Shi Ling lifted the stone and slammed it down.

With a "porphyry" sound, the green juice mixed with the shattered hard shell splashed up and hit him in the face, making a soft "snort" sound.

A faint green smoke immediately emitted from the place where Shi Ling's face was splashed with green juice, and this green juice contained corrosive poison.

Lin Yang fell to the ground, his throat was bitten off, and hot blood was bubbling out of it, and the bite of his throat was an ugly green worm more than a meter long.

The appearance of the green insect is very similar to the common vegetable green worm, but the body is twenty or thirty times larger, the whole body is blue, fat and round, there are small tentacles under it, the head has a hard shell, the face is hideous, and the open mouth is full of sharp and thin teeth.

Lin Yang hadn't lost his breath yet, and hugged the green worm with both arms.

Shi Ling held the stone and smashed it frantically, and finally smashed the head of the giant green worm into a ball of green juice and pulp.

Seeing that the giant green worm was dead, Shi Ling threw away the big stone in his hand and desperately pulled Lin Yang who fell to the ground, tears rolling in his eyes.

"Lin Yang, you can't die-" Cheng Lin on the other side was already crying like a tearful person.

Lin Yang's lips trembled slightly, as if he wanted to say something, he opened his mouth, a large amount of blood gushed out, his throat was completely torn open, and he couldn't live anymore.

Shi Ling hugged Lin Yang tightly, trembling all over, it had been three days.

Of the people who are still alive now, only Shi Ling, Cheng Lin and Lin Yang remain.

Lin Yang is his best friend.

Now, is Lin Yang going to die too? When did you talk about him and Cheng Lin?

"Shi ...... Mound...... Live...... Alive...... Walk...... Walk...... Out of the ......" Lin Yang's pupils dilated, and he desperately opened his mouth wide, and blood began to gush out of his eyes, nostrils, ears, and mouth.

The giant green worm not only tore open his throat, but the toxins in his teeth even invaded Lin Yang's blood.

"Let's go...... Go out...... Go ......" Lin Yang finally lost his breath after saying this sentence with all his last strength, his eyes rolled and the hand that had been raised slightly hung down silently.

"Lin Yang......" Shi Ling hugged Lin Yang's body that was slowly getting cold, his voice was hoarse, and he was already crying without tears.

Cheng Lin was silently wiping her tears, her snow-white fine teeth, and biting her lower lip.

They are all classmates of an ordinary university, the summer vacation is coming, the class leader Fang Zhen proposed that the class of 27 people go to the "Tianzhu Mountain" to travel, 27 people rented a minibus, no one expected that the minibus they were riding in would be hit by something like a meteorite falling from the sky halfway.

At that time, Shi Ling didn't understand what was happening, he only felt that the minibus vibrated violently, and there was a fire in front of him, and then he passed out.

When he came to his senses, the minibus was burned to a charred black iron shell, and a total of 28 people, including 27 students and a driver, died on the spot, and the tattered corpse and tragic situation made Shi Ling vomit on the spot.

Only twelve remained alive.

The falling meteor hit the minibus, breaking the ground, blasting them and the minibus into the depths of the earth's crust, where there was no mobile phone signal, no distress signal, and no rescuers were seen, and the twelve people who were still alive could only save themselves, walking along this terrible crack in the earth's crust to a place that might be an exit.

Halfway through, they were attacked by all sorts of terrifying giant monsters.

These strange insects include mosquito-like monsters that are one or two meters long, giant cabbage worms, and praying mantis that is nearly two meters long with a green body.

The experience of these three days was like a nightmare, Shi Ling watched Fang Zhen, the squad leader who had a good relationship, being caught by the monster like a praying mantis, and being frantically gnawing the flesh on his head and face.

Fang Zhen struggled desperately and screamed, the flesh on his face was torn off piece by piece, and his eyes were poked out.

By the time they desperately lifted the stone and smashed the nearly two-meter-long praying mantis to death, Fang Zhen was almost insincere, his whole face was blurred with flesh and blood, and he couldn't recognize this as Fang Zhen who had been lively and cheerful, and had excellent leadership skills and popularity.

Seeing Luo Yuxin, who was secretly rated as the flower of their class by a group of boys, was entangled by a strange insect like an earthworm more than a meter long, when Luo Yuxin opened her mouth and screamed in horror, the earthworm monster suddenly stretched out, burrowed into her mouth, and quickly squeezed it out of her mouth and drilled into her body.

Luo Yuxin was in pain and frightened, rolling and twisting all over the ground, and finally all the internal organs were crushed, her chest cavity was ruptured, and the terrifying scene of her tragic death was unforgettable for Shi Ling.

In just three days, only Shi Ling, Cheng Lin and Lin Yang were left among the twelve people who were still alive.

Now, even Lin Yang is dead.

