sven who was still too far away and too strong to face directly by him, therefore Luc III the demon king will continue to avoid and stay away from Sven.

The black and red demons again appeared even though they had been slaughtered and destroyed by Sven. For the devil will not die if it is not burned by the white fire or the light of heaven.

Sven knew it beforehand and he was forced not to kill those who just separated and cut off their hands and feet so as not to move and not to come back to life.

Sven had searched for days for the demon king in this kingdom and had not found him, and the next day he teleported to every member of his that he positioned in every kingdom.

From the start of teleporting to Shenlong who was in Ragas kingdom to the end of the fairy Kingdom kingdom he had come to hear the latest information from the movements of the demon lord.

All his information was the same all that was only approached by a few giant monsters and did not get about the information from the demon king.

Sven ordered them to remain on alert and continue their guard in every kingdom.

The sweeps Sven did every day that only found hundreds of monsters were constantly coming to the entire kingdom without stopping.

The cunning demon king who only used pawns and still did not move it made Sven upset and angry at him.

Fortunately Sven and his members had above average strength that could defeat tens or even hundreds of monsters like killing flies.

A few months later.

Sven met his younger brother Sveinar while he was slaughtering and combing monsters in a forest in the Ragas kingdom.

The meeting of the sister and brother looked very happy who were telling the story of their adventures with each other and told the sister about the movement of the demon king and the current situation.

While Sven and Sveinar were chatting and conversing, the demon lord was watching and monitoring their conversation remotely using his demonic eyes.

After the demon lord saw that, he immediately smiled and suddenly disappeared somewhere.

Sven invites his younger brother to join in the sweep of the monsters ordered by the demon lord to attack all the kingdoms.

However Sveinar refused her, because if she continues to be with her brother, she feels it will not get stronger because all the enemies will be killed instantly, so he didn't get a chance to raise his Strength.

Sveinar wants to try to be strong like his brother by adventuring alone without anyone's help.

Such is his desire that has its own purpose, Sven understood with his desire because he had also been in his position when he was at the same age as his sister.

The two of them split up and will return to his duties to find the demon king Luc - III.

It has been two months, the demon king still has not appeared and has not done any action that only uses his pawns continuously.

Sven had to wait and wait for the demon lord to appear.

But more and more monsters are coming to every kingdom, from the beginning which numbered in the tens and hundreds of monsters, now the monsters come and attack every kingdom with twice the amount of before.

Although their numbers continue to increase and more every day, it is not a problem with Sven, but it will make it difficult for members who have limited stamina, and unlike Sven who has unlimited stamina.

Sven worries about his members being constantly attacked by monsters that continue to multiply every day and begin to make all its members overwhelmed because of the limitations of their stamina that is not given the slightest rest.

Sven really had to find the demon lord to stop the monsters from coming and attacking every kingdom.

Luc-III really makes Sven very upset and angry at him who is cowardly and does not dare to bring himself that.

Now Sven must patrol very quickly from Ragas kingdom to Fairy Kingdom kingdom by using his Teleportation skill and help all members of The OFS family who are on guard in every kingdom.

Seeing Sven who was so trying and struggling made all the gods come to his aid.

With the help of the gods it makes Sven very happy and lighten the burden of his work that every day pacing and back and forth from one kingdom to another without stopping.

Now Sven becomes more focused with his quest that searches for the location and whereabouts of the demon lord thanks to the direct help of the gods.

The demon king's quest to stop the monsters that are moved and ordered by the demon king and must also kill him to stop the next crimes.

Little by little sven began to know the routes and movements of the demon king who hid from one hiding place to another hiding place one by one.

With his Teleportation skill it made it easier to chase the demon lord.

Within a month, Sven was finally confronted by the demon king Luc-III in a mysterious place in the demon kingdom.

Sven did not want to negotiate or talk with him, he immediately beat the demon king with his fist that hit the demon king's stomach to thicken it hundreds of meters away.

His fist made a hole in the demon king's stomach, then Sven used the Disable Power skill to disable the demon king's regeneration.

LucIII really could not fight Sven in the slightest as he thought that Sven was too strong to fight now, but the demon lord was no longer able to escape.

Luc-III finally pulls out his final evil trick to save himself from death.

The last trick is to call Sveinar who has been brainwashed into evil by giving or mixing his food with black meat on Sveinar while Sveinar was eating some time ago.

Sveinar looked empty and his eyes turned all white because he had eaten the demon lord's black flesh.

Sven tried to resuscitate his brother from his unconsciousness, but his efforts were in vain because now Sveinar was unconscious and only obeyed the orders of the demon king.

Sven was really angry at Luc-III who had brainwashed his sister to such an extent.

Just as Sven was about to kill the demon lord who was heavily injured and was already unable to move in the slightest, his attack was suddenly fielded by Sveinar.

Sveinar always held back and repelled every attack of Sven that led to the demon lord.

Now Sven understood that the current Sveinar would only protect the demon lord from any attack.

Sven is forced to fight his brainwashed sister, if he wants to kill the demon king who is seriously injured.

Sven's fight with his sister was about to start and face each other!
