The danger was so great that the enemy was in great danger.

Mu Yun didn't realize at this moment that danger was approaching him.

He was happily strolling on the street with many bags in his hands.

"Well, what should I buy next? How about buying a new set of kitchenware for Witt?"

"Hello, I want to ask you, have you seen this man?"

Just when Mu Yun was thinking about buying a new set of kitchenware for Witt, a hand suddenly reached out from behind and patted him on the shoulder.

Mu Yun turned his head and found a young man with an orange cowboy hat standing behind him.

The young man handed the wanted order in his hand to Mu Yun, and he pointed to the photo on it and asked, "This is the man, have you ever seen him?"

"Monkey D. Luffy, what do you want with him?"

Mu Yun looked at the wanted order of Luffy in the young man's hand and asked.

"You know Luffy, that's great. My name is Ace, I'm Luffy's brother, do you know where Luffy is now?"

Ace looked at Mu Yun happily, he knew he had found the right person, the man in front of him knew Luffy.

Mu Yun looked at the man in front of him who claimed to be Luffy's brother, and murmured in his heart: 'I remember that Luffy seems to have a brother, could it be this guy in front of me? '

Mu Yun was not sure if what the guy in front of him said was true, if he was targeting Luffy, it would be troublesome.

Because he could feel that the guy in front of him was not someone that Luffy and others could deal with.

"Of course I know him. This guy was defeated miserably by me."

Mu Yun casually told Ace that Luffy was defeated by him.

He was not lying. Luffy was indeed defeated by him in the small garden at that time.

"You said Luffy was defeated by you?"

Ace's expression suddenly became serious when he heard the news of Luffy's miserable defeat.

"Yes, the Luffy you are looking for was defeated by me." Mu Yun nodded and said.

"Fire Fist!!"

Boom! !

Ace's arm instantly turned into a raging flame and slammed towards Mu Yun's chest.

The huge flame instantly engulfed Mu Yun, and the flame dragged Mu Yun and smashed him hard against the wall beside him.

"Ahhhhh!"

The people around were so scared that they ran away in all directions.

Even the merchants abandoned their stalls and fled with their heads in their hands. At this time, life was more important.

"Come out! I know you're fine! Get out of here!"

Ace shouted angrily at the broken wall.

He could never forgive the guy who bullied Luffy!

In the collapsed wall, Mu Yun patted the debris on his body and walked out from behind the collapsed wall.

"Really, I almost let you burn my clothes." Mu Yun looked at the clothes he had just bought and complained to Ace.

If he hadn't used his ability to protect his clothes, these ordinary clothes would probably have been burned under Ace's flames.

At this moment, a ball of flames rose inexplicably behind Mu Yun, and a pair of jasper-like horns grew out of his silver hair.

"Luffy actually lost to you, and I, the big brother, will beat you down to avenge him!"

Ace stared at Mu Yun angrily, flames began to emerge from his body, and his hands began to slowly turn into flames.

"Fire Fist!!"

Ace's fist turned into a blazing flame and attacked Mu Yun. This time, the power of the flame was obviously stronger than before.

Maybe Ace was concerned about the innocent people around him and deliberately reduced the power of the flame.

Now the crowd around him has dispersed, leaving only him and Mu Yun, so he can attack without worrying too much.

Looking at the flames attacking him, Mu Yun chuckled.

"Flames are not your patent!"

Mu Yun's arm instantly ignited with flames, and he immediately raised his fist to hit the attacking flames.

"Fire Fist!!"

Instantly, the flames on Mu Yun's arm erupted, and the powerful flames instantly collided violently with Ace's flames.

The temperature around became extremely hot because of the fierce collision of the two flames.

"What?! How could this happen?!"

Ace couldn't believe what he saw. He didn't expect that the guy in front of him could actually produce flames.

Didn't I eat the Flame-Flame Fruit? ? Why can this guy also produce flames? ?

The flames slowly dissipated around them, and Mu Yun and Ace looked at each other.

Mu Yun jokingly stretched out his finger and used the Lunaria tribe's natural fire ability to create a
The small flame danced on the fingertips.

"Don't think that you are the only one who can play with fire. It's easy to raise a flame."

Looking at the flames dancing on Mu Yun's fingertips, Ace's head was bulging with veins.

"You horned bastard! I must beat you up!"

"Try it if you can."

Mu Yun put away the flame in his hand and looked at the angry Ace excitedly.

He hasn't fought with a strong man for a long time. As early as the moment he saw Ace, Mu Yun couldn't help wanting to fight him.

So he kept provoking Ace, wanting to have a good fight with Ace.

"Go to hell! Bastard! Flame Ring·Fire Pillar!"

Ace's body was instantly ignited with flames, and then Ace quickly rotated his body, and the flames quickly rotated with Ace, forming a rotating fire column.

The fire column rotated and attacked Mu Yun quickly, and the surrounding air began to heat up with the rotation of the fire column.

"That's more like it! Come on! Let's have a good fight!"

Mu Yun shouted excitedly as he watched Ace's attack.

Mu Yun raised his arm, and a green airflow was wrapped around his arm.

"Tornado Remnant Cloud!"

Mu Yun threw out the green airflow wrapped around his arm, and the airflow turned into a powerful wind column the moment it left Mu Yun's arm and attacked Ace's fire column.

The wind column and the fire column collided instantly, and the wind column began to burn the moment it touched the fire column, forming two flame vortices that offset each other.

Suddenly, a flame flew out of the fire column and flew towards Mu Yun.

Mu Yun looked at the flame that suddenly attacked him, and quickly reached out to grab the flame.

His arm was instantly wrapped in the armed color domineering, and became a black color shining with metallic luster.

"Armament Haki! How can you have this ability?!"

The flame retreated the moment Mu Yun's arm was wrapped in Armament Haki, and the flame quickly condensed and turned into the appearance of Ace.

Ace didn't expect that there would be someone in the Grand Line who knew how to use Armament Haki.

Mu Yun looked at his empty palm and said regretfully: "I almost caught you, but I didn't expect you to be so vigilant."

"You guy! What happened to Luffy!!"

Ace asked Mu Yun angrily.

Ace, who was not too worried at first, began to worry about Luffy's safety the moment he saw Mu Yun's Armament Haki.

"Who knows? Do you want me to send you to see him in person later?" Mu Yun looked at the anxious Ace and joked.

He could already confirm that the Ace in front of him was Luffy's brother. After all, the expression of worrying about his younger brother could not be acted out.

But he still didn't plan to tell Ace about Luffy's situation. After all, opponents like Ace were very rare.

"Asshole!"

Ace's eyes glared, and a terrifying momentum instantly attacked Mu Yun.

Mu Yun felt the amazing momentum coming, and laughed excitedly: "Hahahaha, Ace, you are indeed a respectable opponent!!"

"Heroic Haki!"

Instantly, a powerful aura burst out from Mu Yun's body, and the two auras collided violently in the air.

Black lightning rose at the center of the collision of the two hegemonic colors, and at the same time a powerful air wave continued to spread around.

"Ace! The ability of Hegemonic Haki is not only possessed by you!!"