Slowly putting down Lin Yang's corpse, Cheng Lin on the side suddenly said, "Shi Ling, you kill me." ”

Shi Ling turned his head to look at her, Cheng Lin's originally quite delicate and lovely face was full of fear at the moment.

"We ...... I can't live, I don't want to be killed by such a monster, Shi Ling, kill me...... Please, kill me—" Cheng Lin tugged at Shi Ling's sleeve, she had been driven to the brink of collapse by fear and despair.

Shi Ling looked at her frightened face, watched her burst into tears, just stretched out his arms, hugged her trembling body tightly, his eyes stared at the distance where he could not see the deep pit and crack in the sky like a hole in the ground, and muttered: "No, we won't die, we will definitely be able to get out, I Shi Ling will not die in this kind of place-"

Shi Ling took a deep look at Lin Yang's corpse and picked up the backpack containing food and fresh water on the ground.

On this trip, they brought with them a lot of food and fresh water, such as bread, biscuits, and mineral water, otherwise three days of hunger alone would have consumed all their physical strength.

Shi Ling knew that he was about to reach his limit, he had to take advantage of the little strength he still had to drive out, even if there was only one ten-thousandth hope, he couldn't give up, he didn't even have the ability to bury his good friend's body now, so he could only grit his teeth, drag Cheng Lin, and run towards the end of the crack.

Shi Ling noticed that there were serious signs of scorching on the surrounding earth walls, and there was even a faint stench, which had never been seen before, and this discovery made him think that there must be something at the end of this crack, maybe it was an exit.

The more he walked, the more he confirmed his thoughts, he dragged Cheng Lin and ran away, and soon, the signs of burning around him became more and more obvious, and there was a smell of burning everywhere.

"Cheng Lin, we may be saved, this is the end of the road...... There must be something ...... along the way" Shi Ling dragged Cheng Lin's hand and let go suddenly, and he suddenly stopped as he was running.

At the end of this crack, it was not the exit he imagined, but a huge mechanical instrument sunk into the scorched earth and rocks, and the terrible cracks in the rocks.

The appearance of this instrument is like a bell, and at this moment it is obliquely inserted between the burnt earth and stones, Shi Ling suddenly woke up, maybe the huge deep pit cracks that he and others have walked all the way over in the past few days are actually the cracks left by this bell-like instrument to break the earth?

Unable to imagine what a terrifying power this was, Shi Ling faintly felt that the culprit of the catastrophe that he and the others suffered was the strange instrument like Zhong Ding in front of him.

The instrument is like a combination of metal squares standing upright, the metal squares are constantly fluctuating and changing, and each metal square is carved with strange patterns, and the patterns are constantly changing, combining a pattern that is completely different.

Cheng Lin, who was about to collapse, looked at the instrument that suddenly appeared in front of him, and was also stunned, looked at Shi Ling, and then looked at the strange instrument in front of him.

Both of them can feel that this instrument is not like a technological civilization on the earth can be created, this strange instrument is very similar to the high-tech masterpieces of the future world or aliens that they may only see in science fiction movies.

"Could it be ......" Shi Ling licked his dry lips, for college students of their generation, they usually read some fantasy novels or science fiction films, and their imagination is quite rich, but at this moment they suddenly saw this strange instrument that seemed to be constantly changing, and they had to think about alien technology.

"Could this be some alien spacecraft? What happened to me and I fell down and hit our car? Cheng Lin on the side, like Shi Ling, immediately thought of the aliens.

Although it has not yet been confirmed that there are aliens in the universe beyond Earth, even scientists cannot be sure that aliens do not exist.

"If yes...... Will there be aliens here......" Shi Ling said this, and suddenly felt a burst of creepiness.

Although in science fiction films, they saw all kinds of aliens, and even shouted wonderful when they watched it, but at this moment, when they thought that this thing in front of them was very likely to be an alien spaceship, and even when there were real aliens inside, Shi Ling and Cheng Lin felt instinctive fear.

Because of this fear, Shi Ling and Cheng Lin looked at the strange instrument in front of them, and they didn't dare to approach for a long time, but only dared to look at it with their eyes.

"What now?" Cheng Lin asked quietly, her beautiful eyes still full of fear.

Shi Ling groaned slightly, he had been paying attention to this strange instrument, the more he looked at it, the less it looked like a spacecraft or a spaceship, at least there was no such shape in the science fiction movies he had seen, and it couldn't be so small.

Shi Ling, who was groaning, slowly scanned the instrument with his eyes, and suddenly noticed that a small earthworm slowly crawled out of the mud on the side.

The earthworm crawled out hard, and soon got out of the mud, and looking at the direction of its crawling, it was crawling towards the device.

When the earthworm climbed onto the instrument, a strange scene appeared.

The pattern that was constantly flickering and turning on it suddenly cracked and fluctuated, and one after another light waves were released, and in this light wave, the body of this little earthworm began to twist and expand, and it became more than a foot long in the blink of an eye.

"Ahh
