The expression on his face was uncertain, Tuoba Aoyu's eyes flashed, and he made a decision in an instant, no matter what, Mu Yuyao was the way she is now in order to save herself, even if she exhausts her qi and blood, she must expel all the demonic nature in her body.

"Clansmen, your heavenly spirits will never allow me to do such a treacherous thing, forgive Ao Yu!"

The longer Tuoba Aoyu knew that the longer the Dao was delayed, the more demonic energy in Mu Yuyao's body would accumulate, and it would be more difficult to clean up when he poured, so he forcibly endured the loss of qi and blood in his body, and his red pupils activated, devouring the demonic qi in Mu Yuyao's body little by little.

Half a quarter of an hour later, there was no blood on Tuoba Aoyu's face, he gritted his teeth and persevered, and finally cleared all the demonic nature in Mu Yuyao's body, while his own body was shaky, and blood streaks appeared in the purple pupil and the right pupil that had returned to normal, which was the sequelae that appeared after the loss of qi and blood reached the extreme.

If it weren't for the majestic qi and blood of the thirty-six star realms in Tuoba Aoyu's body, coupled with the comprehension of the spirit transformation technique, and the cultivation to break through to the battle spirit realm, I am afraid that today not to mention the removal of Mu Yuyao's demonic nature, even his own survival in the demon cave, I am afraid that it will not be easy.

Clearing the demonic nature in Mu Yuyao's body, Tuoba Aoyu finally breathed a long sigh of relief in his heart, and he didn't care about the exhausted qi and blood in his body, he quietly waited for the third senior sister Mu Yuyao to wake up.

Half a sound, Mu Yuyao's willow eyebrows wrinkled slightly, and then, her cold eyes opened, and with just one glance, she saw Tuoba Aoyu's pale face, and her heart moved slightly, knowing that Tuoba Aoyu got rid of the demonic nature in her body, thus consuming the qi and blood in her body.

Looking at Tuoba Aoyu, Mu Yuyao's eyes were complicated, and her face was slightly softened, but she didn't know what to say.

"Xie Lu Xie!" The voice was weak and inaudible, like a mosquito buzzing, even Tuoba Aoyu, and he could only barely hear it.

The corners of his mouth smiled bitterly, but Tuoba Aoyu didn't dare to take credit, "If the third senior sister hadn't saved me, she wouldn't have been swept up by the demonic storm at all. ”

Mu Yuyao glanced at Tuoba Aoyu in a daze, her eyes focused on the purple pupil on the left for a moment, and she didn't say anything, and her eyes returned to coldness.

"Third Senior Sister, after I woke up, I observed the Demon Cave and found that where we were at the moment was only the entrance of the cave, and we had not penetrated into the depths of the Demon Cave at all, but if we wanted to get out, it would be difficult to estimate that it would be difficult, because there was a wind blade that tore through the space at the entrance of the cave, and unless our cultivation reached the Triple Battle Spirit Realm, it was basically impossible to get out. ”

"Moreover, in the Demon Cave, there are things that affect the pulse sense, and my pulse sense can only perceive the range of about one zhang around, and two zhang is already my current limit. ”

When Mu Yuyao heard this, her face changed slightly, and she spread out her pulse, she found that what Tuoba Aoyu said was not wrong at all, and her pulse could only perceive a range of two zhang.

Mu Yuyao has been in the sect for three years, fifteen years old, a realm double battle spirit, bloodline emperor level, and strong strength, but with her cultivation, she can only perceive the range of two zhang around, which is quite amazing, and the most surprising thing for Mu Yuyao is that Tuoba Aoyu can actually perceive the range of two zhang in the demon cave.

"What kind of bloodline is he?" a trace of doubt rose in Mu Yuyao's heart.

"You can't go out, but it's not an option to just sit here and die, be careful, let's go deeper. Mu Yuyao pondered for a while, planning to go to the depths of the demon cave to take a look and find out if there was any other way out.

