After passing through the last deep mountain and jungle, the outline of the Z city base appeared in the eyes of Yin Yiliu and Jin Yang.

From the shade of the trees, she could see the towering outline of the base a little while stepping on her feet. The city wall outside Z City was first covered with special metal and potion to stabilize the wall and remove the beasts, and a layer was tied outside the city. The sturdy shackles that protrude outward are like a cold steel city.

But it is such a town that is condensed with high-level human wisdom. At this time, the walls outside the town were also smashed by unknown objects, and a piece of it fell crookedly to the ground.

The gate that had been wide open in the past was also tightly closed at this time, and only a small opening was opened under the gate. Those who came in and out were all evolved people, and they had to be illuminated by infrared sensory instruments.

The wasteland era that has been slack forward for three years seems to have regressed back to the moment of the end of the world in a few days, full of vigilance and fear of the outside world, and wrapped himself in a thick and heavy armor.

But Yin Yiliu knew that this was helpless.

After the darkeners broke out across the board, at least 40% to 60% of aliens turned into monsters opposed to humans overnight. They would occupy humanity, devour human consciousness, and become ugly and terrifying in appearance. Alien creatures.

Under such circumstances, the human beings living in the base civilization can only build high walls and keep the danger out, so as to protect the spread of human civilization.

The mutant leopard who followed all the way behind her was now silently tearing the wound on the sole of her foot, arching back and forth on the ground.

The nails are full of rust and bacteria. Even if the mutant beast has strong resistance and recovery capabilities, the little guy in front of him is only a cub. His eyes will be tearful because of his **** claws, and he looks at the mark in pity. Recalling Liu.

Yin Yiliu was softened by the damp beast pupil's look, and took out the disinfectant water and gauze from the space to wrap its big claws into two "buns."

It noticed that Yin Yiliu turned his head, pulled the gauze teeth on the soles of his feet, and suddenly paused. He raised his head and looked at the woman walking towards him with a very good expression.

Yin Yiliu knelt down, rubbed the furry head of the little beast with his palm, and said warmly: "It's enough here. Two kilometers ahead is the deep mountains and jungles. Set you free."

The deep mountains and jungles will always be so deep and peaceful. There are countless lives that have developed and prospered after the end of the world. The little beast is a member of the jungle. Only there can it be freedom in the true sense.

The soft touch of the fur under her palm reminded her of the feeling of lying on Xiao Hei when she was in the courtyard house. That arrogant black wolf was like this, with her shiny and smooth fur, which made her feel like letting go.

She missed the time a little bit, and she sighed in her heart and she didn't know how the young beast was so majestic now.

She knew that something like gauze was uncomfortable for mutant beasts, and after she was sure that the soles of the mutant leopard's feet had begun to grow glued, she gently pulled it off, and rubbed the little guy's head again, indicating that it was moving towards the mountains Away from the depths of the jungle.

"Go ahead."

Now is the time when the atmosphere of humans, mutant creatures, and darkeners are in a stalemate, and rashly bringing a small beast into the city will definitely attract the attention of interested people. Moreover, for this wild leopard, the jungle with abundant species is the most suitable for it. The place.

Although the mutated leopard does not have human-like intelligence, it is very smart and can roughly understand the kindness or maliciousness of human beings. For a leopard who has been raised on a human base as a driving beast since childhood, the longing for nature and freedom is deep in its bones. s things.

Even if it likes Yin Yiliu very much, it does not mean that it is willing to return to human society, to the hut that brought it humiliation and bondage.

It made two faint whimpers in its throat, rubbing its furry head against Yin Yiliu's palm, keeping it warm for several minutes.

Until Jin Yang turned his head slightly impatiently and frowned under the translucent mask, a little guy humming beside Yin Yiliu keenly noticed that this terrifying man gradually had A dangerous aura, so it turned its head in three steps and looked back at the same time as it walked toward the deep mountains and jungles.

After the mutant little beast gradually disappeared from Yin Yiliu's eyes, she and Jin Yang walked towards the z city base step by step.

When he could see the doorway outside the small door, Yin Yiliu suddenly stopped and looked towards Jin Yang beside him.

Jin Yang seemed to know what she was thinking, and the lips exposed under the mask made a faint arc toward her, as if calmingly said: "Go in."

He knew what Tutu was hesitating because of himself, because he didn't like it here, because Tutu took him to heart.

This clear cognition was undoubtedly revealed in Yin Yiliu's eyes, which made Jin Yang's heart warm.

Although Yin Yiliu could not see his face clearly, she could still imagine what a man would look like when he laughed, and her heart suddenly choked.

