"When you used the ring to teleport just now, did you see some rooms that were light and unlit?" The instructor asked with a smile. "Yes, and I connected a bright one, and I can't teleport over, why is that?" SK1 asked, confused.

The instructor smiled and said, "If you can have these questions, it means that your mental concentration just now is very high. This is because the Authority has a number of areas that are open to the public, and these areas use extremely precious and rare "anti-traversal" materials crafted at the national level. Speaking of this, SK1 asked curiously: "What is the "anti-traversal" material? The instructor paused for a moment and said: "The so-called "anti-time-traveling materials" actually use some space-influencing materials, that is, to make some cross-cutting and teleportation media unable to locate the space-time where these materials are located. This process can only be done by manual and machine assistance, which is extremely inefficient and has a very high failure rate, and there are very few materials. So there is only a small amount of stock. Most of them can only rely on the influence space, but this is only a semi-blockade, and it is still possible to teleport into some special media with strong spiritual power, but it is more difficult. There are only some materials that can be made into materials that affect time, but they also affect time, and they don't use media, but they can walk through directly if they know it. It is only available at the headquarters of some important international organizations. This is to prevent anyone from crossing by surprise, and there are never more than 5 of these places. But none of this is really an "anti-traversal". And only when the materials of time and space coincide, a place called "forbidden time and space" will be produced, which is a place where it is impossible to travel and teleport. Nowhere else is it except our Authority. And you can't travel through the past because it's through the training room, and there are special materials. And without the authority of the instructor or above, you can't get in and can't get out. ”

After the instructor finished speaking, SK1 asked again: "Then I saw some rooms with golden light, are they made of "anti-traversal" materials?" "That's right, that's right, and the red light you just emitted from the ring is to protect you from falling into a state of mental confusion. And it is extremely rare to be able to do this for the first time. You are very talented! SK1, who was praised by the instructor, was a little shy and immediately asked, "How many rooms like this are there?" ”

The instructor paused for a moment and said in a deep voice: "There are about six anti-space teleportation places in our bureau, one prohibits time and space travel, and more!" The instructor calmed down and said, "Our bureau is an anti-time travel material, and there is no way to know the current time, but it is just a coat on the surface. But the financial resources of the characters are definitely beyond your imagination! ”

"Wow!" SK1 couldn't help but marvel when they heard this. Yes! With such a huge amount of resources poured into this space-time supervision administration, then the forces behind this organization are incredible!

Thinking of this, SK1 asked, "What is the "forbidden space-time" used for?" When the instructor heard this, he said with a serious expression: "This is not what you need to know now, you just need to know that these places can naturally have their reasons if they are not opened, don't try to explore, and when you should know, you will naturally know." ”

SK1 nodded, then said, "Then they can't get in if they want to?" And in the place where I live, except for me, it is not lit, is it also made of anti-crossing materials? ”

The instructor smiled and said, "If I answer your first question, I will answer the second one." The instructor said: "All anti-crossing materials will be set up with one or more "keys" that can enter, so that once someone wants to enter, it is equivalent to using them to open them, how can they not enter?" Once the key is set, it cannot be changed. So the second question doesn't need me to talk about, right? The instructor asked. No, I've figured it out, because the bureau doesn't let us mess with other people's rooms, so an identification device is set up. SK1 replied.
