With a click, the brocade box slowly opened.

Nan Zheng opened the heavy lid of the brocade box, and when his eyes touched the things placed in the box, his tall and sturdy body inevitably stiffened for a moment. For no other reason than the fact that at the bottom of the box was a container made of tempered glass, with formalin-soaked --- a heart that had long since ceased to beat.

The heart was clearly not a voluntary donation, as it was surrounded by scattered pieces of minced tissue, fragmented nerve fibers fluttering underneath the heart, and fragments of organs that could not be seen in shape. It looks like a heart that has been suddenly blasted out of the human body, but it has a highly intact appearance.

Such a contradictory existence obviously touched Nan Zheng a lot, and he stretched out his hand and carefully picked up the container made of tempered glass, staring at the heart that was no longer beating alive soaked in formalin solution.

"This heart...... What does it mean? Nanzheng's pupils clearly reflected the intact appearance of the heart, as well as the fragmented flesh and organs underneath the delay.

"This heart belongs to the ...... in the former first battalion" Before the words fell, the military doctor slowly looked away, raised his hand to wipe away the tears that slipped from the corners of his eyes: "Comrades in the first battalion." "The heart that is no longer beating alive is the last bit of memory that Yun Luan brought back with all his might, and it proves the existence of his comrades-in-arms.

Hearing the military doctor say this, Nan Zheng raised his eyes in disbelief.

"Why, don't you believe it?" The military doctor's voice was obviously impregnated with crying, he barely suppressed the burning emotions in his chest, trembled slightly and carefully took the glass container with his hands, and his moist eyes stared at the heart that was rising and falling inside.

Nan Zheng silently handed the glass container to the military doctor, and after thinking for a long time, he slowly spoke: "I don't believe it, this heart...... How did you get it? He stared at the side of the doctor's tearful face, and the extreme emotion of the other party made him feel sad from the depths of his soul.

The military doctor pressed his warm jade-like face against the glass wall very lightly and slowly, and he looked at Nan Zheng through the formalin solution: "This heart was blasted out of the human body after being shocked by sound waves, and the underground palace of butterflies is full of too many traps, and the sound waves have taken the lives of many comrades-in-arms. ”

Although the military doctor said it lightly, the Southern Expedition could still feel the sinister severity from it, or rather, what happened at that time was far more terrifying than the picture he could imagine, and even beyond the limits of human imagination.

Nan Zheng pursed his pale thin lips, and his handsome and extraordinary face became more and more hideous and painful as he got closer and closer to the truth behind the fog: "Sonic shock...... Is it enough to shake the level of the building? He asked in a hoarse voice, word for word.

The military doctor felt the coldness on the glass wall, and said with a nervous smile: "That's right, that kind of sonic shock makes all underground buildings tremble, but how can 'butterflies' be willing to kill all the nutrients sent to their mouths?" What they want...... But it's the sustenance of life. ”

The living nourishment is so tender and delicious, far fresher and more attractive than the dead nourishment.

Nan Zheng only felt that there was a large carefully woven net hanging above his head, and there was a cold and sharp light flashing on it, and the first battalion of the year was tantamount to livestock that had been raised and fattened by the military high-level, and after they grew to a critical point, they would be sent to the slaughterhouse mercilessly by the high-level military leaders.

And then in exchange for maximum benefits.

Thinking about it so far, Nan Zheng only felt cold all over his body, and even the liquid medicine that dripped into the blood vessels along the infusion tube was cold. The cold had been soaked into his bones, and all the bones and blood in his body were tightly glued together, like a machine in disrepair and unresponsive.

When he tried to get up and walk to the bed to bask in the sun, trying to dispel the chill to the bone, he found that no matter how hard he tried, he could not control and awaken the adhesions and stiff limbs. Nan Zheng had no choice but to sit silently, sitting gloomily on the bed, letting his body be completely enveloped by a bone-chilling cold.

The heart soaked in formalin's solution floated slightly, and the military doctor looked at Nanzheng's confused face through the glass wall, and said again: "You know, the butterfly's nest is magnificent, I even thought it was a magnificent relic left by other life in the vast universe, until those electronic machines fired infrared lasers that were enough to cut everything, and I realized that --- everyone was very wrong. ”

The military doctor withdrew his gaze from the southern expedition and refocused his gaze on the heart in the formalin solution: "That magnificent and majestic underground palace is simply a large, cold-blooded slaughterhouse, where butterflies nourish the existence of the entire kingdom with human flesh and blood. ”

The words he uttered were extremely cold, without the slightest emotion, but how could such a bloody, disgusting and dark existence match the slightest emotion of human beings?

Because that 'butterfly's underground palace is a complete dirty slaughterhouse!

They treat people, the soldiers of the first battalion of the year, as livestock to be slaughtered, and enjoy the pleasure of slaughtering in the process of wanton tossing and turning. When they have had enough of playing and are tired of it, they will easily and happily press the command that represents killing, and then slaughter all the living humans into nourishment.

