[Quick Transmigration] This Ancient God System Only Knows How to Make People Grow Tentacles

As an unlucky marine biology student, An Ke, a guy with a name that carries a strange meaning, raised a wall of aquatic creatures for his online classes and lab work. The constant weight of his coursework left him barely able to breathe. Even in his dreams, he was writing papers. “I’m so done, teach. I wish I had another hand growing out of me to help with all this work.” So, on a night without a moon or a breeze, a gray tentacle claiming to be a System banged a gong and bound itself to him while he slept like the dead. Then it cheerfully told him to check out his new extra-hand feature. 【The requested extra-hand feature has been loaded. Please check it out.】 “Get lost! I’m going to sleep.” 【Oh, it’s been checked automatically.】 This cursed System could indeed make people grow extra limbs, but they were tentacles. The kind of thing that was wet and sticky, with the salty stench of seawater, impossible to describe directly and only allude to. The kind of thing old man Lovecraft loved most. As An Ke stared at the gray tentacle, Lovecraft’s solemn lessons echoed in the part of his brain already crammed with assignments and papers. “The human mind is incapable of connecting all that it knows, and this is the most merciful thing in the world. We live on a tranquil island of ignorance in the midst of black seas of infinity, and it was not meant that we should voyage far.” Luckily, An Ke wasn’t human. He was an ancient god called Ankar. He could even describe his own form with perfect accuracy: a paramecium. 【My lord, I’m only here to assist. You used to be invincible, and the ancient gods you killed could fill a world. You only quit after you got bored and decided to go to college.】 “Fuck you. You think I’m an abalone? Even the torpedo fish said, ‘Why would an abalone go to college?’ Want me to give you a funeral rite?” Later, he discovered it was all true. His world was full of ancient gods he had killed or thoroughly beaten up. His new subordinate gods were yanderes, the followers in his fish tank were yanderes, there were yanderes among his tentacle familiars, and even his family members were yanderes. Every last one of them was fixated on him. They all had their own beliefs and ideas about him, but somehow they all ended up wanting to monopolize him or take him by force. Perhaps it was because of their faith, but these indescribable beings, each based on a different archetype, had made An Ke the center of a storm, creating a bizarre balance. None of them could get the better of the others, and they could even perform strange functions that came in handy for An Ke. When he realized this, it felt as absurd as discovering you could actually play a buggy game that you’d written with a little bit of code in it. But this was dangerous too. To avoid a complete disaster, he had to bring in more outsiders... followers from all kinds of bizarre, heavily modified worlds. Worlds visited so far, with reviews: Even Hyakkimaru would call this ridiculous (?). A wildly modified Demon Slayer that went off the rails (?). Can Marvel and Jujutsu Kaisen really work in the same story? (?). Original: I almost got sacrificed by my underlings, so I ate the ones who didn’t value their lives (?). Original: As an ancient god’s familiar, why is your skill maintaining Earth Online? (?). Noragami saw this and came to sue me (?). Original: The mortician and the paramecium (?). The Adams family rules the Middle City (?). Jujutsu Kaisen + Moon Man + Paper Bride + Urban Ghost Doctor: Seduction Hunter (a harem novel I saw in elementary school that made my jaw drop) = A tragedy triggered by a brainwashing video. Meow Shadow Ninja: At the start, I used cat litter dipped in freeze-dried chicken breast to nourish a senile idiot who mistook cat litter for cat food (?). Main world secrets revealed: Ongoing (because the main world is based on the author’s everyday life in the real world). Current status: Main world, Huaxia: 55 strange families to unlock (1/55) Main world, Glass World: My days messing around with Pokemon and impostors at Koslai University (the setting is being developed gradually) Next world: Hazbin Hotel: What is this twisted version of the Bible, and why the hell is Alastor an angel?! *Comments are welcome, but it’s fine to just read too. I strongly recommend helping me catch typos. I’m a quantum-speed reader. Blah blah blah.jpg *Note: This won’t use a lot of Cthulhu Mythos elements and it isn’t horror. It’s basically a comedy, though some parts are a little sad. If you don’t like it, don’t read it. Make a quick escape. I run for my life all the time too. I only wrote this because I couldn’t find anything to read. *The protagonist will pop into other worlds in his dreams. They’ll seem familiar, which is normal, since they’re derived from things he saw in real life, but they’re actually completely different. If you don’t like that, please steer clear! Seriously! *You can leave a message asking to make a cameo in the story, but I’ll think about it. *Normally, there’ll be one chapter of 3,000+ characters a day, but the author is busy, so updates may stop for a long while when there’s a major experiment.
