chapter 23

Susanoo's bone arm collided with Jack once again, and this time it was even more terrifying. The pirate boats beneath Jack's feet cracked under the impact. Mu Feng, who controls Susanoo, could feel that Susanoo was on the verge of falling apart.

This is why Jack chose not to continue fighting Mu Feng.

The warship beneath his feet couldn't withstand his own power at all.

"What terrifying power... Is this his true strength!? He truly deserves to be a user of the ancient mammoth fruit." Mu Feng muttered to himself. With the power of a mammoth, if they were on land, Mu Feng wouldn't stand a chance against him. But now, they were on the sea, and Mu Feng thought to himself, "I have a hundred different ways to kill you."

Under Mu Feng's control, Susanoo's fist collapsed. The gray-black stone that was originally held in Susanoo's fist was revealed.

Then, due to inertia, it plunged directly into Jack's flesh and blood. Jack winced in pain, his complexion suddenly changing.

"Hailou stone!? How is this possible!?" Jack exclaimed.

The gray-black stone that Mu Feng had blasted into Jack's body was a Hailou stone. It was the crystallization of the sea and the natural enemy of all Devil Fruit powers.

Mu Feng had obtained this Hailou stone as a reward from the system after killing a sea king class.

As Jack exclaimed, his body continued to shrink.

First, his complete mammoth arm disappeared, followed by his semi-mammoth body. He returned to his original form. The power of the Hailou stone not only prevented Jack from using his Devil Fruit ability, but it also weakened him.

Kneeling on one knee on the deck, Jack's eyes were filled with shock.

He couldn't understand why Mu Feng, also a Devil Fruit user, possessed a piece of Hailou stone and yet remained unaffected by it!

However, he would never have the opportunity to ponder this question for the rest of his life.

Mu Feng controlled Susanoo and landed directly on the Mammoth. In Mu Feng's eyes, Jack at this moment was like a lamb waiting to be slaughtered. Susanoo's terrifying giant fist rained down on Jack's body.

After a few seconds, the system's voice rang in Mu Feng's mind:

"Congratulations to the Host for killing 'Drought' Jack. Reward: Forty-seven advanced experience scrolls. As it belongs to a special life, the Host is rewarded with a mammoth blade."

"Mammoth Blade!?" Mu Feng's eyes lit up upon hearing the system's voice.

It was like a dream come true. His own sword had just shattered in battle, and now the system was rewarding him with a new one. He didn't know how powerful this mammoth blade was, but with a thought, the information about the Mammoth Blade appeared in Mu Feng's mind.

[Item: Mammoth Blade]

[Type: Weapon]

[Quality: six stars][Remarks: The Mammoth Blade can only be possessed by those who defeat a mammoth. It is made by grinding the hardest bones of an ancient mammoth and is even harder than the Hailou stone. Comprehensive evaluation: A tool that is supreme and unmatched.]

"An excellent blade!" Mu Feng couldn't help but feel a surge of excitement as he summoned the Mammoth Blade into his hand.

The blade was about 1.2 meters long, with a width of three fingers. It resembled a large sword.

As he held it in his hand, a sense of relief washed over Mu Feng. It felt as if the spirit of the mammoth had descended into the world. Mu Feng understood that this was the power of a sword.

The Mangekyō in his right eye disappeared, and Mu Feng dismissed Susanoo.

Using Moonwalk, he stepped into the air, performing three air bursts, and appeared directly above the Mammoth!

The pirates under Jack and the Mammoth were completely stunned by Jack's death. They couldn't believe that their fearsome captain, "Drought" Jack of the Beasts Pirates, had been defeated so easily!?

But Mu Feng, who was in the air, wouldn't give them time to recover.

With a single swing of the Mammoth Blade in his hand, a terrifying sword aura was unleashed from the blade... In the next moment, the Mammoth was cleaved in two! The remains of the Mammoth, along with the struggling pirates in the sea, were all turned to dust by the force of the sword aura.

Even the sea itself was cut apart by Mu Feng's sword!

The sword energy extended for thousands of meters, crossing the entire sea. The sword energy didn't dissipate, and the cut in the sea didn't close. The Marines on the battleship were left in awe.

But amidst the awe, there was also an unparalleled sense of honor.

The one who had killed Jack "Drought" and cut through the sea... was their immediate boss. And to be able to follow such a boss, how could they not become famous in the ocean!?

Using Moonwalk, Mu Feng returned to the battleship.

"Clean up the battlefield and return to Naval Headquarters," Mu Feng said calmly.

At that moment, a yellow beam of light shone on the battleship's deck. Kizaru appeared, dressed in a yellow and white striped suit and sunglasses.

"Ah... good old brother Mu Feng. It seems I'm not too late. When I heard that Jack, the 'Drought,' was targeting you, Marshal Sengoku directly asked me, who was on vacation in the West Sea, to come over. Well... let's head back to Naval Headquarters and have a couple of drinks," Kizaru's voice had a peculiar tone to it, no matter how you heard it.

"Senior Polusalino, it would be my pleasure to have a couple of drinks with you," Mu Feng smiled lightly. "However, senior, you're a bit late. 'Drought' Jack has already been taken care of."

"Oh, is that so?" Kizaru lowered his sunglasses and glanced at Mu Feng, surprised. "Oh ha ha... It seems that when you fought against Kuzan, you still had some strength left. You were able to defeat the foolish Jack."

"You have a slight misunderstanding, Senior Polusalino. I didn't just defeat him, I killed him," Mu Feng looked at Kizaru and said with a faint smile.
