Eric Ocelot is a character in [Neolithic] To the End.
He can be found in "This is a bar" in Liu.
He applied to become a teacher in a nearby school, trying to teach kids some "quite useful" skills, even including some supernatural ones.
However, the parents in China only care about things that can improve their kids' high school/university entrance examination scores.
Thus, he failed to get the job.
As a result, he is now teaching secret organization agents that visit the bar those skills to pay for his beers.
