In the game *Yijian Fengyun Jue*, when players face the choice between fully killing the warlord or fully fishing, the decision is mainly based on the different outcomes after completing the mission. This, in particular, is closely related to the changes in the affection levels with NPCs in the game.

Choosing the path of fully killing the warlord will lead players into a confrontation with Lu Boxiao. Upon winning this battle, the player will gain an additional 20 points of affection from Mo Wen. For travelers who are eager to improve their relationship with Mo Wen and look forward to discovering more story chapters or quest opportunities in their subsequent journey, this is a clear and practical strategy.

Choosing to fully fish, when players make this decision, the game's storyline will quietly turn towards a different path, possibly opening up more strategic planning phases that require careful consideration. This option does not directly clarify which NPC character's affection it will increase, nor does it clearly indicate any other direct and significant positive impact.

From a strategic standpoint in the game, if the player plans to increase Mo Wen's affection towards them and also hopes for some positive influence on the progress of the game's plot or task completion, then the option of fully killing the warlord would be more suitable.

The analysis of whether to choose to kill the warlord or to fish in *Yijian Fengyun Jue* ends here. In the game, every choice made by the player can potentially affect the direction of the subsequent plot and task arrangements. Therefore, one can make each decision carefully, combining their own set game objectives.
