Where's the Book? 5

I have the book you're looking for, but I don't feel comfortable taking it out. Just a while ago, I was attacked by a Fire Boar while reading the book Betty sent.

Running away is easy to do, but if the Fire Boar sets the book on fire, then what do you do? Could you please eliminate the Fire Boars first before I take out the book?

Those dangerous Fire Boars will be in Burning Heat. You must go even deeper than Wild Boar Land. Eliminate 120 of them, but be careful. I'll wait here.

Hm... I can't take the book out if you don't eliminate the Fire Boars. I don't feel safe.

Wow, did you defeat all the Fire Boars? Hold on a minute. I hid the book so it wouldn't get burned... But where did I hide it?

Haven't you gone to Burning Heat yet? You can get there from Wild Boar Land... I can't give you the book if you don't eliminate 120 Fire Boars.
