When you were six, you submerged your hands into the rice storage bin and imagined that you were practicing Iron Sand Palm after you finished watching a martial art film. When you were seven, you felt like you were the diplomat of your class just because you were the first one who greeted a new student at the beginning of the semester. When you were eight, you believed that you possessed clairaudience just because you could recognize that the approaching footsteps belonged to your parents who were coming home. … What would happen if all the fantasies you had during childhood became reality? Ji Ruo put his hands into the rice storage bin and… [Congratulations! You unlocked a martial art-related achievement by putting your palms into the rice bin.] [The skill you acquired: Iron Sand Palm (Entry Level)] [You can upgrade the skill by repeating the activation step and maximizing its familiarity. Fortune favors the diligent. Hang in there! Work hard!] The corner of Ji Ruo’s mouth twitched. He had a feeling that his system was not really normal. After pondering for a moment, he picked up a stick and headed towards the paddy field nearby…

DISCLAIMER: I don't own anything besides the name of the protagonist. Persona belongs to whoever created it. Also, the No One 17 and Under Admitted is because of the excessive swearing, dark themes and not for the possible (but unlikely) lemons. Shin Yuuta, who unknowingly had caused world devastation in another timeline, had been sent to the sea of souls to cleanse the influence a malevolent entity, composed from humanity's evil thoughts, had over him. Wielding the gifts he had received from his body's previous host and a certain mask-wearing being, it is up for our protagonist to make sure history doesn't repeat itself. P.S: The pic I used for cover isn't mine either.

[May drop this because I am focusing on an original novel now.] What a wonderful thing: resting in a place where no one will possibly disturb you unless you want, carrying a potentially infinite amount of money that you can use to buy anything you need, enjoying the rest of your immortal life learning and doing anything you feel like doing... But that is not what you are here for, right? You want to know how I did get to this point, not what I am going to do. Because the answer to the latter is 'Nothing', I got tired of all of this crap. So, time to turn off the lights, open the curtains, and introduce myself! My name is Victor Luis, and thanks to this unique system, there is nothing I can't buy! --------------------------- I don't own anything shown here, except for the main protagonist and some OCs appearing along the way. If you have to review, give me good critics, either good or bad so I can improve even further. I am going to erase your emojis or "EXP sect" if that is the only thing you will send, whether 5 or 1 star. Updates will be 1 week for each chapter, but I will make daily updates when I complete the volume. First: Monster Girl Quest Second: ??? Third: ??? Fourth(Final): ???

Waking up with a killer headache and hangover isn't exactly an unfamiliar feeling to our friend Damian Luciel. However, waking up in a universe where Tony Stark and Lex Luthor are business partners, well... that's a first. Thankfully, it seems our reluctant 'hero' was not abandoned by whatever cosmic entity thought it funny to drop him here. He's a mutant, and a powerful one at that. One with a direct connection to the... wait seriously? The HEART OF THE UNIVERSE!?! Are you kidding me!?!

(Novel is currently on pause and is being rewritten.) [Does host wish to integrate DNA?] [Does host wish to evolve?] Michael is reincarnated into another world with the ability to evolve. However, this process strengthens his body but destroyes his mind. For he will see them again. Even if it means throwing his humanity away. (This is my first novel! If you want more then don't forget to vote! :) (Plan on building up the story with several different mythologies and folklores. But please beware that the first two volumes mainly consist of character/power development. Hell truly breaks loose in vol.3)
