The surface dimension on the starry sky pattern is speculated to be between three dimensions and two dimensions.

Thinking of this possibility, Xu Ran immediately ran to the office, turned on the computer, connected to a server in the High Energy Space Physics Laboratory of the University of Science and Technology, and downloaded a simulation tool from it.

After this simulation tool was downloaded and installed, Xu Ran quickly built a two-dimensional coordinate axis in it, and then put the three-dimensional image of the earth on those two coordinate axes, and then added his position to a point in the three-dimensional image of the earth, so that it would run automatically.

In the process of operation, Xu Ran calculated the three-dimensional coordinates of space on the earth with his fixed points, and then calculated an approximate two-dimensional coordinate point of the plane by the distance between several white bright spots in the starry sky pattern in the key, and then input this value into the simulation tool for calculation.

The process of calculation is a bit complicated, and it has to rely on the simulation tool to calculate, and if it is a high-dimensional spatial coordinate, it needs a supercomputer to assist in the calculation.

Fortunately, the computer was brought back from the fragmented space, and the configuration of the server that completely hung the top of the earth was completely suspended, and it took about half an hour of operation to finally calculate the coordinate value of the surface dimension.

After obtaining this coordinate value, Xu Ran put it into the dimension of the starry sky pattern of the space key, and through the coordinate axis, he obtained the three-dimensional coordinate positions of the two points on the earth.

Putting this three-dimensional coordinate into the three-dimensional image of the earth for positioning, Xu Ran was shocked to find that the location of the two coordinate points was in Xia Cheng.

To be more specific, the direction where they were in Xia City was in the area of Shahaigouzi.

From this situation, Xu Ran couldn't help but think of when Xia Tanhe escaped from the ancient tomb with his teacher Song Wenli, they inadvertently walked onto a mysterious altar and teleported to the outside of the ancient tomb through the altar, thus escaping back to the archaeological camp, so that Song Wenli got the opportunity to rescue and saved a life.

Since Xia Tanhe was able to use the mysterious altar to carry out directional spatial teleportation, it meant that there must be facilities similar to the guiding force field arranged by Xu Ran in that ancient tomb.

Thinking that the rain bracelet came from an altar found by Huo Sizhen, it was a prop used by mages to worship the sky and pray for rain in ancient times, since it was to pray for rain, then it was related to water resources, which made Xu Ran have a speculation.

Ancient mages may not have used rain bracelets to pray for rain, and it would be unscientific to expect rain from above, and it is highly likely that they used directional spatial teleportation to draw water from another place that had the water resources of an underground river to achieve their purpose.

In this way, the wisdom of the ancients should not be underestimated.

Since the ancients would use directional space teleportation technology, then one of the props they used was most likely to include the star core meteorite, so the two coordinate points with energy guidance that Xu Ran found when he returned to the earth in the debris space should be the altars arranged by the ancients.

One of the two altars was inside the ancient tomb, and it was very likely that it was the Zhending Altar that Huo Sizhen was trying to find, and the remains of the altar outside were also in a cave, and the environment they were in, according to Huo Sizhen's rough description at the time, it was very likely that there was a naturally formed force field inside.

But what made Xu Ran feel strange was that if the natural force field there had always been in a state of activation, then Xu Ran had been frequently teleported between the Fragment City and the Earth before, and there was still a very high chance that he would be accidentally teleported to that place, but it didn't happen once.

And this time, Xu Ran accidentally discovered those two natural teleportation points, which showed that those two altars were very likely to have been activated by human factors.

Could it be that the teacher and Zhu Guodong had already entered the ancient tomb and discovered the altar, and inadvertently activated it?

But the other altar is still some distance away from the ancient tomb, how is it activated, if it is said that it is automatically activated, Xu Ran does not believe it.

Suddenly, I thought of the last time I sent Xia Tanhe to Shahaigouzi on the return trip, I saw Huo Sifar appear in Haisha Town.

Xu Ran thought to himself, could this matter be related to Huo Si Far, could it be that Huo Si Faer took people to the ruins of the altar where Huo Si Zhen had been, and thus activated the force field?

didn't think about it so much for the time being, Xu Ran was a little excited now.

Because through this incident, Xu Ran's inspiration was suddenly stimulated.

Since the ancients were able to use the star core meteorite to arrange directional teleportation, then Xu Ran had that space wormhole-like cheat, and now he had calculated the coordinates of several point surface dimensions, so Xu Ran could use the knowledge of modern space science to easily achieve directional teleportation, and he could be more accurate and precise than the ancients.

Thinking of this, Xu Ran immediately took action.

In fact, there was no need for too complicated arrangement and erection, and the teleportation point he had temporarily placed in the northwest corner of the warehouse could remain the same.

Xu Ran only needs to reverse the uniform magnetic field coil arranged in the laboratory, which is equivalent to reversing the guiding force field, just like the principle of homosexual repulsion and opposite-sex attraction of magnets.

After reversing the guidance force field of the laboratory, Xu Ran added the spatial coordinate positioning, and took out the star core meteorite on the rain bracelet.

The meteorite on the rain bracelet contained much less energy than the football-sized meteorite, and when Xu Ran reversed the guiding force field, the teleportation point in the northwest corner would form an energy attraction here, so as to achieve the purpose of teleportation.

According to this line of thought, Xu Ran immediately began to arrange.

After spending about half an hour, the force field in the laboratory was reversed, and Xu Ran used the meteorite on the rain bracelet as the driving core to make a simple dispenser.

When the transmitter was ready, Xu Ran casually found a place, and then turned on the transmitter, and at the same time turned on the space key, and after using the key to locate the dimensional coordinates, he only took a few steps, and the whole person disappeared in place.

The next moment, Xu Ran's figure appeared at the location of the coordinates of the teleportation point in the northwest corner.

The directional teleportation experiment was successful.

Xu Ran deliberately looked at the energy scale on the space key and found that there was no slight change.

This shows that directional spatial teleportation in the same dimension does not consume the energy on the key, only the spatial teleportation between different dimensions, so that the Blue Star World to which the fragmented space belongs is a parallel world in a different dimensional space with the earth, so the conversion of the two dimensional spaces will consume the energy on the space key.

The success of this directional space teleportation experiment, Xu Ran's heart was ecstatic, and he quickly had a more complete plan for setting up a teleportation point.

In addition to setting up teleportation points between the debris space and the earth, Xu Ran decided to set up some directional teleportation points between different regions of the earth in the future.

With a directional waypoint, the benefits are self-evident.
