"The initial acceleration is 7,200 kilometers per second, and the cruising speed in space is as high as 110,000 kilometers per second. It is full of new warships equipped with energy shields, three flagships at the 1500-meter level, 150 warships at the 1,000-meter level, 500 ships at the 800-meter level, and 1,000 ships at the 600-meter level..."

Xu Xiaobai looked at the data displayed on the screen and said intimately: "The last time the 600-meter ship was already a flagship, but now the 600-meter level is at the bottom of the fleet. This means that the other party not only fully advanced to the third-level civilization, but also has a qualitative leap in productivity.

It seems that the golden belt of murder and arson is suitable there. It has been less than 600 years since I touched the bait. Using a biological civilization to trade a complete set of technology for energy shields has caused the strength of civilization to undergo earth-shaking changes in a short period of time. This is a tough battle!”

Didi!

Suddenly, Xingtu issued an alarm, but it was an outer detector close to 0.6 light-years outside the orbit of Yuantianwan 4C.

118,000 kilometers per second! According to calculations, it is estimated that the opponent's fleet will reach the original Tianwan 4 C orbit position in about one and a half years.

"In this direction, the angle is a bit tilted. Is the target the remains of Tianwan Si C?"

On the displayed image, the heading of the Eight Claw civilization directly points to a blank area, but that area will circumvent the main remains of Tianwan Si C in a year and a half and a year to reach that location.

The picture lasted less than two seconds, and the detector was terminated by an accurate high-energy light from the Octopus civilization. In the data transmitted back, the Octopus civilization has activated active detection. The range of active detection is as high as 800 million kilometers, and all suspicious large pieces of matter within the cleaning range.

"The last time I remember correctly the active detection distance was 300 million kilometers, but now it has increased to 800 million kilometers. Did the third-level civilization that traded with the Eight Claw civilization even sell the active detection technology?

This is why hormones don’t develop so quickly after taking them, so I want to sell myself!”

Seeing the data sent back, Xu Xiaobai finally couldn't help but swear.

The distance between the active detection and the divine white mouse has just exceeded 300 million kilometers, and the other party's active detection has reached 800 million kilometers.

Although the civilization level reaches this level and can be detected as long as the other party starts active detection, the signal source can interfere with camouflage. Whether the other party's position distance can be discovered can only rely on its own active detection technology.

Before there is no super-light detection method, it goes without saying that the detection wave rebounds in active detection technology, and this is the principle used by the radar on the earth.

However, as long as the materials used by interstellar civilization are not close-range irradiation and high-intensity detection waves, it is absolutely fine to absorb all the detection waves and not reflect them back. At this time, active detection technology needs to use another method.

When two different detection waves are transmitted, these two detection waves can interfere with each other and generate continuous echo signals. When the originally continuous echo interrupted, you can know that the detection wave is absorbed. Then, based on the speed of the detection wave and the echo interrupt time, the orientation of the enemy warship can be calculated.

This technology that can ensure that the mutual interference between the two detection waves is maintained at a longer distance without attenuation and ensure the clearness of the echo is a series of technologies. It can only be tested and summarized and then optimized. If the technical optimization is not possible, if it exceeds a certain distance, it will be severely distorted and lose sight.

In war, the active detection distance is crushed. Once the distance between the two sides is widened, you are blind and you are a situation where you can only be beaten passively.

"Star Path, smash all the large meteorites on the route of the eight-claw civilization fleet, smash all the larger wreckages of Tianwan 4 C, and once again invest a group of space thunder and lurkers. We rely on Tianwan 4 B as defense, I don't believe that the opponent dares to attack without enough material supplements!

In addition, the rays of stars are too far away and the intensity is too weak and can be directly absorbed by the opponent. Some active light source bullets can be arranged at a distance along the way."

The war on Earth is about information warfare, and the interstellar warfare is even more about information warfares. At least when the warships collide beyond the visual range, whoever has the information advantage will have the advantage of the battlefield.

Just like the first one to fight the Octopus civilization, the other party didn't know that Xu Xiaobai mastered the ultra-long-distance detection method, and did not know that Xu Xiaobai belonged to a biological civilization. When the fuel silo of the warship was broken, he had the ability to resist. In the end, Xu Xiaobai successfully attacked and counterattacked due to information aberration. Otherwise, Xu Xiaobai would have been caught back and stripped naked and placed on the test bench like a rare animal.

A year and a half passed in a row. The detectors arranged by Xu Xiaobai along the way were constantly shattered. The Octopus Civilization Fleet was so cautious that even the slightly larger meteorites would be shot over.

When the Eight Claw Civilization Fleet arrived at the periphery of Tianwan 4 C orbit, it ignored Xu Xiaobai, who was far away in Tianwan 4 B, nor entered the remains of Tianwan 4 C. Instead, the engine in front ignited the entire fleet began to slow down, and finally stopped 100,000 kilometers outside the original Tianwan 4 C orbit.

A large number of small intelligent warships more than ten meters were released, but the high-energy light on the fleet still did not stop. They only reduced their energy and bombarded the wreckage of Tianwan SiC. Only by verifying the fine material wreckage with high-energy light inspection will the small warship flexibly rush up and collect the broken wreckage back with the capture net.

"God Lord, what should I do if this is the case?"

On Xingtu, the divine guinea pigs turned around and asked Xu Xiaobai helplessly when they saw this scene.

“…”

Xu Xiaobai also felt a little tooth pain. This time the Octopus Civilized Fleet was so cautious that it was home. This method directly turned the space thunder and lurker arranged by Xu Xiaobai into decorations, becoming a pig and sheep to be slaughtered.

Originally, Xu Xiaobai had already smashed the remains of Tianwan Si C to pieces, and almost none of them had a diameter greater than 50 meters. Now, judging from the other party's attitude, he planned to continue to screen all slightly larger material remains with high-energy light before collecting them back.

According to the study of the third-level civilization, the energy engine of the third-level civilization is no longer fusion, but has become fission.

By controlling the precise use of nuclear force, all matter with atomic mass exceeding iron can be directly fissed into iron at one time, and the part of the mass higher than iron can be directly converted into energy.

According to the original material composition data of Tianwan 4 C, about 28% of the elements are heavy than iron. If you continue playing like this, the opponent's energy will be fully replenished. As for the remaining substances that are not cost-effective for fission and fusion, they can be used as material raw materials, enough to meet the needs of the fleet.

After hesitating, Xu Xiaobai said to the teenage mice: "Control some large space mines to adjust the internal structure, hide possible artificial traces, and move differently after being smashed, quietly reorganized, and was sent back to the warship and exploded again!"

This is the benefit of modular cells. Even if they are broken, they will only die directly from the broken cells. Other cells can still survive, but adjusting the structure and gene recombination is not without cost. If you change this a few times, in the end, the power of space thunder is only one-tenth of the remaining power.

This method poses little threat to the Octopus civilization fleet, because currently only 800-meter and 600-meter warships are involved in the collection of materials. Xu Xiaobai only hopes to break through this and interrupt the other party's steady plan and force the other party to return to the frontal battlefield.
