I, holding a long sword in my hand, only know one move

[Okay, okay, I knew you were the best to me~ Hey, is this good for yourself? Just kidding - I want a cool new knife too! I'm really not used to that one in your hand...】

"Even if you are accustomed to using it, I will not leave my original intention to you."

[I understand, I understand, I don’t want my wife to be held in someone else’s hands to exert greater power, so I’m jealous? But, but, isn’t what’s mine yours? Hahahahaha! 】

The wanton laughter echoed in his brain. Although he was familiar with the feeling of talking to him a long time ago, the other voice in his head at this moment still gave Cheng Rang a headache.

Maybe it takes some time for me to get used to it... In order not to blurt out another voice in my head like a madman, and be thought to be a schizophrenic and die on the spot, Cheng Rang's words changed during this period. Much less than before.

But even so, from time to time he would make a sound of talking to himself.

"-be quiet."

The man next to him suddenly spoke like this, causing Sima Weizhi to blink in confusion.

"Well, I haven't said anything."

"..."

Cheng Rang glanced at the girl beside him who was looking at him curiously.

"How long until we arrive?"

"Soon."

Her gaze was cast into the distance through the windshield. At the end of the straight and spacious road, a large group of majestic buildings and factories slowly appeared from the horizon in the center of the distant field of vision.

The deposit alone amounted to 30 million, plus conditions that Sima Weizhi could not refuse. The chairman's daughter took Cheng Rang directly to the weapons research and development headquarters of Sima Heavy Industries.

It can be called a willful behavior - but it is because of this that Zhizi Yingyin recommended her to him.

"We're here, Mr. Cheng."

The vehicle stopped steadily, and the tall driver in a suit and leather shoes and sunglasses got out of the car and opened the door for himself and Sima Weiwei in the back seat.

It doesn't seem to be too unexpected...

Looking up at the building with the metal words "Sima Heavy Industry" cast in front of him, Cheng Rang followed Sima Weiwei into the door. Everyone he saw on the road nodded to the young lady.

At this time, an old man with gray hair on his temples, wearing a white lab coat that looked like a researcher, came towards me.

"The eldest lady's sudden visit this time makes me really frightened——"

"You are serious." Sima Weizhi bowed gracefully to the old man, and then introduced: "Mr. Cheng, this is Sima Zhezhen, the general manager of the weapons research department of Sima Heavy Industry. Grandpa Zhezhen, this is... ..”

"Cheng Rang, just call me Cheng."

"Hey, you are such a spirited young man." A bright smile suddenly appeared on Sima Zhezhen's wrinkled face. Although he was already over seventy years old, his eyes were not covered by the mist of twilight at all. Still shining clearly.

"I heard from the eldest lady that Mr. Cheng came here to customize a handy weapon?" He looked at Cheng Rang and then asked.

"yes."

"Then, please come with me."

Sima Weizhi nodded to the two of them: "I will wait for you in the room on the top floor."

Zhezhen walked forward slowly without looking back and waved his hand.

After passing various security checkpoints, Cheng Rang followed Sima Zhezhen into the elevator, and the four accompanying security personnel stood directly outside the elevator.

The ID card on Sima Zhezhen's chest was automatically sensed by the scanning device in the elevator and made a beeping sound. Then he raised his hand and pressed the elevator button. The door closed. With a slight feeling of weightlessness, the elevator began to descend rapidly underground.

On the way, the two did not exchange any words, and apart from introducing each other

When Shao Shi arrived, the old man glanced at him and then never looked back again. He just headed towards a certain destination, which made Cheng Rang feel a little confused.

"Don't you need to ask me what kind of weapon I need to customize?"

Sima Zhezhen's slow but steady footsteps did not pause for a moment. He raised his hand and patted his left hip, which is where Cheng Rang had always carried his sword. He said: "You are a master of cold weapons. Single-edged weapons... .Sword?” (In Japan, sword (剣) represents various cold weapons, including knives.)

"oh?"

Cheng Rang was not wearing a weapon from beginning to end, but the old man in front of him saw through his identity at a glance.

Cheng Rang was very sure that this was definitely the first time he saw him.

[Hey, this old man has two brushes! 】

"Even if they are not wearing weapons, the habits accumulated over the years will make martial arts practitioners such as swordsmen walk differently from ordinary people."

"When you walk, the amplitude of the swing of your left hand is obviously not more than fifteen degrees from the center of the trouser line. From time to time, you will make a virtual handshake because there is no weapon in your hand. The amplitude of the swing of your right hand is further forward. It seems that you use The dominant hand for the sword is the right hand.”

The left hand stabilizes the scabbard and points it straight at the target. The moment the right hand quickly draws the sword, the sword tendon and the cutting line perfectly coincide, achieving a quick and accurate one-shot kill.

"Are you practicing Iai swordsmanship?"

"So..." Cheng Rang retracted his left hand and put it in his pocket.

The secret slashing move, quickly drawing the sword and slashing horizontally - Cheng Rang repeated this action nearly ten billion times in the training ground.

"It's a coincidence that I also know something about swordsmanship - it's just that technology is developing too fast now, and few people are serious enough to use this ancient weapon."

A girl holding a black knife, Tendo Kisara, immediately appeared in Cheng Rang's mind.

Tendo-style sword-drawing technique, the legendary sword demon... holding the murderous sword Yukikage.

He was even able to wield multiple sharp sword energies that could leave his hand, which surprised me at the time.

The silver-white metal door in front of him slid open to both sides silently, and the dark and empty room suddenly turned on, illuminating the place.

"Dojo?"

Cheng Rang looked at the dojo located unknown how deep underground and felt a little strange.

Shouldn't there be high-tech equipment like various weapons processing lines here, as well as researchers in white coats running around holding tablets?

Sima Zhezhen on the side seemed to laugh proudly and waved to Cheng Rang.

"Don't be ridiculous, this is actually my own place to relax and enjoy myself."

"But I'm here..."

The old man waved his hand with a knowing look, "Sign up with me, young man. It's not easy to see a master of swordsmanship. Why don't you allow me to be happy?"

"Don't worry. After our discussion, I will naturally know how to build the most suitable weapon for you."

A bamboo knife wrapped in soft cloth was thrown into Chengrang's arms. Old man Zhezhen casually took off his white coat and picked up another bamboo knife.

"Let me tell you in advance, our bodies are old after all, so just stop there. Mr. Cheng, please."

The old man's clear eyes suddenly glowed with sword light, and the aura on his body instantly transformed into a steel sword that seemed to be contained in a scabbard, which was completely different from the old appearance just now.

The sharpness accumulated in time converged in his slightly stooped body, and the aura exuded made Cheng Rang's skin feel dull pain.

【interesting! Interesting - let me play with him! 】

Another voice in my head was as excited as if it had found the best toy.

"no."

[I won’t kill him, absolutely not~ Please, is this a weapon made for me? So I must spare his life——】

"It's hard to deal with even if you're injured."

【...Woo! Bad, bad, you are bad! 】

"Can you please stop being so disgusting? I'm so sick that I want to vomit."

[Please, I won’t hurt a hair on his head~ After all, I have to ask him to help me create the “most” suitable weapon for me, right? Right~~! 】

Cheng Rang looked at the bamboo knife in his right hand as if he was thinking about it, sighed helplessly in his heart, and closed his eyes gently.

"Okay, I'll give you a minute."

【whee! Love you! I love you the most! 】

Slowly take off the bamboo knife held in your right hand with your left hand, as if facing a mirror, two identical figures appear.

"give it to you...."

[Hey, leave it to me! 】

The voice in my heart broke through the restraints and broke out like glass.

Mixed together without distinction...
