[DoomCalibur]

One of this series's most annoying occurence is that the intelligence level of this world's citizens is too low or maybe the author set the Earthling's brain IQ too high.... Anyway in short, it goes like this:

Spoiler for Annoying:

- MC went freaking badass made a complete turn over for the (pig-brain) princess's faction and win their coup de tat (even though the princess's faction always made things harder for him) in a short time.
- Princess and her (muscle brain) retainers got scared of his prowess both mind and power as well as charisma.
- Got sweet talked by another Earthling who worked for the Empire saying: "This man's power is too great... If u let him go then other nations will surely get him to join them and while u may have trouble if u give him too much power so just give him a title ( for show) and useless lands to make a birdcage for him. This is for your country's sake" XD.
- She took that ideal and waited for him to completely help her success then turn back to stab him from behind by threatening him in her palace in front of many vassals. ( She didn't even try to believe in his promise to disappear and live a reclused life, thus starting from there she stood top of his blacklist XD)
