Split up

When he went through the portal, Joseph wondered if he should start a guild or let his wives make parties or simply go around and get some new sluts to bed and wed. But when he opened his eyes, he would be sorely mistaken to think that he would get to explore this world so easily. Because when he opened his eyes he was not the man with 13 wives but instead he was a tentacle monster in some birthing pit. He had 1 eye surrounded by a bunch of pink tentacles and that was it, he could feel the mouth under the eye and excitable substances in his tentacles but he knew he wasn't human or anything remotely similar. It seemed that in his unpreparedness to enter this new world, he didn't expect Fantasia to turn him into a monster.

Deep in thought, Joseph was startled to hear his system prompt, seeing the bright pink screen have a different font and colour along with a design like a holographic letter. When he opened the letter that looked like it was made when people still believed in dragons, he realised what was happening, Joseph had awakened a dual system. Unfortunately for Joseph, because he was a monster the system quickly changed after realising his existence, transforming from the Hero system to the Demon Lord system.

Demon Lord system:

Class: sacrificial mob

Species: Newborn lowest-ranked tentacle monster

Defeated enemies: 0

Ongoing missions: Defeat current Demon Lord

With this ambiguous system, Joseph wondered what each option did or helped him do, thinking about how his other system gave him a stat point for every woman he added to his harem.

Demon Lord system info:

Class: Changeable using a 'job change stone' or by killing the creature with the job you desire

Species: Race the player currently exists as which can be changed by using kill karma or consuming other creatures

Defeated enemies: Replaces levelling system by creating kill karma which allows the user to upgrade their form

Ongoing Missions: Defeat the Demon Lord: Kill the Demon Lord to take his class and fully awaken the system

After understanding the information, Joseph tried attacking another tentacle monster who was just born, and though it was a fierce fight, he managed to kill the creature. Joseph was amazed at how weak he had become but tried to focus on other things, seeing how his kill count increased by 1 and allowed him to grow less than a single percentage of an inch. He knew it was going to be impossibly long before he could return to his strength so he kept doing as he was doing, killing and fighting. Before he knew it, months of killing and eating his kin passed, growing into a feared existence amongst his brethren, looking like he was the size of an adult. To the mindless monsters, this was enough as they tried to mate with him, not caring about how his skin didn't even begin to peel to a darker texture, as is the genetic effect for maturing. Joseph, who had spent so long without the loving companionship of his family, couldn't help it, he allowed the monster the shove its tentacles in his and vice versa, releasing his juices while their mouths allowed their tongues to smack and twist one another. That is when Joseph got the notification:

Defeated enemies: 1

Joseph was surprised and ecstatic to realise that he didn't need to spend an outrageous amount of time killing and could fuck his way to glory. He began fucking all the other tentacle creatures he could, regardless of if they were bigger or not, stronger or not, he kept going at it until he fucked his way to the boss room of the cave. He got the kill karma all the same and because of that, he was now able to face the boss tentacle monster who had been gaining in strength while the cave went unnoticed thanks to Joseph killing all the other tentacle monsters, stopping them from pouring out and causing problems, unknowingly saving his bacon. But that was then and now after he had sexually defeated the boss and killed all the other tentacle monsters that came before him, including the boss, his defeated count was at 3000. As for the tentacle monsters that came after, they reproduced fast, coming out of Joseph's tentacles and the tentacles of the monsters he killed. Quickly, the numbers of the cave went from 2000 weak monsters to 10,000 strong monsters who harnessed Joseph's improved genetics that were altered thanks to the kill karma. It got so bad that all the other monsters in the forest were overwhelmed by the tentacle monsters who rushed like a tide, turning creatures into food that empowered them (for a short burst) or breeding sacks. It wasn't long before a subjugation order came down and when it eventually did, Joseph was gone, long since fleeing the cave after leading these monsters around to kill and fuck personally. But he didn't grow any larger, instead, Joseph harnessed the kill karma he had stored up to create a cocoon, later popping out in a new form before he ran away.
