"It's ......"

In this case, even if Yuan Yi was a little surprised, it was understandable, but it was better to say that his reaction was relatively calm now.

"This is the rift in space." The voice of the North House is still as gentle as an old-fashioned table clock, lacking in ups and downs, but this sound is also appropriate for popular science: "In this world, it is not as complete as we imagined, it is full of countless faults and cracks, which lead to their own different coordinates and timelines, which is the principle of the appearance of 'Drifter' in Bam's mouth." ”

"Are they really from another plane?"

"Not necessarily, it could be a timeline in the past or the future, and the biggest crack in this is what we call the 'nest'."

"What...... What the!? ”

Impactful dialogue.

Does Kitataku mean that the deep sea is an enemy from another world?

"No, that's not what it means," as if he had spied on Yuan Yi's mind without authorization, Beizhai shook his head: "There are many secrets of the deep sea, most of which are not known to the current human race, as I said just now, the crack does not necessarily point to other worlds or timelines, and it may also form a complete channel with another crack somewhere in this world, and the Oar of Lofe Carter can do the same thing as this." ”

Inexplicably, it was pulled back to the original topic, but what Yuan Yi wanted to hear now was about the nest and the cracks, and he was super concerned!

However, Beizhai didn't mean to go deeper, maybe for her, it was also a puzzle that bothered her. The only thing she is responsible for explaining now is how to use the Lofe Carter's Oar and its corresponding functions.

"If the world is compared to a long corridor, then it is a long straight line that cannot be seen at both ends."

As Beizhai spoke, a corridor really appeared in the chaotic and incomplete world where Yuan Yi and the others lived, but this thing still didn't feel the slightest reality, because it appeared out of thin air, and except for the corridor where Yuan Yi and the others were standing, and the wall next to it, everything else, such as the ceiling, and the other wall were still mixed color spaces painted by abstract painters.

"And the coordinate point that connects each space is a door."

As far as the north house is concerned, doors appear one after another on the snow-white walls, extending towards the two wings.

"In other words, with the paddle of Lofe Carter, you can connect the coordinates of two different places." In fact, there is no need to explain this, because Yuan Yi has already experienced such an unbelievable trip twice, he reached out to the doorknob in front of him, glanced at the north house, and saw that the other party did not stop it, so he opened the door, but walked out of another door on the side.

"Interesting, are there any restrictions on this thing?"

"Yes." Kitazhai answered clearly.

Yuan Yi had heard some things from Bam before, but those were just some inferences made by Bam based on the literature records and the characteristics exposed by Beizhai after using this prop, and they were not as accurate as the description of the person concerned.

"The most important limitation of Lofe Carter's oars is cognition."

"Cognitive?" Yuan Yi was inexplicable when he heard this, shouldn't it be the calculation of spatial coordinates?

Beizhai looked at Yuan Yi with those disdainful eyes, as if to say, don't interrupt you monkey when I speak.

Although he was unhappy, Yuan Yi could only pretend to be humble and push his hand, making a low posture that you would continue to have.

"The reason is very simple, for example, the two doors here, because you are well aware of their existence, so you can easily reach one end to the other with the Lofe Carter Oar, but when you force your way through a door and can't find the right exit, it will cause spatial disorder, and the better result is to be randomly teleported to a certain place in this world, but if you are lucky, you may even be lost in the crack forever."

"In other words, in order to use the Lofe Carter Oar, do you have to know where the exit is in advance?"

"Hmm. In the example of comparing the world to a long corridor, the limit of what we can reach is what we can see with our eyes, and what we can reach or reach with our feet. ”

As soon as Beizhai said this, the doors in his line of sight opened automatically, but the doors farther away were still closed.

Yuan Yi understood what she meant, which means that there are places in this world that can be teleported, but there are many more that cannot be touched.

This may sound vague at first, but the layman's explanation is that if you want to use the Lofe Carter's Oar, you must have an idea of where your connection begins and ends. If you're going to a place you're completely unfamiliar with, the probability of achieving your goal is almost zero, and even if you have some knowledge of where your goal is, it's a huge risk to use Lofe Carter's Paddle without making sure it's true.

"So the location of the entrance and exit must be chosen where there is a door?" After understanding this foundation, Yuan Yi asked again.

"Not necessarily, but at least it won't be like a wall to seal you inside, and at the same time, it can avoid a series of problems caused by your sudden appearance at a certain coordinate point, and most importantly, using the door as a node has the highest success rate."

In fact, you only need to say the last conclusion, Yuan Yi spit out a little in his heart.

After listening to a series of introductions, Yuan Yi felt as if he could try to use it.

"Can I use it to give it a try?"

Beizhai nodded, handed the paperclip to Yuan Yi, and just as she made this move, all the surrounding illusions disappeared, and they returned to the original cabin.

"What am I going to do?" In Yuan Yi's opinion, this thing is just an ordinary paper clip, does it depend on people to activate this thing?

"Concentrate and then say 'Restart'"

Yuan Yi did so.

The next second-

Huge data emerged, and the surrounding horizons became different again, but what appeared in front of Yuan Yi's eyes was no longer a corridor, but a vast void space like a starry sky, with doors of different shapes and irregular arrangements floating in the middle, making people surprised and dazed.

"The space I opened up doesn't seem to be the same as the one you just opened?"

"Of course, because it's the embodiment of your inner cognition."

"What's next?" Willing to ask.

"The next thing is to connect the beginning and the end, think as much as you can about where you're going to be, and where you're going, so that there is a 'connection' between the two."

"The starting point for me is the door of this room, and if you want to connect, you can go to my own room." At the beginning, Yuan Yi didn't want to make it too difficult, and whether it was the room in the North Mansion or his own room, Yuan Yi had a clear enough impression in his mind.

Just when he wished so, the paper clip in his hand, the Paddle of Lofe Carter, shone brightly, and then stairs appeared in front of the door in front of Yuan Yi's eyes, and then connected to another door at one end of the space.

When this succeeded, the room in the north house returned.

"Did it work?" Yuan Yi asked, to be honest, he didn't have the real sense of success.

"I don't know, but I'm sure it's connected to a certain node." Kitataku replied.

Then, there is only one way to verify.

Yuan Yi took a deep breath and put his hand on the doorknob.
