Chapter 856: Floating Cities and Artificial Islands on the Sea

If we divide the ratio of monster density in Umbrella Biochemical Test Site, it is probably that urban areas occupy about 80% of monsters, while only 20% of monsters are distributed in suburban areas. This is why Zhang Yanhang has always said that the monster density is not very uniform. The reason is, after all, quite unbalanced.

Moreover, if we analyze the monster density in terms of area, it would be even more unbalanced, because of the 40,000 square kilometers of the Umbrella Biochemical Test Site, urban areas only occupy about 15,000 square kilometers. The suburban area outside the city occupies 25,000 square kilometers.

It can be said that the suburbs are not only large in area but also have a relatively small number of monsters. In a sense, they are very 'empty'.

But it is just empty. Compared with the empty mountain range area outside the Umbrella Biochemical Test Site, the treatment is actually very good. In terms of proportion, there are about 10,000 to 20,000 monsters distributed there.

Naturally, the remaining 70,000 to 80,000 monsters are all distributed in urban areas. This is why Zhang Yanhang said before that some areas in the suburbs may not have a single monster in ten square kilometers, while in urban areas there are some areas. The reason why there are ten monsters per square kilometer is, after all, this is indeed the case.

Therefore, when formulating the cleanup plan for the Umbrella Biochemical Test Site, Zhang Yanhang naturally focused on the urban areas. He planned to clean up the urban areas first, and then clean up the suburban areas.

Moreover, there is also something worth mentioning here, that is, according to Zhang Yanhang's scan, he was very surprised to find that although the number of monsters in the suburbs is very small, the quality of monsters is much better than that in urban areas.

The most obvious quality gap among them is that the lord monster of the Umbrella Biochemical Experimental Site does not stay in the central urban area, but in the suburbs, and it is also the part of the suburbs close to the mountains.

I have to say that this incident really surprised Zhang Yanhang. After all, most of the lord monsters he encountered before were usually in the center of the area, while a few did not stay in the center, such as the Red Iron Queen Ant. As for the red iron ant queen, she also stays at the very back of the ant nest and is guarded by various types of red iron ants.

Only this lord monster of the Umbrella Biochemical Experimental Site actually stayed in such an out-of-the-way, inexplicable place.

But fortunately, the problem is not big. Anyway, Zhang Yanhang did not want to kill the lord monster directly from the beginning, because the density of monsters in the suburbs is smaller, so Zhang Yanhang has already made preparations for the final cleanup, which is the last two stages. Go clear out the suburbs and kill the lord monster along the way.

Because the area of ​​the Umbrella Biochemical Test Site is unprecedentedly large, Zhang Yanhang planned to divide the entire cleanup plan into six stages this time.

When talking about these six stages this time, we have to first mention the topography of the urban part of the Umbrella Biochemical Test Site.

According to Zhang Yanhang's scan results, although this city is ridiculously large, covering 15,000 square kilometers, it is not actually a complete city. Instead, it has obvious chimeric parts, that is, it has annexed other cities. And the adjacent areas in the middle were built, which made the whole city look so big and turned into a super giant city.

During the scanning process, Zhang Yanhang took a look at the name of the main city in the center. The name was very simple and straightforward, and it was called 'Umbrella City'.

Zhang Yanhang even suspected that the reason why this area is called Umbrella Biochemical Testing Site may have something to do with the Umbrella Company, but it is more likely that it was named Umbrella Biochemical Testing Site because of the existence of this city. Umbrella City was built as a biochemical testing ground.

Zhang Yanhang visually estimated that there are at least a dozen cities that were swallowed up by Umbrella City. Among them are small towns, villages, or villages in the city, and there are also counties and cities. However, the area of ​​these small units is generally not too large. The small one is only about a few dozen square kilometers, and the big one is only a few hundred square kilometers.

Therefore, there are actually only two normal cities that were swallowed up that deserve attention, that is, cities at the prefecture level.

