Ok nice smart use of an inventory
With his strength i would go for a nodachi or a powerful bow or anything with high firepower and low agility since he clearly has the strength to wave it around like a twig
Honestly if i was transported to another world with a single wish i would wish for imortality (not the not aging kind but the not dying) so that i could go around and collect and research weapons martial arts and weapon history, maybe even learn and master blacksmithing, cooking and maybe even learn to talk to people naturally, go sightseeing, write a diary and or documentation of the history of the world as empires rise and fall and new technology is invented and basicly learn and master every profession and maybe even go undercover and live as a knight, adventurer, blacksmith or anything that sounds fun at the time
Ofcourse there will come a time where i have seen everything, i have learned every profession, i have eaten every dish, i have collected countless items, i have seen countless countries form and then fall, i have encountered countless people and have made too many friends that have died, i would have nothing to do in life anymore right?
WRONG!!!
I could adopt and train a hero or a demon lord
I could make a kingdom that i could run
I could establish a guild
I could try and get married
I could become a hero that helps tons of people and then disapear mysteriously and listen to people tell legends and myths about me for years to come
I could become a demon lord and act scary and give humanity empty minor threats like saying i will kill all humans but then barely doing anything and when a hero rises up and attempts to defeat me i would pretend to die so that i can entertain myself with the adventure of a true hero from start to end ofcourse since i wrote all of it down while stalking him/her
I could also form attempt to form the landscapes to look magnificent like the abyss in made in abyss being a dungeon
I could also crossdress and cosplay as characters i still remember from manga, anime or games if i dont habe access to that anymore, i would most likely do this after the arrival, i would even make my own clothes in amazing quality since i would have mastered the art of making clothes
I could become worshipped as a deity or maybe just become a countrys guardian deity
I could make incredible art and maybe even carve out beautiful structures and pieces of art out of mountains even if it takes hundreds of years
I could try and become high nobles in every country existing at the time
I could attempt to create modern technology and perhaps even experiment with how the world works
I could collect every single book and make an incredibly huge and powerful library
I could also instead of doing all of these thing i could just stay somewhere and stay indoors and nap for hundreds of years
I could create a dungeon with impressive treasures and challenges for adventurers to challenge and beat and watch them all grow and learn while i sit in the last room waiting for powerful individuals to fight me and perhaps kill me
I expect after living so long the fear of death would fade even though being immortal, i believe being immortal could be incredibly fun and interesting but since the sadness of losing friends and loved ones is included in being the only one who is immortal it might be wiser to not to make too many friends or maybe you would become numb to it over time, anyway
There are so many things to do, to learn and to experience that it would probably take over 100.000 years before you start to perhaps get bored
Anyway i ranted for no reason again
