At the bottom of the tail end of the rift in the center of the Ghost Secret Realm, Ning Xin was rapidly cultivating the Divine Soul Decision, and her location was a hundred meters away from the black hole on the stone wall at the end.

After more than a month of training, she was already very accustomed to the fierce yin qi here, and she didn't need to use the power of the knife into the ground to stabilize her body.

After completing the prescribed cultivation, Ning Xin opened her eyes and looked at the black hole not far away, and then indifferently moved away from the black hole. For more than a month, she would spare a certain amount of time every day to cultivate at a hundred meters of the black hole.

The yin qi in this position is the most violent, but it is not very dangerous for Ning Xin, who is protected by the soul power cover, but because of her cultivation here, her resistance to yin qi is significantly enhanced;

As for the range within 100 meters before the black hole, Ning Xin didn't dare to set foot easily, this area was arranged with a high-level formation, which was very powerful. Although this period of exploration and research has made her more familiar with this formation, she has not thought of any good way to crack it.

According to Ning Xin's analysis, the formation arranged in front of the black hole should be a high-level composite array that integrates the Yin Gathering Array, the Killing Array, the Wind Array, and the Erosion Array.

After countless calculations, Ning Xin found that she couldn't crack this formation in the traditional way.

During this period of time, in addition to cultivating, Ning Xin also reached a place where Yin Qi was not violent to refine the formation, which was the method she thought of for a long time, to break the formation with the formation!

From the few high-level monks she had killed before, Ning Xin had obtained several storage rings, from which she had found a lot of thorn mulberry wood and high-grade ghost beast skins, and now she was rapidly refining the Blank Soul Banner.

She wanted to try to refine a composite array of the Soul Killing Array and the Soul Gathering Array to deal with the high-level compound array in front of the black hole!

The most powerful thing in that formation was the black blades that quickly appeared in the formation, and Ning Xin thought that if something contained those blades, would it be possible for her to pass through that formation and enter the black hole!

Breaking the formation with a formation, Ning Xin had only seen it in an ancient book, and she had never encountered it in reality, so she didn't have a bottom in her heart, but she really couldn't think of any other way to crack the formation before the black hole, so she could only try it with all her might!

According to the principle of the Killing Array, after dozens of failures, Ning Xin finally succeeded in making a Soul Killing Array after spending hundreds of blank soul flags.

After refining the Soul Killing Array, Ning Xin couldn't wait to see its power, and once again came to a position a hundred meters in front of the black hole, and after releasing the divine sense, she quickly arranged the thirty-six soul flags with her soul power, and after a few spells were decided, the Soul Gathering Array and the Soul Killing Array were running in an instant.

Suddenly, I saw countless white lights and black lights flashing in the formation at the same time, and the soul power blade emitting white light was particularly eye-catching in front of the black hole, at first the power of the white blade and the black blade was not much different, but after dozens of breaths, the soul power blade was gradually eroded by the yin qi, and the power began to weaken.

Ten minutes later, the thirty-six array flags arranged by Ning Xin were destroyed, although the formation she arranged did not resist the high-level compound formation in front of the black hole, it still made Ning Xin see hope!

Although the power of the first refined soul killing array was far less powerful than she imagined!

When the soul power blade and the black blade duel, Ning Xin found that the attacks in some places in the formation were very weak, if she could refine a more powerful soul killing array and have more time to compete with the advanced compound array before the black hole, then her chances of entering the black hole would be much greater!

For more than half a month, Ning Xin had been studying how to increase the power of the Soul Killing Array, and dozens of miles away from the end of the rift, more than a dozen high-level cultivators were quickly rushing in the direction where she was!

"Finally got rid of that group of difficult ghosts and wandering spirits!" Zhou Zhixian said stupidly, looking at the only surviving Zhou family monk behind him, his heart was a little depressed, this trip to the rift valley The Zhou family can be regarded as a heavy loss.

There were a total of seven Zhou family monks who participated in this operation, all of whom were distracted cultivators, and now only the two of them were left in the merger period.

"Zhixian, don't be too sad, this time to explore the soul vein, even the four great Yin Emperors have also fallen many high-level cultivators. Seeing Zhou Zhixian's frowning and bitter face, Zhou Zhihua, another elder of the Zhou family, comforted.

"I know, but I'm still a little uncomfortable. Zhou Zhixian said lightly, looked at the Song family monk who was hurrying four in front of him, and sighed in his heart, he was still inferior to Song Qingzi!

"Elder, why do I think there seem to be a lot fewer ghosts here?" Not far away, a distraction monk of the Song family said with some confusion.

"Maybe it's because the yin qi here is gradually decreasing, but you must not relax because of this!" Song Qingzi instructed solemnly, and then swept his gaze to the four people flying in front of him from time to time.

He and Zhou Zhixian took the monks of the Song family and the Zhou family to break out of the encirclement of the group of ghosts and wandering spirits in the center of the rift valley after several twists and turns, and then they kept rushing towards the place where there were few ghosts. A few days ago, they had rescued these four monks from five powerful ghosts.

Later, they learned that these four people were the first group of monks to enter the rift, and at that time they had entered a total of more than twenty people, and now it seemed that only the four of them were still alive!

Among the four of them, there are two Merge Period monks and two Distraction Period monks, one of whom he and Zhou Zhixian both know and is Sun Chuanze, the personal guard of the city lord of Blackwater City!

"Shall we just follow the four of them like this?" Zhou Zhixian flew to Song Qingzi's side and asked.

"Otherwise, they have been at the bottom of this valley for more than two months, so they don't know much about the situation here than we do! Don't you find that the routes they walk are all places with fewer ghosts?" Song Qingzi said lightly.

"The number of ghost wandering spirits is less, but the strength is several times stronger!" Zhou Zhixian said angrily, if he hadn't encountered these powerful ghost wandering spirits, the monks of the Zhou family might not have fallen.

"If we go back, do you think the situation will be better than now?" Song Qingzi asked rhetorically and made Zhou Zhixian shut up!

In fact, for the four people in front of him, Song Qingzi also had reservations, and he made up his mind to follow them, which he decided not long ago, because when he was cultivating, he found that since following them, the soul power in the air seemed to be more refined!

The four people who opened the way in front of them ignored the thoughts of the Song family and the Zhou family monks who were following them, for them, they took these two monks, on the one hand, because they had saved them before;

On the one hand, the further they go to the end of the rift, the stronger and more dangerous the ghosts they encounter, and they need some help, otherwise they may fall into this rift at any time like the monks who came in with them before!

"If we knew we were going to the end of the rift, we shouldn't have entered the rift in the middle of the rift!" Qiao Yong said with great regret.

"Who knew it would be like this! Obviously, the soul power in the center of the rift fluctuated the most, but I didn't expect it to be emitted by countless ghosts. Qiao Meng also said a little depressed, the rift valley where the five brothers entered together, did not expect that now there were only three of them left!

"Don't regret it, be careful with everything around you. We three brothers must get out alive. Having lost his two brothers, Qiao Chen felt uncomfortable.

At the same time, Ning Xin, who was standing a hundred meters in front of the black hole, finally decided to break through the advanced compound array in front of the black hole after several experiments.

Taking out the soul flags that emitted silver light, Ning Xin quickly transported her soul power, using the five-line decisive array technique, and within a few breaths, she arranged the soul gathering array and the soul killing array.

When the two formations began to run, Ning Xin immediately transported the soul power shield and flew towards the weak place in the formation.

At the bottom of the end of the rift, countless white blades flashed continuously, like twinkling starlight at the dim valley bottom, and after more than an hour, the white light gradually weakened until it disappeared!
