The combination of runes is all in front of it, but there are not too many ways to form a complete formation, especially after the runes used are limited, then there are even fewer choices.

However, even if this is the case, the option to rearrange and combine is not something that everyone can find, and it is necessary to have a deep understanding of the entire formation and runes to be able to do so.

In the process of constantly searching for the best permutations and combinations, Zuo Feng also seemed to understand the general purpose of Fu Maniac in the first place. It is the most important rule of their Yong family, and they can't let outsiders get their own essence inheritance of these four sets of great arrays.

Only those who have a deep understanding of the entire set of formations can find the Fu Crazy Testament that they have seen. However, if you want to find another testament, you need to understand this formation thoroughly.

That is to say, the person in the family who has really mastered the formation can open it and take out the complete Fu Mania Testament Book, and let the selected descendants practice it, and even if outsiders come to obtain the Willful Book that they have seen, they will only end up going astray.

It turned out that this was the purpose of the original rune maniac, in order to prevent the rune he created from being obtained by outsiders, after leaving this huge formation, he also left a trap. But for some reason, this was originally a method used to deal with outsiders, and in the end he treated his own people by mistake. ’

Zuo Feng had doubts in his heart, but the speed at which he rearranged the runes was getting faster and faster. The way he comprehended was a method of reverse deduction, which belonged to another way to master the four complete sets of large arrays, and would never be affected by the traps left by Fu Maniac.

However, Zuo Feng also knew in his heart that he would be able to succeed in the end, and in fact, the rune books that Ning Xiao kept in Najing played a decisive role. Another important reason is what you saw when you were in the gourd valley by chance, and when you activated the hidden ability of the prison lock.

At that time, absorbing the power of those spaces, the prison lock had a huge change, and he was in that special space, watching the power in the prison lock, helping the teleportation formation to repair the missing parts, in this whole repair process, Zuo Feng personally watched a set of broken formations be reawakened, which was of great help to him in the rune formation.

What's more, in terms of the rune composition of that teleportation formation, Zuo Feng always felt that there was a slight resemblance to the huge foundation formation he saw now, but he couldn't tell where the specific connection was, and even after careful study, it seemed to be his own illusion.

Without these reasons, even if Zuo Feng saw the good of the Magnetic Spirit Stone Formation and the key starting point in it, he would not be able to deduce it retrograde at all and truly master the entire basic formation.

It can be said that there are too many coincidences in this, which makes people feel that Zuo Feng is the lucky one. But those are really lucky, and they may not be at all, at least Zuo Feng doesn't think it's inevitable.

The experience of obtaining Na Jing was that Zuo Feng was attacked by Zuo Lie, the great elder of the village, behind his back, and he almost died when he obtained the inheritance of Ning Xiao.

Activating the potential within the prison lock, Zuo Feng even had the heart of death, if it weren't for the spatial rupture and the appearance of countless spatial blades, he would probably have died in the hands of the people of the Thousand Illusion Sect's Bloodthirsty Hall.

After several brushes with death, he had the ability to see through the reverse deduction of the formation later, and these are probably not accidental luck, but the inevitable result of his death.

The runes in his mind were still constantly regrouping, and whenever a set of formations appeared, Zuo Feng immediately readjusted the rune bricks in the four-story room according to its layout.

Finally, the runes in his mind stopped, and everything gradually calmed down, and in Zuo Feng's calculations and deductions, he had almost tried the spirit gathering formation that these runes could combine. No matter how powerful the formation was, as long as he could complete the Spirit Gathering Formation, he tried it with enthusiasm, but in the end, it didn't cause any changes in the mechanism, and no secret grid appeared.

He had removed almost every rune brick, and he had checked the bottom of each turn, and there was no room for anything.

I believe that before me, there should have been a Yong family who tried to remove these rune bricks, and the result obtained was probably as disappointing as myself.

If it were someone else, I am afraid that at this time I would have already begun to consider giving up, or denying my original guess. But Zuo Feng will not, relying on a completely objective judgment of the whole thing, he always believes that his speculation is not wrong, but there is a problem with his own method, or he has deviated from his thinking.

Sitting cross-legged on the fourth floor of the stone castle, the left wind sometimes looked around, and sometimes closed his eyes in contemplation. At this time, calmness is the most important, even in the face of the important time of life and death, Zuo Feng can still try to make himself as calm as possible to think and judge.

