Terrifying Endurance, Taking Six Kings' Spears Head-On?

"Gate of Rest of the Eight Inner Gates!"

Natsuya pressed his chest, activating the Door-Door Fruit's ability to once again open a valve within his body!

At this moment, an even more intense surge of energy erupted from Natsuya's body, swirling outward to form a gale.

Rob Lucci's hair was whipped up by the wind, only to settle back down a moment later.

Right now, a look of gravity flashed through his eyes once more.

He still could not fathom what kind of ability Natsuya was using.

However, that ominous premonition was growing stronger by the second.

To him, Natsuya seemed to have changed in some subtle way.

But naturally, Rob Lucci could not retreat now.

As he had said before, he refused to believe that Natsuya could still turn the tables.

When it came to stamina, as a Zoan-type fruit user, he held an absolute, crushing advantage!

Of course, after what had just happened, Rob Lucci dared not underestimate Natsuya any longer.

At this moment, he immediately employed a more energy-efficient technique.

"Life Return: Paper Art Martial Body!"

Rob Lucci let out a low shout, and his muscular frame suddenly shrank, appearing leaner and more humanoid.

This was a fruit ability technique he had developed in conjunction with the Six Powers.

Although he remained in a half-man, half-beast form, shrinking his body toward a human shape allowed him to reduce energy consumption while simultaneously increasing his speed.

Once the transformation was complete, Rob Lucci flashed forward again, launching an assault on Natsuya.

Seeing Rob Lucci's transformation, Natsuya raised an eyebrow, but he said nothing, meeting the attack with an inexplicable smile on his lips!

Bang! Bang! Bang!!!

"Finger Pistol: Spotted!"

"Rapid-Fire Finger Pistol!"

The two clashed fiercely once again.

Soon, a faint smile appeared on Rob Lucci's face.

"Hmph, playing tricks."

He had thought Natsuya was using some new ability, but upon resuming the fight, he was stunned to discover that Natsuya's strength hadn't changed at all!

It was exactly the same as before!

So, was he just putting on a show, playing tricks?

Realizing this, Rob Lucci felt his confidence return.

If Natsuya was merely bluffing, then the winner of this fight would undoubtedly be him!

Yet, half an hour later, Rob Lucci's expression grew slightly uneasy.

An hour later, Rob Lucci's face darkened.

Two hours later, the shock on Rob Lucci's leopard-like face could no longer be concealed.

"How is this possible!?"

He stared at Natsuya, who was still locked in an endless struggle with him, his eyes filled with utter disbelief.

Setting aside the time spent fighting earlier, let's just count from the moment Rob Lucci activated his Paper Art Martial Body.

Natsuya had been fighting him intensely for a full two hours!!

Two hours! What kind of concept was that!?

That duration was simply astonishing!

Of course, for some powerhouses, fighting for days and nights was not an issue!

But don't forget, the intensity of the combat between these Six Powers superhumans was no joke!

The Six Powers, while powerful, consumed a massive amount of stamina to execute!

Yet Natsuya had been using the Six Powers to fight him for two full hours!

Even Rob Lucci, who was using the Paper Art Martial Body, was starting to feel the strain, but Natsuya still looked as if he had energy to spare!?

How could this be!

Meanwhile, Kalifa, who was watching from the sidelines, was also feeling immense shock.

So much time had passed that she had naturally already rescued Blueno and Kaku.

However, because she had to "take care" of the two of them, she could not spare a hand to "assist" Rob Lucci.

Of course, despite this, Kalifa still believed that Natsuya had little chance of winning.

After all, Rob Lucci was the strongest in the eight-hundred-year history of CP9!

Natsuya could absolutely not defeat him!

Perhaps, if he fled, there might be a sliver of a chance.

Yet, what Kalifa never expected was that not only did Natsuya not flee, but he actually engaged Rob Lucci in a fierce battle.

This intense combat had already lasted for two hours!

Setting aside the odds of winning, the mere fact that his stamina rivaled Rob Lucci's was enough to shock anyone.

However, Natsuya found this completely unsurprising.

Because this was the effect of the Gate of Rest!

It lifted the limits on physical fatigue, overdrawing the body's energy to restore stamina, and offsetting the fatigue caused by the energy consumption of opening the gates.

In short, it neutralized the side effects of opening the gates.

Of course, this did not completely negate them; it would still cause damage to the body, but at the very least, for the time being, Natsuya's sustained combat capability was greatly enhanced!

And this was the reason he had been able to battle Rob Lucci until now!

He could even hold out for longer!

Just like that, Natsuya continued to battle Rob Lucci with ease.

After another moment, Rob Lucci began to struggle.

It was not that he could no longer hold on, but rather that he had no idea where Natsuya's limits lay.

What if Natsuya truly could hold out longer than him?

Thinking of this, Rob Lucci hesitated no longer and let out a low shout.

"Life Return: Release!"

His body suddenly expanded, returning to his original muscular form, and then, with a single step, he charged toward Natsuya like a tank!

"Finger Pistol!"

"Flying Finger Pistol: Draw!"

"Tempest Kick: Triumph Bird!"

Rob Lucci's sudden burst of power immediately put Natsuya at a slight disadvantage.

Noticing this, Rob Lucci's spirits lifted, and he hurriedly pressed his advantage.

In truth, Natsuya's strength after opening the gates was still somewhat inferior to Rob Lucci in his human-beast form.

When it came to a real clash, Rob Lucci was definitely the superior one.

Consequently, even though Natsuya launched counterattacks, he was still suppressed by Rob Lucci.

Realizing this, Rob Lucci could not help but feel a surge of joy, yet at the same time, he felt a bit frustrated.

If he had fought this way from the start, he wouldn't have needed to battle Natsuya for so long.

Of course, even if he wanted to fight all-out, it still depended on whether Natsuya would allow it.

The proficiency of Natsuya's Door-Door Fruit in evasion was, after all, a nuisance.

So this time, he intended not to give Natsuya another chance to escape, but to suppress him directly!

"Rokushiki Ultimate Technique: Six King Gun!"

The next moment, Rob Lucci seized the opportunity, suddenly Shaving to appear before Natsuya, and brought his hands together to release a massive shockwave!

BANG!!!

Amidst the deafening sound, Natsuya's entire body shuddered.

Kalifa's expression changed; such a terrifying attack from a Six Powers ultimate technique could not be defended against, even with top-tier Iron Body!

But immediately after, she was astonished to see Natsuya's staggering figure suddenly steady itself.

A visible green energy surged forth from within Natsuya's body.

That is!?
