Yu Fei and the others walked towards the blood-red aura mist, and as soon as they entered the blood-red aura mist, Yu Fei suddenly felt that the blood-red aura was constantly drilling into his body through the pores on his body. Feeling this scene, Yu Fei's face couldn't help but change slightly, and he looked at Wu Changxiao on the side, but Wu Changxiao's face didn't show any unusual looks, seeing this scene, Yu Fei couldn't help but wonder in his heart, didn't Wu Changxiao feel it?

Yu Fei looked at Wu Changxiao beside him and asked, "Brother Yu, do you feel that something is wrong in this blood-red aura, this strange aura can penetrate into people's bodies!"

Hearing Yu Fei's words, Wu Changxiao's expression was obviously stunned, and he felt the surrounding aura with a puzzled face, but did not find that the surrounding aura drilled into his body, Wu Changxiao couldn't help but shake his head and said: "No! I didn't feel them coming into my body, but I felt that the aura in my body seemed to be extremely repulsive to this blood-red aura fluctuation! As soon as they get close to me, the aura in my body will drive them out at an extremely fast speed! Could it be that this blood-red aura is drilling into your body?"

Yu Fei nodded, and seeing Yu Fei nodding, Wu Chang Short's face suddenly showed a shocked look, and he hurriedly asked, "Do you feel anything wrong?" This blood-red aura was filled with a large amount of violent power, and after it was absorbed by the cultivator, this violent power was extremely difficult to refine, and it was easy for it to go wrong in future cultivation. Yu Fei felt it slightly and shook his head, he couldn't help but feel the discomfort coming from his body, and even felt that the Yuan Infant who had been sleeping in the dantian for a long time actually took the initiative to absorb the blood-red aura around him, and even the aura in his body began to grow slowly.

Yu Fei didn't know whether this situation was good or bad, since his strength broke through to the late stage of the Tribulation, no matter how he cultivated, the aura he absorbed was like a stone sinking into the sea, without any movement, but now he actually began to take the initiative to absorb this blood-red aura! As this blood-red aura continued to enter his body, Tongtianzang began to operate automatically, and streams of blood-red aura continued to pour into his body. Seeing this scene, Yu Fei was shocked in his heart, it was too late for him to stop it, only to see a large amount of blood-red aura enveloping his Yuan Infant, and a stream of aura was devoured by Yuan Infant.

Seeing this, Yu Fei's heart sank suddenly, and he didn't know whether he was happy or sad when he saw this situation. Wu Changxiao was also shocked when he saw this scene, but he was relieved when he saw that Yu Fei had not changed much. After feeling it for a while, Yu Fei saw that there was no accident in his body, so he didn't pay attention to this change, and it was not a bad thing for him to be able to absorb this blood-red aura! Immediately, Yu Fei didn't pay attention to the changes in his body, and flew directly inward with Wu Changxiao.

However, because of this blood-red aura, the visibility is very low, and the range of the spiritual consciousness released is within dozens of miles, so the flight speed of the two is very slow! After all, with the current cultivation of the two of them, the distance of dozens of miles is only a matter of a few breaths, in case of any emergency, even if the two of them are given time to react, it is not enough! In this way, the two of them flew in this blood-red aura in the sky for a long time, and the more they went inside, the thicker this blood-red mist became, and even at the end, they could feel the existence of this blood-red aura. And Yu Fei's cultivation has also grown a little bit because of the continuous absorption of this blood-red aura. Although this small section is insignificant to Yu Fei now, Yu Fei is sure that if he allows himself to cultivate here for a period of time, he is afraid that he will be able to cultivate to the point of breaking through the Mahayana period, but he does not have enough time right now.

Holding back the momentum in their hearts that they wanted to sit down and cultivate, the two of them kept flying forward, and when the two of them gradually approached the middle ground, a strong aura fluctuation suddenly emanated from the front. When this aura fluctuation emanated, Yu Fei and Wu Changxiao both felt it, glanced at each other, and flew directly and quickly in front of them, the more they flew forward, the stronger the aura fluctuation became, until they were less than a few dozen meters away from that aura fluctuation, Yu Fei obviously felt an extremely strong sense of depression. This feeling of suppression, Yu Fei had only felt in Li Lao's body.

Holding back the uncomfortable feeling in their hearts, Yu Fei and Wu Changxiao penetrated the blood-colored aura and came to the place that emitted breath fluctuations, and when Yu Fei and the two saw the situation in front of them, their faces showed shocked looks, and their eyes widened as they looked at the incredible scene below.

I saw that under the diagonal in front of the two of them, piles of white bones were piled up into a mountain, surrounded by blood-red aura, and the oppressive aura fluctuations came from the mountains of white bones in front of them. These white bones in front of him, some of them are huge, and the size of the walking is slightly smaller, but it is not difficult to see that these are the bones of the dead big demons! It's just that the most shocking thing is that the bones of the undead big demons are the most undead bones in the mountains of bones, but the bones of human beings! One by one, they are stacked together at random, and after a little feeling, the weakest breath fluctuations emanating from these bones are all the breath fluctuations of the Great Luo Golden Immortal, and even many of them have reached the late stage of the Great Luo Golden Immortal!

