“Genes complete the expression of biological characteristics by controlling the synthesis of proteins.”
"What color your hair is, how many eyes you have, and what gender you are are all determined by your genes."
The gymnasium of Yangcheng No. 2 Middle School was crowded with people, and military representatives stood on the stage and talked.
"In the human genome, there are 3.16 billion DNA base pairs."
"But the gene coding sequence that can produce proteins only accounts for 1.5% of the total length."
"The remaining 98.5% are restricted and cannot express themselves."
"If this part of the sequence is activated, the individual organism will express the characteristics of its ancestors."
"We call this phenomenon atavism."
…
This is the last class for all graduates in the third year of high school.
The huge gymnasium was packed with students.
Li Xiang was in the crowd, stretching his neck and looking longingly at the officers on the stage.
It has been almost a month since I traveled to this parallel world.
This world is a little different from before.
A hundred years ago, a major earthquake cracked the Antarctic ice sheet, and a strange energy body was released.
Subsequently, countless plants, animals, and insects mutated.
A large amount of land has been invaded by mutated plants, and ferocious beasts are rampant.
Humanity was forced to retreat into cities and build fortifications.
Those decades were called the Age of Catastrophe.
Later, people discovered that these ferocious beasts were not mutated, but were affected by the strange energy body and "degraded" to the state of their ancestors.
Human trials will follow.
Immediately afterwards, a returning warrior was thrown into the battlefield.
Turn things around.
Humanity, get a chance to breathe.
…
Yangcheng has a population of 300,000 and is a medium-sized city.
In order to resist the invasion of the atavistic beasts, the city defense army selects people over the age of 18 from the graduating class of high schools every year to undergo the atavistic test.
For these boys and girls, this is a huge challenge but also an opportunity.
Even if you fail to return to your ancestors, you can still be recruited into the city defense army and receive a high monthly salary and twice as many material supplies as ordinary citizens.
Of course, joining the city defense army also comes with huge risks, which are:
30% death rate.
Li Xiang was both nervous and excited.
He has died once and is not that afraid of death.
What's more, it's the yearning and yearning to become a return to one's ancestors.
For example, the legendary war god Yan, after returning to his ancestors five times, transformed into the fire god Zhurong, wielded nine heavenly fires, burned mountains and boiled seas, and destroyed countless ferocious beasts with just a few movements.
If you live your life again, even if you cannot shine like Yan in the Nine Provinces, you will never be able to live in a mediocre way and do nothing.
At this time.
A girl raised her hand and asked loudly: "Lieutenant Colonel Liu, are you an atavist?"
Lieutenant Colonel Liu smiled faintly, turned around, stretched out his right hand, and pressed it against the wall.
I don't see how hard he used it.
His right palm has sunk into the wall.
He took back his hand, and a palm print several centimeters deep was dented on the cement wall.
hiss.
Hundreds of graduates were stunned.
This is definitely not something normal humans can do.
Li Xiang's pupils shrank suddenly, and his heartbeat suddenly accelerated a few minutes.
Atavistic!
This Lieutenant Colonel Liu is actually an atavist!
Moreover, he is also a rare fighting type.
Li Xiang was extremely surprised.
You must know that every time you return to your ancestors, it is uncontrollable and unpredictable.
Poets, scholars, officials, knights, all kinds of identities are possible.
In this world, where human beings are huddled in cities, what they need most is atavists who have strong fighting power and can fight ferocious beasts.
Facing the students' horror, Lieutenant Colonel Liu just calmly patted the dust on his hands and continued:
"So far, there have been at most five recorded atavisms..."
"The first return to the ancestors, awakening the bloodline genes of the martial arts era."
"The second return to the ancestors, awakening the bloodline genes of the end of the Dharma era."
"The third return to the ancestors, awakening the bloodline genes from the age of cultivating immortals."
"The fourth return to the ancestors, awakening the bloodline genes of the age of immortals and gods."
"The fifth return to the ancestors, awakening the bloodline genes of the ancient times."
"And I only made the first return to my ancestors, and now I am at the sixth level."
The entire stadium exploded instantly.
"That's a cement wall. In Lieutenant Colonel Liu's hands, it's actually softer than tofu!"
"This is only the sixth level. If it reaches the ninth level, wouldn't it be possible to cut iron like clay?"
"Oh my God, it would be great if I could also become a warrior."
Just when the students were whispering to each other.
There was a huge sound, shaking the windows of the gymnasium and buzzing.
The students turned around and saw that in the sky not far away, there were three fighter jets flying past in a Z-shaped pattern, leaving three shallow trails in the gray sky.
A soldier trotted up to the podium and said something in Lieutenant Colonel Liu's ear.
Lieutenant Colonel Liu raised his hand to signal the students to be quiet.
"I just received news that a small wave of beasts is attacking the defense line in the northern defense area. It has been repelled. There is no need to worry."
Wait for the students to calm down.
Lieutenant Colonel Liu had a solemn expression:
"A hundred years ago, a major earthquake that spanned half the world ushered in an era of catastrophe."
"During the subsequent wave of atavism, humankind almost became extinct."
"Fortunately, some people who have returned to their ancestors have stepped forward, shouldered the heavy responsibility of inheriting civilization, and saved hundreds of millions of people from the fire and water."
"Generation after generation of ancestors have used their flesh and blood to fight against ferocious beasts and protect their compatriots."
"Now, it's your turn!"
This moment.
In the gymnasium, you can hear a pin drop.
Lieutenant Colonel Liu's eyes swept over the faces of hundreds of young boys and girls.
There was no fear or flinch in those eyes.
Only perseverance and bloodiness.
Lieutenant Colonel Liu shouted:
"He who is the only son in the family, stand up!"
As soon as he finished speaking, hundreds of students stood up.
"Those whose parents are in the city defense army, stand up!"
"Brothers and sisters who are in the city defense army, stand up!"
"Those with disabilities, stand up!"
"..."
"You who are timid stand up!"
No one stood up again.
"Anyone who stands up, please leave. Yangcheng does not need your protection for the time being."
The boys and girls who stood up were all dejected.
After a while, there were only more than 300 people left in the gymnasium.
One by one, they held their chests high and their morale high.
Li Xiang sat in the crowd, nervous and excited.
Click click click.
The door and the special windows were suddenly closed.
Two soldiers, wearing protective clothing, pushed a huge alloy tank and came to Lieutenant Colonel Liu.
Lieutenant Colonel Liu looked around at everyone, his sharp eyes seeming to be real.
"Everyone, next, you will usher in your first return to your ancestors."
"The process will be very painful."
"Some people may even be unable to withstand the impact of returning to their ancestors and die."
"But if you want to wear a crown, you have to bear its weight."
"Everyone, I wish you good luck."
After saying this.
Lieutenant Colonel Liu put on a protective mask and pressed the switch on the alloy tank.
Click.
The red gas spread quickly, and soon the entire stadium was shrouded in red mist.
The surroundings suddenly became quiet.
There was just the hiss of red mist as it was released from the alloy tank.
This fog is getting thicker and thicker.
Li Xiang's line of sight was blocked, and even the classmates sitting next to him couldn't see.
I don’t know if it’s the red mist, or if it’s because I’m too nervous and excited.
He only felt that his heartbeat was getting faster and faster.
It seemed like it was about to pop out of my throat.
