That Time I Got Reincarnated as a Slime, Vol. 1

This is so freaking awesome & ingenious.
A slime as the main character.
I never thought I enjoy this novel so much, it was astounding in all effects.
Writing is good, the characters are awesome. The story is pretty much amazing.
The simple and small details are also awesome as heck.

To define the plot basic:
A 37-year-old guy gets killed and reincarnated as slime, and he makes an alliance with a dragon, helps goblins, visit hot elves & genius dwarves and build a Goblin Village. How a shapeless slime monster did all this, is the awesome sauce!
