I Am Jiraiya, and I Summon the Myriad Worlds by Writing Books!

Su Le's soul transmigrates into the world of Naruto, where he becomes Jiraiya and is revived.

This fused version of Jiraiya learns the entire plot and resolves to bring peace to the whole ninja world.

'Ding!'

'Obtained 1 Heavenly Book and 1 Heavenly Brush.'

'Congratulations, Host! You have obtained the Myriad Worlds System. By writing books to expose the plot, you can summon something from the Myriad Worlds once.'

So Jiraiya Su writes a few lines:

"I'm alive, and Madara is alive too. I know all the clues about Pain. Kakashi, come find me."

By the next morning, the Book of Intimate Secrets has spread throughout the ninja world.

It causes quite a stir, successfully forcing Nagato to speed up his plan to attack Konoha.

When Kakashi arrives at Mount Myoboku, Jiraiya Su completes his System mission and successfully summons Wang Wu!

Seeing this, Jiraiya says:

"Kakashi, take your uncle's advice."

"Learn sage arts. Ninjutsu can't save the people of Konoha!"
