Devil Fruit

It's worth mentioning that Rono spent 8 days completing the Hell Training (1). On the fifth day, a storm appeared in the evening. Because he was busy protecting himself, the training was still not completed by midnight, with less than ten repetitions left.

Then, the lightning strike came.

Rono suddenly stopped, then, as if having an epileptic fit, his eyes turned white, his red hair stood on end, his body convulsed, his skin turned red, cracked, and blackened at a visible speed, finally peeling off from his body. With the help of the self-healing factor, Rono's body constantly cracked and regenerated. A burnt smell of protein filled the air. Rono desperately wanted to shout to distract himself, but under the effect of the lightning, let alone speaking, he couldn't even move a finger, only twitching unconsciously. After an unknown amount of time, Rono felt his vision go black and he collapsed on the ground...

After an unknown amount of time, Rono slowly opened his eyes and got up, his expression serious. "System, I'm a bit dizzy. Can I skip training today?" "Beep, friendly reminder, it's 5 AM now." The system paused, "Please complete the training as soon as possible. There are rewards for completing the mission!"

"Damn it, did I overdo it? This kid's mental power is still too low. Hahaha, I should take it easy next time," the system thought to itself.

"System, I have an incurable disease and need a day to recover, ah!" He then lay back on the floor, kicking up a pile of black dust, which was the "skin" he had shed yesterday.

"..."

"It seems he can persevere. No need to take it easy," the system pondered.

"Huh? Why is it a bit chilly?" Rono only then looked at his body. He was naked! Damn it! Rono immediately jumped up, quietly ran back to his room, changed his clothes, and cleaned up the training room. Seeing that the system wasn't responding to him, he could only start a new training session...

Time returned to the present. After completing his day's training, Rono picked up his fishing rod enthusiastically for some sea fishing. Time passed slowly, and it was already afternoon. Rono yawned and pouted, looking at the empty fish bucket. The fish in this sea area were truly smart. It was forgivable that he couldn't catch any, definitely not a problem with his own skills.

"Reel it in!" Rono hummed an unknown song (actually just humming randomly), took off his straw hat, and packed up his equipment. Just as he was about to put it away in the storage room, he heard a shout from the watchtower: "Pirate ship! It's approaching us! Captain!" After a flurry of footsteps, the sailors were assembled, holding their sailor knives and flintlock guns, ready to meet the enemy. Merchant ships usually carried full loads of cargo to ensure profits and couldn't outrun swift pirate ships, so there was only one remaining option: to fight.

"Boom!" A cannonball directly hit the main mast, followed by several chain shots. The pirates, with sailor knives in their mouths, grinned as they climbed onto the merchant ship. "Fire!" The captain drew his saber and shouted loudly. After a round of firing, nearly one-third of the pirates were hit and fell into the water. Before the sailors could reload, the remaining pirates jumped onto the deck, cutting down a sailor with a single slash. The sailors also threw away their flintlock guns and engaged in hand-to-hand combat with the pirates. Captain Asiya was powerful and killed a pirate first. The deck was filled with shouts and the smell of blood and flesh. "Ah!" Suddenly, a flash of a sword cut through, and several sailors were cut in half at the waist, their upper bodies still screaming in agony on the ground. A burly pirate wearing a headscarf, holding a tachi, oh, it's called a sword here, shook the blood off the blade. It seemed this was the attacker. "Captain!" the pirates shouted excitedly, their morale soaring, forcing the sailors to retreat.

"Hah!" Captain Asiya cleaved a pirate with his sword, roared, and charged towards the pirate captain. The pirate captain licked his lips and engaged Asiya in a fierce battle...

And what was our protagonist doing at this time?

A red-haired head (not that Red-Haired) popped out from the pirate ship. He leaped onto the ship and ran straight towards the captain's cabin, yes, the most luxurious one, it was obvious. Arriving at the door of the captain's cabin, he pulled it twice. Huh? Locked? Just as Rono took a step back, ready to kick the door down, a long sword pierced him from behind. Rono froze instantly, slowly lowered his head like a rusty robot, looked at the bloodless blade, tilted his head, clenched his five fingers into fists, and his nails suddenly extended like a feline's, stabbing fiercely backward. With a thwack, Rono felt something slippery. "That evens us out~" Rono mumbled. His hands didn't slow down at all. He yanked it out fiercely, and Extra A behind him fell with a groan, clutching his wound with both hands, looking at Rono with disbelief, his mouth trembling, "De... Devil Fruit!" Then he met his end. Rono touched his already healed abdomen. "Oh dear, another piece of clothing is ruined." He then ignored Extra A, kicked open the captain's cabin door, and rummaged through everything, scratching the walls all over (in case of secret doors). Rono found a metal box in the captain's pillow. "Heh heh, hidden so secretly, yet I found it? If it weren't for my experience... cough cough, caution." He popped out his claws, inserted them behind the box, and cut it open. As expected, two small arrows with emerald green tips lay quietly on top of the items in the box. If he had tried to force it open from the front, he would have most likely died.

He casually tossed the arrows aside and Rono, humming a little tune, began inspecting his spoils. "O.O! Wow! Such a big gemstone, worth a lot of money! Tsk tsk, this dagger, the handle is made of gold! Yo! A Devil Fruit! Haha, this is a huge profit!"

"Kid, I advise you to put down the things, and I can still leave you with a whole corpse." Rono turned his head and saw the pirate captain, covered in blood, panting heavily, aiming a silver pistol at his head.

"Pfft!" Rono made a face, then with lightning speed, took a bite out of the Devil Fruit. "Ugh, it's really f***ing disgusting!" He didn't forget to complain. "Bang bang bang!" The pirate captain was furious and fired off a whole clip. Looking at the bullet holes on Rono's body, he spat. "Damn it, stealing my stuff, and now I've lost hundreds of millions like this!" The pirate captain was heartbroken. He had just encountered a tough opponent, failed to rob them, and then ran back only to encounter this. Just as he was about to call for someone to carry Rono out and feed him to the fish, he discovered...
