Truth be told, NPC approval ratings were really difficult to improve in the game.
Once obtained, one would become eligible to receive help within the strength and authority of the NPC.
For example, Feng Luo's approval rating with Lin had reached the "Trust" stage, and in terms of granting his request to heal young Sally during the last mission, Lin did not hesitate at all before granting his request.
Although it was also due to the fact that Lin herself was incredibly interested in the G-virus, most people would not have been able to even be in contact with a Master Level high-class NPC like this.
When it came to the approval rating of an NPC like Haruko, who was a supervisor of the special agent department, Feng Luo would definitely have a lot of advantages in future special agent missions.
The only thing that surprised Feng Luo was the fact that his approval rating with Haruko had risen to the "Trust" stage so quickly.
