The low roar that was close at hand and cold seemed to penetrate into the hearts of Hao Yi and Erin through the eardrums, making the two of them tremble together. Immediately after that, a faint tremor suddenly came up from the layer of viscous liquid under the feet of the two of them.

"Oh yes, what's going on?" Haoyi looked back in surprise, and heard a sudden sound of rumbling heavy objects rolling down the chimney-like passage behind him. Out of habit, Haoyi subconsciously raised his rifle, stood in front of Erin, and aimed at the exit of the black hole with his hand.

"Knock knock!" Listening to the four successive movements, it seemed that heavy objects were rumbling down in each passage. As the sound got closer and closer to the exit, a more unpleasant and somewhat warm smell of blood came out of the chimney passage, and went straight into the nostrils of Hao Yi and the two, so that Erin couldn't help but hold Hao Yi's back and retched for a while.

As if sensing that danger was approaching, Haoyi's face slowly turned from surprise to solemnity, and even the hand holding the rifle was slightly oozing a cold sweat.

"Boom!" Finally, the strange sound in the passage rushed to the exit, and a ball of blood, red, brown and yellow things slammed out of the passage, bounced on the thick and elastic ground, and swooped past the eyes of Hao Yi and the others.

"Snort......" Before Haoyi and the others came back to their senses, the strange thing slowly stretched out on the red ground. At the same time, an extremely unpleasant hoarse voice echoed through the huge cavern. As if to echo it, the rest of the corners around the "Pyramid of Flesh and Blood" also sounded one after another, and three or five such strange sounds came.

"Mom, what's the matter?" Under the white light of the simple flashlight, the mass of things lying on the ground finally revealed its true face. A worm about a meter long and looked like an oversized centipede, slowly wriggling on the ground. Its strange appearance made Haoyi and the others stunned.

The insect said it looked like a centipede, but in fact it was very different from the common centipede. Although it also has a pair of short legs, it appears to be much thicker than the usual centipede. What's more, its flesh and blood took on a purple-red hue similar to the main body of the strange pyramid, as if it had split from the pyramid. Moreover, on its back, from head to toe, there is a series of thick, yellowish-brown hard shells, which are cut off like the "armor" of a centipede.

In addition, the yellow-brown hard shell also had blood-colored barbed fangs, and at the place where the insect was about the head had a pair of thick and long fangs that were far thicker than the fangs on its back, and there were some irregular sharp barbs on the fangs. Compared with the common centipedes, the appearance of this insect in front of them is a little cautious and terrifying.

"W-What is this?" Although the bug was still at least three or five meters away from the two of them, Erin seemed to be able to feel it, and the disgusting aura emanating from the bug hit her nose. Coupled with its hair-curry appearance, Erin was naturally so frightened that she grabbed Haoyi's arm tightly and asked in a trembling voice.

Hao Yi naturally didn't know this strange alien creature in front of him. What he's worried about now is not whether it's called Zhang San or Li Si, but whether this fucking thing will take the initiative to attack him. If it was like a crab, ugly in appearance but still a human meal, then Hao Yi wouldn't mind roasting it for dinner. However, God knows if such a strange insect the size of a wolfdog will be the same ancestor as a piranha.

"Shhhh Don't squeak! Although it wasn't clear for a while what this ugly fat worm was, for safety reasons, Haoyi still turned around and whispered to Erin.

"......Snort" At the same time as Haoyi turned around, the ugly fat worm that squirmed vigorously on the ground suddenly opened the mouth of the blood basin the size of the casserole, revealing a series of large teeth with sticky blood, and let out a cry as if it was going to gnaw away people's nerves. Then, this ugly big guy actually moved his fat and bulky body, turned his head and approached Haoyi and the others step by step.

"What is it, what is it going to do? Hurry, run, Haoyi! Looking at the appearance of the fat worm who was slowly approaching, Erin was so frightened that she became a little incoherent.

"Dog's day, when Lao Tzu is your nurse!" Hao Yi naturally didn't regard this fat insect that pounced on him with teeth and claws as a harmless caterpillar, raised the rifle in his hand, took a slight aim, and gently pulled the trigger.

"Click!" A short burst, three spike bullets whizzed down on the fat worm that was close at hand.

However, the scene of flesh and blood splashing that Hao Yi expected did not appear. After three yellow 8mm spike blasters hit the hard shell on the back and head of the fat worm, they only exploded three sparks. After the smoke cleared, only tiny cracks were left on the fat insect's hard body.

After the "snort......" was hit, the fat worm's crawling figure froze forward, as if it was provoked by Hao Yi, and actually raised its basin-sized head from the ground, and "angry" at Hao Yi and the two of them let out an even more piercing cry.

"I'm X! Invulnerable? Haoyi was so shocked that his eyes fell to the ground with a chirp. Just when he was stunned, the ugly fat worm actually accelerated and crawled towards him. There was no doubt that this guy was trying to tear anyone who dared to fire at it to shreds with its sharp teeth.

"Hao, Haoyi, hurry, run!" Erin behind Haoyi was already frightened, although she screamed vigorously, her legs trembled disobediently, and she didn't move half a step after shouting for a long time.

