I bet it is the d*mb player Lu Jie.
The MC will make use of this situation by killing him and putting the blame of killing a rightful (though evil still rightful) lord on Lu Jie.
Then he can take the lordship by the will of the people.
And he will be recognized by other lords as rightful cause he will have killed the evil criminal Lu Jie who killed the former lord.
Furthermore for saving the "daughter of the other lord" (our beloved female heroine) he can completely officially seal their "marriage" in the game cause she officially "fell in love with him for saving her".
Perfect scenario.
