Walking out of the forest all the way, Luo Hao's school uniform became tattered, and he was about to become a beggar. Of course, he didn't gain anything from it.

As he continues to fight with the gigantic flora and fauna, he has become more and more proficient in the use of magic, and he is able to control the size of his magic freely, and the upper limit of power is much greater. The most important thing is that due to eating barbecue meat along the way, the power called [magic] in his body has doubled.

There is still a long way to go from the city where humans gather, and the figure of the huge black stone monument is already clearly visible. Closer to that side, the figure of the black stone monument appears even larger, as long as you look up slightly into the sky, the sky-like iron wall can be seen.

I don't know if it's because of his strength or increased strength, Luo Hao can clearly feel the wonderful fluctuations faintly emanating from those huge black stone tablets. According to Luo Hao's observations, it was precisely because of the existence of these fluctuations that the creatures that could increase the magic power in his body and mutate greatly did not dare to easily approach the dwelling of human life.

This is illustrated by the fact that on the way to human dwellings, the number of mutant creatures is becoming less and less numerous, and not a single figure can be seen at all.

However, these creatures that had strayed from his common sense due to some kind of situation that Luo Hao did not clear did not give up on invading the human area because of the existence of the black stele. They linger a little farther away from the fluctuations emanating from the black stele, ready to attack the human dwelling.

These subtle discoveries also made Luo Hao realize one thing, and also understood why there was such a huge group of black stone tablets in human dwellings. They exist to defend against the beasts of the forest, in other words, humans who are forced to act this way are no match for the mutant creatures in a head-on battle.

Luo Hao didn't know if only the humans here would use this passive means to defend, or if the humans all over the world would use this method to survive. If it's the former, then it's okay to say, if it's the latter, then the world may be very dangerous and terrifying.

The mutant creatures encountered along the way are all low-strength goods, but this does not mean that the mutant creatures in this world are all of this level of strength. Although these are just Luo Hao's boring speculations, if this is the case, he must be mentally prepared accordingly.

"Shak, can other humans or people with power see you?" Seeing the soldiers guarding from afar, Luo Hao whispered to Xia Ke beside him.

Shak smiled confidently: "You can rest assured, except for the Grim Reaper, the existence equal to or higher than the Grim Reaper, no one else can see me." Moreover, if you want to talk to me, you don't have to open your mouth deliberately, as long as you agree, I can read your thoughts directly in your heart. ”

"That's pretty good." Luo Hao nodded.

Although it is unpleasant to be read by others, it is more than a star and a half compared to being treated as a madman by others.

The city was closely guarded by soldiers with real guns and ammunition, but when they saw Luo Hao swaggering into the range of the black stone stele's fluctuation influence, they automatically ignored Luo Hao's existence. When Luo Hao asked for directions, someone was kind enough to show him the way.

Fortunately, what they say is the same language as Luo Hao's world, and even the era of civilization is also a period of modernization, if it is a primitive society or other civilization system, then Luo Hao will be completely blind.

Luo Hao walked all the way into the city.

The breath of modernity rapidly dilutes the breath of nature, and the breath of civilization rushes to the face.

Since the vast expanse of the land is occupied by mutant creatures, humans can only live in this land protected by black stone tablets, and of course, the housing problem will be very tense. As soon as he entered the city, Luo Hao saw that the simple streets were full of pedestrians coming and going, and the population density was very large.

Each of these people was in a hurry, hurrying over and out of the way, as if each of them had something urgent to deal with. Moreover, the vast majority of pedestrians have unhealthy looks on their faces, either because they have not eaten meat for a long time or because they have not taken vitamins for a long time.

Luo Hao thought about it for a while, and then he understood the reason.

Human beings here can only live on limited resources, and the goods they can produce are very limited, unless they are very rich or resourceful, the vast majority of human beings can only rely on their own labor in exchange for a small material life. In this case, being alive is already a great thing, and who cares about being healthy or not!

"Miserable! I actually came to a world with such a complicated situation. Luo Hao wandered around the streets, and just now, he thought of a very urgent matter.

That is, he doesn't have the currency of this world!

In fact, it would be more accurate to say that he doesn't even have anything of value on him now.

Because he was thrown into this world by Xia Ke, Luo Hao didn't even know the basic information of this world, and it was impossible to have the currency of this world. And this means that without money, he will be in a dilemma of not moving an inch in the human city!

However, since it is a city made up of humans, Luo Hao, as a human being, can find a way to live.

There are many ways to get money quickly, in addition to robberies and other behaviors that Luo Hao doesn't want to do, behaviors such as part-time jobs are actually quite good choices.

But before that, Luo Hao felt that he had to go to another place first.

Library!

Books are the ladder of human progress, and this statement is not false at all.

In large and small social groups composed of human beings, the existence of libraries is absolutely indispensable. All aspects of human knowledge, discoveries and skills will be properly kept here, and as long as the library and human beings still exist, there will not be too much fault in human civilization, and human beings will be able to continue to develop in this way.

And for Luo Hao, this is undoubtedly the best place to learn about this world.

Randomly found someone on the street to ask for directions, Luo Hao went straight to the city's library, and he didn't need special identification, so he entered it directly.

As a modern library, in addition to traditional paper books, it is also indispensable to have a new electronic reading room. However, compared to the way of obtaining information through the screen, Luo Hao prefers to look through paper books full of heaviness, so he walked to the place where the books on modern history were stored and selectively picked one to read.

After flipping through several books, Luo Hao found that this world used to be a more technologically advanced civilized world than the world he was originally in, and whether it was economy, technology, or other aspects, it surpassed that world in an all-round way. That all changed dramatically a decade ago, though.

According to these history books, ten years ago, the total population of the world reached a staggering 8 billion, and the technology and economy were very developed. However, one day, a never-before-seen monster appeared without warning and rapidly expanded in number and scale with its terrifying infection ability, breaking out a battle with humanity for survival territory.

It was in 2020 that these monsters, now known as "protozoans", had their first decisive battle with humans. As a result, humanity was defeated, not one in ten people remained, and eighty percent of the earth's territory was occupied by them. Humanity, which once covered every part of the earth, has ceded hegemony.

After that, Luo Hao looked for other books to understand.

The so-called gastrulation is actually a creature born after being infected with a terrifying virus that has a high degree of infection through the blood and can rewrite the DNA of living beings.

As for the name of the virus, it is very succinctly named - protozoan virus.

Organisms infected with the proto-intestinal virus, whether human or animal, will be eroded by the virus that invades the body, and in a very short time, the genetic factors will be rewritten to become new gastrulation organisms.

After being infected, the creature will retain its previous nature, and it will become gigantic and ferocious, and the rabbit that attacked Luo Hao is the original aragula. The most terrifying thing is that the proto-intestinal creatures not only have terrifying powers, but can continue to infect other creatures, and also have a certain degree of regenerative ability, which is simply an undead legion-like existence, and the weapons developed by humans in the past cannot kill them at all.

Eventually, it was discovered that a mysterious metal called "holmium" (pronounced "fire") has a special magnetic field that can effectively weaken the activity of the gastroid virus and deprive the gastrulation of its ability to regenerate. And once the magnetic field is enhanced, it directly has a powerful effect of killing the original aragut.

Based on this discovery, humans have successfully mined a large amount of holmium metal at great expense, and erected huge metal stone monuments around the city. It is precisely because of the existence of these black stone tablets that the proto-intestinal creatures outside who covet human territory dare not approach rashly, allowing humans to obtain the last safe land in the absolute disadvantage.
