It's just that whether it was the first few times he came in, he had already seen the clues, or he had discovered the method of cracking the ban in a short period of time today, it was certain that Yi Yunfei knew the formation and the ban in addition to cultivation and talisman seals.

After such a long period of contact between the people of the four sixth-level sects, many things about Yi Yunzong are no longer absolute secrets to them, at least they know that Yi Yunfei is only sixteen years old now, and he has just turned sixteen years old.

A sixteen-year-old boy, even if he started learning these things in his mother's womb, he would probably only be able to master a little bit of the skin! But Yi Yunfei was in these aspects, which point was the skin? Fu Seal, Wan Fu Sect's instantaneous Fu Seal for hundreds of years in the blink of an eye, he made it in just half a year. And the prohibition and formation are very cumbersome things in themselves, and I didn't expect him to be able to practice to such a point.

The sect masters of the four sixth-level sects were more shocked than the others, and compared to ordinary disciples, these four people knew more in detail. They knew that Yi Yunfei really embarked on the path of cultivation just over half a year ago, that is to say, in just half a year, he had done something that many people could not do in a lifetime. Many people only saw his cultivation, only saw the magic of the instantaneous talisman, and only saw his insight, but they ignored the most eye-catching thing in front of them, that is, the Yiyun Sect of Nuoda.

Half a year ago, Yi Yunzong was just a ninth-level sect that couldn't even keep the sect, and the people who could be used in the sect were all a group of half-grown children in the Qi Induction Realm, and just half a year later, even the four sixth-level sects didn't dare to act rashly against Yi Yunzong, which was even more difficult than those who cultivated for those insights.

With Yi Yunfei's addition, the ban was also easy to break, and after a short moment, the invisible and untouchable diaphragm at the entrance of the pitch-black cave slowly disappeared. Everyone cheered, and the eyes of the four sect masters of the sixth-level sects looking at Yi Yunfei were also very complicated.

The entrance of the dark cave seems to be a terrifying black hole, before the ban was broken just now, it was still silent, and after the ban was broken at this moment, there were bursts of terrible sounds from the depths of the passage, this sound was like the howl of a demon, and the scream of a sudden sword breaking through the air.

Yi Yunfei hadn't moved yet, and Wang Jingnan of the Famous Sword Sect had already led his disciples to the passage first.

Because of the lighting of the torches, the passage is visible, and under the light of the torches, everyone can even see a faint dark red light on the four walls, and these dark red lights are reflected by the light of the torches, so that the passage is shrouded in this dark red hue. This dark red color, as if it was dry bloodstains, is a little weird, a little weird, and some unsettling.

The breath flowed in the passage, and there was a majestic wind blowing from time to time, and the wind carried the smell of earth, but everyone was more willing to believe that it was the smell of blood. In fact, along the way, nothing very strange happened, everything was just everyone's speculation, but everyone was still in a very heavy mood. I always feel that this road will not be so smooth.

The damp air flow was blowing on everyone's faces, and I don't know if it was the reason for this airflow, or if the fine beads of sweat that oozed after everyone was too nervous had already soaked their clothes, and many disciples felt bursts of heat, and it was very uncomfortable to cling to the wet sticking to their bodies.

"Huh!" Yi Yunfei's ears moved slightly, as if he heard a sound of breaking the air, and as soon as he raised his hand, everyone behind him stopped in their footsteps, looking around nervously. The sound of breaking the air was very soft, only Yi Yunfei heard it, and the others did not feel anything abnormal, and soon everyone looked at Yi Yunfei with inquiring eyes.

"Everyone be careful!" Yi Yunfei didn't say, and continued to move forward after explaining.

And at this moment, except for Yi Yun Sect, other sects all have disciples exploring the way ahead, protecting important people in the middle. As for Yi Yunzong, Yi Yunfei was at the forefront, Li Hu and Zhao Yu, as well as Xu Ruyun and other Xiao Xingyun, accelerated in front of Yi Yunfei several times, hoping to protect Yi Yunfei like other sects, but he stopped him.

"The time has not yet come for you to protect me, I am your nanny now, and when you can really support the overall situation, crying and begging me, I don't bother to care about you!" Yi Yunfei laughed and said disapprerovingly.

The disciples of Yi Yunzong behind him looked at Yi Yunfei's not broad shoulders and his straight body like a javelin, and only felt that this young man seemed to be the tallest man in the world.

The distance from which the light of the torch can illuminate is not too far, and most of the disciples of the several major sects are cultivators above the Xuan level, and almost all of them release divine thoughts and sense the distance. However, this space is indeed weird, and it seems to have a suppressive effect on the divine thoughts, even under such an astonishing situation as Yi Yunfei's divine thoughts, they can only disperse a short distance of more than ten meters, and the consumption is huge, as if they are moving forward in the viscous mud.

After advancing for two or three miles, except for the dark red cave wall, everyone found nothing, and there was no more obstruction such as prohibition, but it was quite smooth, but everyone almost did not make any sound, and the atmosphere was very depressing. No one knew what to say, no one was in the mood to say anything, and nervousness had been permeating everyone's hearts.

"Be careful, there's a cliff ahead!" Yi Yunfei said suddenly, with some confusion in his tone. The few people who walked in front looked back at Yi Yunfei in surprise, and they didn't believe it in their hearts, these people in the front were all the most outstanding disciples of the Famous Sword Sect, and they were walking in the front, also because they had amazing thoughts, and none of them reacted to the abnormality in front, but Yi Yunfei reminded them, and several people felt a little disdainful.

"What is this Yi Yunfei going to do in a daze? Could it be that his eyes can still see secretly? Our divine thoughts have already released a distance of more than a zhang, and they are still at the front of the team, and they have not found anything, but he said that there is a cliff ahead!" A disciple of the Famous Sword Sect muttered in a voice that only he could hear, and continued to walk towards the front without paying attention.

Everyone only stayed for a moment, although they didn't say it explicitly, but their actions had proved that they didn't listen to Yi Yunfei's words. Except for the people from the Wanfu Sect and the Yiyun Sect, the disciples of the other sects hesitated for a moment and continued to push forward.

The poignant voice was louder, as if it was whistling and roaring in his ears, without Yi Yunfei's reminder, everyone also knew to be cautious, so although these people did not stop completely, their pace still slowed down a lot.

After walking a distance of nearly seven or eight meters, the cliff did not appear, and the disciple who was walking in the front with a muttering look back at Yi Yunfei, his eyes were full of mockery. At the same time, he also saw the surprised looks on the faces of the people behind him, and then, the whole world began to spin, and then he saw a headless body appear in front of his eyes, the body was upside down, and the dark red cave wall was still under his feet.

"Isn't this my body, what kind of illusion is this?" the disciple thought to himself, and then he heard countless exclamations, and then the figures of everyone quickly retreated, and then he stopped all his thoughts, and everything in front of him turned into darkness.

The disciple of the Famous Sword Sect died, and no one could see where the attack came from, but it felt as if a breeze was blowing, and there was an extra line of blood on the disciple's neck, and then the disciple's head spun and fell, and the blood shrouded everyone's hearts like a red mist under the light of the torch.

The disciple didn't know that he was dead until he died, there was no pain, no sound, no scream, he fell to the head on the ground, and his face still had a mocking smile on his face when he turned his head to this Yi Yunfei, and his eyes were more blank.