"You haven't experienced what happened back then, so you'll never put yourself in my shoes and feel the pain and resentment in my heart." The Medic put the heart-soaked glass container back into the brocade box, and then carefully put it back into the cabinet after skillfully placing the combination lock and the outermost lock.

He turned around and sat back on the leather chair, staring at Nan Zheng's gaze intertwined with many complex emotions: "I watched my comrades-in-arms' bodies being cut, shattered, and blown into unconscious ...... The warm corpse, the feeling of powerlessness and yet fear and panic, is really a nightmare for a lifetime. ”

Nan Zheng moved his thin lips, wanting to say something but no longer had the courage to ask. At this point, he had gradually guessed the truth of the whole thing, but he didn't have the courage to tear through that layer of fog, he didn't have the courage to tear through that layer of beautiful lies, and face the bloody truth.

The military doctor collapsed on the leather chair, and his mind was like a movie replay, automatically playing the bloody and tragic scenes of the year. Seeing the tragic deaths of his comrades-in-arms one after another, but there was nothing he could do, and the darkness ahead was full of more unknown crises.

Blood, broken bones, organs.

These three things are enough to build a hell on earth.

In his life, he can never forget the sticky touch of stepping on a pool of heavy blood, let alone the body of his comrades who were cut into pieces by infrared lasers, those comrades who were subjected to sonic shocks, explosion impacts, and sulfuric acid cautery, and fire were all dead and blind, and their tragic death was deeply engraved in the minds of the military doctor like a magic spell, and he had nightmares all night long.

Why, exactly?

Why did the top brass of the military send the first battalion of the year to the dirty and criminal slaughterhouse of 'Butterfly'?

The heart soaked in formalin's solution was the ultimate answer.

The golden glow of the warm sun shines through the clear glass on the floor tiles of the infirmary, and the infirmary, which is based on pure white, is simple and clean, but it is cold and deserted, no matter how hard the sun tries to warm the room, it has to be frightened away by the cold and cold hidden in it.

As a result, little by little, the beam shifted to the west.

The circular halo floated and sank in the gilded golden beam, Nan Zheng raised his eyes to look at the warm glow by the window, and finally whispered after a long silence: "Back then, how did you escape?" "How to escape from that road to hell full of ups and downs, bloody despair.

"It's Miss Yun." The military doctor's reply was concise and to the point.

"Yunluan?" Nan Zheng frowned slightly, recalling Yun Luan's unfathomable strength and exquisite martial arts during the competition, but he also believed a little. But in such an underground palace full of various high-tech procedures, it was impossible to lead Instructor Luo and the military doctor to escape with martial arts alone.

The military doctor blinked, and his warm and jade-like eyebrows looked picturesque in the sunlight: "Yes, don't underestimate Miss Yun's strength and wisdom, at that time, Instructor Luo and I were both seriously injured, and it was Miss Yun who led us to escape after we urgently treated our injuries." ”

At this point, the military doctor slowly rolled up the long-sleeved shirt, and it was really a strange thing to wear a long-sleeved shirt in such a hot summer, but after a long time, the soldiers did not feel new about the military doctor's style, and thought that the military doctor was afraid of cold, so he wore long-sleeved shirts all year round.

"You see, this is the scar left by the escape." The medic rolled up the sleeves of his shirt, and his thin arms were covered with hideous scars, either raised or dented, and one of the wounds seemed to have been deeply cut by a sharp weapon, and the musculature that had grown in the wound took on a dark red and purple horror color.

The military doctor pointed to the raised scar that extended straight from the shoulder to the wrist, and his slender fingers gently and slowly stroked the rough touch of the scar: "This scar was left by the infrared laser that I couldn't dodge, and just affected it, I almost cut off the entire arm." ”

He curled the corners of his lips and smiled meaninglessly, the hideous and horrible scar as thick as two fingers together, straight through the entire arm of the medic. Coupled with all sorts of other places, or beaten, or bruised, or burned, they together look like a stout and hideous centipede.

Immediately afterward, the medic turned around and drew the curtains and locked the door to the infirmary. He took off his entire long-sleeved shirt and turned slowly.

Nan Zheng's eyes widened in disbelief, his body trembled slightly, and he only felt that the warm blood flowing all over his body suddenly condensed at this moment. I saw that on the back of the military doctor, there was no inch of intact skin, as if someone had forcibly stripped off the skin, only dark black flesh and blood wounds remained.

The whole back is dark black after being severely traumatized, and the joints of the vertebrae can be faintly seen undulating, and after the southern expedition is almost done, the military doctor slowly put on his clothes, and his expression is extremely light: "If it weren't for Miss Yun, I would have died in the ground and my bones would have been gone." ”

Nan Zheng pursed his pale thin lips, his right hand was clenched into a fist and slowly released, and then clenched into a fist again: "This injury...... Is it a scar from a burn? Although it was a questioning tone, Nan Zheng's gaze was very affirmative and unquestionable.

The military doctor smiled, his smile was extremely pale and weak: "What do you say? ”

He smiled and asked back, but Nan Zheng clearly felt that --- other party was crying.

