In the past, Tang Zai's cloth was all small formations, just find a position to locate first, and the rest can be arranged according to the principle of the formation, but this time he wants to lay out a super large formation, and everything is not so simple.

The size of the formation itself has nothing to do with the grade, only the effective range.

But having said that, in fact, the larger the formation, the higher the requirements for the ability of the formation. This is like the difference between a bungalow and a skyscraper, when the number rises to a certain level, it will change from quantity to quality, and its complexity is far from being comparable to that of ordinary small arrays.

The positioning of the eight gates alone involves a radius of dozens of miles from Lao Yaling, that is to say, the distance between the eight gates may be several miles long. Such a long distance must have an impact on accuracy, and thus on power, and may not even be able to form a formation.

Tang Zheng came to Lao Yao Ridge this time, not simply for the fire crow spirit as he said, but with a greater purpose, and this purpose even required him to use a large array that enveloped the entire Lao Yao Ridge for dozens of miles.

This kind of large array is the first time for Tang Tribulation.

Because of this, Tang Zheng also had to draw a map first, and then repeatedly simulate it on the map, not only to accurately measure, but also to observe the terrain to see if the terrain was suitable for use.

In addition to the difficulty of positioning, the large-scale formation also has the problem of huge material consumption.

The larger the range, the more material is consumed. With such a large range of formations, even the use of the most ordinary materials could bankrupt Tang Zheng.

Tang Zheng naturally couldn't take out this lot of money, but fortunately, he studied under Xu Muyang, and he paid attention to the way of nature, and the formation path was integrated into nature and borrowed the power of heaven and earth to do it, so there was still a way to take advantage of it. However, in this way, the terrain requirements are high.

For example, if he wants to set up an extremely hot prison array, the door of death needs the main fire. If you want to make the main fire of the Gate of Death, you must not spread it in a place where there are mountain springs, and not only that, but you must also block the water source through the Dumen change. And if you want to keep the door of death away from the water, the best way is to stand under the western slope of the ridge. However, if the door of death is built here, it will be on the slope.

Looking at its position, it is on the incense accumulation hole.

Tang Zheng naturally didn't think that he could spread the formation to the door of the Phantom Demon Fox's house without being noticed, so this Extremely Flame Helling Formation had to give up and try other formations.

It's just that no matter how he changes the formation next, he can't get around the threshold of Xiangji Cave.

It was like a wedge, firmly fixed on the Old Crow Ridge, making it impossible for Tang Zheng to implement all his ideas, so angry that Tang Zheng had to scold: "Damn, it actually occupied the land, no wonder there has been no formation master to clean it up all these years!"

The formation road has extremely high requirements for the terrain, so the terrain is classified and described in great detail.

In Xu Muyang's "True Solution of the Formation Dao" to Tang Zheng, there is a special topographical chapter, which specifically explains the influence of various terrains on the magic array.

The so-called return to the ground, that is, the place of return, is the most central place of all terrain.

Occupying the land means occupying the most important position in the land, and all the circle arrangements cannot bypass this place. On the other hand, the other side can take advantage of this to gain an advantageous position, and it is not impossible to even counterattack.

It is like a turning point in a war, a winner or loser in Go, which is of great significance and far-reaching influence.

This Xiangji Cave is so immortal, it is actually built on the status of Lao Yao Ridge, so that Tang Zheng's plan to deal with the Phantom Demon Fox will suffer a major setback as soon as it comes up.

That's right, the real purpose of Tang Tribulation is naturally not the Crow Fire Spirit, but the Phantom Demon Fox itself.

If this purpose is known to Qin Zhou, Wei Tianchong and others, I am afraid that they will be frightened.

You must know that this phantom demon fox is not another existence, it is a demon that can be transformed in just one step. Its strength is equivalent to the pinnacle of desecration, even if it is Nanbaicheng, Gu Changqing and others can't compare, not to mention that there are a bunch of little demons under the hands of this demon fox, and there are many enlightened beings.

With Tang Zheng's current strength, if he wants to destroy this group of monsters, the difficulty is many times greater than that of the first man in the Demon Slaying Dao.

