Jiang Fei nodded and said, "You have to hurry up. Now Zaizai is in danger and we don't have much time."

"Don't worry, I will do my best." Zi Ling said.

Then Zi Ling began to repair the formation with all her strength. Time passed quickly. When Zi Ling portrayed the last rune, her face turned pale with fatigue.

Looking at the repaired formation, Jiang Fei asked quickly: "No problem, is this formation?"

Zi Ling hesitated and said, "This formation is very profound and I am not sure."

Hearing this, Jiang Fei showed a solemn look. Now this magic circle was the only way for them to find Zaizai, and he didn't want anything to go wrong.

Jiang Fei quickly looked at Xuan Yin and asked, "In your opinion, can this formation be useful?"

Xuan Yin observed the formation and said, "This formation is made up of purple spirit, so it is naturally useful, but..."

"Just what?" Jiang Fei showed a look of worry.

"Don't worry, I have already said that this formation is useful, but we may only use it once." Xuan Yin said.

Jiang Fei breathed a sigh of relief and thought that he could use it fortunately. Although there was only one chance, it was enough.

"Then open the formation quickly." Jiang Fei urged quickly.

"Don't worry, I have to take action to use this formation." As he said that, Xuan Yin flew into the formation and began to carve some strange runes in the formation.

Jiang Fei asked curiously: "What is this for? I remember that there seemed to be no runes in the previous formation, so would it have any impact."

"Why, don't trust me?" Xuan Yin said.

Jiang Fei waved his hand and said, "I'm just a little strange, but I don't trust you."

"You're ready, I'll activate the formation now." Xuan Yin said as he quickly made a spell, and the formation immediately started.

The runes on the entire square lit up, and the light of the runes scattered into the air, then gathered together, and then a powerful force of space appeared.

I saw a dark passage suddenly appeared where the rune light gathered. Jiang Fei was very happy to see the passage. The passage was exactly the same as the one described by Black Tiger.

Jiang Fei did not hesitate at all. He led Zi Ling and the others to quickly flash into the passage. A space force came, and Jiang Fei and the others came to a strange place.

This is a place surrounded by mist, and at first glance there are endless clouds. Jiang Fei and the others are standing among the clouds, with a towering mountain in front of them.

Jiang Fei looked at the mountain and could not see the end at first sight. There was a huge hole in front of the mountain, and above the hole, there were several large words with fluorescent colors.

Jiang Fei looked shocked at the big words, because they turned out to be the words of the immortal world, meaning the cave of the ten thousand spirits.

Jiang Fei quickly closed his eyes and wanted to sense the situation in the Ten Thousand Spirit Immortal Cave, but to the surprise, he could not sense anything at all. The Ten Thousand Spirit Immortal Cave had a powerful force to block his investigation.

"It's not a pity that it's the Ten Thousand Spirits Immortal Cave. With my current strength, I can't detect the situation inside." Jiang Fei said in shock.

You should know that Jiang Fei now has completely controlled the Tianxuan Stone, but he is unable to detect the situation in the Immortal Cave of Ten Thousand Spirits.

Since he could not detect and Jiang Fei was too lazy to waste time, he flashed towards the Wanling Immortal Cave and came to the entrance of the Wanling Immortal Cave. He was shocked because Jiang Fei actually sensed the fairy energy here.

"There is actually a fairy here." Jiang Fei said in shock.

"This place is called Wanling Immortal Cave. Since it has the word "Immortal" and it is not surprising that it has the aura of immortality." Xuan Yin said with a smile.

Jiang Fei frowned and said, "I didn't expect that there was a powerful restriction power at this entrance."

According to Jiang Fei's investigation, he found that there was a powerful ban at the entrance of the Wanling Immortal Cave. He wanted to forcefully break the ban, but this place was the Wanling Immortal Cave. He was worried that forcibly breaking the ban would cause a change.

"Don't worry, this is just a ban to resist the leakage of fairy energy in the immortal cave of the Ten Thousand Spirits. It has no effect. Let's go in." Xuan Yin said.

Jiang Fei breathed a sigh of relief, and he quickly flashed into the Ten Thousand Spirit Immortal Cave. As soon as he stepped into the Ten Thousand Spirit Immortal Cave, Jiang Fei suddenly felt a powerful space power surge, and then he appeared in a place that was both familiar and unfamiliar.

Looking at the scene in front of him, Jiang Fei stood there in a daze, because everything in front of him was too familiar, everything here was exactly the same as the Wanling Mountains. If it weren't for the fairy spirit, Jiang Fei would have mistakenly thought that he had not left Wanling Mountains, but was still staying there.

"How could this happen? Why is it exactly the same as Wanling Mountains?" Jiang Fei said in confusion.

"How do I know this?" Xuan Yin spread his hands and said.

Seeing that Xuan Yin had no idea, Jiang Fei was too lazy to think about it. He quickly sensed it, trying to find Zaizai and the others, but to his surprise, his sensing was affected here and he could only sense a very short distance.

