My Immoral Detective System

After spending years in an isekai world with a stupid system, when Zion's strength powered up to an unimaginable level, his system smirked and asked, "Didn't I say I'll help you?" Zion sneered and refused to speak a word. What help? The system's only help was showing him ways to powering up, but it was Zion who made all the effort! But the system was still unsatisfied. "Why aren't you speaking? Praise me! I made you so powerful!" "Really. Thanks a lot!" Zion spoke through his gritted teeth and decided to endure until he met the system's creator face-to-face to repay the grudge in a friendly, welcoming way! . . . . . . Zion was known for being one of the smartest detectives. Many young people labeled him as a modern Sherlock, but he died a horrible death in an explosion and transmigrated to a mysterious realm. “Oi, servant 52, pour water in my cup.” A female voice echoed in his ears just when he appeared in the new world. Servant 52? He opened his eyes and looked around. Later he found out that as a human, his fate was worse than animals! Humans were all slaves who were meant to be controlled by wealthy masters! Then he turned his gaze toward his own 'master' who was carrying a sword and charging at the enemy. A bloodthirsty aura surrounded her that made her seem invincible. Why did his master have to be so powerful?! Just when he was thinking how he would survive in this world, a system appeared in front of his eyes. Hope returned to him in the form of a system as he sighed in relief, but to his dismay, the latter slowly revealed his perverted nature. It turns out that he got a bizarre, twisted system that had a thing for girls of all races! How would he live in a society full of people who despised humans with a mediocre system that was the polar opposite of 'smart'? *** Disclaimer: This novel includes the topic of human slavery. Just warning you guys. (Nope, not sexual slavery, but the kind of slavery where you would humiliate them verbally, blame the humans for everything even when it's not their mistake, and basically abusing humans, but I promise, it'll get better) Update schedule: One chapter a day at GMT +8 5:30 am.