It was precisely because of this that Tang Zheng put his hope on the formation, which was also the only chance for him to transcend the level and create miracles, but he didn't expect to encounter this kind of thing.

"Is it a coincidence, or is this demon fox also through the formation?It shouldn't be......" At this moment, looking at the terrain on the map, Tang Zheng was also frowning and muttering to himself. A wild fox, there is no reason to understand the way of formation.

Thinking of this, he looked at it carefully, all the terrain in the map came into his eyes, and his mind gradually became clearer, Tang Zheng continued to say to himself: "The land is occupied, the ground is in sight, the potential land still exists, there are no soldiers on the heavy land, and the road is cut off alive...... It should be just a coincidence, otherwise it would not be possible to just occupy the land. ”

There are eleven important places in the topography of the formation, the most important of which is to return to the ground, which is the place where the magic array returns to its source; secondly, it is to sit on the ground, which has the ability to sit and look at the eight wildernesses, and all things are in the heart; again, it is the potential land, and it is expected to take advantage of the momentum and win the battle; again, it has the ability to strengthen the magic and arts; and again, it has the purpose of retreating and escaping......

Now this Xiangji Cave only occupies the land, but the land, the land, the living land, and the heavy land are not occupied, Tang Zheng judged from this, this demon fox is pure luck. The scenery of this Xiangji Cave is very beautiful, and most of the demon foxes chose this place because of this.

It's just that whether it's a coincidence or intention, for Tang Zheng, this is always a big trouble, so Tang Zheng can't help but fall into meditation, looking for a solution, and his eyes are constantly patrolling the map: "The land is occupied, the big array is difficult to achieve, the only way is to narrow the scope and open up another battlefield." But in this case, you have to lure the fox out......"

"Isn't that too risky?" said Iyi.

The small scale is not only dangerous to lure the fox, but the most important thing is that it is difficult to put all the targets in the formation in the process of luring the enemy into the battle. Once the great array is activated, the demon beasts outside will be alert and will never re-enter.

In this way, not to mention the less trapped demon beasts, these demon beasts are more likely to attack the large array from the outside and destroy it.

However, for Tang Zheng, he had no choice.

If you want to create a miracle, you must take great risks, and he did not expect this trip to be smooth sailing.

"It's always adventurous. Tang Zheng said lightly.

Yi Yi was frightened when he heard this, and threw himself into Tang Zheng's arms: "Brother, if it really doesn't work, let's forget it." ”

Tang Zheng has said categorically: "No, if I want to deceive the Heavenly God Palace, I must have an external incarnation, and this demon fox is the only one who can help me do it now." ”

For Tang Zheng, if he wanted to enter the secret land of Tiandu Mountain, the biggest difficulty was not to break the formation, but how to avoid the surveillance of the Heavenly God Palace.

It is impossible for ordinary disguise and transformation techniques to hide from the Heavenly God Palace, and the only way is to incarnate outside the body.

But the incarnation outside the body can only be mastered at the Tianxin level, with Tang Zheng's current strength, he doesn't want to have it in another hundred years, so Tang Zheng can only turn to him to beg, this phantom demon fox is the target he chose.

The Phantom Demon Fox's talent is ever-changing, and after killing it, he will get his demon pill, and with this thing supplemented by soul jade fragments and then refined by secret methods, it is possible to obtain an out-of-body incarnation.

This method Tang Tribulation is still obtained from the Supreme Heart Sutra of the Supreme Heavenly Treasure, the essence of the Five Divine Sect is good at the secret method of the divine soul, and even the puppet can send the soul, and there is no problem in creating an external substitute. Of course, this technique is far worse than the real incarnation outside the body, there is no possibility of cultivation, and the strength will be weakened, and it can only be regarded as a stand-in outside the body, but the possibility of it being pierced is greatly reduced.

According to the Heart Sutra, unless such a stand-in is visited by a Purple Mansion level powerhouse in person, or a person who has comprehended the way of insight has the heart to observe, the ordinary Tianxin level will not be able to see the authenticity.

But it is also not easy to do this, the phantom demon fox is not easy to match, but it is precisely because of this that he has to do it even more.

