The caretakers of the airport are all very oily and watery jobs, but the situation is different in this North Underworld, there are very few merchant ships coming and going, and they have no oil and water to fish for the official ships.

Chen Ling was generous and gave them so much money at once, how could they be unhappy, they treated them as guests at once, and it was inevitable that they would be entertained.

The entire North Underworld is a big prison, but not the whole island is a prison, in fact, only two-thirds of the area is used to incarcerate prisoners, this area is divided by iron nets, prisoners are strictly prohibited from cross-regional activities, and the remaining one-third is the area prepared for the staff and the staff who come and go, the houses here are better, the facilities are naturally more complete, and the living is naturally more comfortable.

There are quite a lot of staff in the North Underworld, and there are more than 100 houses, or two-story buildings, and it is estimated that there are about two or three hundred people performing their duties here.

Most of the people here are martial artists, but the strength is not particularly strong, the strongest one is estimated to be the city lord of the North Underworld, that is, the warden of this prison, and the strength is only the level of the first-order martial king, this strength can be said to be very, very weak in such a high aura level in the seventh realm, basically when encountering a slightly stronger opponent, it is definitely a character who is killed in seconds, but such a character is already the strongest person in this city, and the rest of the people are even worse, a little stronger is the level of Wuzun, and most people's strength is only Wu Zong。

The overall strength of the prison is really poor.

It can be seen that the vast majority of the prisoners in this Northern Hell Prison are ordinary people, and ordinary strength warriors can easily deal with it, plus this is an isolated suspended island. Even some slightly stronger warriors are not easy to use. I can't escape.

……

Chen Ling and his entourage were warmly arranged in five rooms. Although the people here are still very enthusiastic about the warriors, there is not much difference in treatment, in their opinion, the dancers are all the same, they are just a group of warriors who want to go to the imperial capital quickly.

After arranging their accommodation, I took them to the cafeteria, told them that they could eat here, and left.

"Oh yes, you can move around this area freely, but don't try to enter the prison area. As he was leaving, the man gave them another admonition.

Who wants to go to jail if they have nothing to do. Everyone didn't take it seriously.

Continued to visit the rest of the area, there is really nothing to see on this island, there is no scenery to see, there is no humanity if there is no humanities, there is no building if there is no building, everyone went back to their rooms and began to cultivate.

After five days of waiting, the official supply ship finally arrived.

This ship was sent from the next city that Chen Ling was going to, Tiecheng, and the general route was between the Northern Underworld and Tiecheng, and the only way for martial artists to go to Tiecheng was this spaceship. Because it's an official spaceship, it's actually just an incidental thing. It can be regarded as an official free to do something for the warriors, and there is no charge, but you must obey their arrangements in terms of time, unlike the merchant ships you spend money to hire as fast as you want, and you can let the captain drive slower if you want to slow down.

This is the only ship that can travel between the North Underworld and the Iron City, so there is no choice, no matter what, it can only be like this.

Official supply ships are to stay at the airport for 10 days to unload supplies.

Iron City Iron City, as soon as you hear this name, you know that this city can mine a large number of metal ores, the official supply ship from Iron City is undoubtedly to supply a large amount of metal to the prison, so that the prison can strengthen its own copper walls and iron walls, as for other materials, which need the supply ship of Iron City, Zenith City is only a dozen days away from here, plus the prosperity of Zenith City, the resources are absolutely sufficient, and there is no need to think about anything else.

Chen Ling is not a nosy person, stay for ten days, stay for ten days, no matter how many supplies it has to load and unload, anyway, it will be good to board the ship and leave as soon as the ten days are over.

But one day at lunch, Zhou Lanxin's question aroused his curiosity.

"Husband, it's been the seventh day, and I haven't seen them stop when the supply ship unloads boxes and boxes of supplies, where does the North Underworld need so much metal reinforcement? ”

Zhou Lanxin just asked casually, and Chen Ling also felt a little strange, in the past seven days, so many prisoners have been carrying supplies together, how many materials does Tiecheng have to send here every time?

Metal materials are not consumables like food, and they must need to be replenished every once in a while to maintain normal operation, and this metal material is a non-consumable product, and it will accumulate as much as it comes, where does this northern underworld need so much metal to reinforce?

If so much metal reinforcement is needed, it means that the prisoners in this prison still have some strength, but if so, shouldn't the staff here have stronger strength?

That's a bit weird.

A staff member ate at a long table with them, and couldn't help but smile after hearing Zhou Lanxin's question, and gave them an explanation.

"You don't know how cunning those prisoners in the prison are, in order to escape from the prison, they often dig holes in the ground and abscond to the near the airport, and escape by boat while the spaceship is leaving the port, this kind of thing is not once or twice, in order to avoid such a thing, the warden plans to turn the entire North Underworld into a real iron city, casting an island with metal, so that they have nothing to do, but this project is too huge, you can also imagine. ”

Everyone was stunned, and built the entire North Underworld into a real iron city?

The plan is indeed very ambitious, and if so, it is only natural that so much metal is needed.

……

After eating, everyone went back to continue their cultivation.

The prisoners at the airport are still unloading, and the heavy boxes are so heavy that they are trembling when they walk, but who makes them prisoners, the prisoners in the prison are tantamount to free labor, and I am afraid that Cast Island will also have to work for them, and no one will be sorry if they die anyway.

It was already late after a rainy night with Chen Ling and the three beauties, and they fell asleep soon after panting, but Chen Ling was lying on the bed and heard something wrong.

Normally, there is no sound at night, but why is there a sudden movement of carrying goods tonight? Isn't the task of unloading goods in the prison carried out during the day? Could it be that there are too many goods and we have to work overtime?

Chen Ling pulled up the quilt for them, put on their clothes and walked out.

Walking near the airport, the scene Chen Ling saw was even more strange.

In the middle of the night, instead of unloading, the spacecraft was loaded box by box, and it was either the prisoners who were loading, or the staff of the North Underworld City were carrying the boxes to load the goods...... (To be continued.) )
