A major incident

"Clang--"

The blade sliced swiftly across Wang Hai's abdomen.

But it was just a scratch; there wasn't even a trace of white.

Both of them had anticipated this outcome.

Shen Heng turned his toes and pounced again.

Wang Hai maintained a defensive stance, his arms crossed in front of his chest.

Two figures clashed wildly in the training room, the sound of metal colliding ringing out like a torrential downpour.

"Clang! Clang! Clang!..."

Shen Heng's blade flashed, weaving a silver net, while Wang Hai's iron arm remained as still as Boulder.

Sweat rolled down their foreheads, leaving glistening trails as they moved at high speed, only to be shattered into fine mist by the surging air currents before it even hit the ground.

At a certain moment, accompanied by a 'clang', the two figures, after a brief standoff in the training room, suddenly separated.

After landing and regaining his footing, Shen Heng opened his mouth and gasped for breath.

He looked up at Wang Hai while panting.

Wang Hai was also panting, but compared to Shen Heng, he was clearly much less fatigued.

There was no way around it; Shen Heng was First Tier below him and was primarily an attacker, so it was hard for him not to be more tired than Wang Hai.

"Don't you have a move that can enhance your attack power? Why don't you use it?" Wang Hai asked Shen Heng.

"That move only enhances the sharpness of my blade, but it's not sharp enough to break through your defense, Captain," Shen Heng explained.

While the Vibrating Blade is useful, it's not enough to allow him to surpass this A-Class ability.

That's how it is now, at least for now.

But that's normal.

If he could casually develop a combat technique that could render someone's A-Class ability useless, then abilities would be worthless.

"Can it only increase the sharpness of the blade?" Wang Hai looked at the long blade in Shen Heng's hand, lost in thought.

"Hmm." Shen Heng nodded.

"Show me how to use it," Wang Hai said.

Shen Heng did not refuse upon hearing this.

To give Wang Hai a better view, he held the long sword horizontally in front of him.

He raised his left hand and lightly flicked the longsword.

"Zheng--"

The blade began to vibrate slightly, emitting a faint humming sound.

Shen Heng added another sonic wave, causing the blade to vibrate even more violently, and even leaving a blurry afterimage on the edge of the blade.

Wang Hai crossed his arms and quietly watched the scene unfold before him.

Only after confirming that the longsword was no longer changing did he raise his eyes to look at Shen Heng.

"Is that your signature move?"

"Yes, I named it Vibrating Blade. Currently, it can stack up to three sound waves, but that can only last for a moment. Right now, it can maintain two sound waves continuously," Shen Heng nodded.

Wang Hai nodded slightly, then suddenly stretched out his right arm and slowly pressed it against the blade.

Shen Heng glanced at Wang Hai but did not stop him.

The thick arm slowly slid down in front of the two men, finally colliding with the trembling longsword.

The moment they made contact, a piercing metallic scraping sound erupted in the air, and sparks flew everywhere.

Shen Heng felt a violent recoil force coming from the blade. He tightened his right arm holding the blade slightly to keep it stable.

Wang Hai remained unfazed, letting the blade cut into his skin.

After a moment, he slowly raised his arm.

At the spot where the arm just touched the blade, a white mark slightly thicker than the blade can be clearly seen.

That was caused by the long sword constantly vibrating and cutting at different locations.

But that was all. Even if Wang Hai kept his arm on the longsword, the longsword could not break through his defense.

Wang Hai shook his slightly numb right hand; the white mark on his metallic skin was slowly fading.

He looked at Shen Heng thoughtfully:

"Is your method only supposed to improve sharpness?"

"Hmm, what's wrong?" Shen Heng asked, somewhat puzzled. He had already answered that question once.

"It is indeed sharp enough, but when I placed my hand on it just now, I could clearly feel the vibration transmitted to my hand along the blade. If it had lasted any longer, I might have been injured, but not by the cut, but by the shockwave," Wang Hai said, describing his experience.

Shen Heng was slightly taken aback upon hearing this. He seemed to have some ideas in his mind, but he couldn't put them together.

Wang Hai continued, "That's why I asked you again just now, is this technique only good for increasing sharpness?"

Shen Heng nodded, his mind racing.

Long sword, tremor, force...

He glanced down at the long sword in his hand, which was still trembling.

Can we just get rid of this?

As if possessed, Shen Heng raised his hand and slashed to the side.

This time, he did not deliberately maintain the sonic resonance on the blade, but instead released the vibrating energy outwards like shaking off water droplets.

In Shen Heng's vision, the sound wave slashed outward from the longsword and struck the ground directly.

Then, some of the sound waves penetrated the ground, while the rest rippled across the ground.

Nothing seemed to be happening outside, but Shen Heng's eyes gradually brightened.

In previous simulations, I used the bounce and lingering effects of the tunnel walls to create a superposition of multiple sound waves, thus enhancing my Sound Wave Attack.

Now, isn't wrapping sound waves around the longsword a similar principle?

However, unlike inside the tunnel, where you only need to control the emitted sound waves and the reflected sound waves, it's much simpler.

The sound waves residing on the knife require careful and painstaking control, but...

This is indeed an enhanced Sound Wave Attack, and it's a ranged attack at that.

Just as Shen Heng was considering whether he should give it another try, there was a knock on the door of the training room.

The two looked in the direction of the sound and saw Han Ling push open the door.

Her face showed some panic.

"Captain, Shen Heng, something terrible has happened!"

A few minutes later.

In a dimly lit meeting room that served little purpose.

The members of the Linhai City Supervision Bureau sat on either side of a long table.

(Besides Li Jianguo and Zheng Anlin, who are in charge of logistics, and Wu Cheng, who is on the day shift)

"This is a video I just saw online, take a look."

Han Ling sat on one side of the long table and projected the video she was talking about onto the screen opposite her.

With the hum of the projector starting up, the video image appeared in the center of the screen on the opposite wall.

The first thing shown is the video cover, an image that was clearly filmed at night.

Although the overall tone of the image is dark due to insufficient lighting.

But perhaps because the filming equipment was of high quality, every detail was exceptionally clear.

Thick, grayish-white fog, like a surging tide, occupies two-thirds of the image.

Several streaks of purple lightning flashed within the mist.

But the key point wasn't any of that; it was the gigantic silhouette that was faintly visible through the thick fog...
