The appearance of the giant monster stunned everyone. It looked like a lizard mutated by radiation in the movies, but it had no eyes at all, and its body was densely scaled, as if it was wearing a black and gold armor, and its large mouth was full of stalagmite-like sharp teeth, and the tongue protruding from its mouth was thicker and longer than the python.

No one knew where the monster had come from, but it turned its head to the snake corpse and swept away the python's remains with just a few flicks of its tongue.

After swallowing the snake meat, the monster, which was obviously unsatisfied, quickly turned its eyeless head to Nie Xiao, who was closest to him.

Nie Xiao, who didn't reveal the slightest nervous look when he was attacked by the python, couldn't help but be frightened in the face of this giant monster that suddenly appeared. He is still sane, though

His heart was beating wildly, but he still used as much brisk movement as possible to pull out the mountain knife at his waist with one hand, and waved the others with a flashlight in the other hand, signaling them to retreat quickly.

Liu Qian and Tashi both understood Nie Xiao's sign language, and quietly and decisively urged everyone to get up and run. However, as soon as everyone started to move, the monster's terrifying tongue like a meteor hammer had already ejected from his hideous mouth and flew straight towards Nie Xiao.

In the face of the surprise attack of the monster giant tongue, although Nie Xiao reacted quickly and dodged sideways, avoiding the frontal impact of the tongue, but unexpectedly, the tongue swung towards him like an iron whip and smashed it hard.

At the critical moment, Nie Xiao could only swing his knife to resist, although he barely repelled the attack of the giant tongue, but he was like slashing a steel rod, his hands were numb, and the tiger's mouth holding the knife felt like it had been torn apart, and the whole person couldn't help but be hit back several steps by that blow, and almost fell to the ground.

The monster with its wounded tongue became manic, and while letting out a giant baby's cry and slapping its giant tongue in the water, it writhed its body wildly and rampaged, causing the water in the pond to churn like a boiling storm, and the stalagmites broke at the same time, shaking the whole cave to tremble.

Nie Xiao knew that something was wrong, so he quickly turned his head and ran wildly, while the people who had already drilled into the narrow hole in front of him shouted: "Nie Xiao, run!" While witnessing the monster's giant tongue flying towards Nie Xiao again and again, constantly destroying the stalagmites and stone pillars around him, and passing by him again and again.

Fortunately, the team members were lucky, and they didn't run far, and Tashi, who was the leader, found a narrow hole that only allowed one person to bend over, and immediately led everyone to jump into it one by one.

The best thing about this cave is that it is narrow and not straight, and after jumping into the cave, the group rushed forward for about ten meters before stopping. And although the angry monster chased after the entrance of the cave and kept shooting into the cave with its terrible tongue, it was still beyond the reach of the whip, and it could not destroy the entrance of the cave and invade directly.

"No wonder the wolves don't dare to go into the hole. It's a python again, and it's a monster again. Ge Zhengtian said while panting.

"What kind of monster is that?" Wang Zhigang also gasped.

No one could answer Wang Zhigang's question, but not long after he finished speaking, the tongue attack a few meters away stopped abruptly, and the frightened students immediately began to talk.

"The monster is gone?"

"But don't you get eaten by some more terrifying monster?"

"Where could there be a more terrifying monster?"

"Maybe. The underground caverns are the weirdest place in the world, and there may be some prehistoric monsters that disappeared from the surface of the earth millions of years or hundreds of millions of years ago. ”

"Alright, alright. Scientists, don't engage in science fiction fantasies. I don't think it's good to stay here for a long time, so let's hurry up. Liu Qian saw that everyone's expressions had recovered, and immediately stopped the discussion among the students.

Although the narrow cave allowed the group to block the deadly monsters, the winding and mysterious environment inside the cave made people feel uncomfortable. After walking in this mysterious narrow hole for a while, even Yao Xi, who had a nymphomaniac attack and was excited, became like a frosted eggplant, and lost his spirit. In this oppressive space, the students even began to wonder if there was an end to this narrow hole, and began to wonder if they could get out of this bottomless cave alive.

However, just before everyone's psychology completely collapsed, the sound of running water finally began to appear in the depths of the quiet narrow hole.

As the group approached the source of the sound, the sound of the water became louder and louder, from a trickle of whispers to a roar of a torrent. That is, when they heard the sound of the mighty water, the team members were pleasantly surprised to find that they had reached the exit of the narrow hole, and outside the exit, there was the rushing underground river.

Upon further observation, it was found that the light of the flashlight could not penetrate the rushing river at all. The entrance of the narrow cave is still about two meters away from the riverbank, which is only about one meter wide below, and if you jump down, you are likely to fall into the river.

After some discussion, the team members collectively decided that Nie Xiao and Tashi would first descend to the river beach with a climbing rope to initially explore the river beach environment. If there are no problems, the graduate students will follow up one by one. And the instructor Liu Qian acted in the name of observation and guidance.

Nie Xiao and Tashi are worthy of being experienced ace special forces, and they went down to the river beach in three or two clicks, completed the exploration, and sent a signal from the team members in the cave that "you can start rappelling".

