What do you mean by saying that the corpses I sew are all ominous creatures?

I followed his gaze to the long, jet-black sword, and I had the same thought in my mind.

As someone who has faced life and death many times, I know very well.

If you bring an unfamiliar top-tier magical artifact into actual combat before you have fully understood its temperament and power, it is simply playing with your life.

"it is good."

Without hesitation, I stood up, walked over, and grabbed the knife handle.

"The old street is too crowded, there's not enough room to maneuver."

Let's go to that abandoned sand quarry by the river on the outskirts of the city.

"Let's go!" Li Qing snapped his fingers and casually grabbed his compass from the side and stuffed it into his pocket.

Ten minutes later, the two of us drove out of the old street and sped off towards the outskirts of Jiangcheng.

There were hardly any other vehicles on the outer ring road of Jiangcheng late at night.

About half an hour later, we turned onto a bumpy dirt road and finally parked the car in an abandoned sand quarry right next to the Yangtze River.

This place is far from the city center, and there is not a single light in the surrounding area.

The river wind howled as it swept over the high piles of abandoned sand and gravel, producing a sound like sobbing.

Scattered on the open ground were some rusty iron pipes and scrapped excavator buckets, and the air was filled with the distinctive fishy smell of the river.

"This place is nice, spacious enough, you can do whatever you want and no one will bother you."

Li Qing pushed open the car door and jumped out, looking around.

However, just to be on the safe side, Li Qing still very professionally took out three old copper coins from his pocket.

Then, following the directions of the three powers, he flicked his fingers out.

The moment the copper coin sank into the ground, I could feel a subtle change in the surrounding atmosphere.

Clearly, Li Qing had set up a simple soundproofing and illusion array.

"Alright, the formation is set up. As long as you don't make too much noise, most people won't be able to detect the fluctuations in energy here."

Li Qing clapped his hands, stepped aside, crossed his arms, and adopted a posture of watching a good show.

"Let's begin. Let me see just how powerful this weapon that suppressed the mass grave really is."

I nodded, picked up the black knife, and walked to an open space in the center of the sand quarry.

The night wind by the river made my clothes flutter. I took a deep breath, bent my knees slightly, and assumed a basic standing posture.

The first thing to test is the knife's basic physical properties.

Since the test is on basic physical properties, there is no need to activate the evil energy.

I gripped the hilt of the knife, wrapped in animal hide, tightly with my right hand and slowly raised the blade to eye level.

The blade was entirely black, and it was unclear what material it was forged from.

Although the blade looks thin, it is actually very heavy.

I roughly estimate that the whole knife weighs at least thirty or forty pounds.

For an average person, it would be very difficult to hold it flat with one hand, let alone swing it.

But with my body, which has been strengthened several times, this weight feels just right, and it gives me a very solid and substantial feeling when I hold it in my hand.

I slightly turned my wrist and fixed my gaze on a discarded steel pipe, about the thickness of an adult's arm, that was stuck diagonally in the soil three meters in front of me.

Then, I suddenly exerted force in my waist, and the power flowed through my spine and into my right arm.

I swung the black knife in my hand and slashed diagonally at the steel pipe from top to bottom!

"laugh--"

There was no deafening clang of metal, nor any sparks flying.

I felt as if the blade had cut into a slightly hard piece of butter the moment it touched that thick steel pipe.

The blade encountered no obvious resistance, cutting directly into the steel pipe from one end and sliding out from the other.

Clang!

The severed steel pipe crashed heavily onto the gravel-covered ground.

I sheathed my sword and stood up, bringing the blade close to my eyes for a closer look.

Under that pure, violent slash, not a single visible chip or nick remained on the thin, black blade.

It remains as smooth as a mirror.

"Good heavens..."

Li Qing, who was standing not far away, couldn't help but exclaim in surprise.

He strode forward, squatted down, and picked up the severed steel pipe.

Then, he touched the smooth, mirror-like cut with his hand, his eyes filled with amazement:

"The sharpness is absolutely amazing!"

This is a solid seamless steel pipe. You didn't even need to use your internal energy; you could cut it so smoothly just by physically chopping it.

If that were to strike a person, the flesh and bones would probably be split in two instantly.

I nodded, now having a better understanding of the knife's material.

Moreover, during the sword-wielding process just now, I discovered a very terrifying characteristic.

"Li Qing, did you notice that just now?"

I looked at him and said.

"When this knife is swung, the sound of it cutting through the air is very small, so small that it can be almost ignored."

In addition, it is completely black and does not reflect light at all.

If it were a close-quarters fight in complete darkness...

Li Qing was a smart man. After thinking about what I said, his expression immediately changed, and he replied:

"Silent and invisible!"

In the darkness, the enemy couldn't even see the glint of a blade, let alone hear a sound.

By the time they realized the danger, their heads had already been severed!

This thing is simply a peerless weapon born for night combat and assassination!

"That's right." I nodded in agreement.

For someone like me who frequently uses bone needles, concealment is often more deadly than blatant destructive power.

"The physical performance tests are complete. Next, we'll test its compatibility with the malevolent energy."

I took a few steps back, creating a relatively safe distance, took a deep breath, and my eyes instantly turned sharp.

I closed my eyes, and with a thought, the evil pill in my dantian began to slowly rotate.

As the evil pill circulated, a powerful evil aura surged out along my meridians like a floodgate being opened.

The meridians in his arms, modified by the self-sewing technique, allowed the transmission of this malevolent energy to proceed without any obstruction.

"Buzz—"

The moment I infused the blade with my malevolent energy, the once lifeless black sword emitted a deep, excited hum.

This knife is like a bottomless pit that has been dried up for a long time.

Although it had absorbed so much Yin energy from the mass grave at the bottom of the well, it still seemed to have no limit, greedily absorbing the Yin energy I injected.

Moreover, I could clearly feel that when the faint dragon might belonging to the remnant of the dragon soul spread along the baleful aura into the blade, this originally unruly and fierce weapon immediately conveyed an emotion of complete submission and joy.

To Li Qing's astonishment, the fine, dark forging patterns on its originally jet-black blade began to light up little by little.

However, this time the light that appeared was no longer that bloodthirsty dark red.

Instead, after being assimilated by my jade-colored evil energy, it took on a dark red color with a faint golden luster, looking both eerie and sacred.
