Ten projectiles, one large and nine small, directly hit the Orca-class battleship as a target ship at a speed infinitely close to the speed of light, setting off waves on top of the energy shield.

It stands to reason that the rail cannon definitely doesn't have that much power to make the energy shield of a killer whale-class battleship make waves.

According to Bai Zixuan's previous statement, the ten rail launches of this new rail cannon are specially arranged, and can ensure that ten projectiles hit at the same time, and the energy formed by the impact will resonate with each other, which will cause great damage to the energy shield.

"Commander, the target ship sent back a message that the energy shield was depleted by 12%!"

The tester was also very excited when he reported, he didn't expect this old-fashioned weapon to have such power, should he be said to be the chief scientist of mankind, Bai Zixuan, Bai Lao?

"Not bad, how soon can I shoot again?"

Lin Fan listened to the tester's report, nodded with satisfaction, and continued to ask.

"Since it uses physical ammunition, it needs to be reloaded after firing, and the reloading speed is about 15 seconds, but at present, this rail gun is mounted on the battleship, and there is no problem with charging, but if it is operated independently, it needs to provide a powerful energy source!"

Hearing this, Lin Fan frowned, this is a big problem!

You can't install a fusion reactor for every rail gun, that's too.

But if this is not the case, how to power the rail gun?

Wait, there you have it! Laika Crystal, yes, with Laika Crystal (the energy crystal of the Laika Empire, named Laika Crystal by humans)!

Laika Crystals have been specially tested before, and each full charge can be used for a high-intensity battle on a Killer Whale-class battleship of the Federation.

If it is only used on a new rail gun system, it will definitely be used for many years, and it is still in the case of heavy use!

Besides, this thing has a huge reserve in the Laika Capital Area, and there are huge reserves on almost every resource star, and according to the results of exploration, there are at least 10 trillion Lycra crystal deposits in the entire Laika Capital Area.

As for the price of the Federal Lycra acquisition, it is quite cheap, only 10 points each, which is no different from grabbing it for nothing.

Today, the Laika Empire mined about 100 million yuan a year, and sixty percent of them will be acquired by the Federation, which has acquired more than hundreds of millions of Lycra crystals so far.

"Is it feasible to use Lycra crystal as an energy source?"

Lin Fan asked the tester, after all, he is not a professional, and he still needs to let the professional confirm before he can rest assured!

"Commander, it's definitely okay to use Lycra Crystal, but we don't have Kalai Crystal here, so we need to deploy it from the earth!"

"You don't have to worry about this! Liang Xue, help me contact the earth, I need a lot of Lycra crystals, let them prepare 50 million for me! ”

"Understood!"

"Look, the problem is solved!"

After instructing Liang Xue, Lin Fan turned his head and looked at the tester with a smile!

The tester and several of his assistants were a little stunned for a while, 50 million Lycra crystals seemed to be a matter of one sentence in the eyes of the commander!

And just let the deputy go and notify it, and he can't even bother to show up?

Is this the big guy of the interstellar age?

"Okay, come back to your senses, after you go back to the scientific research city, talk to Bai Lao! The Laika Crystal will be delivered in a few months, so that he can make some modifications to the energy system, and at the same time design the thruster for attitude control that I told him earlier, and then start mass production! ”

"Okay, Commander, is there anything else I need to tell me?"

"No, so be it!"

Lin Fan won't admit it, the reason why you want to tell it is because he is afraid that he will be sprayed by Bai Zixuan again in the past!

After finishing speaking, he immediately left with Liang Xue.

After finishing the matter of the rail cannon, Lin Fan took Liang Xue and began to check the construction progress of the star defense network, after all, this is also one of the important means of this battle.

The so-called star defense network is composed of tens of millions of fixed defense platforms and a star cannon.

The structure of the entire defense network is a complex three-dimensional mesh structure, with a total of 13.8 million nodes, each of which is a fixed defense platform.

【Fixed Defense Platform (Remote Control Type)】

Level: Defensive platform

Tonnage: 200,000 tons

Hull dimensions: length 382 meters, width 235 meters, height 120 meters

Main armament: Triple 15m caliber plasma cannon, quantity 1

Secondary Armament: Twin 3m caliber male cannons, quantity 4

Close-in weapons: rapid-fire electromagnetic catapult cannons, quantity 16

Other weapons: multi-purpose missile silos, number 128

Defenses: Gen 3 Energy Shields

Number of Passengers: None (Remote Control Type)

As can be seen from the data, the so-called defense platform is actually a small warship that cannot move without an engine.

It has a triple plasma cannon on a Killer Whale-class battleship and four twin positive electron cannons, which can be said to have this good attack ability!

Although the single body is still far behind the Orca-class battleships in terms of firepower, the key is that there are enough of them, and the entire star defense network is full of 13.8 million defense platforms.

Although this is already very powerful, the defense platform is not the focus of the star defense network, the real core is the star cannon.

And its real name is [Nuclear Explosion-Induced Gamma Ray Launcher], which is a long-range gamma ray cannon, which belongs to the weapon of the early level 5 civilization, and is generally used as a fortress cannon for important strongholds.

This is a weapon of mass destruction in the interstellar age, once launched, on a ray with a diameter of about 2 million kilometers, there will definitely be no live wounds left, not even an energy shield to block the slightest.

But there are also major drawbacks, this weapon recharges extremely slowly, only firing once every thirty minutes.

In addition, the size of the Star Cannon is also very large, almost the size of ten battleships, so it is necessary to have a large number of battleship guards to keep the enemy out of range at all times, so that they cannot attack the Star Cannon, otherwise, the Star Cannon will never be able to fire a second cannon!

Normally, a level 4 civilization can't afford to play with a starry cannon, after all, the energy consumption of this thing is too terrifying, even if you set up dozens or hundreds of nuclear fusion reactors, they can't keep up with the energy required to charge them.

However, because of the Lycra Crystal, the Starry Sky Cannon is possible, and in its internal energy chamber, 100,000 Lycra Crystals full of energy are stored.

Each time the Starry Sky Cannon is recharged before firing, it consumes the energy stored in the entire 10,000 Lycra Crystals.

In other words, the Starry Sky Cannon can be fired up to ten times in wartime, not that humans are reluctant to have more Laika crystals for backup, but it is completely unnecessary!

Because normally, you won't have a chance to fire ten times!

Before you launch ten times, you'll either have already killed the opponent or you'll be killed by the opponent!
