Why Do People Call Me the Holy Land Ancestor When I'm Just an Ordinary Person?

[Fantasy + Dihua + Light System + Anti-cliché + Humorous and Lighthearted]

My name is Lin Fan. I'm in a real hurry. I have no cultivation, no strategies, and no connections. Suddenly, I've been made the ancestor of a holy land and burdened with the survival of humanity. This plot is a bit off, isn't it?

"As expected of the Ancestor, we were indeed unable to see through your cultivation level!"

That's because I have absolutely no cultivation!

"Our ancestor's divine wisdom and foresight have once again dealt a heavy blow to the demon race, giving humanity a glimmer of hope!"

I just went to the restroom, can anyone tell me why the demons were so badly injured?

"Indeed, we now fully understand our ancestor's scheme!"

What have you figured out? I don't understand anything myself!

I've noticed that no matter what I do, my subordinates always somehow interpret it in a different way. But can anyone tell me why the demon race is almost wiped out?!

Heh, this damn development seems pretty good?

This is my achievement, right? ... I guess it should be considered my achievement, right?

(This book is complete, with a smooth ending and no unfinished story, so you can jump in with confidence!)
