One Piece: Starting with just a sword, the crew relies entirely on slashing.

"One-Sword Style - Guardian Blade!"

Sikong Zhen's raging lightning strike, imbued with the power of Heavenly Thunder, was perfectly blocked by Wang Zhe. Wang Zhe himself possessed the power of thunder, although it was not as strong as Sikong Zhen's, it was still able to resist some of its power. In addition, with the protective swordsmanship taught by Shimotsuki Koushirou, Wang Zhe did not suffer the slightest damage.

But both he and Sikong Zhen were exhausted, so the battle ended in a draw once again.

Looking at the famous sword Siming in his hand, Wang Zhe felt a little uneasy. He had been cultivating Armament Haki very smoothly, but perhaps because of the different systems, he was still unable to infuse Haki into the famous sword Siming.

Although this does not affect its ability to unleash powerful attacks, this is the world of pirates, a world where Haki and Devil Fruits reign supreme. Facing these two abilities, it will be extremely difficult for him to fight using the famous sword, Siming.

Seeing Wang Zhe's somewhat dejected expression, Shimotsuki Koushirou, who had walked over from a distance, slowly said, "Every sword has its own mission and attributes. The Blade of Destiny is destined to be a protective blade. It is only suitable for the protective techniques of a great sword. I have already passed on to you all the essentials and insights of the art of killing, but the Blade of Destiny is not suitable for cultivation. I think you need this."

As he spoke, Shimotsuki Koushirou took out the crimson longsword hanging at his waist and handed it to Wang Zhe.

Wang Zhe sheathed the famous sword Siming and took the crimson longsword handed to him by Shimotsuki Koushirou. As soon as he took it in his hand, the crimson longsword burst forth with a dazzling light, like burning magma. The light flashed for only a moment before quickly extinguishing, and the blade at this moment resembled a piece of black iron.

Seeing this, Shimotsuki Koushirou opened his squinted eyes again, his heart filled with excitement. He was now certain that Wang Zhe and this sword would complement each other perfectly.

Wang Zhe looked at the black iron in his hand with great confusion. After a moment, the surface of the black iron cracked inch by inch, revealing the true appearance of the knife.

To be precise, it's more like a longsword, with a black and red hilt, a blade that looks like molten lava, and a dark black tip.

Suddenly, Wang Zhe felt a burning heat all over his body, his mind became somewhat hazy, and his eyes turned blood red without him realizing it. The thought of destroying everything surged into his mind.

Just as he was about to lose control, the famous sword Siming suddenly emitted a deep blue light, soothing Wang Zhe's restless heart like a sea current.

The burning sensation in Wang Zhe's body gradually disappeared, his bloodshot eyes instantly returned to normal, and his somewhat dazed mind cleared up. Wang Zhe looked at Shimotsuki Koshiro with a puzzled expression.

"Master, could this be a demonic sword?"

Meeting Wang Zhe's questioning gaze, Shimotsuki Koushirou smiled and said, "It's not exactly a demon sword, but it's pretty much one."

"This sword was originally forged by my grandfather, Shimotsuki Kojiro, specifically for the killing techniques of a great sword. My grandfather originally intended to forge it into a supreme grade sword!"

"But he failed. Later, my father, Shimotsuki Kozaburo, took over the forging of this sword. He almost succeeded, but the number of Supreme Grade Swords was destined to be only 12. The birth of each new Supreme Grade Sword meant the fall of an old Supreme Grade Sword!"

"My father also failed to complete the forging of this sword, so it has no scabbard or name, and the sword does not recognize my father. After my father passed away, the task of forging this sword fell to me, but I had given up all hope until I met you."

"Just as I suspected, it has accepted you. So, give this sword a name. I believe you can truly elevate it to the level of a Supreme Grade Sword!"

After listening to Shimotsuki Koshiro's story, Wang Zhe became excited. Although the famous sword Siming was very good, he had to find a weapon that could support him in using all his skills in order to fight later.

Wang Zhe glanced at the renowned sword Siming at his waist, then at the nameless sword in his hand, and murmured, "A mighty sword, a guardian, a weapon of slaughter, a sword of slaughter, huh? In that case, from now on you shall be called—the renowned sword Duming!"

As soon as he finished speaking, the famous sword Duming in Wang Zhe's hand seemed to come alive, with sparks emanating from its surface and surrounding Wang Zhe.

As if sensing something, Wang Zhe kept recalling the essence of the great sword's killing technique in his mind. He mobilized the Armament Haki in his body and wrapped it around the famous sword Duming. The famous sword Duming did not turn black as it would normally, but instead, flames with a dark black color mixed with crimson ignited on the blade.

