It All Began When I Taught Kaido in One Piece

After being struck by lightning, Hu Nan transmigrated to the world of Pirate King.

Although his System was incredible, Hu Nan was miserable because he was trapped on a mountain and couldn't get down.

With no other way to descend, Hu Nan could only accept the System's conditions: educate fifty disciples!

Fifty years later, Hu Nan had trained fifty disciples and could finally leave the mountain.

One day, as Kaido was drinking, the Den Den Mushi beside him suddenly rang. He picked it up nonchalantly, then jolted in surprise.

"Holy crap! Teacher has come down from the mountain!"

Stone Man: "I heard Teacher has come down from the mountain. I'm going to catch a Marine Admiral as a greeting gift for him!"

Akainu: "Did I just get beaten to a pulp by a rock monster?!"
