The Oasis Theory, known as the first and most important contribution of the Ark to humanity, points the way to the survival of humanity, or at least the survival of the remnants of the underground. Strangely, the Ark has been keeping this theory secret, and the existence of this theory is like a historical joke to the Ark. The person who proposed it, Lawrence Jason Todd, was only an honorary member of the Ark and one of the most well-known science fiction writers of the time, and this theory was only vaguely recognized by the Su Zhi family within the Ark, and even the scientists of this department did not complete its theoretical framework until the official discovery of Shangri-La on Island 1.

- "The History of the Development of the Underground Remnants? Volume I, IC 87, Curran Oak, Ferrans, Josiah

In the early morning of September 18, 2173, in the northeast of Zhongdian County, Diqing Prefecture, China.

The sniper position was set up in 30 minutes, the main protective wall was 30 meters wide, 2 meters thick, and 3 meters high on the ground, deep underground. The high-strength engineering cement was poured by the sapper shovel along the spliced steel bars to a depth of 15 meters underground, which greatly exceeded the known diving depth of the Sand Sea Demon Scorpion.

There is a watchtower on the left and right, and 1 flamethrower gun, 1 79-caliber escort machine gun, 3,000 bullets, and two groups of 4 fighters are responsible; 4 people were ambushed in the hidden soldier cave in the main wall, including Mo Gang, equipped with 3 high-explosive grenades, 1 thermal sword, 1 55-caliber automatic pistol, and 2 magazines; The scout was equipped with one 22.7 mm anti-materiel sniper rifle, three special armor-piercing shells, and 10 ordinary armor-piercing shells, and was completely buried in the back of an 82-meter-high sand dune for 1 kilometer ahead to support the shooting; Liu Guangyang was placed on a small sandbag 17 meters high at the back of the position, and his main task was to detonate and shoot the 20 high-explosive mines buried in front of the position.

"Lieutenant Colonel, it's all arranged." Captain Crane, who was like a black iron tower, quickly crawled into the hiding cave where Mo Gang was, almost squeezing Mo Gang out of the hole, he was the only non-yellow person in the sniper detachment, and there were originally fewer non-yellow people in the PRC17 shelter, and naturally fewer joined the army.

"Feng Kai is the best sniper, 1000 meters away, even if he scrapes a sandstorm, he can easily shoot those stupid big guys. Zhang Ji and Zhang Cheng are brothers, who are responsible for the flamethrowers on both sides, and they have a good heart. Xiong Degui and Zhang Dali are both shooters with excellent psychological quality and are responsible for machine gun support. The rest is you, me, Yang Gang and Sancho, it's all my head, you just have to rest assured. ”

"I haven't seen a second guy like you, it's strong." Mo Gang moved to the edge of the cave, changed his breathing position, and couldn't help but poke Crand's arm, which was thicker than ordinary thighs.

"Hey, hey!" Crane scratched his head and smiled embarrassedly, revealing his dazzling white teeth.

"Crane, I heard that your ancestors were tourists to Shangri-La?"

"Yes, she's from the United States and she's as beautiful as a black pearl."

"Don't learn the stupid way of describing white people, your parents, grandparents are all yellow."

"Yes, I'm a revival. The genes from 130 years ago reappeared in me, just to produce a great special soldier. ”

"Come on, go back to your own hole and squeeze me to death."

Crane returned to his hiding cave, and Mo Gang, who had just breathed a sigh of relief, heard Feng Kai's cold and clear voice on the walkie-talkie: "Lieutenant colonel, the target distance is 10 kilometers, the speed is 30 per hour, the direction remains the same, and the number of proven ...... 12 or more. ”

"Understood, keep watching. Liu Guangyang, do you hear that? ”

"Huh? Yes! In, sir! ”

"Scared?"

"I'm not afraid, I'm just a little excited, I don't know how many I can kill the next guy!"

"Okay, it's up to you to control the biosimulator if you can kill a few, and here you have a high degree of education, don't let those dim sum turn halfway."

"You can rest assured that the task will be completed."

Putting down the walkie-talkie, Liu Guangyang carefully turned on a machine on the sand jeep, which is one of the targeted inventions of the Ark, which can simulate the faint radio waves emitted by a large group of animals when they panic, and is the best bait in environments such as trapping and sniping.

