Huangsha Island has better conditions than Dafang Island, and there are 130,000 spirit stones collected in the treasury of each family on the island alone, plus a variety of rare materials, which finally solves the urgent need of the lack of spirit stones in the sect, and makes Jia Mengzhen, who is in charge of finance, feel a little better.

In addition, there are two third-order low-grade treasure ships on Huangsha Island, which are worth tens of thousands of spirit stones, which also expands the scale of the treasure ship fleet a little.

Now in the fleet, there are already four third-order high-grade treasure ships of Victory, Crescent, Yellow Sand, and Cloud Whale, and two third-order low-grade treasure ships of White Eagle and Feiyan, which have enough strength to patrol the nearby sea.

Crescent Island is located in the north of Dafang Island, 3,600 miles away from Dafang Island, and Huangsha Islands is located in the southwest of Dafang Island, about 13,000 miles away from Dafang Island.

Although this distance was not very far for the Purple Mansion Monks, it was only about a day and a half to travel day and night. However, in the vast sea, if you want to find this archipelago, you still have to try your luck.

The last time Zhang Zhixuan went to Xuanyang Island, he took the direction of Huangsha Island, and he didn't find this archipelago, even Qingchan in the Jindan period, she didn't find the Huangsha Islands when she went to Xuanyang Island last time, although this archipelago is not too far away for her.

Therefore, in the boundless sea, the most important factor in discovering an island is luck, which has nothing to do with the monk's cultivation.

Even if it is a Yuan Infant Cultivator, the Divine Consciousness can only be released for a few hundred miles, and in the vast sea, this distance is actually very short.

For the time being, there is no teleportation array, and the two islands can only communicate with each other through the treasure ship, and it takes twelve days for a third-order low-grade treasure ship to go back and forth, and if it is a third-order high-grade treasure ship, it only takes three and a half days to make a round trip.

From Huangsha Island to Dafang Island, the treasure ships passing along the way are very rare, and near this route, there are still some demon beasts infested, and even high-level demon beasts above the fourth order occasionally appear.

Touched at the door of the house twice in a row, Zhang Zhixuan also decided to change this situation, while dispatching the three treasure ships of Cloud Whale, White Eagle and Feiyan to cruise nearby, blocking the nearby sea, he also sent a fourth-order messenger to Gu Qiwen, the captain of the Cloud Whale, so that she could notify Dafang Island at any time.

In addition, Zhang Zhixuan also planned to build an observatory on the island, install clairvoyant mirrors, and arrange special monks to be stationed there, so as not to be watched by people again without being noticed.

In addition, Zhang Zhixuan was preparing to build islands in the sea around Dafang Island and move the defense line of Dafang Island forward. He plans to turn these newly built islands into fortresses that will serve as gateways to Dafang Island. This will not only expand the land area and train more monks, but also serve as a frontline stronghold to defend Dafang Island.

The task of building an island from the sea, Zhang Zhixuan is ready to hand it over to Wan Wenhe.

There are many islands and reefs near Huangsha Island, and although they have not built islands from the sea on a large scale, they have some experience. Besides, Wan Wen and these people have been free laborers for 20 years, and Zhang Zhixuan will not let them be too leisurely.

When the situation on Huangsha Island stabilized, Zhang Zhixuan immediately recruited Wan Wenhe and others into the underground cave mansion.

Along the smooth crystal wall tunnel, Wan Wenhe and the others came to the underground cave for the first time, and instantly they felt a pure aura, which gave them a feeling of relaxation and joy.

"This must be a fifth-order spiritual vein, I said how can there be a Jindan monk on the small Dafang Island, it turns out that there is a cave heaven underground. This place must be the Taoist lineage of the previous monks, and several ancestors should be the descendants of the predecessors who built the cave. ”

Seeing Zhang Zhixuan, Wan Wenhe and the others hurriedly put away their distractions and stood aside respectfully.

"I asked you to come here today mainly for the purpose of building an island from the sea. Dafang Island, as the core of the sect, was touched to the side by others twice, although it didn't cause any losses, but our faces didn't look good. I heard that you have also experimented with reclamation of land from the sea on Huangsha Island, so I asked you to come here to listen to your opinions. ”

Everyone on Huangsha Island glanced at each other, and finally Wan Wenhe took the lead in speaking: "Although we have built islands before, they are still relatively small in scale, because the division of family interests on the island has not been discussed, so this matter has not been persisted.

However, according to our experience, if you want to build an island from the sea, it is extremely difficult to fill out an island from scratch, but it is easier to do it from the original islands and reefs. We are not familiar with the waters near Dafang Island, nor do we know about the hydrological currents, and we still need to investigate for a while before we can give our ancestors a clear opinion. ”

Wan Wenhe didn't say anything, Zhang Zhixuan was more satisfied with his cautious attitude, and nodded: "Okay!" I will lend Jia Mengzhen and others to you, and the treasure ship of Victory will also be under your control for the time being, I hope you will not let me down, and I will give you credit for a good job, so that you can get rid of slavery and regain your freedom as soon as possible. ”

Jia Mengzhen and others are natives of Dafang Island, and under their leadership, Wan Wenhe and others carefully inspected the sea surface of hundreds of miles near Dafang Island, found more than a dozen nearby islands and reefs, and selected four places among these islands and reefs to start reclamation from the sea.

Compared with ordinary people, the ability of the monks in the foundation building period is far beyond the ordinary, they dig rocks from the nearby seabed, use treasure ships to transport, and constantly fill and pile up on the islands and reefs, more than a dozen monks in the foundation building period work together, and in less than a year they built a small island with a radius of more than ten miles.

In order to strengthen the protection of the island, Zhang Zhixuan and other high-level monks also took action in person, cultivating third-order lower-grade spiritual veins on the island and cultivating some spiritual fields.

Only when there is a spiritual vein on the island, the monks can be stationed for a long time, and only then can they be regarded as having a foundation. Even if the investment is larger now, for the safety of Dafang Island, Zhang Zhixuan can only grit his teeth and do it.

Not only that, Zhang Zhixuan also built an observatory on the island, although it is easy to build an observatory, but it is more difficult to refine a clairvoyant mirror.

Fortunately, Huangyan Island collected a set of jade slips for building a third-order low-grade treasure ship, which contained the method of refining a third-order high-grade clairvoyant mirror, so that the lookout platform could be built, and it could barely monitor the nearby sea.

The third-order high-grade clairvoyant mirror can only observe a radius of more than 100 miles, but it still can't stop the prying eyes of the fourth-order treasure ship. However, with the establishment of a stronghold on this small island, the monks on the island will have frequent contacts with Dafang Island, and the monks' activities will be frequent, so they will naturally be able to block the prying eyes from many directions.

Counting the cost of cultivating a third-order spirit vein, plus the investment of the island defense formation, lookout, and clairvoyant mirror, it takes 16,000 spirit stones to build an island.

Even with such a large investment, Zhang Zhixuan still spent four years building four islands and consuming half of the spirit stones captured on Huangsha Island.

On these four islands, Zhang Zhixuan sent four foundation builders and forty-eight Qi cultivation period monks to garrison, and with the blessing of the mountain protection array, it was enough to wait for the rescue of the monks on the island.

After all, the farthest of these islands is only four hundred miles away from Dafang Island, and the nearest one is only eighty miles away.
