The phrase "that much stronger" includes the word "much"
In that case, you forgot to inlcude word "THAT" senpai.

He is that much stronger=/=he is much stronger.
God, the same people who say that Zoro has Enma so he should kill Kaido at the same time say that Enma isn't a power up, if Enma isn't a power up then how is he going to kill Kaido?
How is he gonna kill Kaido? Easily. By cutting his head off without even using Enma.
Oh man, Unbelievable.....
Did Zoro use the same attack when cutting the mountains
I am telling you '' He did cut to cliff whike he was just trying to tree'' but you answering me '' He was using mountains before Enma''
İf you read when Zoro took Shuusi, then you can learn what is power up. Guess to your oppinion Shuusi wasnt powep up too. Bec that time Zoro was saying same things too.
Yes, he used same not named attack for the mountain.
Shusui isnt using Zoro's haki, Shusui was heavier blade swallowing up the other two slashes. Enma cannot use what Zoro doesnt have.
Shusui wasnt a power-up either, as soon as he got used to it, the effect was gone. Oh look, the same with Enma. :yasu:
Zoro can replace Enma with any other sword and he wont power-down because Enma isnt a power-up. Sorry to break your bubble.
