Since the establishment of the Jiangnan Theater Defense Circle with Jinling City as the core, it has experienced countless battles, large and small. Or a tide of beasts formed by mutated creatures, or a large-scale insect plague. But these are all under control, the alien beasts that were originally mutated from the creatures on the earth are still not free from the limitations of the physical rules of this planet, even if there are many of them, it is a drop in the bucket in the face of the army with large thermal weapons, tens of thousands of mutant giant rats can be completely done with just a medium missile with a fixed strike, and for those insects with smaller and more scattered targets, special biological weapons are used, such as super-large insect repellent lamps and sound waves.

All of this is under the control of humans, although the Earth is starting to become a little stranger, and all kinds of strange creatures have been increasing lately.

Wu Yuan had been engaged in biological research before the end of the world, and if it weren't for the fact that she was hiding from some annoying guy in Jinling City, she would not have gone to the outermost county town of the defense circle to disguise herself as an ordinary military doctor. She had been doing research with the world's most senior biologists since she was a teenager, and for more than a decade, she had never seen the strange symptoms of that young man, a cone-shaped heart?

But she didn't have the time or heart to study the matter closely, as the fierce exchange of fire outside the gates indicated that the battle was scorching, and that the intruders were more terrifying than any before. The giant black worm left a pit about four meters deep in the ground, like a giant earthworm-like creature, wriggling in the ground like a fish in water.

With a violent tremor, a small slope arched over the open space of the guard area inside the city gate.

"Hurry up, it's the Ground Drill Worm!"

The small slope was broken like tofu, and the head of a worm the size of a car poked out, and the lamprey-like mouth was covered with layers of sharp teeth, and a hose about half a meter long was aimed at the target in front of him.

The Earth Drilling Demon Worm will only attack the first target it catches, and at this time, its target is Wu Yuan and the guards beside him.

"This is a juvenile demon worm!" Wu Yuan found out as soon as possible, because the research data of the Earth Drilling Demon Insect was in her hands! This kind of thing that does not belong to the known creatures of the earth seems to only appear in the area south of Jinling, and the demon insects in their adult stage are often more than ten meters long. The strange thing is that this creature usually appears irregularly, and has never actively attacked a human settlement!

With a "whoosh", a puddle of acid fell into the room, and even the metal door was corroded to a rattle, but the cement did not react.

Wu Yuan and the guards fled behind the wall the moment they saw the larva, so they didn't get splashed by the acid. After all, it is a larvae, and neither the quality nor the quantity of acid is as terrifying as that of an adult.

The guard opened the safety and fired several shots from his rifle, but the bullet did nothing when it sank into its body, which angered the larva, and he sprayed some acid in the direction where the guard was.

However, due to the obstruction of the wall, the acid did not work at all. I don't know if it's because it doesn't have vision, but it seems to feel like it's useless. So he squirmed, trying to climb over the fence and attack the two targets directly.

This was the first time Wu Yuan had observed this monster at such a close distance, under its black bag-like body, there was a dense pile of surging tentacles, about twenty centimeters long, it was these tiny tentacles that allowed it to squirm freely in the underground space.

The five- or six-meter-long demon worm quickly crawled to the edge of the wall, but what awaited it was the muzzle of a dozen black holes.

While dealing with the battle situation outside the city, the soldiers in the warning area soon discovered the movement in the warning area, and since the demon insects were also on the illustrated book, they could quickly dispatch teams to deal with them.

More than a dozen guns fired at the same time, no, it should be said that it was sprayed with water. These high-pressure water* guns were aimed at the juvenile demon worm. The moment its head poked in, it was completely covered by a column of water.

Incredibly, even the bullets were helpless for the demon insects, and their bodies were directly "cut off" by these high-pressure water flows!

The upper body of this five- or six-meter-long demon insect was cut out of several large holes by the high-pressure water current! Slimy liquid was gurgling out of the wounds.

The Driller is sensitive to water, which is a weakness they discovered in their research. Through the analysis of the underground burrowing area of the demon worms, they found that the burrowing insects always avoid areas with a lot of water. And for the larvae, the lethality of water to them is much higher! But Wu Yuan never thought that the effect would be so obvious, it was really one thing and one thing!

The larvae, which had been beaten by the water jet, wanted to escape into the ground, but how could these soldiers let it go so easily, more and more fierce water pressed on it, cutting off its upper body!

The broken upper body fell into a puddle of water with its head attached to it, and quickly dissolved into a puddle of liquid, while the half of the body in the deep pit kept bubbling with slimy liquid, and the dense tentacles on it stopped working after a moment of squirming.

It's completely dead!

The soldier was about to go up and talk about the rest of the stump being dragged away for study, but he didn't expect an even more violent tremor!

......

The captain, who was awakened by the vibration outside the warning area, sensed a trace of hot elemental aura from afar, and with the dissipation of this element, an even more intense fiery aura appeared! If it was a small bonfire before, now it is a heavenly fire that burns the plains! It felt like there was a huge stove at the city gate!

"What's going on over there?" Jiang Luo grabbed a person who came in a hurry and asked.

"Hurry up, the city gate can't be guarded, the monster has entered the city!" He tore Jiang Luo's hand away, hurriedly said a few words and ran to the back.

Monsters in town? Didn't you say that there was an army stationed here, and what monster could break through the previous fortifications?

