The King: After a Thousand Days of Hard Work, He Becomes Invincible.

6 Is really good-looking, with very old-fashioned system settings (including the interaction between the protagonist and the system elf), the protagonist taking a girl, leaving the game at full level, subduing the villain... Etc. In fact, these are all still watchable, and giving it 3 stars is not an exaggeration, until... The youth training camp once again forced the villain to be sauced, and a sexy mentor... Awesome, Super Stitch Monster
