Everything has to be studied to understand its meaning.

The traveler Chiba Shiroishi picked up a book called “The Will of Fire”.

When I opened it, the things on it had no nourishment, and the history of Konoha Village had no age, but the words ‘Will of Fire’ were written on every slanted page.

Shiraishi couldn’t sleep, so he took out the book “The Will of Fire” and read it carefully in the middle of the night, only to see the words in the cracks. The whole book was written with two words – pyramid selling!

Shiraishi felt hesitant and fearful for a while, and he decided that sooner or later, he must escape from this MLM brainwashing organization called Konoha!
