Two months later. Xiao Yu finally discovered the first spy satellite from the Molian civilization. Because of their small size and mass, spy satellites can gain faster speeds than warships, so it's no surprise that equipment like spy satellites came to System One first.

"Well...... It seems that the Molian civilization is very smart. Equipped with only optical detection instruments? ”

After capturing this spy satellite, Xiao Yu manipulated the robot to inspect the satellite, and sighed, "A small device that does not take the initiative to send out any detection signals, only hides in the dark, and conducts espionage activities by capturing optical signals is the most survivable and the most effective." In the star system, I can shield all kinds of radiation, shield tachyon detection, but optical signals can't. I think there must be more of these spy satellites hiding in the shadows. ”

This spy satellite was captured by Xiao Yu at a distance of more than 40 billion kilometers from the star. It is not easy to find a small thing with a volume of less than one cubic meter, and the surface is made of special materials, and has good light-absorbing properties. In fact, Xiao Yu took the same approach to the Molian civilization. It's just that Xiao Yu is a little more ruthless, and in addition to this method, he also adopts the means of special combat soldiers and individual combat systems to directly infiltrate the enemy galaxy.

Tens of millions of satellites have been launched, ranging from stars to satellites, with the farthest reaching a distance of 200 billion kilometers. Their orbits are also different, some above the ecliptic plane, some below the ecliptic plane, and these detection satellites have only one mission, which is to do their best to find spy satellites hidden in the shadows and eliminate them.

Before the war officially began. The spy war has been launched in full swing before the head.

In the past two months, the No. 1 galaxy has been completely transformed by Xiao Yu, and the Haode detachable forging system was built when the last galaxy was resting and moved directly from the homeland spaceship, and the normal work began on the planet here, and a large number of raw materials were continuously collected, and after processing, it became a strong guarantee for Xiao Yu to complete various construction tasks.

At this stage, the galaxy's defense is temporarily guaranteed by spaceships, but a more complete defense system is being built rapidly, and Xiao Yujihua is building at least five galaxy-level negative matter cannons. That is, the kind that Xiao Yu once encountered, the kind that wiped out the entire Henan spaceship with a single shot, and even more powerful than this kind of cannon serves as the main liliang of the galaxy's defense, and then cooperates with various interstellar fortresses, interstellar mines and other weapons. Perfectly protect Galaxy One.

While managing the No. 1 galaxy well, Xiao Yu's tentacles are still extending outward. The three fleets sent out and the Legion of Intelligent Creatures are just an extension of their combat power. In the shadows. Xiao Yu is seizing the time to make spy equipment similar to the spy satellite of the Molian civilization that was captured this time, and is throwing it around the starry sky of the universe. The first batch has already embarked on a journey, and it is expected that in a year's time, it will reach the capital system of the Merian civilization and start exploring it.

"In a month's time, the Russos national spacecraft formation will reach the third system. It is a mineral planet, and although the value is high, the defense of Liliang is not necessarily strong. Well, let's occupy it first. Then they launched a pursuit of their escaped mineral transport ships, forcing the military base of System Two to send Liliang to the rescue. ”

Xiao Yu thought secretly.

A month passed quickly, and the formation of the Russo-Russian national spacecraft broke away from the curvature and revealed its body in the visible universe. A full half 500,000 ships were majestically suspended in the void, staring at the massive star in front of them.

It is a subgiant star that glows white and is about three times more massive than the Sun. Such a star already has enough capacity to produce A-grade metals, and the fact is not beyond Xiao Yu's expectations, the mineral mining base here is to collect A-grade metals.

A-grade metal is a good thing for Xiao Yu, not only to build space weapons, but also to build other things, such as spaceship shells, high-precision processing equipment, etc., are also used. It's just that Xiao Yu didn't have such extravagance in the past, and used A-grade metal to build these things.

"I hope to have a little harvest here, the construction of four space weapons has already depleted my A-grade metal reserves." Xiao Yu thought with some anticipation.

