That low roar was like a demonic cry coming from the Nine Hells, and it was actually with an infinite chill, penetrating straight into the depths of people's hearts without warning, making people's souls tremble subconsciously.

"Fuck! What the hell is calling? Rao is Haoyi is also a veteran of a hundred battles, and when he heard this roar with a bit of caution and horror, he was also frightened and his heart jumped. Even the simple "flashlight" in his hand seemed to give birth to an induction, and it flickered strangely.

"W-What is it?" Erin, who was still grinning at Hao Yi just now, flashed behind Hao Yi at this moment, tugged at Hao Yi's sleeve, and asked in a trembling voice with her upper teeth and lower teeth.

"Maybe it's a lonely ghost who died unjustly!" Out of the corner of his eye, he caught a glimpse of Erin who was trembling, Haoyi was amused in his heart, and deliberately scared him.

"Ahh Poor Erin really screamed in fright, subconsciously hugged Haoyi from behind, shrunk her head and closed her eyes, and muttered in her mouth: "Don't come to me, don't come to me......"

"Tut-tut, this elasticity is so good!" Enjoying Irene's "proud breasts" personal massage again, Haoyi was actually amazed in his heart with great interest. After a while, this thing wiped the saliva from the corner of his mouth and comforted Erin: "Auntie, don't worry, even if there are evil ghosts, I'll let him eat me first!" When he finishes eating me, he will be full, and he will not bite you! ”

"Really?" Haoyi's child-like words actually worked, Erin finally stopped her trembling body, slowly opened her eyes, and asked cautiously.

"Of course!" Hearing that Erin seemed to be a little skeptical, Haoyi couldn't help but raise his head, patted his chest and boasted: "Although Young Master Ben's meat is not like Tang Seng, he can live forever if he eats it, but it can be regarded as the best human flesh in the world." A bite of nourishing beauty, nourishing yin and yang, strengthening the body, opening the body and increasing wisdom, etc., has many health effects, even if you can't live forever, it is enough for you to stay young and prolong your life! ”

Listening to Haoyi's advertising words, Erin first opened her mouth in surprise, and then couldn't help but cover her mouth with a puff and laugh.

"Laughing at what? Whoever eats knows it! Haoyi was very dissatisfied with Erin's laughter, stared wide-eyed to learn the advertisements on TV, and said loudly. As the words landed, Erin laughed even more, almost forgetting Shicai's fear of the roar.

"Woo......" However, at this moment, the low and gloomy roar reached the ears of the two again, making Erin's face suddenly stiffen. Syllable! Almost at the same time, the simple flashlight in Haoyi's hand was inexplicably flashed out.

"Haoyi!" Erin screamed, reached out and grabbed Haoyi's arm in a panic, and began to tremble again.

"Don't be afraid, I'm here!" Through the starry night leaking from the hole above his head, Hao Yi vaguely felt that a pair of small lantern-sized, green eyes flashed at the end of the cave in front of him. This change made Haoyi's expression solemn. However, in order not to make Erin too scared, Haoyi did not say what he saw, but gently patted Erin's fragrant shoulder and comforted her.

After a while, the lingering sound of the low roar left in the cave finally faded away, Haoyi breathed a sigh of relief, pushed away Erin, who was almost hanging around his neck, and said, "Grandma is fine, wait here, I'll get a flashlight again!" With that, Haoyi drilled into the cockpit of the locomotive again. After a round of tinkering, Haoyi came out with a flashlight made of another headlight.

"Haoyi, let's go quickly! I—I'm scared......" Although the bright headlights filled the cave again, the fear in Erin's heart still did not diminish a little. I saw her trembling and grabbing the corner of Hao Yi's clothes, secretly looking at the scene from the corner of her eye, and begging Hao Yi in a low voice.

"Okay!" Haoyi nodded, and then held a simple flashlight to take a picture of the front and back, left and right, wanting to see where the two of them fell. That simple flashlight is actually a car light directly connected to a small piece of car energy block. Although it looks strange and ugly, it is still quite practical, and it is a little brighter than the tactical flashlights issued in the army.

Under the illumination of the bright headlights, Haoyi found that the walls of the surrounding caves were like fish scales with regular chisel marks, and the cross-section of the entire cave was irregular oval, the upper part was narrow and the lower part was slightly wider, and the wide part could probably accommodate two locomotives running side by side. At the end of the car lights, there was an eerie dark shadow in front and behind, and it was difficult to see where it led. The passage above the head that leads directly to the ground is like a natural karst cave, and the exit is not high from the ground, but it is probably not less than tens of meters.

Thinking that the two of them "parachuted" from such a high place, and they were still unscathed, Hao Yi couldn't help but secretly rejoice. The locomotive on which the two of them were riding was now on all fours upside down on the slightly sour ground. Although some of the electrical system in the car is still functional, the main power engine has already emitted wisps of green smoke, which is obviously completely damaged.

