317 inaccessible mossy ice fields, karst landscapes forge a huge underground world.

The few kerosene lamps spread the warmth of the vast space, and the metal and ore on the roof of the cave and the stone walls of the cave reflect a faint sheen.

Damp, cold, silent, oppressive.

In this underground space that is inaccessible to people and even like another world, the thick steel pillars of the arm connecting the ground and the roof of the cave firmly surround a square iron prison of hundreds of square meters.

On the only door of the iron prison, a heavy, rusty lock was firmly fastened.

It's a secluded place, a place where you don't see the sun all year round, and you can't even breathe fresh air.

The cold underground moisture can constantly erode and engulf anyone's heart.

But in the iron prison, dozens of thin figures curled up in various directions of the iron prison, some were lying, some were sitting with their legs in their arms, and some were pounced on the steel pillars of the iron prison.

It was a group of boys and girls who looked to be no more than ten years old, wearing thin gray short-sleeved shorts on the outside of their thin bodies.

There was no food, and the only thing they could survive was the occasional dripping of groundwater from the stalactites on the roof of the cave.

After many days of hunger and cold, most of the children were already crumbling.

What's even more terrifying is the hollow and silent atmosphere of the underground world, but the dark and mysterious atmosphere, even if adults stay for a long time, they will feel oppressed and uneasy in the isolated space, and even more in the cold iron prison, despair is constantly breeding.

Two days ago, there were still children who couldn't bear the fear in their hearts and cried, but the children who had spent a lot of energy because of crying and wailing, by this time, all of them had run out of oil early.

Among the dozens of children, most of them were already cold children's corpses, but because of the extremely low temperature underground, the corpses decomposed extremely slowly, and they were only in a state of ossification.

Being in the ground without the sun, moon and stars, I don't know how many days have passed.

Gradually, the remaining dozen or so children became the last chance of life.

In the huge iron prison, no one spoke, and everyone's breathing became extremely quiet, because they knew that if they wanted to live, they could not waste any energy.

At this time, a slightly older child, after enduring unimaginable hunger, finally had a move.

In the most energy-efficient position, he slowly moved to the side of the corpse of one of the children closest to him.

In the darkness, the boy leaned down, opened his mouth, and bit down slowly and firmly from the neck of the child's corpse, which was about the size of himself!

In a short time, the sound of teeth biting and chewing raw meat came from the silent iron prison......

It is not surprising that this kind of sound, which ordinary people will never hear in their lifetime, seems so sparse and ordinary to the ears of the remaining dozen children.

As the first child foraged for food, among the remaining children, three more children gradually appeared looking for corpses and gnawing them.

The children's teeth were sharper than expected, and when they swallowed stiff raw meat, they were silent, and some were just "snorting" heavy breathing.

With a few mouthfuls of flesh and blood, the child gradually gained strength, and the sound of biting became louder......

In one of the corners of the iron prison, another boy couldn't help himself, moved his limbs, and crawled to the two corpses closest to him.

Two corpses, a girl and a boy, lay on the ground, there has been no movement for more than a day, the girl's body is extremely thin, but at such a time, there is no difference between boys and girls, some are just food!

The boy didn't choose much, just swallowed his already bitter saliva, opened his mouth, and made a gesture to bite down on the girl's corpse......

Suddenly! The boy felt something strange!

However, the moment when it feels wrong, it's too late!

The "corpse" of the girl, who had been thought to be dead, suddenly turned around, and a palm as thin as white bones slapped angrily near the boy's temple.

The girl's fingers had long nails, and with all her strength at the moment, the nails sank into the boy's head......

The original "eater" became the "prey" of death in the blink of an eye.

The girl rolled over and threw herself on the boy's freshly dead body, like a mad, hungry lioness cub, and began to bite at the boy's flesh......

The corpse that has just died, after all, still has body temperature, and the blood is also warm, such "food" can obviously allow the "predator" to obtain greater survival costs.

A few tens of seconds after the girl began to eat her first meal in many days, the "boy's corpse" who was closest to the girl also sat up slowly.

The boy, silently, approached the body of the girl who had just been stabbed to death, and without any communication with the girl, opened his mouth, and bit down casually where the girl had not bitten or where it was......

The girl didn't seem surprised, apparently knowing that the boy was also faked to death, waiting for the rabbit, waiting for the warm prey, biting and drinking the blood.

After all, it is extremely difficult to bite raw meat, even if it is mostly swallowed, boys and girls eat it for almost an hour before they stop eating with blood on their faces.

The corpse, which had just been warm, was already emitting a foul smell.

It's just that because there are corpses that have been torn and bitten everywhere in the entire iron prison, the stench has already permeated.

