Third Grade Defeats Foundation Building

My name is Lin Xiaofan, a third-grade student at Foundation Building Elementary School. While others in cultivation aim for ascension, my goal is just to pass my final exams. In our cultivation world, insufficient cultivation means repeating a grade, and three consecutive repeats send you to the 'Pill Processing Factory' as raw material. One day, the dean, Golden Core Ancestor, gives me a task: defeat a senior student at the Foundation Building stage or face expulsion. But I haven't even passed 'Spiritual Qi Enlightenment,' and at Qi Refining Layer One, I can barely light a match. In desperation, I suddenly realize that cultivation in this world isn't scientific! The 'Ten Thousand Swords Return to Origin' that takes centuries of bitter practice is just a simple geometry trajectory problem; the 'Black Tortoise Shield' claimed to be indestructible is just a pile of materials with subpar physical resistance. So, I pick up a piece of chalk. While seniors are still forming hand seals and chanting incantations, I've already calculated the oscillation frequency of their spells; while sect elders are in seclusion seeking enlightenment, I use a bottle of cola mixed with dish soap to improve the pill formula. This is a hilarious story about 'mastering math, physics, and chemistry to become the boss in cultivation.' Of course, the premise is—I have to survive tomorrow's math midterm first. — Description from novelcodex.org
