The Demon Instructor Lei En Goes Online, and Bandit Dadan Pees Herself

"Rip Sea Kings apart with his bare hands?"

Instead of thinking Lei En was bragging, Karp's old eyes burst with an intensely fervent gleam.

He had personally tested the kid's strength just now!

That was genuine, monster-level power—powerful enough to make even him break out in a cold sweat!

If he could really hand these two brats who shouted about becoming pirates all day over to him for training...

At that thought, Karp grinned broadly, his smile carrying a hint of relief.

"Wahahaha! Good! Excellent!"

Karp did not bother asking Monkey D. Luffy and Ace what they thought. With a wave of his massive hand, he agreed immediately.

"Since you're so confident, kid, I'll leave these two little punks to you!"

Like he was carrying chicks, he held Monkey D. Luffy, who was still flailing wildly in midair, in one hand. Then he shot out his other hand and grabbed Ace, who had been standing by the door trying to run away.

"Let me go! You damn old man! I'm going to be a pirate!" Monkey D. Luffy wailed, kicking wildly with all four limbs.

Ace clenched his teeth tightly, glaring at Karp with the savage eyes of a lone wolf. He tried to fight back with the water pipe he carried around, only for Karp to suppress him with a single finger.

"From today onward, he's your instructor!"

Without the slightest mercy, Karp tossed the two brats at Lei En's feet like sacks.

"If they dare disobey, beat them half to death! Just make sure they still have a breath left!"

Lei En looked at the two defiant little brats on the ground, wild as monkeys, and clapped his hands in satisfaction.

This start was perfect.

"Don't worry, old man Karp."

Lei En rolled his wrists, his bones cracking sharply. A sinister smile appeared on his face, one so twisted that even the system would call it perverted.

"My teaching methods will make sure they remember this for the rest of their lives."

After saying that, Lei En did not even say goodbye to Makino.

With one hand on each side, he grabbed Monkey D. Luffy and Ace by the backs of their necks—the very napes of their fate.

"Hey! What are you doing?! Let me go!"

"Bastard! Don't touch me!"

The two brats struggled frantically, but before Lei En's dragon-like strength, their resistance was as meaningless as ants trying to shake a tree.

"Shut up. Hold on tight. We're going somewhere more spacious."

Lei En could not be bothered to waste words.

Bzzzt—!

Blinding azure lightning erupted from beneath his feet!

Amid the crackle of violent electricity, Lei En transformed into a bolt of lightning shooting toward the sky, carrying the two screaming brats as he blasted out through the tavern's shattered doors!

Straight into the heavens!

"Ahhhhhhh—!"

Monkey D. Luffy and Ace's shrill cries, distorted by the extreme speed, echoed through the air.

Their destination was Mount Colubo behind the Goya Kingdom!

Deep within Mount Colubo.

This was the territory of the Dadan Family.

At that moment, Dadan stood with her thick barrel waist, a large pipe in hand, barking orders at her bandit underlings with a face full of fierce flesh.

"Stay alert! That damn old man Karp came back from vacation these past two days. If he suddenly decides to come up the mountain, we'll all be in deep trouble!"

At the mention of Karp, the bandits who were usually so fierce all turned pale and nodded repeatedly.

They knew all too well how hard that Marine hero's fists were.

Just as Dadan was about to continue her lecture.

Rumble—!

The previously clear sky suddenly erupted with deafening thunder without warning!

Dadan jumped and looked up.

A blinding blue bolt of lightning, like a meteor falling to earth, came crashing straight toward the clearing at their bandit headquarters with unstoppable force!

"Enemy attack?!"

Dadan's expression changed drastically as she yanked out the massive cleaver at her waist.

"Grab your weapons, boys!"

Boom!

The lightning struck the ground, exploding into a visible wave of violent air!

More than a dozen towering trees around them were instantly snapped in half by the shockwave, while dust and fallen leaves filled the air and blocked their vision.

"Cough, cough... What kind of monster just landed?"

Holding her blade, Dadan stared nervously at the center of the dust cloud, her palms drenched in sweat.

The dust gradually dispersed.

A handsome young man in a black trench coat walked leisurely out of the crater, both hands tucked into his pockets.

At his feet lay two little brats foaming at the mouth, their eyes spinning in circles. They were clearly still recovering from lightning sickness.

They were Monkey D. Luffy and Ace.

"Karp's grandsons?"

Dadan recognized the two unlucky brats at once, though she did not know Lei En.

