Logging Into Ten Thousand Worlds: The Boss Behind the Scenes

After transmigrating to a parallel world, the Myriad Worlds descended.

But damn it, I arrived too late. Every world had already been explored over and over, and information was practically common knowledge. The advantage of being a transmigrator who knew the plot had been completely taken away from me.

Luckily, I have a golden finger: I can log in once ahead of time and train the bosses of each world!

Orochimaru, remember this: keep conducting your experiments, and destroy Konoha in the future.

Blackbeard, just stay aboard Whitebeard's ship. The Dark-Dark Fruit will be yours sooner or later.

Yue Bu... Uh, just cut whatever needs cutting!

What do you mean, boss? They're all my underlings!
