City, I'm not a magician

"Could it be a sword pattern? My black sword doesn't seem to have patterns similar to those on Hawkeye Mihawk's black sword and Zoro's Autumn Water. Why is that?"

Yuan Feng looked at the black sword in his hand and found that his black sword was different. Although it was also a black weapon and had become completely black after being blessed by the domineering power, it lacked the patterns that should be there.

"Recall it, and think about it quickly, what is the difference."

Yuan Feng's mind was like fast forward, constantly flashing the various characters in the previous life of One Piece world using Armament Haki or Observation Haki, and finally stopped at an introduction to Wano Country that he had seen before. The introduction of Armament Haki in Wano Country is Ryu Sakura. The boss of the Kuri Gang in Wano Country, Leopard Goro, also taught Luffy how to use Ryu Sakura in the comics.

"Yes, the black sword Shusui is a weapon forged by the swordsman Ryoma using Ryuo. Ryuo can not only attach to the body but also cover the weapon. Wano Country is a country of samurai, so their use of Armament Haki must be more advanced."

Yuan Feng began to close his eyes, and slowly began to let the domineering aura flow through his skin like water, and then gathered in his hands, and slowly passed from his hands to the black knife. In the past, when Yuan Feng practiced the black knife, he would slowly pour all the domineering aura into it.

Just like an empty water bottle, water is poured into it continuously every day, and then the water bottle changes because of the water pouring in, and becomes heavier and stronger. The same is true for the black knife. Yuan Feng simply used the domineering aura to simply strengthen the black knife, but did not make it really sharp as it should be.

And now he is trying the method of flowing cherry blossoms, slowly wrapping the black knife like a stream of water, and the black knife is slowly changing. The sound of the sword keeps ringing, and patterns keep appearing on the blade. The black and red patterns slowly appear on Yuan Feng's black knife. After the smoke and dust passed, Akunolokia looked at Yuan Feng, who had his eyes closed in front of him, and couldn't help but laugh.

"What's wrong? Have you closed your eyes and are ready to die? In that case, I'll grant your wish."

After saying that, Acnologia gathered magic elements on his dragon claws and flew towards Yuanfeng, but Yuanfeng remained unmoved. He kept covering the black knife with his domineering aura to help the black knife complete the black and red lines it should have.

Acnologia looked at the knife in Yuanfeng's hands, which was constantly emitting black and red light, and his heart was also a little trembling.

He could not help but speed up and fly towards Yuanfeng faster.

On the other side of the city wall, the Fairy Tail people had already dealt with all the small dragons in the city, and the rest were being dealt with by people from various guilds, so they all came to the city wall and watched the fight between Yuanfeng and Acnologia, but when they saw Yuanfeng standing in front of them with his back to them, they couldn't help but worry about him.

""Why is Yuanfeng not moving?"

Makarov looked at Yuanfeng in front of him and couldn't help but said worriedly.

Erza didn't say anything but bit her lips and tried hard to hold back the tears in her eyes.

Just as everyone was worried, Acnologia's attack had already arrived in front of Yuanfeng. The girls in the guild had closed their eyes and dared not look anymore. Instead, Erza kept staring with her eyes wide open. She didn't believe that her father would be standing there waiting for Acnologia's attack. There must be a reason.

When Acnologia's attack was about to reach Yuanfeng, the black knife in Yuanfeng's hand began to emit bursts of black and red light. After a flash of light, Yuanfeng disappeared from his original place and appeared above Acnologia. At the same time as the black and red light flashed, a huge dragon arm flew up from the sky, and then fell to the ground with most of the blood.

"Hmm?...How can this be!"

"What happened just now? Why did Yuanfeng suddenly appear in the air?"

"Look, Acnologia's right hand has been cut off."

Makarov and Wojian kept talking, and everyone was so surprised that they didn't know what to say. They just stared blankly at the huge dragon arm that fell to the ground in the distance, and Yuanfeng who was holding a weapon emitting black and red light in the sky.

"Chairman, the black knife in my father's hand seems to have changed."

Erusa's words were like cold water that woke Makarov up. Makarov came to his senses and looked carefully at the black knife in Yuanfeng's hand in the distance. He found that except for the red light that kept shining on the blade, there seemed to be no difference.

"Erza, it seems like there's nothing different except the red light."

"President, didn't you notice that there were no patterns on my father's sword before, it was just a completely black blade.

Erza looked at the black sword in Yuanfeng's hand in the distance and said slowly

"Yes, now that you mention it, I remember that there were no lines on the blade before, but now it seems that black and red lines have appeared all over the blade."

After hearing what Erza said, Makarov looked carefully for a while and found that it was indeed as Erza said, there were indeed lines that were not there before.
