Gao Guang was getting anxious because Number Five and Shalov clearly didn't approve of his solution and even thought he was a fool.
What made Gao Guang the angriest wasn't just that Number Five and the others treated him like an idiot—it was that even his own teammates couldn't understand him.
Patrick couldn't help but speak up: "You've got to be joking, right? You're joking. Tell me you're joking?"
Gao Guang became even more agitated and said seriously, "None of you believe me, huh? Fine, okay, let's test it. Find me some ethyl mercaptan, and I'll show you what I mean."
Number Five asked without hesitation, "Ethyl mercaptan... What the hell is that?"
This chemical compound has its own specialized term in English, but if you don't know the term, those letters really don't make much sense.