The two sat back in the corner of the iron prison, and in the darkness, the two could only vaguely see each other's vague faces, the same unkempt hair, but in the eyes of the two, they exuded a vigilant gaze like a beast.

Both children know that the other is the best at surviving in this kind of survival training, as long as they give each other any gap, the other party's next prey will be themselves.

It is obviously unwise to fight such an opponent when it is not necessary, so defense is the best option.

As they sat down, their eyes never took their eyes off each other's faces......

I don't know how long it took, when a beam of light came through the door of the iron prison and searched the two of them, the two of them slowly turned their heads to the dazzling light.

A pale, indifferent voice recorded the results of the training in Russian......

"Fifty-seven test subjects, two survived, number thirteen, number seventeen ......"

……

In a dense pristine rainforest, a colorful venomous snake entangles a towering redwood.

On the sunny side of this redwood, a teenager wearing tight camouflage short sleeves and canvas camouflage pants underneath, with a slightly immature face full of dirt, looked thirteen or fourteen years old, with a sturdy and strong body, sitting on a soft pile of fallen leaves with his back against the redwood tree.

In his hand was a Sen Han short-bladed saber with a blood groove, and the saber was stained with blood stains, but it had not yet dried.

The chirping of cicadas resounded in the rainforest, and the boy seemed to be asleep, his eyes closed and his head tilted.

At this moment, a figure also wearing camouflage short sleeves slowly walked out of a pile of banana leaves, holding a short blade in his hand, and approached the young man.

When he walked a foot in front of the young man, the saber in the young man's hand suddenly pointed at the approaching figure, and the young man's eyes were already open.

It was a pair of cold and numb eyes, but the cavity seemed to hide surging lava.

"It's ...... you"

The boy spoke lightly in English, but he knew the figure that appeared in front of him.

Walking in front of him was a girl who was also thirteen or fourteen years old, with short hair and ears, snow-white complexion, because of the long-term sun exposure to light red, a face could already be seen to be quite exquisite, if time, it must be a beauty who turned all beings upside down, but it was like the cold look of the cold winter of the wax moon, and the same numbness and tenacity in the eyes as the teenager, but it was difficult for people to give birth to half a trace of intimacy, and even as long as they looked at it, it made people retreat.

"I'm going to work with you", the girl said bluntly without turning around at all.

"Why," the boy asked.

"You are the strongest of all, I want to live, and I have the highest success rate with you", the girl said succinctly.

The boy scoffed, "You should know that the enemy is not only poisonous snakes, fierce beasts, but also anyone in the rainforest. ”

"Are you afraid of me?" the girl smirked disdainfully.

"Don't provoke me childishly, take out your capital", the teenager sneered.

The girl suddenly showed a charming smile that did not match her age at all, and a pair of moist eyes exuded a strong feminine enchantment.

"There are already two stupid men who think they can eat me, but I kill them, you are better than them, but there is one thing you are like them......"

The girl paused, had an extremely seductive hoarse tone, and said: "You are also a man, you are like them, you want women, you want to vent ......"

The young man's eyes were slightly strange, and he was silent for a long time, "You are not the only woman here." ”

"That's right," a smug look appeared on the girl's lips, "but you know very well that I am the most beautiful of them all." ”

After the girl finished speaking, her posture gracefully began to fade the tight short sleeves on her body, and gradually began from the delicate and tight waist, revealing the fair and attractive skin on her body......

The girl is obviously professionally trained, and every movement is extremely seductive, and it is difficult for anyone to imagine that this is a thirteen or fourteen-year-old girl's action!

When the young girl's young body was still in the development stage, it was completely presented in front of the young man, and the young man's eyes were finally no longer calm, and the fire was ignited.

"I want to live, you have to live too, as a weak person, I exchange my body for your assistance", the girl did not show off any women's weapons anymore, stood in front of the young man with her whole body exposed, and asked solemnly: "Thirteen, do you dare to ask me?"

"How can I trust you", the young man was obviously suppressing something, he had already understood the relationship between men and women, the madness that had been suppressed for a long time, he really needed a venting channel to prevent himself from collapsing due to the huge load on his brain, but he also knew very well that the owner of the body in front of him was a poisonous scorpion that had always been beautiful......

The girl bit her thin lip, her eyes were so resolute and cold, and she said clearly: "I don't have any evidence, but I can tell you - this is my first time."

The boy didn't ask any more questions, and a leopard-like lunge threw the girl's body to the ground......

After a storm, calm returned to the pile of dead leaves.

"What's your name......"

"Seventeen. ”

"Your original name ......"

"I don't know. ”

"Why do you want to live so persistently, and when you die, it's actually liberation......"

"I want to go back to my hometown, I want to see my parents".

"Why ......"

"I'm going to ask them, my name ......"
