Yi Feng was on top, Qinghua was in the middle, Tang Shuxing was at the end, and the three of them maintained three positions, upper, middle and lower, and climbed from the sinkhole wall to the upper end. In the process of climbing, when Tang Shuxing caught those small holes used to climb, he knew that the alien blood clan who dug out these caves earlier had spent a lot of effort, not to mention, they were also filled with some kind of fixed substance one by one, although he didn't know what it was, but because of that substance, he put his hands and feet in it, and he wouldn't feel soft after stepping into it.

Later, Yi Feng told the Tang Shu Punishment that that substance was a secretion from the eyes of the alien race, and if you insisted on comparing this secretion with that of humans, it could only be regarded as eye feces.

Tang Shuxing crawled for a while, looked up at the upper end of the sinkhole, and found that the distance was still very far, so he simply rested against the wall, and said in a low voice: "Yifeng, rest, climb later, I'm afraid that the blue and white will not be able to bear it." ”

As soon as the words fell, Qinghua sighed: "Rest, I really can't hold it anymore, my weight is the sum of the two of you." ”

Yi Feng actually climbed down from it upside down at this time, climbed between the two and said: "This has nothing to do with weight, the main thing is to see how the limbs are coordinated, you are just too afraid, that's all, don't be afraid, step on it steadily, reach out and grasp it steadily, it must be no problem." ”

"It's easy to say." Qinghua muttered, and as soon as she finished muttering, her face changed, and she looked down and said, "Did you hear that?" ”

"What?" Tang Shuxing and Yi Feng asked almost in unison, because they hadn't heard anything.

Qinghua looked down tremblingly, but because of his large size. With a big head, he was forced to fall backwards as soon as he lowered his head, and after almost slipping down, he clung to the cave wall and said, "There's something down there, making a 'grunting' sound like something swallowing saliva." ”

Tang Shuxing and Yi Feng looked at each other, and they both shook their heads to indicate that they hadn't heard anything.

"There's really something, you believe me." After Qinghua finished speaking, she gritted her teeth and said, "Climb, hurry up!" How long do we still have to climb? ”

Yifeng hung there. Calculated: "At the current rate." It takes at least forty-five minutes and more than an hour at most. ”

Qinghua's face turned white, but at this time, he heard the voice below again, and immediately said, "No matter." Climb it! ”

Tang Shuxing shook his head. I feel that Qinghua's courage is too small. I really don't know why such a person is an alien race, the bears and werewolves and other alien races he has seen are very brutal, and Qinghua is simply an alien race among aliens.

The three of them continued to crawl forward. Not ten minutes later, Qinghua said again: "I hear it again, and it's getting closer, really!" ”

Tang Shuxing looked at Qinghua and felt that he didn't seem to be lying, and he wasn't a trickster either, because telling such a lie wouldn't do him any good - they were already in danger.

"Yifeng, stop, let's listen carefully." Tang Shuxing said.

After Tang Shuxing finished speaking, Qinghua immediately objected: "Don't!" Don't stop! Keep going! Saying that, Qinghua sped up the speed of climbing on his own, he was so tired that he was panting, and his limbs were trembling constantly, and he didn't know whether he was tired or scared.

"Then you just shut up! Keep climbing upwards! Tang Shuxing said, and also sped up.

After crawling for a while, the bottom of the cave below suddenly made a "grunting" sound, which was small at first, and then became larger, as if the whole hole was a trumpet, and when the sound came to their place, they could fully feel the vibration of the sound waves, and the corners of their clothes were rolled up.

"Now! At! You! Guys! Listen! Arrive! Finish! Let's do it! Qinghua shouted.

Tang Shuxing and Yi Feng above were clinging to the wall, not daring to relax at all, and they couldn't answer Qinghua's words.

The sound waves passed by where they were for a full minute, and then rushed towards the top of the sinkhole.

After the sound wave passed, Tang Shuxing immediately said: "Don't climb anymore!" Stop it! This sound is sure to alarm the soldiers above! ”

Yi Feng turned his head and said: "There is only one such road, if we don't climb it, we will die, in case they use a strong light to shine down, they will also find us!" ”

Tang Shuxing looked down, then looked up, and then said: "Stop for a while, wait, wait for that sound wave to reach the top of the sinkhole, and see the situation, if you climb again, it will be closer to the entrance of the cave, and they don't need night vision goggles to see us!" ”

Yi Feng nodded, and could only agree with Tang Shuxing's opinion.

The three of them waited there, looking up, and after a long time, until the lights flickered above, and they also knew that the sound wave had reached the top, and it caught the attention of the soldiers, and they began to look down.

"Here we go again!" Qinghua said at this time, he heard the grunt sound again, and his sensitivity to this sound was higher than that of Tang Shuxing and Yi Feng.

"Great!" Tang Shuxing seemed very happy, and immediately clung to the wall, and this time the sound wave came faster than the last time, and soon passed in their direction, reaching the top with a rapid speed, and then a ball of light fell from above, and at the same time, a scream was heard, and it sounded like there was more than one person.

Then, the light fell to the location of Tang Shuxing and the others, Yi Feng's eyes were quick, and he grabbed the flashlight in his hand with a whirlwind, and then turned it off, and the light of the flashlight shook past, roughly illuminating the fallen soldiers - at least 4 people.

