The difficulty in cutting off the supply line of the Elven Expeditionary Force is that there are too many people sent, and the huge number of scouts of the Elven Expeditionary Force cannot be concealed, and the number of people sent is less, and the elven warriors on the supply line cannot be defeated.

It is true that this task can be accomplished by sending a small number of elite masters, but the key is that cutting off the supply line and temporarily mid-to-upper supply lines are two completely different concepts.

In extreme cases, the Night Elves have the ability to use their abilities to generate food, and they can suppress the lack of supplies once or twice as long as they find an oasis and sacrifice their subsequent combat power.

Therefore, temporarily suspending one or two supply lines will not have much effect, and may even allow the Elven Expeditionary Force to launch a general attack in advance. This is contrary to Lin Xiao's purpose.

The key is how to completely strangle the supply line. In that case, the Elven Expeditionary Force would have only two options, storm and retreat.

In the case of a strong attack, the Arsa side can completely exchange space for time, let the elven expeditionary force enter the inner ring, and then drag it out for enough time. The Elven Expeditionary Force ran out of supplies and won without a fight.

As for retreating, it would be even better, just let the war end.

So the key is whether you can completely strangle the supply line of the Elven Expeditionary Force.

Although Tang Dou has done a lot of things because of Avalon, and even deterred many forces in the entire inner ring, there is one thing that outsiders don't know, and even Tang Dou just knew, that is, Avalon's teleportation convenience is limited.

The limitation is the distance it can teleport, which is about the same size as Avalon's entire space is now.

The current Avalon is almost a thousand kilometers in all directions, starting from the central lake.

The same is true for Avalon's teleportation range, which is centered on the last location where Tang Dou entered Avalon, and then extends about a thousand kilometers in any direction.

Beyond this distance, even beacons cannot be transmitted.

In fact, Avalon's teleportation is supposed to be a kind of coordinate overlay.

Avalon is fused into Tang Dou's soul, so in essence, Avalon is a part of Tang Dou's soul, and Tang Dou goes to any place in Avalon, in fact, he is looking for a coordinate point in his soul to move over.

It's as simple as figuring out a certain position in one's body through imagination.

And the teleportation between Avalon and reality is a kind of coordinate overlay, on an unknown level, with Tang Dou as the center, Avalon's map is covered in the surrounding space, and then Tang Dou opens the portal somewhere, so there is a teleportation.

To put it bluntly, this is a tricky approach, and without Avalon's help, Tang Dou would not be able to do such a thing as spatial teleportation.

This is also something that Tang Dou only figured out after studying it for a long time.

The Arsa Desert is a desert area that occupies a quarter of the Tianfeng Continent, and the straight-line distance from its outer ring to the edge of the inner ring is more than 2,000 kilometers.

And the Elven Expeditionary Force can compress this time to about twenty days, which is already quite fast.

More than 400,000 troops can occupy more than ten miles of territory, and Narius deliberately scattered the troops very much, so that the area monitored by the entire army is very large, plus the scouts, it can really be achieved to the point where any movement within a thousand miles can be discovered.

Therefore, even if Tang Dou came directly to the log oasis and extended the distance of Avalon's teleportation, it would be at most on the edge of the Elven Expeditionary Force, and once he started fighting with the escort troops on the supply line, it would soon be discovered by the main force of the Expeditionary Force, and then the gains would outweigh the losses.

What's more, Tang Dou is now completely in charge, and he doesn't know what to do.

Without the convenience of spatial teleportation, it seemed impossible to strangle the supply lines of the Elven Expeditionary Force.

But in such a situation, Lin Xiao thought that he had a not very mature idea.

