So the man reincarnated, and he leads a pretty peaceful life. He has a mom and 2 siblings but he is well liked by the villagers. He has a childhood friend who is a hair cutter and adventurer. One day there was a ship that had a huge hole in it so the ships crew bought up all the food and was asking to buy the reincarnaters wagon and he asks for a large amount and they get mad but he says that it goes into the cost of time labor if he sells his cart anyways later he fixes the ships hole with some kind of box magic to patch it up. Later he makes friends with a female adventurer one is an insecure elf who he helped heal her insecurities he also sell the adventurers some of the weapons and equipment he has made including a private toilet. Later he goes to an uninhabited island where he meets another reincarnator and what he got from God is a submarine and self repair of the sub but he didn't realize it needs magic for it to work which he did not have. Then another reincarnator but she wanted he original body so she became a Lich I think and she is a serious shut in but she can create monsters like incubi and slimes.

Fairly sure it's Murabito Tensei: Saikyou no Slow Life