Now he is still able to be calm, not impatient, but to return to the train of thought again. Initially determined that this place had the other part of the Fu Maniac Legacy Book came up, and continued to think about it along this line.

Suddenly, in Zuo Feng's closed eyes, the pupils of his eyes twitched rapidly, and the strange appearance of the real stone castle quickly appeared in his mind.

The stone castle is divided into four layers, and I have a very strange feeling when I first see it, and after careful observation, I understand that this is the result of the four sets of formations fitting each other. After the four sets of formations were combined, the formations were completely solidified and built into the stone castle where it was at the moment.

"Fit, fit with each other, this seems to be the key, I seem to have been thinking about the entire fourth layer of the forbidden formation independently, but ignoring the previous three layers of formations. Since the Fu Maniac has built the entire stone castle into this shape, the key lies in the fit between them. ”

Zuo Feng muttered to himself, and his eyes opened abruptly at this moment, and he didn't deliberately observe and memorize the runes around him, because the runes around him were in his mind.

It's just that this time there are also three other formation runes that appear at the same time, a total of more than 72,000 runes appear in my mind at the same time, this is all the runes of the four formations.

If it were someone else, not to mention thinking about the more than 72,000 runes, even if they were to be in their minds at the same time, they would not be able to do it at all. Doing it reluctantly will only make people fall into madness, or directly become stupid.

At the same time as these 72,000 runes appeared, Zuo Feng suddenly showed a smile, which represented that he believed that he should have taken another step forward and was closer to the final answer.

Being able to generate 72,000 runes in your mind at the same time, and also allowing them to deduce and calculate in your mind, requires the cultivation of the God Refining Stage realm. I'm afraid that such a character will not spend a lot of effort to comprehend the four sets of basic formations here, because for that kind of cultivator, it not only lowers his own value, but also does not have much value and significance.

Zuo Feng is now more sure that his current thinking is correct, and he will not waste time, and his eyes slowly closed again.

The moment he closed his eyes, the runes in his brain began to change rapidly, and the seven thousand two hundred runes were quickly superimposed together, this superposition was not a simple coincidence, but a kind of finding the best fit point in the process of the formation operation, and then letting each other gather together.

Although there were 7,200 runes, only more than 1,800 of those runes were faintly shimmering in Zuo Feng's mind, and these 1,800 runes were all the runes of this Fourth City.

Zuo Feng believes that the key to solving the mystery is in the fourth city, so it will not involve the runes used in the other three layers, but only needs to use the runes of the other three layers to find the final appearance of this formation after the combination.

In this process, Zuo Feng not only needs to involve the other more than 5,400 runes, but also excrete them as much as possible, and finally leave the arrangement of the 1,800 runes.

Half an hour later, Zuo Feng suddenly opened his eyes, and at the same time, his body moved. At the same time, the aura quickly emanated from its body, and according to the control of the left wind, it covered the rune bricks one by one, and then the rune bricks were lifted one by one.

Zuo Feng's eyes were like electricity, and he stretched out his hand to point or pat on the runes that were lifted in the air, and the rune bricks would quickly fly to the designated position according to his instructions. He already knew the location of each of these runes, and he almost didn't need to look at it a second time to make sure, and he smoothly arranged the location of all the rune bricks.

During the whole process, in Zuo Feng's mind, there was always a glittering formation frozen there. At the same time, more than 5,400 other runes were also completely solidified, and this was the final result of the merger.

The stone castle is the result of the condensation of the four formations after they are stacked and combined with each other, and the formations in Zuo Feng's mind now are the result of fusing with each other and almost overlapping.

In fact, he had seen it a long time ago, but it was only now that he finally understood that this maniac had good intentions and took great pains for his descendants.

When all the more than 1,800 runes were arranged according to the position in his mind, a crisp and subtle "click" sound sounded at Zuofeng's feet.

If it weren't for the fact that there was a fat man on the first layer below, he would probably scream excitedly now, which felt even cooler than the original reverse derivation of the Magnetic Spirit Stone Formation.

This is a problem set by the maniac in front of him, and he can solve it, and his sense of accomplishment is self-evident.

Suddenly, out of the corner of his eye, he saw the last step of the stone staircase that came up from the third floor not far away, and it slowly moved, and the stone staircase was slowly erected.

As it slowly erected, Zuo Feng could clearly see that it was empty, and the booklet that had been clumped into a roll was placed in it.

"It's done, with this, it should be a complete Fu Maniac Testament!" Zuo Feng subconsciously said.
