21.

As the soldiers prepared to pull the trigger on the man who slaughtered their brothers, cannon fire rained down upon them, killing most of the enemy. Sett looked down at his arms, covered in a black coating, as bullets slowly fell from his hands. He smiled ferociously, seeing his enemies quivering in fear, and quickly reached for his axe and knife.

The man fell under still falling barrage of cannon fire, and Sett finally caught a glimpse of the enemy general, Sellihca, sitting atop his panicking horse, attempting to calm it down. Sett surveyed the battlefield, locking eyes with Sellihca. Sellihca's face twisted with fury as he watched Sett approach.

"On him!" Sellihca screamed to his troops, who were still nearby.

Sett leaped and launched himself over the enemy lines. He could see Sellihca now clearly. Still in the air, Sett took a fast swing and threw his knife toward Sellihca. The knife plunged into Sellihca's horse's eye, killing it instantly. The horse's body, unable to sustain its weight, falls inertly with the force of gravity. Sellihca fell off his mount and tried to stand up, but in those few moments, Sett closed the distance between them and was on him with an ax, swinging it towards his head.

Sett calmly looked at the ax making its way inside the flesh and blood of his enemy. It was a deadly strike, and he was sure of it.

As the ax was about to separate Sellihca's head from the rest of his body, the dead-looking body of Sellihca started to reform itself quickly.

"You cannot kill me, bastard! I have eaten a Mist Mist devil fruit, and now I am invincible!" spat Sellihca, standing up and straightening himself in front of stunned Sett.

Sett looked at Sellihca in disbelief, his ax embedded in the ground. He had heard of the mythical devil fruits, which granted those who consumed them incredible powers. But he had never encountered anyone who had eaten one.

Despite the shock, Sett did not falter. After all, there are a few ways to defeat the devil fruit user. And currently, Sett has two at his disposal. The first one was the Sea stone brass knuckles that he has with himself and still needs an opportunity to test them. And a few moments ago, on the battlefield, he was able to tap into the power that can be used against the devil fruit users. Armament Haki. He is in no way proficient with it, but it is said that the power of Haki evolved in the battle.

Both of them were standing silently on the battlefield. Soldiers around them unconsciously stepped away, giving the place for those two to fight.

Sett lounge at Sellihca with his fists closed, trying again to call at the power of Haki. Sellihca, on the other hand, stood calmly in the face of Sett's assault.

To Sett, the next few minutes were the most frustrating thing he had ever encountered in his entire life. No matter how he struck at his opponent, it did not damage him. All his punches just passed by Sellihca, who didn't even move from his place!

"Didn't I tell you already?" Sellihca caught Sett's hand inside his torso, giving Sett no chance to get away from him. "You can not defeat me, brat!". Sellihca powered his right hand with the power of mist and punched the Sett, simultaneously letting go of his hand, making him fly away from the force behind his punch.

Sett stopped the roll from the fall and slowly stood up. His face was colored with his blood. The soldiers around cheered for their general. After all, it was the first time they saw the blood of this monster that slathered their brothers.

Sett slowly started to lose his calm. It's essential to keep it because currently, only in this state can he use haki. Moreover, nothing he had tried so far worked, and he couldn't make haki work.

'Should I take the brass knuckles? No, I need this fight to get better control over the haki. But I can't even hit him.'

"Brat, you can't win against me," Sellihca said. Sett's anger multiplied by just hearing him speak. "Shut up," said Sett taking a step forward.

"Boy, just forfeit it, you..."

"Just shut UP!!!". Sett interrupted Sellihca, "I promise if you say just one more thing, I will kill you."

"Yeah, I wanna see that happening, kid," Sellihca keeps ridiculing Sett.

Sett couldn't control himself anymore. He didn't remember the last time he felt so enraged. He wasn't so mad even dooring his first few weeks of training.

Sett growled lowly. His hair stood up, giving him the look of a ferocious wolverine. Suddenly the orange-colored static started to flow around him. He gives a picture of pure destructiveness and violence.

"Can you just shut the fuck up!" Sett pulled his right hand and swung it forward with all his might.

The battlefield around him suddenly calmed down. All sound from the surroundings was eaten by this weird uncontrolled orange electricity emanating from his fists. Sett winded up his arm with lightning speed, his muscles bulging with raw strength. As he releases the punch, the air around him seems to ripple and distort like a miniature shockwave.

~~BOOOOM~~

Sett looked between his hand with disbelief and again at the view in front of him. They were the last remaining army of the enemy, and the tents were a huge crater starting from Sett. In front of him was only a carnage. There was no living man, only gushes of blood and clothes here and there. Weapons lay on the side, and Earth was unrooted, living behind a vast crater 10m in width and 300m in length.

One punch. It was all it took to deal with the remaining army.

Sett, still in disbelief, felt weak. He gives his all to this punch, giving it more power, thanks to his boiling emotions. But now he was left with the last remaining strength. If Sillehca reconstructs himself again, he would need to end him fast.

Sett looked at the crater's center and saw the slowly reconstructing misty body of Sellihca. His body still didn't receive any damage. Sett rage left him with the swing of his fists. Now he needs to concentrate calmly.

Sellihca looked with astonishment at the currently empty area around him. He silently cursed. Just one kid stopped all months of planning and preparing for this invasion. Unforgivable.

"What did you do? What was that attack? Did you also eat the devil's fruit?" He asked.

Sett steps forward, systematically tapping on the ground, and in an unthinkable show of speed, he moves behind Silehca. "Wouldn't you want to know hu?"

His hands, covered in a dark-colored Haki, slowly grabbed Silehca's head, and with a quick move accompanied by a sickening sound, Sett broke his neck. Selihca's lifeless body stumbled over the ground.

'Well, that was anticlimactic,' Sett thought. He grabbed the lost axe and severed the head of Sellihca from the rest of his body.

I need to know what I did here. What was that punch? Maybe it was my mink heritage? I will have to talk to my mother after returning.

Holding Sellihca's head Sett turned around and looked at ending battle; he calmly walked back through the battlefield toward the commandment tent.

Dropping head off at the table in front of Egreog, Sett looked at Fox. "Job is done. Let's go."

Both of them left the silent tent behind and took the carriage. They were sure that they left a significant impact on their employer. Soon the jobs will keep raining.

But for now, it's time to go back home.
