"Solved. The white wolf put down the pen and paper and breathed a long sigh of relief.

After four hours of hard fighting, he had finally succeeded in deciphering the six-pointed star rune array, and now this small dagger that shone with purple light and spewed gray mist from all sides had no secrets to him except for the sharp material that could cut through stones with a single sword.

In general, these six runes are divided into two categories, the first type is the coordinate rune, which is used to set the location of the portal, there are a total of three coordinate runes, which correspond to the three dimensions of space, and these three dimensions together determine a coordinate, and then the portal will be opened at the position of the coordinates.

The second type of runes is called maintenance runes, and they are used to maintain the teleportation channel, and the portal can only function stably if all three runes are opened and they are provided with sufficient energy.

The current situation is that two of the three maintenance runes are closed, so the energy provided by it cannot fully maintain the opening of the portal, which causes the portal to open and close for a while, and the purple light is constantly flickering.

The white wolf thought for a while, and entered the origin power into one of the closed maintenance runes, which was actually the original black power.

The maintenance rune was activated the moment it touched the black power, and the purple light on the rune array no longer flickered, but turned into a stable, intense purple light, and the speed at which the gray mist emerged was greatly accelerated.

At the same time, the white wolf also felt a suction, which was sucking itself into the teleportation array, but this suction was not particularly strong, and the white wolf could easily resist it.

The white wolf placed the dagger under his shadow, and then took out the shadow and put it under the sun for a while. The purple light emitted from the dagger would become faint as long as it was illuminated by the sun overhead.

This faintness was not a visual phenomenon caused by the intense rays of the sun, but was truly weakened, and the white wolf put the dagger under the sun back into his shadow, and found that the purple light had indeed faded, and there was no sign of recovery.

"No wonder the man the black wolf said was going to bury the dagger in the ground, so it was. The white wolf who witnessed this scene suddenly realized that this purple light is the light emitted by the teleportation array, and the sun's irradiation will make the purple light weak, and the essence of this phenomenon is that the effect of the teleportation array is inhibited by the sun, although the white wolf did not understand the principle of this inhibition, but he knew that placing the teleportation array away from the sun would definitely make it play a better role.

Another reason for placing the teleportation array underground is probably due to the suction, and the practice of placing the teleportation array underground is considered a safety procedure, which can effectively prevent the user from misoperating and getting too close to the teleportation array, and then being sucked in.

The white wolf dripped his blood on the two maintenance runes in the open state, those complex lines were submerged in an instant, and the original rune structure no longer existed, you can make such an analogy, if the original rune is a circuit, then what the white wolf did was to cover it with a conductor, so that the whole system was short-circuited, so that the maintenance rune no longer worked, the purple light no longer lit up, the gray mist no longer appeared, and this teleportation array was closed by the white wolf.

"Why did you turn off the teleportation array, why don't you go in and take a look?" the black wolf looked at the white wolf's actions suspiciously, not knowing what he was thinking.

"The valuable rune technology has arrived, it's time to stop it, God knows if there's something on the other side of the portal, I don't dare to go in anyway. The white wolf said smugly.

"I see, what did you learn from that pile of rune arrays?" the black wolf asked with interest.

"I have learned the black technology that surpasses the science and technology of this era, the space folding gate technology of the star spirit, if you don't understand it, you can also use it as a kind of rune magic circle, this magic circle can make people teleport from one place to another in an instant. The white wolf stroked the dagger in his hand and replied.

"Do you mean teleportation?Is there a limit to the distance of teleportation?How many people can be teleported at a time?Will there be security problems?" The black wolf asked suspiciously, as a warrior, she thought of military use the moment she heard the effect of the portal, if she could throw her troops to the enemy's base camp in an instant, then there would be no more strong fortresses, and there would be no army that could not be defeated.

"Theoretically, there is no distance limit for teleportation, a portal can only be used by one person at a time, and if enough energy can be provided to the circle, safety is not an issue. The white wolf conceived the language, trying to make his answers more precise

"Really, you didn't lie to me?" the black wolf looked incredulous.

"When did I lie to you? But I'm only talking about the theory that it can be done, and it will take some time to turn such a technology into reality. The white wolf replied.

"It's not that I don't believe you, it's just that what you said is too unbelievable, I haven't heard of such technology when I fought those human heroes in the past, but I've only seen someone use flashing. The black wolf flicked his tail in embarrassment.

"Actually, you've probably seen it, this teleportation array should be the same thing as the rune circle used by the guy with a misty face in your mouth who summons demons with an entire town as a sacrifice. The white wolf replied in a sure tone

"Really, if that's the case, if you want to apply it to reality, what's the difficulty?" The black wolf was a little puzzled, since the runes have been analyzed, can't they just be used?

In her impression, runes are such simple and fast things, the black wolf has lived in the territory of the white wolf for a long time, and has seen so many rune machines that can bring convenience to people's lives, she subconsciously thinks that it is very easy to make these machines. Perhaps the white wolf also played a certain role in the formation of her concept, because of the white wolf's unique talent, and his unique fineness that belongs to the programmer, the white wolf has always been drunk in one go, and there are very few cases where the rune needs to be modified by the wrong carving, which also makes the black wolf have a wrong impression of the matter of carving the rune, and she still thinks it is a very easy thing.

"Well, I'll explain to you how this rune works, and you'll almost understand it. Realizing that her sister's view of runes was somewhat skewed, the White Wolf decided to use the current incident as an example to explain to her the intricacies of carving a circle.

