The cultivation base is returned ten thousand times, and the starting strength is at the Four Empero

The toxin released by Ningchuan's Poison-Poison Fruit ability spread rapidly.

The entire Impel Down city fell into unprecedented chaos.

There are seven floors in the underwater prison.

There is one floor above ground and six floors underground.

The first floor above ground is where the guards of the large prison are stationed.

The sixth underground floor is a hell where all kinds of serious criminals are imprisoned.

The toxin from Ningchuan's Poison-Poison Fruit spread from top to bottom along the ventilation ducts into the city, and no one could stop it.

Red Lotus Hell, which is the underground level.

The prisoners held there are those who have committed relatively minor crimes.

Although they had committed many crimes at sea, they were nothing compared to the prisoners in the next levels.

Of course, their strength is generally lower.

There is almost no ability to resist Ningchuan's poison.

Therefore, Ningchuan's poison quickly spread to the entire underground floor through the ventilation system.

The prisoners fell to the ground one after another, breathing rapidly, and had no power to fight back.

The guards also struggled in the poisonous fog, but to no avail.

In just a moment, he was completely knocked down by the poison.

As the toxin continues to spread downwards.

The powerful beasts in the second area, the Beast Hell, also gradually fell.

Those ferocious and terrifying beasts were howling and roaring at first, trying to resist the erosion of the poison.

However, they were just stronger animals after all, unable to resist Ningchuan's powerful poison. They gradually twitched on the ground and finally fell motionless.

In comparison, they lasted a little longer than the prisoners.

In the third level of desert hell, the prisoners and guards were not spared either.

The environment here is much worse than the previous two floors. The hot temperature and harsh environment make the prisoners exhausted.

The speed at which the toxin spread caught them off guard.

At this time, with the invasion of poisonous fog, the prisoners fell down defenselessly.

The spread of the poison was almost unhindered.

He sensed that his poison instantly swept across the third underground floor.

A sneer appeared on Ning Chuan's face.

The power of this Poison-Poison Fruit is indeed quite good, and it is most suitable for clearing out these miscellaneous soldiers!

In the fourth level of the Burning Hell, the situation here is no exception.

Those strong prisoners had already been exhausted by the scorching flames here.

Ningchuan's poison further weakened their resistance.

In a moment, all the prisoners here were wiped out and lost their ability to resist.

Poisonous fog filled the air, knocking down prisoners one after another.

As the poison reached the fifth level of the Ice Hell, the criminals imprisoned there found it difficult to resist Ning Chuan's poison.

In this extremely cold land, no matter how hard the criminals hiding in the ice walls struggled, they could not avoid the fate of being poisoned and fainting.

After Ningchuan sensed through his observation Haki that the prisoners on the fifth floor had basically lost their combat effectiveness.

A satisfied smile appeared on his face.

"It's so convenient."

He whispered to himself.

The efficiency of the Poison-Poison Fruit in clearing out the miscellaneous soldiers is even higher than that of the Conqueror's Haki!

After Ning Chuan easily swept through the fifth floor of the prison.

Without hesitation, he walked towards the sixth level of the deepest part of the underwater prison, the Infinite Hell!

This is where the world's most dangerous and evil criminals are imprisoned.

Whether it is a death row inmate or a life sentence prisoner.

Their strength and notoriety far exceed those of ordinary prisoners, and there are many powerful fruit-ability users among them.

Those imprisoned on this floor are the ones that the world government fears the most.

Including Barrett, a subordinate of the former Pirate King Roger, the bloodthirsty vampire Red, and Rain Xilu who can seriously injure Garp.

They are all extremely dangerous people!

Of course, these dangerous people who are feared by the world governments are the perfect candidates for practicing Gu in Ningchuan's mind!

He came to this underwater prison just to capture them!

Ning Chuan slowly stepped into the depths of infinite hell.

As soon as he entered the area near the cells, he heard two angry roars!

"Ningchuan!"

"How dare you come here, you damn bastard!"

Hearing this, Ning Chuan looked back.

It turns out that the person who scolded him was Kaido's subordinate Jack!

At this moment, Jack's voice was filled with anger and unwillingness.

"You damn bastard!"

"I am going to kill you!"

Suddenly, another voice sounded in Ningchuan's ears.

This time the sound came from the aunt’s son Cracker!

He was also full of anger at this moment!

These two people were sent to Tuanbu City by Ning Chuan himself.

So when they saw Ningchuan appear in front of their cell.

Anger suddenly rushed to my heart!

The two of them roared madly and tried to break out of the cage.

However, the seastone chains they wore on their hands made it impossible for them to use their strength.

Ning Chuan faced the two people's roars with a faint smile on his face.

He asked nonchalantly.

"Would you like to reunite with your boss now?"

Jack and Cracker were stunned. They never expected Ning Chuan to say such a thing.

But they didn't have time to react.

Ning Chuan immediately broke their cages and quickly destroyed the seastone shackles on their hands.

Jack and Cracker, who suddenly regained their freedom, were stunned for a moment, and then immediately mobilized the strength in their bodies and prepared to attack Ningchuan.

So that he could vent all the humiliation he had suffered during this period on Ning Chuan!

However, they didn't even have time to make a move.

Ningchuan has already opened the door to the world of Gege.

With a sneer, he kicked them in one by one.

When the other prisoners saw this, they started shouting loudly.

Every person in Infinite Hell is a guy who has committed a big crime.

They long for freedom and to leave this hell.

When they saw Ning Chuan let Jack and Cracker go, they all became jealous!

"Hey, kid! Do you dare to challenge me in a one-on-one fight?"

"If I win, how about you let me go?"

Suddenly, a heavy and provocative voice came from the cell next door.

Ning Chuan looked in the direction of the voice and saw a familiar face.

This is Barrett!

He was once a capable general under the Pirate King Roger and was extremely powerful!

His provocative look made Ning Chuan smile again.

"Barrett, right?"

"Do you dare to make a bet with me?"

"If you can beat me, I'll let you go."

"But if you lose, you will be my subordinate for the rest of your life. I will give you countless opportunities to challenge me!"

Ning Chuan was naturally familiar with Barrett's war-crazy character.

When Barrett was on Roger's ship, he challenged Roger countless times.

But never once beat Roger.

He also fought with Rayleigh quite a few times.

Later on, he even reached the point where he could tie with Rayleigh!

After Roger's death, he turned the whole world upside down in search of a new opponent.

Later, Garp Sengoku and many other masters went there with the Demon-Slaying Order and finally captured him!

Sent to this huge underwater prison.

Until I saw Ningchuan coming!

Barrett sensed the terrifying strength of Ningchuan, and he couldn't help but want to fight with Ningchuan!
