Balistic Iaido

[Petra Tentacle> Length: 130(+2) | Kinetic Strength: 50kg(+4)]

Although the long glaive was churning ever brightly, it seemed like Cruciatus himself wasn't particularly satisfied with the existence of dancing red plasma creeping up to his hand.

The flaming liquid dripped to the ground, sparking a blaze. As the flame on the knight's weapon started to get bigger, Cruciatus roared his steel against the sound barrier in the wind, creating a sharp sound of whipping and metal grinding by the air.

The blaze dissipated into the whistling wind.

Unsure of the planned action with his head, Jack kept his adversary busy with flying stones of blaze before diving into the point of no return. The tentacle is rejuvenating as of now, and Jack didn't want to deplete its health yet. Or else, he would be forced to fight with nothing but arms and legs.

'Should I do it? If I miss this swing, then it all will be the end of me.'

[I have a report after cracking a tiny weensy bit of this world's firewall regarding the knight's existence.]

Cruciatus leaped as he spun his glaive like a rotor with the dexterity of his armored fingers. Jack hurriedly dodge-rolled forward, while simultaneously creating another projectile material to be thrown.

'Make a haste!'

Sephiroth dumped his information as fast as he could while trying to make it concise and helpful. Within Jack's mind, it was running at maximum speed.

[Do remember, what I mean by the 'firewall regarding the knight's existence' is because his existence on itself is heavily encrypted by this very world_

[I'm still trying my best to crack more, so try to survive longer and expect more hints. As of now, I only have one news to tell_

[His armor might be shown to be that of degrading steel. I saw you felt more reluctant on striking as hard as you can because of it_

[While in actuality, all of it is made with a similar material with those that accumulate into that of a Soul Teratoma that you've fought.]

Jack dodged another attack from the knight. All while trying to enlarge the 'nope' zone where Jack would try his best to get the hell out when the knight covered that area.

The relentless exchange of metal and flame gradually heated the whole chamber as the flora and flammable object within the vast land was savaged and aflamed asunder by the propelled stones.

'You mean that the armor is actually condensed flesh!?'

[Whatever rolls with your tongue.]

Seeing the vague confirmation, Jack immediately let his flaming tentacle hold the sword once again.

With a stance as balanced as the ground itself, Jack slightly lowered his upper body to prepare for a sudden movement.

His mind was calm, his heart was calm. He didn't even reply to his friend's remark because he was already within the state of pure focus.

Jack was determined.

To capture every information, and use it to conquer the hostile thing in front of him. At that very moment, he mentally removed all of the 'nope' zone that he had declared.

As of currently, he was eight meters apart with the sprinting lancer that was cornering to gain his speed. Calculation began to form within Jack's head, fueled by the realization that he was going to do a move of no return.

Jack had the reflex and perception that could capture and react to a movement in just a 0.09 second the moment it was perceived. It was a lot faster in his prime time. He might be weaker now but the constant state of being wary while scourging the forest had hone him to be able to reach 20% of his best reaction speed.

The average reaction time for humans is 0.25 seconds to a visual stimulus, 0.17 for an audio stimulus, and 0.15 seconds for a touch stimulus. Clearly, Jack might be able to pull his plan off if he was bursted all of his stamina in one go.

His hands formed a hollow grip in front of him, imagining that he was holding the sword instead of a wind. His tentacle was ready. All that he needed now was the timing and the needed velocity.

Estimatedly, Cruciatus would impale him on the chest in just two second of frame time. That was enough for Jack to act, but was he fast enough? Certainly not, but he would be able to fill the speed gap with a certain technique.

What force does exist without needing it to be activated?

Gravity.

He lowered his upper body as if it was falling down to the ground. In the right moment, he was able to lunge forward at faster acceleration within one second timeframe.

One second left before the impale.

Jack had never really understood the meaning and weight behind the value of his tentacle's Kinetic Energy. 50 kg? What weight does it mean? At first, he didn't know it all, and it still was until this moment.

But thanks to the constant usage he did with his extra octopus limb, he could at least determine metaphor for its value. Of course, because he had never truly used his tentacle at its full force, he didn't know the true potential of its strength.

It was definitely not comprehensible when using normal logic. Because it was actually referring to the strength of the weight.

Basically.

It was a multiplier for the value of the tentacle's weight to determine its strength.

His current weight of the tentacle was 16 kilograms. When multiplied by the value of 50, the true strength of the Petra Tentacle would be revealed.

800 kilograms, that was the universal weight of strength for his tentacle—of course, at its maximum capability which includes a broken muscles and a retorting massive pain as a side effect. The average human punch generates around 120-150 psi or 160-204 kilograms of force in total when used to its fullest potential—while a professional boxer could muster up to 350 kilograms of energy in a single punch.

Clearly, Jack's tentacle was far stronger than his original limbs could perform.

In that single moment, Jack dove his upper body further below, accelerating his whole body. His chin was only 3 centimeters from hitting the ground. In just a single moment, he used all of those 800 kg of strength into a snap.

He propelled his sword forward using the full strength of his tentacle—sharp stings ran through his whole spine. With his hand hollow gripping the air, he immediately grabbed the handle of his sword, breaking the imaginative grip by replacing it with the real deal in an instant with a conservative momentum.

Of course, this move put a lot of stress onto the arms' muscles. Let alone catching it, redirecting the sword would need jack to be two times more faster. Currently, his body was following the brute force of the soaring sword by the handle.

A blade that was travelling faster than the strongest strike of samurai's Iaido. As if, the tentacle was the gun and the sword was the bullet that came from it.

At the same time, he was able to slightly dodge the incoming glaive by a thread, creating a non painful scar on his sturdy jacket.

With everything that had been set, Jack redirected the edge of his weapon to the sky.
