My partner in One Piece is Esdeath

Demon swords can be said to be one of the most terrifying weapons on the sea. They possess unusual powers. Like devil fruits, it is rumored that evil spirits also exist in demon swords, and few people can tame them.

Of course, demon swords and famous swords are not in conflict. A famous sword can be a demon sword, and a demon sword can also be a famous sword.

All the swords of the Ghost Sect headed by the First Generation Ghost are demon swords. Among them, the first-generation Ghost Tetsu and the second-generation Ghost Tetsu belong to the "Twelve Skills of the Supreme Knife Sword" and the "Twenty-one Kung Fu of the Great Knife Sword" respectively.

There were many people who wanted to control the demon sword, but due to lack of strength, they were backfired by the demon sword and turned into killing monsters. They died miserably. Okada Kazuo is a living example.

Annan felt that he might have underestimated Jiang Xue's power.

Although he obtained Muramasa when he was in Nanhai, Muramasa recognized himself from the beginning, so he could easily control it without paying any price. But until now, he still doesn't know why Muramasa approves of him.

But now something is different...

Okada Kazuma looked at Annan who was motionless holding the handle of the knife, his heart was already in his throat, he knew the consequences of failure very well.

"Don't be controlled by Shura." He thought secretly in his heart.

After being eroded by Shura, Jiang Xue has completely turned into a demon sword. If you are not careful, you will not only lose yourself.

Just as he was thinking about it, Annan raised his head slightly, and his red eyes glanced at Okada Kazuma inadvertently.

boom!

Okada Kazuma suddenly froze, a biting chill instantly surged into his heart, and his body began to tremble involuntarily.

"Is this... murderous intent? No, it's Shura!"

He trembled and said unkind words, and at the same time released his hand holding the handle of the knife, looking at Annan in horror.

The moment Okada Ichiro let go, a murderous aura so strong that it was almost visible came from Annan's body, and black flames spread along his arms and throughout his body.

"Shura?"

Annan took two steps back, waved the long knife in his hand, tilted his head, looked at Jiang Xue, and muttered.

"Are you originally called Shura, or will the sword become Shura as long as it is corroded by Shura? Forget it, it doesn't matter anymore. From today on, you will be called Shura."

After saying that, Annan closed his eyes.

boom!

The blood-red murderous aura almost turned into substance, rushing away from Annan's body like a wave. Wherever the murderous aura passed, both guards and prisoners were trembling with fear.

"No one in Impel Down City has such strong murderous intent! Is it Esdeath? Or an intruder?"

On the ground floor, Magellan looked gloomy. In front of him, Ace also had an expression of disbelief.

"Even dad doesn't have such murderous intent...Luffy, be careful."

…………

"Thief hahahaha!"

Tiqi laughed and kicked away the guard who was stepping on his feet. He opened his arms and felt the murderous aura, "Interesting, so interesting!"

…………

"This murderous aura is so mixed that it doesn't seem to be coming from a single person. What did Annan do above it?"

After finishing the phone call with Annan on the fourth underground floor, Esdeath subconsciously raised his head, looked through the ceiling, and seemed to have seen the figure holding a long knife, his eyebrows slightly furrowed.

"Ai... Major General Esdeath, we have found traces of Straw Hat Luffy and are surrounding him!" the guard said to Esdeath.

"Okay, I'll go over now." Esdeath pulled up the brim of his hat and followed the guard towards the encirclement point.

…………

"With this level of murderous intent, how many people have you killed?"

Okada Kazoo, who was shocked by the wave of murderous intent, looked like he had seen a ghost: "You are a navy, how could you kill so many people?"

"I will kill as many people as there have been in Wano Country who died out of hatred in the past twenty years."

The march of King Daxi in his head gradually stopped, and Annan opened his eyes. In his left eye, cyan flames danced, and his red eyes were still staring at Shura.

Black flames suddenly burned on the blade, and the blood-red murderous aura and black flames intertwined with each other on the blade, and finally turned into red-black flames.

"Demon Sword Shura, I accept it."
