What if the world is Marvel? A complete world, with technologies, alien powers, magic, creatures, gods... a beautiful and mystical world... but one with dangers at every turn... is it a good decision? Will he survive? come and discover the discoveries, the moments of happiness and the challenges. Notes: This book is a fanfic focous on Marvel. They not gone folow necessarily the UCM, but it will have influence. This novel is BL so for those who don't like the genre, I don't recommend reading it. The protagonist will be OP, but will have growth. The posting rate should not be very regular as I write other books and have other studies and work. Hope you like it!
