According to the calculation of the diameter of the island by the search and rescue team, if there is such a fast passage, a normal flying person can fly from one end of the island to the other, and the total time consumed will generally not exceed an hour if calculated according to the unobstructed flight speed. —that is, within two hours.

Considering the inevitable obstacles and the need to slow down in the building, the whole time will be within three to four hours.

Below this speed, flying people can't be said to be racing swords, but jumping - in the case of very complicated road conditions, relying on jumping to advance in space is far faster than using flying swords.This point, they have already seen it on the island of prophylaxis.

But now, whether it is from the mouths of people who have lived in this building for more than 30 years, or from the current speed of action of several searchers, the search and rescue team has come to a conclusion that is completely contrary to this common sense-in this island On the road, the minimum time to complete the journey normally exceeds 8 hours.

One must know that the speed of the flying sword, even inside the building, is quite astonishing.Even if calculated at a conservative rate of 60 kilometers per hour, the entire path would exceed 480 kilometers, and the diameter of the entire island would barely exceed hundreds of kilometers.

What kind of path can allow four people from different directions to walk from one end of the island to the other along different routes, but the path they travel is far more than twice the normal value? ——The conclusion is naturally simple, it is a detour.

If it is in one direction, there is a phenomenon of detours, which is not surprising.

After all, it is the first time for them to come to this island. Even if the search and rescue team has everyone's location information at any time, even if the search and rescue team can make a comprehensive judgment on the path they have walked, even if the search and rescue team can always know the relative position of the four people. distance, and make adjustments at any time—to prevent them from unknowingly coming together and wasting search area.However, in the face of unknown road conditions, a slight deviation is still a normal thing.

But the search and rescue team arranged four people each time.

In a fixed three-dimensional space, starting from the same entrance and then exiting from the same exit—based on the route planning of the search and rescue team, the itineraries of the four people are almost spatially symmetrical.

This also means that the average search efficiency of the last four people must be close to an average.Generally speaking, this average value should be a number that can be easily calculated based on the size of the space.

On the island in front of them, four people acted in accordance with the requirements of the search and rescue team, but they couldn't get out of the theoretical numbers calculated by the search and rescue team.

The reason is very simple. The search and rescue team can easily come to the conclusion that there is an impassable area in the buildings on this island as long as they calculate the travel route of everyone.

In an easier-to-understand way, the paths walked by the four people seem to be walking along the six sides of a cube.

And everyone knows that in a three-dimensional space, the shortest path is often the line formed by connecting diagonal vertices.

This path exists in other islands, but here, it disappeared strangely.Although the search and rescue team controlled four people and tried to detour around the center of the island from four different directions, these attempts always eventually encountered walls.

The short-haired guest followed the guidance of the search and rescue team and finally stopped in front of a wall.

According to the search and rescue team, there is likely to be something they are interested in hidden behind this wall.

The walls are very ordinary, and they don't look any different from ordinary metal walls.In Ascension Realm, almost most of the islands have metal walls like this.Many islands can even see these exposed metal parts directly after the outer sand and stone have peeled off.

In the core area of ​​Ascension Realm, which is the place occupied by many great sects, once such a metal structure approaches the guarded territory of other sects, it will be immediately controlled.People inside will be expelled, or even killed directly - because in the early days, there were examples of some sects using these metal structures as bunkers to attack other sects.

There is no gravity in Ascension Realm, and these metal structures are comparable in strength to Feijian—that is to say, these metals can almost perfectly resist Feijian's attack.

To flying people, this seems to be a natural battleship in Shengtian Territory.If this is the analogy, there is no doubt about the other sects, each sect is an aircraft carrier full of fighter jets.

Everyone knows that even an aircraft carrier will be completely unable to withstand the opponent's direct firepower if it is approached by a battleship.Therefore, the best way to deal with these iron lumps is to eliminate them directly before they approach.

And the tools used to disassemble these metals... a long time ago, they were actually just common magic tools used for work in each sect, and were more used for the internal renovation of the sect.But now, this kind of magic weapon has long been spread far and wide with one person, and this magic weapon has naturally become a magic weapon that everyone keeps secret.

The short-haired guest has lived in the Ascension Realm for more than 1400 years, and he has come into contact with countless types of magic weapons.But it was the first time for the Qianyang finger that I got today... Not to mention, there was a piece of phantom stone next to the Qianyang finger.

Although the light emitted by this piece of virtualization is usually too dim to be noticed——but in this completely dark world, it is still refreshing to watch.

The myth of Qianyang finger and Huaxu stone has appeared since the Samadhi real person, and it has been 700 years since one is present.The short-haired guest never thought that one day he would be able to use this legendary combination in person—not to mention the Void Transformation Stone, even if it was the Spirit Stone, he had long forgotten the feeling and experience of using it.

