Once again, all eyes were on the hand-drawn map placed on the rock. Liu Tang briefly explained to everyone what she knew about the secret base of Paradise Island, the internal structure and regional setting.

What was drawn on the map was the basic information they learned by infiltrating the secret base of Paradise Island twice in the past few days, and it was also the infiltration plan that they were able to provide to Frankmir and the others.

If it weren't for the painstaking and detailed investigation, this huge sewage system would be a labyrinth at all, enough to trap trespers alive in this huge labyrinth.

Liu Tang and Dong Ping studied for three days before they finally found a passage to be able to infiltrate the secret base. However, Frank Mill and the others, perhaps better at dealing with these sewage pipes than Liu Tang and Dong Ping, where many pipes meet, there are some barricades made of steel bars, and it is not easy to break these steel bars to continue to move forward.

Frankimir has a "Gustav heart", which will make their movement very convenient, and they will not encounter the same annoyance as Liu Tang and Dong Ping, which is not worth mentioning for Frankimir.

It's just a pity that now there is a ready-made route, and there is no need for Franky Mill to be the initiator. In short, what they have to do is to quickly pass through the sewage pipe and infiltrate the secret base of Paradise Island.

This road map, with its twists and turns, as complicated as it seems, is able to keep Frankie Mill and them. There is no need to take more unjust paths by mistake.

At the end of the sewage channel, there is a large garbage room and a biogas digester. The stench was enough to suffocate you. If there are no necessary precautions, this is definitely not alarmist.

The garbage room and the biogas digester are connected to a kitchen, which is responsible for providing food to the island's guards, because not only is the location relatively remote, but there are no special guards to guard it, which is a good choice to infiltrate the secret base, of course, provided that you must overcome the complex sewage network. And that pungent stench of decay.

The kitchen is connected to the living quarters of the guards of Paradise Island, and there are basically no guards in that place, so the security level is naturally not high, and no guards need to be sentry in their dormitories.

But that doesn't mean they're going to be able to get around here. It can be said that the entire island guards all live in that area, and it is not easy to pass through it smoothly, and can only wait until the dead of night.

The living quarters of the guards officers. Located on the basement level of the secret base, the distribution of the entire secret base is roughly like this, there are three floors on the ground. All hidden above ground, six floors below the ground, in the Northern Highlands. Due to the elevated terrain of Paradise Island, it is at least four floors underground. All of them are above sea level.

Connected to the living quarters of the guards is the garrison area of the secret base. Judging from the basic situation, there is a large amount of military supplies stored here, and it is also a place for the guards of Paradise Island and their daily work.

There is a special fast lane in the garrison area, which can quickly lead to any layer of the secret base, but to open this path, you need to know the key to open the lane, otherwise you can't enter this lane.

In addition, the most conspicuous place in the garrison area is the huge warehouses with a large number of them, all of which are sealed by polished metal doors, and it is impossible to know what is inside, judging from the grandeur of the momentum, it is enough to place small armed mechs.

In the northeast corner of the garrison, there is a steam system control area, and the only way to access the other levels of the secret base is through the walkway here.

It took Liu Tang and Dong Ping a whole day to find this very inconspicuous passage in the steam control area by mistake.

The function of the steam control area seems to be to regulate the large amount of steam generated by the mechanical heart when it is running, and convert it into heating for the secret base, so as to maintain the temperature in the secret base and keep it in a comfortable environment all year round. The natural climate on Paradise Island is extremely harsh.

That's all they know about the basement. There may be many other paths in different areas who can access other levels of the secret base, but the reality is that they have not yet discovered it.

Liu Tang and Dong Ping are very sure that in the secret base, there is no schematic map, nor any location marking, not even the labeling of the rooms, how each room is used, and who they belong to, perhaps even the staff in the secret base can only be distinguished by their own memory.

Liu Tang and Dong Ping did not have enough time to investigate the above floors, and they only knew about the first to fourth floors underground.

The second basement floor left them with the impression that it was like the administrative office of a government department, and they did not investigate the second basement floor because the time did not allow them to do so. As for the third basement floor, it is also strange, it does not look like a laboratory for professional research and development at all, but more like a hospital with a large number of meeting rooms. Not to mention that they have seen it with their own eyes, there are no less than 20 conference rooms, and as for the other rooms, they are either stacked with all kinds of materials, or they are placed with large and small physical examination equipment, which looks like a physical examination center, so it makes people feel like a hospital.

If you guess correctly, the second and third underground floors should be the main locations of the island's scientific research personnel and daily offices, and there is nothing special about that place, and you can't see it at all, it is actually a secret base, and it is really like walking into a lot of hospitals.

As for the basement four, the situation is completely different, compared to the first to third basement floors, the basement four is a literal prison.

The four underground floors are not only dark and damp, but also densely distributed, countless iron cages, and more heavily armed guards, wandering back and forth in the four underground floors, compared with the above three floors, the security guard there has not only been raised to a level.

Due to the very strict security on the fourth underground floor, Liu Tang and Dong Ping had not thought of a way to break through for a while, so their investigation results could only end here.

If they try to break the barbars and the prison doors, they will only end up undoing all their efforts. Once someone discovers that the barbed wire and the prison door have been breached, they will inevitably think that someone has infiltrated Paradise Island, and if Paradise Island guards and launches a carpet search, they will have nowhere to escape.

The reason why they can stand here now is because they have taken advantage of the loopholes of the guards of Paradise Island, and the guards of Paradise Island can't believe that even one or two of them can have the courage to enter Paradise Island alone. (To be continued......)