With a "bang", the signal flare was lifted into the air.

Then there was a violent roar, which shook Jiang Luo's ears and buzzed, it was an artillery bombardment, a massive shelling!

However, even this did not seem to stop the monsters from invading, and after ten minutes of shelling, a group of disorganized soldiers withdrew from the warning area.

They were covered in dust and some slimy juice, maybe the blood of monsters.

And among this group of soldiers, Jiang Luo saw a familiar figure, it was the iceberg beauty doctor who had examined him before, she was puzzled at the moment, but her expression was definitely much better than expressionless.

Without waiting for Jiang Luo to think about it, the violent shock shook him to the ground. If the previous shock was only four or five levels, this shock should have eight or nine levels!

The sky was shaking, the houses were shaking off debris, and some wooden houses were crumbling into ruins.

The cement floor not far away cracked like a tofu block, and a six or seven meter insect head poked out, and through the undulations of the ground, it can be judged that this demon insect is at least ten meters long, this is an adult drill demon insect!

Just after they killed the small one, this big one appeared, and crushed the scene to pieces, the most terrible thing is that the high-pressure water * gun has no effect on this magic worm, and those "fire" soldiers were directly crushed into pieces by it.

Was it really just an accident that the larva was afraid of water? Does that mean they were going in the wrong direction from the start? Wu Yuan looked at the giant insect in front of him and thought, because of their overconfidence, hundreds of soldiers had already died for this.

This demon worm did not directly spray acid like it had encountered before, but crushed at the soldiers in front of it at an extremely fast speed. Its huge black body was like three large trucks side by side, mercilessly rushing towards the fleeing soldiers.

Fierce screams rang out one after another, and the giant truck was silently harvesting the lives of the fleeing soldiers. All the soldiers who had been run over by it were reduced to a puddle of minced flesh, and the air was filled with the smell of blood.

This was not the first time Jiang Luo had seen a bloody scene, but this kind of scene of humans being completely crushed by monsters was too terrifying and infuriating.

In the face of huge unknown monsters, even humans, armed with guns, are as small as ants.

"Sister Yuan, let's go!" The guards roared, holding rifles and shooting at the giant insects that were running at them, and in front of him, there were many soldiers like him, who did not run away, but used their lives to delay the speed of the giant insect invasion, hoping that the ordinary people behind him would have more time to escape.

Wu Yuan seemed to be frightened, and stayed where he was, looking at the giant insect that was close at hand, motionless.

Suddenly, she felt pushed by someone, and the tentacles of the giant worm passed by her, and the guard next to her was hooked by the tentacles of the giant worm.

Unlike the larvae, the giant worm's tentacles were more like steel hooks cast in iron, and the barbs on them plunged directly into the guard's abdominal cavity, and a stream of blood poured out of his mouth.

His eyes widened, and he swept towards the head of the giant worm, but the bullets landed on the giant worm like a mud cow into the sea, but the giant worm didn't care about the ant's dying throes, it just waved the tentacle at random, as if shaking off something dirty, and threw the guard under him.

Even if the body of a train ran over the guards, no one could find his bones.

Jiang Luo and the captain were desperately retreating with the stunned Wu Yuan at this time, and the guards just pushed her in front of them, and before they could think about it, they were squeezed into the second wall by the crowd, and through this iron gate, the giant insect behind them was only a dozen meters.

Gunfire continued outside the walls, while inside the walls were boiling.

It was a station, and many of the evacuation trucks were preparing to start, and only some people were able to leave in a car.

There were only a dozen trucks, and the crowd was far more than a few hundred.

If it was just a giant worm, it wouldn't have to escape, but it is said that only this giant worm came in, and there were more outside the city, and if it weren't for the troops on the north and south sides to contain it, I'm afraid the people in the city wouldn't even have a chance to retreat.

"Dr. Wu, is that you?" An officer on the side of the military truck who was verifying the passengers saw Wu Yuan in the crowd.

Fortunately, Jiang Luo and the others came early, although the crowd was crowded, they stood on a high place and were recognized at a glance.

The officer asked the soldier to make a way and walked to the beautiful doctor.

"Dr. Wu, get in the car quickly, if you die here, I will definitely be held responsible!"

Jiang Luo glanced at the badge on his shoulder, it seemed to be a regimental leader.

Wu Yuan said hello absentmindedly, and planned to get in the car with the head of the regiment.

"They're with you?" The regiment commander saw Jiang Luo and the captain and suddenly asked.

Wu Yuan thought for a while, his eyes fell on Jiang Luo, and he seemed to think of something all of a sudden.

"Take them with you!"

This female military doctor named Wu Yuan is so powerful? Jiang Luo sat on the military truck, feeling that he was really lucky, otherwise he would have to flee on foot with the captain.

"What do you feel?" Jiang Luo found that the captain was closing his eyes and recuperating, but his brows were furrowed, and in this case, he was sensing some strange aura.

"Strange, really weird. I seemed to feel a very primitive aura from the direction of the giant worm, just like the earth, no, not only the earth element, but also water and fire! ”

"Is there a Stranger over there?"

"I don't know."

Wu Yuan looked at the two muttering people, and also knew that they were most likely "deviants", and the young man with a cone-shaped heart, could it be because of the mutation?

What the hell is going on with those Ground Drilling Demon Worms, are all the previous research directions wrong?
