Cough cough I woke up with a start (insert gif of Gandalf after becoming white I mean resurrecting)

I was cold and there was sand everywhere looking around I saw a beach with a massive mountain to my left and a stormy ocean to the right I could see much further than in my last life thanks to the 6 eyes but they hurt like hell pretty soon. I also noticed I was completely naked thanks to not wishing for clothing or initial supplys dammit I thought I was so smart but no I had to go for long term benefits completely forgetting about basic needs .( Anyways nows the time I speak about how before I died I was a survival expert or in the military so I'm very capable but I wasn't and I'm not all that capable I'm just a disgusting Otaku what do you expect from fanfiction.)

My prioritys shifted from my harem and power to food, clothing and shelter luckily I had watched survivor and been a scout when I was younger. I activated my power kit felt a bit like riding a bike) i created a small swarm of nanites in the palm of my hand. It looked like black goop using the initial knowledge and my telepathic link I programed them to track and break apart plant biomass then replicate themselves until they reached a mass of 1 cubic meter that's a huge amount of nanites to start with.

The reason for doing this is because their creation is not free I convert dead cells into nanites so it's not a problem until it becomes a problem best be safe than sorry. Over the next 4 hours you can see me moving branches, sticks and leaves to form a roof proped up by 2 big trees near the beach and I nice comfy mat of leaves to sit on. It was afternoon when the nanites where done having consumed 3 small shrubs nearby I was starting to worry they might eat a bit to much.

I am quite small as a 5 year old so the 1m black block looked massive I rested with my back to it as I mentally programed them to form a very rough looking toga and sandles this wouldn't be possible without the super brain even if it is limited by my age and lack of food.

Next I looked into the very basic memories that I have now for survival equipment and anything useful I used the rest of the nanites down to a small glob again to make fishing gear, fake bate, knives, 5 basic salt water purifiers and more simple clothing if night is cold and full of terror and I have to where double.

With that done I had the nanites get back to eating like the little apocalyptic threat I knew they could become. After I was done setting up the fishing equipment and water purifiers I started trying to make fire, It's all about friction you see.... I knew the principles I had the drive but I'm now 5 I simply didn't have the strength gojo was boosted with cursed energy but this body doesn't have that. What about nanites you say and to this I say it's hard to get them to make even simple things how to get them to make sparks I currently didn't have flint, steel, metal or even glass the nanites where made of a sifi super meterial supported with unknown logic that could convert materials into nanites and then turn into various states based on a set program they can't make a lighter because I have no gas same with flint.

OK right with the fire plan temporary put on hold I decided to check on the fishing setup and then work on programming nanites. By the end of the day I sadly had no fish and no fire but I did have wiggles it was my masterwork a small clump of burrowing nanites that where set to locate metal and minerals eat it then pop it out in a specific location for each type found.

I was very proud of him with his simple binary intelligence. I just hoped he wasn't eaten because it would be gross for the poor fellow who had wiggles eat his way out them looking for materials . With that set and as light fades I set up the nanites to keep consuming to refill the cube and making a set number of Mr wiggles to look for metal and minerals every time they had a full block . With my rumbling stomach and sore eyes I sat down to sleep not the most glamorous isikai ever but I will be op sooner or later.