At that moment, the two of them went one after the other, their pulses spread, and they cautiously walked towards the depths of the demon cave.

Tuoba Aoyu will take the initiative to avoid her because of her red pupils, but Mu Yuyao will not, Mu Yuyao's existence, like a bright light in the dark, constantly attracts demonic qi to her body, and she has no choice but to use the qi and blood in her body to arrange a defensive shield outside her body, only in this way can she resist the erosion of demonic energy, but this is obviously not a long-term solution.

In this demon cave that cannot be replenished after the consumption of qi and blood, for her, this situation is undoubtedly fatal.

However, as long as she doesn't find a way out, this situation will always exist, and she has no better way to do it, so she can only advance with Tuoba Aoyu, hoping to persevere until the moment she finds a way out.

As they continued to move forward, Mu Yuyao and Tuoba Aoyu gradually became suspicious in their hearts, and they became more and more surprised, because the demon cave seemed to be endless, and they had been walking for more than half an hour, and they still didn't have the slightest feeling of reaching the end.

In this process, Tuoba Aoyu found that whenever the qi and blood in his body were about to run out, the beast pattern outside his body would launch a glimmer of light, giving birth to a small suction force, absorbing the demonic qi floating in the demon cave, and then replenishing a small part of its energy into his body like a filter.

Slowly, the deficit of qi and blood in his body accumulated more and more, and finally there was a trace of recovery, Tuoba Aoyu was slightly happy in his heart, knowing that his qi and blood could be replenished in the demon cave, and his heart was no longer in a hurry.

"What's that sound?"

Suddenly, Mu Yuyao, who had been walking in front, paused, her ears pricked up, and she heard a strange sound, not the scream of a ghost crying wolf, but a strange sound that was breathtaking.

Tuoba Aoyu listened attentively, and then said with some uncertainty: "It seems to be... Piano sounds!"

"Well, it's a little bit like that!" Mu Yuyao nodded, her pretty face became a little more dignified, and she was extremely cautious when she walked.

After another quarter of an hour, various voices sounded in the demon cave, as if there were gods and demons singing, ghosts wailing, beasts roaring, and scenes of illusions appeared in front of the two of them.

Tuoba Aoyu's mind is the same, unmoved, his red eyes flickering, shattering all illusions.

Mu Yuyao's eyes are clear, her eyes are like electricity, everything is like an epiphany, and she leaves no trace in her heart, which is a deep realm of enlightenment, and she has penetrated all the illusions in front of her.

Tuoba Aoyu was secretly surprised in his heart, and he admired this third senior sister who was only three years older than him, this kind of method was really terrifying.

When they arrived here, bats flew up from time to time in the pitch-black demon cave, and the aura was a little more eerie than what the two had done before, and an inexplicable powerful resentment and hatred filled the demon cave, disturbing the minds of the two.

Fortunately, both of them are extraordinary people, blocking the slightest resentment and preventing them from coming.

"This resentment is so strong!" Tuoba Aoyu exclaimed.

Mu Yuyao's expression was unprecedentedly serious, staring at the front, and said softly, "Not just one share, it's many shares!"

"How many shares?" Tuoba Aoyu was startled, all he sensed was a sense of resentment, and he didn't even notice the existence of other resentment.

"Something is wrong with the situation, be careful yourself!" Mu Yuyao advised, her delicate body writhing, like a water snake, step by step towards the passage where the sound came from the demon cave.

Behind him, Tuoba Aoyu's red pupils flickered, he looked at Mu Yuyao's figure moving forward, and found that on Mu Yuyao's head, the red light and blue light accounted for half each, constantly fluctuating.

"The red light represents the great evil, the blue light represents the great luck, and the great evil and the great luck appear, what does this mean!" Tuoba Aoyu's eyebrows were tightly twisted, and his eyes were very puzzled.

Not daring to slack off, he walked a few steps quickly to keep up with Mu Yuyao.
