Treasure Island is in the Luoxinghai Islands, which already belongs to the rear, and the island area is much larger than that of Dajin Island, with a radius of about 20,000 li, which is one-third larger than that of Lu State.

Originally, there were five major forces on Treasure Island, and the highest spiritual vein on the island had been cultivated to the middle grade of the fifth order, but this spiritual vein was in the middle of the island, and it did not have a great effect on the defense of the entire Treasure Island.

Today, the defense of Treasure Island is mainly in three cities not far from the coastline, located on Treasure Island in a zigzag shape, and the nearby mortal villages and towns have long since moved, and there is not a single mortal within two thousand miles of the coast, and there are barren farmland and empty villages everywhere.

Lin Xiao retreated for three months, and after three months, Lin Xiao's cultivation was promoted to the seventh layer of Daogang, and then he went to the Luo Xinghai Alliance in Chijin City to report.

"Congratulations to Xiao Daoyou for cultivating to the next level"

"The fall of Dajin Island has humiliated my monks, so don't make fun of me."

"Xiao Daoyou doesn't have to be like this, the demon clan is powerful, this is a helpless thing"

"Okay, I'm tired of Daoist friends, let's check how the merits are below."

"Xiao Daoyou, wait a minute"

Lin Xiao took out his token, and the Lingering Stone had already been handed over, so it was time to check his exploits, after all, Luo Xinghai came here for this.

"I found out, Xiao Daoyou is a fourth-order array mage, sitting on Dajin Island, with three thousand merits a day, a total of four months and seventeen days in Luo Xinghai, and the basic merit is 411,000 points, in addition, Xiao Daoyou is brave and invincible in the breakthrough battle, killing countless enemies, and the total number of merits is about 630,000, and the total number is 1046,000 points.

According to the rules of the alliance, merit points are equivalent to Xuanjing, if Xiao Daoyou needs to advance in advance, you can cash Xuanjing to you, or equivalent spiritual material resources can also be, here is the catalog of merit exchange"

After checking it, the steward said to Lin Xiao, and he was also extremely shocked in his heart, but he had made a million meritorious deeds in four months, and it was more than one million in exchange for Xuanjing, which was a huge amount.

Lin Xiao glanced at the exchange catalog, and was very shocked in his heart, there were a lot of extremely precious resources on it, all kinds of spiritual materials of the fifth or sixth level, including minerals, elixirs, etc., as well as magic weapons, spirit runes, pills, and even the precious resources of Lingming Dan, of course, the price of Lingming Dan was extremely expensive, requiring 10 million merits, which was twice as expensive as Lin Xiao got before.

In addition, there are all kinds of flying boats and treasure ships, but for all the forces that want to survive in the Luoxinghai Islands, flying boats and treasure ships are necessities, the price of treasure ships is extremely expensive, a fourth-order high-grade treasure ship, an empty shelf will cost two million merits, if you match the Xuanjing Cannon and the God Exterminating Crossbow, you have to double the price.

In addition, there are also battleships, fifth-order battleships, which require 18 million merit points, not counting weapons, this kind of look is prepared for big forces, not an individual monk like Lin Xiao.

"The war is not over yet, so I won't change it for the time being, by the way, how many people came back from Dajin Island before, and how is the war now?"

"Of the six treasure ships on Dajin Island, four came back, with heavy losses, one Lingguang monk was killed in battle, five Daogang monks were killed in battle, more than one hundred and twenty Purple Mansions, more than 6,000 people in the condensing veins and veins, and more than 500 people were seriously injured and died after returning to Treasure Island, and less than 20,000 people really survived.

As for the war, it is still in the midst of anxiety, Treasure Island is the third line of defense of the Luoxinghai Islands, and it will not be easy for the demon beasts to surround the island, and now Treasure Island and the alliance have concentrated thirty treasure ships on the sea, one of which costs more than 40 million Xuanjing, and the grade has reached the sixth order, and it is fighting in the waters outside Treasure Island. ”

"Sixth-Order Treasure Ship, how big is that?"

"That's big, more than a thousand meters long, six hundred meters wide, divided into four decks, each deck can be set up on one side of three hundred Xuanjing cannons, but this thing can't afford to fight, if you really fire with all your strength, you have to hit tens of millions of Xuanjing in an hour, mainly enough to move the island, for the monks to rest."

The steward explained that the main treasure ships of the Luo Xinghai Islands are basically at the fourth-order level, and the fifth-order are few, not that they can't afford to build, but they can't afford to use them, and the cost of the sixth-order treasure ships is less than 50 million Xuanjing, but 50 million Xuanjing can be used up in a day when they are used for combat, and no matter how rich the Luoxinghai Islands Alliance is, they can't afford this cost.

"Understood, Xiao still wants to continue the campaign, if there is a suitable position, you can notify Xiao when the time comes"

"This is natural, the beast tide is not over so soon, it is expected that it will take at least half a year, some of them will fight, and I will inform Xiao Daoyou when there is news."

"Thank you very much, then"

Lin Xiao nodded, this beast tide is enough to make the Luo Xinghai Islands break their muscles and bones, and now they have been fighting for more than three years, and they have spent at least a billion Xuanjing, if they fight for another three years, the entire Luo Xinghai Islands will go bankrupt.

