"The world you and I live in is generally called the main material plane." Li Qinglan pointed to a large ball of light in the center of the crystal ball and said, "Look at this ball of light, it represents the meaning of the main material plane. Generally speaking, a primary plane of matter is a universe that you see. Of course, this is not absolute, as far as I know, there are only three or four planets of the main material plane, so it is very poor, let's just talk about the normal situation. ”

Lin Yuedong looked carefully, there were all kinds of images in that big ball of light, human houses, plants, trees, beasts, etc., it was hard to believe that such a small ball of light could show so many images.

He had heard of the term "main material plane", which, like the crystal wall, came from the setting of DND, which probably referred to the world inhabited by humans. It's just that the description of the main matter plane in DND is quite broad, and the default world of most DND stories belongs to the main matter plane, such as Klein, Torrell, and so on.

"At the same level as the main material plane is the inner plane, usually the six element planes of fire, water, air, earth, light, and darkness, of course, this is not absolute, there are seven element planes, there are also five element planes, yin and yang planes, and so on. The inner plane is the basis that forms the main plane of matter, and a plane of primary matter must be made up of the surrounding inner plane. The inner plane can exist independently of the main material plane. Li Qinglan pointed to a few smaller balls of light around the light balls of the main matter plane, and then introduced.

There wasn't much in these orbs of light, just clumps of fire, water, dirt, and so on, showing the differences between the inner planes.

The inner plane also comes from the DND setting, but Li Qinglan's narrative is quite different from the original DND version. The inner plane in the original version refers to the six-element plane, and there are no other types, nor does it say that the inner plane is the basis for building the main material plane, so it is probably the maverick of those worlds.

If the main plane of matter is an edifice, then the inner plane is a mass of bricks, cement, paint, ...... It is also easy to understand that the surrounding bungalows are piled up with materials used to build houses.

"There are subordinate planes below the main material plane, and these planes depend on the main material plane for their existence, and if the main material plane is gone, these planes will disappear as well. For example, the etheric plane, the shadow plane, the dream space, and so on. Li Qinglan pointed to the smaller balls of light.

The scenes in these balls of light are even more blurry, some are dim and difficult to discern, some are pitch black, and some are even more bizarre and incomprehensible.

"There is a half-plane down again, which is actually called a plane or not, mainly referring to some small spaces that exist in the main material plane, so let's not mention it for the time being." Li Qinglan said, "A main material plane, an unequal number of inner planes and lower planes, and more half-planes, add up to a complete crystal wall system, which can also be called a complete world. ”

"So, the crystal wall is the outermost layer of the crystal ball, right?" Lin Yuedong immediately asked.

"Exactly. Outside of a crystal wall system, there must be a crystal wall that encompasses the world and makes it an independent whole. There is a saying that 'even if I am locked up in a husk, I still think I am the king of infinite space', and in fact, we are still in such a husk. Li Qinglan said eloquently.

It doesn't seem to be too much different from DND's crystal wall setting......

Lin Yuedong thought for a while and said, "Jingbi, I understand. So what's going on with the space-time channel? ”

"Speaking of which, the space-time portal is quite a brutal tactic." Li Qinglan smiled, "In fact, it is to use divine power to cut a hole in each of the shells of the two crystal wall systems, and throw the things of one world to the other world through these two holes, and you and I are shuttling between the worlds again and again through this means." The crystal wall has a certain self-healing power, and even if it is broken by an external force, it will still heal on its own, so it is not a problem to open it a few times. ”

"If you drive too much, there will be a problem?" Lin Yuedong asked keenly.

"Yes. Otherwise, why do you think there are only two of us? Wouldn't it be better to send a few more people? Li Qinglan smiled, "It's because the more people there are, the greater the damage to the crystal wall, once the damage reaches a certain level, the crystal wall will collapse on its own, and people from other crystal wall systems can come and go on their own, and many planes will also lose their constraints, and then this world will be finished." ”

Lin Yuedong then understood. He had always thought that the gods were unwilling to send more couriers in one world because of the lack of people under them, but now it seems that they are actually afraid that one world will not be able to support them to send more people, so they can only send one or two.

"Like this world, it's barely the kind of people who send four people in, two demons, two of us, and there are no more. And these four people enter the crystal wall, and the crystal wall is pierced with two holes, and it is temporarily unstable, and it is easy for something to take the opportunity to mix. Li Qinglan said.

"That's ...... No, the human realm and the elemental spirit realm are so closely connected, the crystal wall of this world should have collapsed a long time ago, right? Lin Yuedong asked.

"You are confused by the title. Although the people here call it two worlds, it doesn't mean that they necessarily belong to the two crystal wall systems. Li Qinglan blinked, "The human realm and the elemental spirit realm both belong to the same crystal wall system, and it should be the relationship between the main material plane and the lower plane, and it is not a problem to interact with each other. But that otherworldly darkness is afraid that it comes from other crystal wall systems. ”

"In this case, it is indeed reasonable......" Lin Yuedong thought about it again and again, and felt that it was indeed possible. Solomon was intent on attracting the Darkness of the Atlas from another Crystal Wall System, and a month ago there was turmoil in the Crystal Wall of this world, so he took this opportunity to achieve some phased results, and may even have attracted the Darkness of the Otherworld. After the goal was achieved, he began to order the Demon King's army to shrink and do his own thing—the logic was smooth.

When he thought of this, he was shocked: "So, Solomon is likely to have achieved his goal?" ”

Li Qinglan also thought of this section, and her face was serious: "The Demon King Army stopped caring about those mines and anything a month ago, but I am afraid that Solomon will really get the opportunity to do something." Perhaps, he is summoning the Darkness of the Otherworld. ”

"Thinking about it this way, now he orders all the troops to retreat to Zohar, maybe it will be a trap - after luring all the coalition forces over, he throws out the Otherworldly Darkness, and the coalition forces will be wiped out on the spot!" Lin Yuedong pointed out.

"Do you want to follow our example and trick the Demon King Army into the Kilia Mountains?" Li Qinglan thought for a while, "It makes sense, I have to guard against it." In this case, it is better to move slowly. As long as you can spread the power all the way through and turn all the occupied areas into the rear, you can be prepared when you finally face the darkness of the other world, and you will not be defeated for thousands of miles. ”

"Then let's do it!" Lin Yuedong slapped the table and went to find the Holy Maiden and the Duke of Elstein.
