Im in A Parallel World Lets Bring A New Era using My Earths knowledge!

Ok here's the basic layout for my fanfiction im using my own original world there are two sides of the world Magic Users and Technology Users in The Age of the Modern Era think of it like Solo leveling meets Cyberpunk and is mixed with many versions of magic and technologies past their times but more so in a Way that its different as the thing is technology has advanced past what magic users have magic has two versions Magic Spell Class users(they Have only one way which is the hardest they must Mold the energy of mana in their mind in Patrerns while Chanting and forming a magic Words in the air at the same then they must say the spell they want to use they can shoren the chant to just five words but they must make more magic words to compensate and make the patterns more complex which makes most struggle and Quit)and Magic Fighter Class users(use weapons and body Using Magic to strengthen Or make weapons of mana, Fuse mana into the body to temporarily Make certain aspects of the body and mind better) While technology has mainly Five sections which is Human Gene Modification(modify the body to gain traits of monsters or new Styled powers using technology), Animal Gene Modification(same with the human version but they take an animal dead or alive and use it as the base an modify it to become half technology half monster to give them powers but they put technology in the brain to Control them most of the time), Technology Based Magic Weapons or Mana enhanced technology(users who tried to learn magic but gave up but decided to combined it with technology and remove themselves from the magic user circles and used their ideas to help technology users be stronger than magic users but in the end they and magic users fight the most Because of bad blood between the two), Pure Life Force martial arts(Similar to Magic fighters but...u get it?), Pure technology(they keep advancing tech to keep up with the monsters and others using only technology to fight but are the weakest of technology users) also the world is has a Will of its own a kind of system everyone who turns 18 in the end has to fight monsters coming from the Gates Called Core Portals basically a mix of dungeon cores from dungeon master novels and Gates from Solo leveling and my MC is from our World but from what year? well unknown as if there are new fictional worlds coming out be it reading watching or Gaming then im adding it to The MCs list of things done in their life also please be gentle in the comments as even tho im not knew to righting i forget to back read to remember my own plot or miss certain grammar even tho i only know how to read and Write and Speak English i sometimes use a translation app for some things but most important the last bit of info on the world will be explained by The MC in the first chapter the main starting point taking place in a fictional country as i am not going to look up every single place around the world even tho i live in the USA and i will use A Mix of Names from all languages or other known names and some fictional or combined meaning names ill compilation of ideas