"This sound wave is somewhat aggressive, at least it can produce vibrations." Tang Shuxing raised his head and said, "Now you can climb, it seems that the frequency of the sound wave will be faster and faster, and the speed will be faster and faster, this thing can also cover us, as long as this thing is there, the soldiers outside the sinkhole dare not approach lightly." ”

"But......" Qinghua said below, "but what if they stand far away from the sinkhole and wait?" Or do they have snipers on target? ”

"It's not a sinkhole! They can't keep an eye on it, and they only have searchlights, no large lighting sources around! Therefore, even if the searchlight is shaking, it cannot shine on us so coincidentally! Tang Shuxing looked at Qinghua, "Can you have a little backbone?" Like a man! ”

Qinghua pondered for a long time and shook her head vigorously.

"! Do you believe it or not, Lao Tzu kicked you down!? Tang Shu scolded and said to Yi Feng above, "Keep climbing!" ”

Yi Feng's speed is fast enough, Tang Shuxing is chasing after him, only Qinghua is the slower, after all, he is a foreign race, in fact, he is not tired, but because he is afraid in his heart, he is too afraid of death.

Finally, the three of them were still dozens of meters away from reaching the entrance of the cave, during which they had already experienced ten sonic attacks, and they could no longer see soldiers stationed at the edge of the sinkhole.

"Quiet! Now is the most critical moment, we have to take advantage of the next wave of sound waves, use the thrust of sound waves to send us up, but we can only go forward about ten meters at a time, everyone pay attention to the small hole in the wall of the cave at any time! Tang Shuxing said in a low voice.

"Understood!" Yi Feng responded, but Qinghua did not respond for a long time.

"Blue and white! Are you dead or not? If you don't speak, I won't care about you later! Tang Shuxing shouted.

Qinghua didn't answer, but the person was still there, Tang Shuxing lowered his head, and found that Qinghua's whole person was sticking to that motionless, just as he was about to go down and step on Qinghua with his foot, he saw something on the left and right sides of Qinghua, he immediately waved his hand and touched Yifeng's ankle, and said in a low voice: "Give me the flashlight, quick!" ”

Yi Feng threw it down and admonished: "Turn on the flashlight at this distance, it is easy to be discovered!" ”

"Looks like there's something down there." Tang Shuxing explained, "It's on both sides of the blue and white flowers. ”

After Tang Shuxing finished speaking, he turned on the flashlight, but it only flashed, but it only flashed like this, but it made him gasp, and he saw clearly, on both sides of the blue and white were the kind of worms he had seen in the forbidden land of the Shiva clan in the Gu hunting ground, but the two were not too huge, twice as big as an adult tiger.

The moment Tang Shuxing turned on the flashlight, Yi Feng also saw it clearly, took a breath, and asked, "That's the kind of thing you said and might have seen?" Is it a bug that digs out a burrow? ”

"It should be." Tang Shuxing nodded and said, "Qinghua is stupid now, I don't dare to leave, I can't leave him." ”

As he spoke, Tang Shuxing crawled down and stepped on Qinghua's head with his foot, and Qinghua quickly took out his hand to grab his ankle.

Tang Shuxing said in a low voice: "Qinghua, pluck up your courage and climb up like a man, those things won't bite, you just treat them as if they don't exist at all!" ”

Qinghua just shook Tang Shuxing's ankle, indicating that she couldn't help it.

Tang Shuxing was almost desperate, and he really wanted to leave directly regardless of this kid, but since he was here, he couldn't abandon him again, so he crawled back and fixed himself at the position closest to Qinghua, and said in a low voice: "Qinghua, do you have any wishes?" ”

"Yes!" Qinghua immediately said.

"What is it?" Tang Shuxing thought that there was hope, "You think about your wishes, you have to live to fulfill your wishes." ”

"But my wish is to crawl out of here alive!" Qinghua's voice was crying.

"Fuck you!" Tang Shuxing really almost stepped on it, "You can't go!" If you don't leave, I'll make up for it and give you a ride! Saying that, Tang Shuxing really stepped on it hard, and now Qinghua panicked and was forced to start climbing towards it, while Tang Shuxing kept staring at him, giving up his position, letting him climb in the middle, and he broke off himself.

Qinghua finally climbed up, but at this time, the accident also happened, and the insects began to crawl, and at the same time, the sound waves began to impact from below!

"That's it! Get ready! When Sonic arrived, we let go and let Sonic give us a ride, but remember, we could only be ten meters away! Tang Shuxing said, feeling his feet underneath, and finally waited until the sound wave touched his ankle, and then he immediately let go and said, "Let go!" ”

The three of them let go at the same time, and Qinghua closed her eyes and gritted her teeth.

Sonic slammed into them, pushing them upwards, but the most terrifying thing was that the bugs chose the same way as them, and also let go of the wall, allowing Sonic to rush upwards against their bodies!

"Enough! Catch! Seeing that the situation was not good, Tang Shuxing immediately reached out and grabbed the cave wall, and the other two also grabbed it as instructed.

While the three of them fixed their bodies, they saw that the insects rushed straight to the top of the sinkhole with the sound waves...... (To be continued......)
