In the next two days, the spiritual pressure of the second peak in the south continued to be tested, and a large amount of data was obtained around eight directions.

Nanwu Prefecture is surrounded by two mountain groups, the North Mountain Group has seven peaks, covering the northwest, due north, and east directions, and the South Mountain Group has five peaks, forming a barrier in the southwest and south, and the two mountain groups surround the central valley forest covering an area of 360,000 acres.

After testing the South Second Peak, the Lingyuan Dao Leader spent another six days testing the peaks in the rest of the South Mountain Group. After finishing, he asked Gu Zuo: "There are two ways to arrange the formation, one is to cover the southeast of the south main peak, the second peak and the third peak into the formation, and the other is to lay out the south two peaks separately, which one does the Gu Pavilion master choose?"

"Three-Element Extreme True Array, does it have such a large enveloping range?" Gu Zuo was a little surprised.

There is also a Water Heaven Xuanyuan Array on Gengjin Mountain, but the enveloping area is less than 800 acres, which just covers the whole mountain. The South Second Peak is a big mountain, covering an area of 10,000 acres, Gu Zuo originally thought that it would be good if the Sanyuan Extreme True Array could cover the waist of the peak, but he didn't expect that in the alternative plan proposed by the Lingyuan Daoist, it actually included more than half of the South Main Peak and the South Third Peak, and this place could be connected to more than 38,000 acres!

The Spirit Source Dao Master immediately explained to him.

The Three-Element Extreme True Great Array is a top-level magic array, and stabilizing spiritual pressure is only one of its many effects. If there is no spiritual power here, its coverage area is about three times that of the Shuitian Xuanyuan Array, that is, about two thousand acres, but if the formation is placed on the spiritual stone veins, it can be expanded by ten times or twenty times.

According to the data measured by the Lingyuan Dao Chief, two methods can be adopted, one large and one small, and there is not much difference in mining spirit stones. The difference in the scope of the envelope is mainly to consider the effect of the circle itself. The larger the place, the more protected the place, and the smaller the one, the corresponding loss of spirit stones is much lighter.

The Three-Element Extreme True Array has nine nodes, if you choose to lay it out in a small area, it will consume more than 360 spirit stones per year when mining spirit mines, and when activating the protective effect of the large array, each node will consume one spirit stone per day, and if you turn on the killing array effect with all your might, each node will consume one spirit stone every hour.

If you choose to lay out in a large area, when stabilizing the spiritual pressure, the consumption of spirit stones is no different from that of small areas, which is also a total of more than 360 spirit stones per year. However, if the protection or killing array effect is activated, the consumption of spirit stones will be three times that of a small area.

After all, Nanwu Prefecture is in the south of the Black Mountain Zhao and faces the front line of Southern Xinjiang, so the Lingyuan Dao Chief must consider the protection ability when arranging the formation.

Gu Zuo was also thinking about this issue, and he couldn't ignore the letter that Jiang Xiaozhu left for him that day. Of course, he wanted to expand the scope of the magic circle, preferably the entire Southern Wu Prefecture, but this was not realistic.

Therefore, after careful calculation, he still chose the latter option. Assuming that the beast tide really breaks out next year, and assuming that the beast tide really arrives in Nanwu Prefecture, he must consider the duration of the big array.

According to the scale of the beast tide six years ago, it lasted for about three months, and in the case of choosing a large-scale array, it meant that the normal protection consumption of the magic array was two thousand seven hundred spirit stones. But this is only protection, it is not lethal, it is too passive, and when facing the impact of high-level monsters or a large number of monsters, it is necessary to turn on the killing array function, and the light protection will definitely not be able to resist without counterattacking.

And when the magic circle counters to kill, it consumes twenty-seven spirit stones in one hour, if it is used once a day, the consumption will increase by two thousand seven hundred pieces in three months, if it is encountered twice, it will increase by five thousand four hundred, and if it is extreme, it will increase three times, it will be eight thousand one hundred pieces!

Even if you don't use it like this while guarding the spirit stone vein, it's not worth doing it.

If you choose a small-area formation, the consumption is only one-third of that of a large-scale formation.

Therefore, according to his request, the Lingyuan Dao Master only wrapped the South Second Peak into the magic circle. As for the main peak and other places, if you really want to encounter the beast tide, you can only abandon it.

Before laying it out, Gu Zuo deliberately asked the Lingyuan Dao Leader to go to the hillside to measure the spiritual pressure again, and the data from this test made the Lingyuan Dao Leader fine-tune the layout plan of the magic circle. He said thoughtfully, "There may be a mine down here." ”

Deacon Shang said to Gu Zuo proudly: "How? Listen to me, right? My dragon search and cave exploration technique is famous!"

Of course, Gu Zuo praised Deacon Shang, to the effect that "you are old and smart, Huaixian Pavilion needs you, and Southern Wuzhou needs you", which made Deacon Shang happy and complacent.

On December 20, the Huaixian Pavilion began to lay out the Three-Yuan Extreme True Array, and according to the pre-marked data, the eighty-one sub-arrays were driven into key directions.

Every nine sub-arrays form a small array, every three small arrays form a sub-array, and three sub-arrays form a large array, wrapping the South Erfeng in the array.

I was busy until late at night, and the whole set of array disks was completed, and a monk was arranged at the nine nodes to control them, embedding the spirit stone into the hole slot, and Gu Zuo started the large array compass in the center, and suddenly, the red, yellow, and blue three-color Xuanguang rose in the sky above the South Second Peak, unpredictable, and dazzling.

Everyone was shocked by this scene and looked up greedily. Deacon Shang sighed: "The Huashan Xixuan Sect is worthy of the world's great formation sect, and my Dongting Sect is ashamed of itself......

Gu Zuo was overjoyed in his heart, and said: "The Dongting Sect has a high cultivator sitting in Southern Wuzhou, and our Huaixian Pavilion is not strong, so we can only rely on this big array." ”

While observing the big array, Gao Changjiang buried his head in the description of the formation provided by the Huashan Xixuan faction, and said, "It seems that there is a bit of a deviation, and the old man suggests testing the killing formation." ”

This was inevitable, so Gu Zuo handed the compass to the butcher. The butcher is a Jindan monk, and he can control it in order to exert more power in the big array. In fact, the highest cultivation in the field is Deacon Shang, but unfortunately Deacon Shang is not a monk of Huaixian Pavilion, so in order to avoid suspicion, he hid aside.

The butcher took the compass, fed his true qi into the compass, and after being familiar with it for a while, he began to exert his strength.

The Three-Element Extreme True Great Array immediately began to change, and as the butcher continued to exert force, there was even a buzzing sound, and the entire South Second Peak began to tremble slightly.

The original brilliant and dazzling three-color brilliance in the night sky began to blend, gradually fading its true color, looking up from the bottom up, the sky full of stars disappeared, and the night sky was deep and intimidating.

But there is still instability, in the deep night sky in the northeast, there is a faint blue light passing through.

Gao Changjiang is worthy of being a master of construction, although he is interlaced, he can find problems in advance, and with this vision alone, it is not expensive to pay him and his disciples an annual salary of 1,600 yuan!

As a result, Daoist Lingyuan began to re-examine the data, and at the same time, he also began to consult Gao Changjiang's opinion. The two discussed for half an hour and began to adjust the layout of the array plate, adjusting it three times in a row. By the time of the third test of the killing array, there was no more stray light in the sky, only endless darkness.

The three-element extreme true array has been successfully deployed!
