Chapter 494: Solar sail

Time passed slowly, a day passed quickly ...
The sea support fleet.
The commanders of the first and second squadrons were discussing the tactical arrangements and contingency measures after arriving at the wormhole battlefield. At this time, they also received a message from the communications officer.
"Sir, Commander Isal sent a warning, asking us to pay close attention to behind us!"
"Behind?" Both were stunned.
Soon afterwards, they really caught an abnormal target from the gravitational radar.
"Sir, the unknown celestial body is found in the rear of the fleet at a distance of 68 million kilometers. The mass is very large. It is rushing towards us at an alarming speed. It is expected that it will come into contact with our fleet in 10 hours!"
Unknown celestial body? Everyone looked suspiciously at the sudden signal on the radar.
"Is it a wandering celestial body?"
"It should not be that we have established a complete celestial operation monitoring system in the Proximity Galaxy. There should be no celestial bodies in this position! Moreover, celestial bodies with such speed and mass belong to the third-level danger source and cannot be ignored by us!
Since it is not a wandering celestial body, then ... there seems to be only one truth!
In the eyes of the two squadron commanders, incredible eyes flashed ...
After 1 hour, the fleet's optical radar finally captured the target picture and displayed it in front of everyone. It was a ... green umbrella? !
Thousands of square kilometers of green umbrella covers obscure all the optical information behind the target, making them unable to see the full picture of the target.
"Is that it?"
"Although the image has changed, but ... it can only be it!"
Both commanders had a dignified look on their faces.
That biological fortress ... was it really catching up? !
After accelerating through the star's ultimate gravitational acceleration, the longevity has obtained a considerable speed of navigation. Not only that, in addition to the original high-power thruster group, Nie Yun also provided an additional thrust for the longevity.
If the Hai family fleet can observe the back of the umbrella cover, it will be found that the blades regrown by the elders have been coated with a layer of bright silver, and the stars behind them reflect the little light under the shining of the stars, adding to the longevity. A bit of dreamlike extraordinary color.
This kind of coating is a total reflection film of mechanical insects with only one layer of thickness. For this reason, the mechanical insect materials consumed are insignificant, but one side is created-"Super Solar Sail"!
Light is a photon that has no static mass but has momentum. When the photon hits a smooth surface, it can change the direction of movement like a ping pong ball bounced back from the wall and give the impacting object a corresponding force. It is the design principle of solar sail.
The famous astronomer Kepler proposed the hypothesis of solar sails 400 years ago.
And the closer to the star, the stronger the propelling effect of the solar sail!
In fact, the "torch" series of energy collection devices located in the Sun's star orbit in the Prometheus plan used the strong thrust of photons to compete with the star's huge gravitational force, which maintained its stable low-orbit operation.
The thrust generated by a single photon is extremely small, but when the area of ​​the solar sail is large enough and the coating reflection effect is super strong, the solar sail can enable the flying object to get a continuous and powerful power in the space without resistance!
For Captain Nie, who prefers sail design, this is a kind of effortless propulsion method, which provides an extra 10% acceleration for the long-lived, so that he can catch up in a short time and catch up with the Hai people. The two fleets catch up with the latter before converging.
And this, naturally exceeded Isaal's expectations.
According to her original plan, the sea clan fleet was to stare at the wormhole of the solar system, and he first freed up his hand to solve the biological fortress and remove the unstable factors.
But now looking at the situation of the neighboring galaxy, the first and second squadrons of the Hai clan are rushing to the wormhole battlefield for support. Behind them, they are the immortal men who are constantly chasing them.
Behind the longevity is the first and second squadrons of the Yu clan who are hotly pursued.
The three of you are chasing and chasing on the same channel, and you all want to gain strategic initiative. All the mobile forces form a straight pursuit chain ...
The Solar System Wormhole and the Second Planet Space Port are undoubtedly the current basic disks of Nie Yun's side and Gemini's side, respectively, as well as strategic points of defense for both sides.
Nie Yun ’s loss of the wormhole is tantamount to being cut off and the reinforcements cut off, while the loss of the spaceport on the Gemini side is basically equivalent to being burned to the granary and the logistics cut off.
No matter which side loses its "base camp", this war will basically be divided.
According to the current situation, the forces of both sides are moving toward the wormhole of the solar system. The difference is that Nie Yun is on the defensive, the longevity belongs to the defense, and the Gemini star is dominant and is on the offensive. line.
At present, the "guard tower" is Nie Yun's Mecha Corps and ... well, Nie Yun's "Yu Clan Third Fleet" ...
Well, Nie Yun, who ignores cheating "stealing towers," and the "Silver Revolution" that is quietly erupting inside the space port at this time, at least in the eyes of Isaar who is unaware, his own base camp has no worries.
But as the attacking side, the current situation is really not optimistic, because the other's Battlestar has completed an extremely thrilling small angle "overtaking" in the corner, and will soon collide with the first and second squadrons of the Hai family!
Isar naturally couldn't just watch the opposing two troops successfully complete the division, and immediately ordered the two sea clan squadrons in front of them to stop the biological fortress of the opponent, preferably to destroy them!
However, the two commanders of the squadron of the Hai tribe obviously resisted this command ...
"What should we do now?"
"The appointment of the military department has been issued, and Isar is now the supreme commander of the legion. Her orders cannot be disobeyed, and can only be executed!"
"This is also the case. We charged, but they were watching the back. The enemy's biological fortress combat power is unknown. If we hurriedly intercepted in this way, in case of heavy losses, wouldn't the gang of the Yu people pick peach in vain?"
"Well! I have to defend, but we still have to do the gesture. Let's focus on temptation first. If nothing can be done ... then it is not because our army does not work hard, but the enemy is too cunning."
"Haha! Okay, just do it!"
...
After 10 hours, the distance to the longevity finally reached the range of the Hai family fleet!
"Fire!"
The squadrons waiting for the battle immediately launched an attack, a round of volleys of more than 40 various warships, and various beams carried the power of destruction to the longevity!
Because the large umbrella cover completely covered the body of the longevity, the attack sight of the Hai tribe was blocked, and it was only possible to shoot according to the general direction judged by the radar, so this wave of attack was slightly scattered.
And the immortal who has not been moving has moved the next moment the Hai clan launched the attack!
Its canopy quickly gathered up, quickly transformed from a large open canopy into a sharp cone-shaped arrow, and then the blades were turned over, and the overall color changed from dark green "brush" to bright silver.
The super solar sail designed by Nie Yun can not only be used as a booster, but also instantly become a set of mirror reflective armor!
Due to the rapid reduction of the attack cross-section, a large number of attacks of the Hai family fleet failed, and only less than 10% of the attacks hit the longevity.
Various rays penetrated through layers of protective blades, but were weakened layer by layer, and finally penetrated after dozens of layers of protection!
However, several rays of the heavy force field with stronger penetrating power did not enter the body of the longevity, but because of the cover of the tree crown, they could not see any attack effect.
At the next moment, during the dancing of the longevity, the damaged area was quickly re-covered, and no damage was seen on the surface ...
"This ... this is impossible!"
All the Hai nationality officers who saw this scene were stunned.
They imagined that the other party might open a super shield to stop all attacks, or offer some secret defensive weapons, but they never thought that the other party would choose hard resistance!
With his body alone, he carried his own round of salvo? !
How powerful is this physical defense?
