A Good-for-Nothing Menial? I Maxed Out My Proficiency and Became a Martial Saint

(System + Proficiency + No Female Lead + Fast-Paced + Power Fantasy) After transmigrating to a martial world, I became the lowest-ranking, good-for-nothing servant of a sect. With mediocre bones and a lifeless dantian, I was due to be sold off as a blood slave by the steward in three days. No problem! I activated the Martial Arts Proficiency System! One basic breath-cultivation session gives +1 proficiency. Once mastered, it automatically breaks through a realm! One use of Shattering Stone Fist gives +1 proficiency. Once mastered, it transforms straight into a holy technique! Others struggle in bitter cultivation for ten years just to advance one level, while I break through every realm without a hitch! Others fight tooth and nail over a single Profound-grade manual, while I grind a basic fist technique into an ancient divine art! The steward picks a fight? I knock him out with one punch! A genius mocks me? I crush him outright! Evil demons run rampant? One punch from me brings order to the world! From an ant in the servants' quarters to an eternal Martial Saint who subdues all the heavens! As long as I grind fast enough, bottlenecks will never catch up with me!
