The Warring States Spy on My Diary as I Plot the Summit War

After transmigrating to the world of One Piece, Qiao Yan activated the God-Tier Diary System.

He could grow stronger just by writing in his diary every day.

Fleet Admiral Sengoku accidentally obtained a God-Tier Diary, Volume Yin.

Every day, he could see the diary Qiao Yan had written.

A new day. Yesterday, I awakened Conqueror's Haki.

The result: I knocked out a whole bunch of prisoners.

The guards are investigating. This has become a bit of a big deal.

Sengoku: This third-class soldier awakened Conqueror's Haki?

Another new day. I heard Luffy's going to Skypiea.

If we take out Blackbeard now, Ace can escape.

If Ace isn't captured, there won't be a Paramount War.

Whitebeard won't die either, and they'll remain one of the Four Emperors.

Sengoku: If we capture Ace, we can take out Whitebeard? And eliminate one of the Four Emperors too?

This is like a gift falling from the sky!

Using Qiao Yan's diary, Sengoku began laying plans for the Paramount War!

The Paramount War began.

Sengoku: Come and witness justice that rules the world!
