The biggest difference between the Arsa Wilderness and the Haisha Desert that Tang Dou has been to is that the latter is a pure desert environment, and in it, you need to consider that you are also facing a desert environment. But the former is very different, the Alsa Desert and the Alsa Gobi are intertwined, and the boundaries between the two are blurred and constantly changing under the influence of sand and storms.

People who live in the wilderness of Arsa want to travel long distances, and it is absolutely impossible to find the right way just by looking at the sun, moon, stars and maps, because the terrain here changes at any time, and even the sun, moon and stars in the sky are not as simple as they seem.

The cause of the Arsa Wilderness is the battle of the elves in the battle for the dragon, and the surrounding environment was severely damaged by the powerful battle, just like the strange environment in the interior of the Fog Hidden Continent, the Arsa Wilderness has one of the most famous and deadliest weather, called "Broken Sky".

Most of the time, the sky of the Arsa wilderness does not see the full sun, moon and stars, and when you look up, you can only see the reflection of the sky like broken glass. When the weather in the shattered sky appears, only the shadow of the sky can be seen.

You will see dozens of suns, dozens of moons, and a sky full of completely irregular stars swirling in the sky, as if you are going crazy, not to mention using them to identify the direction, even if you look at them for a while, you will feel dizzy.

Therefore, for long-distance operations in the Arsa wilderness, what is needed is a rune stone called "positioning rune", which is located in an oasis, and in each oasis that can exist for more than ten years, a positioning rune stone called "mother stone" will be placed, and then those who hold the "sub-stone" positioning rune can locate the position of the mother stone closest to themselves.

This reminded Tang Dou of an anime he had watched in his previous life.

He was quite interested in this kind of positioning runestone, and borrowed Ellie's to use it, but it was very oolong that after he fiddled with it for a while, the point of this thing changed to point at him all the time. Fortunately, positioning runes is not a valuable thing, and Morian and Eugene have both them, which saves Tang Dou from embarrassment.

However, taking this as an opportunity, Tang Dou broke the difficulty of the communication rune stone that had not been studied before.

There are communication runes in the Thousand Souls Spirit Realm, and in addition to the most primitive models that pinch a broken two in an emergency, there are also several high-grade ones. But the highest level is to write the text on special paper and then burn it with the fire of the runes in the communication runes. In this way, on another pair of communication runes, the corresponding text will be formed with rune fire.

In Tang Dou's opinion, this kind of communication method that is text messaging is already the most advanced communication method in the Thousand Souls Spirit Realm, there is no limit to distance, but the number of words is limited, it cannot exceed fifty words each time, and there is a limit to its use, and the best one can only be used a hundred times.

Moreover, this kind of communication rune stone is quite difficult to make, and the cost is extremely high, and it is often owned by the generals who lead the army to fight outside, which is used to report emergency military information.

Tang Dou got a pair from Zhengde and has been researching, and later he also got several low-level from Impatiens Flower Ji, but after researching and researching, he has never been able to get the phone effect he wants. But this time, on the positioning rune stone, he found a breakthrough in inspiration.

In fact, the runes in the Thousand Souls Spirit Realm are very richly developed, there are runes that can form images, runes that can make sounds, and runes that can communicate with each other. This gave Tang Douxiang the basis for making a phone call from another world, but he couldn't get a base station, so the communication rune stone he got before was completely a big speaker, and all the rune stones would respond if he roared.

But on the locating rune stone, he found inspiration for the directional sending of signals.

He has been studying the communication rune stone for more than a year, and now his inspiration has exploded, and he has come up with several verified models in two days.

"Hey, Mistress Nicholas, can you hear me?" Ellie's voice came from the palm-sized rune stone in Tang Dou's hand, and her voice was somewhat distorted, but she could still vaguely hear the voice of the butterfly girl, as well as the surprise, curiosity, and joy.

"I heard it, it was very clear, but the sound was a little deformed, and I guess I had to adjust it. Where are you and Xiao Ya now? Tang Dou smiled slightly and replied with a communication rune stone.

