The lack of intelligence made it impossible to judge the true movements of the Demon King Army, which made Lin Yuedong and Li Qinglan unable to make a judgment for a while, and the Holy Maiden and the others were also uncertain, so the coalition army had to continue to stumble in Ostachia.

The true purpose of the Demon King Army is not easy to judge, but there is always a way to knock on the side. From the afternoon of the day of the meeting, there was an endless stream of scouts heading eastward, looking at the absence of the Demon King's army, swaggering around to collect information. The locals were so miserable by the Demon King's brutal decree that when they heard that the coalition was coming, it was as if they had met their relatives, and soon a large amount of information was sent back.

At present, most of the places that Tanma can reach are occupied by the Demon King Army later, in addition to complaining about how the Demon King Army kills innocents indiscriminately, it is to mention a policy change in the Demon King Army.

Most of these places were occupied from a year ago to half a year ago, and after the occupation, the Demon King Army also asked the locals a lot of news about the distribution of minerals, plants and animals, and organized the people to open mines and reclaim the wasteland, as if they wanted to maintain peace and stability for a long time. But since about a month ago, the Demon King's army has fully shrunk to various cities, and then there is no action, leaving those hard-mined mines and fields there.

Calculating the time, a month ago happened to be the day when Lin Yuedong and Li Qinglan arrived in this world. At that time, the Demon King's army should be planning an attack on Lauren Frost, and Amos's team had just hit the road.

"What's the connection?" Lin Yuedong was a little suspicious. The Demon King's army sent 5,000 men and horses to the north, and the front line was empty, so they all stepped up their defenses from the east of Celal and contracted their defenses, which can barely be said to be a reason. It's just that Barnaby and the others are not so cautious and don't seem to be able to do such a thing, not to mention that they had already reached a secret agreement with the Holy Lukia Kingdom at that time, and there was no need to be so vigilant.

"Barnaby is the commander of the Western Front of the Demon King Army, but not the commander of the entire Western Demon King Army, he can command the garrison of Salal, but for the army further east, he may not have the power to move." Li Qinglan's eyes flashed, and she analyzed the problem from the perspective of authority, "I think, I'm afraid it's not because of the strategy of the Demon King Army going north." It wasn't Barnaby who made the Demon King's army shrink. ”

"So that means that something else happened a month ago to stop the Demon King Army from building, or that they may have achieved their goal." Lin Yuedong rubbed his welcome**, "Didn't the Tanma report that something big happened a month ago?" ”

"Nope. But I think I might have some clue about it. Li Qinglan said thoughtfully.

"What do you think?" Lin Yuedong hurriedly asked.

"A month ago was not only the day when the Demon King's army planned to go north, but also the day when you and me, as well as the two rabbit cubs of the demon clan, came to this world." Li Qinglan said.

Lin Yuedong pinched his fingers and counted, no, it was only a month since the two of them arrived at Lauren Frost.

But even if this is the case, how can it cause changes in the Demon King Army? Could it be that Seven and the Blood Knife went to the Demon King Solomon immediately after their arrival and told him something to make him do this?

It shouldn't be that simple, right...... The demon king Solomon lived in a simple place, even if he wanted to see it, it would be troublesome, not to mention that he was allowed to do such a thing that affected half the country in just a few days. Unless, what killer weapon does the demon king have in the hands of those two people of the demon clan?

"No, it shouldn't be what the people of the demon race did, but our arrival in this world itself has become an opportunity for Solomon to shrink." Li Qinglan thought about it and said.

"How?" Lin Yuedong asked.

"When we were in the North Pole, we also saw it, a magic circle that summoned Zanita from the elven realm, but it simply summoned the darkness of the other world, at that time you and I only thought that the connection between the other world and this world was too close, but now I think about it, it is not the case. If such a simple summoning array can summon the darkness of the other world, there are so many elves in the human world now, I am afraid that there will be hundreds of summons to the elves every day, wouldn't the darkness of the other world have long been all over the world? Li Qinglan asked rhetorically.

Lin Yuedong suddenly realized. Yes, at that time, Luciini arranged the magic circle used by their clan to summon Zanita from the elemental elf realm, not a magic circle that specifically summoned the darkness of the other world, so that it could attract the darkness of the other world, could this kind of summoning be so simple that every magic circle that summoned elves from the elemental elf realm could summon the darkness of the other world?

The answer is clearly no. Until a thousand years later, the darkness of the other world is still limited to the five great elf kings, and it has not been poisoned in the world, indicating that the darkness of the other world is not as easy to summon as imagined. Lucien's success was probably not because the darkness of the other world was easy to summon, but because the conditions they used to summon at that time were very complete.

That summoning, the magic circle is a normal magic circle, and the person who controls the magic circle is nothing special, if you want to say it, it is not completely the divine power flowing in the leylines that is used to urge the magic circle, but mixed with the divine power of the ice god......

Thinking of this, Lin Yuedong's eyes widened: "Could it be that the darkness of the other world is actually related to divine power?" ”

Li Qinglan bowed his head and said: "I'm afraid it's indispensable, but what the relationship is, we have to think about it carefully." It's just that if this is the case, then a month ago, the wooden pen sent you and me into this world, which is equivalent to playing for the tiger. ”

Lin Yuedong still didn't understand: "Why is that?" ”

Li Qinglan said eloquently: "It's very simple. The principle of sending the courier to the otherworldly passage to other worlds is to use divine power to penetrate a hole in the crystal wall outside the world, and after sending people in, the divine power is withdrawn, and the crystal wall is naturally bridged. But in this process, there is an extra hole in the crystal wall out of thin air, and the defense against other worlds is naturally weak, perhaps the world where the darkness of the other world is located sees this opportunity, and uses the power of the otherworld channel to pass through the crystal wall and make contact with this side. ”

Lin Yuedong only listened dizzy: "Senior, I don't understand what you said." What crystal wall? Is it the crystal wall in the Dungeons & Dragons rules? ”

"Almost." Li Qinglan thought for a while, and out of nowhere, she found a crystal ball, and several balls of light slowly circled inside, "Let's borrow the real thing, it's easier to explain." When it comes to space-time channels and the like, we have to mention crystal walls, and when we talk about crystal walls, we must explain the crystal wall system. This is a model of the crystal wall system, which I got by chance before, and it is the most convenient to explain. ”

"Crystal wall model?" Lin Yuedong stared at the crystal ball with great interest, knowing that this was a great opportunity to learn the secrets of the world's structure, "Seniors, please speak, juniors listen." ”