"The injuries on my body are not important, the important thing is --- the injuries here." The military doctor raised his finger to his chest, where the beating heart was: "The injuries here can't be healed in this life, not only me, but also Miss Yun and Instructor Luo." ”

The military doctor slowly lowered his arm, and suddenly felt the hideous scars on his body that had been calm for many years, and there was a faint pain: "Miss Yun and Instructor Luo are skilled, so they have not been seriously injured, it is ridiculous to say, it is the high-ranking military who pushed us into the fire pit, but in the end, it was they who saved the lives of the three of us." ”

Speaking of this, the smile on the military doctor's gentle face was very cold and sarcastic, and he looked around the surrounding environment, only to feel a faint nausea in his stomach: "If it weren't for those elite weapons and medical supplies distributed to us by the military elite, I'm afraid the three of us would have been buried in that filthy and rotten underground palace a long time ago." ”

He still clearly remembers that on the way to escape, Yun Luan desperately mobilized the strength of his whole body in order to protect the seriously injured Instructor Luo and him. It was all the internal force that had been accumulated in the dantian after cultivating the inner kung fu, and Yun Luan forcibly operated for two days and two nights without sleep, and finally fell to the ground from exhaustion after dragging them out of the exit of the death dungeon.

Since then, when Yun Luan cultivated his inner kung fu, he felt more and more difficult, which was the negative impact of harming the body's foundation, and that negative effect was often irreversible.

In other words, it is impossible for Yun Luan to cultivate to the top of the peak of the inner family kung fu in this life, at most he will hover at the top of the fifth order. This is no less than a devastating blow to the arrogant Yun Luan, but Yun Luan has no regrets in this life to be able to exchange half of his foundation talent for the lives of two comrades.

Whenever he saw Yun Luan hesitating on the bottleneck of a high-level breakthrough because of his damage to the foundation, the military doctor felt that blood was dripping from his heart.

Not only that, but by December 21 every year, the anger and resentment in his heart almost burned through his chest. On this memorial day for comrades-in-arms, the military doctors, Yun Luan, and Instructor Luo gathered together in the cemetery, where there was a luxurious cemetery built by the military elite at a huge cost in order to hide people's eyes.

But what's the point?

Those comrades-in-arms who died blindly, were buried in the underground palace of 'butterflies' forever, and their flesh and blood bodies had already turned into nourishment for butterflies, and they were eaten up little by little.

The heart that belonged to the comrades-in-arms was preserved by Yun Luan with all his might, and the last little bit proved that the comrades-in-arms had existed. The icy formalin solution soaked the heart, and the tempered glass preserved a heinous sin hidden under a beautiful lie.

When a new dawn of the future comes, tearing through the darkness of heavy sin, those ugly demons who kill innocent lives for their own selfish desires will eventually suffer a bloody, hideous and terrifying punishment and bad luck that is a hundred times more bloody than the destruction of the battalion back then!

It just takes time.

It's just a matter of waiting.

The military doctor stood in the infirmary like a statue, his eyes stared directly at Nan Zheng, but Nan Zheng could clearly feel that the other party was not looking at him, but looking far ahead through his body, shuttling through time and space to see the tragic and gloomy picture of the past.

"The next thing, Miss Yun will tell you personally." There was silence for I don't know how long, and it seemed like only a moment had passed, the military doctor said.

What's next?

Of course, it is the truth that Nanzheng does not dare to touch.

"Yunluan...... Is she still looking into the matter? Nan Zheng raised his eyes to look at the liquid that had descended to the mouth of the bottle, and the blood in his whole body was gradually warming, giving him a more and more cold touch.

The military doctor took out a mint cigarette from his coat pocket, and after he pressed the lighter and lit it, he first took a big gulp, until the throbbing cranial nerves and intense emotions slowly calmed down a little, and then he softly replied to Nan Zheng's question: "Well, Miss Yun has been investigating the events of the year, but a lot of evidence has been erased, and even the witnesses have been erased one after another, so the investigation is very difficult." ”

He slowly exhaled a puff of pale blue smoke, his gaze rarely softened, and he looked at the white wall where the clock was hung: "After all, Miss Yun's identity and status are there, and the military elite doesn't know that we have already seen through their sinister faces, so they haven't erased our existence." ”

At this point, the military doctor suddenly turned his head and stared at Nan Zheng's starry eyes and smiled coldly: "But my identity is confidential, even my face has been repaired after plastic surgery to become what it is now, otherwise it should be a face full of scars and ghosts." ”

He raised his hand to caress the face that was very unfamiliar to him, but also very familiar, and smiled sarcastically at the corner of his lips.

Nan Zheng looked at the movements of the military doctor, only to feel that his heart was becoming more and more cold, but he didn't expect that the other party was not only a fake identity, but even the face in front of him was also fake. However, these things are taken together, and they also reflect from the side how tragic the situation suffered by the first battalion that year was.

It was a hell created by man.