Sure enough, as Liu Guangyang turned on the decoy machine and simply debugged it, Feng Kai's reconnaissance report frequency increased significantly: "The target distance is 8 kilometers, the speed is 35, the speed increases quickly, the direction remains the same, and the target is detected...... 15！ ”

"The target distance is 4 kilometers, and the speed of entering the sprint, the direction remains the same, and the number of targets is confirmed to be 15! I repeat it, and it is 15! ”

"The target enters the warning area, and after 2 minutes, the main position will meet the enemy, and the communication silence will begin, brothers, good luck!"

With the next call, the intercom entered a brief period of absolute silence. Liu Guangyang was lying in a simple camouflage in the sand dunes, holding the radio detonator of the mine tightly in his palm, sweating like pulp, which made him a little afraid that the detonator in his hand would be soaked in the gushing sweat, but he did not dare to wipe it, although the sand in front of the position was as calm as ever, but no one could guarantee the situation at the next moment, maybe the moment he released the detonation button to wipe the sweat, he would miss the best detonation time.

Mo Gang pressed his body against the inner wall of the cave, carefully distinguishing the distance of the group of sand sea demon scorpions through the cement, they were numerous, galloping, and could not be hidden like thunder underground, with experience, Mo Gang could easily distinguish the actual distance of the opponent's vanguard.

800 m ...... 600 m ...... 400 m ...... 300 m ...... 250 m ...... 200 meters.

"200 meters, explosion!" Mo Gang roared.

"Boom!" Liu Guangyang also roared hoarsely, and pressed the red detonation button with his thumb with the greatest force. "Boom! Boom Boom Boom! "The dense explosion of 20 high-explosive mines blew up and evaporated all the sand layers in front of the position 200 meters, forming a huge area of quicksand.

The quicksand formed a white vortex visible to the naked eye in the whistling sound, engulfing the blue blood and black stumps, and soon disappeared without a trace. A quiet roar came from the ground again, the source of the sound may not have been so dense, but it was more violent and unstoppable.

"Meet the Rush!" Mo Gang yelled into the walkie-talkie, "Collide! ”

"Boom! Boom Boom! "The sound of explosions farther than high-explosive mines sounded one after another in the ground, the main wall cracked out arm-thick cracks, the watchtower on the left collapsed, Zhang Ji fell with his flamethrower, and a huge pincer poked out of the gravel and caught him in the air.

"What a stupid scorpion, in the face of people who play with fire, do you have a direct claw pinch?" Zhang Ji coughed up blood and laughed, lit the muzzle of the gun at himself, the high temperature instantly carbonized half of his body, the fuel tank was ignited, and the fuel mixed with white phosphorus was splashed to half of the position with the explosion, and the scorpion that attacked him was ignited in its entirety. Hiss! He died with a strange scream.

But the second scorpion quickly smashed its charred shell and burrowed into the holes in the defenses created by the collapse of the bunker. A roar of a machine gun came, accompanied by a man's roar: "Grandpa is still here!" Don't even think about anything! Ahh ”

If a 7.9 mm caliber machine gun bullet hits a person's body, each shot can cause a hole the size of a baby's fist, but when it hits a huge demon scorpion with a length of 5 meters and a thickness of more than 20 centimeters, most of them only have sparks and ricocheting bullets flying everywhere.

The big eyes of the demon scorpion wandered around, and finally locked on Xiong Degui in the strafing, the scorpion tail was erected high, and the aiming was completed in the machine gun fire, and the tail needle pierced directly, only to hear "Boom!" A strange sound instantly stabbed the Heavy's upper body to pieces.

Shaking off the minced flesh on the tail spines, the demon scorpion swung its feet and limbs and was about to look for the next target, when another "Boom!" sound came from afar. A kilometer away from the mountain flew out of an orange-red flame, straight into the middle of the scorpion's eyes, a huge kinetic energy exploded in the scorpion's body, minced meat mixed with blue scorpion blood shot out from the crack in the armor, sprayed on the remains of the watchtower, and those red blood mixed into a cruel watercolor painting.