"Ah, I really heard that!" The butterfly girl's exclamation came, and then she stabilized her emotions: "Miss Xiao and I have already arrived a hundred miles away!" ”

"Alright, let's come back first! I'm going to do the next set of tests~! Tang Dou ended the call, and then changed the runes on the rune stone in his hand a little bit, which was also his proud work, through the combination of different rune signals like a Rubik's Cube, and finally the ability to call different communication runes.

After changing the number, a babbling voice immediately sounded in the rune stone: "Hahaha, dear, dear, did you hear my voice?" I see the rune stone light up, do you hear me? ”

"I heard it, I heard it, where did you go?" Tang Dou heard a strange voice from Chihuo's side, and asked puzzledly.

"Ah, I'm in a fight and I caught a big bug, so big! Po suppressed it, and I was about to get it back! Ah, wait a minute, it'll be fine soon! Chihuo said and hung up.

Tang Dou was in a cold sweat, this girl really didn't have a quiet time, with her strength, did she need Ah Bao to suppress the demon beast? What kind of strength is this? What the hell is this girl doing?

Looking up at the direction where the Red Fire Project went, I didn't know if it was a psychological effect, there was a faint amount of sand and dust rolling up over there.

"Is Fire Sister alright? After all, this is not the time for her to show her strength, and if she gets excited, it's not good to use that trick indiscriminately! Sha Yunyue said with some worry.

"My lord, let me go and see!" Eugene offered to ask.

Eugene is Morrian's right and left hand, and Morion's adopted son. He has the Flying Eagle Battle Spirit, not only is he good at reconnaissance, but his War Spirit also fuses with him in an emergency, allowing him to have the ability to fly for a short time, and his gold-level strength can also ensure his survivability.

"Okay, you go and see, if there is danger, call immediately!" Tang Dou stuffed a communication rune stone into the other party.

Eugene nodded, and after fusing with his own battle spirit, he spread his wings behind him and flew up.

"This damn stupid girl, come back and clean her up!" Tang Dou's head was big for a while.

Morian smiled indifferently: "Listening to the second lady's voice just now, there should be no problem." And they're not too far away, so we're always ready to come to the rescue if needed! The old knight paused, and then looked at the communication rune stone in his hand with a sigh: "The talent of the adult, Morian admires it very much, I never thought that the communication rune stone can be used like this." A distance of 100 miles, just between this small rune stones, magical, magical! ”

Tang Dou slandered in his heart: "What's there to be happy about this earthy mobile phone that can only store seven phone numbers, but it's a pity, if it weren't for the damn son of prophecy, I might be rich in the world by running a communication company at this time!" ”

"Ahaha, it's a little thing, it's a little thing, and this thing is not perfect enough, I will continue to improve. I think Knight, Morien, is as wise as you are, and you should see the true use of this thing! However, what Tang Dou thought in his heart was different from what he said in his mouth.

Morian immediately became solemn: "Yes, the work of adults can be said to have brought about a revolutionary change. The tactical arrangement will be more treacherous because of the effect of this thousand milestone, and it will also facilitate our various actions. ”

Wartime communications are a rather important thing.

In the ancient times of Tang Dou's previous life, no matter how capable a general was, when he encountered a lower-level officer like a pig, he could only catch blind. Everyone knows that no matter how good the plan is before the war, when the real fight starts, what drums will be beaten, the troops will be withdrawn, what the orders will point to, and the troops will be headed. In most cases, these are not narratives, but adjectives.

Often in many cases, once the battlefield is too large, it is really each fighting its own battle. If you can follow the original plan, it is naturally best, and if you can't follow the original plan, you can only rely on the ability of the junior officers.

That's why there is a saying that a thousand troops are easy to get, but a general is hard to find.

The first general here is not a general, but those middle and lower-level officers.

But when it came to the modern war in the previous life, the situation was very different, instant messaging made a fundamental change in the battle, a hundred miles of battlefield in ancient times was considered a big one, but in modern history, every move is a thousand miles of attack, global combat. But at that time, it was rare to hear about the chaos of front-line generals.