Seeing that he was only a teenager, Dadan relaxed, only for rage to surge through her immediately afterward.

"Where did this little punk come from?! How dare you make trouble on my turf and break all my trees!"

She waved her huge blade and pointed it viciously at Lei En.

"Do you know whose territory this is? Hand over anything valuable if you know what's good for you, or I'll chop you up and feed you to the dogs today!"

The surrounding bandits joined in, baring vicious expressions as they closed in around him.

Lei En did not even glance at them.

He dug at his ear, his tone filled with undisguised contempt.

"You've got quite a loud voice. Too bad you're pathetically weak."

Lei En slowly raised his right hand and pointed his index finger at half a mountain beside the bandit camp.

"Since this place will belong to me from now on, I should tidy up this ugly scenery a little."

Dadan froze, still unable to understand what Lei En meant.

The next second.

A faint blue arc flickered at Lei En's fingertip.

"Lightning Strike."

Lei En's voice was soft, yet it seemed to carry the magical power to make his words reality.

BOOM—!!!

The sky suddenly split apart!

A terrifying blue lightning pillar more than ten meters wide, carrying world-destroying might, crashed down from the clouds without warning!

The lightning pillar struck that half of the mountain with perfect accuracy!

There was no earth-shaking explosion, only the piercing sound of electric current melting everything away.

Before the horrified eyes of Dadan and every bandit!

That half-mountain, made of solid rock, was forcibly vaporized into nothingness within mere seconds beneath the lightning pillar's heat and terrifying destructive power!

Not even a trace of dust remained!

All that was left was a massive, charred crater so deep they could not see its bottom, molten lava still dripping down from its edges!

Clang.

Dadan's huge cleaver fell straight to the ground and struck her toes, yet she seemed unable to feel any pain.

The entire bandit camp fell deathly silent.

Everyone's jaws nearly hit the ground. Their eyes bulged like bells, their faces filled with the sheer terror of seeing a ghost.

"W-What the hell kind of monster is that?!"

One bandit's legs gave out, and he dropped to his knees with a thud. A warm, foul-smelling liquid spread through his pants.

"D-Divine punishment!!!"

At that scream, Dadan and all the remaining bandits lost every trace of their previous arrogance.

They all dropped to their knees in unison, pressing their foreheads firmly to the ground. Their bodies trembled like sieves, and none of them dared look at Lei En again.

What kind of joke was this?!

He had erased half a mountain with a casual point of his finger!

How was he human? He was clearly a god wearing human skin!

They were just a bunch of backwater bandits without even bounties on their heads. Before him, they were not even qualified to serve as cannon fodder!

Lei En lowered his hand, very satisfied with the result.

He walked over to the trembling Dadan and looked down at her.

"Listen carefully, fat woman."

Lei En's voice was cold without the slightest warmth.

"From today onward, I'm requisitioning this Mount Colubo. This will be my personal training camp."

He pointed at Monkey D. Luffy and Ace, who had only just regained their senses and were still dazed on the ground.

"You pieces of trash will handle logistics from now on. Prepare food for these two brats every day in every way you can, and while you're at it..."

A cruel smile curled across Lei En's lips.

"Serve as their human punching bags."

"Anyone who dares slack off or run away will end up just like that half-mountain."

"Understand?"

Dadan's fat body shuddered. She banged her head against the ground like a pounding pestle, her voice thick with tears.

"Understood! Understood! Please rest assured, sir! We'll make sure the two young masters are fed nice and plump!"

How could she possibly entertain even the slightest thought of resistance now? Keeping her life was already something to thank the heavens for!

At that moment, Monkey D. Luffy and Ace finally came to.

They had also seen the vanished half-mountain. Although shocked, the defiance in their bones kept them from surrendering.

"Bastard! Who wants your training?!"

Ace suddenly grabbed the water pipe from the ground. Like a small wild beast that had been provoked, he charged at Lei En with fierce eyes!

"I'll send you flying, then become the Pirate King!"

Monkey D. Luffy refused to be outdone. He swung his skinny little arms and rushed forward with a loud yell!

Lei En watched the two reckless brats charge at him with bared teeth and claws.

Rather than getting angry, he laughed with immense excitement.

Bzzzt—

Ten blue arcs, like agile venomous snakes, danced merrily across his ten fingers.

Illuminated by the electric light, Lei En's smile gradually became increasingly twisted and sinister.

"Good. You're full of spirit."

He extended both hands toward the two charging boys.

"Then, little brats."

"Hell training begins now."
