Looking in the direction Guo Huitong was looking, Hao Yu found that on the cliff about a dozen zhang away, under the cover of green trees and vines, there was really a cave with a black hole, which looked quite big.

"Further up here, there is no convenient way up the mountain, just go to the cave to have a look, it is just convenient for Juan'er to get rid of the demonic qi in her body. ”

The distance of more than ten zhang is nothing to Hao Yu, even if they can't fly in the air, in a jump, it is over, very soon! A few of them arrived in the cave, the first cave was Hao Yu, and he was still jumping into the cave at the moment, and he shot out to clean up the vines and branches hanging down at the entrance of the cave, so that it was convenient for his companions behind him to enter the cave.

When he entered the cave, Hao Yu found that he had underestimated the cave on the cliff, and the space here was much larger than what he saw at the entrance of the cave, and there seemed to be a larger space in the cave.

Because of the anxiety about Juan'er's injury, everyone didn't have much heart to observe the situation in the cave, Hao Yu was at the entrance of the cave, gave Juan'er luck to heal the poison, spread a large piece of clean animal skin on the ground, and put the unconscious Juan'er on the animal skin, Hao Yu reached out and put one of her arms, and then ran the Nine Extremes Exercise, after the internal breath rushed into the girl's body, he quickly inspected her internal organs, and after finding the demonic qi, he wrapped it and sent it back to Hao Yu's body, just like that! It took Hao Yu less than ten minutes to involve all the demonic qi that invaded Juan'er's internal organs into his body, and with the help of the Nine Extremes Exercises, these difficult demonic qi became his internal breath.

"Sister Juan'er, how is he?

Seeing Hao Yu standing up, Xiaohu immediately asked, until he saw Hao Yu nodding, the anxious look on his face dissipated, and joy crept into his eyes.

Guo Huitong and Fu Yuting, who had been standing on the sidelines and watching the progress of drug treatment, were also relieved, but as soon as they put their minds at ease, Guo Huitong pestered Hao Yu and asked him to teach him how to solve the demonic qi.

"It's that simple, it's great! When I encounter this kind of pesky weird energy again, I can turn it into my own energy, and I feel happy to think about it. ”

After about half an hour, Juan'er woke up, and it seemed that she had recovered well, and there was nothing wrong with it, which naturally made Hao Yu and them happy.

After a night of silence, after resting at the entrance of the cave for most of the night, Hao Yu and the five of them all recovered to their best state, even the girl Juan'er who was invaded by demonic energy, and she also looked a little weak, and the good couldn't be better.

"Are you really going to go inside and investigate? Why don't we continue to climb up from the outside?"

Hao Yu didn't have much opinion on Guo Huitong's suggestion to explore the depths of the cave, but Juan'er, who had been frightened by the black insect tide once, and Xiaohu and the two of them, didn't want to go deep into the cave, and it seemed that from the bottom of his heart, there was a fear of the darkness ahead.

"No problem! You two put on this equipment, and you can rest assured. ”

Guo Huitong did not force the two small ones to persuade them, but made their own demonstrations, equipped the combat mech, and turned himself into a steel man, so as to reassure the two small ones, sure enough, it didn't take long for the two small ones to equip themselves with a set of small mechas, and they seemed to have a lot more courage, and they no longer objected to entering the depths of the cave.

After walking through a straight tunnel about 300 meters long, and after turning a corner, Hao Yu and the others walked into a wider tunnel. What Hao Yu didn't know was that when they turned the first corner, the entrance of the cave that was originally wide open actually boomed and was blocked by a boulder falling from above the mountain wall, that is to say, if Hao Yu and the others wanted to withdraw from the direction they came from, they were afraid that it would be difficult, because the entrance of the cave had been blocked.

"Well, why is the entrance to the cave sealed? Damn! If you can't find an exit in front of you, you really can't get out. Hao Yu was the first person to find that the entrance to the cave was sealed, and he didn't think about hiding it from everyone, but said it out loud so that the four people who walked in front of him could hear it.

"What are we going to do now? We can't get out. Xiaohu's eyes, hidden under the helmet goggles, showed a little horror.

"Don't worry! With Brother Hao Yu here, we will definitely be able to get out of this cave. "Little girl Juan'er is full of confidence in Hao Yu.

"Well, with me leading the way, we will definitely be able to get out, don't worry. Guo Huitong was not a little nervous, she was at the forefront, but turned back from time to time to cheer everyone on.

At this time, Fu Yuting, who was walking behind Guo Huitong, suddenly opened her eyes and stopped: "Did you hear any strange sounds?"

"What sound? I didn't hear anything...... There's a sound coming from the front, so let's speed up. ”

When Guo Huitong ran, Hao Yu also heard clearly, in front of the cave, there was really a strange sound coming, hearing that sound, Hao Yu had a feeling of heart fluttering, as if a small drum was beating in his heart, and as they continued to go deeper into the cave, that feeling became stronger and stronger.

"I ...... I feel uncomfortable, as if there is a small drum in my heart, it is shaking, no! I want to vomit ......."

At this time, everyone's pace slowed down unconsciously, walking and walking, and Guo Huitong, who was at the forefront, suddenly leaned against the mountain wall, gasped for breath, and shouted uncomfortable, and then bowed down and retched, which seemed to be very uncomfortable.

"Hmm~ I'm so uncomfortable...... too"

"Me ...... too"

It's like a chain reaction, and within a few minutes, the other three people except Hao Yu also showed uncomfortable looks, seeing them bending down and retching one by one, Hao Yu frowned, after arriving at this position, he actually felt very uncomfortable in his heart, but it may be that his skills are higher, and it is not as obvious as the few companions who walked in front.

"Why don't you all go into the Crystal Soul Tower to rest, and now we can only continue to move forward, but you ...... like this"

Hao Yu's words, before he finished speaking, he vaguely heard that from the dark passage in front of him, there was a tom-tom-tom, like a drum-like sound, at this moment! The voice was very clear, and when he heard this sound, Hao Yu's face changed suddenly, he snorted, and almost vomited on the spot.

"What's up ahead?"

Hao Yu's face turned slightly pale, and he raised his eyes to look into the depths of the darkness, his brows furrowed even deeper, and he muttered in his heart.
