In the case of seeing Fu Dan in the late stage, these two people did not get out of the way at the first time, but stood side by side in the center of the passage, and held a small purple flag in their hands, once there was any problem, they would re-block the formation as soon as possible.

In this regard, the gray-robed Commander Chen Qianfu had long been surprised by this, and the red beads in his mouth were spit out by him, and at the same time, the object in the hand of the Huagen Realm standing in the middle of the passage lit up, and the two of them respectfully let go, and Captain Chen swallowed the beads again.

"This thing is called the Divine Pearl, which is exercised with the unique refining technique of the Holy Fire City, divided into the mother bead and the child bead, you will also get a piece of this after you go in, first leave your own divine soul mark on the bead, and then as long as you use the divine mind to destroy the child bead, the corresponding mother bead will be lit, and any other way will not make the mother bead light up, and this is the only permission to enter and exit here, don't lose it when the time comes, otherwise it will be very troublesome. ”

After the two of them flew in, the passage merged again, in fact, the sea fog did not shroud the entire island, but a transparent shield about ten zhang above the base divided it, and countless Gathering Spirit Transformation Root Realm Spiritual Cultivators flew around in it, and from time to time, there was also a flash of Fu Dan's escape.

It was also the first time that Zhang Hai had seen how spiritual cultivation built a city.

The three spiritual cultivators stood in a row, first a Hui Ling Realm took out a palm-sized gray bag from his waist, and with both hands, countless black sand flew out from inside, and at the same time, several spiritual determinations came out, and these sand gathered in the middle, and soon a black brick with a height of one person was formed, and it was placed on the city wall that was still under construction, at this time, another Hui Spirit Realm would fly over and solidify the spiritual art on the actual combat, and after making sure that it had been stabilized, the third spiritual cultivator would fly out and pour out all kinds of materials from the storage bag and refine them into the bricks, and then refine them, and suddenly the original black brick surface began to have golden lines, which were integrated with the city wall below。

In this way, a piece can be considered paved, but the speed of spiritual practice is amazing, and it is often possible to complete a piece in a few breaths, and the progress is not bad.

In addition to these, the array mages began to carve the forbidden on the walls that had already been built, and the refiners were installing and building the weapons to defend the city, everything seemed busy but orderly.

And these are just the tip of the iceberg, the scene below the sea surface will be even worse, but if you want to work on the bottom of the sea, the cultivation is at least the cultivation of the root realm, and at the same time, it is also the most difficult to defend and the most ferocious place for the sea tribe to attack, after all, this is not a real island but a floating island built by spiritual means, and everything starts from scratch.

"I'll take you to get some of the materials you need first, and first learn how to arrange the "Nine Yuan Three-Point Array" here, and then I'm afraid I'll have to go to some islands ahead to arrange the formation, and time is running out."

Simply speaking, the gray-robed old man took Zhang Hai to a temporary stone hall, which was heavily guarded, and Zhang Hai saw three or four of them in the Fudan Realm alone, and when he approached, he even felt the undisguised divine thoughts of the Manifestation Realm! Obviously, there was at least one Manifestation Realm guarding in the main hall, thinking about Captain Chen's previous return to the Holy Fire City to collect materials, it is estimated that this is a place for resource hoarding, no wonder the guards are so cautious.

Escape stopped at the main entrance of the main hall and did not enter.

"You wait here first"

After dropping a sentence, Commander Sun Qianfu walked directly into the main hall, and it took about a cup of tea to come out again, and there was an extra gray storage bag in his hand.

"You are new here, the materials issued by the Holy Flame City have not been taken, in addition to this, there are also nine yuan three-point array diagram and some experience, I will give it to you, you take advantage of this time to study, I may come over a few times in the middle, if you have any questions, you can ask me at that time, of course, you must remember not to pass it out easily, otherwise don't blame my subordinates for being ruthless"

Captain Sun Qianfu said with a warning taste, and at the same time handed the storage bag in his hand to Zhang Hai, and then took Zhang Hai to a building to serve as a temporary cave house, where he could live if he had nothing to do during the establishment of the whole new city.

After explaining some things, Commander Chen left in a hurry.

Entering the stone house and glancing at the place where there was nothing special, Zhang Hai took out the storage bag that Commander Chen handed over to him, there were only a few things in it, a piece of Sacred Fire City clothes, a piece of jade, and a thing like a leaf.

The first thing Zhang Hai took out was the thing that looked like leaves, this is the famous phoenix feather talisman, the fallen leaves of the phoenix plane tree, and the lines in it are natural.

Curious, he turned it over for a while and couldn't see anything, so he took it back, picked up the jade slip and pasted it on his brow, and a formation came to mind......

For the next time, Zhang Hai was closed in the house, and there was a dream space, even if there was a difficult formation, it would not be too much of a problem for him, but he was not sure if Commander Chen had sent someone to secretly observe him, if he just gave the other party an image of his own arrogance just because of curiosity, it would really be worth the loss.

No one came to take care of him for two months, until the third month later, Captain Chen came over, and the gray robe was just his eyes red at this time, even if he was a profound cultivator, he couldn't hide his exhaustion, and asked Zhang Hai a few questions about the formation at random, Zhang Hai answered them fluently, and even asked a lot of in-depth questions, he had already been completely familiar with the entire nine-point three-element array in the dream space, even if there was something he couldn't figure out, he could overcome it with the notes given by Commander Chen, and asked a few questions just because he didn't want to be too eye-catching。

Even though the whole person was extremely tired, Commander Chen still patiently explained to Zhang Hai one by one, and said that he was very satisfied with his progress, at most one more month Zhang Hai would be able to lay down this nine-yuan three-point formation alone, according to the news from the front-line scouts, there was another large branch of the Sea Clan coming from the deep sea, and the first wave of beast tide would break out in a year at most, but now there are many islands in the strongholds on the front line that have not been arranged to guard the prohibition, as long as they are slightly separated by spirit beasts. Many of the guards were dissatisfied, they were not here to build the new city, not to die, although it was not a long-term solution to be suppressed.

However, it is really difficult to mobilize manpower on the side of the Holy Fire City, and the matter of the spirit mine is very troublesome, due to the negligence of a Fu Dan realm spiritual cultivator, which leads to problems at key nodes, and afterwards delusions that one person can solve it and eventually leads to problems in several other places, and even has to borrow formation mages from some other major sects, and they are sleepless to remedy, so everything can only rely on themselves, if Zhang Hai can lay out the formation alone, at least settle a stronghold before the beast tide arrives, if it is smooth enough, it is not impossible for the two, it will relieve a lot of pressure。

This is also the reason why he ruled out public opinion and let Zhang Hai, a newcomer, take on such an important role.

......

A month later, more than a dozen people flew out of the Xincheng base in a low-key manner.
