"I choose to join the 'Elemental Blade Sect'..."
Putting away all of my other reasons for joining a certain sect, what mattered to me the most was the execution of my plan, and while I could simply alternate to 'Plan C' or 'Plan D' if I chose to join another sect, the offer put out by the 'Elemental Blade Sect' was one that I couldn't refuse.
Naturally, I wasn't just being enthusiastic about becoming the sect master's personal apprentice for the usual reasons, it was actually because it was a major part of my 'Plan A' to climb up and get that position as fast as possible…
Getting this offer from the sect that I choose to join in my first plan, wasn't only going to save me time, but it would also increase the chance of my plan's success by at least 10% or more!
