Jiuyuan said it solemnly because he wasn't sure.

But this sentence suddenly shocked Mu Feng's body. If he had seen it before, he would definitely know the way to solve it. When Wudian Jinshu followed his previous master to travel around the country, this insight was really not concealed.

But even Jiuyuan himself was not sure. He could only let Mu Feng go to a few specific places to observe the formation.

"Look, is there a vortex above this barrier?"

After arriving at a place, Jiuyuan asked Mu Feng to stop.

Mu Feng looked over carefully, almost put his face on the barrier, and finally saw the vortex that Jiuyuan mentioned.

The surface of the barrier was originally as calm as flowing water. If Jiuyuan hadn't reminded him that he had looked so carefully, he wouldn't have seen that there was a small vortex here.

This vortex is very inconspicuous, even if he almost didn't see it himself. But after seeing it, he was immediately delighted.

A smile appeared on Jiuyuan's face at this moment, and he slowly said, "Go to the next place!"

Soon, they came to another place and observed again and found that there was also a subtle vortex here.

They circled around the formation and found nine vortexes. Jiuyuan said it very accurately every time, so he became more and more confident.

"Yes, I have indeed seen this formation before. Those vortexes are the formation eyes of the formation, but they are much less than what I have seen. They should be a simplified version."

"Now, do what I said!" Jiuyuan said excitedly, "The flaws of this formation will move at any time. If you can find the flaws, you can break the formation."

Mu Feng was also very excited, but it was getting late at this time, and there was not much time left for them.

At this time, Huo Shenji and others no longer had hope for him, and they could only wait quietly outside for the final result.

However, at this time Mu Feng came to the main entrance of the palace and gently placed it on the barrier, causing slight ripples.

"What is he doing?" Luo Yuanping frowned and asked in confusion.

The others shook their heads, not understanding the significance of Mu Feng's move. Even Liu Rufeng looked over carefully at this moment.

"Boy, remember that the formation is like a living creature, and it also has 'breath'. This 'breath' is the energy flow in the formation. As long as you can grasp the flow route, any formation can be broken!"

Jiuyuan's voice sounded in Mu Feng's ears, and then it directly merged into Mu Feng's consciousness and controlled Mu Feng's body.

In the lower realm, when Mu Feng encountered a fatal crisis, he did this, which could instantly bring great combat power to Mu Feng.

But after he came to the upper realm, he never passed by. After all, even if he controls Mu Feng's body, he cannot bring much improvement to Mu Feng.

Now, he needs to personally sense the energy flow trajectory in the formation and find out the flaws of the formation. And Mu Feng's senses are naturally still there.

At this moment, he was trapped in a mysterious feeling. The huge formation in front of him seemed to have turned into a flowing stream, and he was conscious of the trajectory of the flow of the stream.

But the trajectory is very messy, as if hidden in layers of illusions.

I don’t know how long it took, but his consciousness suddenly shook, because at this moment he could clearly feel that in the barrier in front of him, countless energy was slowly flowing.

Just like a human body, there are countless meridians. This must be because of Jiuyuan, but he remembered this feeling deeply in his mind.

When he practices the Tianyan Divine Machine in the future, he will be able to gain a great opportunity!

Jiuyuan controlled Mu Feng's body at this moment, so there was naturally danger of being exposed, but Huo Shenji and others did not respond. They probably did not notice it, which made the two of them breathe a sigh of relief at the same time.

After understanding the trajectory of the energy flow in the formation, the flaw was about to emerge. Jiuyuan found out the flaw in a very short time!

Then, he retreated back into the wordless golden book, and no energy fluctuations were generated during the process, and no clues were discovered.

Mu Feng regained control of his body, and he naturally knew the flaw. At this moment, the coffin nail suddenly flew out on his body, covering it with amazing power of the soul!

"Wow, this kid's soul is strong enough." Lin Pingzhi couldn't help but speak out.

However, at this time their attention was more on the coffin-suppressing nails. Mu Feng made moves, could he really break the formation?

Their breathing was lighter, fearing that they would disturb Mu Feng.

The flaws in the formation are constantly swimming, so they can only lock in a moment, which is why Mu Feng uses the coffin nail.

The coffin-suppressing nails driven by the power of the soul are faster than all his methods!

The next moment, a firm light flashed in his eyes suddenly. With a thought, the coffin-suppressing nail suddenly turned into a black light, pricking heavily on a place in the barrier.

That place is directly above the palace gate!

Suddenly, the barrier of the entire formation shaking violently at this moment, as if a large stone was suddenly thrown into the calm lake, causing violent ripples.

"Dear Palace Masters, join forces to attack this formation now!" He suddenly roared.

Huo Shenji reacted first at this moment, and at this moment the powerful force poured out without reservation and bombarded the barrier.

The other hall masters also woke up from the shock. Was this formation that even Liu Rufeng could not break was shaken like this?

Although they were shocked and puzzled, they did not stop and attacked the shaky barrier.

Only Liu Rufeng was standing there blankly, as if shocked.

Bang!

With a crisp sound, the entire barrier suddenly disappeared, the formation stopped operating, and the situation in the palace appeared in front of them very clearly!

"Great, broken!"

Luo Yuanping seemed very excited and ran directly to Mu Feng's side and patted Mu Feng's shoulder heavily: "Good boy, you really have you, it's really hidden!"

"I hope it's time." Mu Feng couldn't laugh. After all, it was almost dark now, and I wonder if the prince had succeeded.
Chapter completed!
