All the warehouses on Black Dragon Island were opened, and under the order signed by the five supervision envoys, the thirteen black dragon heads looked at the precious materials they had accumulated over the years of scraping the ground without tears, and they were moved out of the warehouses in an endless stream.

Seeing that their own treasury was constantly being emptied, the thirteen dragon heads secretly ordered to increase the cost of spiritual cultivators who had taken refuge in the Black Dragon Island. Originally, the price of a spiritual cultivator of 100,000 spirit crystals was directly mentioned by them to 1 million!

The five Ombudsmen did not react to this.

They only asked Chu Tian to arrange a powerful large array to resist Heavenly Cultivation, help them delay the pace of Heavenly Cultivation's march, and help the spiritual cultivators of the Second and Third Island Circles to gain more time to defend!

The longer they delay, the greater their credit.

As for how many materials and resources were consumed in the process, anyway, they didn't have to produce a spirit crystal by themselves, so they didn't bother to take care of it. They can't wait for Chu Tian to consume as many materials as possible, because the intuitive problem is that the more they are deployed, the more they consume, the more powerful the big array will be!

This is something that a rookie who has just come into contact with cultivation understands it!

Chu Tian was given the power to mobilize all the manpower and material resources of Black Dragon Island, he drew a detailed formation map, and ordered all the spiritual cultivators on Black Dragon Island to move mountains and reclaim the sea, change the terrain and landform, shuttle the earth veins, communicate the earth veins and spirit caves, dig ditches, and bury the great array runes......

Day and night, millions of spiritual cultivators worked day and night, the smoke and dust on the Black Dragon Island within a radius of hundreds of thousands of miles were noisy, and the mountains of spirit crystals and all kinds of rare materials were melted and filled into deep formation lines according to Chu Tian's requirements.

The large array arranged by Chutian is the 'Ten Thousand Dragons Water Intake Great Array' from the Maha Array Diagram!

This is a formation that is both offensive and defensive, and is best suited for use in marine environments.

The large array divided into tens of thousands of portals, all of which were full of mysteries and mysteries, each portal was a spiritual cave that swallowed the spiritual essence of heaven and earth, each portal was a trap that could burst out with amazing killing machines, and each portal was also an ambush with infinite changes.

What made Chu Tian happy was that the Ten Thousand Dragons Water Intake Array had no limit on its scale, as long as there were enough materials, it could cover this large array for hundreds of miles, thousands of miles, tens of thousands of miles, and even a huge island of hundreds of thousands of miles like Black Dragon Island, and it could also be enveloped in it with the formation.

And the more materials used, the wider the coverage, the more huge the water area controlled, and the more terrifying the power of the large array becomes!

Thanks to the Black Jiao clan of Black Dragon Island, and thanks to the countless spiritual forces that have continuously fled to Black Dragon Island, almost all of their savings have been invested by Chu Tian in this big array, resulting in the extremely strong foundation of this big array, and it is difficult for Chu Tian to estimate how powerful it can be.

Three days after the start of the Great Array, the huge Black Dragon Island was already shrouded in a faint layer of mist.

And at this moment, the Heavenly Cultivation Army is still a month's journey away from Black Dragon Island!

Five days after the start of arranging the Great Array, tens of thousands of huge whirlpools appeared out of thin air in the sea around Black Dragon Island, and every minute and every second, a terrifying amount of seawater was swallowed by the whirlpool, which was converted into a rich water attribute energy and hoarded in the Wanlong Water Intake Array.

Seven days after the start of the arrangement, tens of thousands of waterspouts with a diameter of miles appeared on the sea around Black Dragon Island.

The 'rumbling' waterspout is pitch black, like a pillar standing on the sea surface with a height of hundreds of miles, where the waterspout is close to the sea surface, a large area of water mist rises, and at the top of the waterspout, thick black clouds roll, the cold wind in the clouds is biting, and from time to time there are large pieces of ice crystals floating by.

As Chu Tian said, it took seven days to arrange this large array.

The next few communication formations and the adjustment of the formation layout were completely completed by Chu Tian alone.

Accompanied or 'monitored' by the five of them, including Chiyue, Ruyi, and Luo Qianchen, Chu Tian quickly entered and exited all parts of the Great Array, constantly playing one spiritual trick after another. On the earth, huge and dragon-like formations flickered rapidly, and the terrifying power of heaven and earth made everyone on Black Dragon Island pale, only to feel that a big mountain was pressing on their hearts, and it was difficult to take a breath.

Chiyue followed Chu Tian's side, and in the past seven days, she was really like a curious baby, constantly asking Chu Tian about all kinds of mysteries about the formation.

Chu Tian was not stingy, he chose the simplest formation foundation and said it to Chiyue, in fact, it meant to give it to Ruyi and everyone else. I couldn't learn any real essence in seven days, but the five Inspectors were outright laymen who really stepped into the threshold of the formation path.

Although reluctant, even Ruyi and Luo Qianchen had to admit that Chu Tian really had an extremely strong foundation in the formation.

Not to mention anything else, let's just say that this Ten Thousand Dragons Water Drawing Array gave them a great sense of threat.

They vaguely felt that if they were trapped in this great array, it would be difficult for them to escape.

On this day, Chu Tian finally completed the final debugging of the Wanlong Water Intake Array, and smashed several core array weapons refined with the Heaven Refining Furnace into the vital place of the Great Array. A cloud of water with a diameter of 1,000 zhang was suspended above his head, and in the rippling water, the sea area of Heilong Island, which was hundreds of thousands of miles in radius, was unobstructed.

The entire Great Array was under Chu Tian's control, and with the help of the power of the Great Array, Chu Tian could grasp the wind and grass within a radius of hundreds of thousands of miles at any time!

After testing the operation of the Great Array a little, Chu Tian nodded with satisfaction, the operation of this Ten Thousand Dragons Water Intake Great Array was much better than he imagined.

Of course, this was due to the countless resources donated by Black Dragon Island, and there were also reasons why those spiritual cultivators who had fled here worked hard for their own lives, but the absolute cooperation of these five overseers to Chu Tian was the biggest reason why this great array was running so smoothly.

Chu Tian really didn't expect that they were also from a big family in the spirit realm, and these five supervisors also had the unique arrogance of the children of big forces, but when they were really doing serious things, their performance was really beyond Chu Tian's expectations.

If it were Luo Jianlin's kind of brain-dead, I'm afraid he would have fought with Chu Tian a long time ago, right?

I really didn't expect that Ruyi, who was so stimulated by Chu Tian's words, could calmly cooperate with Chu Tian to arrange the formation these days, without any hindrance or deliberate embarrassment.

Shaking his head, Chu Tian sincerely praised the five of Chiyue and Ruyi: "I really didn't expect that the performance of the five supervision envoys was far beyond the imagination of this seat. In particular, the Ruyi Inspector ...... Hey, I have to admit that a few days ago, my words were a bit excessive. ”

Ruyi's eyes swirled, and he glanced at Akatsuki quickly.

She suddenly opened her mouth and smiled: "What did the layman say? What is the small verbal dispute between Ruyi and the layman? I don't know, in the future, the layman will have the will to join the sect? My Tianya Pavilion is willing to worship the layman as an elder!"

Chiyue's eyebrows raised, and the faces of Luo Qianchen and the others changed at the same time, and they all spoke, wanting to recruit Chu Tian for their own sect.

At this moment, on the extremely far sea, a ray of fire rushed into the sky, and then exploded violently.

It was the sentinel sent by Black Dragon Island, and they had already made contact with Tianxiu's outpost force.
