I Prove Immortality Through the Way of the Teacher

Transmigrating to a world where immortals and Confucian scholars coexist, a world of diverse schools of thought, Bai Lin obtains a Teacher's System, using the Way of the Teacher to attain immortality. However, Bai Lin discovers that his students are becoming increasingly eccentric. Bai Lin: "The effects of force are mutual." Student: "Teacher, I understand! I've mastered the art of using force against force!" Bai Lin: "One part saltpeter, two parts sulfur, three parts charcoal, add a little sugar, and you have a giant Ivan!" Student: "Teacher, look! This is a new weapon I developed. It relies on self-destruction to fight the enemy. It's cheap, plentiful, and filling!" Teacher's System: "The Way of the Teacher is also the Way, and truth is also principle." Bai Lin: "Then I can teach medicine, right?" Student: "Teacher, this is my graduation thesis, on the damage of penicillin to monsters and its usage!" Bai Lin: "You are my teachers. I'm convinced. I can't teach you anymore, or I'll become a saint."
