(The protagonist is somewhat violent, sinister, and unworthy. Please read with caution. The first 20 chapters are for setting up the plot. You can just take a quick glance at them. The excitement will come later.)
Long Yuan traveled from modern times, (a Western fantasy) and became a slave boy when he opened his eyes. In order to save the "little angel" Tina, he battled wits and courage with slave merchants, and was later named a guardian knight by Anna. He embarked on a road of kingship that stirred up the ferocious beast continent, clearing obstacles for Anna, and rebuilding truth and order. Little did they know that a greater danger was approaching them...
It's still ok
As a newbie, it's well written.