The two cities cover almost the same area. One is about 3,800 square kilometers, and the other is about 4,300 square kilometers. Well, it may not be accurate. After all, Zhang Yanhang calculated it through pure visual inspection. But generally speaking, there will definitely be no problem in areas around 4,000 square kilometers.

After all, he is still a fourth-level awakened person, with a hundred points of intelligence, and his brain calculation ability is naturally far beyond that of ordinary people. Therefore, although it is a visual measurement, it is actually about the same as directly measuring with a ruler, and it is not likely to cause too much error. of.

Besides, the shape of each city is irregular. If he can calculate it to this extent, it is considered very accurate. It is not necessary to visually measure the decimal point level. That would be meaningless. After all, the reason why he Scanning the floor area is just a reference for better planning of the cleanup plan.

The name of the smaller city among them is Terra City, and the other larger one is called Grigia City. Zhang Yanhang is somewhat familiar with the names of these cities.

He remembered that Resident Evil Revelations featured a high-tech floating city on the sea, commonly known as a man-made island.

The name of this floating city on the sea is Terra Grigia. Therefore, Zhang Yanhang guessed that the reason why the Umbrella Company named these two cities this way may be to commemorate the city of Terra Grigia.

As for why a good thing suddenly needs to be commemorated, it is naturally because although the city of Terra Grigia is an artificial island in the sea and full of high technologies, it still commits the old habit of putting people first, leaking biochemical viruses and causing biochemical viruses. The crisis turned it into a dead city full of zombies like Raccoon City.

Zhang Yanhang really wanted to complain about the fate of each branch base of the Umbrella Company, which was to leak biochemical viruses, break out biochemical crises, and then zombies sweep across the city, but when he thought about the main focus of Biochemical Crisis is a zombie-fighting game, Without a virus outbreak, where would the zombies come from to fight the players? Then he understood.

Besides, in a normal human city where biochemical viruses do not break out, the power level must be very low, probably only around the first level. It is indeed difficult to be qualified to be selected by the gray world, let alone appear in a fourth-level awakened person like him. in front of me and let it clean up.

After all, Umbrella Company mainly researches biotechnology, and is not very good at various other black technology weapons. At most, it studies energy weapons and so on. After all, he remembers that Umbrella Company seems to have an electromagnetic gun, which can sizzle and emit blue. In addition to giant electromagnetic guns that emit red plasma, there are also laser weapons that emit red laser light.

In terms of planning the cleanup plan for the Umbrella Biochemical Test Site, Zhang Yanhang is planning to target the two cities of Terra and Grigia.

In the first of the six stages, Zhang Yanhang plans to clean up the smaller Terra City. Although this city is small, it has an area of ​​3,800 square kilometers. There is a lucky slot machine on the edge.

After Zhang Yanhang finishes cleaning it, he can just go and play the lucky slot machine to see what good things this lucky slot machine in the high-end area can give.

In the second stage, Zhang Yanhang is preparing to clean up the city of Grigia, which covers an area of ​​4,300 square kilometers. Compared with Terra City, although this city is larger, it has a slightly smaller building density. Some.

Therefore, Zhang Yanhang also likes Grigia City more. After all, the building density is smaller, so he can move more smoothly, or in other words, he will bump into fewer buildings during the movement.

After all, if an ordinary small building with a few floors collides, it will collapse, but if a building with dozens of floors or even hundreds of floors collides, it may affect the subsequent traveling speed even more. After all, a building of this level will fall down easily. Can form a block of hundreds of meters.

But Umbrella City and the cities under its jurisdiction are highly modernized. There are many skyscraper-type buildings that are one to two hundred meters or even higher. If nothing happens later, he will definitely be there when he cleans out the monsters. It caused him a lot of trouble.

After all, even if you can fly, doesn’t flying consume time? That still takes extra time, so for Zhang Yanhang, most of the time it's like 'everything is inferior, only the plains are high'.

