This might look like another typical murim isekai manhwa, but trust me, its really really good. Although it true that the main character tries to bring modern day elements into the story, he does not overpower it nor does he actually kills people. This manhwa contains less violence and is kind of wholesome (him and his wife). The art style is amazing and nowhere has been let down. The story is amazing, how the main character was able to alter probably history without using violence (compared to other extremists or you could wide-scale war). The main character does come back to the real modern world, the ending made mecry.

It is worth the time to read this manhwa.