Jin Yang, as he did countless times before, he stretched out his palm as if he was treating a small milk bun that had only reached his leg. He rubbed the print of Yiliu's head with his palm and said softly, "Don't worry. I'm fine."

Yin Yiliu tilted her head, covering up her uncontrollable smile, "Yeah."

The figures of the two had just appeared within the searchable range of City Z, and the recorder who was monitoring the communications on the city wall caught them. Looking at the familiar man and woman on the screen, he stared slightly and "rubbed". Get up from the chair suddenly.

The companions around him were suspicious, "How come you were so surprised that you saw a mutant beast?"

The man didn’t speak. You must know that the person here is more heart-stirring than the mutant beast. He was fortunate enough to be on the same team with these two in a previous rescue activity. Under their leadership, the mission was clearly dangerous and easy. To resolve.

Since then, he has deeply remembered these two people. It was Jin Yang and Yin Yiliu who announced their departure from Z City a few months ago.

He took out the communicator in his arms and reported to it.

In just a few minutes, a white afterimage quickly passed on the block of the city base. The pedestrians passing by on the street saw only a very fast white light, with huge wings stirring the wind, and the body was like a fish swimming in the base. Flying low over the sky.

An evolutionary man who had just walked out of the shop and was still picking his teeth looked at the swiftly passing figure in the sky, immediately stood up, raised his chin and said, "Isn't that the little girl the captain is chasing? Where are you going to be busy?"

All of them were wearing extremely defensive protective gear and sophisticated weapons. The armor on their backs was printed with a scorching red lotus, and their identity signs were very obvious on the street.

The people around shrugged, "Who knows."

At this time, Yin Yiliu and Jin Yang were stuck before entering the small gate of Z City, and the researchers wearing isolation masks said coldly; “First take off the things on their faces, and then walk over from the infrared test. Entrainment is not allowed..."

As he was talking, there was a small figure hovering and whistling above the city gate. That person had a pair of huge wings, carrying the golden sunlight on her back, and could not see her figure clearly.

Yin Yiliu’s long hair in front of her forehead was a little messy, her apricot eyes were stabbed by the sun and she couldn’t open her eyes. She covered her eyes with her armored arms, squinting at the girl who was falling in the sky, her face couldn’t bear it. Live with a smile.

At the moment of landing, the huge wings behind Xiaoxiao suddenly gathered behind her, and her long tail tip swept on the ground as she eagerly moved forward.

Her eyes were already red, and she rushed into Yin Yiliu's arms, tightly wrapped her arms around the woman's neck, and suddenly staggered Yin Yiliu's body back.

"You are too cruel, you haven't sent us a message after walking for so long!"

Looking at the poor girl in front of her, Yin Yiliu couldn't help but touch the tip of her nose.

In front of Jin Yang, she didn't need to worry about anything, because there was always someone who would support herself behind her and let herself go and fight.

Whenever you look back, the golden thighs are always behind him and are the strongest backing.

But once she returned to City Z and was with this group of partners, she would always hide something unconsciously, trying to be a team leader as best as possible, taking care of the teammates who trusted her and becoming the backing of the teammates.

Xiaoxiao's arrival brought Li Zhenjiang's handwritten permit. After confirming the lord's manuscript, the inspecting researchers turned on the infrared of the base to let Yin Yiliu and Jin Yang enter.

The overall atmosphere of the Z city base is the same as when it left, and the chaos and barrenness of the small bases outside can not be seen. Everything is operating in an orderly manner, whether it is the base or the people in the base.

But at the same time, some things are quietly changing.

Xiaoxiao’s status in the base is special. Most people have seen her and know that this young girl is the lord’s confidant, but Yin Yiliu and Jin Yang beside her are strangers, most of the people in the base. I have only heard of the name of the "Depraved Killers", but I don't know what they look like.

In a narrow alley around the corner, Yin Yiliu and a male evolutionary passed by.

The man reacted very strongly, as if a current spread through his whole body from the point of contact, hiding far away in the opposite direction from several people, and looking at Yin Yiliu and Jin Yang vaguely and vigilantly.

All of this is because a large number of alien teammates suddenly become darkeners, and they are chatting and laughing with their teammates around them in the last second, and in the next second they will mutate and tear their teammates' throats with sharp teeth.

No one can guarantee that friends around him or even pedestrians walking on the street will not become assimilated monsters, so everyone is cautiously keeping away from others.

Perceiving this stiff atmosphere of distrust gradually spreading in the base, the joy in Yin Yiliu's heart also faded a bit.

