I am brushing up materials in One Piece

Kos sat cross-legged alone in the empty dojo. On his lap lay the sailor's knife that he had snatched from a pirate whose name he still didn't know.

Now he was confused, very confused.

It's not that he didn't understand Koushiro's request to let him feel his sword. After all, it's not often said that man and sword are one. Only by understanding one's own weapon can it exert its true power.

But are these too far out of reach for a person like him who has never even entered the door? Logically speaking, isn't "the integration of man and sword" something that masters who have reached the state of transformation should consider?

Is Koushiro trying to trick him?

This idea was thrown out of Kos's mind as soon as it came up, because he knew very well that if Koushiro really wanted to trick him, he would not have said so bluntly yesterday that he did not want to teach him too much.

After thinking about it, Kos decided to give it a try as Koushiro said. After all, he knew that he could not know swordsmanship better than Koshiro.

So he took the long knife out of its sheath, placed his hands on the blade and closed his eyes.

At this time, there were no shouts of children practicing swordsmanship in the dojo, and the location of Shuangyue Dojo was in a relatively quiet corner of Shuangyue Village, so after closing his eyes, Kos received almost no interference from the outside world.

In a suitable external environment, Kos quickly calmed down, and the next step was to feel the knife placed on his leg.

The first thing he felt was the weight. As a fairly good long knife, it naturally had a certain weight, and it could exert considerable pressure when pressed against his leg.

Then there was a thin layer of fine grease on the blade, which was the residue after Koushiro helped with maintenance yesterday. Koushiro also taught him how to maintain it regularly.

no! Concentrate on the knife, don't think about what is there and what is not.

Kos brought his thoughts that were gradually deviating from the topic back on track and continued to seriously feel the long knife lying across his leg.

His fingers moved gently on the blade, feeling the length of the long blade, the convergence angle of the blade, and the sharpness of the blade. He also felt the tandem and handle in detail.

Half an hour later, Kos felt that he had a completely new understanding of this knife, but he still did not understand the reason why Koshiro asked him to do this.

After being unable to have a deeper understanding, Kos's thoughts were still scattered. He exited the meditative state and moved his legs, which were still numb.

"Speaking of which, I haven't given it a name yet."

Looking at the long knife that was temporarily put aside, Kos thought of this problem that he should have realized a long time ago.

"How about calling me Cong Yu?"

Kosi came up with this idea in a playful way, but after thinking that the knife would be broken into two pieces at the beginning, he felt it was a little unlucky, so he had no choice but to give it up.

So Kos began to recall the names of the famous swords in this world, and found that there were full-flavored names such as Wado Ichimonji, Kitetsu, and Yama and Shusui that Zoro would use in the future; there were also names in the red-haired hand. Riffin named the knife after a mythical beast; Hawkeye's black knife night has a bit of a middle-class air; and Roger's way of naming his knife is based on his own wishes, directly calling his favorite knife ACE (Ace).

After thinking for a while, Kos felt that since he was going to choose a name, he should choose it according to the strongest person, so he immediately remembered his wish-to be a salted fish.

"Then let's call you Shang Fang, Shang Fang of Shang Fang's sword."

Kos raised the knife in his hand and said with a smile.

After giving Shang Fang a name, Kos closed his eyes again and felt it. With the blessing of the name, Kos felt that he seemed to have a deeper understanding of the knife in his hand.

Of course, this was just an illusion, and he still had no real progress until half an hour later.

"How's it going? Do you feel anything?"

Koushiro, who entered the dojo, stretched out comfortably and looked at Kosi, who was sitting cross-legged on the dojo with a smile.

"The total length of this knife is about one meter, the blade is about 80 centimeters, the handle is just over 20 centimeters, and it weighs about one kilogram."

As if introducing a product, Kos talked about Shang Fang's general data, then he looked at Koushiro with a wry smile and said,

"That's probably all I felt."

"This is not bad. It has met expectations."

Koushiro smiled and nodded.

"Hey! So this is what you asked me to feel? Didn't you mean to let me become one with my sword?"

Kos stared at Koushiro in disbelief.

"Ah, this ah..."

Koushiro said with an unwavering smile,

"It would be best if you can really get to that point, but generally speaking, as long as you can understand the length, shape, and weight of the weapon you hold in your hand, it's pretty good."

"Is it really necessary to feel and understand things like length, shape and weight? Can't it just be measured with a ruler?"

Kos understands why he needs to use meditation to perceive such easily accessible data.

"It's different. Swords are external objects and do not belong to us. And if you rely on rulers and scales, which are also external objects, to understand them, it is even more impossible to turn them into extensions of your own body, but simply Just waving a stick.”

Koushiro stretched out his hand towards Kos, and after realizing that his target was Shang Fang, Kos stood up and handed the knife to him.

After taking Shang Fang, Koushiro raised his hand to Kos and slashed him head-on.

The knife was so fast that Kos couldn't even close his eyes reflexively when the tip of the knife passed by his eyes.

But it was precisely because he had no time to close his eyes that Cos could see the afterimage left by Shang Fang, which was only a millimeter away from the tip of his nose.

After wielding the knife, Koushiro returned Shang Fang to the stunned Kos with an apologetic face, "I'm sorry, I just think it will be easier to understand if you experience it directly."

Kos, who was still in the shock of the sword strike just now, subconsciously took Shang Fang's hand, and then imitated Koushiro and swung the sword.

As soon as he saw Kos raise his hand, Koushiro took a small step back. When Kos fell together, he was just in a position where he would not be touched by the tip of the knife.

"I see."

After seeing the difference between Koushiro and himself wielding a sword respectively, Kos finally understood Koshiro's intention.

Swords are not organs that people are born with, so if you want to use them like an arm and a finger, you can only feel their weight with your heart and carefully calculate their length. Otherwise, after swinging out the sword, you will not be able to ask "Can it hit?" "Yes?" Where did it hit?" I don't know.

So he closed his eyes and felt the weight of the knife in his hand, then opened his eyes and looked at the distance between Koushiro and himself. After thinking for a while, he swung the knife again.

Koushiro didn't retreat this time, and the tip of Naofang's sword just slipped past the tip of his nose, leaving a short, faint red mark.

"You learn quickly."

Koushiro first nodded with relief, then sighed with regret and said:

"If you are like the age when Sauron came to study with me, you don't have to be so deliberate. As long as you grow up with a knife, you will naturally learn how to hold a knife just like learning your mother tongue. You will have all the information when you do it.”