As for the loss of personnel, it was even more, Lin Xiao knew that more than 200,000 monks had died in the battle, almost as many as the monks in the entire Lu Kingdom, more than thirty Daogang monks, and two or three Lingguang monks.

Lin Xiao took a stroll around Chijin City, the reason why Chijin City has this name is because there is a red gold mine on the island nearby, red gold is a relatively precious spiritual material, at least it is the third order, and the best quality can reach the fifth order, and it has a wide range of uses in refining weapons and formations.

Originally, the red gold in Chijin City was relatively cheap, at least about 30% cheaper than Zhongzhou and Nanzhou, but now that the war is going on, the price has skyrocketed, and it is all used for war preparation.

Of course, because of the small production in the place of origin, it is estimated that Zhongzhou and Nanzhou will be more expensive, Lin Xiaocai bought a lot of raw materials for talismans, and is ready to raise the level of talismans to the fourth order, spirit runes are consumable supplies, especially in war, there are really as many as there are, how can there be more than demand, it is very easy to sell, and the sales volume far exceeds the formation, and even the pill cannot be compared.

And the spirit runes are really good in war, the wealthy monks throw out a large number of spirit runes, and the piles can pile people to death, while the poor monks have to fight with their own knives, and in the end it is self-evident who can survive.

It took Lin Xiao two months to raise his level to the third-order upper grade through a large number of spirit runes, and he already had a good success rate.

At this time, the defensive battle of Treasure Island has also moved to the periphery, the outer islands and reef strongholds have fallen one after another, and the thirty treasure ships have not been able to stop the demon beast army, and they will soon have to defend the island, and the alliance has also arranged a new task for Lin Xiao.

Because Treasure Island is already the third line of defense that cannot be lost, the alliance has hoarded heavy troops for this purpose, and in the case of troops, it is necessary to fortify everywhere, and set up war fortresses along thousands of miles around Chijin City, so it also needs the cooperation of array mages, refiners, and builders among the hundred craftsmen.

This task is safe and easy, but it is very testing for the level of the formation mage, and Lin Xiao also gladly accepted it, so Lin Xiao took a group of formation mages and went to various places to build war fortresses in accordance with the instructions of the alliance.

········

"This is the closest third-order high-grade spiritual vein to Chijin City, according to the meaning of the alliance, it should be set up as a fourth-order mountain protection array, Xiao Daoyou, is it feasible?"

"Yes, I will arrange a large array of spirit gathering, collect all the Xuan Qi, now that the spiritual field has been harvested, as long as I don't plant anything anymore, it can completely support the usual needs of the fourth-order formation, the big battle starts, and then use the Xuan Jing to make up for it."

"That's fine, but after the war, this family is quite related, and I hope we can settle it once and for all"

"The war fortress is different from ordinary means of protection, if the spiritual veins here are not improved after the war, then you can only reduce the formation level, so let's do it, when the time comes, I will write down all the arrangements of the formation, as long as they remove a few key positions, the formation level can be reduced, don't throw away the removed components, and when the spiritual vein level rises, it can be used again, which can save hundreds of thousands of Xuanjing"

"So the best, wouldn't it be too much trouble"

"No, it's the refiner Wen Daoyou who is in trouble, and he has to come to refine the formation components."

"Then it was decided"

"Okay, I'll go survey the terrain, and I'll come up with the formation map at night."

Lin Xiao nodded, and personally led a group of array mages to survey and map the terrain, mainly the distribution trend of the spirit veins, and to use the distribution trend of the spirit veins to design the formation.

In one day, Lin Xiao made the formation diagram, and the builder began to draw the fortress design map according to Lin Xiao's formation diagram, where to leave the Xuanjing cannon, where to leave people to guard, are all particular, and the refiner began to refine the formation components according to the formation diagram, and after refining, Lin Xiao will carve the formation pattern on it.

Two days later, Lin Xiao received the kindness of the family here, a total of 30,000 Xuanjing, because Lin Xiao could not have to be so troublesome, this was to help them save money, otherwise they would have to reset the mountain protection array after the war, which would be a huge expense.

The rest of the time, Lin Xiao went to the place where the second fortress was located to draw the formation map, and when the drawing was completed, he rewound back to carve the formation pattern, and then laid down the formation.

Together with the formation, the construction of the fortress was also rushed at the same time, day and night, because at this time, the demon beasts had begun to surround the island, and the fleet had basically shrunk to the vicinity of the port.

Lin Xiao continued to rush to the third fortress, and after drawing, he reverted back to carve the formation pattern of the second fortress, and so on and on, and after a month and a half, the formations of the twelve war fortresses had been arranged, of which six of the war fortresses had been completely built, and the remaining six were under intense construction.

At this time, the remaining fleet had completely withdrawn from the city, and the sea was already full of demon beasts, and thirty treasure ships blocked demon beasts for half a year at the cost of more than 10,000 monks on seven treasure ships, killing more than 200,000 water tribe demon beasts.

However, this number is not to the point of breaking the muscles and bones, because the fertility of some aquatic demon beasts is too terrifying, some fish can give birth to hundreds of thousands of fish eggs at a time, and it only takes two or three years to become a first- or second-order demon beast when there is enough food.

Although the growth potential of this demon beast stops, the food brought by their huge number can't even be supplied by the demon beast, so it needs to be constantly consumed.
