Ninefold formation, nine is an approximate number. The nine-fold formation here does not mean that this formation is composed of nine basic formations. Instead, many formations are combined with each other to form a heavy formation, a total of nine formations. Then each of the formations is combined with each other, and they are interlocking. If you want to crack this formation, you must crack each formation at the same time. This is not an ordinary formation, as long as you find the weak link, you can break the formation. This nine-fold formation is more esoteric than the other, and it is more troublesome to crack.

Zhu Yuan has been contemplating for nearly a month, and he can only crack the previous eightfold formation. The difficulty of this last formation is even greater than the difficulty of the previous eightfold formation combined. Moreover, the more you get to the later stage, it is difficult to take a step forward. Therefore, it is reasonable for Zhu Yuan to be trapped in the ninth formation. Only those peerless demons could have cracked the formation in such a short period of time. This is also the reason why the Autumn Immortal has not accepted apprentices, because the Autumn Immortal himself is a peerless demon with extremely high talent in the formation, so he has always wanted to accept a peerless demon as his disciple. The Autumn Immortal took great pains to arrange this ladder in order to find a real peerless demon to be his disciple.

Because he couldn't crack the ninth formation, Zhu Yuan simply didn't rush to crack it. Zhu Yuan sat cross-legged on the eightieth step and began to carefully recall everything that had happened in the more than two years since he arrived in this Autumn Styx Mountain. Of course, the main thing is to recall the formation. There wasn't so much time for him to break the formation from scratch from the first order now. Moreover, it is enough to use this method once, and it will not have much effect if you use it a second time.

What Zhu Yuan has to do now is to keep recalling the formations he had experienced before, as well as his understanding of the formations. Constantly integrate all the formation knowledge. Before, Zhu Yuan's knowledge of the formation was only scattered and separated. It did not become a system, a complete system of formations. In this case, if you are facing those simple formations, you may be able to solve them by chance. However, as soon as you encounter a profound formation, the prototype will immediately appear. Of course, it's also possible to step on dog shit and accidentally crack it. The odds are one in 10,000. Basically, I can't find my way of thinking, I can't figure it out, it's like a dog biting a hedgehog, and I can't get the feeling of being able to swallow it. This is the case with Zhu Yuan now. Although it seems that Zhu Yuan's knowledge of formations is very extensive, Zhu Yuan's knowledge is very complicated, and he can only use this knowledge to solve this kind of formation, and use that knowledge to solve that kind of formation. I can't integrate and use all my knowledge proficiently.

Zhu Yuan also realized this. Now, Zhu Yuan is sorting out all his formation knowledge. Something that makes them come together as a whole, a system.

After the previous half a month of sorting, Zhu Yuan's formation knowledge finally became a unified system of knowledge. If Zhu Yuan's formation knowledge was a point before, then it is a plane now. In the past, Zhu Yuan's knowledge of formations was just a knowledge point. After half a month of hard work, Zhu Yuan combined these knowledge points with each other to form a line, and each knowledge point was connected to each other, and finally connected into a knowledge network. Become an organic whole. Now, Zhu Yuan had mastered all the knowledge of the formation. Even in the process of integration, there are breakthroughs and further progress.

"Alright, let's try to break the formation. If it doesn't work this time, it really can't be done in three years. Zhu Yuan muttered to himself, after all, Zhu Yuan had now reached a bottleneck in the formation. It will not be possible to break through in a short period of time. If you really can't crack the ninth formation this time, then you really can't wait for the ladder in three years. Now there is only less than a year to go, and I don't know how to pass this eightieth order, let alone the eighty-first order after that. This is the last order and the most difficult one.

Zhu Yuan took a deep breath, sorted out his mood, and prepared to crack the formation. After all, this is an extremely critical first order, if you really can't crack it, and you are stuck in the penultimate order, then it is called injustice. There is only one step away from success, but there is no way to take a step. This is the most unacceptable.

Fortunately, this formation did not kill it all, and it also left Zhu Yuan a little respite, so that he could stop and think for himself without being disturbed. If the formation had been attacking, Zhu Yuan would have been killed by the formation long ago. Where is there still a chance to reorganize your own formation knowledge.

Zhu Yuan worked hard and cracked the eightfold formation in front of him one after another.

"Break!" With Zhu Yuan's order, the ninth formation broke in response.

"Hahaha...... I've finally broken it!I'm here after the last order!" Zhu Yuan shouted excitedly with joy beyond words. He was so excited, after a month of hard work, he finally broke through this nine-fold formation. With the speed at which he broke the formation, even he admired himself. This is definitely a peerless demon level.

After cracking the eightieth order of the ninefold formation. Immediately, Zhu Yuan stepped towards the last step, the eighty-first step.

