Two tusks can easily pierce into the neck of the prey, instantly killing him.

The female's mouth is not even about to degenerate completely, and the male is also degenerating, and since the brain began to develop and evolve, they are becoming more and more intelligent, they no longer seem to be as fierce as the ancestors.

From its birth to the age of 13.357 million years later, this species learned to make tools, and tribal civilization was born, thus embarking on the journey of conquering the earth.

After 33,63 million years later, about 680 million years ago, this species entered the nuclear civilization era, creating a more brilliant amphibious civilization on Earth than humans, with their cities on land and their cities in the water.

With the progress of civilization, they began to run to the sea of stars, the moon, Mars, they found amethyst in the Koiper belt, but the formation of amethysts even if they have not yet studied, but does not prevent the later later became a typical mark of this civilization.

This civilization dominated the earth for more than 130 million years, they spent the most dangerous period of time, and even into the level of stellar civilization, this civilization has been able to easily resolve the threat from the universe, especially the threat of asteroid impact on the earth, in the most glorious moment of its civilization, an asteroid 30 kilometers in diameter hit the earth, but was successfully resolved before the asteroid hit the earth.

However, even though their civilization has flourished so powerfully that humanity today is beyond the reach of a planetary civilization, there is still power that they cannot resist.

When Ren Hong saw it here, he found that in the star area around the solar system, there was a star that disappeared more than 600 million years ago.

More than 600 million years ago, the era of prehistoric civilization, there were 12 stars in the universe 11 light-years away from the solar system, but only 11 stars exist today, they are four single-star systems: "Banard Star", "Furf 359 Star", "Ross 154 star" and "Leyland 21185 star"; two double star systems: "Sirius A", "Sirius b" and "Ludayton 726-8a", "Ludayton 726-8b"; a three-star system: "Half α"

More than 600 million years ago, there was a fifth single-star system in the universe, 11.7 light-years from the solar system.The star was born 2.55 billion years ago, when the species did not exist on Earth.At that time, the star was ten times brighter in Earth’s night sky, showing a pale blue color in the night sky.

From its birth, the star is unknown but burned in glory for nearly 700 million years, although the star with a "constant" word, but it does not exist forever, the star also has a life, and the size of the star is 53 times that of the sun, its life is destined to be no more than 1 billion years.

In fact, 700 million years of time finally to burn out its life, undertake the fusion fuel of the hydrogen elements less and less, the formation of helium by the star gravity to the center of the deposition, more and more helium material gathered in the center, the remaining hydrogen elements are still in fusion, like the last breath of life.

Finally, helium also has a fusion reaction, but the energy generated by helium fusion is far less than the hydrogen fusion reaction, and the star's gravity continues to shrink, and the rising temperature is almost never-ending.

The beginning of helium burning means that light elements will come together to transform into heavy elements, which means that the star will eventually only explode.

And the intelligent civilization of this period of upright and glorious time on Earth found this star in its late age.

The luck that lasted more than 130 million years is finally coming to an end.

The distance to the solar system is only 11.7 light-years, and its death will affect the entire solar system and the space of more than a dozen stars around it.

And the civilization on Earth can not stop, when the star explodes will mean death, extinction.This civilization is accompanied by a crisis of genocide at its most glorious moments.

They know that the star has entered its old age, burned for 700 million years, and may explode at any time, maybe tomorrow, maybe a hundred years from now, maybe ten thousand years later, maybe even 11 years ago, or even 11 years ago, it may be possible to explode, and it takes 11 years to return to Earth from there, and it is 11 years ago.

They were able to stop the asteroid from threatening their home, but the fire in the face of the star was powerless, and he could explode at any moment.

The only hope to survive is to leave your home and leave the solar system.

However, even in the heyday of the times, this civilization is still unable to get away from the solar system, they have just entered the star civilization, the largest activity area is limited to the solar system, without breaking through the velocity constraints, it can never enter the galaxy civilization stage, the speed limits them.

But they did not sit still, in order to save the future from destruction, they decided to leave their home to drift and wander into the unknown deep space of the universe.Then they poured the financial and material resources of the entire civilization to build a space station and take the excellent population people away from the solar system.But more people waiting for their fate has only one outcome, limited time can not move the entire civilization out of the solar system, in order to deal with the stars that may explode at any time, their space station did not have time to build too large, all for the continuation of the population, can leave quickly, never look back, because the speed is not faster than the speed of light, only time to make up.

In this way, 68 years have passed again, and over the years they have been fleeing beyond the solar system to continue the fire of the population.

In the 55th year of the great race escape, the star at 11.7 light-years away finally came to the end of life, and the gravitational force generated by the massive body of the star produced a repulsive counter-offensive phenomenon, the density of the core was unimaginable, and the material of the core was as high as billions of tons.

The dense core finally broke through the limits of the tipping point and collapsed, and the entire star collapsed from the inside out.

At the moment when the star exploded, the entire universe seemed to be torn apart, and in the last moment, it ended 700 million years of life in the most vigorous form, and the unfathomable and dense mass of debris, endless dust, almost infinity of energy electromagnetic pulses, high-energy particle streams, sub-radiation floods and other deadly matter rushed to every corner of the universe at the speed of light.

This accumulation of 700 million years of "anger" is also towards the solar system 11.7 light-years away, 11.7 years later will reach the solar system, whether it is Earth, Mars, Jupiter, Saturn, the entire solar system will not be able to avoid the accumulation of 700 million years of "anger" impact, for the activity in the solar system life, this is irresistible, desperate, destructive.