Although the walls of the river beach cave were so slippery that it was difficult to get off their feet, and the graduate students could not complete the rappelling as skillfully as Nie Xiao and Tashi, the overall process was relatively smooth. However, as soon as the team members untied Chen Peng, who was tied to the rope, from the rope, Yao Xi let out an exclamation.

Everyone responded and hurriedly shone the flashlight towards Yao Xi, but they didn't expect that just two crabs climbed onto her field boots.

Just as everyone was making a fuss about Yao Xi, Lu Nianxuan vaguely saw something lying on the river beach downstream in the light of the flashlight that swept by, where the lighting distance was close to the limit.

The strange object uneasy her, but she calmly quieted everyone and carefully shot the flashlight at the object.

With the light of the flashlight, everyone found that in the lower reaches of the dark river, the space of the entire river cave has become much larger, the river surface and river beach have also become much wider, and the river flow has slowed down significantly. However, due to the limitations of the cavern space, it is impossible to see the full picture of the underground lake.

The object that disturbed Lu Nianxuan happened to be located on the beach at the junction of the underground lake and the underground river. Due to the distance, if you are not careful, it is easy to mistake it for a rock in the river cave and ignore it. However, the team members who had just encountered the monster took a closer look and recognized that the creature lying on the shore like a huge rock was the same kind of creature that drove them into the narrow hole. To make matters worse, the creeping monster was located in a position that the team had to navigate downstream along this side of the riverbank.

Faced with such a situation, everyone discussed and decided that the athletic Nie Xiao and Tashi would go upstream to find a way out, while the other team members would return to the narrow cave first and wait for news from Nie Xiao and Tashi.

After experiencing Chen Peng, who was tied down to the beach, tied to the hole, and bumped several times in the narrow hole, the situation became more and more serious, and even Liu Qian began to worry about his safety, but in the cave, the distress device has no signal, except for finding the exit, there is no way for Chen Peng to be treated. It didn't take long for Nie Xiao and Tashi to come with new bad news: not far upstream of the dark river was a steep slope with a slope of nearly 90 degrees, the slope was nearly three meters high, and the river cave collected debts here, and the river bank disappeared, only the dark river flowed down from the hole in the slope, there was no gap for people to climb and cross, and there were no other caves along the way to pass.

In the face of the deteriorating situation, everyone fell into a heated debate about what to do. Nie Xiao, Tashi and Wang Zhigang advocated taking the risk of crossing the river from across the river to the downstream. And Lu Nianxuan, Ge Zhengtian, and Yao Xi felt that it might be safer to go back, at least they could find the exit, and after such a long time, the wolves should have left a long time ago, and returning to the original cave entrance could at least ensure that Chen Peng could be rescued.

The argument was difficult to end for a while, Lu Nianxuan was so anxious that she wanted to pull Ge Zhengtian to pick up Chen Peng and return the same way. But before he could make the trip, Yao Xi screamed again. Everyone looked at the call and saw a centipede the length of Chen Peng's arm lying on the back of Chen Peng's hand. It was too late, it was too fast, and with a swing of his sword, Tashi poked the big centipede to the ground and cut it into two sections. However, on the back of Chen Peng's hand, there was already a bloody wound.

Seeing this, Lu Nianxuan couldn't help choking and crying, and then immediately wanted to suck Chen Peng's wound with her mouth, but was stopped by Liu Qian.

When Liu Qian stopped Lu Nianxuan's unbelievable actions with a hug, Tashi immediately tied Chen Peng's bitten arm with a rope, rinsed his wound with water, and squeezed out some dirty blood for him.

I don't know if it was because of the stimulation of pain, Chen Peng, who had been in a coma for a long time, suddenly woke up and muttered: "Snake, I was bitten by a snake." ”

When Lu Nianxuan heard this, she cried even more sadly.

Ge Zhengtian comforted him with a weak heart: "It's okay." It's not toxic. You'll be fine. Don't worry. ”

Unexpectedly, Chen Peng said: "Why do you feel bitten on your hand." I remember biting it on the leg. ”

Everyone was confused by Chen Peng's words, only Liu Qian was shocked when she heard the thunder, quickly reached out and wiped Chen Peng's trouser leg tied in his military boots, and really found a blackened snake bite wound on his left calf. This wound should have been bitten through the pants, no wonder everyone has not noticed. After discovering the wound, Liu Qian quickly loosened the rope tied to Chen Peng's arm that was bitten by a centipede, and said to him with a smile, "It's okay, it's not a snake bite, it's an antidote injection for you." You relax. It'll be fine in a while. ”

Lu Nianxuan, who majored in medicine, quickly realized that Liu Qian wanted to use poison to defuse Chen Peng's snake venom. However, although centipede venom can detoxify snake venom, if the dose is not right, it is likely to aggravate the injury, but at this moment, there is no other way than to stabilize Chen Peng's mood and observe the effect of fighting poison with poison. Thinking of this, Lu Nianxuan endured the sadness in her heart, forced herself to burst into laughter, and fed the little water left in the kettle to Chen Peng.

In order to prevent Chen Peng from fainting again, Lu Nianxuan took the initiative to take him into his arms and chatted with him one sentence at a time. Tashi, on the other hand, smashed the centipede, which was still writhing on the ground, and applied its juice to Chen Peng's snake bite wound.