The corpses of tens of thousands of Da Luo Jin Immortal powerhouses were piled up here so casually, and it was hard for Yu Fei to imagine what kind of picture it was! In the immortal world, it was not uncommon for a strong person at the level of a Golden Immortal to be seen, but a strong person of a Da Luo Jin Immortal was definitely rare! If he could cultivate to the level of a Da Luo Jin Immortal, he was already a figure of an ancestor, and even if he did not start a sect, it would be the target of a party's forces to try his best to win over! And the bones of the tens of thousands of Da Luo Jin Immortals in front of him were discarded here, it was hard to imagine how terrifying the Cloud Mist Sea was tens of thousands of years ago! And Yu Fei suspects that this is very likely to be just the tip of the iceberg in this middle layer, and the number is likely to be even more!

Moreover, there are at least tens of thousands of bones in front of him, which is still the most conservative estimate! It's just that because the bones of the big demon's corpse are too big, it is more conspicuous. The two of them endured the unrest in their hearts, and slowly leaned towards the mountain of bones piled up below, and as their bodies descended further, the more they felt the aura fluctuations emanating from the bones became.

When the two of them were completely close to the skeletons below, they clearly saw that a trace of blood-red aura was emanating from these bones, and feeling this scene, Yu Fei's face became extremely ugly! Panting, staring at the blood-red aura around him, he felt that this blood-red aura was detached from those dead bones! At this moment, Yu Fei suddenly remembered what Li Rong had told him. The Li people can't stay outside for too long, otherwise the essence and blood in their bodies will be drained alive! Thinking of this, Yu Fei's expression suddenly became gloomy, no wonder he still wondered where these extremely pure blood-red aura came from!

The aura that has been tempered countless times by the body is naturally extremely pure, and the violent power mixed in the blood-red aura is not difficult to explain, the big demon originally belongs to the spirit beast lineage, and the level may be much higher than the spirit beast. The aura in the spirit beast's body was full of violent power, and the corpse of the great demon was naturally no exception! At this time, Wu Changxiao's face also showed a look of shock, looking at this scene with an ugly expression, and couldn't help but ask: "Brother Yu, could it be that these aura are refined by the so-called formation?"

Yu Fei nodded, and then, Wu Chang's voice sounded again, as if he was talking to himself: "Then what are they using to refine so much aura? Hearing Wu Changxiao's words that seemed to be talking to himself, Yu Fei looked up at Wu Changxiao fiercely, the expression on his face gradually became solemn, and an extremely absurd thought came out of Yu Fei's heart.

Slaughter!Formation!Stripping Essence and Blood!Absorption!Unprovoked Existence!Every word that everyone Yu Fei said quickly appeared around Yu Fei at this time, and these words quickly formed an extremely terrifying time in Yu Fei's mind. First, a large number of slaughters, and then a formation was laid out, stripping out the essence and aura in his flesh and blood, and using it for cultivation! Wu Chang's words just reminded Yu Fei that this was cultivation! Thinking of this, Yu Fei couldn't help but clench his fists tightly, what kind of person is it, cultivation will take such an extreme way, and it is also the root of countless people's lives as the source of spiritual energy!

At this time, Yu Fei finally understood that Li Lao tried his best to persuade himself not to provoke that force, and it was really not Li Lao who intimidated himself, just such an earth-shattering method, I am afraid that it would be very human to arrange it! However, I don't know if this strength will be the Ghost Sect? Yu Fei is not sure whether this is the handiwork of the Ghost Sect at this time, if this is the handiwork of the Ghost Sect, wouldn't the Ghost Sect have already claimed the king and hegemony in this immortal world? I'm afraid, even if it is the Immortal Emperor, he can't arrange such a big hand, right?

Looking at the blood-red aura around him and understanding the source of this blood-red aura, Yu Fei suddenly lost interest in cultivating, and even felt a little nauseous. A wave of anger in his heart may be jumped up at any time, and holding back the anger in his heart, Yu Fei flew into the distance, activated the aura in his body, and slammed into the ground. As the violent aura fluctuations fell, it suddenly brought up a large amount of dirt, splashing into the bones piled up, covering those bones. And Wu Changxiao, who was also in shock just now, also came back to his senses because of Yu Fei's movements, and cooperated with Yu Fei to blast to the ground and kick off a large amount of dirt.

As the two of them continued to work hard, the mountain of bones here was completely covered with mud, and the original blood-red aura in the sky was also reduced a lot because the mountain of bones was covered. Just when the two of them breathed a sigh of relief, a cold feeling suddenly surged into Yu Fei's heart, feeling this cold breath, Yu Fei's face changed suddenly, and his body instantly tensed. Unleashed his spiritual sense and quickly probed around, and at this moment, a cold aura quickly leaned towards the side where Yu Fei and the others were.

At the same time, a burst of mad laughter came.

"Giggles, hehehe......"

Hearing this terrible laughter, the hairs on Yu Fei's body instantly stood up, and he turned his head sharply and shouted in a deep voice: "Who?"

I saw the corner of my eye, and I caught a glimpse of a figure faintly in the blood-red aura not far away!
