The night was quiet.

The snow outside had stopped, and the whole world seemed to be asleep, and there was no noise around, so quiet that you could hear the sound of the oil lamp beating in the room.

"Whirring ......"

Pandora, who was leaning on the corner of the wooden bed, seemed to be a little uncomfortable, frowned and shrunk her neck, changed her position, and continued to sleep with her eyes closed.

Richard glanced up, dipped the tip of a quill pen in ink, and landed on the papyrus, writing as he pondered.

The tip ......of the quill rubs against the papyrus paper, making a subtle sound, and quickly drawing out ink blots to form words.

"After testing, the Iron Ring has shown a phenomenon that conforms to a series of descriptions of space props in the conventional sense.

One of the main properties is that you can put a certain amount of objects into a storage space. The storage space, on the other hand, is isolated from the outside world and has a normal time lapse and is affected by gravity, but not by the rest of the external forces (as evidenced by the second and third tests).

In order to show this effect, as far as is known, there are three aspects of technology that can be achieved through development: rapid 3D printing technology, space compression technology and space transfer technology.

Rapid 3D printing technology, that is, rapid prototyping technology, is based on digital model files, using powdered metals, plastics and other adhesive materials, using digital technology material printers, and constructing objects by printing layer by layer. On the modern earth, it has been widely used in jewelry, industrial design, architecture, engineering and construction (AEC), aerospace, firearms and other fields.

It is foreseeable that with the continuous development of technology, after breaking through the synthetic protein printing technology and atomic recombination printing technology, it is theoretically possible to print all objects and even life in the world.

Therefore, the iron ring can be explained by 3D printing technology: when an object tries to be placed in the iron ring, the iron ring will quickly scan the exterior and interior of the object, quickly model it, and then use technology to destroy the object, only store the digital model file of the object, and look as if the entire object has been stored.

When it comes to removing an object, the Iron Ring will perform a quick 3D printing process, resynthesizing the same object as the original according to the digital model file of the saved object, which looks no different from taking out the stored object.

But this technology obviously consumes a lot of energy and materials, causing great waste. When storing living creatures, it is unreasonable to kill living creatures and then create another living thing. In addition, the technology of material annihilation, and the technology of unlimited storage of raw materials, are obviously higher than 3D printing technology. On top of that, this technique locks on all states of the object after it is placed (scanned), and exhibits a time freeze that does not match the phenomenon observed by the test (the hourglass flows), which can be largely ruled out.

After excluding rapid 3D printing technology, it is space compression technology. This technique is a means of compressing a large amount of space into a very small volume, that is, the iron ring can be seen as a cleverly folded box, which can hold far more than normal objects.

In this case, the substance placed in it does not disappear, and the outside world can also affect it. Then the iron ring will become heavier and heavier as more and more substances are put in. After all, internal objects are subject to all the forces from the outside world. This does not correspond to the phenomenon observed by the test (the Iron Ring has always been light) and can be ruled out.

Finally, there is the space transfer technology, which can also be called the space folding technology (which is different from space compression). According to Einstein's theory of general relativity on modern Earth, it can be determined that gravity can cause space-time to bend, so that the distance from one point to another in three-dimensional space is not necessarily a straight line.

That is, from one location to another, although there is an extremely long distance, as long as the bending of space-time coincides with the two, it can be reached instantaneously. For example, this is akin to dropping an object on a high mountain, and after passing through some folded point in space, the object falls directly into a set sealed box thousands of miles away.

From this point of view, the Iron Ring is not a space prop, but more like a space door, and the storage space it connects to is the real space prop. When you put something in the Iron Ring, it doesn't actually exist inside the Iron Ring, but there is a storage space in the middle of nowhere. This inference explains basically all the phenomena observed in the test.

For example, it is precisely because the iron ring and the storage space are in two overlapping but different spaces that the force on the iron ring will not affect the storage space. The force on the storage space, the mass it bears, will not act on the iron ring. So the Iron Ring is just a door, a door that connects to storage space in an unknown location. ”

"Rustling ......"

The movement of his hand paused, dipped in ink again, and Richard pondered for a moment before continuing to write.

The result of this inference is obviously contrary to common sense, but it is in line with science. In this way, the iron ring can also be used for some different uses than storage.

After testing (13th and 14th tests), it was determined that the storage space connected by the Iron Ring was extremely strong. This may have been deliberately made to ensure sturdiness under a sufficiently large gravitational pull. And this strength can be used to perfectly defend against all types of flying items, and be immune to their damage.

This is because, as long as it is used properly, the spatial entrance of the Iron Ring can be used as a defensive shield. Unlike shields, which can only block attacks, the Iron Ring can absorb attacks. For example, a high-impact ice gun can be fired directly into the Iron Ring and loaded into the storage space. Due to the difference in space, the Ice Gun will burst out of attack power in the storage space, and when it is taken out of the Iron Ring again, all the power will disappear and no damage will be received.

This defense is absolute, and it is completely infallible, but there are certain limitations. On the one hand, you need to make sure that the attack is accurately absorbed into the Iron Ring. On the other hand, absorbed attacks explode in the storage space and can damage the objects stored in it. If it is just to defend against a cloud of acid, let the acid enter the iron ring and corrode the precious material, it is obviously not worth the loss, it is better to dodge, or use other methods to defend.

Therefore, this defense of the Iron Ring is only suitable for responding to unavoidable and potentially life-threatening attacks in a crisis situation. After all, life is more precious than what is stored. This can be used as a hidden hole card, a hidden 'Absolute Defense of Space Transfer' hole card. ”

"Rustling ......"

The quill paused again, dipped in ink, and Richard continued to write.
