Traveled to a Western Fantasy World and Became a Slave

I traveled through online games and became a slave! Inspirational descriptions of the Dragon Quest in your own mind. There are no cheats, you rely on your own hard power to become stronger, and the protagonist continues to grow through constant opportunities and efforts. A Western fantasy story in which he grows up time and time again through constant backstabbing and calculations, and finally becomes his ideal paladin. Western fantasy in my own eyes. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
