Forty dragon pillars are in place, each erected in a formation according to the feng shui trend determined before, the roots are thick, straight through the clouds, the scene is magnificent.

Each refining team began to add materials to the dragon array they refined, one of which was the wind spirit liquid, and the other was the spirit stone.

The difficulty of tackling the wind spirit liquid is very high, but it is not expensive, but the amount required is large, and each launch requires eight thousand catties, of which each dragon pillar needs to be poured into two hundred catties.

The most expensive is the spirit stone, and the base of each pillar needs to be stored with 3,600 pieces, and all of them will be consumed in one launch.

Deacon Gu solemnly handed over the array plate to Gu Zuo and said, "Please ask the hall master to try the array." ”

What Gu Zuo held in his hand was a round Tai Chi ball held by one person, and with a gentle lift of the Tai Chi ball, the void floated in front of him, slowly turning. It's just such a Tai Chi ball, filled with six thousand spirit stones!

There is a special refining team of nine people in Nanwu Prefecture who keeps refining wind spirit liquid, and has already reserved 100,000 jin so far, and the reserve number of spirit stones is 2.15 million. With the current stock, it is only enough for the Great Array to be launched twelve times.

To complete a trial formation, it would require eight thousand catties of wind spirit liquid and one hundred thousand spirit stones, which was really expensive and extravagant. Gu Zuo was heartbroken about this, but he also knew that this was a must-pass, and he still had to try.

After the wind spirit liquid and spirit stones were filled, there were only forty Jin Dan left in the field, one person to take care of a pillar, record data at any time, or call a stop to the trial formation when the pillar was in danger, such as when it was about to explode.

The rest of the people all cleared out of the square and stayed away from the dragon pillar.

When the personnel were in place, Gu Zuo stroked the Tai Chi ball with both hands, and explored the spiritual energy circulation veins in it between rotations, and searched for the spiritual power nodes corresponding to the forty dragon pillars.

This scene Gu Zuo was very familiar with, it was very similar to his qi sea, he could now sense more than nine hundred and twenty true qi feedbacks in his qi sea, including Elder Shang, the Yuan Baby, the butcher and other seven golden pills, which was much more complicated than controlling the array disk.

Gu Zuo was familiar with it and started one by one.

The first dragon plant made a buzzing sound, and the top dragon head spewed smoke into the sky, followed by the second and third, one by one. When the forty dragon pillars were opened at the same time, the smoke from the spews accumulated into thick clouds in the sky.

The clouds suddenly expanded into a transparent wind blade in all directions, enveloping Nanwu Prefecture, the wind blade was like a knife, and began to cut along Nanwu Prefecture, smashing all the rocks and trees it encountered, and drawing a trench three feet deep on the ground!

Gu Zuo controlled the array disk, and did not let the wind blade continue to cut downward, but just tried the formation, and did not need to go deeper.

Forty Jindan monks began to quickly record the dragon pillars they cared for, checking the integrity of each kit, inspecting the condition of the fusion place, and feeling the heat of the pillar.

On the periphery, there was a pre-arranged survey group that looked along the trench cut by the wind blade and drew the route on the map of Nanwu Prefecture.

The trial process of this step lasted for a long time, totaling about an hour, because after breaking the boundary, I don't know what situation I will face, and I still need wind blade protection. The set protection time of the large array is one hour, and after an hour, the wind spirit liquid will be exhausted, and it will be protected by the four heavenly capital arrays, and the spirit stones required are only one percent of the Lianshan Taiji Panlong Array. Of course, the protection capacity will also be weakened by one-seventh.

After waiting for half an hour, the monks who took care of the dragon pillar summarized and reported the data for the first time, and after another two moments, Deacon Gu told Gu Zuo about the situation: "There is something wrong with one of the pillars, and the angle of the smoke at the dragon's head is wrong. ”

Gu Zuo asked, "Who refined it?"

Deacon Gu said: "Kusang Dao people. ”

Gu Zuo nodded, it was him who came out of the moth last time, and this time it was him, I don't know what the reason was, I'll find out later.

"Does it affect the Great Array?"

"The impact is relatively small, it is under control, and it can be continued. ”

The effect of the wind blade can be checked one by one after each dragon pillar is refined, so it is not a big problem, the key is the next two levels.

The wind blade continued to envelop Nanwu Prefecture, and Gu Zuo turned on the second major effect, loading.

In an instant, the wind shield began to cut downward, and the trench that was originally three feet deep began to gradually go deeper, and the entire Nanwu Prefecture began to shake like an earthquake.

Five feet, one zhang, three zhang......

The monks who circled the outer measuring trench rushed back and forth, constantly reporting their depth.

Five, ten, fifteen......

It can no longer be called a trench, it is more appropriate to call it a deep stream, which is different from the Zhongnan Mountain in the north, where the water source is abundant, and the ground has begun to overflow.

When it was almost thirty zhang deep, several Jin Dan who were taking care of the Panlong Pillar stretched out their hands at the same time, shaking constantly, Gu Zuo stopped, looked at Deacon Gu, and Deacon Gu rushed over to check them one by one.

After a while, Deacon Gu came to Gu Zuo and said, "The pillars of the six dragon pillars are starting to get hot, I tried it, and within tolerance, I can continue." ”

So, Gu Zuo continued to urge the big array.

Forty zhang, fifty zhang, sixty zhang......

At this time, the measurement was carried out with an iron needle, and the measured data was not accurate, and it was necessary to wait for the end of the test array, and then the Jindan monk would put on a water-avoiding cloak and sink to the bottom of the deep stream to see clearly.

When it was about eighty zhang, the sound of the wind blade cutting suddenly became sharp, extremely harsh!

Deacon Gu and Daoist Elder Jinghong both rushed into the big array, and at the same time, there were also two elders of the Huashan Xixuan Sect, Su Fen of the Su Immortal Pavilion, Elder Lu of the Eight Formation Gate of Pingdu, Elder Lin of the Nanhua Sect and other formation cultivators.

Several people hurriedly finished inspecting, and they all signaled to Gu Zuo that there was no problem. Two Jindan monks who were measuring the depth on the periphery rushed in and shouted, "Heptane Iron Ore!

It turned out that the wind blade had cut into a Gengjin iron ore deposit underground! Lingyuan Dao Master was relatively proficient in mineral deposits, so he hurriedly rushed over, and he didn't come back this time, but just sent someone to spread the word that it was a rich mine.

The discovery of Gengjin iron ore was an unexpected joy, Gu Zuo ignored it anymore, and continued to urge the big array, when the wind blade was cut to a hundred zhang, the clouds in the sky gradually became unstable, and the pillars of the forty coiling dragon pillars also began to turn red.

Deacon Gu and the others waved desperately to Gu Zuo, but Gu Zuo didn't dare to push down any further, so he could only sigh and withdraw his hand. The deepest part of Zhongnan Mountain is 160 zhang, the shallowest part of the periphery is more than 130 zhang, compared with the two, the depth of the subcut of Nanwu Prefecture is less than 20%, and the deepest part of the center of the ground may be about 12 or 30 zhang.

It is still because the array is not up to par, compared with the Lianshan Taiji Panlong Array refined by the Chongxuan Administration, the refining level of Southern Wuzhou is a lot worse.

Fortunately, nothing happened, although Gu Zuo was not sure if he could take away the entire spirit stone vein, but after all, in a sense, the second major effect of the magic circle was successfully achieved, although the index shrank a lot.

Now it's time to test the all-important boundary-breaking effect.
