Impel Down, the world's largest prison.

Located in the windless zone in the first half of the Grand Route, security is extremely tight.

The prisoners in the prison are all serious criminals. It is very eerie and scary, and is monitored by various monster guards and video phone bugs.

The entire Impel City is a huge tower-like structure submerged in the sea, with its foundation on the seabed. Since the Impel City is built in a windless zone, the entire Impel City is surrounded by giant Neptunes, and the prison is defended by a fleet of naval battleships.

In the dark area of ​​the prison, there are various cells and torture chambers for prisoners. These cells are made of seastone to prevent prisoners with Devil Fruit abilities from escaping.

In addition, there are a large number of large sea kings on the seabed outside the prison, which gives Impel Down the city the title of "Iron Wall".

Since the establishment of Impel Down, as long as prisoners enter here, no one can escape.

For this reason it is called the world's first prison.

Many people still don't understand why the navy didn't execute the pirates they caught, but instead wasted countless manpower and financial resources building such a huge fortress.

In fact, the role of the impel city is unique and necessary.

The primary purpose is to intimidate, as the name suggests, it is to capture some famous pirates and imprison them forever. This method of punishment is more terrifying than killing.

Sometimes death is not terrible. What is terrible is that there is no hope in the torture. From the moment you step here, it indicates an old age and death in isolation from the world, accompanied by loneliness and despair. What's more, the torture in Impel Down City is unimaginable.

Even some famous pirates are imprisoned here without any hope, so for other pirates, it is the sun in the dark night that is shocking, warning them of the fate of being caught, and swearing the majesty of the world government and navy!

There is another deterrent. The criminals in Impel Down City must have Devil Fruit abilities, such as some powerful abilities. If the navy catches the ability users and executes them directly, then the Devil Fruit will be reborn elsewhere, and they will still be killed by some people on the sea.

People’s income.

This is like a wild fire that cannot be burned out and springs again. As time goes by, new enemies will appear endlessly.

As long as the ability users are imprisoned here, the regeneration of devil fruits can be effectively suppressed. Then there will be fewer ability users in the sea. The effect may not be seen in the short term, but it is definitely feasible in the long run.

There is also the most important purpose, which is research. Every criminal who can enter the Impel City is a good research material. Rather than killing them directly, it is better to use the waste to make scientific appearances.

After all, criminals of this type are tenacious, and as long as they obtain some research results, it will be considerable for the world government.

There are six floors on the surface of Impel City, and each floor has a special meaning and method of torture of prisoners.

The first level of Red Lotus Hell can be understood as piercing.

The second level of beast hell: fatigue.

The third level of hunger hell: hunger and thirst.

The fourth level of scorching hell: burning.

The fifth level of extreme cold hell: cold.

The sixth level of infinite hell: despair.

When criminals enter Impel Down City, they will undergo baptism on the sea level, which is the so-called disinfection baptism in an iron pot with 100°C "hell warm water".

In addition, the purpose of Impel Down City is to make all criminals lose their sense of resistance and become walking zombies like the slaves outside.

As soon as they lose their sense of resistance and become compliant, some criminals are sent to three regular places.

The first one is to be completely brainwashed and transformed into a member of other institutions of the world government. The tasks performed may be assassinations, cannon fodder, and various dark methods may be carried out by these people.

If the World Government is discovered, it can be abandoned at will.

This is a very important force, enough for world governments to take it seriously.

The second is the kingdom of workers.

The Kingdom of Workers is a country on a bridge. It is located in the East China Sea. It is a country on a bridge.

The construction of this bridge began 700 years ago. Most of the countries were people and criminals from countries that refused to join the World Government. People were forced to work hard to build the bridge every day.

Most of the criminals in Impel Down City may also be thrown in.

The third natural option is to be studied as a guinea pig.

Therefore, Impel Down City will not give prisoners a happy life, but will use them as slaves or consumable waste.

The only thing we know is hell. If hell really exists, it must be Impel Down.

In Impel Down City, prisoners were tortured, and some became insane or schizophrenic before they could die.

Among them, new prisoners are bullied by old prisoners.

Are the new prisoners miserable?

In fact, the old prisoners are even worse. The guards inside kill the prisoners at will. If they make the slightest mistake, they will be brutally beaten to death or maimed.

Cooking and frying in oil pans, stabbing to death with swords and trees, biting to death by poisonous insects, hacking to death with axes, bitten to death by wild beasts, etc. are just like the eighteenth level of hell, no different from real hell.

Dark, vicious, crazy, humanity has been lost here.

Prisoners often can't bear it and go crazy, and jailers are even crazier.

Therefore, Impel Down City is also called a mental prison, and any criminal imprisoned in it will eventually become abnormal.

The true role of Impel Down may only be known to a few people. Since the World Government has spent so much financial and material resources, the final result must be that the benefits outweigh the disadvantages.

Six underground levels, infinite hell.

The people who can enter here are all famous people, and the criminals imprisoned are monster pirates who were so vicious that they were erased from history.

The prisoners on this floor are all near-legendary figures, and their fate is either the death penalty or life imprisonment. Because the prisoners on this floor commit many evil deeds, some extremely cruel incidents were covered up by the government, and were even deliberately concealed in newspapers.

It is equivalent to being completely erased, and will be forgotten by the world in ten or twenty years.

Here we have to endure the never-ending darkness, loneliness, and despair...

For those heroes, kings, and tyrants who dominate one side, forgetting is the cruelest punishment.

A few months ago, a big shot was imprisoned here, the aloof red Baloric Redfield.

At the same time, in the past few days, Impel Down City has welcomed another king, and that is the golden lion Shiji.

But today, another king is welcomed, the Pirate King Goldo D. Roger.

The process of being escorted went smoothly. Even though the escort team deliberately slowed down, the journey was calm and no one came to rob us.

This made the already prepared navy extremely uncomfortable.

Even the Sky Pirates had three fleet captains, but the Roger Pirates didn't even have one.

This made Warring States more and more confused, and there was always an ominous premonition.

Because Roger's surrender was really weird.

Time passed very quickly. After escorting Roger to Impel City, Warring States and his party also temporarily stayed in Impel City until there were three days left before the execution.

Six levels under the sea, infinite hell.

It's dark, gloomy, and cold. It's like being abandoned by the world. There is no sound or light. It's like being in a black hole with no sky or earth.

There is no daylight, silence and coldness. It is really like hell and makes people feel heartbroken.

Ordinary people might go crazy after staying here for three days.

"Dong...dong..."

Suddenly, there was the sound of footsteps from a distance, and at the same time, a coal lamp burned with a weak flame from far and near.

Through the faint firelight, you can vaguely see the rows of cells made of seastones, white bones, and withered bones. The whole scene is horrifying.

A figure stopped in front of a cell. Inside, a figure's hands and feet were firmly locked by chains protruding from the wall. At this time, his hair was disheveled and his head was hanging down, as if he was dead.
