Since entering the ancient martial era, human beings have carried out very detailed research and exploration of genetic science. Pen ~ fun ~ pavilion www.biquge.info

Many years ago, human beings divided genes into five levels: S, A, B, C, and D according to the degree of variation.

The higher the genetic level of a person, the greater the potential of the body, and the greater the potential of the body, the higher the probability of becoming a martial artist.

According to the test, Li Hu's genetic grade is A-level, and then it is the highest S-level, and Li Hu's physical potential can indeed be said to be small at a glance.

Of course, this is only a matter of probability, and there are no lack of precedents in history for people with genes that have reached the S level and failed to become martial artists.

According to Lord Martial God, if you want to become a martial artist, in addition to meeting the most basic requirements of physical conditions, you should pay more attention to hard work and understanding, otherwise no matter how high the potential is, as long as the person's understanding and hard work are not enough, he still cannot become a martial artist.

"Huzi, don't be proud, people who can be admitted to the quasi-martial arts school are not simple, take our Central Plains settlement area as an example, there are nearly 500 million people living here, and tens of millions of people participate in the entrance examination of the quasi-martial arts school every year, but in the end only a few tens of thousands can be admitted, it is not an exaggeration to say that it is one in a million, although your physical condition is very good, but it is not that there is no better existence than you, if you don't work hard, whether you can step into the ranks of martial artists has to be said. ”

Li Hu and Wu Xie lived in the Chinese Empire, and there were four major settlements in the entire Chinese Empire, namely the Eastern Settlement, the Southern Settlement, the Northern Settlement, and the Central Plains.

The total population of the four major settlements is 1.9 billion, which is basically equivalent to the population of Huaxia before the outbreak of the World Destroying War.

The Central Plains settlement where the two are located has sixteen acropolises, four main cities and one core city.

Each of the sixteen acropolis had a population of more than fifteen million people, and the most populous acropolis even had 30 million inhabitants.

Each of the four main cities has a population of more than 50 million, and the only core city has a population of less than 40 million.

Don't look at the small number of people in the core city, but because the number of warriors here is the largest, if you really want to talk about combat effectiveness, the sixteen acropolises and the four main cities together are not the opponents of the core city.

The entire Central Plains settlement area is distributed in a ring, and the outermost sixteen acropolises surround the four main cities, forming the first line of defense against the invasion of mutant creatures, and the four main cities surround the core city, constituting the second line of defense against the invasion of mutant creatures.

If the first two lines of defense are breached by mutant creatures, then the core city will be completely exposed to the minions of mutant creatures, and if that time comes, even if the entire Central Plains settlement survives in the end, it is estimated that it will be greatly damaged.

It's ridiculous to say, the core city with the strongest combat effectiveness is guarded by the acropolis and the main city with relatively weak combat effectiveness, if you look at it logically, it should be the core city guarding the relatively weak acropolis and the main city.

The main reason for this ridiculous result is that there is a high class of human beings living in the core city, and there is no shortage of so-called high classes in human society at any time, and since it is a high class, it is natural to enjoy the best treatment.

Compared with humans, mutant creatures are more terrifying, they not only have high defense, but also extremely amazing attack power, it is difficult for human guns and other thermal weapons to cause fatal damage to them, only high-energy weapons, such as laser weapons and electromagnetic weapons, can have an overwhelming advantage in the face of them.

Although humans have developed such weapons, due to the shortage of energy, these weapons cannot be used on a large scale, and they can only be used as a defensive force, and it is very unrealistic to actively attack mutated creatures.

Some people may say: why don't humans use nuclear energy?

The answer is even simpler: since they have been exposed to nuclear radiation, mutated organisms are very sensitive to nuclear energy, and as long as a nuclear power plant is built on the earth, those mutated creatures are like cats that smell fish, rushing to that place, so there is no difference between using nuclear energy and committing suicide.

There was once an island nation called Japan, which was attacked by a large number of nuclear power plants after the World War of Annihilation, and finally attacked by a group of mutated organisms.

It is said that less than a million people survived in the country, and finally joined the Island Alliance to seek refuge, and after so many years of recuperation, the population gradually grew to 50 million, which is only about 10% of the number they had before the outbreak of the war of annihilation.

As for solar energy, before the outbreak of the war of annihilation, human beings built a lot of solar power stations, but due to the extremely serious environmental pollution, the entire sky is covered by thick particles, and it is difficult for sunlight to reach the earth, so the utilization rate of solar energy is very low, and it is not enough at all.

Because of this, humanity will try to compete for resources to develop interstellar navigation technology, and it was widely believed that the only way out for humanity in the future was to leave the earth and build a new home on an alien planet.

However, the level of human technology was lacking, and they finally failed to develop the technology that could carry out long-distance interstellar travel, until finally, the human countries broke out in a war of annihilation under extremely irrational circumstances.

The War of Annihilation can be described as an act of self-destruction by mankind, which not only wiped out more than 80% of the total population of the earth at that time, but also made the originally gray sky even grayer.

As a result, the Earth's climate has become very extreme, with temperatures exceeding 40 degrees Celsius during the day and minus 40 degrees Celsius at night when it is cold.

Nowadays, the term "four seasons like spring" only exists in theory, and ordinary people can no longer see such a beautiful environment. If it weren't for the genetic mutation of human beings due to exposure to nuclear radiation, it would be impossible for us to survive in this extreme climate.

Ordinary people live in the extreme temperature every day, although the body can barely bear it, but the painful torment is indispensable, only to become a martial artist, can rely on super physical fitness, ignore the change of extreme temperature.

Mutated creatures are much more adaptable than humans, and the heat and cold have little effect on them.

In addition, humans have lost their absolute superiority in force and are unable to carry out large-scale elimination of mutated creatures, so their reproduction rate is extremely alarming.

It only takes less than ten years for a small group of mutant creatures to quickly expand into a huge army of mutant creatures.