Along the way, Xiaoxiao and Yin Yiliu talked to Yin Yiliu about her life in Z City Base in the past few months. She looked at Jin Yang who had been falling behind her, keeping a distance from the two girls, and her eyes flashed together. When he reached Yin Yiliu's side, he took the captain's arm and started gossiping.

She winked her eyebrows, turned her gaze behind her, lowered her excitement and asked in a low voice: "It's been so long, haven't you taken him down?"

Yin Yiliu had some embarrassment and embarrassment on her face, and her neck was stiff. She knew that Jin Yang's ears were so perverted that she could hear movement even thousands of meters away, not to mention Xiaoxiao speaking within a few meters sound.

Sure enough, Jin Yang, who had been following the two women all the time, heard Xiaoxiao's questioning, and his expression under the mask was taken aback, then his ears trembled slightly, and he listened quietly with holding his breath.

Yin Yiliu's eyes were covered with water. She didn't want to answer. She was so tight that she could only lower her eyes slightly to trick herself into not eavesdropping, so she suppressed her voice to the lowest level and let out a snort of "um".

Xiaoxiao's expression of excitement suddenly showed a faint crimson because of his excitement. She couldn't help shaking Yin Yiliu's arm, the huge wings behind her trembled constantly, and her voice could not be suppressed.

"Then you guys kissed? Is there such or that?! Is he very...well..."

Before she finished her words, Yin Yiliu gritted her teeth and covered her mouth. The remaining words were sobbed and blocked in her throat.

Jin Yang, who had been following silently behind him, looked at the bunny that stopped his companion from fleeing in front of him. The golden color in his eyes gradually rose. He gently raised the corners of his lips, and followed him in a good mood.

After settling down, Li Zhenjiang gave Yin Yiliu and Jin Yang permission to go to the scientific research institute in the city of z.

Just stepping into the silver-white building, Yin Yiliu was infected by the tense atmosphere in the scientific research institute, and the scientific researchers in white coats looked hurriedly tired.

The two of them sat on the special ladder in the research institute and went up to the largest floor at the top. After entering the one-time password given by Li Zhenjiang, the door with countless mechanical gears in front of them slowly opened.

Li Zhenjiang was standing outside the top-level laboratory. In Yin Yiliu’s impression, he had always been wearing a military uniform, and he had not changed his appearance. But at this time, the middle-aged man was wearing a robe from a scientific research institute, dragging silently. Chin looked at the scene in the laboratory.

There was silence around, only the footsteps of Yin Yiliu and Jin Yang could be heard.

Li Zhenjiang glanced sideways at the two of them, his eyes were bloodshot and his face was a little scary.

"You are back."

His voice was a little hoarse, but the frown that had been tightly tightened was slightly relaxed because of the two people's arrival.

When Yin Yiliu and Jin Yang left Z city twice, Li Zhenjiang said very seriously that if they get bored outside, they will return to the Z city base, which will always be their home.

So Li Zhenjiang said welcome home.

Yin Yiliu had long regarded this tough and gentle elder as a person he respected. At this moment, seeing Li Zhenjiang's appearance, she couldn't help frowning slightly, "How long have you not rested."

Li Zhenjiang waved his hand, pressed his sour eyebrows with his fingertips, indicating that he was okay.

He is now one of the few people who knows the truth about certain things, and the more he knows, the heavier the burden in his heart will be. Anxiety and depression are like a mountain that is deeply pressed on Li Zhenjiang’s shoulders, making him unable to breathe. .

He wanted to smile at his long-lost old friends. It was ridiculously bitter than crying. Jin Yang stared at his brows and said, "Don't laugh if you don't want to laugh, what's going on inside."

The three stood outside the laboratory on the top floor, and there were several scientific researchers in the laboratory, fully armed and wearing masks and isolation suits. They were standing in front of a huge operating table-like ice-cold shop, and on the platform lay a huge Humanoid creature.

To say that it was a creature is not entirely true, because at this time the body lying there and letting them dissect has become a corpse.

The body of the creature was about five meters long. Several scientific researchers stood by as if standing beside a giant. Because the front part was blocked by a layer of flowing wavy silver-patterned windows, Yin Yiliu could not see the whole picture outside. I can see a pair of huge black soles covered with hard scales.

The sole of the foot is similar to a human foot, but the arch of the foot is curved and the fingertips are hard and long. Each large main scale is also attached with small feather-like brown armor pieces to connect the hard armor.

This is a seventh-level darkener who was born in the desert with the eruption of the source rock after the rain. It is about to step into the eighth-level mark. It wanders at the junction of Z city. There are already two small towns in a row. The base was destroyed by it, and the method was extremely cruel.