After all, there are no restrictions on movement in the plains, which is really cool. But unfortunately, Zhang Yanhang has cleared six areas so far, and he has only encountered the Goblin Plains once in total.

Even after counting the volcano permanent teleportation channel and the Christmas permanent teleportation channel, Zhang Yanhang has actually entered eight areas, and there is still only one plain, the Goblin Plain. It can only be said that among the complex topography, the plain The terrain is indeed quite rare.

To name a few, Raccoon City is a modern city, Demonic Swamp is a forest swamp, small hematite ant nest Daragu, and large hematite ant nest Tarano are all underground nest structures in mineral veins.

The volcano permanent teleportation channel is a large super active volcano. The Christmas permanent teleportation channel is similar to Iceland, with giant ice fields. And the current Umbrella biochemical test site is composed of mountains and valleys.

It can be said that, except for the environment of the small hematite ant nest Daragu and the large hematite ant nest Tarano, there is not even a duplicate environment. This shows that in the face of various complex power systems, When traveling, wanting to encounter the same terrain cannot be said to be a fantasy, but in terms of probability, it is at least a daydream.

But daydreaming is daydreaming, but this does not change Zhang Yanhang's yearning for plain areas, although it is indeed difficult to encounter them.

In the second stage of Grigia City, in addition to the slightly lower building density, which is commonly known as the backward economic development level, Zhang Yanhang also discovered Annihilation in a small town adjacent to Grigia City... The evaluation settlement treasure chest in the Brela Biochemical Test Site area.

Therefore, after he has cleared the second phase of Grigia City and its adjacent towns, he can stop by and check out the evaluation settlement treasure chest of the Umbrella Biochemical Test Site.

In the third stage, even after excluding Terra City and Grigia City, Umbrella City still has 7,000 square kilometers. This area is indeed a bit large, so Zhang Yanhang plans to divide it into two stages to complete.

In the third stage, we will mainly clean up the areas around Terra City and Grigia City, covering an area of ​​3,000 square kilometers to 4,000 square kilometers.

Then the fourth stage is to clean up the remaining area of ​​Umbrella City, that is, the area closer to the center. By then, he will clear as much area as there is left in the third stage until the entire Umbrella City is covered. If the city is completely emptied, he will have completed the entire fourth phase of the cleanup plan.

If it were normal, then after clearing the central area of ​​the fourth stage, Zhang Yanhang would definitely go directly to kill the lord monster in the fifth stage.

But unfortunately, this time the lord monster is located close to the mountains, at the edge of the suburbs.

Therefore, Zhang Yanhang's fifth phase plan is to clean up the suburbs first, clearing out the 25,000 square kilometers in the suburbs at once and then kill the lord monsters.

Although 25,000 square kilometers seems to be a large area, considering that the density of monsters is not high, or in other words, it can be said to be pitifully small, Zhang Yanhang is still confident that it can be cleared out in one go. , after all, there are only 20% of the monsters in the entire Umbrella Biochemical Testing Site.

In the previous distribution process, Zhang Yanhang basically killed about 20% of the monsters in each stage in the first four stages. Therefore, he felt that it was reasonable to kill the last 20% of the monsters in the fifth stage.

Although the area is indeed a bit large, fortunately it is a suburb after all, with no buildings. It is more similar to a plain area. There are no restrictions on movement. In addition, the density of monsters is low, and it will be cleaned up at least twice as fast as in urban areas. .

Moreover, the achievement vending machine is also in the suburbs, or in other words, in a small village in the suburbs. It is really a very small village, probably only a few square kilometers, and there are basically no monster.

But for things like achievement vending machines, Zhang Yanhang has always cleared all the monsters in the entire area before redeeming them. Therefore, he doesn't really care too much whether the achievement vending machines are in the suburbs or the city.

As for the final sixth stage, it is naturally to clean up the area around the lord monster and kill the lord monster accordingly. Then the entire Umbrella Biochemical Testing Site will be completely cleaned up.