In the watchtower on the right, there are also 2 demon scorpions out of the gravel, Zhang Cheng roared and lit the flamethrower, aiming the fire at the nearest demon scorpion, Zhang Dali relied on the fortification cover, and suppressed the other demon scorpion by firing in the shooting hole, in the face of the bullets that came from the scorpion eye at all times, although the demon scorpion was still advancing, but the speed slowed down a lot.

"Ahh Come on! Come on! Zhang Cheng's eyes were as red as Chu, and the tragic condition of his twin brother stimulated his nerves at all times, and his flamethrower ignited the forehead of the demon scorpion, and then sprayed all the way down the carapace, but unconsciously exposed his body to the outside of the fortifications, and the scorpion burning all over his body "Hiss!" With a bang, the tail pin with fire flew out of the scorpion tail, and a blow stabbed Zhang Cheng's head, Zhang Dali hurriedly threw away the machine gun to hold the fire gun in fire, but the use of the flame gun must be silently counted for time, the barrel overheating will inevitably cause an explosion, Zhang Dali didn't know where to start, just picked up the barrel, jumped off the watchtower.

The scorching barrel scorched Zhang Dali's skin, the high temperature ignited the pure white combat uniform, and the fuel tank exploded in the air. The right pincer of the demon scorpion was held high and slapped horizontally, but it was still burned, although it paid a right pincer, but after all, it cleaned up the opponent in front of it, and now in front of it, only the undefended watchtower remained.

"Feng Kai! Right watchtower! Where's your sniper rifle! Mo Gang yelled, and in response to him was a noisy rustle, Mo Gang scolded hatefully, and yelled at Crane, "I'll go to the right, wait for me to come back!" ”

The frontal battlefield was also completely wiped out at this time, the thermal sword was specially created to cut through the carapace of these giant mutant creatures, and the 4-meter-long sword body was enough to ensure that the warriors could retain a pitiful distance when facing their opponents, but the innate strength and sheer size of these creatures still made the human warriors swallow the bitter fruit.

3 demon scorpions with a body length of more than 8 meters appeared on the front, Yang Gang jumped out of the hidden soldier hole, and cut off one of the left pincers of the demon scorpion in front of him with a sword, but it was swung by its right pincer, and flew several meters away, and even the thermal sword fell out of his hand, and the sword body composed of high-temperature lasers quickly melted the quartz sand into clear glass crystals, and slowly sank.

Sancho chose to hide behind the cover, and threw a bundle of high-explosive grenades high, and the demon scorpion, which was rushing out of the sand at high speed, could not dodge, and was concentrated by the explosion, and its huge body flipped over, and Sancho, who was catching up, dragged the ground with his sword, and cut the demon scorpion that was still in the middle of the meat and eight vegetables in half like a hot knife cutting butter.

"Junior intelligent creatures, if even you can ambush, then I will admit to death." Sancho handsomely retracted his sword, catching a glimpse of a black light out of the corner of his eye, and then the tail spines of the third demon scorpion pierced through his zenith, stabbing his entire body into pieces.

"Sancho! Damn it! Crand, who was nearly 2 meters tall, burst out of cover with tears in his eyes and cursed, the thermal sword he threw out failed to save Sancho, but it still cut off the scorpion's tail.

The scorpion turned to lock on to Crane, and couldn't help but let out a "hiss!" from the pain of the broken tail. Hiss! With a low roar, Crane's burly body stood tall and straight, with his hands behind his back, where he and Yang Gang's 6 high-explosive grenades had already pulled off the safes, and they only needed a slight knock to burst into bright sparks.

On the right wing, Mo Gang locked the tail pin of the demon scorpion with the help of the cover, then jumped high from the air, cut off its left pincer in the air, landed and cut off its locked scorpion tail, and finally turned around and swung his sword, cutting the demon scorpion in half.

But before he could catch his breath, out of the corner of his eye, he caught a glimpse of a high-explosive grenade dozens of meters away, carrying a high-explosive grenade, preparing to die with the demon scorpion in front of the position.

"Crane!"

"Lieutenant Colonel! Good bye! In the collision of the demon scorpion, the grenade in Crane's hand collided together, and the explosion wave rolled out more than 20 meters, and the broken tail of the demon scorpion and Crane were finally buried together, and each other failed to leave the last trace in the world.

