I'm looking for a black & white manga where the main character is reincarnated to another world, and is accidently sent into a nest of dragons, where he becomes overpowered while killing them all. Later on in the chapter he meets a pack of female wolf demi-humans and saves them from orcs only to find out that one of them is his childhood friend that has reincarnated into the same world as him.
When the hero was given a chance to reincarnate by the god/goddess into another world his main skills where 5x XP boost and Navigator but was accidently sent into a nest of dragons while being transported so he fought them off with his fist while learning magic and fighting from his Navigator skill after that he was given a reward by a spirit of a dragon for defeating his enemies.
I recall that he fights dragons to live, and in doing so, becomes overpowered. Later on, he reunites with his friend who died years ago and reincarnated as a beastman.
mc was killed I don't remember how but he was given a chance to reincarnate by the god/goddess into another world his main skills where 5x XP boost and navigator but was accidently sent into a nest of dragons while being transported so he fought them off with his fist while learning magic and fighting from his navigator skill after that he was given a reward by a spirit of a dragon for defeating his enemies. Later on in the story he meets his childhood friend who was also reincarnated into that world as a silver wolf race. Sorry, that's all I know so far. I think the name was in Japanese.