Without the slightest hesitation, 500,000 spaceships rushed into the star system, and the result was not beyond Xiao Yu's expectations, what greeted Xiao Yu was not a huge spaceship battle group, but an automatic defense system including automatic negative matter cannons, various trigger-type elemental decay bombs, antimatter bombs, deathlight weapons, etc. Without the cooperation of humans and spaceships, these firepower could not even stop Xiao Yu's progress, and before they were activated, a large number of specialized EOD spaceships had already arrived here and swept them away. Occasionally, there were missed automatic defense weapons, or they were far away, and they were also locked in by Xiao Yu the next moment they attacked, and then they inflicted a devastating blow on them through long-range strike fire.

System Three has become an empty city. Only on its two planets, the mineral gathering equipment that has long been blown up by the retreating Merlian civilization proves how prosperous it once was. But all that was gone was gone, and all the mining ships, miners, and the military liliang that matched them all retreated.

In this way, the No. 3 galaxy was successfully occupied by Xiao Yu without any danger. Xiao Yu quickly made arrangements, leaving a part of the combat spaceship here, as well as a part of the construction spaceship, a total of about 150,000 spaceships remained here, and the remaining 350,000 spaceships quickly left the No. 3 galaxy and embarked on the road of pursuit.

The 150,000 spaceships left here will build the No. 3 galaxy into another base for Xiao Yu.

"Mineral-gathering ships are not combat ships, and they will not travel at an average speed of six times the speed of light. In other words, in this period of more than three months, they have traveled a distance of less than two light-years at most. Very well, then let's start the pursuit. Xiao Yu gave instructions for the next step.

A full 350,000 spacecraft were scattered again, and with countless exploration satellites, like a large net spread out in the endless universe, a comprehensive exploration began.

Xiao Yu couldn't accurately lock the retreat route of these mineral transport ships, so it became inevitable to cast a full net. One thing is for sure, they are fleeing in the direction of the capital system, and the mineral transport ship must be loaded with a large amount of A-grade metals that are very precious to Xiao Yu. Therefore, this time the pursuit operation cannot be missed.

This pursuit operation was similar to the operation of a large army in the Cold Weapon Age searching for a small group of enemies on the plains. Small groups of enemies in the Cold Weapon Age may be hidden, and so will these mineral-transporting ships. However, no matter how much the enemy was hidden, the small group of enemies in the Cold Weapon Age will always leave traces, such as unintentionally left objects, traces trampled on the march, and even ashes left by fires. In the same way, these escaped mineral transport ships will also leave some traces.

Curvature navigation is not completely untraceable, and since space is bent, the matter in space will inevitably be affected and bent together. And the universe is not empty, even in the thinnest place of matter, even in the open space between river systems, there is a rather thin interstellar matter. If a vehicle that uses curvature to sail through here, the space will return to normal and imperceptible after being bent, but the structure of these substances will remain normal for a while after being affected by the curved space. By detecting the state of interstellar matter, Xiao Yu can determine how long ago and what kind of speed of the vehicle passed here.

Xiao Yu believes that when he fled after encountering the Molian civilization for the first time, the Molian civilization found himself based on this trace.

Now, Xiao Yu has used this method on the spaceship that tracked the escape of the Molian civilization. Depending on the space environment, the affected state of matter will last anywhere from a month to a year, and the retreat of the mineral spacecraft will start from three months ago at most, that is, as long as the search range is large enough, Xiao Yu will definitely be able to find the traces left by them.

The result did not surprise Xiao Yu. Hundreds of millions of kilometers away from the linear line between Star 2 and the Murlian Capital Galaxy, Xiao Yu detected this trace. Immediately, more than 100,000 spaceships gathered here, following this trace.

The reason why he didn't gather all the spaceships was because Xiao Yu couldn't confirm whether this trace was a real trace or if it was left by the other party to confuse the public. In order to prevent the large army from being led by the enemy's nose, wasting time on the wrong path, and finally missing the best time to pursue the enemy, Xiao Yu can only take this measure, that is, he will not put all his hopes on one line until the final clear result is obtained.

The final result proved Xiao Yu right. More than 50 billion kilometers away from this trace, Xiao Yu found this trace again, so another 100,000 spaceships gathered on this trace to track it......

In the dark starry sky, Shili, who is divided into two sides, starts a unique game of hide and seek. The outcome of this game of hide and seek will determine the life and death of many intelligent creatures, as well as the ownership of a large number of A-grade metals. (To be continued......)
