Three hundred years ago, the standard of living of human beings was booming. Various scientific and technological achievements are constantly emerging, and intelligent and efficient networks are changing all aspects of people's lives. Countless probes have flown to remote planets, and mankind has embarked on a great journey of migration to outer space.

But just when they were immersed in the beautiful life brought to them by science and technology, in the corner of the universe, an unknown disaster quietly arrived at Dahongxing.

"It was recorded as a midsummer night, and countless meteors streaked across the sky." Zong Zheng whispered, the expression on his face became painful, "The situation at that time did not attract enough attention from everyone, it was just an ordinary meteor shower, and it was not until a month later, when the planet we live on has completely changed, that people realize that all this can be traced back to that night......"

"The first beast to appear was a flying beast! This is a large group, the vast majority of which are small insects, of course, including some mammals whose individuals are not very large, these monsters have a common characteristic, that is, they have sharp fangs, and are extremely bloodthirsty, they live in groups, often in the thousands, everywhere they go, such as locusts transiting, and afterwards corpses are all over the field. ”

As he spoke, Zongzheng's expression trembled slightly, and he could imagine how cruel the scene was when a black monster appeared in the sky.

"One day, just one day later, at least a billion casualties have been caused all over the Great Hung Star! This does not include the death of a large number of livestock and wild animals, on that day, the entire medical institutions of the Great Hung Star were paralyzed, and even the sky seemed to be blood red. ”

"People wept and wailed, basking in the grief of losing their loved ones. Everywhere there are soldiers who come to the rescue......"

When Jiang Mu heard this, a moving expression appeared on his face, and he asked, "Then what happened later?" ”

"Later?"

Zong Zheng fell into remembrance again and continued: "At that time, human society realized the seriousness of the situation, and they defined such bloodthirsty xenomorph creatures as desolate beasts, and declared a state of emergency, calling on all countries to unite and launch a counterattack against desolate beasts. ”

"Fortunately, the human society at that time had a sound crisis management mechanism, and after experiencing the initial panic, there were soon strategies to deal with the wild beasts, which were effective, and in the face of powerful scientific and technological means, the wild beasts had a large-scale death, and the casualties caused by the wild beasts to the human side were also decreasing day by day."

"This period is the first stage of the struggle between humans and beasts."

Jiang Mu asked, "The first stage?" ”

"Yes, the first phase lasted a total of three months from the appearance of primitive insects and beasts to the initial dominance of humans, during which a total of more than a billion people were killed......

Jiang Mu listened and nodded constantly. Three months, the death of more than a billion people, even after hundreds of years, still gives people a feeling as if it happened in front of their eyes.

Zong Zheng continued: "According to the ancestors, in the past three months, human society has completed the transformation to deal with the crisis and successfully curbed the spread of the desolate beasts, but with the increasing number of flying desolate beasts, this short-lived advantage is quickly lost again! ”

"There are more and more new species of beasts in the wilderness, and they are growing in size! At this time, the desolate beast was no longer dominated by insects at the beginning, and the newly emerged large flying desolate beasts instead fed on insects, and after a long time, the insect-like desolate beasts withdrew from the stage, and the desolate beasts completed the alternation of populations within the desolate beasts......"

After more than ten years of tug-of-war, the human combat object was replaced by the increasingly large size of the air beasts, they are as small as bats, large as eagles and falcons, the means of attack compared with the first stage of the beasts have been improved by leaps and bounds, and the momentum is more rapid and dangerous. From Zongzheng's account, Jiang Mu learned that this stage was called the second stage, and the humans and the desolate beasts were once again in a stalemate.

"However, although the second stage is dangerous and the range of human activities has been greatly restricted, human beings still have the means to deal with it, but with the emergence of the subsequent 'scaly beasts', the survival situation of human beings has completely changed."

"Scale-......"

After Jiang Mu heard this term, the first thing that flashed in his mind was the monster covered in black scale armor that he encountered when he first came to this world.

That ferocious monster is not easy to deal with at all, and secretly estimated that a scaly beast is roughly equivalent to an acquired level martial artist, coupled with its brutality and bloodthirstiness, it is estimated that even an acquired martial artist may not be able to take it down smoothly.

Before coming to Bize Canyon, Jiang Mu had already known from Ai Lin that the current Great Hung Star was no longer the world of scaly beasts, and now humans no longer dared to go out alone, and every time the settlement sent a team to hunt, or communicate with other settlements, it would always be accompanied by casualties.

The scaly beast is actually a general term, specifically referring to the beast that has evolved into a scale.

With the appearance of this kind of wild beast, the balance of combat power between humans and wild beasts has undergone a complete transformation.

Zong Zheng's eyes showed horror, and his long white beard began to tremble with his emotions: "From the appearance of the scaly desolate beast, it was announced that the flying desolate beast had officially withdrawn from the stage, and it was difficult for humans to be their opponents anymore, and the population suddenly dropped from more than 13 billion to less than 7 billion. ”

The next thing Jiang Mu was already able to imagine. On the one hand, the population has decreased, leading to a fault in science and technology, and the exploitation of resources has been seriously restricted, on the other hand, the huge gap in individual combat power has continuously compressed the living space of human beings, and human beings have inevitably entered a historical cycle of continuous decline.

Under the background of that time, the ancestors of the Great Star human race had no choice but to retreat and establish large and small settlements around the world.

Fortunately, although the human race was embarrassed at that time, the heritage still existed, and if you didn't want to go out and fight for the supremacy of this planet, there was no problem with self-preservation.

No matter how strong and big those scaly beasts were, they couldn't break through the defenses of the human settlements. Therefore, this strategic contraction has given mankind a little respite.

Of course, the price is not small, a corner of peace, giving up the status of the planet's hegemon, although maintaining the survival of the race, but limited resources also restrict the growth of the population, and it may really bid farewell to the center of the stage of history.

"A hundred years ago, the megalodon beast appeared, and the fragile balance was broken again, so that humans completely lost the ability to compete with the beast."

Seeing the puzzled expression on Jiang Mu's face, Zong Zheng shook his head and said, "The Megalodon Desolate Beast is different from the flying Desolate Beast and the Scaly Armor Desolate Beast that appeared before, if the first two are only a small change in the function of the body, then the Megalodon Desolate Beast is a subversion in the evolutionary field. ”

At this time, Rogge on the side couldn't help but speak, only to see him swallow his saliva, and said with palpitations: "The body size of the megalodon beasts is extremely huge, they are like flowing sand dunes, and they can no longer even be called 'beasts', if you have to use one word to describe them, maybe the word 'fortress' is more appropriate!" ”

Jiang Mu was still a little confused, from the mouths of Luo Ge and Zongzheng, he could know that the megalodon desolate beast should be a giant desolate beast, but is this kind of desolate beast really so terrifying? What does the word "giant tooth" mean?

Is it full of teeth?

Suppressing the doubts in his heart, Jiang Mu frowned and asked, "Since the size of the megalodon desolate beasts is extremely large, there shouldn't be many of them, right?" ”

From the perspective of the food chain, the larger the species, the more food it needs to consume, and the amount that nature can provide is limited, which in turn inhibits the size of the species.

So the larger the species, the smaller the population.
