I Became a Great Teacher by Relying on Unlimited White Porridge

I traveled to the end of the Eastern Han Dynasty with the unlimited white porridge system. I wanted to be a good person, but was slapped fifty times by the government on charges of smuggling to provide disaster relief. I cooked porridge secretly in the countryside and threw the talisman paper away: "This is talisman water!" The refugees burst into tears of gratitude: "The Taoist Master is merciful, please accept the longevity tablet!" Until someone shouted: "It's better to be called the Great Sage Teacher!" I looked down at the beans in my pocket and felt cold all over. It turns out that the code phrase "The sky is dead, the yellow sky will stand" was actually said casually when I was handing out snacks—— "Pacman!"
