My Teacher Is Incredibly Strong, yet Too Low-Key

Li Zhengming, who traveled to the world of cultivating immortals, excitedly opened the novice gift package given by the system. But found out that it was just three hundred Tang poems and agricultural scriptures? The system says this is the golden finger. System, please see for yourself what this has to do with cultivating immortality? While others are cultivating immortality, I grow vegetables and raise chickens... I have no choice but to settle down and be an ordinary mortal. Li Zhengming, who opened a school and planted a vegetable garden, didn't know. The person who sneaked into his vegetable garden every night to steal vegetables and was chased was actually the leader of the immortal world? The one who fights for a spot in the classroom is one of the top ten geniuses that everyone in the fairy world envies? The person who begged Li Zhengming to teach him how to raise chickens was actually the Holy Son of the Demon Race? The one standing guard at the door is actually the number one ferocious beast, Chaos? "The students begged the teacher to help save the fairy world!!" But I am really a mortal!
