The Fourth Civilian Zone, located far outside the Ninth Conservation Circle, is also known as the 'Hot Place'. This is because the entire Fourth District is built on an active volcanic site.

The 4th district of the civilian area, because of its unique geographical location, has high temperatures all year round, with temperatures ranging from 50 degrees Celsius to 70 degrees Celsius during the day and 40-50 degrees Celsius at night. However, the people who live here have adapted to the heat.

It's also because of the high temperature here that the alien monsters that are rampant in other places can't reach here.

If it hadn't happened a year ago, this would have been a haven for humans.

The Fourth Sector, which originally lived on the coast, usually lived by preying on marine creatures, but during an explosion at a nearby abandoned nuclear power plant, it was killed by the Hunters Association's Edla. Dr. Xia assisted in evacuating the original place and moving to the current place of residence.

It is now a four-district area that lives in a basin surrounded by mountains on three sides.

It turned out that the explosion of the nuclear power plant was the same as that of Edla. Dr. Xia deliberately did this in order to force the people of District 4 into the 'experimental base' he had designed.

So as to use the lives of the people of the four districts to complete their various experiments against morality.

The people of Area 4 were used by the doctor to conduct the 'Chimera' experiment, and the failed ones were discarded, and the successful ones were put on tracking chips and put back into natural observation.

Later, the doctor left Sector 4 and left the experiments to his men.

The people of Sector 4 rebelled, killing the Doctor's men and regaining control of Sector 4.

District 4 Managers:

First manager: Herman.

However, under the experiments of the doctor, he was merged with the Nautilus, and managed to survive, and then fled back to the sea, becoming the overlord of the sea in the ocean outside the fourth zone.

Second manager: Neil.

It was Hellman's wife, who did not know that her husband was still alive. Since Heleman's disappearance, he has been in charge of the Fourth Civilian District.

There are four children, the eldest son, Hei Haize, who was killed by a giant cancer in the ocean, two teenage daughters Jenny and Minnie, and a five or six-year-old son, Hela.

After being freed from the Hunter's management, the medical care of Sector 4 was handled by Brafi (female), who had been transformed into a half-lizardman.

The day-to-day manager of the four districts is Sami and is responsible for solving the daily problems of the people of the four districts and protecting the four districts from outsiders.

The captain in charge of keeping the administrator safe is Niel's nephew, Barr.

The fourth zone is:

Ropeway: Located in front of the 4th district, it is a high-altitude ropeway for people to pass through the seaside, and is in charge of Wall (male).

Mountain Gate: Located behind the 4th Sector, it was formerly a road for hunters and executors to enter the 4th Sector. After the 'Edla' incident, the mountain gate was abandoned, and the original Fourth Sector was transformed into a non-human guard by some people who still retained human consciousness to prevent foreign invaders. It was Sammy's younger brother, Sam, who was in charge.

Desert: There is a large area of 'acquired' desertification outside the mountain gate, and there are terrifying monsters 'sandworms' in the desert that have mutated due to nuclear radiation.

Because of its hot and humid location, the 4th district is rich in tropical fruits and crops, and the people here usually rely on these foods, and they also go out to sea to fish.

Explanation of the nouns that appear in the four districts:

Compressed Ice Bomb: A weapon unique to the Hunters' Guild that is used to destroy large areas of xenomorphs.

There are two types: one is the moisture present in the air or objects that can be instantly frozen after the explosion. The other is the 'secondary explosion', in which a shell explodes in two parts, the first explosion sprays a specially treated liquid, and the second explosion freezes objects or creatures contaminated with the liquid.

This shell is small in size and easy to use, and is the most commonly used weapon by hunters, depending on the situation on the spot, the type of shell used is different.

Energy Bomb: It is the strongest weapon developed by the Central Circle after 'that war', and the high-yield energy bomb can form a small black hole in the explosion. It is a forbidden weapon by the World Government and the Hunters' Association.

Energy Stone: A 'modification' of the Energy Bomb developed by the Hunters Association based on the information provided by the Mystery Man, which is smaller in size and less powerful than the Energy Bomb.

Surface cruiser: A controllable flight monitor, usually relatively small, that can use solar energy and cruise satellites to locate and monitor designated locations, and send back topographic maps and high-definition images. The disadvantage is that it can only be used during the day, and there is a time limit for use at night.

Surface Scanner: Similar to the shape of a cruise ship, its function is to scan the specified location for the presence of dangerous goods with infrared. The disadvantages are the same as that of the cruiser, and it cannot be used for a long time at night.

Cruise satellites: Used to support the launched cruisers and scanners, and to connect and transmit data. It can be raised to a certain height and is not easily spotted by the ground. Can be used day and night.

Biological scanners: Vehicle-mounted and portable, portable is handheld, and the biological characteristics of the organism can be known by scanning it.

Light Prison: It is composed of small ground transmitters, and more than three special transmitters can be arbitrarily placed on the ground and set the values of length, width, height and grade, and a cage can be formed by laser columns in the transmitter. It is one of the necessary items for hunters above level 3 (C), and is used to temporarily hold aliens or criminals in a cage.

After two 'nightmares', the erupted volcano was buried forever in the ground, waiting to be discovered by future generations......