"One-Sword Style - Wildfire!"

With a loud bang, the houses in the distance collapsed and burst into flames.

Although Shimotsuki Koushirou was thrilled by the sight, he still maintained a smiling expression.

Oda, Ryoto Kurosaki, Kazuki Kato, and Naguri, however, were not so calm. Their blood boiled like a distant raging fire, their eyes bulged, and their faces turned red with anger.

"You little brat! My house is gone!" ×4

The four roars brought Wang Zhe back to his senses, who was still immersed in surprise, and he scratched his head awkwardly.

"I'm sorry, everyone, I got a little too excited and couldn't help myself..."

Seeing that things had come to this point, Oda and his three crew members stopped talking and ran off to put out the fire, cursing under their breath.

After the four people left, Wang Zhe breathed a sigh of relief. He was already planning to run away. He kept reassuring himself that he wasn't afraid of trouble, but since his house had burned down, he didn't want to sleep on the streets.

Although only three weeks have passed here, he has already mastered the three types of Haki. It's time for him to go out and develop his skills. Hard training is not as fast as taking up a sword and killing people. Now that he has obtained the famous sword to save his life, it is twice as effective with half the effort.

Although he hadn't mastered the advanced application of Conqueror's Haki, the Entangling Bond, or the Armament Haki, the Flowing Sakura (internal destruction), nor the Observation Haki that allows for future prediction, Wang Zhe was already quite satisfied. These things weren't easy to master; for real instruction, he'd have to find Kaido of the Beasts.

Wang Zhe's greatest gain from this trip was obtaining the famous sword Duming, as well as the essentials and insights of the great sword taught by Shimotsuki Koushirou. He believed that with the famous swords Siming and Duming, he would soon be able to master the ultimate techniques of protection and killing, and perfectly combine them into the true art of the great sword!

Thinking of this, Wang Zhe looked at the famous sword Duming in his hand, and then at Shimotsuki Koushirou, feeling a little curious.

"Master, what level of famous sword is the 'Life-Saving Sword' now?"

Shimotsuki Koshiro replied with a smile, "To be precise, the famous sword Watari is between the peak of the 21 Great Grade Swords and the special famous swords without a clear grade. It is only one opportunity away from becoming a Supreme Great Grade Sword of the 12th grade!"

"Furthermore, some special swords without a clearly defined grade are no weaker than the Supreme Grade Swords, the most famous being the Griffin wielded by the Yonko Red-Haired Shanks!"

"Of course, the other 21 Great Grade Swords may also have the opportunity to become Supreme Grade Swords. It all depends on whether their masters have the ability to bring them to that level."

"As for the 50 Excellent Quick Swords and Quick Swords, if their masters are powerful enough, they can grow into special famous swords without a clear rank. However, this is destined to be extremely difficult. According to my speculation, the Great Pirate King Shiki's Drywood and Ten Cherry Blossoms may have been promoted to famous swords without a clear rank from these two types of swords!"

Hearing this, Wang Zhe understood somewhat. Shimotsuki Koshiro had mentioned that for every new Supreme Grade Sword, an old Supreme Grade Sword would perish. He already had a goal for the advancement of the famous sword, Tomei.

Thinking of the famous sword Siming at his waist, he was also curious whether he could become a supreme great sword through the same method as the famous sword Duming.

"Master, according to your understanding, is the Famous Blade of Fate also a type of famous blade without a clearly defined rank? Does it have the potential to grow into a supreme great blade?"

Shimotsuki Koshiro replied with a smile, "The famous sword Shimei is indeed a sword without a clear grade, and it is one of the top-tier ones. Whether it can become a Supreme Grade Sword is not important, because it is a protective blade in itself and is no weaker than a Supreme Grade Sword."

At this point, Shimotsuki Koshiro paused, his eyes narrowing even more sharply. "Moreover, I have a vague feeling that its grade is even higher!"

Shimotsuki Koushirou's next words startled Wang Zhe, who instantly realized that no one knew better than him just how overpowered the Famous Sword Siming was, since its lack of cooldown meant it was "invincible"!

Although he was very curious about the famous sword, Shimotsuki Koushirou didn't press for details. Thinking about Wang Zhe's progress these past few days, he smiled and said:

"Although the time was short, I have already imparted to you all the essentials and insights of the Great Sword. Only in real combat can you master their ultimate meaning. It's time to leave here."
