On this kind of unfamiliar island, Zhang Zhixuan and the three of them were more cautious, because of the language barrier, they did not dare to communicate with the islanders easily, so they could only hide in the dark and observe every move on the island.

Sunrise and sunset, spring goes to autumn, and it has been three years since the three of them teleported over in the blink of an eye.

In the past three years, Zhang Zhixuan and the three have been hiding in the dark, while cultivating in the underground cave, while relying on invisibility charms to learn the local language and writing, and by the way, the surrounding situation is investigated.

This deserted island is called Dafang Island, which was just a desert island more than 300 years ago, because the center of this island is solid, and there has been no earthquake for thousands of years, and it was selected by Liu Xuanyan to build an underground cave.

After the underground cave was built, Liu Xuanyan rescued some monks by the way and supported them to gain a foothold on the island. Because of the leakage of the underground spiritual vein, a spiritual vein was gradually formed in the center of the island, and it also attracted some loose cultivators who failed to compete nearby.

After years of operation, these people have cultivated the spiritual veins on the island to the third-order upper grade, and the spiritual energy is already quite good.

Up to now, there are seven monks in the foundation building period and more than 300 monks in the qi cultivation period on the island, and these monks have multiplied and have formed seventeen monk families.

These seventeen families live together on the same island, because of limited resources, of course, there will be fights, but in the face of foreign enemies, they can put aside contradictions, unite with the outside world, and resist external humiliation.

In the last three years, Zhang Zhixuan has witnessed a fierce battle.

The monks of Dafang Island united to fight off the invasion of a small treasure ship and defend their portal.

In this battle, more than 40 monks died in the Qi training period on the island, and even the monks in the foundation building period also lost two people and wounded three people.

The environment of Qinglihai is different from that of Nanyazhou, where the vast sea is everywhere, and scattered islands dot the sea.

Most of these islands, large and small, are desert islands, and only some of them have spiritual veins, which are suitable for monks to garrison.

The stronger the spiritual vein on the island, the more powerful the monks can be cultivated, the more advantageous the position they can occupy in the competition, and the more they can strengthen the sect and develop the family.

Therefore, in the Qingli Sea, in order to compete for Lingdao, very cruel and fierce battles often break out.

Because of the long distance between the islands, except for the main spirit veins controlled by the big sects with teleportation arrays, most of the spirit islands communicate with each other through treasure ships.

The treasure ship uses spirit stones as an energy source, combined with countless rare materials, and it is extremely difficult to refine, often requiring dozens of cultivators such as refiners and array mages to cooperate with each other, and it takes a lot of time to refine.

Refining a small third-order treasure ship costs more than tens of thousands of spirit stones, which is much more difficult than cultivating spiritual veins.

Compared with the popular spirit boat in Nanya Prefecture, the treasure boat has many advantages and specific disadvantages.

A small third-order treasure ship can carry at least a thousand people, and the internal space is far more than Zhang Zhixuan's fourth-order spirit boat, the Floating Cloud Boat, which is better at transporting goods than whale beasts.

Secondly, the construction of the treasure ship uses a lot of materials, not only the space is large, but also very strong, which can resist the violent wind and waves at sea and the terrifying beasts underwater.

Without a treasure ship to go to sea to escort, ordinary ships can't leave the island at all, even if they barely go to sea, they are easily attacked by monsters in the sea, and a ship will be destroyed and people will die.

The environment of Qinglihai, except for the huge island occupied by the monks of the Yuan Infant Stage, is like a vast continent, and there is no shortage of land itself, which can open up countless fertile fields for self-sufficiency.

Ordinary small islands are limited by the size of the islands and simply cannot support too many people.

For example, Dafang Island had a population of more than 30,000 three years ago, but the land on the island was insufficient, and there were no drawings for building treasure ships, so it could not go to sea to obtain resources, so it could not support too many people.

Nearly two hundred years have passed, and the number of mortals on the island has not increased much, but the number of monks has increased a little, and there are a few more monks in the foundation building period. As a result, a great war returned to the original point, and hundreds of years of hard work were in vain.

The reason why Dafang Island has been able to develop to this point is that the exercises on the island have been inherited well, inherited from a very powerful predecessor three hundred years ago, and the first few monks on the island in the foundation building period received the help of her old man.

The second is to absorb a large number of loose cultivators who have failed in competition, and the competition for Qingli Hailing Island is very common and cruel.

If a spirit island that is developing very smoothly is unlucky, if it encounters a powerful demon beast or a large treasure ship, it may be accidentally crushed, lose the spirit island where it has a place to live, and become a loose cultivator.

The rules of Dafang Island come and go freely, and these monks who fail in competition can easily integrate into the island. There are constantly foreign monks entering the island to improve their bloodline, which leads to the fact that the bloodline of the island's population is getting better and better, and an average of a hundred mortals can give birth to a child with spiritual roots, which is far more likely than the Nanya Prefecture Xiuxian family.

The Zhang family and the Liu family have a population of more than 300,000 people, and the monks they have cultivated are only 400, and the population of this small island is only 30,000 or 40,000, and the monks on the island are only a little less than the Zhang family.

If there are no foreign monks to improve their bloodlines and intermarry with the population on the island, the bloodlines of the mortals on the island will become worse and worse, and they will gradually return to the ordinary, and after one or two hundred years, they will lack stamina.

The treasure ship is not only large in space and very strong, but the speed of sailing is not weaker than that of the spirit boat flying in the sky, but compared to the spirit boat flying in the sky, the treasure ship can only sail on the water and can only be anchored in the harbor.

Moreover, the spirit boat can be enlarged and reduced, stored in a storage bag, and even used as a natal weapon to refine into the dantian for warmth. Once the treasure ship is refined, it cannot change its shape, let alone reduce its size, and it is stored in a storage bag, and it takes a lot of manpower to move and operate.

Compared with the spirit boat, this is the biggest shortcoming of the treasure boat.

In addition, the treasure ships have refined extremely powerful magic weapons, as well as special formation protection, which can give full play to the advantages of a large number of people, gather the mana of many people, and often be able to defeat the strong with the weak, and defeat the masters who are far superior to themselves.

A third-order high-grade treasure ship usually carries three fourth-order god-destroying crossbows, and the god-destroying crossbow uses medium-grade spirit stones as an energy source, and the crossbow arrows fired are not weaker than the six-yang demon destroying crossbow used by Qingchan back then.

If the foundation building monk is not careful, he may be killed by a single blow. Even the Purple Mansion cultivator, who was attacked by the three-way and fourth-order god-destroying crossbows at the same time, had to be in a hurry, and if he didn't cultivate enough, he might break his muscles and bones.

As long as the spirit stones carried on the treasure ship are sufficient, a third-order high-grade treasure ship needs to be stationed with five foundation building and thirty qi cultivators, and it can compete with one purple mansion.

Of course, a third-order high-grade treasure ship is definitely not an opponent of Qingchan, and it can't beat a great master of the Purple Mansion period like Zhang Zhixuan, and it is not even an opponent of Hanyan, but when he encounters a monk like Wei Bohan in the early stage of the Purple Mansion, he can compete with it until the spirit stones on the treasure ship are exhausted.
