"You can actually let two martial artists at the peak of the first realm and Xuan Xiu use their guns? It seems that there is danger in this cave!" I don't know where I picked a few red fruits, and when I bit them, they were sweet and sour, so I crossed my feet, lazily leaned against the trunk of the tree and glanced at the camp in the distance, observing the movement of the four bodyguards.

A few minutes later, a burst of gunfire rang out again in the cave, Zhou Hao raised his eyebrows, sat up from the trunk of the tree, and slowly climbed down without the slightest sound.

Looking at several armed bodyguards with night vision devices in the distance, he estimated the distance, picked up a few stones from the ground, and then slammed them out in one direction.

Syllable!

Smack!

Several piercing screams fell into the ears of several bodyguards through the rain curtain, and the five bodyguards, who were already frightened by the gunfire in the cave, exclaimed at the same time: "Who!"

They turned their heads in the direction of the sound.

Immediately after hearing the dense sound of footsteps stepping on the water, Zhou Hao rushed out in place at the moment when several people turned their heads, and rushed towards the dark hole at a speed several minutes faster than the cheetah, a distance of hundreds of meters, and passed through it at a rapid speed only in a breath. When the bodyguard who was close to the mouth rushed out a few steps to react, he only saw a black afterimage that could be integrated into the mouth of the pitch-black hole.

At this time, the rest of the companions, who found nothing unusual, trotted over and asked, "What did you find?"

The bodyguard looked at the dark entrance of the cave, pondered for a moment, and slowly shook his head: "No." What about you guys, what was it just now?"

"It's just a landslide on the mountain. A few stones fell. ”

When Zhou Hao rushed into the cave, in the air, he immediately noticed the smell of blood in the air, and looked vigilantly into the distance, under the faint light, it seemed like a giant python crawling!

Zhou Hao was sure that he was not mistaken, with the peak of his external strength, there was indeed a huge python with an adult's thick waist crawling not far away!

Standing in front of the snake's body, the huge head the size of a desk was split, Bai Huahua's brains were sprinkled all over the ground, his eyes narrowed, and Zhou Hao, who had seen this kind of creature for the first time, felt the vitality of heaven and earth that was more intense than the outside, took a deep breath, stabilized his mind, was on guard, and continued to walk towards the cave with blood stains.

After going about 100 meters deeper, the cave space at this moment was enough to accommodate four or five earthmoving carts side by side, and seeing a black snake corpse that was slightly larger than the outside again, Zhou Hao's expression became more and more solemn.

Because next to this snake body, a bodyguard had a distorted face, and his flesh and blood fell in a pool of blood.

He took off the night vision device above the bodyguard's head, looked at the huge cave like a karst cave in front of him, stuck to the wall, and followed lightly. On the ground, the white bones that can be seen everywhere, broken limbs and broken arms, there is an indescribable horror, and Zhou Hao's scalp is numb for a while. In the meantime, several human bones were also found, and it was thought that these two black snakes were not good.

After walking for about 500 meters, the huge cave began to slowly narrow, at this time, if there was no night vision device, it was impossible to see the surrounding scene clearly, and in my ears, I gradually heard the voices of the people in front of me, as if I was stopped by something.

Vaguely, he seemed to hear the sound of the water, endured the hot and smelly air, hid behind a rock, and his colleagues also listened to the voices of several people less than a hundred meters in front of him.

"There's water down there?"

It was Luo Cheng who spoke, and Zhou Hao still remembered his voice. On the side, someone quickly replied: "Listening to the sound of the stone falling just now, it shouldn't be too high down here." ”

Several people discussed for a while, and finally decided that the remaining three bodyguards would guard it, and the remaining four would go down the rope.

Zhou Hao was so happy that after the sound of the rope sliding, Zhou Hao, who was holding a small pebble in his hand, quickly got up, but in the blink of an eye, he locked the position of the three people, and with a wave of one hand, the three gun-wielding bodyguards who had not had time to shout fell to the ground.

When I walked forward, I found a huge hole in the stone not far away, two steel ropes were firmly fixed on the ground, and I leaned forward, and four very small lights scanned back and forth under the hole, so that I could see the scene under the pit more or less.

The bottom of the almost circular crater, a flat, craggy cliff, without a rope can not go down at all, about the bottom of the pit the size of two football fields, across a small stream, the sound of flowing water is the stream coming out, on the east side of the pothole, is a small pond.

Other than that, there doesn't seem to be anything else, and the whole cavern is over.

Squatting on the cave and watching everything that happened below, suddenly, I heard Luo Cheng say, "Look, there is a small cave here. Inside, it looks like a room?"

At the same time, at the root of the wall in the distance, under the searchlight of the martial artist and Xuan Xiu, a pile of white bones suddenly appeared, and at this time, the two of them were squatting in front of the pile of white bones rummaging for something.

When Luo Cheng and Lin Xiao'er came out of that small cave, Luo Cheng had an extra book in his hand, and when he looked at it from a distance, he didn't know what it was. From afar, I can only hear what appears to be this note.