Looking at the passage above his head, Hao Yi sighed lightly, knowing that it was impossible for the two of them to return to the ground the same way, so he could only follow this cave that he didn't know where to go to find another exit. Thinking of this, Haoyi found a thin cable to fix the simple flashlight of the headlights on his waist armor, and then turned out of the car and the assault rifle and ammunition that he hurriedly picked up when he was about to break through.

"Let's go, Grandma!" Haoyi clicked the rifle with a full magazine, tilting his head to Erin and said.

"Huh? Where are you going? Seeing that Haoyi seemed to be about to walk towards the end of the dark cave in the distance, Erin asked in surprise with a raised eyebrow.

"Uh, what do you say? Grandma, do you want to fly out from above? Haoyi naturally heard the fear in Erin's words, and asked with a nu mouth pointing to the passage above his head.

"I'm not an angel, how can I fly!" Erin was stunned when she heard this, pouting and complaining.

"Hehe, you're not an angel, and I'm certainly not a winged birdman. Let's go, grandma, let's walk out obediently on our feet! Haoyi tilted his head and looked at the somewhat angry Erin with interest, smiled, and then left Erin and walked towards the dark end in the distance step by step.

"Hey, Death Haoyi wait for me!" After Haoyi walked away, the darkness around suddenly surrounded Erin, and a gloomy wind blowing from nowhere faintly sent a low whistling sound, Erin subconsciously became a spirit, and was so frightened that she quickly trotted a few steps to catch up.

The two of them walked along the rugged and strange cave for a while, only to find that the walk was getting narrower and narrower. And under the walls of the cave and under the feet, there are inexplicably patches of sticky and fishy things. Under the bright light of the headlights, this kind of east and east took on a purple-red or deep purple color, covering the walls of the cave and the soil and stones on the ground like moss. Even the top of the cave was covered with such sticky things, and in some places a few strings of fishy liquid dripped from time to time.

"Haoyi, let's go back!" The cave was gradually filled with an extremely unpleasant smell, coupled with the disgusting thing under her feet, Erin couldn't help but retch, tugged at the corner of Haoyi's clothes, and pleaded softly. Unconsciously, this eldest lady, who was originally very strong, subconsciously regarded Haoyi as her only support.

"Bear with me, maybe I'll go out after a few more steps!" Feeling the "intimate contact" between the combat boots under his feet and this layer of sticky things that he had never seen before, Hao Yi was also very puzzled. Leaned down and squatted down, reached out and gently dipped the layer of liquid, put it in front of his nose and smelled it, in addition to the extreme fishy smell, there was a strange smell that stimulated the nerves and penetrated into Hao Yi's nostrils, and a feeling of dizziness suddenly appeared in Hao Yi's brain. Hao Yi was so frightened that he quickly shook off the remaining viscous liquid in his hand, and stood up in a hurry to endure the discomfort. Although he instinctively realized that Erin's suggestion was right, Haoyi still denied Erin's suggestion by mistake.

Probably out of curiosity, Hao Yi had an urge to see what it was that could make such a strange liquid.

After walking along the narrow and winding cave for a while, the viscous liquid on the ground and the cave wall became more and more, and it became thicker and thicker, and Zuihou was actually connected. The place illuminated by the bright headlights was full of purple-red or dark red liquid, and from a distance, it looked like a sea of blood in hell, making people feel sick and dizzy. What's even more frightening is that in this layer of viscous liquid, there are faint things like blood meridians, which extend along the direction of the cave and densely extend into the distance.

Erin originally begged Haoyi three times and twice, wanting him to turn back together, but after slowly getting used to the damp smell in the air and the sea of blood in front of her, the curiosity in her heart finally overcame the fear, and Erin followed Haoyi closely with wide eyes.

After turning a large bend of nearly ninety degrees, an extremely shocking picture suddenly appeared in front of the two.

In a huge cave hundreds of meters high, with no end in sight, a pyramid-like structure stands tall in the middle of the cave. Although it is also pointed, the building is significantly different from the pyramid. The pyramid was made of regular layers of stones, but the building in front of me was as if it were a natural formation, covered with uneven flesh and skin like animal scales.

At the top of the building are a pair of large, angry wolf fangs, which resemble curved chimneys and are covered with maroon animal shells, with the wolf's teeth as the center, extending from top to bottom to the ground covered with viscous liquid. On the back of the chimney and above the exit of the black hole there are white fangs that glow with a cold glow, of various sizes, but the largest is the one above the mouth of the hole.

Between these curved passages is a dark red surface like the appearance of a human heart, which is also covered with blood meridians. From a distance, the entire building resembles a pyramid-shaped heart surrounded by animal scales and tusks.

In addition to this building that made Hao Yi and the others stunned, around it, at the entrances of those curved passages, there were also sporadically towering meat balls more than half a person tall and faintly flashing with pale yellow light. The balls seemed to be fixed to the sticky, smelly liquid on the ground, crawling all over the body with dark red meridians, and three or five things like some kind of reptilian tentacles, tightly wrapping them.

"Woo ......" Just as Haoyi and the two were stunned by the shocking picture in front of them, another low and ugly roar suddenly came out of the strange building......
