The edge of the solar system.
A huge fleet of Star Destroyer Motherships slowly emerged from the opened small wormhole.
In this quiet, dark and profound space, it looked extraordinarily weird.
If you look carefully, you can also find that there are around and directly in front of these one hundred and fifty giant star destroyer ships.
In fact, there are countless aircraft that look much, much smaller.
They were unleashed by these star destroyer motherships, small space fighters, and bombers.
Flying at the forefront of the team are some space reconnaissance planes, spy spacecraft and so on.
In addition, there are some targets that are completely invisible to the naked eye and energy detection radar, and cannot be searched.
They had flown quietly over the ambush area.
It is continuing to sail in the direction of the civilization of the earth.
These stealth transport planes.
It was the commandos of the Bright Pirates that were carrying them.
That is, the special forces of aliens.
They're going on a beheading mission.
An assassination operation was carried out against Li Chen, the leader of the earth civilization, who is also the top speaker of the star shelter.
At the same time, it is also responsible for destroying the main anti-aircraft weapons of earth civilization.
In their view, once the special forces have completed these tasks.
Then the next earth civilization will be nothing more than that.
It's just a plaything that they can handle at will.
Among the vast sea of stars.
All these pictures just flashed before the eyes of the ambush troops in the star refuge.
In the next second, they all entered the invisible state again.
"Don't do it yet, let them go."
"Let's treat them to a dumpling meal later!"
The sound of Noah No. 1 rang in the ears of every pilot of an aerospace super stealth fighter and bomber.
Under the command of this interim commander with strong intelligence capabilities and rich combat experience.
Divided into multiple batches of super stealth fighter formations for ambushes at multiple designated locations.
Silently follow the movement of the huge fleet of the enemy.
At the same time, continue to cooperate with other ambush forces to narrow the encirclement.
…
the other side.
[Host, since the enemy is a pirate group, attacking a planetary civilization will inevitably adopt assassination tactics, after all, the king is captured first before the thief is captured. 】
[So I think, you should not send Megatron to patrol at this time, but let him stay by your side for protection...]
Noah reminded Li Chen in his mind.
Because Li Chen had just sent Megatron out and arranged for him to participate in the outer patrol mission of the entire star refuge.
In fact, the main thing is to patrol an area equivalent to Y plus province A.
Although the whole earth has been refined.
But everything they created on the ground is still there.
Super canopy and super protective barriers, as well as the super urban agglomeration built in Province Y.
It's just that now they have turned into falling on the surface of the outer shell of the star shelter.
Although also in a stealth state.
There is a high probability that the enemy will not be found.
However, everything is not afraid of 10,000, just in case.
The protection of the super canopy and the super barrier has an upper limit.
If the enemy intends to break into the star shelter.
That would be a good area to choose.
"Don't worry, Noah."
"I can't wait for those enemies to come to the door!"
"Exactly, I also want to fight aliens!"
Li Chen looked confident.
As soon as he finished speaking, suddenly, the ultra-high-power energy detection radar inside the star shelter issued a piercing siren.
【warn! warn! A large ultra-high energy body has been detected near the moon! 】
【warn! warn! A large ultra-high energy body has been detected near the moon! 】
[Locking on the target, confirming the identity of the target...]
…
The energy detection radar of the star shelter can detect very far.
At the same time, it also has a certain anti-stealth ability.
But only if the target is within close range of the star shelter.
This kind of anti-stealth ability can play a role.
At this moment, hear these sirens.
Li Chen immediately called up the monitoring screen near the moon.
They have long been on the moon and deployed a large number of monitoring equipment.
Even in the nearby starry sky.
Stealthy spy robots are also set up.
At this moment, by observing the pictures taken back.
Li Chen and others did not find any abnormality at all.
Both high frame rates for full resolution photos.
It is still a high frame rate surveillance video screen.
All they saw was the vast expanse of starry sky and the silently operating moon.
Other than that, nothing was found.
[Host, the enemy is still in an invisible state, but they are too close to us, so even if they are invisible, the energy source on their aircraft will continue to emit energy. 】
[Although this energy is already very weak, it was still captured by our energy detection radar. 】
Noah analyzed.
The detection principle of energy radar is simple in fact.
But it's really complicated to describe.
In short, it is to capture the tiniest energy changes, amplify them, and then analyze and judge them through super computing power.
Finally confirm the type of target, and then lock the position of the target.
Because different objects have different energies, the same object has different energy strength and even forms in different states.
Li Chen nodded.
"It seems that this is the enemy's task force."
"That's the 'alien special forces' you said came to assassinate me."
At this time, several very, very faint light spots appeared on the search screen of the energy detection radar.
That is the location of the enemy's stealth aircraft.
Judging from the distance, they have left the vicinity of the moon and are continuing to approach the earth's atmosphere.
The current distance is less than 150,000 kilometers.
"Noah, turn off all high-power energy detection radars."
Li Chen suddenly ordered.
Hearing this, Noah was slightly taken aback, a little puzzled.
[Host, why did you do this? 】
Li Chen just raised the corners of his mouth, revealing a playful smile.
Then he narrowed his eyes and explained.
"Since the enemy will be detected by our radar because of the thermal radiation emitted by themselves or the aircraft they are riding on."
"When those high-power and ultra-high-power radars are running, they also emit the same heat radiation. Do you think they will find us?"
Li Chen smiled.
However, Noah gave him a very positive, but unexpected answer.
[Host, they won't. 】
Noah answered directly without any hesitation or thinking.
"oh?"
Li Chen was very surprised.
[Did you forget, what level is the star shelter currently? 】
[The star refuge is a refuge of thirty stars. 】
Noah reminded.