Ellie looked at the oasis in front of her, which was being disfigured beyond recognition by the sandworms, and turned her face in distress: "No one can think of this solution." This is digging the foundations of Arsa. Elves are never to think of it! ”

Youyou was deeply impressed: "It's because they can't think of it, so they can't prevent it!" Miss Xiao's trick is really a clever plan! ”

Lin Xiao touched the back of his head and said, "Where, because Avalon is here, so I can think of this way!" ”

Speaking of this, her face fell: "I just didn't expect that the Elven Expeditionary Force would do such a great job this time!" ”

A trace of anger flashed in Ellie's eyes: "This group of invaders, under the slogan of justice, is doing the bloodiest massacre!" ”

Yu Yu sighed: "When any army starts an invasion war, there is no so-called justice. War has nothing to do with justice in the first place! ”

Lin Xiao's not-so-mature plan was actually very simple and sensational.

Destroy the oasis.

Unless there is someone like Tang Dou who carries another space with him, he has to rely on the oasis to move in Arsari. This is especially true the further you go to the inner ring, where you can see some small strongholds a little far from the water source, but after the middle ring, it is absolutely impossible to see a long-term stronghold outside the oasis.

Without the shelter of the oasis, no one can be exposed to the wilderness of the Arsa desert for a long time.

Sandstorms, monsters, and scorching suns are all mixed together, which can make a platinum powerhouse fall into it and die. An army is inseparable from the guidance and protection of the oasis.

The oases in the outer ring of Arsa are often not fixed, and it is possible to change a batch every ten or twenty years, no one knows how this works, but it has been the case for thousands of years. From time to time, oases die out, and from time to time new oases are created.

But from Central onwards, there are more and more constant oases, and they are becoming more and more important.

And these constant oases have guide stones, and through the resonance of the guide stones, people in the desert can not get lost. And these constant oases form a zigzag lifeline.

Lin Xiao's plan is very simple, to pull out these lifelines in Central.

Even if the Elven Expeditionary Force raised its butcher's knife at the passing oasis, it did not think of destroying the oasis. Arsa has been in turmoil for thousands of years, and there have been countless changes of power, and no one has ever thought of destroying the oasis.

Because the oasis is everything about Arsa, the foundation, the foundation, without the oasis, Arsa becomes a real forbidden area for life.

What if you completely destroy a constant oasis in a certain area of Central?

Simplely, until the positioning method is refound, the inner and outer layers will be completely disconnected. Don't let the people out want to come in again, and don't want to go out again.

The sensing range of the Guide Stone is limited, unless you are lucky enough to rush directly into the unguided area, and then rush into the sensing range of the Guide Stone before you are finished.

But those who can do this are undoubtedly masters who are at least gold level 5 or above. There are not many such people everywhere.

Unlike a short-lived oasis, a constant oasis cannot be regenerated once it is destroyed. There is an area in Central that is quite famous as a forbidden area, the reason is that the two territories fought too hard, and as a result, both of them completely destroyed each other's oases, so that large area has not generated new oases for a thousand years.

So for a thousand years, that large area of forbidden areas has become the best warning sign.

Don't move the oasis.

No one dared to fight the idea of these constant oases.

The fundamental reason why Tang Dou could use his spatial teleportation and rune puppet to deter all the big and small forces in the inner ring was that he had the ability to destroy the major constant oases at any time, and no one wanted to die with this madman.

But Lin Xiao is now working on this foundation. Do it in a place where no one thinks about it, doesn't dare to think about it.

And Lin Xiao's confidence is Avalon, a place as big as Avalon, it is no problem to fit everyone in the entire Arsa!

And this confidence also exposed Lin Xiao's ambition to grow up under Tang Dou's long-term influence.

The Half-Elf Girl has already figured out how to pack the people of Arsa into Avalon as much as possible.

When Lin Xiao said this idea, Ellie and Yuyou were taken aback, and they knew very well what the bad consequences would be if they destroyed the oasis at the key node.

But after they listened to all of Lin Xiao's arrangements, they calmed down.

With Avalon here, Tang Dou's side has enough confidence.

Backed by a new and vibrant world, what kind of confidence do you want?

In order to ensure that the operation would not be discovered by the Elven Expeditionary Force at first, Lin Xiao and the third daughter brought Elucie over alone. Four girls began this operation "behind enemy lines".