It is said that the walls of the two cities collapsed, and the streets in the city were full of corpses. The dried and foul blood was condensed with various mutant bugs and beasts, like hell.

Just when this raging darkener was preparing to attack the third city base, mankind was fully prepared.

The Central Base and the surrounding areas of Z City jointly initiated the strangulation by the head of the Mercenary Alliance, the three ministers of the Military Department of City B, and several seven-level evolutionary powerhouses scattered around the large area.

The so-called companion darkening is not a monster created as the genetic fragments in the source stone merge with humans and occupy and assimilate humans, but the genes of higher species sealed in each source stone, which will be directly reproduced by the source stone. Shaping, whether it is intelligence or physical destructive power, is much stronger than ordinary mutant creatures.

According to what is now known, this companion darker is at least a super advanced species in its parent star, and the strangulation process is extremely difficult.

In order to ensure the maximum freshness of the corpse of this darker, several super bases decided to conduct anatomical research in the nearest scientific research institute in z city. Several top human academicians have been in the laboratory for a whole day, and Li Zhenjiang also Guarded outside for a day.

Just as Li Zhenjiang was talking, the light in front of the laboratory suddenly went out, he stopped and walked towards the glass in front of him, and looked inside.

"They are coming out soon."

Yin Yiliu and Jin Yang did not wear sterile clothes, so they could not approach the door of the laboratory. They stayed in the waiting room at the back of the floor for a few minutes, and then left again after confirming that the experimental body was sealed. come out.

At this time, the laboratory of the University of Science and Technology that could be seen before seemed to be split from the middle, and half of the space disappeared out of thin air. This is the method invented by the Z City Research Institute for the fastest storage of experimental objects.

Those who are able to participate in this experiment are the core figures of the current super bases, which can also be said to be the treasures of human scientific wisdom. Among them, there are some brain supplements that have undergone mutations, and they have extremely high control over the accuracy of the experiment. Eighty percent are very weak.

The high-intensity experiment for a day and a half made them too much for their bodies, so the main personnel were divided into two groups for the first and second half.

The person in charge of the second half was Z City’s own person, that is, the old white disciple who closed the door. After the female academician took off her protective clothing, her face was pale and her eyes were a little swollen.

After receiving the hot water prepared by Li Zhenjiang, she didn't have time to chat with Yin Yiliu and Jin Yang, so she spoke: "We did extract some strange things from the body of this companion darkening person. This kind of thing is It is not in the darker after being alien to humans-that is, this is the matter brought by the original star."

The source stone of the scientific research institute called the original homeland of these alien species as the origin star. After several negotiations with the darkeners, they already knew that it was a fallen planet.

No matter how brilliant and highly developed civilization once existed on the Origin Star, it has now dissipated in the long river of the universe, and only a batch of gene chains have arrived on Earth.

And it is impossible for human beings to give up their thousands of years of civilization and cultural heritage. This is a war between alien species invaders and native residents. ,

If it wins, it is a defense battle; if it loses, the human civilization in the history books is just a legendary story.

The academicians of several super bases have been working to find the relationship between the source stone and the end times, but there has been no substantial development.

The female academician pushed her own glasses and said: "We now know that in addition to the gene reproduction of foreign organisms in the source stone, there is also a special catalytic substance from the original star. The original intention should be to catalyze these gene chains. But for some reason, after three times of heavy fog dilution, it spread to the whole world, but the earth creatures used this substance to evolve first."

She paused for a while, and then said: "From this we can boldly guess that the earth has a special magnetic field. Since it can breed life, it means that it may have its own consciousness. It is this earth consciousness. It hindered the outbreak of these foreign genes and catalyzed the material in the source stone. But for some unknown reason, now the earth consciousness has disappeared. The heavy rain is a sign that it can no longer provide us with shelter, so those gene chains that have been suppressed It completely erupted on the earth, and a large number of darkeners appeared..."

Speaking of this, the female academicians have a sad and sad look on their faces. Maybe this is just their guess, but more scientific reasoning confirms that their research is correct.

There is indeed earth consciousness, but it is slowly fading and disappearing.

This is like the atmosphere covering the earth. Once the atmosphere is gone, the ultraviolet and infrared from the universe will cause a global environmental disaster.

And the earth consciousness is gone, and the protective layer that inhibits those alien species is gone.

Human beings are such soft and weak creatures that they don't have the strength to fight back in front of these invaders. What a sad thing.

"But fortunately, we finally made a new discovery in that big guy."

The woman sighed softly, stretched out her hand to make gestures with a few people, but slowly put it down.

"We captured the existence of'string'."