As he spoke, the white wolf picked up a small stone from the ground and drew three lines on the ground, which intersected at a point to form a spatial Cartesian coordinate system.

"Sister, you imagine this figure as a three-dimensional structure, come up with three straight lines in your own mind, and then make them intersect in pairs, perpendicular to each other. In order to make the explanation more vivid and easy to understand, the white wolf took out three small wooden sticks and arranged them into a corner of a cuboid to assist the black wolf in thinking, in fact, this is the teaching method used by his math teacher when he was in elementary school

"Uh-huh, I get it. The white wolf's explanation is very vivid, and the black wolf's brain is not stupid, but she has not been exposed to the corresponding concept.

"But what does it have to do with the portal?" the black wolf then asked, so far, she alone still has no way to establish the concept of spatial coordinates, and at this time she needs the assistance of the white wolf.

"This involves some physics and mathematics knowledge, you can first imagine a point, this point has no size, no length, nothing, it is just a point, this point is zero-dimensional, if you let this point translate along a certain axis, the trajectory it passes through is combined, it becomes a line, this line is one-dimensional, similarly, if the line is translated along another axis, it becomes a surface, this surface is two-dimensional. Moving on, translating the face along the third axis, the trajectory it travels becomes a cube, and the volume is three-dimensional. The white wolf said as he gestured with branches and stones.

"Well" the black wolf nodded as if she didn't understand, she didn't have a math education, so now these abstract concepts are a little difficult for her to understand.

"The world we are in is three-dimensional, and you can simply think of them as length, width and height, that is, these three vertical axes. The white wolf said, pointing to the three branches with his paws.

"Well, I can understand that, after all, we are not people on pieces of paper. The black wolf nodded, indicating that he understood.

"It's great if you can understand it, then I'll go on to say that now that we have established this spatial Cartesian coordinate system, it becomes very easy to determine the position of a point, as long as you know the length of the point from the origin on each axis of the coordinate system, the three lengths are set together, and this is the coordinate. In the same way, knowing the coordinates, we know the distance of the object from the origin, and this so-called origin is the point obtained by the intersection of three straight lines in pairs, knowing the coordinates and the position of the origin, as well as the direction of the three axes, we can determine the position of the other point. ”

"This concept of a coordinate system can be applied to the construction of a portal, if you want to teleport, you must know what the coordinates of the target portal are, the location of the origin, and the direction of the three axes, now you understand what the problem is, right?" asked the white wolf.

"Well, the question is, don't we know the coordinates of this point?" replied the black wolf, after a moment's hesitation.

"Correct, in fact, it is more accurate to say, not only the coordinates, we don't even have the origin and coordinate axis now, if we want to know the coordinates, we need an origin, this point cannot be selected casually, it must be a space rune array composed of space runes, and the three vertical direction axes are also the same, all of which must be composed of space rune arrays. The white wolf stretched out his paw and pressed it against the serpentine dagger.

"Sounds like a lot of trouble. The black wolf listened to the white wolf's explanation, and his brain was a little swollen.

"Well, the most troublesome thing is to establish an accurate vertical coordinate, if the angle is not vertical, if there is a little deviation, when it extends a certain distance, it will cause a huge deviation, and then we use this deviation data to transmit, we are likely to be transmitted to the stone, or the trunk of the tree. ”

"Sounds dangerous, but can't we build an accurate coordinate system?" Black Wolf suggested.

"But it's impossible to do. The white wolf replied categorically, if you want to achieve absolute accurate measurement, even the earth civilization that has developed to that point in science and technology can't do it, and the concept of absolute accuracy currently only exists in science fiction.

"Doesn't that mean that the problem of the accuracy of the portal cannot be solved?" asked the black wolf.

"It's not like this, we can actually make a few more reference points, so that we can ensure accuracy, but the price is that the time and resources spent, the complexity of the project will be greatly increased, with the current level of our territory, building a spatial reference point will exhaust all the mudstone resources currently stored, and we both have to bleed. The white wolf shrugged helplessly.

"Oh" The black wolf didn't expect that building a spatial datum point would be such a huge rune project, and she didn't know what to respond to at this time, she had a very low level of understanding of rune technology, and was actually limited to a few simple runes of the Wind Whispering Technique.

"And energy is also a problem, if you want to activate any space rune, you must use the power of the origin, that is, the power of the black as the driving energy, however, as the master of the power of the source, you should know how precious this power is, right?" The white wolf looked at the black wolf, his eyes full of helplessness.

"Sure, it's actually okay, during the time I was sealed, I've been saving up black power, although I used a little bit to create fake memories before, but now there are a lot left, many, many. The black wolf sensed the power of the origin that was separated from his soul, and nodded with great conviction.

"Yes, if that's the case, the energy is guaranteed. The white wolf was a little surprised at first, but after thinking about it, he felt that it was very reasonable.

"Wait, I have a question in mind!" the black wolf suddenly raised his paw and asked the white wolf.

"What's the problem?"

"If, according to you, on the opposite side of this portal, there should also be a datum point and three coordinate axes, wouldn't we just dig up those magic circles?" asked the black wolf, pointing to the dagger in the white wolf's hand.

"No, I don't dare to go over, you know that gray mist, it's too weird, God knows what's behind the portal. The white wolf stroked the dagger, his eyes revealing deep jealousy.

"That's just as well," the black wolf nodded in agreement.
