Chapter 495

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

Sea support fleet.

The commanders of the first and second sub fleets were discussing the tactical arrangements and contingency measures after arriving at the wormhole battlefield. At this time, they received a message from the communication officer at the same time.

"Sir, commander ISAR sent a warning that we should pay close attention behind us!"

"Behind?" they were stunned.

Soon after, they really caught an abnormal target from the gravitational radar.

"Sir, an unknown celestial body is found behind the fleet. It is 68 million kilometers away and has a great mass. It is rushing towards us at an amazing speed. It is expected to come into contact with our fleet in 10 hours!"

Unknown object? Everyone looked suspiciously at the sudden signal on the radar.

"Is it a wandering celestial body?"

"It should not be. We have established a complete celestial body operation monitoring system in the adjacent galaxy. There should be no celestial bodies at this location! Moreover, celestial bodies with this speed and mass belong to class III hazard sources and cannot be ignored by us!"

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

The eyes of the two sub fleet commanders flashed incredible eyes

An hour later, the fleet's optical radar finally captured the target picture. What was displayed in front of everyone was a... Green umbrella?!

Tens of thousands of square kilometers of green umbrella cover obscures all the optical information behind the target, so that they can't see the whole picture of the target.

"Is that it?"

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

Both commanders had a dignified look on their faces.

That biological fortress... Actually caught up?!

After the extreme gravitational acceleration of the star, the elder has obtained considerable sailing speed. In addition to the original high-power propeller group, Nie Yun also provides an additional thrust for the elder again.

If the sea family fleet can observe the back of the umbrella cover, it will find that the newly grown leaves of the elderly have been plated with a layer of bright silver, which reflects a little light under the illumination of the stars behind, adding a bit of dreamlike extraordinary color to the elderly.

This coating is only one layer of mechanical insect total reflection film. The mechanical insect material is insignificant, but a "super solar sail" is produced!

Light is a photon without static mass but with momentum. When the photon strikes a smooth plane, it can change the direction of motion like a table tennis ball bouncing back from the wall and give the hitting object a corresponding force. This is the design principle of the solar sail.

Kepler, a famous astronomer, put forward the hypothesis of solar sail 400 years ago.

The closer you are to the star, the more powerful the solar sail is!

In fact, the "Torch" series of energy collection devices located in the orbit of the sun and stars in the Prometheus plan make use of the strong thrust of photons to compete with the huge gravity of the stars, so as to maintain their 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 make the flying object get a steady stream of powerful power in space without resistance!

For captain Nie, who prefers sail design, this is a cost-effective way of working fluid free propulsion, which provides an additional 10% acceleration for the elderly, so that he can catch up with the latter before the two fleets of the sea family meet in a short time.

This, of course, greatly exceeded ISAR's expectations.

According to her original plan, it was to let the Sea Fleet stare at the wormhole of the solar system and free up their own hands to solve the biological fortress and remove the unstable factors.

But now, looking at the situation in the neighboring galaxy, the first and second sub fleets of the sea family are on the way to the wormhole battlefield for support. Behind them, there are fierce and constantly chasing elders.

Behind the elder, there are the first and second sub fleets of the Yu nationality.

The three are chasing each other on the same channel and want to win the strategic initiative. All mobile forces form a straight pursuit chain

The wormhole of the solar system and the space port of the second planet are undoubtedly the current basic disks of Nie Yun and Gemini respectively, and are also strategic places for defense of both sides.

Nie Yun's loss of the wormhole is equivalent to being cut off and the reinforcements are cut off. The loss of the space port on the Gemini side is basically equivalent to burning the granary and cutting off logistics.

No matter which side loses its "base camp", the victory of the war is basically divided.

According to the current situation, the forces of both sides are moving towards the wormhole of the solar system. The difference is that Nie Yun is on the defensive, the eldest belongs to the back defense, while the forces of Gemini are dominant and on the offensive, which is completely pressing the military line opposite.

At present, those who "guard the tower" are Nie Yun's mecha regiment and... Er, Nie Yun's "Yu Third Fleet"

Well, Nie Yun, who ignored cheating and "stealing the tower", and the "silver revolution" quietly breaking out inside the spaceport at this time, at least in ISAR's eyes, her own base camp is at ease.

However, as the attacking side, the current situation is really not optimistic, because the other side's Space Fortress has completed an extremely thrilling small angle "curve overtaking", which is about to collide with the first and second sub fleets of Hai family in advance!

ISAR naturally couldn't watch the two opposing forces successfully complete the meeting, and immediately ordered the two sea sub fleets in front to stop each other's biological fortress, and it's best to annihilate it!

But the two sub fleet commanders of the sea clan obviously resisted this order

"What should we do now?"

"The appointment of the military headquarters has been issued. ISAR is now the supreme commander of the Corps. We can't disobey her orders, but can only execute them!"

"It's like this again. We rushed to the front, but they watched the excitement behind. The combat effectiveness of the enemy's biological fortress is unknown. We intercepted it rashly. In case of heavy losses, didn't we let the guys of the Yu nationality pick peaches in vain?"

"Well, we have to defend, but we still have to make a gesture. Let's focus on temptation first. If something can't be done... It's not that our army doesn't work hard, but that the enemy is too cunning."

"Ha ha! OK, that's it!"

……

Ten hours passed, and the distance from the elder was finally close to the range of the sea fleet!

"Fire!"

The waiting Sea Fleet immediately launched an attack. More than 40 warships of all kinds launched a salvo, and all kinds of beams of light carried the power of destroying the sky and earth towards the elders!

Because the large umbrella cover completely obscures the body of the elder, the attack line of sight of the Hai nationality is blocked and can only shoot according to the approximate direction judged by the radar, so this wave of attack is slightly scattered.

And the elder who has been silent also moved at the next moment when the sea clan launched an attack!

Its canopy quickly closed, and quickly changed from a large open umbrella cover to a sharp conical arrow. Then the leaves turned together, 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 specular armor!

Due to the rapid reduction of the attack section, a large number of attacks by the Sea Fleet failed, and less than 10% of the attacks hit the elders.

Various rays penetrated layers of protective blades, but were weakened layer by layer. After breaking through more than a dozen layers of protection, they were finally blocked!

However, several more penetrating heavy force field rays did not enter the body of the elder, but they could not see any attack effect because of the shelter of the tree crown.

At the next moment, the elder quickly covered the damaged area when the branches were dancing, and no damage could be seen on the surface

"This... This is impossible!"

All the sea family officers who saw this scene were stunned.

They imagined that the other party might turn on the super shield to stop all attacks, or sacrifice some secret defense weapons, but they never thought that the other party would choose hard resistance!

With his body alone, he carried his own round of Volley?!

What a powerful physical defense?