"Click!" However, Haoyi doesn't seem to believe in evil. After coming to her senses at Erin's screams, she gritted her teeth and pulled the trigger hard at the fat worm. After a series of fierce gunfires, the fat worm was exploded by a series of small spike shells, and it was dizzy and took a few steps backwards. And between the series of explosive small fireballs of spike bullets, Haoyi seemed to see pieces of broken hard shells with dots of flesh and blood, scattering in all directions.

"Damn, you're not invincible!" Hao Yi was overjoyed when he saw this, and knew that the strange insect in front of him was not invulnerable, but just had thick skin and thick flesh. So, as soon as he saw the trigger pulled to the end, most of the remaining nearly thirty rounds of spike shells flew out of the muzzle of the gun with a whistling gun, beating the fat worm into a bloody flight. (The standard magazine configuration for the Spike Assault Rifle is a full magazine of fifty rounds) "Snort, Snort......" In the crisp sound of the Spike Gun, the fat worm let out a series of extremely piercing hisses, as if the dying was calling out to his comrades.

"Click!" When the rifle in Haoyi's hand made a sound of empty hang-up, the fat worm had already been beaten to a bloody blur. Except for the brown and yellow hard shell with barbs on the original back, which could be vaguely recognized, the rest of the fat worm's body was already full of terrible wounds of different sizes and blood, and even the original hard head could not be seen in its original appearance. What is surprising is that the "blood" flowing from the wound on the fat worm is actually a dark red and smelly liquid.

"......Snort" When Haoyi hurriedly put on a new magazine and was about to give this guy another shuttle, the fat worm let out a strange cry of life, and after a few convulsions on the ground, it was motionless and paralyzed.

"Damn, I still think you're King Kong's incorruptible body!" Seeing that the ugly and terrifying strange insect finally stopped moving, Hao Yi breathed a long sigh of relief, spat on the ground, and wanted to go forward to check the stump and broken arm left by the strange insect.

"Snort, snort......" However, at this moment, several of the same strange cries suddenly sounded in all directions. Hao Yi was stunned when he heard the sound, turned his head and looked at the strange pyramid, thinking that strange insects were running out of the passage again, but there was no living creature next to the entrance of the black hole.

"That ......" Erin, who was following Hao Yi closely, suddenly reached out and pulled the corner of Hao Yi's clothes, and pointed to the black place in front of him and said in a trembling voice.

"I'm X!" Looking in the direction of Erin's finger, Haoyi saw an almost identical fat worm crawling on the ground in the distance. "Holy shit, isn't it over yet?" Haoyi was so angry that the bullet was reloaded, and he picked up his rifle and prepared to shoot at the place where the fat worm had no hard-shell armor.

"Snort......" When Haoyi's finger just hit the trigger, several strange screams suddenly sounded behind the two of them. Listening to the unusually clear movement, it seemed as if it was close at hand.

"Mom, so much?" Haoyi looked back and was startled. I saw that less than ten meters away from him and Erin, four or five ugly fat worms slowly wriggled. It seemed that there was a guy coordinating between them, and they faintly put on a posture of encirclement towards Haoyi and the two. Except for the strange pyramid behind them and the crooked chimney passage, all the routes leading to the entrance of the cave by Hao Yi and the others were almost sealed by these fat worms.

"What should I do, Haoyi?" Erin was so frightened by the formation of the fat insects that she almost cried, she didn't want her white and delicate body to be bitten by these ugly strange insects that exuded a disgusting smell all over her body.

"What to do? Fuck the shit! Hao Yi gritted his teeth and said a word of hatred, so he raised his rifle without hesitation, aimed at the nearest fat worm and pulled the trigger.

"Da Da Da!" This time, in order to save limited ammunition, Haoyi no longer swept blindly, but relied on the accurate infrared laser sight on the rifle to shoot at the places where the fat insects were not protected by a hard shell.

"Puff puff!" The series of explosions produced by the spike bullets when they burrowed into the fat bodies of those strange insects caused the fat insects to spill pieces of flesh and blood and puddles of dark red "blood" on the ground with every step forward.

The vitality of the fat insects seems to be extremely tenacious, and where there is no hard shell protection, there are probably non-lethal torsos. Even so, under the bombardment of spike shells that could tear through thick and hard steel armor, the fat insects were still quite vulnerable. Coupled with the slow crawling speed of the fat insects, Haoyi has enough time to slowly aim, adjust the shooting target and even change the magazine.

Finally, in the unpleasant screams of the fat insects, Haoyi emptied the fourth magazine and replaced it with a magazine from Zuihou. However, at this time, a fat worm also fell on the "wild boar-style charge" route.

"Hu ......" didn't know whether he was too nervous or too excited, Haoyi's shoulder was a little numb from the continuous firing of the rifle. Seeing that there was only one magazine left, Haoyi even planned to find a few high-explosive grenades to try, God knows how many more fat worms there were.

"Whew......" After gasping for a few breaths, Haoyi was about to turn around to say hello, and Erin, who was covering her ears and closing her eyes behind her, escaped from here together. However, at this moment, with another low and angry roar coming from the pyramid behind them, there was a violent tremor on the ground under the feet of Hao Yi and the others.
