It's night, and the moon and stars are scarce.

There is a park in Kabara Castle where a man and a woman are jogging on the trail.

The boy looked older, about fifteen years old, while the girl was younger, about thirteen years old.

"Whew-"

Exhaled lightly, Qiu Chen's forehead was already covered with fine beads of sweat.

He has short black hair, and he looks ordinary, but his eyes show a look of determination.

"There's still a kilometer to go." Qiu Chen opened his mouth and looked at the crowd in the park at the same time.

It is his habit to insist on running long distances every day, and of course, this is the behavior advocated by the government today.

It's the year 2067 A.D., and the world hasn't ushered in any World War III as imagined and returned to primitive society, but the status quo is not much better.

On October 15, 2017, a meteor shower suddenly hit the earth, although the earth did not have a major earthquake because of the meteor shower, a tsunami and other disasters, but this meteor shower brought unprecedented drastic changes to the earth.

Explosion of Endogenous Organisms!

In 2019 AD, a strange creature appeared in the world, they are like zombies in the fantasy of human beings, they are extremely infectious, but one by one they are extremely powerful, even if the country has a strong military force, but it cannot completely eliminate it.

Disaster was born.

Up to now, human society has lost three-fifths of its territory, and only a few dozen of the original 199 countries remain.

In order to survive, humanity has to start paying attention to physical fitness again, just to escape faster in times of crisis.

Of course, how much it can do is another story.

"That's all there is left?" Hearing this, Qiu Lan blinked her eyes and said, "Brother, do you want to run more?" ”

Qiu Lan's physical strength has always been very good, and this distance is not enough for her to reach her limit.

"Run a little more?" Qiu Chen shook his head, then looked up at the bright moon hanging high, and said, "It's late now, and it's ......"

He couldn't help but feel a little helpless: "My physical strength can't last long, and I'll have to walk home later." ”

The brother and sister's home is in a safe community one kilometer away, although there is a bus, but the two are reluctant to spend money to take the bus to walk such a distance.

Although electricity is the main energy source in this era, it is no longer generally expensive.

Even with it, the fares of various means of transportation have also increased a lot.

"Oh-" As if she had been hit, Qiu Lan was a little dissatisfied and elongated her voice.

"Huh! Isn't this the Qiu family brother and sister? ”

At this moment, a middle-aged uncle who was practicing Tai Chi found the brother and sister running from a distance, and he greeted him warmly: "I heard that you have all found out that you have the adaptability of the 'source cell vaccine', congratulations!" I really envy your mother...... If only my boy had adaptability. ”

"Hello Uncle Li."

Qiu Chen's brothers and sisters naturally discovered this middle-aged man, this middle-aged man Qiu Chen is very familiar with, he is the neighbor of the Qiu family, called Li Ming.

"It's just luck." Hearing this, Qiu Chen smiled, although he was excited in his heart, he didn't have much smugness.

In this era, there are all kinds of endogenous organisms all over the world, and their body fluids are extremely infectious, once they are infected, then the DNA of the organism will be rewritten, and the life form will change greatly, and many normal creatures will become crazy because the changes are too drastic.

Source cell vaccines are developed to deal with these derived organisms.

Normally, humans have a huge advantage over other creatures, even if the rat becomes comparable to an elephant, humans can't kill it, but there are not some particularly dangerous individuals in the source creatures.

Source Force!

This is the power of sourced organisms.

In other words, this is a transcendent power like immortal power, magic power, and internal force.

Derived creatures with source power have defense power even higher than steel, and their speed can break through the speed of sound, and their body size has become incredibly large to tens or hundreds of meters.

All this is the real reason for the defeat of mankind.

If humans who just get bigger or something are not afraid at all, what they are afraid of is that they have become mythical creatures of fantasy one by one.

Today, more than 90% of the living things on the earth have been transformed into natural organisms, and there are all kinds of strange and strange creatures outside the cities where humans live.

Humans who have been vaccinated with the source cell vaccine have the ability to come into contact with the source of organisms head-on, and they are able to grasp the magical power of the source force.

Source Force Warriors!

This is the new branch of the military, and it is also the trump card of human beings against endogenous creatures.

"This luck is indeed enviable." Uncle Li smiled, then turned his head and swept away the crowd exercising in the park, and said: "The government has been promoting the F-type source cell vaccine for decades, but there are still a few people who can adapt to the source cell vaccine......

In the end, Uncle Li couldn't help but sigh.

Although I don't want to admit it, he is probably one of the most people.

In this era, it is becoming more and more difficult for ordinary humans to survive.

Regardless of the fact that there are parks and other things in the city, entertainment is no longer an important part of people's lives.

"This ......" Qiu Chen couldn't help but shake his head gently.

Right!

It is rumored that 50 years ago, there were more than 160 cities with a population of more than 1 million, but now there are only about 70 left, and the population density is exploding.

Moreover, these cities are slowly disappearing at a rate of one year at a rate, and if this trend continues, it will only take decades for humanity to extend.

Thinking about it like this, Qiu Chen's heart couldn't help but feel a sense of urgency.

You have to gain the power to protect yourself!

Only in this way can he let his family live happily.

"Hmm! ——”

And at this moment, fifty meters away in a square, a man in a blue shirt in his forties shook his body with a pale face, and suddenly, suddenly felt a wave of nausea and wanted to vomit.

For a moment, he was half-kneeling on the ground and covering his mouth at the same time.

"Lao Wang? What's wrong with you? ”

A man who appeared to be an acquaintance of his walked over.

…………

At the same time, a kilometer away on a street.

A young woman in a blue trench coat drives a bizarre black and red motorcycle, and in the back seat sits a young man also wearing a blue trench coat with a small blue and white shield on his arm.

Dididi——

Suddenly, an instrument on the motorcycle suddenly sounded, and at the same time quickly switched to the radar screen, and a red dot kept flashing.

"It's ......"

Hearing this voice, both of them were startled at the same time.

"That direction...... It's the interior of the city! There will be a source of life! The young man glanced at the instrument behind him, and at the same time looked down at the woman in front of him, and asked, "Captain, what should I do?" Are we going to continue our mission? ”

"Let's go!"

Hearing this, a solemn look appeared on the woman's face, and then she accelerated suddenly.

Airplanes!

The motorcycle made a beautiful turn at the intersection and sped in the direction of the red dot.
