After gathering all the materials and gathering enough manpower, the super array that enveloped the entire Yanling City began to be built, and Li Jian and the others also led a huge number of array mages to command outside the huge Yanling City.

Yanling City is extremely huge, so the entire super array project is divided into hundreds and teams to work together, each team has at least ten array mages to command, leading a certain number of human and sea clans to dig and depict the formation on the ground, and the demon beasts of the demon clan are responsible for transporting materials.

Outside Yanling City, a huge demon beast on the ground came and went, and a huge number of birds and monsters in the sky were constantly flying back and forth, like dark clouds pressing on the top, and the roar shook the sky when they came and went, and each demon beast was carrying a large number of cultivation materials.

Ten days later, outside the entire Yanling City, the ground is full of ravines extending in all directions, each gully is dozens of zhang deep, in the depths of those ravines, you can vaguely see a lot of light, look carefully, you will find that it is a piece of the best material that exudes a variety of energy luster, those superb materials, each piece is precious, contains huge energy, and at this time, it is only like a foundation, is paved underground.

If someone looks down at Yanling City from the sky, they will find that the ravines that appear around Yanling City are all extremely complex and cumbersome patterns, and these patterns cross out very mysterious patterns on the ground, and at intervals, between those mysterious patterns, a pure black or pure white altar will be placed, which is the Yin and Yang Altar.

In the formation diagram, the martial artists of the Innate Realm are responsible for digging those ravines. This job is the most tiring, so they are constantly coming in and out one by one. Sweaty and slightly pale.

The martial artist of the Gathering Peak Realm is responsible. It is under the guidance of those array mages that specific materials are placed in a specific position accurately, and then arranged neatly.

The martial artists of the Guiyuan Realm are responsible for depicting those more detailed formations, and this kind of work cannot be wrong, so it is more labor-intensive, so those who cultivate a little lower will not be able to do it.

The group of psychic realm warriors are responsible for completing the work of connecting the formation maps between each team and the other team's formation map. This work is more detailed, and it also needs the supply of spiritual power from time to time, so a group of psychic realm martial artists have become a reserve team, and where the formation map needs to be connected, they will immediately go to that place.

In the end, the work of placing the Yin and Yang altar was completed by Li Tianhong himself. Lan Yunzhen is in charge of logistics, whenever someone is exhausted and exhausted, she can go to her to get the right pill to speed up recovery. The division of labor is meticulous, so almost everyone has become a craftsman, and they are all busy and dedicating.

It's just that. When the ground formation was being built, Li Jian and those martial artists who had cultivated to reach the Imperial God Realm were all gone, and no one knew what they were busy with. It's just that every once in a while, everyone will feel a strong wave of power from the sky above Yanling City.

This construction is in full swing. It lasted two months, two months later. Around the entire Yanling City, dense ravines are densely packed, surrounding the entire Yanling City.

After the prototype of the super array came out, Li Yan began to get busy, because the eighteen yin and yang altars were all under his control, so after the formation map on the ground was completed, the eighteen yin and yang altars must also be activated by him.

After two months, the super large array on the ground was finally completed, and the eighteen yin and yang altars were placed around the entire Yanling City in a circular shape like the array on the ground, and after the yin and yang altar was placed, as soon as Li Yan activated the yin and yang altar, the energy contained in the superb materials engraved in the array on the ground would be continuously poured into the yin and yang altar along the pattern, and then the pattern full of energy, just by looking at it, it would make people's hearts sway, as if it had some kind of magic.

Of course, Li Yan's work is not just as simple as activating the Yin Yang Altar, he also needs to make the Yin Yang Altar, the ground formation map and the underground Xuanyin Qi and Pure Yang Qi all linked, this work is very energy-consuming, after each place, Li Yan's whole person will be tired and exhausted, his eyes are a little broken, and he is constantly supported by pills and various spiritual objects, day and night.

Eighteen days later, the eighteen Yin Yang Altars were all activated, and the array on the ground was all hidden under the power of that mystery, and it became difficult for the naked eye to see, and under the effect of the array diagram, the eighteen Yin Yang Altars not only connected the Yin and Yang veins under the Yanling City, but also transformed them into pure energy and fed back to the cultivation area of the Yanling City, creating a better cultivation environment for the martial artists of the entire Yanling City.

When the super large array on the ground was completed, where people in the sky could not see, nine huge silver portals also surrounded the entire Yanling City in a circle, and these nine silver portals were the nine heavenly gates of the foundation of the Nine Gates Heavenly Palace Great Array after being refined.

At this time, the nine Heavenly Gates stood in the void, and above each Heavenly Gate, there were countless fine enchantment prohibitions, which connected the nine Heavenly Gates together, and shrouded the entire Sky of Yanling City.

Among the nine Heavenly Gates, each Heavenly Gate has a Imperial God Realm martial artist who is responsible for urging the power of the Heavenly Gate, and in the center of the Nine Heavenly Gates, Ji Qingying is sitting in the air, and under the echo of the Nine Heavenly Gates, the surrounding heaven and earth qi is also constantly attracted and poured into the Nine Heavenly Gates.

"Boom!" Just when the nine Heavenly Gates were completely linked together, the Nine Heavenly Palace Great Array, which was based on the Nine Heavenly Gates and supplemented by countless enchantments, prohibitions, and small formations, was also officially launched.

The control of the Nine Heavenly Gates Li Yan was handed over to Ji Qingying when he was in the Xiaoqian World, so the work of rerefining has always been in charge of her, in order to refine the nine Heavenly Gates, this period of time almost exhausted all of Ji Qingying's energy, at this time, the Nine Gates Heavenly Palace Great Array was completed, and she was the one who got the most feedback, when the endless Heaven and Earth Qi was fed back, Ji Qingying, who was in the center of the Nine Gates Heavenly Palace Great Array, was instantly overwhelmed by the huge Heaven and Earth Qi, and the whole person exuded a brilliant colorful light.

"Nine Gates Seal Tianyuan!" Suddenly, Ji Qingying in the sky suddenly opened his eyes, and then his handprint changed, and he let out a cry in his mouth, and suddenly, a dazzling light erupted above the nine heavenly gates at the same time, rushing straight to the ground from the sky!

"Yin Yang Town Place!" Below, Li Yan, who was standing in the center of Yanling City, also changed his handprint after seeing the light falling from the sky, and his mouth exploded, and a thousand rays of light suddenly poured out from the ground and rushed to the sky. (To be continued......)
