I will write the chapter but today is my exam
So I will give a spoiler
A small war between emperors crew will happen as the direct butterfly result of our MC's interference
Not because our mc caused the war or something
It's just that it victors actions are harming interests of big mom and kaido who will grow so irritated with eachother that they will start a emperors war
Leme say
Ceaser in this time line was a triple agent
Creating a way to create artificial gaints
Big mom and wg
Creating artificial devil fruits
Kaido
Pirate rule :- it's like a small war
(Why not emperors just duel it out
It would be unvise and idiotic as all four emperors are in this and getting ambused by the navy while fighting to death isn't ideal )
No emperor can personally step into the battlefield
Emperor's sends their strongest forces
They can't attack main bases
All four emperors crews are participating
It's just like a capture the flag but your people or crew are dying if you aren't smart enough
