In 2888 A.D., the Milky Way Galaxy, the Alliance of Mankind!

Praying mantis constellation, an inconspicuous small constellation in the Milky Way galaxy, the praying mantis constellation is very close to the sun constellation, in the late Xiuzhen era, the scientific and technological civilization and the Xiuzhen civilization are fully integrated, the praying mantis constellation is the first constellation to be discovered after human beings stepped out of the solar galaxy,

The abundant resources contained on the hundreds of planets of the Praying Mantis constellation are the second step in the rise of the Human Alliance! It is of great significance to the later era of national cultivation and the current era of conquest!

The Praying Mantis Constellation has been discovered by the Human Alliance for nearly two hundred years, and it has been more than a hundred years ago, when the Human Alliance has not officially announced that it has entered the era of conquest, the Praying Mantis Constellation has become an important immigration point for the Human Alliance.

Today's praying mantis constellation has reached eighteen planets of large-scale human migration, and the total number of immigrants has reached 30 billion!

Eight hundred years ago, this was simply unimaginable, going out of the solar system and immigrating to alien planets, this is simply a fantasy, but in the current era of interstellar conquest, this kind of thing is simply commonplace!

In the eighty years of the war era, the tentacles of the human alliance have already extended to the entire galaxy, and even the extragalactic galaxy is involved, such as the small constellation of the praying mantis, among the forces of the human alliance today, there are already tens of thousands, and even more than 100 large immigration constellations with a population of more than 100 billion!

Humans are no longer the humans they were!

The praying mantis constellation buries a kind of mantis gold, and the praying mantis constellation is also named after it, this kind of mantis gold is very tense, and it is an important auxiliary metal that can be equipped with interstellar warships and spirits, and the praying mantis constellation is sub-focused on the human alliance because of this auxiliary mantis gold, but the production of this metal is very small, fifty years ago, the mantis gold of the praying mantis constellation has been exhausted, and then it was developed into a human immigration constellation!

One of the eighteen immigrant stars of the Praying Mantis constellation - the Knife Mantis Star!

The Sword Mantis Star is much larger than the original human home planet, the Earth, with a population of one billion immigrants, and a land-sea distribution ratio of five to five, with five continents and five seas!

Orange Island, one of the five continents of the Knife Mantis Star, has the smallest area among the five continents of the Knife Mantis Star, but the territory area also reaches 30 million square kilometers, with a population of 220 million, logically speaking, this is a super vast and sparsely populated place, but in fact, it is not the case, not only is it not sparsely populated, it can even be said to be super crowded!

Because on the vast territory of 30 million square kilometers of Orange Island, the place that is really suitable for human survival is actually very small!

Since the development of human beings, aside from the Dark Age and the Wandering Era, after the three eras of the Age of Recovery, the Era of Cultivation, and the Era of Conquest, the development of life science and technology has already exceeded imagination, and the power of Cultivation has further extended the life span of human beings.

But food, oxygen, and water are still the three basic substances that human beings cannot live without, of course, this is the cultivation of true power has not yet reached a certain level, the environment of the Knife Mantis Star is extremely harsh, there is no oxygen and water in many places at all, and there are even many strange alien life!

Longyang Province, located at the head of Orange Island, one of the ten provinces of Orange Island! Yecheng, one of the eighteen cities under the jurisdiction of Longyang Province, a curved stream surrounds Yecheng, and it is precisely because of this Yexi that Yecheng was established!

The huge steel city wall is fifty meters high and ten meters thick, all of which are mixed and poured with the strongest rock on the Sword Mantis Star, and its defensive power is amazing, it can withstand the blow of a ninth-level star beast, the steel city wall is like a dragon, the body is surrounded by an oval, and all eighty square kilometers of land are surrounded by the steel city wall, this is Ye City!

A huge building covering an area of 60,000 acres stands in the center of Yecheng in the center of the city, where the core of Yecheng is Yecheng College!

Eight hundred years later, today's academy is no longer the academy of 800 years ago, and it is no longer about imparting literature, physics, and other knowledge! It is about imparting the most needed techniques in the era of conquest, such as cultivating true knowledge, the mysteries of the universe, and analyzing the universe!

In the tenth class of the North District College of Yecheng College, a sphere on a ten-zhang pillar in the playground is red and dazzling, like a small sun, controlling the temperature of this area at 60 degrees.

"Persistence, all for Lao Tzu to persevere, this temperature can't bear it, and I want to step into the road of cultivation, and hold on for another ten seconds, ten, nine..." In front of hundreds of teenagers and girls, a coach with a serious expression shouted: "Three, two, one! Okay, change the air conditioner! Hold on for another ten minutes!"

The ball of light on the pillar turned white, and the cold air instantly emanated from the sphere, enveloping this area, and the temperature on the playground dropped rapidly in a moment, from 60 degrees to minus 20 degrees in less than a minute! Such a drastic temperature change suddenly made these hundred teenagers and girls unable to hold on, and a faint white smoke came out of the skin of every teenager, and the beads of sweat were condensed into ice beans in an instant!

Coach Yu Qiang said in a deep voice: "Hold on, this is only 80 degrees of temperature change, you can't hold on, you must know that the casual temperature change in the universe is more than hundreds of degrees, or even thousands of degrees!

These hundred teenagers and girls are all sixteen or seventeen years old, although they are all frozen and trembling, but all of them are strong to keep their bodies balanced, among these teenagers and girls, there is a thin teenager standing in the last row, the young man's face is three points handsome, but unfortunately in this era, you can't eat with your face, today's human alliance, advocating martial arts, no strength, no right to speak!

The young man's body kept trembling, his lips were already frozen and blue, and there was a thin layer of frost on his hair and eyebrows, the young man bit his lips, but his hands were a little drooping, these two ten-pound barbells were heavier than a thousand catties at the moment, and the young man was simply unable to support it, and the strong alternation of hot and cold made Zhang Yang unable to bear it at all!

Syllable!

The barbell in Zhang Yang's left hand was the first to fall, and then the barbell in his right hand also fell, Zhang Yang's body shook violently, the strong cold made his eyelids heavier and heavier, and his thinking became slower and slower, and finally Zhang Yang's eyes were dark, and he fainted completely!