Why? Because the communication goes up, even if the middle and lower level officers can only be a herald, then there is no problem, the staff will explain all kinds of operations in detail and thoroughly, and then the middle and lower officers will have no problem at all as long as their IQ is above the average - of course, it would be better if the middle and lower officers were geniuses.

The change in communication has changed the war with it.

The communication conditions of the Thousand Souls Spirit Realm are limited compared to the ancient strength of Tang Dou's previous life, so it is conceivable that when this kind of communication rune stone named by Tang Dou Thousand Miles Stone appears on the battlefield, how convenient it will be?

"When it comes to commanding operations, it's not going to work. I don't have a lot of people in my family. Maurian Knight and Miss Ellie are experts at this, and it's up to you to perform. That Kakas, just like our test subject! Tang Dou laughed.

Moritan was fiery for a while.

"My lord, I've found the second lady, uh, she's ......" Eugene's voice suddenly sounded in the Thousand Miles Stone, sounding a little tangled.

"What's that stupid girl doing again?" As soon as Tang Dou heard it, he knew that he was going to pit.

"The second lady and Ah Bao caught a sandworm, the adult kind!" Eugene couldn't laugh or cry for a while.

Sand digging insects, silver level 9, a specialty of the Arsa wilderness, its size is huge, it eats desert animals and monsters for a living, and can sleep for a long time when there is no food, it is said that there have been sand digging insects that have been dormant for a hundred years without dying.

The smallest adult body of the sand digger is 100 meters long and more than 20 meters thick, and its characteristic is to hide under the sand and open its huge mouth to form a seemingly calm quicksand area.

The combat power of the sandworm cannot be calculated normally, they are lazy by nature, not easy to move, the typical type of waiting for the rabbit, but if they are really going to be provoked, the seven or eight demon beasts of the idle gold level will not be their opponents, after all, the huge size and the characteristics of acting like the wind under the sand make it easy to be invincible at the beginning of the battle.

"This stupid girl is full, what are you doing to provoke sandworms?" There was a bruise on the top of Tang Dou's head.

"My lord, I have joined the second lady, she wants to ......" Before Eugene finished speaking, he was immediately interrupted by Chihuo's voice: "Haha, dear, I caught it, I caught it, but I and Ah Bao can't pull it, you come quickly." This guy is big, we can eat it for a long time, and its skin is very powerful, my nail palladium can't be pierced, didn't you say yesterday that you want to find some leather to make leather armor? It's just right! ”

Tang Dou's anger disappeared all at once. He now knew what Red Fire was doing when he recklessly ran to catch the diggers.

Although this stupid girl may not know it, the flesh of the sandworm is poisonous and cannot be eaten, and the skin cannot be made into leather armor - who has ever seen that the skin of a mollusk can be made into leather armor?

With a wry smile, Tang Dou sighed lightly: "You, let's come back first, forget it, I'll come and pick you up!" Just waiting there. He knew that Chihuo must still be in a state of excitement, and he probably wouldn't listen to her if he asked her to give up the worms she had worked so hard to fight and come back.

The main thing is that he is afraid that this girl with a bad temper will take her temper out on Eugene - Chihuo has always had a bad attitude towards people outside of his family.

"My lord, the second lady has made a big gain this time!" But Morian said in surprise after Tang Dou hung up the communication.

"Huh?" Tang Dou looked confused.

Morian excitedly explained, "Adults may not know that they don't live in Arsa, and the sandworm is also called a treasure worm by us. They do eat everything, but they don't digest everything. It has a huge internal sac that stores all the indigestible stuff inside. A lot of the time it's a big takeaway. Because from time to time, some caravans or robbers will be swallowed by sandworms. And it takes them two hundred years to reach adulthood, and what an adult sanddigger will swallow is more than most people can imagine! ”

"And sanddiggers can't digest metals, ores, and other things. And if we're lucky, that sandworm happens to be killed by the second lady in his lair, then we might be able to find the sand core, that's a good thing! ”

Who is Tang Dou? This guy is a big money fan, listening to Morion's words, his expression is visible to the naked eye. (To be continued.) )
