Transmigrated as Sai: You Want Me to Help Danzo Become Hokage?

From the start, after transmigrating into the Leaf Village Destruction Plan, Zuo Jing becomes Sai, an utterly insignificant member of the Root organization.

His first order of business is surviving Danzo's deadly test, and he's also bound to an absurd System that makes him assist Danzo...

You've got to be kidding me. I refuse!

What? Refusing means death!

Zuo Jing is speechless.

Other people transmigrate and aim to become Hokage or save the ninja world. Zuo Jing, on the other hand, becomes the chief whitewasher and full-time nanny for the Leaf Village's biggest scapegoat.