"It's strange, that pile of human bones, at least no less than a hundred. The costumes are different, judging from the wear, there are not only the standard military uniforms of Japan in the last century, but also the clothing of our ancestors in the Republic of China. ”

"There are still a few white bones in the distance, scattered and scattered, some foreign and some domestic. Even ......" Holding a flashlight in the distance, Wang Hongxin continued in a low voice: "It's the clothing and utensils of modern people. ”

At this time, Pei Wu and Wang Hongxin had more props collected from the bottom of the pothole, including old millet rifles, ropes, old-fashioned flashlights from the last century, and some costumes of unknown origin.

Similarly, Wang Hongxin also has two extra notebooks in his hand, but compared with the one in Luo Cheng's hand, what is recorded in his hand is in Chinese, but what is recorded in Luo Cheng's hand is in Japanese language.

Luo Cheng glanced around, frowned slightly, and said, "Obviously, the Heaven and Earth Yuan Power here is very strong, but why, there is also a strong death qi at the same time?"

On the other side, Wang Hongxin obviously noticed it, looked up at the huge pothole, and added: "To be precise, the east side of the creek is abundant heaven and earth vitality, while the west side is rich dead qi. As soon as I came down, I sensed this choking breath of death. ”

The stream flows from north to south, shaped like an hourglass, wide on both sides and extremely narrow in the middle. said: "This seems to be a formation?"

Luo Cheng sighed and said: "The gourd has hydration yin and yang, and life and death are on both sides. If memory serves, this pattern should be the legendary Yin Yang Gourd Array. ”

After speaking, Luo Cheng raised his flashlight to shine on the pit wall, and then, in the middle of the pit cliff, he found a raised stone pile, and said excitedly: "This protruding thing should be the foundation of this formation." And on this wall, there should be nine such formations. ”

Wang Hongxin looked at Luo Cheng approvingly, looked around, and sure enough, he saw that there were nine identical stone piles on the wall of the pit, about the size of a person, and they came out of the wall very abruptly.

Looking at the booklet in his hand, Luo Cheng continued: "It's just a long time ago, so the formation has gradually lost its effectiveness. That's why we're here safe and sound. ”

Then he turned the conversation, looked at the notes in his hand and mocked: "Unexpectedly, what Unit 731 was stationed here before." Wait, no, it's not Unit 731 that's stationed here, it's Unit 631!"

Pei Wu and Wang Hongxin lost their voices: "631, the predecessor of the Japanese Ability Group, Unit 631?"

Luo Cheng, who could read some Japanese characters, quickly flipped through the notebook in his hand, and at the same time, Pei Wu and Wang Hongxin also hurriedly glanced at the notes in their hands.

A few minutes later, the three of them turned their faces ugly, and they all turned their heads to the pond not far away, strange, incomprehensible, and even jealous and frightened!

For some reason, Lin Xiao'er, who was wearing a gas mask, looked at the three of them and didn't speak, and asked in a low voice, "What's wrong?"

Luo Cheng just whispered: "Unit 631 has been wiped out by two groups here. Thirty-three people in total. ”

Wang Hongxin also said with some disbelief: "In the 50s and 70s of the last century, six groups of explorers came here, and all of them became bones on the ground. Halfway through his words, Wang Hongxin exclaimed, "No! Let's go quickly! Don't care about any treasures!"

Pei Wu said dryly: "I think, we can't go." ”

At this moment, the bottom of the pit trembled slightly, and a strong wind blew on the originally flat concealed ground, and then the ground began to crumble, and the stream that lay in the middle like a slender gourd also rolled, only to hear a puff, puff, like the sound of a needle and thread piercing a cotton cloth, mixed with a scalp-numbing crunch from all directions.

After just a few breaths, countless black worms the size of fingernails sprung up on the floor in front of the four of them!

Densely drilled out of the ground, Wang Hongxin pinched out the Dao Dao method with both hands and bombarded the ground, Luo Cheng's face was pale, and several fireball talismans were smashed in all directions indiscriminately.

Looking at this creepy scene, Lin Xiao'er, who was already pale, almost collapsed to the ground and was held by Pei Wu.

"What the hell are these things!" Pei Wu, who was holding Lin Xiao'er, stepped on the small insect on the ground, waved the long knife in his hand, and looked at Luo Cheng.

The latter shook his head slightly, and said strangely: "Like, it's just an ordinary beetle?"

"Beetle, your grandma, can an ordinary Beetle drill through such a hard rock?"

Wang Hongxin, who had an extra long sword in his hand, also had a numb scalp and shouted: "Don't talk nonsense, hurry up and kill these insects!"

The scene was chaotic for a while, and the place where the four of them stood at this time was the east side of the creek with plenty of vitality, and there seemed to be endless insects in front of them, babbling and babbling from all directions, and when one wave died, the next wave rushed towards the four people who were not afraid of death, forcing everyone to retreat to the middle of the narrow mouth of the stream, and shrink to face the attack of the swarm at a time.

Fortunately, Wang Hongxin and Luo Cheng reacted properly, these insects were indeed afraid of flames, and under the full bombardment of the two, they gradually formed an arc-shaped line of fire in front of the four of them, which could block the swarming insects that were constantly surging out.

Pei Wu shouted in a rough voice: "Damn, where the hell did these bugs come from!"

Lin Xiao'er, who was protected by the three of them, screamed loudly again, piercing the nerves of the three people, turned his head to look behind him, on the other side of the stream, I don't know when thousands of dense black long snakes with thick arms drilled out, one by one raised their upper bodies and spit scarlet letters.