Although Mo Gang was conscious of himself and his comrades at the moment he chose to snipe, he still felt that he was about to be crushed by the pain of losing his brother. Anger and pathos were like two spikes nailed deep into his pupils, and his vision became redder and brighter, like soaking in a pool of blood.

With black pupils, bright red eyes, and blue scorpion blood all over his body, Mo Gang at this moment is a real evil ghost, terrifying.

"It's painful to lose a comrade, little scorpion. Just like I feel, don't worry, I'll send you to meet them, your ...... Comrades-in-arms. Mo Gang pointed forward, and four thermal energy swords swirled in all directions, staggering and slashing, and the incomparable giant demon scorpion was instantly cut into countless fist-sized pieces.

Mo Gang turned around and withdrew his arm, and the four thermal swords flying in the sky also flew back behind him like swimming fish returning to their nests, hovering quietly.

Liu Guangyang ran over from the bunker in the rear, carried the unconscious Yang Gang on his back, and stood carefully on his side.

"Boy, did you just shoot it?"

"Yes."

"Then let's go, ditch the bait machine and head due south, the jeep can carry you up to 30 kilometers, and if you still can't catch up, you'll have to rely on your legs. Promise me not to abandon your comrade-in-arms on your back, he is a hero. ”

"Lieutenant Colonel, the demon scorpions have been killed, why don't you come with us?"

"Killed?" Mo Gang tilted his head and thought for a while, his blood-red pupils stared at Liu Guangyang's heart, "Yes, the demon scorpions have been killed, but I can't go." Mo Gang muttered and took a step towards the sentinel position 1 kilometer away, "Because the Demon Scorpion King is still there." ”

With Mo Gang's words, Liu Guangyang saw the huge sand dunes hidden by Feng Kai in the distance suddenly collapse, and the white sand slid down in all directions like mercury, gradually revealing a huge black figure.

Even if you don't count the scorpion tail of the same length, the body length of this magic scorpion has reached 20 meters, the carapace of the whole body is shining with metal, the two large pincers are serrated and clear, and the diameter of its tail needle has exceeded 20 centimeters.

The most memorable thing about the Scorpion King is its eyes, flashing with obvious viciousness and cruelty, as well as indescribable resentment, are these still eyes that a first-class intelligent creature can have? It shows more emotion than most adults.

"Boy, take a few more close-ups at the end, right to it, and then let's go. The last big drama is me and it. ”

With Mo Gang's low words, Liu Guangyang involuntarily raised the camera, and the picture was zoomed in to the maximum, and the Demon Scorpion King slowly tore Feng Kai's corpse and stuffed it into his mouth, but his eyes kept looking at Mo Gang's direction defiantly.

"Among men, I am special; Among the scorpions, you are special. I'm looking forward to this fight, I'm looking forward to it...... Suffer death! Mo Gang's voice suddenly turned high-pitched, and the four thermal energy swords behind him flew diagonally into the sky, and the quartz sand under his feet was also pushed up by an inexplicable force, forming waves dozens of meters high, like a giant beast born out of thin air, carrying him towards the flying streamer.

The Demon Scorpion King also left behind less than half of Feng Kai's corpse, swinging his feet and limbs rapidly, and did not dive, but just swept like a black tide, its tail needle stood high, and stabbed straight at Mo Gang's forehead from a hundred meters away, the speed even broke through the speed of sound, and the tip of the needle pierced the sound barrier, emitting a series of roars.

Mo Gang did not dodge or dodge, looked directly at the tail needle, 10 meters away, the tail needle seemed to be pinched by something, only to listen to "Hum!" With a bang, an invisible wave of qi burst out between the two, Mo Gang snorted and flew out upside down, and the Demon Scorpion King couldn't control the direction of the tail needle, and the terrifying long tail swayed from side to side at a strange angle.

But the Demon Scorpion King's huge size still prevailed, its tail needle was out of control, but the black tide did not stop smashing the wave formed by the quartz sand, and the left and right pincers were clamped towards Mo Gang. Mo Gang swung his arms together in the inverted flight, and two streamers of light flew down from the sky and slashed at the base of the double pincers, and the overwhelmed thermal energy hilt shattered, but it also cut off the double pincers.

