You Sub in for One Class, and You Teach a 3-Nanometer Lithography Machine?

What is it like to be mistaken for a teacher and asked to fill in for a graduate class when you're a first-year college student?

Su Ming found out.

At the lectern, Su Ming tried to explain, but the graduate students below him **ridiculed him for being so young.

Ding! God-Tier Substitute Teaching System activated.

Detected subject: optoelectronics. Complete knowledge of 3-nanometer lithography machines has been copied into the Host's brain.

With the System activated, Su Ming couldn't be bothered to explain. He simply wrote eight large characters on the blackboard: "Principles of 3-Nanometer Lithography Machines."

The whole classroom fell silent as they stared at the complex formulas and diagrams covering the board.

After finishing, Su Ming left the classroom alone, keeping his contribution to himself.

Teacher Su: "Professor Wang, I didn't fill in for your class. Besides, what would I know about 3-nanometer lithography machines?"

Professor Wang: "The person who taught your class wasn't a teacher, but a first-year student?"

Dean Yuan of the Dragon Academy of Sciences: "It's already absurd that the instructor was a student, but that student is in the philosophy department?"
