Series: System Universe
Author: SunriseCV (8 books)
Series status: Ongoing
First published: August 26, 2020
Description: Years ago, Earth was indoctrinated into the "System."
Earth was not the only place with the System, however. With the System came the other races, Invaders. The Invaders had one goal, to obtain ownership of this new habitable planet. This created a bloodbath, and for years the war raged.
This didn't really have much to do with Derek. Derek was kind of a loner. Yeah, he enjoyed the occasional chat or drink with others, but he never stayed in one place too long or really got to know anybody new.
Derek did happen to be rather strong. After the years of fighting monster and Invaders alone, he had become quite adept at surviving. One thing that helped keep him alive was his refusal to get involved with others. He rarely cooperated with teams.
One day, Derek broke his rules and decided to lend some help, as the mission didn't seem too hard. He should have stuck to being alone.

Description: Fight, survive, adapt, and rely only on yourself.

That is Derek’s creed, and what's got him through the System Integration on Earth.

Everything changed when the System came. Cute bunnies and beautiful butterflies became savage killing machines. Then the Invaders arrived with a single goal: to obtain ownership of this new habitable planet.

War has raged ever since.

None of this mattered much to Derek, aside from making living a little more perilous. He mostly kept to himself. He was the weird guy who owned a cabin that occasionally came into town for a drink and light conversation. After System Integration, that didn’t change much—he only got stronger.

After years of fighting monsters and Invaders alone he’s become quite adept at surviving. Who needs others to get in the way or worry about?

Until one day, Derek goes against his better judgement. He decides to lend some help on a mission that doesn’t seem too hard… He should have stuck to being alone…

It’s not easy being a System Traveler. Well, the traveling part is hard, at least.

Description: So… the first city he traveled to on a new world wasn’t exactly what he expected...

House Gracefall wasn’t anything like what Derek had imagined it would be. Instead of rage and anger at the loss of one of their young masters, House Gracefall showed humility and even apologized.

Despite one noble house exemplifying honor and nobility, another awaited to reinforce the negative stereotypes that Derek had been anticipating all along. Somehow, out of all that, Derek made a new friend, a new business partner, and learned some secrets, while Silvi got her first taste of the real world of cooking...and loved it.

With his success rate of meeting nobles being at fifty-fifty, Derek and company have now ventured forth to a new city. What will await them there? What are the odds that he can go two for three on noble families? Will Silvi get her own kitchen?

He plans to answer these questions and more as he and his companions enter Savannah, the business capital of the Cydarian Kingdom.

Description: He didn’t know he was looking for a home until he found one.

Savannah was unlike any city Derek had ever been to. For the first time since his arrival in Cydaria, Derek actually met a respectable city lord. Natalie Savannah and the city she ruled were much more than he’d imagined.

With this combination, Derek made the decision to put down roots by building a shop from scratch and moving his people in. He was even able to get Silvi the beloved kitchen that she so desired, along with personally meeting Alanah Swan and learning new things about the new system he was thrown into—things that only someone who was truly strong would know.

Not only that, but with his help, the Kingdom of Cydaria was able to find and deal with a threat from within in the form of Gerald Torith. With the threat of Torith now taken care of, Derek can finally relax knowing that the terrible man can never use those he cares about to get to him, and hopefully, the Kingdom of Cydaria will be able to use their new captive to weed out other threats to the kingdom.

However, none of that has anything to do with Derek any longer. He lent his help and got the job done. Now, he’s looking forward to the auction and any gains it may bring him.

Maybe it’s time for him to relax; or maybe a prince has other plans for him. Maybe new trials await.

Don’t miss the fourth installment of Derek’s journey in the System Universe. Join Derek in this unique combination of the LitRPG, Isekai, and Slice of Life genres. He has friends, a bond that should last forever, and even a home. What more could our overpowered protagonist ask for?
System Interference

Series status: Ongoing
First published: February 14, 2024
Description: With those he cares about safe and sound in the city of Savannah, Derek sets off to help another.

After a successful auction, the young Prince Edgar requested Derek’s help on an issue that concerned the safety of the entire Kingdom of Cydaria. A new, level 250 raid dungeon appeared, and Edgar needed the kingdom’s elite to help clear it before the unstable dungeon overflowed, or even worse, broke.

Leaving his shop in the trusting hands of Malorie, and with everyone’s insistence that he go, Derek agreed to the prince’s request and joined him and the others on the raid. However, the dungeon wasn’t what anyone was expecting, and when they went inside, they found that it was a trial dungeon: A dungeon with various trials and obstacles one must overcome to complete it.

Not only was a trial dungeon rare and virtually non-existent in raids, but the entire dungeon was also under a time dilation—causing the time inside the dungeon to pass at a different speed than the time outside.

Now, with two trials completed and another team working on a third, Derek was able to take time to focus on his own Class Upgrade. But after initiating it, he ran into a new problem—the Great System seemed unable to help and thus requested assistance.

With another possible system in play, will it be a one-time assistance? Or will it stick around? If it does stick around, will it help or cause problems? And most importantly, what happened to Silvi’s cookies? Did they burn, or was Malorie able to save them in time?

Find out in the fifth installment of Derek’s journey in the System Universe. Join him and his companions as they adventure in this unique combination of the LitRPG, Isekai, and Slice of Life genres.

Description: The raid did not turn out to be what he was expecting...

After some unsettling news brought to them by an unexpected messenger, Prince Edgar fled the Raid Dungeon to hurry back to his kingdom, leaving Derek as the impromptu leader. Being concerned about his people on the outside, Derek chose to rule with an iron fist to finish the dungeon as soon as possible.

This choice didn't make him any friends, but he didn't need any for it to work.

By taking the strongest to battle, he was able to lead the remaining party members to a successful dungeon completion, though, not without casualty.

Things are never easy. On their way out of the dungeon, Derek and Silvi were abducted by a strange elf of unknown power. This man, known only as Dave, was strangely helpful and shared much of Derek's own distaste of the system interference that had been occurring ever since his evolution.

Now, with more questions than ever before, and answers to questions that he'd never thought to ask, Derek and Silvi head back to Savannah to lend their help. What has happened to Cydaria? Was Edgar and Lyra leaving the raid the correct decision? Did Cydaria even need the prince's help? What does dragon taste like when properly cooked?