Now that Zhu Yuan can deal with it calmly, no matter what kind of test the last order will face, Zhu Yuan can accept it calmly. This is also the effect that has been honed over the past two years, and now Zhu Yuan is more like a man. Self-confidence, self-improvement, steadfastness, steady...... And many more.

When Zhu Yuan stepped into the eighty-first order, there was only a misty space here, and there was nothing else. Not even a single formation. With Zhu Yuan's current formation attainments, if it is a phantom array, a maze or something like this, it will definitely be discovered by Zhu Yuan. Now, Zhu Yuan can be sure that there is really not a single formation here. If there is a formation test, no matter what the formation is, Zhu Yuan can accept it. No matter what kind of test, Zhu Yuan's state can handle it calmly. But this time, there was no formation, which made Zhu Yuan a little confused.

"What is the test of this level?" Zhu Yuan said to himself.

"The test of this level is me!" suddenly came a voice. It was the voice of the white-robed Taoist in the square.

Zhu Yuan turned around to see that the white-robed Taoist was already standing behind Zhu Yuan. At this time, he was looking at Zhu Yuan with a smile.

"Congratulations, you have successfully reached the eighty-first order. I really didn't misread you, you are the second immortal cultivator to reach the eighty-first order since the creation of this heavenly ladder. I hope you don't disappoint me!" the white-robed Taoist continued.

"The juniors will not let the seniors down!" Zhu Yuan said solemnly.

"I also asked my seniors to give me the questions of the test. Zhu Yuan continued.

"Well, I'm just trying to see if you can pass the test. The white-robed Taoist also couldn't wait to see if Zhu Yuan could pass the test, in fact, deep down, the white-robed Taoist hoped that Zhu Yuan would pass the test. Because he has been lonely for too long, he wants to get out of the body to breathe. Moreover, for some reason, from the first time I saw Zhu Yuan, the white-robed Taoist liked Zhu Yuan from the bottom of his bones. I want to be close to Zhu Yuan.

"Please teach your seniors!" Zhu Yuan saluted respectfully.

"In fact, the test of this level is difficult to say, and it is easy to say. As long as you do your best to arrange a formation, if you can trap me for half an hour, you will be considered to have passed the test. The white-robed Taoist said.

"The younger generation knows. However, there is still something unclear about the younger generation. Zhu Yuan said.

"You say. The white-robed Taoist nodded in agreement.

"If the seniors use immortal means to crack the formation arranged by the juniors, I'm afraid it will be very easy. The formation arranged by the juniors, even if it is mysterious, can only trap the Jindan stage monks. If the seniors break the law with force, and forcibly crush the formation arranged by the juniors with the mana of the immortals, it is not impossible to crack the magic circle. After all, the difference in strength between us is too great. I don't know if there are any restrictions on the seniors to crack the formation, the juniors don't know, and the seniors are asked to make it clear. Zhu Yuan explained.

"I've thought about this for a long time. After you finish arranging the formation, I will use the same level of mana as you to break the formation. You can rest assured that there will never be a force break. The white-robed Taoist explained.

"Thank you seniors, juniors understand. Zhu Yuan thanked him.

"Alright, let's get started! Remember, you have less than a year to go. Come on, I'm optimistic about you. The white-robed Taoist continued.

"Here's what you need. "The white-robed Daoist threw Zhu Yuan a storage ring, which contained a lot of materials for arranging the formation.

Zhu Yuanzhi said that time was pressing, and he had to hurry up and set up the formation. Moreover, this is not like breaking the formation, whether you can crack it or not, you know in your heart. The formation is a test of one's own formation level, and it is difficult to say whether the opponent can break the formation. Of course, the stronger the formation, the greater the chance of passing the test. Moreover, this is not to trap the white-robed Daoist, but only to temporarily trap the white-robed Daoist for half an hour. As long as you can trap the white-robed Daoist for half an hour, you can be considered to have passed the test.

Zhu Yuan took the formation materials and immediately began to set up the formation. In order to make the formation more complex and difficult to crack, Zhu Yuan arranged almost all the formations he knew. After spending several days of exercises, Zhu Yuan finally completed it.

"Senior, junior formation arrangement is complete. Please also advise. Zhu Yuan saluted respectfully to the white-robed Taoist next to him.

"Oh, so fast! Okay, I'll give it a try. The white-robed Daoist did not delay, and immediately entered the formation.

"It's time to go. The white-robed Taoist commanded.

"Yes!!" With Zhu Yuan's order, the formation was instantly urged by Zhu Yuan.

"Boom ......"

"Boom ......"

"Boom ......"

......

There were several loud noises in succession, and in a moment's effort, the white-robed Daoist had already walked out of the formation arranged by Zhu Yuan.