Jiang Fei frowned, and he said with a worried look: "I didn't expect that I had completely controlled the Tianxuan Stone, but I was still restricted here."

At this time, Jiang Fei was very anxious. Although he had come to the cave of Ten Thousand Spirits, his senses were restricted and he could not find Zaizai at all.

Xuan Yin observed the surrounding situation and said, "Don't worry, although this place restricts your senses, I think this place should be the same as the Wanling Mountains. As long as you think about the Wanling Mountains, you will naturally understand the situation here."

Hearing Xuan Yin say this, Jiang Fei quickly recalled the overall situation of the Wanling Mountains. He said in shock: "I just realized now that the Wanling Mountains seem to be a natural formation."

"Oh, do you have something to see?" Xuan Yin asked hurriedly.

"I recalled the appearance of the Wanling Immortal Cave. Every mountain peak here seems like a rune, and the entire Wanling Mountains are composed of those mountain runes." Jiang Fei said.

"Then can you tell what formation it is?" Xuan Yin asked hurriedly.

Jiang Fei shook his head and said, "I can't see what formation it is, but I can print it."

As he said that, Jiang Fei's magic tricks were repeatedly played. He printed out the overall situation of the Wanling Mountains, and then let Xuan Yin and Zi Ling observe.

Seeing the picture printed by Jiang Fei, Xuan Yin showed a look of shock. He said incrediblely: "The Heavenly Xuan Formation."

"The Heavenly Profound Formation? Why have you never heard of it?" Jiang Fei asked in confusion.

"The Heavenly Xuan Formation is a powerful formation created by the Heavenly Xuan Immortal Emperor back then. This formation is very special. It is a trapping array and a guardian array. However, whether it is a trapping array or a guardian array, it must have fairy energy to operate." Xuan Yin said.

After hearing this, Jiang Fei finally knew why this place is the same as the Wanling Mountains. Although the Wanling Mountains are formations, they cannot operate at all. It is different if there is fairy energy here.

"Since you know this formation, you should know where Zaizai will be trapped." Jiang Fei said quickly.

At this time, what Jiang Fei was most worried about was Zaizai. He thought that since Xuan Yin knew that the Ten Thousand Spirit Immortal Cave was a huge formation, he should have some understanding of this formation, and perhaps know where Zaizai would be trapped.

Xuan Yin thought for a while and said, "Since this is the Heavenly Xuan Formation, I think I know where they are. Come with me."

As he said that, Xuan Yin flew in one direction. Jiang Fei did not hesitate at all, and he hurriedly followed.

Jiang Fei and the others walked for a while, suddenly they heard a huge roar. Jiang Fei was shocked, and he could hear that it was Zaizai's roar.

Jiang Fei quickly accelerated his pace, and soon a shocking scene appeared in front of his eyes. Jiang Fei from afar saw the huge body of the Demon Nightmare beast floating in the air, and a huge magic circle shining on the head of the Demon Nightmare beast.

At the same time, there were eight powerful immortals sitting around the nightmare beast. They were pinching the marks in their hands and constantly making magic tricks.

Jiang Fei quickly flashed and wanted to rush forward to help the nightmare beast, but Xuan Yin grabbed it.

"What are you doing? Why don't you let me help Zaizai?" Jiang Fei glared at Xuan Yin.

"What are you anxious about? Not only can you not help it when you go up now, but you will also harm it." Xuan Yin said hurriedly.

Jiang Fei was shocked, and he said anxiously: "What should I do?"

Xuan Yin pointed to the nightmare beast and eight immortals in the air and said, "I told you before that this immortal cave of all spirits is the Tianxuan Formation set up by the Tianxuan Immortal Emperor, and their current location is the core of the formation."

Xuan Yin paused and continued: "The Heavenly Profound Formation is both a guardian formation and a trapping formation. I think the Demon Nightmare Beast should want to use the Heavenly Profound Formation to trap those immortals, but it did not expect that the Immortals actually understood this formation and were trapped in it. At this time, their power is in a state of balance. Once you join rashly, the balance may be broken, and then it may harm the Demon Nightmare Beast."

Jiang Fei was still scared when he heard these words. He didn't expect this situation to happen. Fortunately, Xuan Yin grabbed him, otherwise he wouldn't know what would happen.

"What should I do now?" Jiang Fei asked quickly. He had no idea about this formation at all, so he could only turn to Xuan Yin for help.

"Wait!" Xuan Yin only said one word.

Jiang Fei was stunned. He didn't expect that Xuan Yin only said the word "wait". He said anxiously: "What is this?"

"Now the power of protection and the power of siege are in balance. As long as you intervene, you will definitely break the balance. No one will predict what will happen at that time, so we can only wait." Xuan Yin said.

Jiang Fei was very anxious. He looked at Zaizai in the air and said, "How can you let me wait with peace of mind?"