"Don't be nervous," the collection team saw the cautiousness of the short-haired man, "Qianyang Finger is a very smart tool... Hold it up, aim it, put the phantom stone in your hand...you can take some Reiki, because your cultivation base is not high, it is very likely that the aura in your body will be drained in the instant you use it..."

I'm afraid the short-haired guest would never have imagined that the person commanding him in real time at this moment is the user of this legendary combination, the real Samadhi himself.The search and rescue team just used voice as a middleman.

With the activation of the Qianyang finger, a faint red light appeared, and the short-haired guest discovered that the movement of the Qianyang finger was not controlled by his own hands, but his own brain—the Qianyang finger seemed to be able to read and use Every operation instruction of the operator, and execute it precisely.

In front of the thin laser, the seemingly indestructible metal seems to be like a cake that has been cut by a knife... After ten seconds, the cutting operation has been completed.

In front of them, a perfectly circular metal plate with a diameter of two meters was cut out - but it remained in its original position.However, the short-haired man stretched out his finger and gently pushed the round metal plate away, as if he had opened the gate of a palace.

The light of Qianyang Finger has disappeared, and the surroundings have fallen into darkness again.But the flying man's dark vision still allowed the short-haired guest to see what was behind the wall for the first time.

Nothing.

Moving the door behind him, the short-haired guest no longer has any visual obstacles in front of him, which made him see what he saw just now more clearly.

Still nothing.

The eyes of the short-haired guest were already excited, and he almost subconsciously wanted to take out the flying sword from the bag behind him... but was stopped by the search and rescue team.

"Wait a minute," the search and rescue team said, "let me take a look first."

The short-haired guest raised the piece of glass in his hand, and aimed the non-luminous side at the empty place in front of him.

Yes, as the search and rescue team expected.Behind the wall, there is a huge space.

There is nothing inside but space.

No buildings, no people.No sound, no floating objects of any kind...

In front of the short-haired guest, there is a huge empty space.He took out the Qianyang finger and adjusted the power to the minimum - the laser has almost no lethality under this power, and it is only used as a visual indicator and guidance.

The short-haired man controlled the red light, and let it gradually sweep along the edge of the huge space in front of him—the air inside was very clean, and the laser did not leave any marks in the air, only in front of them, very far away place, leaving a faint red spot that is barely visible.

The short-haired guest followed the red dot with his vision, and quickly outlined the outline of this huge space—it was a huge square space.

After taking back the Qianyang Finger, the short-haired guest almost couldn't wait to take out the flying sword behind him, ready to let it carry him, and went to this space for a field visit.But the search and rescue team stopped him again.

"No," the short-haired man was a little confused by what the collection team said, "there is no wind."

"No wind?"

What the search and rescue teams were referring to was that the instant after they cut through the wall, there was no pressure difference on either side of the wall.

The laser scanning can basically determine that the huge space in front of him is completely isolated from the outside buildings.In other words, the entire building complex outside can actually be counted as the shell of this square space.If it is really completely closed - then after such a long period of isolation, there must be an inevitable pressure difference between the inside and outside of the room.

In the Ascension Realm, the flying people still need to breathe. Since they need to breathe, they naturally need to consume oxygen—the oxygen content in the air of the Ascension Realm is about 33%, which is nearly half more than that of the earth .

At such a high oxygen content, in general, a chemical reaction between the metal and the oxygen is unavoidable.

Regarding this point, it is the general conclusion that the search and rescue team has drawn through testing metal samples.

Although the metal technology used by aliens has excellent performance in anti-corrosion—but as long as this world is still in the same universe as the earth and shares the same set of physical laws, it means that as long as it is a material, no matter what the formula is, how Strong, under the influence of a long time, there will always be a little reaction.

The main component of these metals is an alloy mainly composed of aluminum and titanium. The performance in terms of oxidation resistance is excellent-but under the long erosion of 1400 years, the performance of metal materials will inevitably weaken.

In other words, if this is a truly sealed space, then oxygen will inevitably react with the metal to produce solid oxides—the internal pressure will definitely be lower than the outside.

In this way, the moment they open the door, this negative pressure will definitely have a suction force on people.

But the short-haired guest just now did not feel this pressure difference at all.The short-haired guest remembers very clearly that after the cutting is completed, the entire cutting surface is almost motionless-he pushed it away with his hands in the end.

This means that in this seemingly confined space, there is actually a channel to communicate with the outside world—but... they have already scanned it with a laser, and even the short-haired guest used the bright flashlight he brought to confirm again.

The entire square area is indeed completely enclosed.

"Try to control Feijian to fly over alone...slower," the search and rescue team said to the short-haired guest, "Stand back."

The short-haired man didn't understand what the search and rescue team meant, but he did it anyway.Within a few seconds after Feijian flew out, he understood the intention of the search and rescue team - Feijian disappeared.

Right in front of the short-haired guest, with his eyes fixed on him, the flying sword disappeared as if it had been melted into the air.
