All My Superpowers Come from the Law of Causality-Chapter 123: Man and Blade Unity, Super Speed Slash

Afterward, Su Xin tested the influence of barriers on the knife energy through multiple attacks.

Of course, Su Xin also knew that obstacles would inevitably weaken the attack, but what he really wanted to verify was whether the knife energy would dissipate prematurely due to obstacles along the way.

To be precise, would some relatively fragile obstacles cause the knife energy to dissipate directly?

After all, the attack power of the knife energy is actually not strong, and compared to the blade, it is ultimately illusory. Even though it shares the same physical attributes as the blade, essentially it is still illusory and will eventually dissipate, unlike the blade which can continue to attack. For example, once the blade pierces the target, it can continuously apply force and increase damage, but the knife energy obviously cannot.

He needed to confirm the disintegration mechanism of the knife energy, and how exactly it worked.

It couldn't possibly penetrate everything indefinitely along the way, that would be too invincible.

Nor could it dissipate after slashing through a piece of paper, that would be too fragile.

So, it must be a middle ground between the two.

After many attempts, Su Xin finally gained a more thorough understanding of the essence of knife energy.

Just as he had suspected, the knife energy would rapidly weaken due to obstacles.

For example, when he unleashed a knife energy at a book, the knife energy only sliced through five sheets of paper, including the hardcover.

When he slashed the knife energy at a sink full of water, the knife energy barely penetrated through the pool of water, leaving a shallow cut on a cucumber at the bottom.

However, when he directed the knife energy at the cucumber directly, the cucumber snapped cleanly into two, not much different from wielding a physical knife.

So, Su Xin's final research conclusion was that if there are no obstacles, the attack power of the knife energy is not much different from direct attack power. If there are obstacles, the attack power of the knife energy weakens rapidly.

In other words, knife energy can only exert good attack power when facing the first target.

In fact, thinking about it, it's understandable.

Once the knife energy is unleashed, without any continuous external force, and coupled with its inherently illusory nature, each time it encounters an obstacle, much of its force dissipates, making the knife energy even more illusory.

Compared to a tangible blade in hand, the attack power of the knife energy undoubtedly dissipates faster.

And much faster at that.

After gaining a comprehensive and in-depth understanding of the ability "Sword God Slash", Su Xin promptly decided to upgrade.

He now had a total of 2938 causality points, enough to directly upgrade the ability to LV3.

After two upgrades, he obtained the traits "Man and Blade Unity" and "Super Speed Slash" respectively.

[Man and Blade Unity: Choose a knife as the fusion object, which can be reduced tenfold into a mark on the body at any time, and can also revert the mark at any time. However, once the fusion object is changed, the original fusion object can never be fused again.]

[Super Speed Slash: The flight speed of the knife energy is doubled.]

Another option appearing alongside the Super Speed Slash trait was Violent Slash, which can double the slashing force carried by the knife energy.

But anyone with a bit of common sense knows that speed equals power, calculating with the kinetic energy formula known by middle school students, doubling the speed results in quadrupling the kinetic energy, which is much more economical than simply doubling the slashing power, not to mention that a faster flying attack is more difficult for a target to evade.

Therefore, the Super Speed Slash trait ostensibly only doubled the speed, but its actual effect equates to simultaneously enhancing the attributes of attack power, speed, and hit rate.

The appearance of this trait also somewhat addressed the weakness of the knife energy's attack power.

At the very least, using the knife energy to attack is significantly stronger than attacking with the knife itself.

And the other trait, Man and Blade Unity, is equivalent to a portable space, but only for storing one knife.

In the modern society where technology is relatively advanced, this trait proves useful, allowing him to carry a knife with him wherever he goes, undetectable by anyone or any methods.

Given that the fusion object can be freely changed, Su Xin immediately decided to select the only sheathed fruit knife at home as the first fusion object.

The fusion process was very simple.

Su Xin merely held the knife in his hand, and with a thought, activated the Man and Blade Unity trait, and the fusion process quietly ended.

From that moment on, he felt a strange connection, as if the knife had become a part of his body.

"Interesting," he murmured. 𝚏𝕣𝕖𝚎𝚠𝚎𝚋𝚗𝐨𝐯𝕖𝕝.𝕔𝐨𝕞

Su Xin smiled faintly, drew the fruit knife from its sheath, and played with it in his hand before unleashing another knife energy at the wall.

In an instant, a silver knife energy sliced through the air, striking the wall with a low thud, before vanishing without a trace.

"The speed and attack power have indeed increased significantly."

"And it seems easier to wield, could this be a hidden effect of the Man and Blade Unity?"

Su Xin continued to play with the fruit knife, pondering whether it was just an illusion, but the feeling of the upgrade had made knife-wielding delightfully effortless.

Then he sheathed the knife once more.

With a thought, he transformed the fruit knife, sheath and all, into a miniature knife mark imprinted on his left wrist.

Another thought, and the fruit knife mark began to move freely on his arm.

"Nice, this is very convenient."

With a thought, Su Xin moved the knife mark swiftly to his left palm, reverting it to a physical fruit knife that he grasped perfectly.

After amusing himself with the ability for about ten minutes and gaining a thorough understanding of the two major traits acquired from the upgrade, Su Xin stopped.

He took out his phone to check the time—

It was now past 9 PM.

He had been immersed in tasks for over twenty-four hours since last night.

Fortunately, he completed it by November 2nd.

This means, if his judgment on the task trigger mechanism is correct, that the new system task will only trigger again in six days.

"Not too bad, only six days."

"Next, I'll find a way to get a decent knife, after all, now I'm a knife path expert capable of unleashing knife energy at will."

Su Xin chuckled at his self-entertainment.

Returning to his room, he opened his computer and searched online for pictures and data of knives, finally settling on a stylish horizontal blade. He copied the image and relevant data, compressed them into a file, and sent it to Xu Yongshou via a backup email, asking for arrangements to craft it as soon as possible.

In the email, he emphasized using the best materials to ensure sharpness.

After sending the email, he erased all traces, then spent another two hours anonymously donating two million, just as he had done before.

This brought his bank account balance below a million for the first time, indicating that today would be his last day donating, as the remaining over fifty thousand could only be reserved for his daily living expenses.