The Demon Scorpion King didn't seem to know what the pain was, his feet and limbs flexed and stretched, his mountain-like body jumped into the air, and his sharp mouthparts kept opening and closing, the kind of agility didn't want to be a giant beast, but like a cheetah, it flew towards its prey, without a trace of clumsiness.

Mo Gang's eyes widened, and his arm was pointed in the direction of his mouthparts. At that moment, the scorpion king's mouthparts froze instantly, and a streamer flashed straight to the mouth, the demon scorpion king could not avoid it, the heat energy sword pierced through its mouth, and the high temperature formed around it instantly burned the mouthparts.

"Shhh Between life and death, the Demon Scorpion King let out a long hiss, and his abdomen suddenly bulged high, emitting a miserable green acid gushing out, destroying the firing mechanism of the thermal sword before piercing, and the sword body flickered unwillingly, and disappeared from the world silently.

A man and a scorpion landed at the same time. Mo Gang turned back to stabilize his body, kicked the ground to avoid the scorpion king's tail flick blow, and then grabbed it in the air, fanning the tail pin to the side again, taking advantage of its short loss of control, Mo Gang had already turned over and hung the scorpion tail, and then pounced on the scorpion's back.

The last blow, the corners of Mo Gang's mouth flashed with an incomprehensible smile, raised his hand and pointed, and the last streamer hanging in the sky landed, this is Yang Gang's sword, the sword is also bonded with glass-like crystals, constantly peeling off in high-speed flight, drawing a crystal band of light, the Demon Scorpion King hurriedly stabbed out the tail needle, straight to stab Mo Gang, it wants to kill the opponent before the invincible streamer hits it, and end this killing blow.

Mo Gang's smile became even stronger, and the streamer exploded as it approached his arm, and then shattered, Yang Gang's sword was already overwhelmed by overheating in the process of heating quartz, and he couldn't even afford a blow. But it was obviously impossible for the Demon Scorpion King to understand this, its tail needle had accelerated to a point where it could not be retracted, and Mo Gang turned around abruptly and raised his hand to pull the tail needle. The tip of the needle accelerated again, piercing through Mo Gang's abdomen and back, shattering half of his body while piercing through the Scorpion King's own carapace and into the brain.

"Lieutenant Colonel!" Liu Guangyang carried Yang Gang on his back and crawled to Mo Gang, he was completely shattered from the abdomen down, and he is not dead yet, but there is no possibility of continuing to live.

"Why haven't you left yet? Forget it, do you have a blood collection device? Bring a tube of my blood to the doctor, the dissection is impossible, it's all broken and shapeless, if it's a little later, I guess the blood will run out, haha. Liu Guangyang, when you go back, remember to tell the doctor my comment about that idiot demon scorpion king, intelligent creatures? Phew! Hahahaha! Hahahaha! Haha......"

Mo Gang died like this, 3 days later, Liu Guangyang carried Yang Gang on foot for 22 kilometers, and finally caught up with Su Zhi's large army, seeing those photos taken by Liu Guangyang, Su Zhi was silent for a long time, and finally put away the tube of blood, took out the paper order that Mo Gang gave him, and ordered the 2nd detachment led by Li Dajiang to be transferred to the guard of the science group.

On October 5, there were only 19 people left in the expedition, including Liu Guangyang, Yang Gang, Li Dajiang and Su Zhi, 7 soldiers, 3 scientists, and 9 assistants. Most of the instruments and baggage were discarded on the road, but these people were no longer afraid. In despair, there is nothing to fear.

Su Zhi was the first to get out of bed as usual and strolled up one of the highest sand dunes nearby. Facing the morning glow, he saw a scene that he would never forget. A vast forest as far as the eye can see lies in an irregular valley floor of a dozen sand dunes and two rocky mountains, full of verdant greenery and golden foliage. The two rivers that traversed it shattered the morning sun, and flowed out a field of broken gold, just as he and Mo Gang thought, everything was like a mirage of fantasy.

"The people who floated in this white sea finally found this green island. Shangri-La, I really found this place, but Mo Gang, you can't see it. Su Zhi muttered, letting go of his grip on his body, rolling and falling towards the strongest syllable of the human race returning to land.

On October 5, 2173, Su Zhi led the expedition of Vault No. 17 of PRC to discover Green Island, numbered 1, named Shangri-La, and the Green Island era began.
