The moment the thunder sounded, Ning Xin also felt it, but she thought that the well was connected to the river outside, and it was not strange to hear some thunder, so she didn't pay much attention to it after that, and concentrated on studying a few words on the well.

After a while, Ning Xin suddenly thought of something, and immediately entered the space, checked her whole body, and found nothing unusual, before she breathed a sigh of relief. She hadn't forgotten that when she first entered the canyon and heard the thunder, she didn't think anything was wrong at the time, but then she almost became deaf.

"I didn't take the Ethereal Pill, why is the thunder in here useless to me?" Ning Xin had some doubts in her heart.

"Could it be because of that silver transparent bubble?" Xiaobai said.

"Could it be? That bubble can block out the sound in addition to protecting the spirits? But it's also possible that the bubble was formed in the thunder, rain and fog, and should be able to prevent the thunder from interfering. ”

Knowing that she would not be affected by the thunder, Ning Xin came out of the space again, and in order to be safe, she also ate an ethereal elixir, and then focused on observing the changes in the bubbles in the well, those bubbles continued to break and emerge, and then combined with each other to form larger bubbles.

After a period of time, Ning Xin observed that the big characters on the well mainly changed their positions according to some of the slightly larger bubbles, and as long as the larger bubbles reappeared in the well, the positions of those big characters would definitely change once.

What does the change in position of these words imply? Just as Ning Xin lowered her head and pondered, suddenly a white light flashed on the words, so fast that people wanted to see it clearly, it had already disappeared.

Although Ning Xin didn't see the white light clearly, she could clearly see the white stripes reflected on the ground at the bottom of the abyss when the white light flashed, and when she saw the white stripes, Ning Xin thought of the formation in her mind, and at the same time breathed a sigh of relief in her heart.

It's good to have a formation here, as long as she can break the formation, she can leave here, although she knows that this formation may be extraordinary, but Ning Xin's mood at this time is still much more stable than when she got nothing before.

For Ning Xin, the unknown waiting is the most dangerous, because she doesn't know how to start, knowing that there is a formation at the bottom of this abyss, although it may be difficult to crack, it still gives her peace of mind, because she knows which direction to use.

After a period of observation, Ning Xin found that the words on the wall of the well would only appear in a hurry once if there were bubbles with a diameter of more than one meter in the well, and at this time, it had been a year since the first white light flashed.

Looking at the three pinstripes on the ground that were far apart and without any regularity, Ning Xin felt a little emotional, she didn't know what year and month it would take for her to find out the pattern!

At this time, Ning Xin was not the only one trapped in the Empty Ming Cave Heaven, there were also those demon cultivators who had broken through the Thundering Domain, but their situation was much worse than Ning Xin's, and most of them were injured.

"Elder Murong, what should we do now?" a demon cultivator asked with a worried expression.

At the beginning, there were nearly a hundred of them in total, and only less than thirty people broke through that giant cave, and the others all fell in the giant cave, and they later knew that place was the Thundering Domain, if it wasn't for the crisis, Elder Murong took out the Ethereal Spirit Pill in time, it is estimated that none of them would survive.

However, in the Thunder Domain, the Ethereal Spirit Pill was no longer as useful as in the Unconscious Canyon, and could only withstand some of the thunder attacks, so although they survived, they were all seriously injured.

I thought that they would be able to reach the entrance of the Ancient Demon Palace marked on the map smoothly after that, but they didn't expect that not long after the Thunder Domain, an even more powerful lore array appeared in front of them.

They have been trying to crack this formation during this time, but they have not succeeded, and a few more people have fallen in the broken formation, and those who fell into the formation were instantly broken into pieces. Now they have been trapped here for more than a year.

Murong Junbo looked at the lore array in front of him expressionlessly, holding the only remaining bottle of Ethereal Spirit Pill in his hand, plus the people of the Ghost Sect, now they only have more than twenty people left, but even if he wants to go back, the Ethereal Spirit Pill in his hand is not enough, he only has ten Ethereal Spirit Pills.

Dugu Cangjue's face was very bad at this time, more than thirty people from the Ghost Sect, only eight of them have survived now, and when they broke through the Thunder Domain, there were still more than ten people left, but they didn't think that a few more died when they broke the lore array.

"What do you ghost sects think?" Murong Junbo asked Dugu Cangjue.

"With our strength, this lore array may not be able to be broken, I don't know what Elder Murong thinks?" Dugu Cangjue calmed down for a moment before he spoke.

"If you don't go forward, then you can only retreat!" Murong Junbo thought for a while before saying, then closed his eyes.

"The Thundering Domain is so powerful, can we break through again?"

"Yes, even if there is an ethereal elixir, we are all so seriously injured, we may not be as lucky as the previous time. ”

Hearing the people of the Demon Palace mention the Ethereal Spirit Pill, Dugu Cangjue's heart sank, and he quickly looked at Murong Junbo with his eyes closed, they couldn't crack the lore array This is an obvious thing, this Murong Junbo definitely knows, but he didn't give the order to let them return for a long time.

Before, he thought that Murong Junbo wanted to continue to search for the Ancient Demon Palace, but now it seems that the Ethereal Spirit Pill in his hand is not enough! If this is the case, the people of their Ghost Sect will definitely be given up by him.

It may be that Dugu Cang's gaze is too strong, Murong Junbo felt it, opened his eyes and glanced at him, but he didn't say anything, and closed his eyes.

"I only have ten Ethereal Pills, I can give you one, and you can do the rest yourself!"

At this time, outside the Wujue Canyon, the disciples of the major sect families found this place according to some traces left by the demon cultivators, but since the leader of the team was a well-informed Yuanying monk, it didn't take long for the disciples of the various sects to know that this was the Thunder Rain Fog Valley, one of the top ten most dangerous places in the Tuyue Continent.

"This is the legendary Wujue Canyon where monks can be killed unconsciously! Do you say that the thunder, rain and fog inside are really that powerful?" Mu Shuilan asked Xia Wang and the others.

"Absolutely, once my grandfather came here, fortunately he was more cautious at the beginning, and returned in time before entering the depths of the canyon, when he came out of the canyon he found that his senses were damaged, and it took nearly ten years of cultivation to recover, and when he was in the canyon, he didn't feel it at all. Murong Xuan said slowly.

"That voice from before should have come from here!" Han Rou said with a stern expression.

"Yes, if you think about how you felt at that time, you will know how terrifying it was inside!" Murong Xuan said.

"What about those demon cultivators, aren't they afraid?" Xia Wang asked.

"Or maybe they had some way to avoid the thunder and fog, or maybe they didn't go in at all!"

"Do you think the Luo family is mistaken, we have been in this Dark Hell Forest for so long and not a single demon cultivator has found out!"

After the monks of the other sect families around knew that this was the Wujue Canyon, they all had a heated discussion as fiercely as Xia Wang and the others.

Several Yuanying Cultivators looked at the canyon in front of them, and their hearts were very heavy, "Peerless True Monarch, what do you think we should do now?" asked Shen Yi True Monarch of the Tianyi Sect.

"I think we should withdraw first, even you and I have to be extremely cautious when entering this Unconscious Canyon, if you are not careful, you may fall, this is not something that the disciples in the sect can deal with. ”

"I think so too, we haven't seen the demon cultivator enter with our own eyes, it's really not good to let the sect disciples get into danger for this uncertainty! What do you fellow Daoists think?"

"Shen Yi Zhenjun is right, let's withdraw first, discuss it carefully, and then decide whether to continue to search those demon cultivators!"
