The limit of the distance that Chen Yue's mathematical level can reach at this moment is about 0.019 light years. Wang Liang's three-star system is 0.6 light-years away from the Weia galaxy, and theoretically only about 32 over-distance communication relay stations are needed to achieve real-time communication between the two places.

But in reality, Chen Yue will definitely not play to such an extreme. If one of the intermediate transit stations fails, or an accident occurs, the entire link will be broken. A more feasible plan is that Chen Yue will lay tens of thousands of transfer stations, each of which will take different routes and lay them in different places according to different distances.

In this way, even if 9,000 transfer stations are destroyed in an accident, the remaining transfer stations can still meet the communication needs.

In normal times, Chen Yue maintains communication through the optimal link through the relay of about 60 relay stations.

The ultra-long-distance communication based on the principle of quantum entanglement itself does not require time, but the operation and calculation of electronic components at the communication relay station takes a little time. On average, a communication relay will increase the communication delay by about 3.6 milliseconds, and 60 relay stations, the communication delay will be 216 milliseconds.

This communication delay is actually quite okay, probably similar to the delay when playing online games that are not very smooth in the Earth era, Chen Yue is barely acceptable.

Continuing to develop mathematics to seek a larger communication distance and continue to optimize the performance of the relay station to reduce the delay time of a single transit station are the two directions of Chen Yue's efforts in communication. However, this belongs to the water mill work worn by the drop stone, and it will be studied slowly in the future, but it is not in a hurry for a while.

At this moment, these transfer stations were directly put into space by Chen Yue. Under its own power, it began to fly rapidly towards the corresponding transit position between Wang Liangsan and the Wei A galaxy.

After reaching the predetermined position, these stations abandon the thrusters and use only their own thrusters, which have weak thrust, as a source of power for maneuvering. At that time, the volume of these stations will be reduced to about 10 cubic meters, which is a large ball with a diameter of about 2.7 meters.

The surface of these large spheres is coated with a high absorption rate of paint, whether it is radio waves or visible light, the reflectivity is extremely low, and it is considered to have relatively good stealth performance.

Because of the backwardness of science and technology, the density of the communication links laid by Chen Yue is almost dozens of times that of the communication relay station of the Southern Star civilization. Correspondingly, theoretically speaking, the probability of Chen Yue's transit station being discovered is also as high as dozens of times that of the Southern Star Civilization. Coupled with the gap in technology, this probability may be one or two hundred times higher.

But even so, Chen Yue was not at all worried that his transit station would be found out from the interstellar space by the rest of the forces. The reason is very simple, when something is difficult enough, even if it is one or two hundred times simpler, it is still extremely difficult, almost impossible to do.

When the communication relay station began to be launched and began to move towards Wang Liang's three-star system, the launch of the improvised spy detection satellite also began.

For this task, Chen Yue built hundreds of thousands of special electromagnetic delivery devices.

It's not that difficult to build, at least it's much less technically difficult than the electromagnetic energy cannon. In comparison, the demand for energy supply is larger and more complex. But it doesn't really matter.

Next to Chen Yue is an ice giant star. Although the elemental structure of ice giants is different from that of planets such as Jupiter and Saturn, it is still dominated by hydrogen. This equates to an almost infinite amount of fusion fuel, which can be sustained by as much consumption as possible.

Such an electromagnetic delivery device can launch three simple spy detection satellites in an average of one second, accelerate them to a high speed of 10,000 kilometers per second, and then launch them in the direction of Wang Liang's three-star system.

They are too small to slow themselves down at all, except for a faint attitude and orbit adjustment. But Chen Yue didn't need them to slow down either.

Just maintaining this speed, while passing through Wang Liang's three-star system, it is also a process of searching for Wang Liang's three-star system, why slow down?

At this rate, the first spy detection satellites will arrive at the intended location in about 15 years to carry out the search.

Each of these spy satellites can search interstellar space with a radius of 500,000 kilometers.

The volume of a sphere with a radius of 500,000 kilometers is about 5,236 million cubic kilometers. In such a vast interstellar space, the search mission is only such an insignificant little point.

It may seem incredible, but it's not that hard. Because the interstellar space, which is 0.2 light-years to 0.4 light-years away from the star, is unusually empty, and there is almost nothing.

The search target formulated by Chen Yue is not a specific thing, but a macroscopic object.

Only search for objects with a volume of more than one cubic meter.

And there is almost nothing like this in the empty interstellar space. As a result, if such a thing does exist in a certain space, it will be very easy for the detector to detect it once it is close to it.

Distance is the most important thing.

The difficulty of this matter is mainly that the interstellar space is too empty, and without a sufficient number of detectors, it is impossible to search every piece of space, and it is impossible to get closer to all potential macroscopic objects within 500,000 kilometers.

And Chen Yue did this by accumulating an unimaginably huge amount through his terrorist engineering ability. Then the follow-up is simple.

At this moment, on average, more than one million simple detection satellites are flying towards Wang Liang's three-star system every second. Chen Yue precisely adjusted the layout of the electromagnetic delivery device through the precise control of the launch angle of the electromagnetic delivery device and the weak power provided by the detection satellites to ensure that they could form a large net to "sift" through the vast interstellar space, leaving no fish that slipped through the net.

In the vast Dimension A galaxy, millions of factories operate day and night, producing a huge number of spy satellites. These spy satellites were then transported to the electromagnetic drop-off base and dropped into space through drop-off devices.

Although Chen Yue's efficiency and engineering ability have reached an unimaginably high level, Chen Yue knows that it will take almost ten years to truly complete this task, even if it is himself.

However, at this moment, the engineering task here in the Dimension A galaxy has been basically completed. The rest of the things are not technical or difficult, just run automatically.

It's time to go.

Looking at the dimensional A galaxy that was calm on the outside, but had almost turned into a mechanical ocean inside, Chen Yue felt a little emotion in his heart.

Secretly sighed, the huge but small human fleet set sail and embarked on a journey to Wang Liang's three-star system.
