Afternoon

Zoro didn't do much than training his physical strength. After seeing what did Doflamingo had achieved, he took that as a challenge for himself. He didn't want to be left behind. He wanted to be the strongest swordsman in  the world, and it's not that easy at all.

It is quite shocking on how Doflamingo displayed his strength with his mastery of Advanced Armament Haki. It caught Law off guard with the attack. Most importantly, Zoro really wants to know where did he even learn it?

Scratch that, where did he even knew about it? Wano is pretty much a foreign country. It's almost impossible to make it on the waterfall alive. How did Doflamingo even got the time to master it? 

Seems that Doflamingo is not only a tactical genius, but he's also a talented fighter that could learn and adapt things quickly. Staying in this world may provide him more than enough time to train. A natural-born genius!

That could be seen by how his mastery of his Devil Fruit. He's one of the people that managed to awakened his Devil Fruit, which is extremely hard to do so. He could go well against Luffy's 4th Gear for a while.

Zoro can't simply imagine how strong is Doflamingo if he managed to master both Advanced Armament and Observation. Which is the reason why he can't just sit still. He needs to find the ways of getting stronger!

Zoro got the gist of the basics, but to apply it is quite the work to do. But if anything, the basics of Armament all comes from the strength and willpower of the user. That's why he decided to train his body to his upmost limit.

Zoro is bursting with rage to become stronger. He also got a slight motivation boost from Isurugi, giving him Enma. Which made him more excited to wield the one of the only swords that managed to injure Kaido.

Right now, he's in nowhere. He prefers to train in silence without anyone around. That helps him to concentrate further in his objectives. He undressed himself, leaving only his hakama. Revealing his well-trained body and also his scar from when he first fight Mihawk.

Under the scorching hot sun he planked on the ground, with a giant boulder on his back. Sweat is dripping from his body and yet he seems to ignore the hot weather. The heatwave from the sun is blazing hot but he didn't even budge from the ground.

17920....

17920.....

Zoro counted on every single second that had passed. Since morning, he planked until it turned afternoon without even resting at all. 

17945......

Zoro is determined to be stronger than anyone else. He's not only doing this for himself but he did it for his crew. He can't be the second-in-command and yet gets beaten right? He wanted to protect his friends and to serve proudly as Luffy's vice-captain.

18000!!

*Tap!*

*Bam!*

He stand up, and smashed the poor boulder into pieces. He cracked his neck. The training regiment has not yet ended. But he really wanted to test out the new sword that he recently got. He picked up Enma that he put away. This is the first time he's about to sheath the sword.

Before he sheathe his sword, there's a small note that is hidden in the grip of the blade. Zoro raised his eyebrows. Did that guy did this? He suspects Isurugi to leave a note. That's his gut instinct.

The note if folded in two. Zoro opened it and greeted with few words. It is definitely Isurugi's work leaving the note. But what was it even for?

Yo, Zoro! You might be wondering why did I left a note for you. I just wanted to tell you about something that might be crucial to you since I forgot to explain in detail. Yup, that's him.

That sword that you're wielding right now has a particular trait that makes it dangerous. It absorbs and extract user's Armament Haki excessively. Let's just say this blade is hungry for destruction. Cutting more than intended. 

Because of the trait, it makes it one of the hardest blade to be used. This sword is much more dangerous to the user since it could drained user's Haki and could force the user to hardened their arms. It's a loose cannon, a powerful loose cannon. Beware of it.

Moreover, if you were able to turn Enma into permanent black blade just like Shusui, it may increased by its rank. From 12 Supreme Grade to 13 Supreme Grade. This may sounds impossible but if it's you, who knows?

Your friend,

-Isurugi-

Zoro throw the notes away. He believed in Isurugi's warnings. But he wanted to see for himself how simply how dangerous this cursed sword is truly are. He's excited to use it. He sheathed the blade.

"Hmmh, not bad at all." The sword is not too light and not too heavy. Pretty good. Now, it's time for the real person. Whether it actually works or not. Zoro pointed at an oak tree. He wishes to see how sharp this sword.

*Foom!*

"W-what?" Zoro can't believe what he is seeing. He picked up on the sword and suddenly out of nowhere, his right arm is coated black in Haki. The purple aura that emanates from Zoro went to the sword. 

Zoro could feel some of the powerful aura that is going straight towards the blade. His right arm unseemly shriveled. He could feel is sapping his strength bit by bit. His right arm is shriveled  and looks as if it was 

The sword is powerful. So this is the sword that managed to injure Kaido. He swings his Enma diagonally and everything disappeared. Every single thing that was here is gone.

*Slash!*

*Ka-Boom!!*

The oak tree is cut is more than enough. It is a clean cut. But it not only cuts the tree, but it created a small ravine, that is created by Enma. Zoro's jaw dropped at the destruction that this blade had created.

 He didn't expect it at all. Truly a terrifying sword. Isurugi wasn't exaggerating. His right arm looks like a mummy's arm. But because of his mastery over Armament Haki, he managed to took control over it before putting it back in the scabbard.

"What's with this sword? This sword is truly out for destruction." It did more than it was supposed to. He almost lost control over his Haki earlier. He had never heard of such a sword that could did this.

"This is not going to be easy." Seeing what the sword could do, he realized that controlling how much damage Enma would did to his enemies  seems impossible. It would cause quite the problem if he cannot control it.

"I'm going to tame this cursed sword!" Zoro smiled.
