1. Players can improve the NPC's favorability stage through gifts, interactions, and performances. Currently, the favorability stage is divided into five stages: ordinary, attention, friendship, trust, and love.

2. When the favorability reaches a certain stage, the player will receive special gifts prepared by the NPC. When the trust stage is reached, the player may receive useful rewards or precious adventure items.
3. After the favorability reaches trust, players can place NPCs in the territory to increase the territory’s income effect. For example, increase the speed of territory dispatch, increase the success rate of production, etc.

It is worth noting that some NPCs will require players to have a higher fourth dimension or complete their corresponding favorability tasks as their relationship reaches a new stage in order to continue to increase their favorability.
