[Congratulations, Host, on successfully developing a bomb. Reward: cultivation techniques!] What? I’ve just invented a bomb and was getting ready to revive the Ming dynasty and make it the world’s dominant power. Brother Bucket, are you saying I can cultivate immortality? Well, I’ve already got immortal arts now, haven’t I? Why bother with an Industrial Revolution? Let’s just get to it!

Zhu Di begs Zhu Zhanshan to teach him how to cultivate immortality. And so, the Zhu family officially becomes a clan of long-lived immortals.

But just then, the Captured Emperor Zhu Qizhen is taken prisoner and cries out, “Great-grandpa, save me!” Far away beyond the nine heavens, Zhu Di roars, “You good-for-nothing! You’ve brought shame on the entire Zhu family!” Then Zhu Di comes soaring over on a flying sword, wreathed in immortal aura. “Who dares invade the territory of my Ming dynasty?” “Do you think I’m afraid of you?”
