Time passes slowly, and the time of the day passes quickly......

Sea Tribe Support Fleet.

The commanders of the 1st and 2nd fleets were discussing tactical arrangements and contingency measures after arriving at the wormhole battlefield, when they received a message from the communications officer at the same time.

"Sir, there's an alarm from Commander Ishal asking us to keep an eye on our back!"

"Behind you?" Both of them were stunned.

Soon after, they actually caught an anomalous target from the gravitational radar.

"Sir, an unknown celestial body has been found in the rear of the fleet, 68 million kilometers away, with a large mass, and it is rushing towards us at an alarming speed, and it is expected that there will be contact with our fleet in 10 hours!"

Unknown celestial bodies? Everyone looked at the signal that suddenly appeared on the radar with some suspicion.

"Is it a wandering celestial?"

"Probably not, we have established a complete celestial body operation monitoring system in Proxima Centauri, and there should be no celestial bodies in this position! Moreover, a celestial body with this speed and mass is a third-level source of danger, and it is impossible for us to ignore it! ”

Since it is not a wandering celestial body, then ...... There seems to be only one truth left!

The eyes of both squadron commanders flashed in disbelief......

One hour later, the fleet's lidar finally captured the target picture, and what was shown in front of everyone was a ...... Big green umbrella?!

Thousands of square kilometers of green umbrella cover obscured all optical information behind the target, making it impossible for them to get a full view of the target.

"Is that it?"

"Although the image has changed a little, it is ...... It can only be it! ”

Both commanders had solemn expressions on their faces.

The creature fortress...... Did you really catch up?!

The Immortals had gained considerable sailing speed after being accelerated by the extreme gravitational pull of the stars, and not only that, but in addition to the original high-power thruster set, Nie Yun also provided the Immortals with an additional thrust again.

If the Aqua Fleet could look at the back of the canopy, they would see that the blades regrown by the Immortals had been plated with a layer of bright silver, reflecting the light of the stars behind them, adding a bit of dreamlike transcendence to the Immortals.

This coating is a fully reflective film of mechanical insects with a thickness of only one layer, and the mechanical insect material consumed for this purpose is insignificant, but it creates one side - "Super Solar Sail"!

Light is a photon that has no static mass, but has momentum, and when the photon hits a smooth plane, it can change the direction of motion like a ping-pong ball bouncing off the wall, and give the corresponding force to the impacting object, which is the design principle of the solar sail.

The famous astronomer Kepler proposed the hypothesis of the solar sail 400 years ago.

And the closer you get to the star, the more powerful the propulsion of the solar sail becomes!

In fact, the Prometheus Project's "Torch" series of energy harvesting devices located in the orbit of the sun's stars uses the strong thrust of photons to compete with the huge gravitational pull of the star, which maintains its own 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 give the flying object a steady stream of powerful power in space without resistance!

For Captain Nie, who prefers sail design, this is a cost-effective and costless form of work-free propulsion, providing the Immortals with an additional 10% acceleration in order to catch up with the two fleets of the Sea Clan in a short period of time.

And this, naturally, greatly exceeded Isar's expectations.

According to her original plan, she had the Sea Clan fleet staring at the wormhole of the solar system, and she would free up her hands to deal with the biological fortress and eliminate the unstable factors.

But now looking at the situation in Proxima Centauri, the first and second fleets of the Sea Clan are on their way to the wormhole battlefield to support, and behind them are the immortals who are constantly chasing after them.

Behind the immortals, there were the first and second fleets of the Yu Clan in hot pursuit.

All three are chasing each other on the same waterway, and they all want to gain the strategic initiative, and all mobile forces form a straight chain of pursuit......

The wormhole of the solar system and the spaceport of the second planet are undoubtedly the current basic disks of Nie Yun's side and the Gemini side, respectively, and they are also strategic points for the defense of the two sides.

Nie Yun's loss of the wormhole is equivalent to being cut off from the back road and cutting off reinforcements, while the loss of the spaceport on the Gemini side is basically equivalent to being burned down and the logistics are cut off.

No matter which side loses its "base camp", the war is basically won or lost.

According to the current situation, the forces of both sides are advancing towards the wormhole of the solar system, the difference is that Nie Yun is on the defensive, the immortals belong to the defense, and the twin stars have the advantage of forces and are on the offensive, which is completely pressing the line of troops on the opposite side.

At present, the "towers" are Nie Yun's mecha corps and ...... Uh, Nie Yun's "Third Squadron of the Feather Clan"......

Well, ignoring Nie Yun, who cheated and "stole the tower", and the "Silver Revolution" that was quietly breaking out inside the spaceport at this time, at least in the eyes of Ishar, who was unaware, his own base camp was at ease.

But as an attacker, the current situation is really not optimistic, because the opponent's Battlestar has completed an extremely thrilling small-angle "corner overtaking", and is about to collide with the first and second fleets of the Sea Tribe in advance!

Naturally, Ishar couldn't watch the two opposing armies successfully complete the meeting, so he immediately ordered the two Sea Clan fleets in front to stop the other party's biological fortress, and it was best to annihilate them!

But to this order, the two commanders of the Sea Clan's detachment were obviously somewhat resistant......

"What do we do now?"

"The appointment of the military department has been issued, and Ishar is now the supreme commander of the legion, and we cannot disobey her orders, we can only carry them out!"

"Again, we charged, but they were watching the excitement from behind, the enemy's biological fortress combat effectiveness is unknown, we intercepted it so rashly, in case of heavy losses, wouldn't it be in vain to let those guys of the Yu clan pick peaches?"

"Hmmm! We have to take precautions, but the posture still has to be done, we first focus on temptation, if it is impossible to do something...... Then it's not that our army doesn't work hard, but that the enemy is too cunning. ”

"Haha! Okay, that's it! ”

……

Ten hours flew by, and the distance with the Immortals was finally within the range of the Sea Clan fleet!

"Fire!"

The Sea Clan fleet, which was in full array, immediately launched an attack, and a salvo of more than 40 warships of all kinds was fired, and all kinds of beams carried the power of destroying the world towards the immortals!

Since the large umbrella cover completely obscured the Immortals' body, the Sea Clan's attack line of sight was blocked, and they could only shoot according to the general direction judged by the radar, so this wave of attacks was slightly scattered.

And the immortals, who had been motionless all this time, also moved the next moment when the Sea Clan attacked!

Its canopy quickly retracted, transforming from a large open canopy into a sharp, conical arrow, and then the leaves flipped in unison, and the overall color changed from dark green to bright silver.

This super solar sail designed by Nie Yun can not only be used as a booster, but also instantly turn into a set of mirror reflective armor!

Due to the rapid reduction of the attack cross-section, a large number of attacks by the Sea Clan fleet missed, and less than 10% of the attacks hit the Immortals.

All kinds of rays pierced through layers of protective blades, but they were weakened layer by layer, and they were finally blocked after penetrating more than a dozen layers of protection!

However, several heavy force field rays with stronger penetrating power submerged into the immortal's body, but because of the obscuration of the canopy, no attack effect could be seen.

In the next moment, the branches of the Elder danced, quickly covering the damaged area again, and no damage was visible on the surface......

"This ...... That's impossible! ”

All the Sea Clan officers who saw this scene were stunned.

They had imagined that the other party might open the super shield to block all attacks, or sacrifice some secret defensive weapon, but they never thought that the other party would choose to resist hard!

With his body alone, he carried a salvo from his own side?!

How strong is this physical defense?
