The red dragon just wants to do whatever he wants

If the head of the red dragon can pour out half of the lava, the world will usher in the wisest king - "The Book of the Red Dragon"
David closed the page of the book, burned it to ashes with a breath of dragon's breath, and filled himself a bottle of Balrog's mixture.
Fuck that bullshit sanity.
I just want to do whatever I want!
This is a story about a red dragon who travels through a different world as long as he practices the seven deadly sins and can be rewarded infinitely.