If a major sect like the Heavenly God Palace wants to use any tricks to deceive them, it may be possible once, but it must not be again. After suffering a loss in the hands of Tang Zheng, it is conceivable that the Heavenly God Palace will definitely be cautious about Tang Zheng.

A big organization, as long as it is cautious enough, theoretically there is no way to deceive them, after all, with the collective wisdom and efforts, the other party can think of any way you can think of.

The reason for the wrong judgment is that too many answers are equal to no answers. As a result, decision-makers tend to try to exclude unlikely answers when making decisions.

And miracles are usually built on these "impossible" foundations.

Tang Zheng stayed in the Moon Washing Academy for four years, and gradually understood the behavior patterns of this world.

When it comes to ideas, people here may be limited by the times, but when it comes to the tricks and intrigues between people, the people here are not weaker than the world where they once lived.

To say that the Heavenly God Palace would not think of using methods such as stand-ins, Tang Zheng absolutely did not believe it, so ordinary methods were absolutely ineffective against them, and only the means of incarnation outside the body could it be possible to deceive the other party.

Because in the eyes of the Heavenly God Palace, this belonged to the "impossible category" of Tang Tribulation, so they would hardly make a target for it.

Because of this, if Tang Zheng wants to create a "big miracle" that defeats the Heavenly God Palace, he must first create a "small miracle" that defeats the demon fox, and through the accumulation of countless small miracles, he will lay a great miracle in the future.

The decision has been made, and Tang Zheng has re-planned.

This time it was much simpler, and Tang Zheng quickly found where he needed it.

The dirt slope on the west side of Lao Ya Ridge.

There is a precipice and slope here, the mountains are steep, the flowing springs and waterfalls, the jungle is dense, and there are fire crow spirits scattered everywhere, the five elements have four elements, as long as you find a place that can replace the golden line, you can make a powerful formation of at least three grades. There are no ore veins on Lao Yao Ridge, but they can be replaced with materials, and Tang Zheng was prepared before he came, and brought a batch of ores over.

While finding a good location, the required circle also naturally came out.

Otogi Azure Formation.

This is a three-rank magic circle. The reason why it was chosen is because the terrain in this area is suitable for this formation. The second reason is that this formation is average in terms of killing, but it is better in terms of defense and trapping. Since it is destined not to trap all targets in the formation this time, the defensive ability of the formation itself is more important. The third is that Yiyi's flower array can be better played here.

The plan was decided, so Tang Zheng put away the map and walked towards the hillside.

With his clear eyes, coupled with his caution all the way, he didn't encounter any trouble, and Tang Zheng quickly arrived at the location and began to arrange.

Time passed little by little, the hillside was dotted with blue light, thorns were dense, the aura was slightly surging, and the water was murmuring.

Tang Zheng is like a wanderer in the mountains, wandering in the mountains, everywhere he goes, he will carefully locate and cast spells wholeheartedly, while Yi Yi is responsible for finding the fire crow essence, she is a spirit, born to deal with plants, so it is particularly convenient to find things, plus she has a clear eye, and quickly found three pieces of fire crow essence. It's a pity that the fire crow spirit on the crow ridge has found one piece less, and even if Yi Yi finds three, he can't find more.

Tang Zheng didn't care, the Yimu Azure Array didn't have much demand for fire attribute materials, as long as it could support the operation of the magic circle.

Since the scale of the circle was much larger than before, it was extremely difficult and time-consuming to set up.

Finally this time the luck was good, there were no accidents halfway, and when the sun was about to twilight, the prototype of the Otogi Azure Array had been basically completed, and the next thing to do was to supplement and improve some details.

Of course, this is also related to the small scale of Tang Zheng's current magic circle, the scale of the current magic circle is only one-tenth of the original plan, if it is according to his original plan, it will take at least seven or eight days to complete the large array that surrounds the entire Old Crow Ridge.

At this moment, seeing that the magic circle was about to be completed, Tang Zheng's mood was much more relaxed, and at this time, Yi Yi ran over, still holding a handful of white grass in his hand, and said excitedly: "Brother, look, it's Bai Fu!"