First, he used the space to teleport to a place less than thirty miles away from the main army of the Elven Expeditionary Force, and then used Lin Xiao's large pile of equipment armed to the fingernail cover to deceive the reconnaissance of the expeditionary force scouts, and then hurried all the way, and it took half a day to rush to several key nodes jointly selected by Ellie and Youyou.

It was the point where Ellie and Yun had the least impact on Arsa after careful consideration, but it was the most likely to interrupt the expeditionary force's supply lines.

There were four oases in total, and once these four oases were destroyed, the supply line of the expeditionary force would have to be interrupted unless it could be extended for another thousand kilometers.

And did not completely strangle all the nodes in this area, in order to leave a way back.

Nothing can be done.

Originally, the four girls thought that when they came to these four oases, they would still have to face a group of poor Arsa, and they didn't know how many people would look for them desperately while watching them destroy the foundation of their existence.

This point really gave Lin Xiao and several other girls a headache, and in the end, they could only comfort themselves by taking one step at a time. When they came to the first oasis, they saw a no-man's land.

There are no people in the oasis that should be lively, and there is no popularity at all. In the end, it was Po and Koharuko who discovered the clue with their keen sense of smell and saw the Arsa people being slaughtered in a concentrated manner outside the oasis.

In order to completely cut off any interference, the Elven Expeditionary Force directly killed all the people who passed by the oasis.

The slaughtered Arsa people have basically been gnawed by the monsters, leaving only a large number of bones, proving that there was another massacre here.

It is precisely because of this massacre that Ellie and Youyou, who have always hesitated, have completely made up their minds.

We must stop the Elven Expeditionary Force this time, and we must not let these guys pass through the log oasis, otherwise more people will die.

Eighty percent of the population of the entire Arsa is concentrated in the inner ring, and the transportation in all directions of the inner ring also makes it destined that once the elven expeditionary force passes through the log oasis, it can rely on the numerical advantage to launch multiple waves of attacks.

At that time, even if the people in the inner ring fight back with all their might under the leadership of Tang Dou, even if they have the convenience of the teleportation array, they will be exhausted, and how many people will survive at that time, who knows?

So soon under the summoning of Elusie's dragon power, several sanddiggers were summoned, and after Lin Xiao blew up the water source of the oasis with a large amount of explosives, the rest was handed over to the sanddiggers.

Sand digging insects instinctively hate places with water, so they will not take the initiative to approach the oasis under normal circumstances, but under the orders of Elusie, a dragon clan, they can only resist their instinct to attack, plus the water source was destroyed by Lin Xiao first, and the action of the sand digging insects will not be greatly affected.

Thus, in less than an hour, a vibrant oasis was completely destroyed.

Ellie took out the guide stone and tried it, and sure enough, there was no sense.

The Guide Stone is a rather strange rune stone, and the Resonance Stone that stands in the oasis is actually just a magnifying device that allows the Guide Stone to feel the location of the oasis more clearly, but the Guide Stone itself actually senses the oasis itself, not the Resonance Stone.

This is also why the Seven Kingdoms of the Inner Ring do not need the Resonance Stone, because the oasis is large enough that the Guide Stone can be sensed far away.

And when the oasis is destroyed, the guide stone loses its senses.

Glancing at the original site of the oasis that had been turned into a wasteland, Ellie gritted her teeth: "Next place!" ”

Five hours later, in a hurry with the four girls, they finally came to the last critical node, which was also the biggest one.

The node itself acts as a traffic mouthpiece similar to a log oasis, from which you can reach many places in Central, including Ellie's former home.

The name of this oasis is Getil, which means "mouthpiece" in the native language of Arsa.

Gatil is an extremely important oasis in Central, so it is not controlled by any force itself, and every elven expedition must pass through Gatil, and no Central force can't think of running a place that will be robbed every fifty years.

So Gettier is an unmanaged oasis, or a place where the forces of Central are jointly managed. No one is going to make a big fuss here, but it's not a peaceful place itself.

And now, Gattier has been set up as a transit barracks by the Elven Expeditionary Force's Logistics Baggage Legion.
